Question related to Visual Basic Video Lesson 09 (Databinding.wmv) by Bob Tabor.
Made a table and a UI form according to this lesson (table colums: CustomerID, FirstName, LastName).
Is it possible to use the same or an identical looking query form to find "Bob" by typing Bob in the Fist Name textbox or "Tabor" by typing Tabor in the Last Name textbox as in FileMaker?
Thanks,
(Hope this isn't a "stupid" question, but I haven't been able to find a straight-forward answer anywhere)"
I currently have code that iterates through a dataview's records, making a change to a field in some of the records. The way I have this coded, a conection has to opened & closed for each individual record that's updated:
dsrcUserIae.UpdateCommand = "UPDATE UserIAE SET blnCorrect = @blnCorrect WHERE (ID = @ID)" dsrcUserIae.UpdateParameters.Add("blnCorrect", SqlDbType.Bit) dsrcUserIae.UpdateParameters.Add("ID", SqlDbType.Int)
Dim myDataView As DataView = CType(dsrcUserIae.Select(DataSourceSelectArguments.Empty), DataView) For Each myRow As DataRowView In myDataView If myRow("FkUsersAnswerID") = myRow("AnswerID") Then intCorrect = 1 Else intCorrect = 0 End If dsrcUserIae.UpdateParameters.Item("blnCorrect").DefaultValue = intCorrect dsrcUserIae.UpdateParameters.Item("ID").DefaultValue = myRow("ID") intUpdateResult = dsrcUserIae.Update() Next
It seems like I should be able to do something like this (call update once), but I'm not sure how...
dsrcUserIae.UpdateCommand = "UPDATE UserIAE SET blnCorrect = @blnCorrect WHERE (ID = @ID)" dsrcUserIae.UpdateParameters.Add("blnCorrect", SqlDbType.Bit) dsrcUserIae.UpdateParameters.Add("ID", SqlDbType.Int)
Dim myDataView As DataView = CType(dsrcUserIae.Select(DataSourceSelectArguments.Empty), DataView) For Each myRow As DataRowView In myDataView If myRow("FkUsersAnswerID") = myRow("AnswerID") Then myRow("blnCorrect") = 1 Else myRow("blnCorrect") = False End If Next
intUpdateResult = dsrcUserIae.Update() 'Want all changed myRow("blnCorrect") to be updated to datasource
Can anybody explain how to do the bulk update? I've seen some info about AcceptChanges and Merge, but I'm not sure if they apply here, or if they more for Transactions.
Hi,
I got a problem.
I installed Microsoft SQL Server Management Studio Express 2005 version.
And I created a Compact database.
I created an connection in SSMSE to connect the database and opened a query form.
then, i run the following sql:
Select * from Table1
It returned 3 records to me.
After that, I used program to insert record into this table.
Then i ran this sql again, it still show me 3 records.
I closed the query form, and re-created a new query form, then run the sql, it returned 4 records to me.
Why? It's very strange and difficult to operate, right?
Is there anyone know how to make the SSMSE to return whole records without any close query form and re-create query form operation?
Thanks a lot!
And Merry X'max!!!
Hello,
My company Intranet has a form that agents can use to post their comments about the company to upper management, but our customer service department would like to modify the form so that the agent has to pick from a comment type.
The dropdown options on the form will be as follows:
ComplimentsComplaintsGeneral CommentsSuggestions
Each dropdown option has a designated table in a SQL DB.Using postback on the same page, I need to change which fields of the form are visible based upon which dropdown selection the user chooses, and I need the fields to then be inserted into the table that corresponds with the dropdown selection item.
For example: If the Compliments dropdown selection is picked, I need a text box to show for the user's location, the name of the customer, account number, and the message box. Once the submit button is clicked, the characters in these boxes need to be inserted into the Compliments table using its data adapter.
However, if the user selects Suggestions, the name of the customer and the account number should not be visible, since these fields do not exist and when the submit button is pressed, the Suggestions table should be updated.
If you need more information, I will provide whatever is needed.
As always, thanks for everyone's assistance.

View 1 Replies View RelatedI'm very new to asp.net and c#, I have been thrown in the deep end with a project at work and I'm really struggling to overcome this problem so any help will be very greatly appreciated. I have a form with a number of textboxes that users use to update records in a database table with the use of a stored procedure. The problem is that I can't get the form to just update the boxes that a user has filled out. The form is working at the moment only if the user fills out all the boxes on the form which obviously is a waste of time if they only want to update one field. I have tested the stored procedure and it works fine. Please find the below code I'm trying to use!

I have a Table which stores data from two different databases. To update it I made a Web Form that opens a single record where you can edit the data (using TextBox). Then there is an Update Button, which is supoused to Update that record in the SQL Database. However, for some reason it does not work. I get no error and every thing seems to work fine, but the data is not updated. When running the same UPDATE statment in the SQL Query Analyzer everything works just fine. Here is the code for the button click (For test purpose I've set a spesific record to update the Task cell to "Test" and I've adde a DataGrid to be able to see if something is happening):
Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click
Dim objConnection As SqlConnection
Dim objDataAdapter As SqlDataAdapter
Dim objDataSet As DataSet
Dim objDataView As DataView
Dim strConnect As String
Dim strSQL As String
Dim strUpdate As String
strConnect = "Persist Security Info=False;Integrated Security=SSPI;server=SRV01;database=DB1"
strSQL = "SELECT * FROM Users WHERE UserID ='" & Request.QueryString("UserID") & "'"
strUpdate = "UPDATE Users SET Task = 'Test' WHERE UserID = 36" '" & Request.QueryString("UserID") & "'"
objConnection = New SqlConnection(strConnect)
objDataAdapter = New SqlDataAdapter(strSQL, objConnection)
objDataAdapter.UpdateCommand = New SqlCommand(strUpdate)
objDataSet = New DataSet
objDataAdapter.Fill(objDataSet, "User")
objDataView = New DataView(objDataSet.Tables("User"))
dgrTest.DataSource = objDataView
dgrTest.DataBind()
objDataAdapter.ContinueUpdateOnError = True
Try
objDataAdapter.Update(objDataSet, "User")

Bear with me plase as I am nto very familiar with the coding world. The project I am working on is giving me troubles. I am trying to set up a form that can be used on line for our sales staff. It is a call activity form that I was hoping to submit to the DB I Have created in SQL. I would like the sales staff to fill out this form and then have their information transferred to the DB so that I can generate reports from that data. The trouble I am having is getting the intial connection to the DB opened up using the submit button on the form. I go into the code behind the page, and I have entered many scripts with no success. I continue to see that I receive erros when I try to use the opening line:
Dim cn As New ADODB.Connection
If anyone out there has some sample scripting that would help me with this, I would really appreciate it. Thank you.

I've a weird problem in my application. In of the pages, while trying to update the text box "Name", when I enter Linda's test, it gets saved as Linda''s test. I'm not sure if this is a problem due to SQL server. When I look at the stored procedure, I don't anything different. Also, when I update the table directly in SQL Server, the result is displayed in single quote. But if I update the field thro' the application, the returned name is with double quotes instead of single quote. Has any of you faced problems like this? What am I missing? What do I need to do to get the name saved the way I entered (with single quotes) instead of double quotes?

I have two tables. The table is below.
Table name 1 : Income
Income RentMonth
1500 Jan
1500 Feb
1500 Apr
Table name 2 : Expense
Expense ExpMonth
200 Jan
300 Mar
400 Apr
The result table becomes (Profit=Income-Expense)
Profit Month
1300 Jan
1500 Feb
-300 Mar
1100 Apr
But I form the query by join the both Income and Expense tables to subtract the Income and Expense month wise.
But one moth is in one table the same month is not in another table.
For Example Feb month is in Income table, but not in Expense table.And Mar month is in Expense table and not in Income table. So how will I form the query to achieve my result table as i indicated above. Kindly help me.

Hello,
I am using a sqldatareader to get back a whole set of data.
The columns are id, data_id and data_desc
for example, the collection is id data_id data_desc0 100 this is name for id 00 101 this is address for id 00 102 this is gender for id 01 100 this is name for id 11 101 this is address for id 11 102 this is gender for id 12 100 this is name for id 22 101 this is address for id 22 102 this is gender for id 23 100 this is name for id 33 101 this is address for id 33 102 this is gender for id 3
I want to be able to go thru' this list and break up for each id and create a txt file. So, i will have four text files.
txt0.txt will contain100, this is name for id 0 101, this is address for id 0102, this is gender for id 0
I would like to know, how do i use a dataview to break up the sqldatareader so i can then repeat the loop for each id and generate the text file.
I don't have a problem generating the text file.
Please let me know, how should i go about it.
Thanks a bunch,-Sean
I don't know if this topic should go in this forum category or in the SQLDataSource forum.
I need to be able to provide SQL which varies based on what the user enters on a page. However, this isn't as simple a providing parameters in the SQLDataSource control because the SQL changes depending on what the user selects. For example, in a customer search page, they choose to search by either first name or last name from a drop down list and then enter the name to search for in a text box. The dataview should display the matching customers.
How can I set this SQL based on the entered values while also keeping the paging and sorting capabilities of the dataview? You don't seem to be able to set the SQL for an SQLDataSource at run time.
I have an ASP form that takes the information that is entered on the form and inserts it into a Microsoft Access database. It works great. In addition to the fields from the form, I also want to add the current date into the InitDate field. How would I modify the SQL query below to insert the current date into the COS database? conn.execute SqlQry Sql = "INSERT INTO COS ([Name of School], [Director of COS], [Address], [City], [State], [zip], [PhoneNumber], " Sql = Sql & "[general_notes], [type], [DEPT], ) "
Sql = Sql & "VALUES ('" & m_CompanySchoolName & "',
'" & m_FullName & "', '" & m_StreetAddress & "', '"
& m_City Sql = Sql & "', '" & m_State &
"', '" & m_Zip & "', '" & m_TelephoneNumber & "', '"
& m_Message & "', 'COSMETOLOGY', '" Sql = Sql & m_Department & "', '" & m_EmailAddress & "')" response.write Sql response.end conn.execute Sql

I am trying to run a UNION ALL query in SQL SERVER 2014 on multiple large CSV files - the result of which i want to get into a table in SQL Server. below is the query which works in MSAccess but not on SQL Server 2014:
SELECT * INTO tbl_ALLCOMBINED FROM OPENROWSET
(
'Microsoft.JET.OLEDB.4.0' , 'Text;Database=D:DownloadsCSV;HDR=YES',
'SELECT t.*, (substring(t.[week],3,4))*1 as iYEAR,
''SPAIN'' as [sCOUNTRY], ''EURO'' as [sCHAR],
[Code] ....
What i need is:
1] to create the resultant tbl_ALLCOMBINED table
2] transform this table using PIVOT command with following transformation as shown below:
PAGEFIELD: set on Level = 'Item'
COLUMNFIELD: Sale_Week (showing 1 to 52 numbers for columns)
ROWFIELD: sCOUNTRY, sCHAR, CATEGORY, MANUFACTURER, BRAND, DESCRIPTION, EAN (in this order)
DATAFIELD: 'Sale Value with Innovation'
3] Can the transformed form show columnfields >255 columns i.e. if i want to show all KPI values in datafield?
P.S: the CSV's contain the same number of columns and datatype but the columns are >100, so i dont think it will be feasible to use a stored proc to create a table specifying that number of columns.
I am creating an ad-hoc reporting module for my website. The user may select a list of columns and specify the WHERE for the report. I build the select statement and the where statement and pass the info to a stored procedure. The stored procedure accepts 3 select parameters and a 3 wherestmt parameters. I finally got the SQLDatasource to work by setting the parameter values in the Selecting method of the SQLDatasource. Binding it to a gridview shows me all my values. Now, I am trying to programmatically call the select method of the SQLDatasource so I can get a dataview or datareader to manipulate further. I am getting an null back when I call the select method. Any ideas why? or a workaround?

Hi,
I use a filter on a dataview which has uniq rows. I need to bind several fields of the result filtered row to textboxes. Here the code :
protected void Page_Load(object sender, EventArgs e) { string id = Request.QueryString["id"];
if (PreviousPage != null) { SqlDataSource dsPrev = (SqlDataSource)PreviousPage.FindControl("SqlDataSource1");
DataView dv = (DataView)(dsPrev.Select(DataSourceSelectArguments.Empty)); dv.RowFilter = "dr_id='" + id + "' "; dv.RowStateFilter = DataViewRowState.CurrentRows;
txtFirstName.Text = // ??? FirstName Field
txtLastName.Text= // ??? LastName Field
txtAddress.Text= // ??? Address Field } }
I don't know which cod to put in those lines.
On the help of the dataView there is an example that use DataBindings. This example is in the DataView.RowFilter article:
Text1.DataBindings.Add("Text",view,"CompanyName");
The big problem is that I don't have a method or event call 'DataBindings'. I just have 'DataBind' method or dataBinding event and they both don't support the 'Add' method.
So how can I bound those controls to my filtered Dataview field value.
Thanks,
David

Hi,
I am using Visual Studio 2005. I am trying to create a ASP.net website and use a web form to get the results of an enquiry. It is almost the same as the presentation video on this website called "How to Create Data Driven Website", but I have added a new twist to it. I want to use the "LIKE" instead of "=" in my SQL statement and I want to use wild cards in the parameter value that I enter.
<form id="form1" runat="server"> <div> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<% dim str as string = "%" & textbox1.text & "%" </%> <asp:TextBox ID="TextBox2" runat="server" Visible="False" Text=str></asp:TextBox> <asp:Button ID="Button1" runat="server" Text="Submit" Width="87px" BackColor="Khaki" ForeColor="Navy" PostBackUrl="~/Default.aspx" />
and the ControlID of the Datagrid will take in the value of "TextBox2" instead of "TextBox1" as so:
<SelectParameters> <asp:ControlParameter ControlID="TextBox2" DefaultValue="SO06000001" Name="SO" PropertyName="Text" Type="String" />
However the syntax above does not work. May I ask what is the correct syntax?
Thanks.

I'm trying to look up customer records by e-mail domain by using a text box on a Web form. So if I want to look for all my customers that have an aol e-mail domain, I would type aol.com in the text box and the sub routine would know to count 7 characters from the right and through those characters into maybe a parameter query. I'm having problems passing this in. I can count the characters properly by using:
dim strText = MyTextBox.Textdim intLength = strText.Length
but having problems starting here......
MyCommand.SelectCommand.Parameters("@email").Value = MyTextBox.Text
..............
but how would I ultimately feed this into my sql satement? Select * from Customers Where email = right(@email,intLength)
Help appreciated.

Frustration has gotten the best of me on this one. Can anyone help?
I need to pass the current value in an Access Data Project (back-end is MS SQL) text field to the where condition in an SQL using VBA. This is what I have, but does not work.
Private Sub Command44_Click()
Me.SS.SetFocus
Dim strSQL As String
Dim strSSecurity As String
strSSecurity = Me.SS
strSQL = "Update Employees Set employees.PositionID = '',employees.jobcode = '' Where employees.ss = strSSecurity"
DoCmd.RunSQL strSQL
End Sub
It is supposed to take the current Social Security number from the form and match it against the employees table. Once it finds the matching record it should update the PositionID and JobCode fields to '' (empty string)
But it doesn't
Anyone with any ideas?
Thanks

Hi,
I am a newbie, this is my first post (please go easy).
Iam at the moment trying to set up a query for someone looking for a property on an estate agents website.
From a drop down menu, the user can:
select an area (where they may like to live) from a list of areas.
select an amount of bedrooms from a list of bedrooms
select a minimum price from a list of prices
select a maximum price from a list of prices.
The query I worked out for this is as follows:
$data = mysql_query("SELECT * FROM property WHERE area like '$area' and bedrooms like '$bedrooms' AND price BETWEEN '$min_price' AND '$max_price'") or die(mysql_error());
This seems to work fine and shows all the properties that meet the criteria onto my webpage.
However, I then thought, someone may not care which area they live in and want to see all properties in all the areas, so I decided to add the option 'All areas' to my 'areas' list, I then did the same for the other lists, eg 'all bedrooms' option to my bedrooms list and so on.
I am now trying to write a query that incorporates where the 'all..' option is selected and have become very stuck!
Can someone set me off in the right direction for this.
I hope that makes sense?!?!

I have the following SqlDataSource in my page:<asp:SqlDataSource ID="sqlds" runat="server" ConnectionString="<%$ ConnectionStrings:cs %>" SelectCommand="SELECT [Quest1], [Quest2], [Quest3], [Quest4], [Quest5] WHERE ([QuestID] = @QuestID)"> <SelectParameters> <asp:Parameter Name="QuestID" /> </SelectParameters> In my code I get the following error: "Cannot convert type 'int' to 'System.Data.DataView'", I don't understand why I am getting this error because I am casting my SqlDataSource as type DataView when passing it to my DataView type.Code: protected void Chart(string record) { System.Data.DataView dv = (System.Data.DataView)sqlds.SelectParameters.Add("QuestID", System.TypeCode.Int32, record); //Error line ... ... ...}If anyone could point me in the right direction I would be very grateful.
