CUI & GUI in C++

int CUI Application

#include <windows.h> #include <stdio.h> DWORD WINAPI mainGUI( LPVOID lp) { HMODULE hInstance= 0; hInstance = GetModuleHandle(NULL); HWND hWnd; MSG msg; hWnd = CreateWindow("EDIT", "This window was created from main() and can get messages from the console below.", WS_OVERLAPPEDWINDOW,CW_USEDEFAULT,CW_USEDEFAULT, CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL,hInstance,NULL); if (!hWnd) return (1); *(HWND*)lp = hWnd; ShowWindow(hWnd, SW_SHOW); UpdateWindow(hWnd); while (GetMessage(&msg, NULL, NULL, NULL)) { TranslateMessage(&msg); DispatchMessage(&msg); } return (msg.wParam); } int main(int argc, char* argv[]) { DWORD ID; HWND hWindow; char szOutput[64]; CreateThread(NULL,0,mainGUI, &hWindow, NULL,&ID); printf("This console created the window above./nType in the message you want to send to the window./n/"quit/" to exit./n/n"); while (true) { scanf("%s", szOutput); if (!strcmp(szOutput, "quit")) break; SendMessage(hWindow,WM_SETTEXT, strlen(szOutput), (LPARAM)szOutput); } return 0; }

 

in GUI. to control the CONSOLE Window
