C# - Sendkeys From WPF Application?
Jun 20, 2011
I have an WPF full screen application and I configured Skype´s "Focus Skype" Hotkey to Ctrl+F6 combination.
How can I send this message to windows (Ctrl+F6)? I tried by sendkeys but is not working, it says that: SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method."
I tried Sendkeys.sendwait method but it minimized my full screen application and I need it remains full screen.

I've been developing applications in VB 6 for many years. For a long while now I've not been developing and I switched over to Windows 7. Now I've been asked to build a trainer so I moved over to VB.net 2010 and I'm struggling to make the transition. Anyhow I'm stuck with this trainer.I've been asked by many players of an online game to create an application that serves as a trainer for leveling up characters. I've been personally approached by some of the guilds also. This is an MMORPG so instead of running around for hours, the trainer simulates the keyboard key 1 being pressed which is the attack button. So the character attacks monsters automatically until you stop the trainer. In this way you can leave the game running in the background and do other work.This small project has got me really excited in working in vb 2010 and to me it's a small kick start. I haven't done anything like this is Vb6, it was more database orientated and educational game software I was developing. So I'm clueless in this area.
It doesn't really work. If I activate the ingame chatbox it returns 1 and 49 respectively into the text area but doesn't activate the "attack" command even if the chatbox is deactivated. I'm guessing it's not sending the keyboard press event but instead sending a string?

So I have a form with a textbox1 thats supposed to enter in a set of keywords and then ebay will give you the"Instant suggestions" in return, but when I have my textbox1.text send the text over to the ebay form, ebay will not return any suggestions, unless I use the sendkeys.send method. Well, I do not like the sendkeys.send method because it's way too buggy &only works under the right conditions.Here's a pic of google instant and ebay does the same thing. So here's what I'm trying to get ebay to do:Here's the code that I have:
Dim theElementCollection As HtmlElementCollection = WebBrowser1.Document.GetElementsByTagName("input")
For Each curElement As HtmlElement In theElementCollection

I cannot find any solutions so far using the MSDN search, so I'll just ask the question here. I am trying to make a "bot" so to speak for a game that I play so that I can automate movements and macros. I've never used Sendkeys method yet until today so I am very unfamiliar except for the articles I have seen on the MSDN.
Basically, the game I play I can manually set macro keys like spacebar to perform task. What I want to do is have my application automate this process on a timed basis. Like, every 2 seconds send the key of spacebar to the other application (MapleStory.exe).

I am using SendKeys.Send("{HOME}") in a MaskedTextBox to bring the cursor to the beginning of the textbox when the text is empty. When I try to close the project the application freezes if it doesn't have focus. How do I put this application in focus before I call SendKeys? [Code]

I am automating 3rd party simulation software. The simulation is contained in a DLL. The DLL is programmed to interface though Excel. (Yes I have tried to use the dll outside of Excel, but other factors don't allow it. I have also asked the author to capture the error and recompile the dll)
VB.NET Application
- Excel.exe
-- Simulation.dll
Sometimes a runtime error occurs in the DLL and a dialgo box is created. "On Resume Next" in excel does not bypass the error, nor can I trap this error in the VB.NET application. Currently, if the simulation does not complete in 5 seconds (the DLL error has been thrown and a dialog box is present), I terminate excel application in the following pseudo code manner:
1) Excel.Quit (quit method of the Excel application object model; does not close excel, no error thrown)
2) FinalReleaseComObject() (for all the object references to Excel, workbooks, ranges, etc) <- a
3) Set all excel references to nothing
4) System.Diagnostics.Process.GetProcessById(MyClass.procID).Kill()
A RaceOnRCWCleanup is detected (An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss.) when releasing the Excel application (the other object references do not cause this warning). Is this caused by Excel still being open? I have tried to "find" the error dialog box and close it with some SendKeys, but the an System.InvalidOperationException is thrown: SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method.
I have tried:
1) MyClass.xla.Dialogs.Application.SendKeys("{ESCAPE}")
2) MyClass.xla.Application.SendKeys("{ESCAPE}")
3) MyClass.xla.SendKeys("{ESCAPE}")
4) System.Windows.Forms.SendKeys.Send("{ESCAPE}")
5) My.Computer.Keyboard.SendKeys("{ESCAPE}", True)
6) sending keystrokes to buffer: [URL]
7) Creating a VBS file to send the escape character (doesn't work becuase of the path lenght)
This is what I know about the dialog box from Spy++:
Caption: run-time error
Class Name: #32770 (Dialog)
This program will be running un-attended so I want all debug errors and messages accounted for in code before this goes into production.

What is the difference between SendKeys.SendWait and SendKeys.Send?Send obviously will just send they key immediately, but does SendWait actually wait for the message to be processed or does it also send it immediately?The function's name itself is just confusing. Which one should I use if I want to send keystrokes to a 3rd party app immediately, or is there no difference? To me, a few milliseconds is a big difference.

I have an issue regarding Sendkeys Class, as i want to use this class in order to send some keystroke to the active application. As a first step i want to test the {Enter} keystroke, so in order to achieve that i made a simple application in vb.net 2010
Public Class Form1
Public Shared data As String
Private Sub SendintText(command As String)
[Code].....
By the way in order to use double quotes in a parameter you need "test"...(i have spent 15 min to find out) so it might be usefull...

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
CheckBox1.Checked = True
While CheckBox1.Checked = True
SendKeys("{END}")
End While
End Sub
That is the code, the error is "SendKeys is a type and cannot be used as an expression."

Function to copy whatever the user has highlighted. I have a console ap with hotkeys to open it. It locks up the computer and I have to use TaskMan to free it up. I know this is a simple piece of code but I must have something wrong with the sendkeys line.

I'm looking for the underlying Win32 API call that the DotNET Framework invokes on a SendKeys.Send or .SendWait call, or a Win32 API Equivalent to SendKeys. I've already experimented with SetKeyboardState which seems like the way to go, except that it does not raise any kind of keyboard event that causes the set keystates to register with an active application or the OS (at least not until another key is pressed; for example I can meddle with the keyboardstate before events process on a natural keystroke, but I can't invoke a keystroke programmatically).

I have a VB.Net 2.0 application, on my form I am using a Component ONE PDF reader control.I am trying to send to this control a F4 keystoke to close the navigation panel when it opens the PDF file. It is not working or not accepting the sendkey.I put focus on the control first. Code below:
Me.PDF1.Focus()
Me.PDF1.Select()
My.Computer.Keyboard.SendKeys("{F4}", True)
I have tried different variations of the Sendkeys with no success.

So I've been doing a lot of reading today and apparently SendKeys isn't very reliable anymore.Does anyone know of another alternative to it for what I need:
The application works by the form being positioned over a open window, notepad, word, excel etc and it then determines what it is over, notepad, word, excel etc and then reads the file, and does some processing using SendKeys at the moment.Though I do believe I could probably change the later at some point. The problem I'm having right now is when I try to send the Alt + Tab to change focus it's working roughly 12% of the time.If you are wondering I ran it 50 times and it worked 6 of those,thus the 12%.I'm thinking that is rather unacceptable.This is what I'm using which should work: SendKeys.SendWait("%{TAB}")

First off, using VB2010. I'm in the process of upgrading some applications from VB6 to 2010 and haveing a great time of it. The current application I'm working on is using Sendkeys of which I have changed over to the WSH.Sendkeys of which is pretty decent. Basically the program is copy and pasting the current open file, reading some data and saving it as a different file type. It also has to change xls files to csv and then saving it to the format as well as a smiliar thing with word. Thus the reason for the copy and paste as it's changing the extension to a dot date (for example, test.830).This is the flow of how it works for a text file (most basic)
1. changes focus to notepad
2. Select all Copy to ClipBoard
3. Open Programmers File Editor and a blank file
4. Paste in text
5. Save as code.date extension to the directory
Excel files obviously have a few extra steps.

I'm trying to send some words to an application I'm running (exe file, no webpage). To do this I run my vb program and minimize it, so that the application I want to send the words to have focus.Now I've tried sendkeys, but it seems sendkeys only sends my first word and does nothing with the other words. The code below is called 4 times by the main form
If i > 3 Then i = 0
i = i + 1
If i = 1 Then verhaal ="some text 1"[code]....
but this throws in a overflowexception was unhandled error at the apiSendMessage(hWnd, WM_SETTEXT, 0, "Hello") line.I've tried several things but I can't figure it out how to send multiple words to the application without problems .

I was looking for something send keystrokes and I found this helpful routine SendKeys that I can use in a VB Script. I wanted to have "Right Control Key + (Scroll Lock & Scroll Lock)" sent to the machine. Essentially, having the Right Control Key pressed, I need Scroll Lock pressed twice. Here is what I tried:
set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.SendKeys"^({SCROLLLOCK}{SCROLLLOCK})"
