[RESOLVED] How to turn backslash to forward slash in windows environmental variable?

[prako2]

I necessarily need to change backslash to forward slash in windows environmental variable. Do you have any suggestions how can I get %programdata% path with forward slash after systemDrive?

TCHAR path[_MAX_PATH];
    _tcscpy(path, programdata);
    _tcscat(path, _T("\\myfile.txt"));
