Error that I get:

Code:

113 C:\Programs\Dev-Cpp\Templates\solaris3.cpp invalid conversion from `TCHAR' to `const char*'

Try changing

Code:

strcat(mamu,(TCHAR)wParam);

to

Code:

strcat(mamu,(TCHAR*)wParam);

If I use TCHAR* or char* or const char* I always get illegal operation message.

Try using the conversion function A2T() instead of just trying to force a TCHAR

thanks for the clarification. been trying to teach myself windows programming..still have a long ways to go.
