how to access dynamically created control - Visual Basic Discussion Boards

1) place a shortcut to your app in the start menu/programs/startup folder

2) do research on System.Windows.Forms.NotifyIcon

in the forms' closing event

Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
e.cancel=true
me.hide
turn on the notifyicon object
End Sub

Hi How can I display row numbers on the left hand side of a datagridview control. (i.e. not in the cells)

hi RichardBerry,

try following code

Dim i As Integer
For i = 0 To datagridview1.Rows.Count - 1
datagridview1.Rows(i).HeaderCell.Value = CStr(datagridview1.Rows(i).HeaderCell.RowIndex + 1)
Next

hope this helps

Hi Rupesh

Thanks, that does work

I was however hoping for somthing automatic. Also if I delete a row, then I will have to catch that event and renumber the rows.

Thanks for your help though Smile | :)

hi all,

I dynamically create buttons on main_form, then in a module (functions) i try to access this controls by setting an focus to one of them.
when i try to access with "index = Frm_Main.CtrlFocus" it doesnt work becouse number of controls is zero since this frm_main is new instance i guess?!

Does anyone know how to fix this, and if there is a better way?

Thanks
greg

My website

I have created one application in VB.Net.
I want to create one shortcut for it
like Window key+E (for Explorer).
How can i do that?

I'll need some clarification.

Are you looking for a shortcut like from you own desktop or are you looking for how to create a shortcut to your application from within a distribution set? So as to automatically create a shortcut on a users PC desktop when installing your app.

Jelle

automatically create a shortcut on a users PC desktop when installing app.

You will need to use Win32 API.

here are functions you can use...

<br />
 [DllImport("USER32.dll")]<br />
 public static extern bool RegisterHotKey(IntPtr hWnd,<br />
          int id, int fsModifiers, int vlc);<br />
<br />
 [DllImport("USER32.dll")]<br />
 public static extern bool UnregisterHotKey(IntPtr hWnd, int id);<br />

"If our Mind can, the Program can !!"

Are you going to check whether the user is using that shortcut for something else first? Hijacking users' control over their own machines is not a way to create good will towards your app.

Hi,
Currently I am designing a tool in VB.Net for automation of a datawarehousing tool called DataStage. I have to run this tool through command prompt in VB.Net. The command is

dsjobs –server xx.xxx.xx.xx –user abcd –password wxyz –run
[Project] [Job] [List of parameters]

Application path is the location where datastage client is installed in the local machine.

Other attributes like:

-lparam: Give the list of parameters for a particular job
-ljobs: List all the jobs in a particular project
-lprojects: List all the projects available in the server
-run: To run a job
-stop: To stop a job etc….

Now can anyone help me how to put these in VB.Net and how to fetch the results of these commands. Because based on the results of these commands I have to create dynamic text boxes.
It looks complicated, but can anyone who knows this help me out ?

Thanks in advance.

Process.Start is basically shellexecute, you can pass your parameters through there.

What is the best way to make my program in several languages? Should I create text files that contain label text, window titles, messagebox texts in different langugaes or what do you recommend?

Store all your strings in the application resources and ship different resource files.

I a bit of a beginner. How do you do this in practice? Could you give me an example? Let's say label1.Text is in Finnish "Jotain" and in English "Something".

That is how I would do it, except I would use an Ini file. Using an Ini file would make the process of organizing text between controls and dialogs a lot easier.

Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

OK, I have never used INI files. Could you give me some practical example or reference in web? Thanks?
