This fails with error code 123 no matter if I pass the process name in the first argument (AppName) or the following one (AppArgs) while in http://stackoverflow.com/questions/4053241/windows-api-createprocess-path-with-space former releases the process was created without problems. Does anyone know what has changed in this release and what I'm doing wrong now? I can provide an excerpt of the used code:Soft Declare Function CreateProcess Lib "kernel32.dll" Alias "CreateProcessA" ( lpApplicationName As CString, lpCommandLine As CString, _ lpProcessAttributes As Ptr, lpThreadAttributes As Ptr, bInheritHandles As http://forum.xojo.com/19555-error-123-in-api-call-createprocessa/0 Boolean, dwCreationFlags As integer, lpEnvironment As Ptr, _ lpCurrentDirectory As CString, lpStartupInfo As Ptr, lpProcessInformation As Ptr) As Booleandim bRes as Boolean Const SW_SHOWNORMAL = 1 Const SW_HIDE = 0 Const SW_MINIMIZE = 6 Const STARTF_USESHOWWINDOW = &h00000001 dim ProcInfo as new MemoryBlock(16) dim StartInfo as new MemoryBlock(64) StartInfo.Int32Value( 0 ) = StartInfo.Size ' cb = length of buffer StartInfo.Int32Value( 44 ) = STARTF_USESHOWWINDOW ' dwFlags StartInfo.Int16Value( 48 ) = SW_SHOWNORMAL ' show window normally bRes = CreateProcess( Nil, "C:\Windows\Notepad.exe", Nil, Nil, False, 0, Nil, Nil, StartInfo, ProcInfo)This line doesn't provide a different result either:bRes = CreateProcess( "C:\Windows\Notepad.exe", "", Nil, Nil, False, 0, Nil, Nil, StartInfo, ProcInfo) The function always returns false and an API call GetLastError retrieves 123.Thanks in advance.GreetzPeter Answered by Peter J See post in context Oh sorry of course I can pass arguments via variables in this case, I looked into the wrong branch of the complete code. All in all this solution works fine, thank you very muc
