Forms.Sendkeys. SendWait don't work in Vista

Hi,

I have a beta Vista system and I'm running a program (created in VB.net)
that sends keystroke to an application using
System.Windows. Forms.SendKeys. SendWait. In Vista it throws an exception -
System.Security .SecurityExcept ion: Hook cannot be created.

Is there a way to workaround this problem? I'm logged-in as the system
administrator.

Thanks,
Glenn

Glenn,

Thanks for your post. Our app relies on SendKeys quite a bit and
generates the same error message. We are sending the keystroke to our
own app.

Looking forward to some info from Microsoft.

I've been using the sendkeys.sendwait method in my application to right to another. This works great on some of the systems we have but we have a couple newer Dell laptops that it seems that the all the keys are sent at one time without waiting. I've used the process.WaitForInputIdle method in conjunction with sendwait and it does the same thing. Example: Dim test As Process = System.Diagnostics.Process.Start("test.exe") 'log in...

I have an application that uses SendKeys.SendWait(...) to send RTF (formatting and all) to a word. I was hoping it would parse the formatting, therefore retaining the original formatting of the RTF but it treats the formatting information as standard text and displays it as normal. How do I tell word that I am sending RTF instead of regular text with SendKeys? Is it even possible to send RTF to word without cutting and pasting? Thanks...

Hi, I am relatively inexperienced with VB.Net, but I am familiar with many concepts from programming; I have some basic level of competence with C/C++ and Perl, but I just started using VB this morning. I am trying to write an .exe file that is essentially a script. It will open an application, send it some commands via the keyboard, then wait for the results and close the application.

....with description: " Hook cannot be created" My little program should open an IE window on a specific site, then write in some parameters (with sendkeys function) to login automatically in the page. On XP and IE6 all worked perfectly, but with XP+IE7, sendkeys do not works anymore (any error given), and with Vista here is the SecurityException

Hello, I am trying to send keys to a window using the method above, though I am encountering timing issues, which msdn warned me of before. The way I tried to fix it is polling if the window I want to send keys to is really the focus via: while (GetForegroundWindow() != theHwndWeWant) Thread.Sleep(0); Thread.Sleep(0); // to give some extra time SendKeys.SendWait("our keys");

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
