For some reason this doesnt work

invoke CreateProcess,application_path,commandline_buffer,0,0,FALSE,NORMAL_PRIORITY_CLASS,0,0,sinfo,pinfo

Has anyone got any idea why commandline_buffer is not being recieved by application, Im testing by using MessageBox to show the command line paramters , they show ok when I drag and drop a file onto the application, but come up blank when I use the createprocess as above

app shows a commandline string when I drag and drop a file onto it, but when I use createprocess the "commandline_buffer" doesnt show in the messagebox, ie blank !!!! ???

got me stumped, thanks in advance for any help !

I did try for an hour to fix it before asking ....

With just that single line you posted we can't tell you what you are doing or what the contents of the various parameters are that you are passing. Perhaps you can post some simplified example code that we can compile and test.

I solved it after many frustrating attempts...

invoke CreateProcess,0,apppath_and_commandline_buffer,0,0,FALSE,NORMAL_PRIORITY_CLASS,0,0,sinfo,pinfo

we need a dislike button.
