messagebox用法MessageBox 函数

C#中的MessageBox.show的一个用法

private void Form1_Load(object sender, EventArgs e) { if (MessageBox.Show("是否打开", "", MessageBoxButtons.YesNo, MessageBoxIcon.Information) == DialogResult.OK) { //new 出你要打开的新窗体 }else{ this.close();//或者 application.exit（）; } }

MessageBox的使用（C#）

private void Form1_FormClosing(object sender, FormClosingEventArgs e) { e.Cancel = MessageBox.Show("是否关闭", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Question) == DialogResult.Cancel; }

MessageBox 函数

自己写一个格式化MessageBox嘛： #include #include #include int CDECL MessageBoxPrintf(TCHAR * szCaption, TCHAR * szFormat, ...) { va_list pArgList; va_start(pArgList, szFormat); TCHAR szBuffer[1024]; _vsntprintf_s(szBuffer, sizeof szBuffer / sizeof TCHAR, szFormat, pArgList); va_end(pArgList); return MessageBox(NULL, szBuffer, szCaption, MB_OK); } int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iShowCmd) { int year = 2007; const TCHAR* greeting = "Hello!"; MessageBoxPrintf(TEXT("Message"), TEXT("%s This is year %d"), greeting, year); } 或者使用wsprintf： #include int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow) { TCHAR buffer[1024]; int year = 2007; const TCHAR* month = TEXT("Apr."); int day = 11; wsprintf(buffer, TEXT("Today is: %d %s %d"), day, month, year); MessageBox(NULL, buffer, TEXT("Data Report"), MB_OK | MB_ICONASTERISK); }
