_variant_t, WinXP and Win2K ns5-Aug-02 3:56 ns 5-Aug-02 3:56  I have: _variant_t *tempkeyValue = new _variant_t[60]; that executes fine on WinXP but crashes on Win2K. Any ideas why? And how to get around it? Thanks, ns Re: _variant_t, WinXP and Win2K Tim Smith5-Aug-02 4:10 Tim Smith 5-Aug-02 4:10  Somewhere earlier in your program you have trashed the memory and thus the allocation is failing.

Generally speaking, we have some helper function convering from VARIANT to string. Check DAO sample in MSDN to find the helper function. Please, don't send me your email about your questions directly. Have a nice day!

Do you know the easiest way? rechi get cells pnpfriend5-Aug-02 3:25 pnpfriend 5-Aug-02 3:25  hi all, do you know how to get one cell of Excel file? I need to format exiting excel file such as pagesetup, margins, and set the print area. sometime, the file contains 300 pages but 50 pages are empty. So how can i get rid of those 50 empty pages programmatically? thanks. Re: get cells Tomasz Sowinski5-Aug-02 3:41 Tomasz Sowinski 5-Aug-02 3:41  You'll probably have to use Automation. Check the COMEXCEL sample (comes with VC++). Tomasz Sowinski -- http://www.shooltz.com What is "scratch" and why can everything be made from it? Re: get cells pnpfriend5-Aug-02 4:45 pnpfriend 5-Aug-02 4:45  yes.. i'm using automation.. I got everything i needed except for deleting those empty pages... I don't want to print all the empty pagess while i print the file. Normally (not programmatically) I just have to select the area that i want to be printed, then go to next area which contains information, select it again and right click add to print area.. but how can i do the same action promatically??? Re: get cells Tomasz Sowinski5-Aug-02 4:46 Tomasz Sowinski 5-Aug-02 4:46  Well, try to record the VBA macro which does the thing you want. Conversion to VC should be quite easy - it should give you a good start. Tomasz Sowinski -- http://www.shooltz.com What is "scratch" and why can everything be made from it? Re: get cells pnpfriend5-Aug-02 5:14 pnpfriend 5-Aug-02 5:14  huuu... but there is no way (that i know of) to write the macro that delete or get those empty 50 pages out from the 300 pages. Is it clear to you? I have exiting excel file. I open with excel.application. get its worksheets, then sheets, and then sheet. for every single sheet I format it like its font size, page margins, set landscape, set print quality 300 dpi.. and so on.. then I printpreview, in programmatical way. The problem is when you print preview, you will see page number 34 is empty, 55 is empty, 78 - 90 is emtpy, 276-280 is emtpy. nothing to be printed, it's blank page. How can i get rid off those empty pages???? Please help me. Re: get cells Tomasz Sowinski5-Aug-02 5:21 Tomasz Sowinski 5-Aug-02 5:21  Win wrote: How can i get rid off those empty pages???? By deleting the rows? I can't give you any detailed info - it's been a while (about 3 years) since I've been working with automation. Try to achieve your goal in VBA first. Start macro recording, select and delete row of cells - this should give you a way to remove empty spaces.

I'll try that. I'll tried to get the book and tried it. by the way, How can I get the first cell and the last cell? like first cell will be A1 and last cell will be something. is it in string form or in te number? if it's in number form so how to convert the number to string A1 , A2, C1??? So i can use PageSetup::SetPrintArea("A1:K700);? or get the range of the sheet, sheet::range(COleVariant("A1"),COleVariant("C4")) crash when using exit or system menu x ns5-Aug-02 3:02 ns 5-Aug-02 3:02  My project is crashing when I terminate it. My destructor seems to execute okay in the debugger: ~DbClass() { Close(); if(m_pConn) { m_pConn.Release(); m_pConn = NULL; m_strConnection = _T(""); } ::CoUninitialize(); } What should I be looking at to determine why its crashing? Thanks, ns P.S. this only happens if I dont open the database . If I open it and then terminate, everything is fine. Re: crash when using exit or system menu x pnpfriend5-Aug-02 3:32 pnpfriend 5-Aug-02 3:32  what is your application?? dialog based application?
