When i use the func GetWindowRect(), this only returns the current visible window's rect, but i want to get the all scrolling size in this window.(for example GetWindowRect() Get the rect's size is (400*300), but the actual scrolling size is (400*800)).How can i get this value?

What is a "scroll window"?
You can get info for the range of a scrollbar from the scrollbar itself with GetScrollInfo().
If you mean an MFC CScrollView() I believe you can use CScrollView::GetDeviceScrollSizes().

This is new error for me, and MSDN has been less than helpfull on the matter.
bool D3DSpriteBatch::Add( D3DQuad* pQuad )
{
if ( find( m_liBatchQue.begin(), m_liBatchQue.end(), pQuad ) )
return false;
m_liBatchQue.push_back( pQuad );
return true;
}
where m_liBatchQue is an std::list< D3DQuad* >.
The error is
conditional expression of type 'std::list<_Ty>::_Iterator<_Secure_validation>' is illegal

Is your class a template? Can you show the declaration and definition of "m_liBatchQue"?

No, it's just a plain class.
declared as:
std::list< D3DQuad* > m_liBatchQue;
Just your average run of the mill std::list declared as a class member.
I should also note that D3DQuad is itself a standalone class. Well, it's more of a struct with a few ease of use methods.
class D3DQuad
{
D3DQuad( void );
~D3DQuad( void );
};
I have got around the issue by looping the list myself and comparing each member, but I can't understand why std::find is giving me this error. It's not the first time I have created a list of pointers and I have never had this trouble before.

using VC++ 6.0 sp5, Windows XP pro. SP2
I need to give user the ability to edit column structure in CListCtrl.
Problem: when data exists in rows and the user inserts or deletes columns
The row/column data will get mixed up, data will be placed in wrong column.
Microsoft has published Bugs to this effect but it appears to be for older versions.
Is ClistCtrl not capable of dynamic column structuring ?

This is my first time posting to something like this so bare with me.
I am using Visual Studio 2005 and C# but i can integrate visual C++ code using a dll. I've looked everywhere and I can't seem to find a way to do what I want. The goal is to be able to access a GIF file's color table. I'm trying to reduce the number of colors in that image and the best way to do that I am assuming is by accessing the color table and taking the top X number of colors and applying that to the image. I have the applying part working, but the problem is getting those colors to begin with. Currently I am going through the entire image(which is required for my purposes to be 2400 px by 2400 px) and finding the color of other pixel on every other line. This takes a little time and isn't quite as accurate as I would like.
Thanks!

The easiest way I know of is to use GDI+.
If you load the GIF as a GDI+ Bitmap object then you can use:
1) GetPalette()/SetPalette() to read/write the color table
2) LockBits()/UnlockBits() to access the pixel data to change pixels to index the appropriate
entries in the new color table.
3) Save() to save the new image.
With C# you can use the .NET GDI+ wrapper classes (System.Drawing.Bitmap) I believe.
Then you don't have to use C++.

can i remove the ok,cancel&apply buttons provided by the framework when using property sheets and provide my own buttons.Please anyone help me.

Yes... I believe you can get the buttons using a function like GetDlgItem(...) from the property sheet (which is the parent window of the buttons and the pages), and you can then move them, hide them, resize them, or change their text.
You can create your own buttons on the property sheet as well, but if you only need one or two features, you should be able to just change the text on the existing buttons, and override their functionality.
If you have to create your own controls, you will need to manually add message handlers for their events.
Peace!

i'm writing an app with the XLAutomation class included into it, the app builds fine, but when i run it sometimes it seems i can't access Excel (read/write) and then i get this error message:
From the XLAut.. class: "ReleaseVariant: unknown type" and "ReleaseVariant: Array contains non-variant type"
and when i debug the error further:
"Unhandled exception in "MyApp" (OLEAUT32.DLL): 0xC0000005: Access Violation"
And it wont go away even if i close the app and restart it, seems theres something in the memory.
somebody know what this means? any solutions?
thanks

More information would be helpful. Can you show a call stack when the exception is generated and the source code around the line in that triggered it?

What I want to do.[^]
(Server seems a bit flaky, hit reload if it fails)
From the image, you can see I've already figured out that I want to remove WS_EX_CLIENTEDGE from the frame window. Problem is that I can remove it in PreCreateWindow(), but something still draws it anyway. Been looking around (Google searches) and it seems there is some problem when trying to remove WS_EX_CLIENTEDGE from a CFrameWnd used as a splitter view but no one's bothered to post whatever solution they figured out.
|

Try removing the border flags in a WM_CREATE handler (OnCreate()) for the frame window.
I haven't looked through the source but maybe the splitter sets the style later (seems unlikely
but you never know, well unless you look at the source  ).
Also can you sow your PreCreateWindow code? Are you sure you are removing all the appropriate
styles correctly?

BOOL CTabFrame::PreCreateWindow(CREATESTRUCT& cs)
{
BOOL x;
x = CFrameWnd::PreCreateWindow(cs);
cs.dwExStyle &= ~WS_EX_CLIENTEDGE;
return x;
}
I verified that this removes the style by using Spy++/Winspector. Yet the border still shows up. It seems to draw it regardless of the style setting. Can't try the OnCreate() thing right now. Got to go to a meeting.

Thanks. I use this for all my splitter panes and it's ok. You may use other styles in your frame
windows but in my case there's client windows within all of them so I strip all styles except
the two shown.
BOOL CMySplitterPane::PreCreateWindow(CREATESTRUCT& cs)
{
CFrameWnd::PreCreateWindow(cs);
cs.style = WS_CHILD | WS_VISIBLE;
cs.dwExStyle = 0;
return TRUE;
}
Also, make sure any client windowss of frames have their border styles removed as well

Just tried that. Still doesn't remove it.
Not sure what you are referring to by client windows. I'm not all that familiar with MFC doc/view architecture stuff (I kinda wing it, if you know what I mean).

"Client window" is old-school I guess...I came from Borland's OWL framework originally.
Although, I just checked the MFC docs and they still call them clients 
I'm referring to the child window imbedded in a CFrameWnd window - generally created in a
CFrameWnd::OnCreateClient() override. CFrameWnd contains the "decorations" - toolbar(s), menu,
status bar, etc. - and automagically keeps a "client window" positioned within these
"decorations".
Anyway, the fat ugly border is from the splitter. Not only is the splitter bar drawn but (I
assume) to make the bar blend to the sides, the sides are drawn too. Since the splitter is drawn
"raised" there's no way to get rid of it without drawing your own splitter window.
Here's a screenshot[^] from one of my apps. It's the best I've been able to do with the borders
using tab control and splitter window without drawing anything myself. Anything there defferent
from your results?

Looking at your pic it looks like your second toolbar (the bottom one immediately above the tab control) is acting as a parent window, not a sibling window as it should be. Notice how it's right hand side border extends down to and around the bottom of your view, while on the left hand side there is no border present at all.
Look into that as I am going to assume that is where your problem lies, not in the frame window itself.
You may be right
I may be crazy

What are you talking about? The hierarchy goes:
MainFrame w/ Standard toolbar
|- Vertical splitter
|- Tree view
|- Horizontal splitter
|- CFrameWnd w/ Standard toolbar
|- CTabCtrl wrapped up in a view.
|- CScintillaView
|- IWebBrowser2 view
|- CFrameWnd w/ Standard toolbar
|- CReportCtrl (a CP project)
Using ST_SplitterWnd here on CP for splitters.
There's nothing hokey with the toolbars AFAIK - CFrameWnd is managing the toolbar. And the image is a mockup I put together using Photoshop. However, I know it is possible to remove the style because I removed it with Winspector (but the effect was only temporary - resizing the window/moving the splitter restored it even though the style was still gone).

You're not using the MFC splitters? 
The splitter changes the style of the window back to clientedge? Can you remove that from the
splitter code?
