You sure you have #include "stdafx.h" as the first line in your cpp file?

Hi,
I read in a book that the CDC* in OnDraw function gets removed automatically.My question is-
First ,Is that true?
Second,so, can I use CDC* in my own functions without worrying to release it?
Thanx.

Salut Danielle
Yes, what happens is that the OnDraw is called from the OnPaint method, like so:
void CView::OnPaint()
{
CPaintDC dc(this);
OnPrepareDC(&dc);
OnDraw(&dc);
}
The creation of the CPaintDC causes GetDC and BeginPaint to be called, and its destruction releases the DC and calls EndPaint for you. So the CDC that is passed to OnDraw is yours to work with without needing to release it.
However, unless you have created the view with a special window class that has the CS_OWNDC style (unlikely) you should not store the CDC* for use outside the context of OnDraw.

Hi all,
I have a ComboBox in my dialog ...
My combobox type is Drop List ...
Now, i wanna set text in the combobox, i don't want to add any item, just i wanna put text in combobox edit control ...

When i changed combobox type to DropDown, then SetWindowText will work ...
But how can i do that in Drop List type !

I'm not sure you can do that. The DropList type only shows what is in the list as it doesn't really have the edit control component that the others have.
What effect are you trying to create? It seems strange to want to display text that can't be selected in an Drop List.

Please try using ModifyStyle/ModifyStyleEx.
I didnt try it out, so I am not sure. But it's worth a try.

Can I recommend that you'd be better off using Chris Maunders grid control off this site ?

Hi Christian,
I read this article, but he didn't show how can i connect FlexGrid to DAO !!!
Can you write source code about it ...
I have a DataGrid or FlexGrid, HOW CAN I CONNECT TO DAO ?!
Do you know other Grid's for connecting DAO ?!

You want the grid to automatically populate from a database record ? I've always done it myself, I dunno if you can get the grid to do it for you.

No, I still recommend that you use Chris's grid, and not the MS DataGrid. I've used MSFlexGrid, and hated it. The concept is pretty simple, you iterate through the database, grab the values, and add them to the grid. I used ADO and Chris's grid, and it worked very nicely.

I can't do much beyond reiterating my previous replies - I dunno of an automatic way, I just retrieve the values and enter them into the grid by hand. As in GetRecord/IterateThroughFields/PassEachFieldValueToAppropriateCell.

Hi Chrisitian,
Thanks you for introducing functions in FlexGrid !
Please, please, please if you found useful examples about connecting to DAO with DataGrid or FlexGrid or new other grid control, please send to hadi_rezaie@noavar.com ...
It is my last request of you !
Thanks again, hadi

I am not sure you can delete "c:\windows\temporary internet files"
It's a special system folder [that stores temp IE files]

I've just installed VC++6 on a new P4 system, and I'm having an isolated obscure problem that I'm trying to prove is a problem with my hardware and not with VC++. I get this problem running win2k, XP, and Me.
The problem is that I get a compiler warning C2124 'divide or mod by zero' on a legit line of code:
int main()
{
double a = 1.0; // ok
double b = 2.0f; // ok
double c = a / b; // ok
double d = 1.0 / b; // ok
double e = 1.0 * 2.0; // ok
double f = 1.0 / 2.0; // Error C2124: divide or mod by zero
return 0;
}
I get the same problem with floats, but not ints.
Has anyone seen anything like this, or know of ways of proving that this is a problem with the CPU or mb?
Any help is greatly appreciated!
thanks,
~mark

Well, it might make you happy to know that I got a divide-overflow error on a P-III-600/128MB
int main()
{
double f = 1.0 / 2.0;
}

Nish,
I just tried the code on my PIII 1.2gig 512mb and it worked fine. What version of the compiler and service pack did you try it on.
