DirectShow. If you'd googled it, you'd probably have found pages with links to download it, as well.

Hi,
How to Auto fit the column width of data grid depending upon the number of characters in a cell of a row?How to get the pixel width of column ? I want to know if each characters will have different pixel size.
Ex Empname="SARESH". How many pixels this data will take? Here the empname will change dynamically depending upon the data fetched from the query.
Waiting for an early response.
Thanks
Riz

The MeasureString function of the Graphics class might provide some help.

As an aside, since you are using .Net and assuming this is a desktop app, the DataGridView control has AutoSizeColumnsMode and AutoSizeRowsMode properties in the Layout section which you can tweak to get the desired result.

Thanks for ur response
I think u r talking abt Visual Studio .Net 2005. I am using 2003 Version. So my datagrid does not have any AutoSizeColumnsMode and AutoSizeRowsMode properties in the Layout section. And yes it is a Windows Application.
Can u sugest me any other solution to this problem.
Regards,
Riz

I am populate a combobox when they type each letter, so as they type a each letter words that apply to each letter is populated in the combobox, but I am having a problem when I clears it while they are typing it starts back at the begining so instead of them typing "abc" it goes "cba". Does anyone know how to make it so it doesn't do that?
Here is sample of my Code:
Title = ComboBox1.Text
FileOpen(1, "/Titles.txt", 1)
ComboBox1.Update()
ComboBox1.Items.Clear()
Do While Not EOF(1)
Input(1, Titles)
If Title.ToUpper = Mid(Titles.ToUpper, 1, Titles.Length) Then
ComboBox1.BeginUpdate()
ComboBox1.Items.Add(Titles)
ComboBox1.EndUpdate()
A = True
End If
Loop
FileClose(1)

Sorry, but I'm not to sure what the problem is. But here's how you add text to the ComboBox, and then remove it (if that's what you need).
'Add text
ComboBox1.Items.Add(TextBox1.Text)
'Remove text
ComboBox1.Items.Clear()
Hope this is what you needed.
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

Perhaps set the combobox to sort the list, i thinke the property is sorted = true. If that doesn't work, clear and repopulate the list from the original source.

Hello,
In my form frm1, I display certain information from a query in a datagrid. I have set up a hittest to allow the user to click the first column of any record, which would then open frm2, which would display all of the details for the selected record. I set up a variable on frm2, so it's ready to receive the information I pass it. The problem is, I can't figure out how to pass it the needed information, which would be the data in one of the columns of the selected cell. Here's the code:
Private Sub dbgStock_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dbgStock.MouseDown<br />
<br />
Dim pt = New Point(e.X, e.Y)<br />
<br />
Dim hti As DataGrid.HitTestInfo = dbgStock.HitTest(pt)<br />
<br />
If hti.Type = DataGrid.HitTestType.Cell Then<br />
<br />
If hti.Column = 0 Then<br />
Dim frmDetails As New frmDetail<br />
frmDetails.ID = "no idea what I need to put here"<br />
<br />
End If<br />
<br />
End If
What code should I insert for frmDetails.ID?
Any help would be appreciated. Mike

I am sorry if this is a redundant question. I have searched messages in the SQL and Visual Basic .net message boards and have not seen complete code example for setting up connections before executing a query which joins two(or more) tables and each table exists in a different database but on the same server.
I am aware of the naming convention ServerName.DatabaseName.TableName.Column
I am aware of populating datasets in vb.net as exemplified below
-------------- Begin populate dataset example -----------------------
Dim DataSetForReport As New DataSet
Dim BlueConnection As String
Dim BlueSQLConn As SqlConnection
Dim BlueQuery As String
Dim i, TotalRowsReturned As Integer
BlueConnection= "uid=test;password=snow;dtabase=DataBaseBlue; server=Spock"
BlueSQLConn = New SqlConnection(BlueConnection)
BlueSQLConn .Open()
BlueQuery = "Select Table1.ColumnA, Table2.ColumnB from Table1, Table2 where ColumnA=ColumnB"
Dim SqlDataAdapterForPopulateDataTable As New SqlDataAdapter(BlueQuery, BlueConnection)
i = SqlDataAdapterForPopulateDataTable.Fill(DataSetForReport, "TableOfData")
SqlDataAdapterForPopulateDataTable.Dispose()
SQLConn.Close()
If i > 0 Then
'query returned at least one row
TotalRowsReturned = i
End If
-------------- End populate dataset example -----------------------
Goal: to be able to change BlueQuery variable to refer to two different databases - DataBaseBlue and DataBaseRed like something below...
BlueQuery = "Select DatabaseBlue.Table1.ColumnA, DatabaseRed.Table2.ColumnB from DatabaseBlue.Table1, DatabaseRed.Table2
where DatabaseBlue.Table1.ColumnA=DatabaseRed.Table2.ColumnB"
If I create another connection like
RedConnection = "uid=Red; password=Car; dtabase=DataBaseRed; server=Spock"
and use it in an addition SQLConnection declaration
Dim RedSQLConn As SqlConnection
RedSQLConn = New SqlConnection(RedConnection)
RedSQLConn.Open()
How do I enable/pass SqlDataAdapterForPopulateDataTable variable two different connections? Or how do I accomplish the "Goal" in another way?
Thanks for any suggestions.

You can't change the query to work on two different databases at the same time.
In theory, you can probably get data from two different databases into the same DataSet using two seperate connections and queries. Just make sure the data ends up in two different DataTables in the DataSet. You should be able to put together a DataRelation object that joins the two tables, do your work on it, then use two the two different DataAdapters and their connections to write those two tables back to the databases if you've made any changes.
Sorry, I don't have any examples. I've never done it myself. You can find the docs on DataRelation here[^].

Dave,
Thanks for taking the time to share your thoughts. I was trying to avoid two separate datatables but if that is the only way, then that is the only way.
I know there are good/great technical people at Microsoft. However, I would think this is a common enough situation that a method/tool/wrapper would have been added to be able to handle a single query referencing two or more tables in two different SQL Server databases. My two cents.....

It may be possible to do with a stored procedure, but not with any code on the client side that I know of. You might want to post the question in the SQL Forum[^]. There's a guy in there, Colin Angus Mackay, who knows FAR more about SQL Server than I do.

Hi folks!
I am trying to create an Excel-like table layout.
Currently, I am using TableLayoutPanel. However, this control has its limitation, like I can't draw thicker border in certain cell.
Is there better way to create this Excel-like table layout?
Many many thanks in advanced!!!

Is this a web app or Windows ?
I'd start with the gridview, it has a lot of stuff built in already

This is a Windows form using Visual Basic 2005.
Isn't GridView for data that is pulled from a database?
My data doesn't come from a database.
Thanks!

No, a grid view knows how to show data from any source.

I tried using GridView. It doesn't seem like my purpose.
I am using the TableLayoutPanel is for LAYOUT purpose. Inside the TableLayoutPanel, I put some controls.
Also, GridView draw thicker border in certain cell, right?
It seems like GridView is more to data-presentation while what I am trying to achieve is Layout Presentation.
Thanks Christian for your guide so far!

Why?? It's a dead language. I highly suggest switching to VB.NET. You can get a free version of it here[^].

I recommend buying a book or learning to use google ( probably both ). You're asking Dave to write your program for you, when it's very simple, and widely documented. These forums are for help, not for people to write your code for you, or even to explain exactly how to write it all.
