Converting System::String to char *
The official way to convert a visual c++ System::String to a char * could be found here. Such strings are everywhere in windows forms applications.
A simpler way (for people who are used to using standard c\c++) to do the conversion is as follows:
void string2charPtr(String ^orig, char *&out)
{
int length = orig->Length;
out = new char[length+1];
for(int i=0;i<length;i++)
out[i] = (char) orig[i];
out[length] = '';
}
Please feel free to comment on the function above.
