I 'm trying to use the Api WriteFile to add data in a file. These datas are strings.
When I declare this information in the section ".DATA" it's working

mystring BYTE "The value"
pstring PBYTE mystring
invoke WriteFile,hFichier, pstring, SIZEOF string, addr nbrBytes, NULL

But, it is more complicated to use variable strings...

I don't know how to declare and affect a value to a variable mystring2

Help !

Thank you in advance.

Instead of pre-allocating space in your program, you can allocate some memory at run-time and use that to store your string. Iczelion has some tutorials which should answer your question. You can find them by doing a google or on this board itself. You might find tutorial 12 on memory management and file I/O particularly interesting.

You can use the memory copy function in the win32 API (memcpy, iirc) or use a loop to copy static data into a dynamic variable.
