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.
View 7 RepliesHow 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.
View 13 RepliesI 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]...

View 1 RepliesI 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.
View 8 RepliesWhenever 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)
What I am doing is making a key shortcut program where the user can set that if he presses a certain key combination from anywhere on his computer while the program is still running, a defined action or program will execute. I know how to use the keyup or keydown to get the key input when the form is focused but how do you get the key input when the form is not focused or hidden. The form will be minimized to an icon in the system tray. I have not started working on the program yet since the whole purpose of the program is this.

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?

View 9 RepliesI'm trying to send a keystroke to a window (of an external executable) but am having problems.
If I launch the exe with a window I can successfully send it a "q" (in order to make it exit) using the follow:
1) AppActivate and SendKeys
2) SendMessage API using WM_KEYDOWN and WM_KEYUP
3) AppActivate and keybd_event or SetForegroundWindow and keybd_event
However, if I launch it without a window, obviously method 1) does not work as SendKeys only work on applications with visible windows, but I thought that method 2) would work. However, it doesn't. Also, using method 3) with SetForegroundWindow as this seems to only work with visible windows, which is not really a surprise I guess, given the name.
Another method I have tried, which won't work is using the RedirectStandardInput - I have this working correctly, but the application is looking for keyboard events, not writes to its StandardInput stream, so this doesn't have any effect.
Finally, I have tried using SendMessage and FindWindowEx, and TranslateMessage, to find any child windows or controls that should be receiving the messages, rather than the main window. However, no child windows or controls are found, and I wouldn't have thought this would be the solution given that, if the window is present, the main window receives the message as it should.
So, I have confirmed that the messages are going to the correct window, as they arrive as they should when the application is launched with a window, but I cannot get the application to receive the message when it is window-less. The solution doesn't have to involve messages, or even be particularly robust, but this is what I have tried so far (all the obvious stuff!)
I am trying to code a program to send keys to a certain window.
For example, in notepad I want the program to write "test" over and over again, in the notepad window. However, I do not want this window to be an active window. Is it possible to make it send keys through a background method?
Want to send the text from my current vb application to the Active Window and that text should be displayed in the text area of the active window.
View 1 RepliesI need to have a VB form that runs out of focus behind another program. When I press "A" (I'll use "A" and "B" as my example keys), "B" is then sent to the program in focus from the VB form and held until "A" is pressed again.
I've worked out how to get it to repeat a key press hundreds of times but I need it to HOLD the key, rather than to just Press and De-press countless times.Here's the piece of code which repeats the letter "A" 100 times:

View 6 RepliesI'm trying to send a single keystroke to an application that has no window (because I have launched it with StartInfo.CreateNoWindow = True) and therefore I can't use SendKeys. I had a look at SendMessage but this doesn't seem to be quite right as the programme I'm sending it to doesn't process message queues.I would usually use the StartInfo.RedirectStandardInput property and send it via a StreamWriter but this doesn't not work as the application it is being sent to is looking for actual keyboard keystrokes, rather than pulling info from StandardInput (an old C++ programme using getch). Anyone have any ideas how to send a keystoke to an application with no window (FYI I don't need anything back from it, I don't need to wait until it's processed, and I only need to send one letter and no carriage returns or linefeeds, though these wouldn't hurt)
