Could you please elaborate? What kind of code you have and why do you want to call WinMain in your code?

The arguments for main are defined by standards:

int main(int argc, char* argv[])

argc is the size of the argv array, which contains a set of C strings (null terminated). The first string will be the path to the directory out of which the program was launched, ending with the name of the .exe file itself.

An implementation that allows you to invoke main or pass it different arguments would not be compliant with standards. I haven't used WinMain, but my guess is that your choices are to either use it or regular main.

It would be also useful to know what you're trying to achieve.

Unfortunately, I have no experience with WinMain and the other Windows-specific stuff in your code. And your code is neither formatted nor commented, so I doubt anyone will want to spend much time looking at it. It seems that both are similar, so I suggest that you step through each of them, line by line, with a debugger, to see where they behave differently.

thanks i just read from somewhere on net that for security purpose it won't work if taskscheduler runs it...so only option left is to somehow pass these arguments which are in WinMain from main..but how i can still not think of any way as i don't really know what these parameter are doing

Generally speaking, WinMain is the standard entry point for a windows GUI program and main is the entry point for command-line interface (CLI) program. For a CLI program the only parameter of interest is lpCmdLine which is all of the arguments in one string. Normally the arguments are parsed out into separate strings and passed as an array to the main function along with the number of how many there are with the full path to the executable program in slot zero of the array as Greg mentioned.

The bottom line is you can't just pass the arguments along as you have asked. It will require some work to massage the arguments into a form that main can deal with. Besides that, normally one does not call main. If you think you really need to then you are likely to be operating under one misconception or another and you should reconsider your options.

If you are working with MFC you can still obtain the arguments in the argc,argv format like a CLI uses. If not, I don't think so. Regardless, I think it would be best if you modify your question to ask about what your intentions really are.
