I'm trying to find out how FuncX communicates with it's caller, because it has a void return type and no parameters

I have a hunch that its client application may allocate a buffer for sending or receiving values from the dll. Is this a valid hunch?

Can you debug it from a C or C++ client, so you can step into the function in (native) disassembly mode?

Stuart Dootson wrote:

Sounds possible - but how does the buffer get into FuncX?

Brady Kelly wrote:

I suspect it's at something like a constant, known offset or address in the calling code, if that's at all possible

I'd have to write that client, after a ten minute C refresher, but it's possible, and I'm not scared.

extern __declspec(dllexport) void FuncX();
#pragma comment(lib, "whatever-the-DLLs-lib-file-is");

int main(int argc, char** argv)
{
   FuncX();
}

#include <Windows.h>

typedef void (*FuncXType)();

int main(int argc, char** argv)
{
   HMODULE myDll = ::LoadLibrary(DLL-name);
   FuncXType pFuncX = (FuncXType)GetProcAddress(myDll, "FuncX");
  pFuncX();
}

CString headline;
...
CString Token;
int     Pos = 0;
while (!(Token = headline.Tokenize(_T(","), Pos)).IsEmpty())
{
  //Do whatever you want with the token...

Why write your own bubble sort when the standard library has a quicksort built in.

...but I don't know how to orgnize the bubble sort algorithm in order to compare strings and swap them.

int nNumbers[] = { 1, 7, 4, 10, 3, 5, 6, 9 };
int nCount = sizeof(nNumbers) / sizeof(nNumbers[0]);
...
BubbleSort(nNumbers, nCount);
