Hello: I want to load several excel files at the same time and use tabcontrol to switch activeworkbook, but the activeworkbook property is readonly... I have tried and found that I can do this with just open the file again (i.e excelapp.workbooks.open(....)) and the workbooks.count wouldn't grow up, but this take too much time because the system seems to read the file again. Please help me how to set the activeworkbook by program ? Environment: D7 texcelapplication property: autoconnect : true autoquit : true connectkind : ckRunningOrNew Any suggestion would be appreciated and thanks a lot in advance.

In excel you select the relevant tab, eg: Sheet1.Select (or whatever you have called the worksheet) Oliver Townshend Back to top Carl Yang Guest Posted: Wed Sep 08, 2004 1:43 am    Post subject: Re: How to set excelapplication.activeworkbook by program ? Quote: In excel you select the relevant tab, eg: Sheet1.Select (or whatever you have called the worksheet) Hello: Thanks for your response. The select works for sheet selection. But I try to select one excel workbook from workbooks collection, and the _workbook type not support select method.. I also find that there is a type TexcelOleobject with select method but I can't find how to convert _workbook to _oleobject or Texceloleobject. Please help me: how to select one workbook from workbooks collection and set it as activeworkbook ? Thank you very much !
