 Thank you very much, but I have to ask a question about "Create", when the function "wcscpy(pClassName, L"seek")" is excuting, the memeory can not be written, that is to say, I can not change the class name, how to do? Thanks.

I have tested my examples and work wery well.
However, if you read again more carefully my previous posts you'll see that I have made some particular presumptions like
- we have a DIALOGEX resource.
- the dialog has attached a menu with ID in the .rc file (not a name).
- a CLASS statement was inserted in .rc file, that we'll replace with a class name with the same length.
If one of them is not respected, most possible you can have troubles.
There are just particular-case EXAMPLES, intended to show you the IDEA.
If you want to deal with all the cases and write a general function, dig deeper in DLGTEMPLATEEX structure documentation, as I already said and modify the code accordingly.
I can do that for you "solving all your homework", but I have not enough time now. And note that it's not for free, although costs only a dozen of beers...

Thanks a lot, the second presumption is not met, because I do not need a menu, so do you mean I have to attach a menu that I do not need in my .rc file? I am so sorry to disturb you again and again, if you can solve my problem completely, I will pay for your beers.  ;P

Beers first!
Well, no menu, then lesser to skip.
WCHAR* pClassName = ((WCHAR*)lpDialogTemplate
+ sizeof(DLGTEMPLATEEX) / sizeof(WCHAR)
+ sizeof(WORD) / sizeof(WCHAR));
And don't forget to take a look in the .rc file to asure you have something like
IDD_DIALOG1 DIALOGEX DISCARDABLE 0, 0, 186, 95
STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU
CAPTION "Dialog"
CLASS "Mama Leone"
However, this is just a patch. As I already said, sweat a little and write a serious function taking care of every case.

OK, Beers is here. 
I have done many tests, and then I found that "wcscpy(pClassName, L"Lama Leone");" can not excuted once I try to change the class name, the other way round, if I did not try to change the class name, this function can be excuted correctly. I think there may be some properties of the resource need be changed, but I do not know what properties should be changed and how. Thanks.

Hi,
I have a menu on a dialog box. There is an option called Grid, which which can be toggled. I want it to be checked/un-checked.
This is what I have done. It looks right to me. But it is not working.
void COption2::OnChartoptionsGrid()
{
IsGrid = 1- IsGrid;
}
void COption2::OnUpdateChartoptionsGrid(CCmdUI* pCmdUI)
{
pCmdUI->SetCheck(IsGrid);
}
Please help.

if you look at the value of IsGrid when OnUpdateChartoptionsGrid gets called is the value as you expect it to be?

Yes. It come 1.
Even if I do not put
pCmdUI->SetCheck(IsGrid);
instead if I put
pCmdUI->SetCheck(1);
nothing happens

Yes. I used the usual class wizard to call it.

While I agree that your recommendation is a better solution (and more readable), what he has will work for toggling:
isGrid = 0;
isGrid = 1 - isGrid;
isGrid = 1 - isGrid;
isGrid = 1;
isGrid = 1 - isGrid;
isGrid = 1 - isGrid;

Are you sure this function is executed when you start the program, open the dialog and click on menu item?
In order to check it, put a breakpoint in OnUpdateChartoptionsGrid (or MessageBox("The function was called") if you are not familiar with debugging). I suppose the function is never executed, that's why it does not have any effect.

Yes! The function IS executed. I put a message box and checked for both. .Thats the terriple part. I added the code to make the grid appear/disappear. Every thing is working fine. Only the check is not appearing.

but the code you would use to make the grid appear/disappear would be in
void COption2::OnChartoptionsGrid()
setting the check mark is supposed to be happening in
void COption2::OnUpdateChartoptionsGrid(CCmdUI* pCmdUI)
There is no default support for calling OnUpdate routines in dialog boxes, there are articles etc... on how to do it.
If you set a breakpoint on the line
pCmdUI->SetCheck(IsGrid);
do you break in to the debugger when your dialog loads?

then I guess that my only other suggestion would be to get a pointer to the CMenu object and call CheckMenuItem directly instead of going through the OnUpdate mechanism. Something is certainly strange here - my code uses pCmdUI->SetCheck without a problem. sorry I can't be more help

I just got an email requesting me to write code for you to help troubleshoot this (I do not see the item yet on the message board). I think the request is a little over the top and my answer is no, I will not write a dialog box based application with a menu showing a working version of SetCheck.
I did, however do a quick google search for "CDialog CMenu" and in less than 5 minutes found others with the same problem that have been helped and a link to a microsoft article explaining a possible solution
http://support.microsoft.com/default.aspx?scid=kb;en-us;242577[^]
did you do any research on this or are you just wanting other people to do your work?

You did not see it on the message board because I did email my request to you.

Oh no. Please dont mistake me. I have struggled with this since two days and only then did I come to codeproject. Because I was'nt getting any errors and debuging showed that the everything is fine I did not know what to do.
My VS does behave unusually sometimes. I have to repetedly delete the debug files and the .ncb files to make things work. I had tried all that but in vain.
Anyway, NOW I know. Thanks a billion for the help. Next time, I shall google first!

Hai
Is there any way in vc++ to round a double value to two(for example) decimal places without using any string function i.e I need the rounded value as a double value but not as a string.
Thanks in advance.
