Cannot Access SQL Server When Using Controls Graphically
Nov 3, 2006
Hi,
i wrote a simple program to access a SQL Server 2005 DB and i use the following connection string:
<connectionStrings>
<add name="Alunos" connectionString="Data Source=.;Initial Catalog=ALUNOS;integrated security=true"/>
<add name="Escola" connectionString="Data
Source=.SQLEXPRESS;Initial Catalog=Escola;integrated
security=true"/>
</connectionStrings>
It all works fine.
Then
i try to create a SQLDataSource object graphically and configure it.
when i choosethe instance and DBi choose Test Connection and it gives
the 'Named Pipes Provider , error 40'. I think i solves this problem
because i googled thisand found a lot of info and i did all that.But
the problem remains.
Could it be the a security issue? with the user i´m using to access the DB?
Some help on this would be very appreciated.
Thanks

Hi,
I need to implement SQL server 2005 reporting services in my current project, we will be having a report server for that, now i am really confused ho should I integrate reporting services with my asp.net 2.0 web application.
My requirement consists of using tables, charts and graphs, need to save reports as excel, xml and csv formats and most important thing is report columns are dynamic, user can select/deselect some columns in a particular report.
Can any one help whether i should go for reportviewer in remote processing mode(then how can i pass column information) or should i go for url access or use SOAP API.
URL access looks easy to implement and really bowled out by SOAP API option, and dont know whether reportviewer can fulfill my requirements or not.
Will really appreciate any kind of help....

I have a question about loading data on the page lode event. The question is more conceptual then how to.
Using C#, I would like to make a call to a SQL 2000 Server, with the use of a stored procedure return one row with eleven fields. Then use the data to fill five different controls. There is no manipulation of the data it is just presented as information. With a DataReader and the GetValues method using the resultant array I can fill the controls (or can I), or with a DataSet and the Load method do the same thing. Now this code can be placed in the code behind page or it can be implemented in a class. This is the only page that uses this combination of fields and controls; however I would think a more generic call to the data could be made then pick and chose the fields as needed. What process makes the most sense? Is what I just described even possible (as yet I haven’t tried it)?
As always thanks in advance for any thoughts, comments, and suggestions.

Hi, I am porting a massive VB6 project to ASP.net 2005. Most of the code is fine, however because the original developers used lots of data controls and my own time restrictions I thought to replicate the functionality by using Sqldatasource controls instead.
These data controls are bound to DBtruegrids. The project has has lots of code like...
AdodcOrders.Recordset.RecordCount > 0 or If AdodcOrders.Recordset.EOF or AdodcOrders.Recordset.MoveNext() or
AdodcDetail.Recordset!FieldName
The problem is the sqldatasource control doesn't have a recordset/dataset property which I can access and manipulate, or does it? What should I do to get round these? The project has thousands of lines like this in so its not feasible to rewrite it (although if I could I would!).
Any suggestions please gratefully appreciated.
many thanks

Hi,
I'm using 2005 management studio express.
Can I use the graphical query builder to specify tables from more than one database?
I know I can do this in sql in the format database..table.column but in the query builder it only shows tables from the current database. Can you get around this?
Thanks

I am writing a small program (Visual Studio Express 2008) to help me automate populating a database graphically. The program I am writing will keep track of sales figures state by state on a map of the US. This will be accomplished by using a map of the United States overlaid with a hexagonal grid that represents individual sales regions (hexagons). Each hexagon represents a specific sales region, and there can be many sales regions within a state. This small program will populate the database with data specific to each hexagon that is selected by clicking on it with a mouse. A complete set of row entries should be sent to the database every time the mouse is clicked in a hexagon on my map. This program will capture such information as the center x,y pixel coordinates of each hexagon, row & column location of each hexagon, and the state where the hexagon is located. All of this information (HexX, HexY, RowX, RowY, State) has already been figured out or calculated, except that I need help on how to capture, display, and send this information as a new row entry into my database. I need to populate the database hexagon by hexagon, since which state they are in is determined visually.
Here is what I need to populate my database with:
Hex_No - each unique hexagon needs to have its own unique number 1,2,3,€¦.n. This should be as easy as assigning a counter that starts at 1 and increments until all hexagons have been processed
Hex_X €“ the pixel x value of the center (x,y) of the specific hexagon, which is known by the program
Hex_Y €“ pixel y value of the center (x,y) of the specific hexagon, which is known by the program
Hex_Col €“ column location of this specific hexagon, which is known by the program
Hex_Row€“ row location of this specific hexagon, which is known by the program
State €“ the current state on the map. This will be selected by me (combobox) prior to clicking on each hexagon within a given state
Each of the above is represented by a textbox on a form, except for the State field, which is represented by a combobox. When one clicks on the down arrow of the combobox, one can see that the names of the different states have already been entered and linked to the SQL database. The other textboxes are also linked to a different column in the same database; however they are currently empty due to the fact that this is the very data that needs to be captured by this program. This is what I need for this program to do for every mouse click , once I have moved on to a given hexagon within a given state:
Determine next available Hexagon Number, and assign it to current hexagon, display in textbox, send this as part of row data entry under Hexagon_No column
Capture and display the current hexagon€™s center x, and y (Hex_X, Hex_Y), display this in textbox, send this as part of row data entry under Hex_X, and Hex_Y columns
Capture and display the current hexagon€™s row and column information (Hex_Col, Hex_Row), display this in textbox, send this as part of row data entry under Hex_Col, and Hex_Row columns
Capture and display the current State that is selected manually from the list of database values, send this as part of row data entry under State column
Here is an example of what this program might look like in action:
http://farm4.static.flickr.com/3172/2285817199_d75f230f8d_o.jpg
I am not looking for anyone to write my program, but I would appreciate some ideas on how I can accomplish this. I have figured everything out except the part about displaying the new information on the textbox/combobox form, and sending it to the database as the next row entry. That€™s the part I need help with.
Thanks.

when my ASP.NET 2.0 web site working against MS SQL Server 2000,I Usually have a connection string to the DB, I create a connection, and start working on the data.
While reading about the MemberShip provider of ASP.NET 2.0 (Login control, Forgot password, etc.),I read that it's possible to save the MDF file of the membership controls, within the APP_DATA folder.
But how can it be ? the MDF file must be at the server folder,How can I access this MDF file ? with which connection string ?How does MS SQL Server 2000 syncronize against this MDF file within my APP_DATA folder ?
And by the way, if my hosting company allow me to use 1 db schema of the MS SQL Server 2000 server,Does this method (saving the MDF file within thr APP_DATA folder) allow me to use multiple schemas ?
Thanks.

Hello all,
I am having problems running a stored proc from an aspx.cs file. Basically I want to extract data from webForm controls and create a new record in a DB table. I have watched the "Getting Started" videos on thi site, and the only difference between my code and the code of the demonstrator is the connection string. My conn string:- dataSrc.ConnectionString = ConfigurationManager.ConnectionStrings["ProjectTblConnString"].ConnectionString;Demonstrator conn string:- dataSrc.ConnectionString = ConfigurationManager.ConnectionStrings("ProjectTblConnString");When I debug with the string as shown by the demonstrator the error list reports that ConnectionStrings is a property and I am trying to use it as a mothod, which is fair enough, but I am just confused as how it worked for the demonstrator and not myself. When I debug with the code I used above I get no error, but nothing is inserted in the DB.Also, it looks as if the only class in my aspx.cs file that is actually being executed is PageLoad() - the remainder of the code seems to be ignored. Below is the entired aspx.cs file:- 1 using System;

All,
My ISP does not allow me to remotely connect to my hosted SQL Server DB--how can I use SQLDataSource and other data bound controls in development?
Here are my specs:
IDE: Visual Web Developer Express 2005
Database: MS SQL Server
ASP Version: ASP.NET 2.0
The SQL Server is hosted centrally at the ISP; basically I have been given the connection string parameters.
My question is this:
Do I use two web.config files (one for when I develop locally and one for when I deploy remotely)? If so, how? Will the SQLDataSource control find the connection string defined in web.config on the remote server? I don't want to have to write all of the database code and it would be a big loss of one of the major benefits of using ASP.NET 2.0 if I do.
Any help will be greatly appreciated,
Leslie

Hi,
I downloaeded "Microsoft SQL Server 2005 Datamining Viewer Controls" feature pack, and tried to run the dataminingviewerclient.exe.
When i view my local time series data mining model, It works well for single series model, but when i load a Microsoft time series model containing multiple data series, an unhandled exception occurs.
I post the error message below:

Is it not possible to execute one package and then design another package? I am executing one package and trying to design another package and just have a grey window in the control tool box that says:
"there are no usable controls in this group. Drag an item onto this text to add it to the toolbar"
Can I only get my controls by dragging when another package is executing? Where do I drag them from?
Thanks,

This is pretty weird... any controls past the halfway horizontal point of the report get pushed into page 2. The leftmost control is not affected just those to the right of it. It's like there is an invisible tab after the leftmost control. Smaller (not leftmost controls) (not past the middle of the page) are also pushed way to the right (just not into a new page)
Is there some property (that I'm not aware of) that does this? It doesn't matter if I use textboxes or lines. I have not changed any of the default control properties. flow layout is still LTR.
In my current report I have questions and answers on separate lines...I can't place them next to each other or it screws up the pagination.
I start with a new report and it does not do this but as soon as I add 2-3 vertical pages (over 11' x 2) This starts happening.
Has anyone experienced this?

Hello everyone, I'm trying to get a count of 3 different types on the same field. For Example, let's use Gender as the field with these options: Male, Female, Not Given. What I'm wanting to do is retrieve a count for each type. What I have so far is: SELECT COUNT(Gender) WHERE Gender = 'Male' and I have to duplicate this in 3 different data controls. I would like, however, to have one datasource control with a statement along the lines of: SELECT ( SELECT COUNT(Gender) FROM Users WHERE Gender='Male), SELECT COUNT(Gender) FROM Users WHERE Gender='Female', SELECT COUNT(Gender) WHERE Gender='NotGiven' ) From UsersOr something to that effect. Any suggestions?Thank you greatly for your help,Mark

I created a user control file with 3 properties. I would like to call this user control in a datalist control in the hosting page and pass the properties from a sqldatasource control. To this end I have a code like below;
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"SelectCommand="SELECT [1], [2], [3] FROM [table1]"></asp:SqlDataSource>
<asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1" DataMember="DefaultView" >
<ItemTemplate>
<uc:kk ID="kk1" runat="server" One='<%# Eval("1") %>' Two='<%# Eval("2") %>' Three='<%# Eval("3") %>' /></ItemTemplate></asp:DataList> I don't get any errors when I run the page, however it won't work as I wish. Only thing that appears in the rows of datalist is "01.01.0001 00:00:00".

Hello !
i am new to databases so i would be grateful for your help.
I am using SQL Server 2000 and vb to access and update the records of a database.
I want your opinion about the way i am displaying data.
I have created a form with textboxes etc. which display the fields
of the table.
Now when i load the form i populate a recordset with a
"select ... from... " query.
Then i manually
set
txtfield1.text=cstr(recordset.fields("field1").value)
etc...
If i want to update the table then i have to construct manually the
query.
"update ... set field1='"+ txtfield.text +"' "
if i want to move to a next record i do
recordset.movenext
and then
txtfield1.text=cstr(recordset.fields("field1").value)
again
Is that good or should i use bound controls ?
If multiple users access the same form at the same time (from different computers) will they be locked only when they save (update) data ?
Thank you !

Hi,
i want to create dynamic controls using wpf and c#.
can any body send me some code snippet.
for example:-
one of my window page have 100s of fields like textbox, checkbox and date controls in a group inside different grid and panel.
now if admin has made that amoung 100 fields user should be able to see only 20 or 30 fields.
how will i do so, just making the fileds invisible won't work, coz all the fields should be visible from top of the form,
means i want to push all the visible fields at the top.
what are the best way to do so.
need it urgent
thanx a lot

Hi ... hope you can help.
I would like to use the Data Mining Web Controls which ship with the MSSQL2005 Beta 2. The installer (BetaAnalysisServicesSamples.MSI) is supposed to create a new virtual directory and should also create the DataMiningHTMLViewers.dll according to "ReadMe_Data_Mining_Web_Controls.rtf"
But the MSI only creates a few new directories with the source code and a deployment project (DMHTMLViewersSetup.vdproj) which won't open with VS2003. The solution apears to be for VS2005.
How do I install the Web Controls?

RS 2005
I have a matrix item in a report. It is only about 7cm in width in design mode but obviously explodes out to about 30cm in when the report is run as thats the way the query behind it works.
The problem is any control e.g. a chart placed above and to the right of the matrix in design mode gets pushed across to the end of the matrix's width when the report is run, which causes extra pages in the report.
Other controls placed directly above the matrix in design mode hold their position when the report is run, it is only those controls placed further right than the end of the matrix (and above the matrix) in design mode that get pushed across. Why is this, is there a way to fix it?
Thanks

After resolving all the installation and configuration related issues, I was able to deploy a couple of projects on my report server. I can see alll folders and reports listed inside the folders from http://<servername>/reports . All works fine except when I run a report, the http://<servername>/Reports/Pages/Report.aspx page does not render report.
This page displays View, Properties, History Subscriptions etc, menu items on the top section of the page. It also displays Home, My Subscriptions, Site Settings, Help etc. links on top right corner of the page. I can also see the bar that has "New subscription" button. But the problem starts from the section below that. It does NOT display the Report navigation bottons (like First page button, Next Page button, previous page button, Last page button, print button etc.) Appears that the icons images for these bottons are missing. And above all, the page does not render report.
IE browser status indicate the following error:
error:'HoevrImagectl161_ctl01_ctl01_ctl06_ctl01' is null or not an object.
The report renders fine via http://<servername>/ReportServer/Pages/ReportViewer.aspx
I may not have explained the problem well here however, if you are interested, I can email you the screenshot of Report.aspx to help you understand the problem.
Any help is appreciated!!!

When a ReportViewer control is used to access a report on a remote SQL Server database, on what ports does the communcation occur? Does the control communicate on on the SQL Server ports of 1433 and 1434 or does it communcate as a web service on port 80 (or 443 for HTPPS)?

NET 2.0
I am using Visual Studio Express 2005 for database web developement.
I have created a database with 5 tables. Two are associative tables.
They are
SoftwarePK SoftwareID Title
SoftwareSolutionFK SoftwareIDFK SolutionID
SolutionPK SolutionID Title
CategorySolutionFK CategoryFK Solution
Category
PK Category Title
Criteria for a search with three sources of input into a SqlDataSource attached to a FormView for paged out.
The following are the Search Criteria input sources:1) ListBox in Multiple Selection Mode2) CheckBoxList with Mutiple checks posible2) TextBox with key word search in Title.
Each Solution has 0 or many Categories and 0 or many Software.
When the records are entered in the database, the associative information for Categories and Software are populated to filter thereturned values.
In NET 1.1, I would create a search string like the following in code behind by looping through the CheckBoxList and ListBox finally adding the TextBox:
SELECT Solution.SolutionID, Solution.Title FROM SolutionWHERE Solution.SolutionID IN ('2','3','5') AND Solution.Title LIKE '%Math%'
I am unable to update the SelectCommand in the ASPX page.
However, when I use the I have used theSystem.Web.UI.WebControls.SqlDataSources"SelectQuery Builder"I receive the following in the Source for ASPX: <asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
OldValuesParameterFormatString="original_{0}" SelectCommand="SELECT Solution.SolutionID, Solution.Title
FROM
Solution INNER JOIN CategorySolution ON Solution.SolutionID = CategorySolution.SolutionID
INNER JOIN SoftwareSolution ON Solution.SolutionID = SoftwareSolution.SolutionID">
<SelectParameters>
<asp:ControlParameter ControlID="CheckBoxList1" DefaultValue="%" Name="CategoryID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="ListBox1" DefaultValue="%" Name="SoftwareID" PropertyName="SelectedValue" />
<asp:ControlParameter ControlID="txtTitleSearch" DefaultValue="%" Name="Title" PropertyName="Text" />
</SelectParameters>
</asp:SqlDataSource> I receive duplicate records and not sure if the code generated accesses the Mutiple Selected values in the CheckBoxList1 and ListBox1.Question: 1) If the SelectQuery generator will not access multiple selected values from the CheckBoxList1, how can I use code behind to replaceSelectCommand in the ASPX page?2) What is the best solution for using the CheckBoxList1, ListBox1, and TextBox for filtering my results? Sample code, references to solutions, corrections on logic, a new approach, how to use the wizard correctly would all be greatly appreciated.3) Can Multiple Selection Controls be use with a SqlDataSource SELECT Command?Thanks for your time,Sincerely,Unhistoric

Thanks for your help.
I'm just getting into ASP.NET 2.0 and started using the SqlDataSource control to declaritively connect to a database. I was wondering if I have two SqlDataSource controls on one page with two select commands querying the same database, will the that create to seperate instances of opening and closing the connection to the database, or will it open the database once, execute both queries, and then close the connection. It seems that if it creates two separate connections, it would still be more efficient to to connect to the database programmatically using ADO.NET. You would only need to make one trip to the database, pull down all of your data, and then close the connection.

one of my webpages uses the following sql query to allow the user to search through the database and present the qualifying data in gridview:
SELECT * FROM [Table1] WHERE ([comments] LIKE '%' + ? + '%')
how could i expand this so that the user can also search through the database but instead by searching through another column such as [type]?
thanks in advance
