Question

我正在尝试编写一个Winform应用程序并将Excel作为控件停靠在其中。一切正常，直到我尝试从我的c＃app运行Excel宏（用VBA编写）。当此宏尝试访问ActiveWorkBook时，它就是Nothing。

有趣的是，如果我注释掉“SetParent（xlHwnd，this.Handle）;”，则可以使用ActiveWorkBook。好像Excel应用程序的窗口状态正在影响当前的ActiveWorkbook。

以下是我的代码：

xlApp = newMicrosoft.Office.Interop.Excel.Application();

xlApp.WindowState = XlWindowState.xlMinimized;

xlApp.DisplayFormulaBar = false;

xlApp.ShowWindowsInTaskbar = false; 

xlApp.DisplayAlerts = false;

xlApp.DisplayStatusBar = false;

xlApp.Interactive = true;

xlApp.Visible = true;

xlHwnd = (IntPtr)xlApp.Hwnd;

//Windows API call to change the parent of the target window.

SetParent(xlHwnd, this.Handle);

//Wire up the event to keep the window sized to match the control

SetWindowPos(xlHwnd, 0, this.DisplayRectangle.Left, this.DisplayRectangle.Top, this.DisplayRectangle.Width, this.DisplayRectangle.Height, 0X0040 | 0X4);

this.SizeChanged += newEventHandler(Panel1_Resize);

xlWorkbook = xlApp.Workbooks.Add();            

vardbAddIn = (AddIn)xlApp.AddIns[3];            

if(dbAddIn != null)

{

   WorkbookdbWorkbook = xlApp.Workbooks.Open(dbAddIn.FullName);

   if(dbWorkbook != null)
   {

          dbWorkbook.Application.Run("myMacro1");

   }

}

根据MSDN，您必须在宏中使用ThisWorkbook而不是ActiveWorkbook，因为这是包含宏的那个。

从C＃运行VBA宏时，ActiveWorkbook无效
