如何用vb在excel 2007 vsto中生成单元格点击事件?

您应该能够通过Workheet.SelectionChange事件捕获它,如下面的代码片段所示。如果您对单个单元格感兴趣,则可能需要确保范围是单个单元格。

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
   var sheet = this.Application.ActiveSheet as Excel.Worksheet;
   sheet.SelectionChange += new Excel.DocEvents_SelectionChangeEventHandler(sheet_SelectionChange);
}

void sheet_SelectionChange(Excel.Range Target)
{
   MessageBox.Show("Changed!");
}
