Send Mouseclicks / Keystrokes Into Minimized Window?
Mar 3, 2009
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]...

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 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?

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.

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

I am trying to send some keys to a program that I launched, but every time i send the keys focus is not on the program and the keys are sent to the wrong program. Is there a better way to send keys to a program or a way to set focus on a certain program?

I am using visual basic code, specifically the sendkeys.send method, to send keystrokes to a different application, in my case Acrobat Reader. Here is my problem. I am sending instructions and text to define a path to a file I want to open in Acrobat Reader. Every keystroke is being sent and interpreted in Reader correctly except the Colon. This is the line of code I am using:Sendkeys.send("C:")
I have tried every variation of this simple line of code I can think of, but the result is the same. Reader for some reason wants to interpret the Colon as Uppercase Q, so what I get is CQ. This of course totally messes up my path to the file I want to open.Sendkeys. sendwait("C:") Behaves the same
I understand there are timing issus with this method so I have added code to my app.config file suggested in this forum for taking care of the timing issue. I have also inserted delays into the execution of the program steps. Nothing I have done solves this problem.I wonder if anyone else has experienced this or a similar problem and if so what was done to correct it.

hello,
i'm trying to build a application for my buddy who plays online games and has asked for a simple program to click the mouse button within his game that he plays for a certain amount of time with a certain duration between. my questions comes ( and i searched but didnt find much useful information for .net framework anyway) about how to detect a combination of keystrokes to start an action and further more to send a click event to the game that should be main focus. i'd also appreciate any tutorials on sending information to other forms controls etc.
thank you for any help

I wrote program that will send keystrokes to a computer if a button is pressed. The button is wired to a db9 connector and plugged into the pc. The program works, except I can not figure out how to detect if the cable gets unplugged. I am monitoring the CD pin change event to send keystrokes, but if the cable is not plugged in then I need it to send a messagebox.

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.

currently my VB Skills aren't so good so bare with me here. application to be able to send keystrokes to another without having it popup. Like it should remain minimized, it shouldn't interfere with whatever you are doing on your PC while it sends the strokes. I received this request from some one else to do. So basically I just need to get focus to the application while it remains minimized and send keystrokes.

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 eveything pretty set up and working the way I want it to but I would the command window pops up when the command is run. I found some code that was supposed to keep the command window in the background but it doesn't seem to work. [b]Can ayone help me figure how to make the command window run in the background or at least keeping if from popping up?/B]This is the code I found. According to the article I read False should keep the command window minimized. I tried it with true and I also tried it with False and neither worked.
objCmd = objWShell.Exec("ping " & url, 0, False)

Ive looked everywhre for an example they all generally don't work. Im trying to click behind the scenes on "Pandoras Desktop App" Its powered by adobe air (i dont know if that makes much of a difference), i can get the hwnd properly, but after that im lost. ive tried Sendmessaging &H201 but it didnt seem to do anything. Also, for most examples they use notepad with the edit class, how would i get classes on pandoras app? or would i just send the mouseclick directly to the parentHwnd?
