#include <windows.h>

int main(int argc, char* argv[]) {

    HWND hwnd = GetConsoleWindow();
    //Create a Button
    HWND hwndButton = CreateWindowW(
        L"BUTTON",  // Predefined class; Unicode assumed 
        L"OK",      // Button text 
        WS_TABSTOP | WS_VISIBLE | WS_CHILD | BS_DEFPUSHBUTTON,  // Styles 
        10,         // x position 
        10,         // y position 
        100,        // Button width
        100,        // Button height
        hwnd,     // Parent window
        NULL,       // No menu.
        (HINSTANCE)GetWindowLongPtr(hwnd, GWLP_HINSTANCE),
        NULL);      // Pointer not needed.

    MSG msg;
    while (GetMessage(&msg, NULL, 0, 0)) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    return 0;
};

2在main函数中创建对话框

  • 在项目中添加Dialog资源后编写代码。

1.用DialogBoxW函数创建对话框

#include <windows.h>
#include "Resource.h"

int main(int argc, char* argv[]) 
{
    //Eject a Dialog
    DialogBoxW(NULL, MAKEINTRESOURCEW(IDD_DIALOG1), NULL,NULL);
    return 0;
}

2.用CreateDialogW函数创建对话框

#include <windows.h>
#include "Resource.h"

int main(int argc, char* argv[])
{
    HINSTANCE hInstance = GetModuleHandle(NULL);
    //Eject a Dialog
    HWND hdlg = CreateDialogW(hInstance, MAKEINTRESOURCE(IDD_DIALOG1), NULL, NULL);
    ShowWindow(hdlg, SW_SHOW);
    UpdateWindow(hdlg);
    system("pause");
    return 0;
}

3在winamin函数中创建对话框

1.在windows桌面程序中微软将程序的入口点更改为了WinMain。

  1. 更改入口点函数有两种方式，第一种是通过预处理指令更改。Debug模式下仍然会有控制台显示，Release版本不显示控制台

#include <windows.h>
#include "resource.h"
#pragma comment( linker, "/subsystem:\"windows\" /entry:\"WinMainCRTStartup\"" ) // 设置入口地址

int WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
{
    DialogBoxW(NULL, MAKEINTRESOURCEW(IDD_DIALOG1), NULL, NULL);
    return 0;

}
  1. 第二种是在VistualStudio2022中将项目属性->Links->system->SubSystem更改为windows

{

    DialogBoxW(NULL, MAKEINTRESOURCEW(IDD_DIALOG1), NULL, NULL);
    return 0;

}

{
	HWND hdlg = CreateDialog(hThisApp, MAKEINTRESOURCE(IDD_DIALOG1), GetDesktopWindow(), (DLGPROC)DlgProc);
	if (!hdlg)
	{
		return 0;
	}
	ShowWindow(hdlg, SW_SHOW);
	MSG msg;

	{

		DispatchMessage(&msg);
	}
	return 0;
}

INT_PTR CALLBACK DlgProc(HWND hDlg, UINT msg, WPARAM wParam, LPARAM lParam)
{
	switch (msg)
	{
	case WM_INITDIALOG:
		return 0;
	case WM_SYSCOMMAND:
		if (wParam == SC_CLOSE)
		{
			PostQuitMessage(0);//退出
		}
		return 0;		
	}
	return (INT_PTR)FALSE;
}

3 加载菜单

在项目中添加资源文件里的菜单后编码
