Thanks, but:
- what do you mean by Excell automation and how?
- CSpreadSheet creates an excel file, but i want to create a sheet or a table inside the window of my application, so it is not the solution.

Dont worry about that, sounds like you need a grid, see the post from Max http://www.codeproject.com/script/comments/forums.asp?msg=1691852&forumid=1647#xx1691852xx[^] the grid from Chris M has lots of features and will do just what you need.

This is really starting to bug me.
I have created a VC8 MFC app that I am now trying to get to run on a W2K SP4 machine. This app runs with no problems on my XP SP2 machine that has VS2005 installed on it.
I have turned off all optimizations, added all the debug info, and generated .map and .pdb files for the app.
I use DrWatson (drwtsn32.exe v5.0.2195.6699) to generate a .log and .dmp file on the W2K machine when the crash occurs. I transfered those two files back to my dev machine.
I have narrowed the error down to this:
CMyApp::InitInstance()
{
<snip>
CMainFrame *pMainFrame = new CMainFrame;
if (!pMainFrame)
{
AfxMessageBox(_T("Mainframe c'tor failed"));
return FALSE;
}
if (!pMainFrame->LoadFrame(IDR_MAINFRAME))
{
AfxMessageBox(_T("LoadFrame failed"));
delete pMainFrame;
return FALSE;
}
I have absolutely no idea why the LoadFrame call fails, nor why deleting the pMainFrame pointer causes the app to crash. When I try to open the dump file in VS2005 I get an error "Debugging older format crashdumps is not supported."
Here is part of the DrWatson log file in case anybody sees something I may be missing:

What's the value of IDR_MAINFRAME?
I don't think it's crashing where you think it is.... it doesn't look like delete.

It's calling something out of a table. Loads eax with an address of a function (likely from a vtable) and then calls it. The only thing on the stack is a "1".
Just a guess, but the call to LoadFrame would be my guess.
But I am pretty sure it's not the delete statement.

*----> Stack Back Trace <----*Now I do not know why the addresses are different (off by 0x60 bytes)
Why the instruction just before the push 1 is different - VS debugger has it as jz, DrWatson has it as je
Why the pointers are different? mov ecx,dword ptr [ebp-10h] as opposed to mov ecx,[ebp+0xf0]
Is the copy of DrWatson on the W2K machine all screwed up?
If I look for the instruction addresses reported by DrWatson in VS I can not find them.
I assumed that the app was crashing in delete because it crashed immediately after I got the message box and DrWatson reported the fault to be in the code that matches up (almost) with the code the VS shows for the delete function.
Why would the app run flawlessly on XP but crash so badly on W2K? I think what I really need is some clear instructions on how to setup VS2005 to do remote debugging. Anything I have tried from reading MSDN on the subject has failed with VS giving me cryptic error messages.

JE and JZ are synonymous - both jump if the zero flag is set. cmp eax, 15 checks if eax==15. But what it really does is subtract 15 from eax and set the flags appropriately. Thus if they are equal, the zero-flag will be set.
As for the different pointers - the instructions in question have a sign-extended MOD/RM operand. Dr.Watson is for some reason treating the offset as an unsigned char rather than the signed char it really is.
I still don't know why the load addresses are different. You're not doing anything funky with EXE alignment, are you?
It looks to me like memory corruption. It is failing while trying to load the address of the virtual destructor of the pMainFrame object. Somehow the vtbl pointer has been zeroed out. Are you by any chance doing a memset to clear a bunch of class variables? I've seen that many times.
But as to why this fails on only W2K, I have no idea at the moment. What kind of stuff does the app use? (i.e. any os components that could be different on 2k/xp?)
That doesn't really help much, now, does it But it's about all I can think of now.

BINGO !!!!
I was using the CS_DROPSHADOW style on a floating tool window. Removed that style and everything worked.
Thanks much for the hint. You get my 5 for that

Cool! 
I guess I've been reading Raymond Chen's blog enough that some of his "psychic powers" have rubbed off on me! 
But seriously - glad to be of help. Though I still don't get why that caused the problem we were seeing. But at this point it's probably better not to ask.

This code was called from CMainFrame::OnCreate()
BOOL CToolWnd::Create(CWnd *pParent)
{
return CreateEx(WS_EX_TOOLWINDOW | WS_EX_TOPMOST,
AfxRegisterClass(CS_DROPSHADOW | CS_SAVEBITS,
NULL, NULL, NULL),
...);
}I would have thought that the the create function would simply fail to create a window, not crash the entire app. It certainly would have been easier to debug . I have now added code to check the OS and remove the CS_DROPSHADOW style if running on W2K.
Maybe a guy should not ask why, but I would really like to know if anybody has any idea

Looks like CS_DROPSHADOW, flag isnt defined in W2k, SystemParametersInfo[^]

It's more fun when seemingly simple stuff crashes everything.  Would you have looked at a memory dump other wise?
I of coarse just like you would have expected it to just fail at the undefined feature.

I have a series of pages in a wizard; when I press the "next" button to go to the next page, I can validate the current page values in the OnWizardNext and return -1 to stay on the same page if there are some bad values on the page.
but, when I'm at the last page, there's the "Finish" button, and will generate an OnWizardFinish but if there are invalide values on the last page, there is no way (*) of preventing the wizard to finish ( stay on the current page )
(*) I'm certain that there is a way to do it, that's why I'm asking, I think I could disable the "Finish" button and enable it if all my values are valid.
Thanks.
Max.

What happens if you return FALSE from OnWizardFinish()? The docs say it prevents the property sheet from being destroyed, but is that the same as leaving the page open and usable?

I am using VS.NET 2003. I have placed a DateTimePicker and am using time. When I click on the HH field, I can not click (using mouse)on the SS field. I have to exit the dialog then come back in. I realize I can use the keyboard left and right arrows but can I use the mouse to click on the fields after the first is selection.

Or a slightly more readable way:
CHeaderCtrl* pHeader = m_List.GetHeaderCtrl();
int Count = pHeader->GetItemCount();

The Professional version of VC6 came with an optional package for creating InstallShield installation exe's. It will integrate with the IDE and is fairly simple to use for most applications.
