CreateProcess() c++ file not found

Question

I\'m trying to use CreateProcess to start a child process, however I keep getting error 2, which, according to the documentation is file not found.

Answer 1

The CreateProcess function is very sensitive when it comes to file names, at least in my opinion. When you specify your exe like that you actually specify it according to the current directory which may not be the same as the directory your main exe is in, which explains the file not found. One way around is to simply get your current exe's directory with GetModulePath stip away the exe name from that and there you have the same directory, or simply use an absolute path.

According to the CreateProcess documentation the first parameter can be NULL :

The lpApplicationName parameter can be NULL. In that case, the module name must be the first white space–delimited token in the lpCommandLine string.

At least for me it seemed that if you just specify the command line only it works far better than with the application name, and also within the application name you can't handle the commandline.
