Many thanks. I forgot to change the prototype (rookie mistake). DCrawford999

Mabye, formoutput really is not a namespace. I am figuring it may well be. void displaychar(int mychar) //outside the namespace { //showchar(mychar); Form1::showchar(mychar); } OR, You may not be including the header file ".\form1.h" witch should define the namespace formoutput. Use #include ".\form1.h" at the top of the source. Then call it, however i bet you might get the error. c:\Documents and Settings\default user.JOSH\My Documents\Visual Studio Projects\Tmle\mlr.cpp(105): error C2352: 'System::Windows::Forms::Form::showchar' : illegal call of non-static member function or something. If so, it means you must first create the class Form1 or gain a pointer to it when it is created from Application::Run(new Form1());

try: this->ioBox->AppendText() DO NOT USE THE dot operator (.) since you are using a pointer you must use the -> operator.

Name mangling is a technique used by the compiler. Each compiler can have different algorithm for name mangling. I don't think its possible to prevent name mangling. Rahul

I've gotten past this problem. Thanks to all Don

Here is a possible short cut: If the C code is part of the project then you could just changed the extention to cpp. Then you will not need to modify it or the header, unless the C code is doing conversions or something else that the C++ compiler wants you to make sure you know what you are doing. Remember that C++ is a superset of C and therefore your C code can be compiled as C++. If you do not whish to change the file extesion then you will need to use the extern "C" any where there is an external C function declared. For future reference you may want to write your C code and test it then change the extesion to cpp and then recompile in order is see where the code can be improved. Make correction then change the extension back to C and retest. This will help improve your C coding and understanding of the C language. Well, good luck. INTP
