VB Sending Keystrokes To A Minimized Window/app?
Apr 26, 2012
im a complet noob in vb . i have been trying to figure out how to send keystrokes back to my own application , while minimized/ Or focused on an other window.i think i need to use PostMessageA . i read about it on forums. But its like chinese for me.my goal is to run these little programs by the 100's on 1 pc. and they just press a key in their own application , over and over.i was thinking something like this
Private Declare Function PostMessage Lib "user32.dll" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private Const WM_CHAR As Long = &H102
PostMessage("notepad", WM_CHAR, "T", 1)

I know how to send mouse clicks and keystrokes into an application when it is open and active, but this particular application the task is very repetitive and can be done with a script of sorts. What i want is how do i make a program to be able to send inputs (key clicks) into the application when it is minimized (the application minimized that is). doing this minimized would then allow me to do other more important things whilst the vb program is sending instructions into the other app.[code]...

I'm trying to do some interface for a game for people with mobility probs, like Parkinson, so grouping several game features in just one control.Everything goes fine but having problems sending keystrokes to the game window when they have modifiers.Lets say I want to send Alt+F1 keys, according all the search I have done, the code is:My.Computer.Keyboard.SendKeys("%{F1}")but it does just like I sent an F1 Keystroke: My.Computer.Keyboard.SendKeys("{F1}").I need to send Function Keys alone and too with Alt and Ctrl modifiers, but not success with modifiers, the game only gets like an alone function Key was pressed.

My form contains a Button and a Flash Control. The Flash Control contains a game referenced to a website. I want to send keystrokes into that control (the game) without having to be in focus. I'm not experienced in flash so when I decompiled the game, I had no idea how to script a way for it to work programatically.

I have a VB.NET application that uses Managed DirectSound to capture audio.Everything works just fine until (a) the application is minimized or (b) the application is completey obstructed (covered) by another window.
The thing is that the CaptureBufferDescription structure does not include a GlobalFocus property so I don't know what to do to let my application continue capturing when the main window is hidden.
Here's the basic initialization code I'm using:
' Create a buffer description object
bufCapDesc = New CaptureBufferDescription()
With bufCapDesc

How do I make the form send keystrokes such as Tab, Enter, Left Arrow etc to itself without interfering with other programs? If I use the SendKeys.Send method, it would send it to whatever window is opened. Is there a way to only work with the form? Very quick random example: Let's say I have 5 textBoxs and I click the 'Tab' button 5 times. What would happen ?
It would change the focus from one textbox to another right? Can I make this happen automatically ... like make it happen in the background and only to the form itself. So If I'm typing something on Notepad, I don't want to receive those 5 tabs. By the way I know I can use this code to change the fofucs, but remember its only an example.

In Visual Basic 2008 Express Edition, how would I send keystrokes to a specific window. Right now, I just keep the window I want on top and use sendkeys.send("{enter}"). The window that I want to send keystrokes to is my applications window.

I'm trying to send the keys "ABC" and "Enter" to Notepad when I press a button. I've been reading forever on Hooks, "SendKeys" functions, but I can't figure it out. I don't think I need to use a hook, because I'm not making a hotkey or anything, I'm just pressing a button and sending the keystrokes to a window when it's not focused.

Whenever I enter text, even a single character, into a textbox in any Form in my application it causes the form and its parent to close. I've checked for the following so far:
Errant/mis-assigned event handlers that may be interpreting a keystroke as a Form cancel I am using keypreview in several windows but debugging shows this to not be a cause Happens in any form of the application Happens even with brand new text boxes dropped on the form Tried removing the WithEvents declaration from text box declarations (VB.NET)

I'm trying to make use of some functionality from an external app in my program.
My problem is this:
My program manages to start the external app correctly and I can even get the WinHandle correctly if I don't use "ProcessWindowStyle.Minimized" when starting the app.
If I start the app minimized, WinHandle = ProcID.MainWindowHandle returns a 0 and as I understand it, it's
because the app is hidden in the system tray.
How can I start the app minimized and then get the window's handle once it has been minimized?
I've tried various functions like FindWindow and BringWindowToTop but none of them seem to work.

I have an issue in a project trying to auto-scroll down a ListView (used as Details with columns) when adding a new ListViewItem when the window is minimized. I guess we have to use TopItem property to set force the listview to scroll down.I get two exceptions when the form is minimized: "Object reference not set to an instance of an object." "Index (zero based) must be greater than or equal to zero and less than the size of the argument list."
I'm just using standard .Net components (Events/Delegate) with standard way to use them.
I made a small test code to isolate the issue:

I have all the handle capturing and gui set up. I'm stumped as to how to perform the actual step.
I have this code:
SendMessage(New IntPtr(CurrentHandle), WHAT,GOES,HERE?)
[URL]
However, none of these are giving much of the "code example" method that I need to learn how to do it. I just need to send key events such as pressing "/" or "w", etc. No, I can't use sendkeys for this.

I have a filter that is used to populate a grid view and the url will conain: /example/grid?value1=1&value2=2
It will then have a link to page 2, which allows them to edit something.I then want them to click a link that will send them back to the gridview under the same parameters of: /example/grid?value1=1&value2=2
Is this possible? How do I hold on and fill in the URL values so it knows how to refill the grid view accordingly?

I don't really use VB.NET much if not at all, but slowly will change from vb6. [Code] That works fine, apart from when the e-mail is being sent a new window opens for less than a second sometimes (new task) which flashes which is quite annoying. Anyone have any ideas to hide that window flash when sending an e-mail?

I am new to VB.net, i did a course in it about 5 years ago, and could do simple programs, but lost most of my knowledge, because i have not used it in such a long time, now i want to do something and cant seem to get it right, i have this game that i a play online, and i have a few accounts for it, so i would like to make a account logger, wher the usernames and passwords will be saved in a text file, and then i just open the vb program, select the username and the vb program will automatically set focus to the game window (which is windowed, not full screen).
Problem is just, the game client has 4 buttons, New Account, Play Game, About and Credits, i want to get a way for the VB program to set focus to the program(bring it to front, and then move the mouse to the coordinates of the play game button, goto coordinates of the username text box, click and write the username, same for password and then move to login button coordinates and click logon, wait a sec or two and move to either character 1, 2, 3's login button and click)
