The problem probably lies in how you use indexes. Note that array indexes are zero-based i.e. if you have an array holding 5 elements, the last valid index is 4, not 5. Consider [code] const char *article[ 5 ] = {"the", "a", "one", "some", "any" }; int i; // print …

[QUOTE=Frazinray;624316]Is this simply an installation problem?[/QUOTE] Sounds like one, try adding the Dev C++ .\bin folder into your PATH and see if that makes any difference. Might be that the Dev C++ installer does not comply with Vista leaving some things missing.

You need to add a new .cpp file, e.g. Form1.cpp, in which you implement the Form1 class's constructor. [code] // Form1.cpp #include "StdAfx.h" #include "Center.h" // include center.h to be able to construct a CCenter object #include "Form1.h" namespace RCK { Form1::Form1(void) { InitializeComponent(); CCenter^ Engine = gcnew CCenter(); } …

You might post the Form1.h.

This code is capable of only installing and starting the service, it completely lacks the code implementing the actual service, so the error 1053 (ERROR_SERVICE_REQUEST_TIMEOUT) is expected.

I think you could use the following [code] for (int n=0; n <= 8; n++) { if (n != row && Board [row][column] == Board [n][column]) { return false; } if (n != column && Board [row][column] == Board [row][n]) { return false; } } return true; [/code]

You open the port specifying FILE_FLAG_OVERLAPPED, but the WriteFile() call is missing the required pointer to an OVERLAPPED structure. (87 == ERROR_INVALID_PARAMETER)

Whenever you 'delete' something, that something must have been allocated using the 'operator new', without exceptions. The [icode]delete [] List;[/icode] does the damage which is reported.

If I understood, you need to make your window to appear on top, in that case lookup the SetWindowPos() function.

It is some sort of project configuration mismatch, you could post the complete command line of the compiler. Try looking in Project/Properties/Configuration Properties/C/C++/Command Line.

You simply need to initialize the pointers ... [code=cpp] nodePtr head = 0; nodePtr current = 0; [/code] The extern declarations of the pointers you have there, do not impact the actual variables' values in any way, in case you were expecting that to happen.
