到目前为止,这段代码已经工作了很长时间,
抛出异常:
System.InvalidCastException:无法转换类型的COM对象 'System .__ ComObject'到类类型 'Microsoft.Office.Interop.Excel.WorksheetClass'
Dim ds_allJobs As DataSet = DBHandling.searchJob("", "", "all open jobs")
Dim xlApp = New Microsoft.Office.Interop.Excel.Application
xlApp.Visible = False
xlApp.ScreenUpdating = False
Dim xlWorkbook = xlApp.Workbooks.Add(XlWBATemplate.xlWBATWorksheet)
Dim xlWorksheet = New Microsoft.Office.Interop.Excel.Worksheet
xlWorksheet = xlWorkbook.ActiveSheet 'IT FAILS HERE
xlWorksheet.Name = "Open Jobs"
有什么建议吗?
答案 0 :(得分:0)
最好指定对象类型(例如exWorkbook As Excel.Workbook
)
以下是制作新工作表的方法:
'create a new excel application (window)
Dim exApp As New Excel.Application
'add a workbook to it, and take a look at the first worksheet
Dim exWorkbook As Excel.Workbook = exApp.Application.Workbooks.Add()
'create a new worksheet
Dim exWorksheet As Excel.Worksheet
'add this worksheet to the current applicatoin
exWorksheet = CType(exApp.Worksheets.Add(), Excel.Worksheet)
这是否回答了你的问题?最后一行是将对象转换为类型工作表。
