In OnLButtonDown try to deselect m_Bitmap from MemDC by calling MemDC.SelectObject(pOldBitmap).
Also you could declate MemDC as a class member that way in OnPaint you just have to call Bitblt.

Inside 'OnPaint' try using 'CClientDC' instead of 'CPaintDC'

hi,
i am displaying a rectangular box in the window on OnLButtonDown event
using
CClientDC dc(this);
dc.Rectangle(5,5,100,50);
when i minimizing or maximizing the window the rectangular box would vanished
because of OnPaint event
so i try with CDC class to convert all image window Bitmap and store it in
the memory .on OnPaint event i once again call the CDC to show the window image
using
void CChildView::OnLButtonDown(UINT nFlags,CPoint point)
{
CDC MemDC;
CClientDC dc(this);
MemDC.CreateCompatibleDC(&dc);
CBitmap *pOldBitmap = MemDC.SelectObject(&m_Bitmap);
MemDC.SetBkMode(TRANSPARENT);
dc.SetBkMode(TRANSPARENT);
MemDC.Rectangle(5,5,100,50);
dc.Rectangle(5,5,100,50);
}
void CChildView::OnPaint()
{
CDC MemDC;
CPaintDC PaintDC(this);
MemDC.CreateCompatibleDC(&PaintDC);
MemDC.SelectObject(&m_Bitmap);
PaintDC.BitBlt(PaintDC.m_ps.rcPaint.left,PaintDC.m_ps.rcPaint.top,
PaintDC.m_ps.rcPaint.right - PaintDC.m_ps.rcPaint.left,
PaintDC.m_ps.rcPaint.bottom - PaintDC.m_ps.rcPaint.top,
&MemDC,PaintDC.m_ps.rcPaint.left,PaintDC.m_ps.rcPaint.top,
SRCCOPY);
}
Even after using this code , i didn't get the original rectangular box
when i maximizing the window.

In what conditions tree items can not be edited through clicking the label of that item?
I didn't intercept any mouse click message, and the ctrl also has the TVS_EDITLABELS style, but when I click the item label the break point in OnBeginlabeledit(...) doesn't reached.
|

You can edit the label by clicking the item which is currently in the selected state.
I think OnBeginlabeledit wont be fired when you move the focus to a new item by clicking it. Try clicking it again, i think then it will fire the event.

Exact the scenario which I talk about in the original message

I click the item label several times constantly, OnBeginlabeledit just doesn't get fired

Does your tree control "notifies to parent" ?

The ctrl handle the message on its own.
ON_NOTIFY_REFLECT(TVN_BEGINLABELEDIT, OnBeginlabeledit)
ON_NOTIFY_REFLECT(TVN_ENDLABELEDIT, OnEndlabeledit)

Hello.
From your previous posts about the same problem, it seems as if your project files disappears at night, every now and then.
Why don't you make a backup before you leave work for the day?

Now I started taking backup but I think its too late

Hi,All:
I create a subclassed treectrl which allow user drag and drop
but if the Item is without image (neither normal image nor slected image)
,I can't create the Drag image ,it return NULL always.
<br />
SetCapture();<br />
Select(hSelItem,TVGN_CARET);<br />
m_pDragImageList=CreateDragImage(hSelItem);
it works well while item has image.
Can any one help me to point where I am wrong !
Thanks a lot
Don't look at me in that way!

 This behavior seems OK to me. If your item does not have any image, which one should be taken as dragimage ?

But if you drag a item ,the drag image is consist of the image and of course the text.
SO I don't think that the only item which include image and text can be drag and drop!
And I write some code to createDragimage with item which only has text.
but there's some wrong in my code.
That is,I can't check if there is a image with the item.
for Example:
if I retrieve the imagelist of the treectrl and return NULL.Obviously the item do not has a image.
But if the the treectrl return a valid imagelist but the item DO not have a image with it.I use fcuntion GetItemImage(hItem,iImage,iSelImage) to check if the item has a image.but the function always return TRUE.even the item is only consist of text,the parameter iImage,iSelImage will be 0.SO I can't judge if the item has a image with it.
Can anyone help me for this issue!?
Thank you very much!
Don't look at me in that way!

You have to cheat. Create the tree control without an image list. Before calling CreateDragImage, assign an image list to the CTreeCtrl, After the CreateDragImage function returns, assign a NULL image list to the tree control. For example:
m_tree.SetImageList( &m_imageListTree, TVSIL_NORMAL );
m_pDragImage = m_tree.CreateDragImage(m_hDragTreeNode);
m_tree.SetImageList( NULL, TVSIL_NORMAL );
This assumes that you want a tree control WITHOUT images assigned to each item. If you WANT images in the tree control, just call SetImageList when you create the tree control.
You might think that it is possible to assign an image list to the tree control, but for each item say specify -1 as the image index i.e. no image. The problem with this is that it displays the item as if there was a blank image, which is not the same thing.

I wanted to implement a tree like structure similar to the layers control in Photoshop. I am unable to decide which control should I subclass and use for this purpose. Tree control i dont think will be useful for such a task. How about subclassing a Listbox and drawing all the things on my own. Comments please.

I think the SSTab or Tab Control is like the layer control in the photo shop. Is that you are looking? Or what do you mean by layers control?
Nice talking to you.

I wanted information about the controls inside the tab which displays the layers and thumbnails.

I could give one idea. But any way you are going to implementing that. So do like which you feel happy.
I think tool bar is good for that. In a tool bar if we add some check buttons we can get that environment (I think). But may not exactly like that. Or else if we need same exactly like photo shop Layers control, then I prefer we should prepare one activex control which will have two check button options and which can hold one picture and one lable. and it should have the respective events implimented. those controls need to be added to that tool bar. If you show the tool bar in vertical then the look will be same. Am I correct?
Thanks. Have a nice day. 
Nice talking to you.

If I understood you correctly then this listbox[^] should be useful to you.
At least you could add some additional functionalities that you need to this control by yourself.

Hi,Guys
I want to change my console based program into a SDI program. And I have adready make it can work.
But there is one critcal thing left, I don't know how to output the messages used to be displayed in the console to the SDI view.
Can anyone kindly give me some hint or a sample?
Thanks in advance!

Hello.
I think the simplest way to do it is by creating a dialog based application. (I've done the same thing myself).
For the "console", create a listbox and send the console output to it.
