I've populated my DataGridView in which first column in a checkbox(System.Boolean) column. I want to select rows if a checkbox cell is clicked causes the Checkbox.Checked to true.
Private Sub gd1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles gd1.CellClick
If e.ColumnIndex = 0 Then
Me.gdFeePlan.Rows(e.RowIndex).Selected = Me.gd1.CurrentCell.Value
End If
End Sub
gd1 is the DataGridView
and column(0) is checkboxcolumn
Above code doen't works. When I select a row in Grid. I want to select all rows which holds first Checkbox Column Checked to true.
Can you help me?

I tried this the other day. I now have more information that I did not have before.
I have a DLL called spoem.dll
I Have a LIB called spoem.lib
In C++ there are the lines:
#define SPOEM_API __declspec(dllimport)
#pragma message("automatic link to spoem.lib") // <== add this line
#pragma comment(lib, "spoem.lib")
This last line I guess calls a linker the the LIB file. My understanding is that
the DLL has no entry points. Each function in C gets linked intot he program calling
this line.
#pragma comment(lib, "spoem.lib")
Is there any way in VB.NET to mimic this same behavior . I need to link
this LIB file into my VB.NET project.
Thanks

No, there isn't. A lib file is used during the linking of the C++ object files to get an .EXE. The lib files can ONLY be used with C/C++. They're of absolutely no use to your VB/VB.NET code. You can only use the .DLL version calling the functions it exposes.

That's not what I said. I said the .LIB file was useless. I didn't say the .DLL couldn't be used. The problem with the entry points is because the name you're using doesn't match the name in the .DLL. You can see the function exports if you open the .DLL in the Dependancy Walker utility. You can find it at http://www.dependencywalker.com/[^]

Buy a book. No-one can answer your question, you have not asked one. If you have specific questions, ask them. If you're totally lost, buy a book and learn the basics.

Hello,
Can anyone please help me. I am new to VB.Net. I want to do a program that lists all the comm ports and the device name if any connected to those ports. For eg. we have a credit card reader connected to a port and it shoud display Comm1 : Moneris Credit Card Device. This is to help users to setup their initial settings for the program.
Thanks

There's no way to ID the device attached to the port. There was never a specification to identify serial devices. You can TRY certain commands that you know the device will respond to, and how it will respond, but most devices won't just plain old tell you "I'm a whatever" with a single well-known command. It just doesn't work that way.

Could someone help me? I am trying to pass optional dates via a function.
I have VB.Net 2003.
What am I doing wrong? I keep getting asquibbly line under the zeros.
Here is a sample of the code.
Public Function myFunction(ByVal sSQL As String, Optional ByVal dToDate As Date = 0, Optional ByVal dFromDate As Date = 0) As Boolean
|
|
|
|
|
My first gut reaction is that 0 is not a valid date. I would try putting a valid date in. I would try something like #3/28/2007#
Hope that helps.

Like kubben said, for Optional Paramaters you need a default value and 0 (Zero) isnt a valid date value

You need first to get a count of the files and folders you're going to delete, then you just increment the progress bar after every delete call. Directory.GetFiles will give you a string array of files without that DirectoryInfo stuff. File.Delete will delete them. You should store the paths as you're counting them, so you don't need to get them twice.
It would work better to use a BackgroundWorker to do the deleting, and call it's ProgressUpdated event to update your UI, but calling Application.DoEvents() whenever you update the progress is easier and should work fine.

I'm really stuck on this one.
I've got an mdi parent (with a single menustrip) + one mdi child (with no menu strips).
When I maximize the mdi child, it separates the mdi parent title bar and mdi parent menu bar, inserting a new line between them containing only the child icon and child control box.
Even stranger, when I close the app while a child is maximized, it distorts the size and location of the mdi parent (saved in My.Settings) by the height of this new "strip". So, repeatedly opening and closing the app with a child maximized causes the mdi parent to "creep" - the height decrements by the height of this mysterious "strip."
I have a tiny sample app to demonstrate the problem.
Can anyone help me out of this?
(I'm using VS 2005, vb.net 2.0)
Thanks.
Pat
