For setting BG color of the RichEdit, check this[^]
|
|

|

Dear Dreamz,
It's easy to set the BG color of a RichEdit Control. What I want to do is get BG color of a dialog (at run time) and then set it to BG color of RichEdit Control.
|
|
|
|
|
overide OnPaint of dialog
use following code 
CPaintDC dc(this);
COLORREF rf=dc.GetBkColor();
m_rEdCtrl.SetBackgroundColor(FALSE, rf);
|
|
|
|
|
I had tried, but it had not met my requirement. I tried GetSysColor and it worked. Thank you prasad_som

you can find here on codeproject
1: Window Capture
2: DDB to DIB
3: SaveDibToFile()
4: Create a printerDC
5: Bitblt the bitmap on the dc
6: EndDocument() --- print
that are the steps...

Hi,
I use DrawFocusRect to draw the focus rectangle of a owner drawn button. I need to change the color of focus rectangle. How can I do it?
Thanks.

Change the system colors. See ::SetSysColors. The color of the focus rectangle surely is one of the system colors.

Sorry, that is not applicable.
Because I use a owner draw button. I only need to change it only. If I change the system color, it will also affect the buttons that do not have owner draw style (I think so!).
Is there any other methods?

Of course. But ::DrawFocusRect is a Win32 API, and as such it'll use the system colors (I don't bet on it - it might just XOR black with the HDC pixels). So, if it doesn't do what you want, don't use it.

Draw the rectangle yourself, of course.

Thank you.
I tried it. But the built in pen styles do not match focus rect line (dotted line).
And creating a user style pen is a complex one, isn't it?
Can you explain the neccessary steps to create a pen just for drawing dotted lines (for focus rectangle)?

Literate programming:
::CreatePen(PS_DOT, 1, color);

Sorry, the result is not exactly as the DrawFocusRect do.
I did the following...
CPen pen(PS_DOT, 1, RGB(255,128,0));
CPen* pOldPen = dc.SelectObject(&pen);
dc.Rectangle(&rt);
The dots are little longer!!!

hi all
i want to load a bitmap from a dll.
i did these:
0- loadlibrary
1- findresource
2- loadresource
3- lockresource
in the last step i get a LPVOID (according to MSDN it is a pointer to the first bit of the resource. i don know what to do after that and how to display it. . does anyone know how should i get this LPVOID to a CBitmap to view it??
oh, am i doing the right thing to load a resource from a dll??
|

If it's really a bitmap (BMP), then use ::LoadBitmap or ::LoadImage instead. They do all the other stuff plus more internally for you. If it's a raw RGB stream you have as a resource, then plug that void* into ::CreateDIBSection or ::CreateDIBitmap.

I really need some example and guide about how to program a sending data under mewtocol command messasge using TCP/IP. Can someone help me.
|

Does anyone know how to get the private memory usage of my program (e.g. "Private Bytes" in the Performance tool).
Thanks!
|
|
|
|
|
Find your 'process' by name, and then under items to add select the Private Bytes to the graph.
|
|
|
|
|
Sorry, should've been more specific. I want to be able to do that from within my program. I hunted around the various APIs, but I couldn't find anything.

Call CMemChecker.ScanMemory();
Examine CMemChecker.m_BytesPrivate
It will be as close or more accurate than the other tool.
If you want how much is used by the DLL and other executable images, then look at
CMemChecker.m_BytesImage
If you want to know how much 'memory' is being used, then look at
CMemChecker.m_BytesCommit
If you want to know how much of your virtual address space has been consumed, then look at total of CMemChecker.m_BytesCommit + CMemChecker.m_BytesReserved
