I suggest you read about the flags.
When you use the OFN_*MUSTEXIST flags together with the initial file name, you're bound to get that result.

I'm trying to implement a selection tool which naturally creates a selection RECT but can't get it to work the way it should...someone care to fill in the blanks for me...?
DrawFocusRect uses XOR pen so drawing over the exact location as a previous call would remove it and so on. How then would I use WM_MOUSEMOVE to my advantage...?
Each mouse move it would have to:
1) remove itself
2) Draw itself
However neither of the combinations work in either order, so i'm at a loss as to how this would work. I once managed to get simialr effects using OnMouseDown OnMouseUp, but I need only OnMouseMove()
Any idea's...?

Don't bother drawing it yourself. Make use of the CRectTracker class to do it for you.
Create the object in the OnLButtonDown and Destory it in the OnLButtonUp. Change the values in the OnMouseMove.
The only problems I have had with CRectTracker is that you should use a new/delete on it, as the second time you use the same object you get screen corruption. Also, if your control completely redraws between OnMouseMoves's etc, then you have to re-create the CRectTracker object:

Perhaps I didn't explain myself clearly enough. I wrote that message really early in the morning, so I was tired. 
I don't want to use OnMouseUp and OnMouseDown i'm trying to implement a mouse tracker only when the mouse moves. Button clicking has no purpose with this implementation.
Any ideas...? This is where the problem comes in, I can't figure out when to do what...?
Thanx again!

I had to do this once, and there's probably a better way, but here's how I remember doing it off the top of my head(Pardon my pseudocode):
OnMouseDown-
Get the start CPoint, call it pt1
Set a flag to indicate drawing of the rect
moveto(pt1.x, pt1.y)
OnMouseMove-
Check flag to see if drawing a selection rect.
Get the current CPoint, called pt2
DrawRect(pt1, pt2)
{
lineto(pt2.x, pt1.y)
lineto(pt2.x, pt2.y)
lineto(pt1.x, pt2.y)
lineto(pt1.x, pt1.y)
}
Erase any previous rect with XOR.
This requires having saved the previous position of the mouse.
Redraw the rect once the way you want it to appear.
Save the current point as the previous point to so you can erase the old rect on the next mouse move.
OnMouseUp
Check extents of rect and select anything inside.
Set flag to indicate end of drawing selection rect.

I have a class inherited from CToolBarCtrl.How Can I redraw the gripper.
Because CToolBarCtrl doesn't have the member Function DrawGripper(), I can't get any idea.I wonder if somebody can give any advice.But, if I should rewrite my class ,it will drive me mad .

Hi again, i'm sorry ... i wrote my question very bad.
In fact Arabic countries like Saudia Arabic and ... have difference date with Persian countries like Iran. ok ?
But microsoft designed the Hijri date for both of those.
That is more better for Saudi Arabic, and in fact it is not for Iran, Hijri Ghamari is for Saudia Arabic and Hijri Shamsi is for Iran ...
I wanna convert Ghamari to Shamsi, ok ?

I think you have to claculate it in your program,windows does not provide it.

i'm thinking of making lots of libraries (for windows, and/or linux) and the problem i keep running into is naming conventions and standards. basically, i'm not sure whether or not to follow naming conventions for every single function and class i write and have perfectly formatted code and such for every library i make. looking at other libraries, they seem to follow various different naming conventions for variables, functions, class names, etc. and use a variety of different libraries like STL and MFC
what im trying to ask is, can anyone fill me in on the basics of standards and naming conventions, which would best satisfy the people who use my libraries?
p.s. i'd also like to know about how to make 1 DLL for the whole library (instead of 4 - debug, release, MT debug, MT release)
thanks

I don't think there is a universal standard for this. I don't really care what conventions you use inside the code. If I were buying it, I would mainly like to see consistency.
If the library is an improvement/replacement for an existing library, make the API as compatible as possible.
I don't think you can build a single .dll. Even if you manually constructed a file with 4 entry points for each function, there would be no way to resolve which entry point to use, since the call gives no indication of the mode it was built in.
P.S. What sort of library are you building? Is it for public consumption or internal use. Will it be fore sale?
Good luck,
Bill

This is probably going to make some of you laugh but here goes 
I have a dialog base MFC app with a list control in report view. How can i copy the data in the list view class to another list view class in a child window? I have the child window pop up mapped to a button event. Would i have to create a loop to copy the data? or is there a faster way. Please help, Thanks!

If you use the item data field of each list control entry, you could quickly copy just the item data instead of all the column text. In general, this is a better design pattern (Model-View) than stuffing text in a list control. In other words, a list control should know how to render itself based on the data model.

Well, I am using the LV_ITEM datatype for the list. So I guess I should make it into a member variable and access it through scoping?? But wouldn't I still have to get the number of items and loop through inserting each one? I'm not quite understanding your suggestion ravi Can you please be a little more specific, like including a declaration example and how I should initialize my child diag class and/or duplicate list view class. Thanks for the replies!!

But this is assuming that he has only one column of data. What if he has 2 or more cols?

Actually, no. The item data is just a pointer to a blob of data that can be rendered in any manner in the list control. For example, the item data could point to a CMumble object that has multiple members, each rendered in a column. This is how Java's Table UI widget works. It's nice and clean because it separates the data model from the rendering.

so how exactly should I declare this item data type?? I looked around MSDN and it seems like my LV_ITEM datatype is not quite the same as what you are talking about ravi. How should I declare that kind of datatype and some example of how to use it would be awesome! Thanks for all the comments!

You can associate application specific data with items in a list control by calling CListCtrl::SetItemData(). Typically, the item data (a DWORD) is a pointer to an object whose information will be rendered by the list control for that row.
Aside:
The object represents the "model" and the list control (whose only job is to render items and be responsive to mouse and keyclicks) represents the "view" and "controller" in the MVC (model-view-controller) design pattern.
Your (owner drawn) list control will display the appropriate information in each column based on the item's data. When you want to copy chunks of one list control to another (or even within the same list control), all you need to do is to update the target list control's item data for the appropriate rows and invalidate the list control (to force a redraw). You don't need to copy the actual column data of the rows being copied.

That's a really cool solution! I seemed to have missed that member function looking through MSDN  . That should solve my problem, thanks for everyone's help!
