I have the following code which finds a window by a partial name given..
I've tested it and it doesnt work in Dev c++ but it definitely works in visual studio 2008.. So I decided to make a form with nothing on it and implement this code to see if it will work.. The code is below and below that is my attempt.
#include <Windows.h>
#include <iostream>
#include <string>
#include <vector>
using namespace std;
struct FindWindowData{
FindWindowData(TCHAR const * windowTitle)
: WindowTitle(windowTitle)
, ResultHandle(0)
{}
std::basic_string<TCHAR> WindowTitle;
HWND ResultHandle;
};
BOOL CALLBACK FindWindowImpl(HWND hWnd, LPARAM lParam){
FindWindowData * p = reinterpret_cast<FindWindowData*>(LongToPtr(lParam));
if(!p) {
// Finish enumerating we received an invalid parameter
return FALSE;
}
int length = GetWindowTextLength(hWnd) + 1;
if(length > 0) {
std::vector<TCHAR> buffer(std::size_t( length), 0);
if(GetWindowText(hWnd, &buffer[0], length)) {
// Comparing the string - If you want to add some features you can do it here
if(_strnicmp(&buffer[0], p->WindowTitle.c_str(), min(buffer.size(), p->WindowTitle.size())) == 0){
p->ResultHandle = hWnd;
// Finish enumerating we found what we need
return FALSE;
}
}
}
// Continue enumerating
return TRUE;
}
// Returns the window handle when found if it returns 0 GetLastError() will return more information
HWND FindWindowStart(TCHAR const * windowTitle){
if(!windowTitle){
SetLastError(ERROR_INVALID_PARAMETER);
return 0;
}
FindWindowData data(windowTitle);
if( !EnumWindows(FindWindowImpl, PtrToLong(&data)) && data.ResultHandle != 0){
SetLastError(ERROR_SUCCESS);
return data.ResultHandle;
}
// Return ERROR_FILE_NOT_FOUND in GetLastError
SetLastError(ERROR_FILE_NOT_FOUND);
return 0;
}
int _tmain(int argc, _TCHAR* argv[])
{
std::cout << "HWND: " << FindWindowStart(TEXT("foobar "));
std::cout << "GetLastError() = " << GetLastError() << std::endl;
return 0;

}Can anyone help me?? I've never had to convert before but this time I have no other choice =(
And no I don't want to alloc a console and do this.. I want it to run without a console that why I wanted a form.
