Writing Directly To A Database Using An SqlDataSource
Jan 31, 2008
Hey all
Im trying to make a system in which users logged on can change their password. I dont want to use a grid view because that dosent give me the chance to let them put in their old password first for validation but now I need a way of takeing data out of the textbox with the new password and placeing it in to the field in a database.
As I stand at the moment I have a data.dataview variable equal to an SQL Data Source with my query in it, bringing back a record from a users table with the users username, password and a field stating what type of user they are. It filters this by username which is stored as a session variable and username is the primary key. there is then an if statement checking that the string in the password field is equal to what the user has written in the old password box and if they match it uses the command:
dv.Table.Rows(0)(1) = txtNewPassword.Text
MsgBox("Password Successfully Changed", MsgBoxStyle.Information)
When I run this the validation successfully checks the password is correct and then displays the message box saying the password is correct but it hasnt actually changed it. Somone I know told me that I need to use the command sqldatasource.update but I cant see where it fits in.
Anyone got any ideas?

it is a type of reporting that i am trying to do
but i just need to export the raw data i retreive from the query

First let me give you a little back ground on me. I'm very new to the ASP, ASP.NET, Visual Studio, Sql Server, Frameworks....thing. I am coming over from a PHP/MySql background of over 5 years. The change over to VBScript and VB has been to tough and I have a basic liking for the Visual Studio 2005 and the ease of putting things together. However, I have come across something that to me seems like it should be relatively simple, but haven't been able to find the documentation or samples to describe what I'm looking to do.
Rough Need:
1. Start with a form will a couple labels and a singe textbox to get the lookup date from an user.
2. Query one table/view based on the users choice of date and select only one field of returned data.(Doing this by itself is not a problem and I can display my results in a Gridview, but this is where it starts getting tricky and the gridviews won't work for me.)
3. If there is something returned, I need to start a HTML table layout or possibly some form of a Gridview(I don't see how I would use the Gridview) and start a loop, adding the first returned row from this query into the first cell.
4. Now, based on that same User Date and the returned row value from the previous query, I need to query another Table/view and return another single field, which might return 1 or multiple rows, which I need to start a loop to display unique items in cells under the first on above.
5. Based on the original User Date and each returned row from the first query, I need to query two other Table/views and get some additional information. 4-5 fields will be returned and be displayed on one row in the number of necessary columns.
6. This would finish the first row from the first query, so I would need to loop back up to see if there were any further results and continue looping until the get to the last of the results from the first query.
7. Finally, I would just need to close up the Table/gridview.
The basic results I'm looking for would be similar to the following:
Results for 10/11/2005
Field name 1
Field name 2
Field name 3
Field name 4
Field name 5
First Result from query 11 of 4 results from Query 2, but only 1 unique result
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3.
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Second Result from query 1First result from Query 2 after looping though the first query Second result from Query 2 after looping though the first query
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3.
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
Info from Query 3
Info from Query 3
Info from Query 3
Info from Query 4
Info from Query 4
It seems me from what I have read and slowly figuring out, is that I should be able to directly access the DataSet returned by four SqlDataSources, one for each of the above querys and then just write my own VB to handle the necessary looping, table format and such. I can easily add the for SqlDataSources to the page and add a Gridview for each one and get 4 separate chunks of info, but can't see a way with GridViews to intermingle the info like displayed above.
So, if it can be done with Gridviews, then I would love to see how that is done. But, if someone could explain to me how I access the DataSets directly that I get from the 4 SqlDataSources, then that would be ok too. I have figured enough out with VB, that I can write the code to do my looping requirements, if I can just access the information I get back. Thanks for reading all the way through this long post.

This is a subset question of one of my other threads, the gist is while using forms authentication, I am trying to enter additional information into another table on the same db as the aspnet_membership tables. I think I need an <asp:SqlDataSource> to do this because it is about the only thing left I haven't tried to get this code to work so any help is appreciated. Environment: sql server 2000, windows server 2003, asp.net 2.0, vb, no GUI<ASP:SqlDataSource id="addedInfo" ConnectionString="<%$ ConnectionStrings:SqlServerConnection %>" InsertCommand="INSERT INTO addInfo(username,email,company,firstname,lastname,phone) VALUES (@username,@email,@company,@firstname,@lastname,@phone)" runat="server" />looking over some of my books and online it says in the connectionStrings that it is supposed to be the database name that goes next to the : but when I try that I get an error that it is looking for the name of the connection string, so I enter the name of the connection string (as above) and nothing happens, which is basically the ongoing event with this whole problem, the form fields (username, email, password) that go into the aspnet_membership tables just fine, I don't have any problems with those, it is getting the additional information into another table that has been stalling me the whole time.So does this sqldatasource look right? Any help is appreciated.

We have a SQL database that uses Active Directory with Windows Authentication. Can users that are members of the Active Directory group that has read/write access to the SQL database create ODBC connections to access the database directly and update the data? They dont have individual logins on the server. They are only members of the Active Directory group that has a login?

hi lads,
what i need to do for my project are as following:
a mobile user send data via GPRS to SQL server Database. then i need to have a method to detect while a particular table is being inserted. and then extract data from table construct a report dynamiclly. what should i do to achieve this goal? e.g. window application, store procedure or trigger ?
PS : client side is a mobile application developed using MCL. i don't in which way he will send all data to SQL server Database, so what i need to do is to monitor new data inserting.
2) how to auto generate and print report directly after record been inserted into the table ? Do i need to import report web service API ? if yes, which one? or i can use other methods e.g. predefine report control view in my window application, turn off pop-up menu while printing a report(I guess)
thanks

Hi, I'm relatively new to SQL and ASP.NET and I'm after some assistance to what I hope is an easily achievable goal.
I need to upload some files (.pdf, .doc, .jpg - whatever) to a directory on my webserver. Once this has been done, I'd like to write some data to an SQL Database Table that will contain information about these files in a datagrid (or something similar) along with a link to download them.
E.g I upload car.jpg which is located at /images/secure/car.jpg and is a photo of car. When a user logs in, they will be shown a datagrid which pulls information from said SQL database and in this datagrid will be something like:
Filename Description Link
car.jpg A pic of a car Download
If anyone is able to help me out with regards to linking to a file from an SQL dB it would be greatly appreciated, and if you require any further information just let me know :)
Ben.

I was all set to build some triggers on some modified date tables when in the last minute I found out that the application (built in C#) was controlling the after update trigger.
Is there a tool you can use in SSMS to see if there is a connection set up like this?

Can someone advise if there is a delay in data being written to the database following a tableadapter.update(datatable) command?
I save transactions which are subjected to the above and then a listview is updated to reflect them.
As I work through all is OK and the transactions appear in view.
I then run a backup through my app using a backup object to do this and this reports all OK
I then close the app and re-open and as as I am in debug the database is empty.
I perform a restore through my app using a restore object and selecting the backup file I created previoulsy which reports all OK
The retore procedure calls application.restart to allow the app to initialise to the restored data.
The problem is quite a bit of my data in missing from the restore as if the last block I did prior to backup never actaully made it to the database?
I also rememeber noting that at times when the update method is performed the actual timestamp on the physical databse is not updated....until I close the app and return to the designer?
So does this mean then prior to performing a backup I have to somehow force the app to ensure it has written all changes to the databse?
Thanks

I am trying to write to a database through C++ with the ODBC stuff. I can connect to and close the database as well as write certain things to it. I am having trouble writing strings or chars to it though. I'm not really a DB programmer and probably won't have to do it in C++ for a long time, so I'm just looking for some quick help so I can move on to other stuff. I know this code probably won't look right either since I;ve only seen this stuff for about 2 days now. Basically I have a string that I want to bind using SQLBindParameter so that I can use it in an ExecDirect statement. Basically when I run the little code snippet below, it writes some crazy character set out. Any help would be appreciated because I really have no clue what I'm doing.
SQLCHAR test1 = 'a';
SQLINTEGER test = SQL_NTS;
retcode = SQLBindParameter(hstmt, 1, SQL_PARAM_INPUT, SQL_C_CHAR, SQL_CHAR,0,0,&test1, 0,&test);

Hi Forum,
I am having a problem writing string values to my SQl database. I have the following code:
Dim pItemDescription As New SqlParameter("@itemdescription", o.ItemDescription)
cmdOrderDetails.Parameters.Add(pItemDescription)
o.Item Description returns the full string as a parameter but when it is written to the database it only writes the first letter in the database field. The column is set up as a VARCHAR with a a field length of 50 which is more than enough. Is there something I am doing wrong or missing out?
Thanks
Rich

Hi,
I have a data structure called 'Quote' which contains a number of different variables and controls ranging from text boxes, check boxes and radio buttons, i need to be able to read and write this from a database.
First I think a description of my overall project is needed:
Project Description
I have been given a brief that basically says: i have to create a programmed solution in VB to solve a problem. This problem can be anything we like, and I personally have chosen to create a program that manages quotes for building Log Cabins (this is very contrived and far from anything someone would do in the real world).
My solution will allow a generic user to create a quote (using a form with controls such as text boxes, check boxes, radio buttons) , and then save this to file. These users may then wish to load/edit this quote at a later date, from another form.
Whilst completing this project, i'll only have up to about 5 records (quotes) within the system, so i dont need the ability to store hundreds of records. And each record will be relatively short, with only about 10-15 data items within the data structure.
Also the Admin (or business owner in this case) need to be able to view all saved quotes in a presentable format, and edit them if needs be, from within this same program.
This solution does not need to be absolutely perfect and 100% efficiently coded, or have all the bells and whistles a real-world program would have. This is for an A level computing project by the way.
So basically, i need to be able to read from the database (to populate a Data Grid (i imagine this is best way?)) and so Admin can access any quote and edit it (editing is not vital, but viewing/printing is. Maybe i should stop at just viewing any quote?). Also i need generic users to be able to fill in the Edit Quote form and then save this data into the database.
And is a data structure really required for me to use a database?
I've never used databases in VB before (but have used them elsewhere, mainly Access) and so am completely new to this. Any help will be much appreciated.
Thanks

Hi,
I have created a package which uses the OLE DB Command as the target where I write the sql command to insert data into the table. The issue which I am facing is, while at the OLE DB COmmand , the package fails. I notices that it is not able to get the input columns which are mapped to the target columns.
The same package works fine when the target is on Oracle database or a SQL Server database.
For DB2, i have tried using the Microsoft OLE DB Driver for Db2, as the IBM DB2 Driver doesnt work for insert properly.
Any suggestion regarding this would be really helpful.
Thanks,
Manish

Hello!
I have created my self a person website in VS2008 using Linq and ahev downloaded a copy of sql express to use as my database when working on it at home.
I have just noticed, now I am trying to upload it to a server that my sql express is automatically creating the database in my app_data folder, this is causing me problems, as I don't want it to do this. I want it to be able to point it at a full version of SQL server.
Is there some setting I have missed? Of how can I stop tis automatic creation of the database?
Thanks
Bex

Hello,
Is there any ability to do database-level triggers in SQL 2000? I have a SQL 2000 database, and I was asked if we could create a trigger that whenever anyone touches the data in a database, to create an entry in an event log? If not, I have a main table I can put a trigger on; however, my question is how do you write to a file in a trigger as well?
Thanks.

Hi All,
I have seen some different behaviors when I am writing SQL Server compact edition Database file into SD Memory card or any user removable storage media.
The following Steps for reproducing these behaviors.
1. Set your database location is in the SD Memory card.
2. Create a database and establish session.
3. Writing first record into the database is done
4. Remove your SD card manually from the system
5. Try to write a Second record into the database
6. You will get the error from this "SqlCeWriteRecordProps" API call - This is fine.
7. Put your SD card back into the system.
8. Writing Second record again into the database is done - This is fine.
So far the behaviors are good after that
9. Remove your SD card manually from the system again
10. Try to write a Third record into the database
11. You will suppose to get the error from this "SqlCeWriteRecordProps" API call but you won€™t get that error €“ I don€™t know why?
12. Then Try to write a Forth record into the database
13. You won't get any error from the API call "SqlCeWriteRecordProps" and return status is success.
14. Now put your SD card back into the system.
15. Then write Fifth record but this time its writing record Third, Fourth and Fifth into the database.
Note:
I am clearing (means Free) my record structure everything after calling this function "SqlCeWriteRecordProps". So I don€™t know why its wring Third, fourth and fifth record into the database.
Please Let me know your feedback.
Thanks,
Rajendran

Is there a way I can write a query to dynamically select a database table. That is, instead of having a variable for a certain column like customerId which would be €œcustomerID = @customerID€? I want to use the variable to select the table. I assume I may have to use a stored procedure but I am unclear as to how this would be coded.
Thanks

Hey everyone I've got this question that has me stuck for the last few days but its an important part of my website.....What I am trying to do is basicly have a user be able to upload a file, have that uploaded file plus some other info automaticly display on other parts of my site, and have a different user eventually be able to download that file....I have thought about allowing the file upload as a BLOB but still cannot find a proper way to execute this using VB, plus I have heard that this way of doing it is not reccommeneded cause databases were not designed to store large files like this, lots of articles recommened having the file upload to a Folder on your server then get the binary data for the file that can be placed in a database to refrence that particular file.....Well this also proves to be a lot harder then said here is what I got so far (written in C#) protected void UploadBtn_Click(object sender, EventArgs e)
{
if (FileUpLoad1.HasFile)
{
FileUpLoad1.SaveAs(@"C:Documents and SettingsAdamMy DocumentsVisual Studio 2005ProjectsWebsiteFiles" + FileUpLoad1.FileName);
Label1.Text = "File Uploaded: " + FileUpLoad1.FileName;
}
else
{
Label1.Text = "No File Uploaded.";
}
}
and here is the asp part of the code that goes with it<asp:FileUpLoad id="FileUpLoad1" runat="server" />
<asp:Button id="UploadBtn" Text="Upload File" OnClick="UploadBtn_Click" runat="server" Width="105px" />
<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
Now from what I know is I need to get the binary of the file which I have read you can do with the Page.Request.Files statement but again not sure how I would impliment this. Does anyone have any suggestions on which way I should take when dealing with this should I try and just use the BLOB method or use the binary refrence method? and if so how would I impliment this, heck even some good tutorials on the subject would be great... Thanks.....Adam

let's say I have a table named "myTable" in a SQL database:
UniqueID
FirstName
FamilyName
1
Elizabeth
Moore
2
Chris
Lee
2
Robert
McDonald's
I want to create a SQL query should contain a parameter for example:
SELECT * FROM myTable WHERE UniqueID = @TextBox OR FirstName = @TextBox OR FamilyName = @TextBox,
and when I type in my TextBox the ' * ' character, it should retrieve the whole table...
hope anybody understood, will be happy to explain more.

Hello,
Is it possible to access both my database and the ASPNETDB within the same SQLDATASOURCE using SQL Express ?
I want to pull out some user details from the aspnet_* tables within the ASPNETDB
In my database I have created the 'UserId' fields so the relevant joins can take place.
In my web.config:
<connectionStrings>
<add name="mydb" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|mydb.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
</connectionStrings>
In my asp (showing only mydb):
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:mydb %>"
SelectCommand="SELECT [CreateDtTime], [UserId], [Comment] FROM [Log_Dtl] WHERE ([LogId] = @LogId)">
<SelectParameters>
<asp:QueryStringParameter Name="LogId" QueryStringField="LogId" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
Any help would be appreciated.
Thank you
Lee
