Somethings seem HARD to do, until we know how to do them.

have a GUI which uses some of the Registry access functions. What they do is basically read some contents from the windows registry which will be used in the GUI. The problem i face is that,

But if the USER is logged into machine as restricted USER without ADMIN privilages, then the GUI is not able to read registry contents.

I call
pimg.exe and it open the picture viewer in \\My Documents\\My Pictures.
How could I open picture viewer in other path??

But how can use that...

char *str = new char [10];
strcpy(str,"hello\r\n");
int x = strlen(str);
str[x-2] = '\0';
x = strlen(str);
delete[] str;

It won't work, because i can have up to 3 /r/n in the string.

Also do you know if CFile.write will write the null to the file? I was wondering if it could be the reason why I can't add a null to a string.
