Hi!

I implemented an application (named "WinCEApp") using C++ and Windows CE
SDK, that used "ShellExecuteEx" method (see
http://msdn.microsoft.com/library/de...lExecuteEx.asp)
to launch an other application (named "DotNetCFApp") implemented in C# with
..Net Compact Framework. "ShellExecuteEx" mothod passed to "DotNetCFApp"
application a command line argument.

If "DotNetCFApp" application is closed, in this case, when "WinCEApp"
application calls "ShellExecuteEx" method, "DotNetCFApp" is opened with the
correct command line argument passed through "Main(string[] args)" method.

But if "DotNetCFApp" application is already opened (for eg. in minimize
state), in this case, when WinCEApp" application calls "ShellExecuteEx"
method with a new command line argument, "DotNetCFApp" application is
activated but the new command line argument is not passed. After the last
call of "ShellExecuteEx" method I checked the command line argument of
"DotNetCFApp" using P/Invoke for "GetCommandLine" method (see
http://msdn.microsoft.com/library/de...ommandline.asp)
and it returned the old command line argument passed form the first call of
"ShellExecuteEx, not the new one.

I tried to replace "ShellExecuteEx" method with "CreateProcess" method (see
http://msdn.microsoft.com/library/de...ateprocess.asp)
but the results were the same.

Is there anyone who knows how I can activate and pass the new command line
argument to an application that is already running? You can conssider that
both applications are written with Windows CE SDK because I can handle the
Windows CE SDK APIs in a .Net Compact Framework application, too, using
P/Invoke technique. So, any suggestions are wellcome!

I am using Windows Mobile 5, .Net Compact Framework 1.0, Visual Studio
2005, Windows XP Pro.

Thank you in advance!

crossposting can be hard on frequent responders

Of course not. You don't expect the system to call Main() again on a
running program, right? CreateProcess() won't help with this. It could
never work that way. You could create your own method of communicating with
an already-running program and send it information that would otherwise be
on the command line in that way (a user-defined message sent to the main
window, for example, or a point-to-point message queue to which you send the
new data).
