VS 2008 Setting Focus To An External Textbox?

Mar 26, 2010

Essentially what I would like to do is press a button, this then triggers a code to focus on a certain program, focus on a certain textbox and input the text from the clipboard not via pasting.

Now I have been able to achieve all of the above fairly easily except for one crucial component, focusing on the desired component. This program is essentially to automate some data entering for users via hotkeys, therefore I can't simply simulate tabs as it will not always be in the same position. So now comes the question, how do I focus on specific textboxes/controls in other programs?

I've been able to find huge walls of code with no explanation beyond "this is a concept". However no documentation or relevant examples.

C# - Setting External Application Focus?

Dec 17, 2009

In VB.NET, you can set focus to an external application using

AppActivate("Windows Name")


AppActivate(processID As Integer)

Now this works fine if you do for example:

Dim intNotePad As Integer = Shell("C:WINNTNotepad.exe",

But when I do:

For Each theprocess As Process In processlist
If InStr(theprocess.ProcessName, "DWG") Then
strProcessList += String.Format("Process: {0} ID: {1}", theprocess.ProcessName, theprocess.Id) + vbCrLf


then it doesn't find the window, even if it's open and even if it finds the window using the window title.But I need it by process ID.How can I do that?I need it to set focus on a 3rd party installer in a windows installer setup project.

VS 2010 - Setting Position Of External Application?

Sep 7, 2010

I'm trying to set hotkeys for all my favorite websites. When one of these hotkeys are pressed, I want it to load the assigned website in internet explorer, but I want internet explorer to load on my SECONDARY monitor. I've already set out the hotkeys to load internet explorer, but it loads on the wrong screen. How to check if an instance of IE is already running. To be a bit more specific: the secondary monitor is set to the LEFT of the primary one. And the resolution is at 1440 x 900. So basically, I want to programmatically set IE's position to (-1440, 0) from within my application itself.

Setting Focus In A DataGridView's Cell?

Mar 16, 2010

I am trying to set the focus in a datagridview's cell after the user enters some data and tries to tab out of the cell. I can't seem to get the focus in the cell they just edited. I can change the background color, but the focus goes to the next field in the grid. I am trying to do this in the _CellValidating event. Here is my code :
