show modal with cmd

To display a modal with cmd using the C language, you can follow these steps:

  1. Include the necessary header files:
  2. stdio.h for standard input/output operations.

  3. windows.h for the Windows API functions.

  4. Declare the function prototype for the modal dialog box callback function: c BOOL CALLBACK ModalDialogProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam);

  5. Define the modal dialog box callback function: ```c BOOL CALLBACK ModalDialogProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) { // Handle the messages for the modal dialog box switch (message) { // Add case statements for specific messages and handle them accordingly // For example, handle WM_INITDIALOG to perform initialization tasks // and handle WM_COMMAND to process user commands. }

    // Return FALSE if the message was not handled return FALSE; } ```

  6. Define the main function: ```c int main() { // Call the CreateDialog function to create the modal dialog box HWND hwnd = CreateDialog(GetModuleHandle(NULL), MAKEINTRESOURCE(IDD_MODAL_DIALOG), NULL, ModalDialogProc);

    // Show the modal dialog box ShowWindow(hwnd, SW_SHOW);

    // Run the message loop to handle the messages for the modal dialog box MSG msg; while (GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg); DispatchMessage(&msg); }

    // Return 0 to indicate successful termination of the program return 0; } ```

  7. Compile and run the program to display the modal dialog box.

In this code snippet, we first include the necessary header files to use the required functions. Then, we declare the function prototype for the modal dialog box callback function. After that, we define the modal dialog box callback function that handles different messages. Next, we define the main function that creates and shows the modal dialog box using the CreateDialog and ShowWindow functions respectively. Finally, we run the message loop to handle the messages for the modal dialog box, and the program terminates when the user closes the dialog box.
