Hello,
You will have to look into making Owner-Drawn controls. There are many examples on the internet on how to do it. Searches such as "VB .Net Owner Drawn Control" in Google, ect, will help you in accomplishing your task. 
I hope this helps,

Hello!
My application is a text editor which uses plugins for each type of document.
I have written a COM server in C++ and I can write coclasses in C++ for each document type. I use COM component categorisation so my application can "find" at run-time, what document types are supported. Now I want to let a VB programmer write a COM object to represent a new document class but I cannot find if it is possible to write a VB COM object which can use COM categorisation.
Can I write a COM component in VB which can have a COM category or can I only do this in C++?
Is there a definitive list of limitations in VB vs C++ for COM development?
Can anyone help with this?
Thank you

Is there an easy way to set a datagrid for Windows forms to select by row ?
|
|
|
|
|
Hi,
Try this code.
Private Sub myDataGrid_CurrentCellChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles myDataGrid.CurrentCellChanged
myDataGrid.Select(myDataGrid.CurrentRowIndex)
End Sub

Thanks ! That works great.
I still have one question though. I can now select by row but
the datagrid still sets a cursor on the current cell in that row.
I've put the setting "allowedit" to false but this doesn't prevent
that you can select the text in a cell (for copying, etc.)
Also when I want to scroll through my data, it just scrolls a couple
of lines and then stops.
Can anyone help me out with this ?

Why does everyone what to do a "Messenger" program first? You should learn to walk before you can run. Seriously - there is a heck of a lot to consider in a messenger type application. You have a client application and a server application (unless you are going p2p in which case you need some sort of "discovery" mechanism). You have to register users within the system and manages and so on and so forth.
Sorry that this doesn't seem to be a helpful reply to you, but there is a lot going on in an application like that and it would take far too long to explain in a forum post to someone who has "just started [their] first program"

Is this your first program in any language? If so, your taking on a HUGE project for such a beginner.

Does anyone know how I might be able to have a VB.Net program automatically recognize that a USB drive has been plugged into a computer. File watcher is the only way I can think of but I was wondering if anyone might know of another way.

Ignore the Demo folder in the zip
the one you want is the DeviceChangeNotify folder.

Hello,
The code to remove an item from a combobox at runtime is:
ComboBox1.Items.RemoveAt(ComboBox1.SelectedIndex)
I hope this helps,
