I am trying to launch a webpage when a user hits a special key to end the screen saver. The problem is when I use CreateProcess, ShellExecute, or ShellExecuteEx the newly created ie window opens, then closes because my screen saver exits. It doesn't do this when the saver is run by clicking on it in explorer though, or when debugging. It only closes the newly created process when it is activated by windows as a normal screen saver.
What special thing is windows doing to a .scr file when invoked by the system timeout that its not doing to it when you launch it by clicking on it?
Or is there some way I can defer the opening of the browser to another process, such as the desktop window? So then the system won't close it when my saver exits?
I think it may be because the saver is running under a system context when started via the timeout, but when I click on it directly it is run under my user logon context, so maybe I have to use CreateProcessWithLogonW?
Thanks for any help

Are you 100% sure this is the case? Depending on OS and options it could very well be that IE is still running but on another desktop, namely the secured desktop that the screensaver used.
First I'd suggest you really verify with Task Manager that IE isn't running.
If it is, you must redirect it to the default desktop on the default Windows Station (WinSta0). This is sort-of documented in an MSDN article by Matt Pietrek (when he created the equivalent of RunAs for NT4).
If it isn't running, then something must have "killed" it, and about the only thing I can come to think of to see what's happening is that you create a dummy Windows app that logs just about everything that happens to a file (plain ol' printf debugging ).

Yes I am sure IE is not runnning, when the saver exits, the IE process is spawned and you see it in the task manager for a second, then you see the browser pop up and go to the page, then my saver cleans up and exits, then the system kills the IE process.
Thanks for the tip, but I have already tried using "winsta0\\default" and it didn't do anything.
Here is the code I am using:
PROCESS_INFORMATION ProcessInfo; //This is what we get as an [out] parameter
STARTUPINFO StartupInfo; //This is an [in] parameter
ZeroMemory(&StartupInfo, sizeof(StartupInfo));
StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field
if(CreateProcess(NULL, cmdLine, NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo))
{
CloseHandle(ProcessInfo.hThread);
CloseHandle(ProcessInfo.hProcess);
return true;
}
else
{
MessageBox(NULL, errorString, "Error Opening Web Browser", MB_OK);
return false;
}

I have a program that I have been developing under VC++ 7.0. When I try to run the program on a machine that doesn't have Visual Studio.NET it says that it cannot find mfc70.dll. I have set the active configuration to Release but it still doesn't work. Is this just a bug on the the Beta 2 version or am I just doing something wrong. Any help appreciated.

Change the MFC linking mode to "Use MFC in a static library" (or something like that, can't recall the exact wording).

Do you happen to know where to change the linking mode? I'm new to Visual Studio.NET and cannot find it.

Nevermind I found it. Thanks.

Sorry, never used VS.NET. If it's similar to VS6.0, look around Project->Settings.

Well there is some unexpected thing i have encountered while programming in Visual C++ 6.0 under Windows XP. For example, windows standart looklike Button, is light oval shaped and it really differs from buttons in resource editor in visualc++. Even after compilation, the buttons (generally the controls) look like they are from win9x series of windows. Why? Can somebody help me to solve this as i think stupid problem? Example: Miranda compiled on VisualC++6.0 (XP os) has XP style Controls. Is there some definition or declaration that has to be done?

You need to create a ".manifest" file.

If you don't like this style in XP, stop the Themes service and then everything will look like 9x.

i need to get a value of some environment variable. what API can be used to get the value of environment variable

getenv, but I don't think you can get the processor ID with this method.

Didn't know that env variable existed! I've just tried it and it actually returns some info on the processor.

Do you have sample code to get the processor id (assuming it's enabled)? Code to enable it would also come in handy! Thanks,

const char * processor_identifier=getenv("PROCESSOR_IDENTIFIER");This variable is not available on every Windows OS (it is on my Windows 2000, and it is not on the Win98 system I've got home).
