Can you check the values of "line" and "page" scroll in your control? It seems that it doesn't match, and that the control is not erasing the previous lines. BTW, a bit of your code (creation and/or both click messages) would be helpfull
Regards.

Hello -
Does anyone know how an anti-virus software registers itself with windows (i.e. Windows recognizes valid anti-virus software in Security Center)? Is this done through the system registry, or monitored through reports in API calls? Any information would be helpful.
Thanks!

Hello,
i want to resize a loaded bitmap and i thought about to use
the windows method StretchBlt.
I can create a Bitmap out of a ByteArray and I can stretch it
according to the size of the window where it will be displayed
That's my way how i create a bitmap out of a bytearray.
you can see that i use StretchBlt.
CClientDC dc(pWnd);
CDC cdc;
CBitmap* pBitmap = NULL;
CBitmap* pOldBitmap = NULL;
cdc.CreateCompatibleDC(&dc);
dc.SetStretchBltMode(COLORONCOLOR);
::SetDIBits(NULL,hBitmap,0,dwHeight,pData,&Bitmapinfo,DIB_RGB_COLORS);
pBitmap = CBitmap::FromHandle(m_HBitmap);
pOldBitmap = cdc.SelectObject(pBitmap);
if(bStretchMode)
{
dc.StretchBlt(rect.TopLeft().x,rect.TopLeft().y,rect.Width(),rect.Height(),&cdc,0,0,m_iSrcWidth,m_iSrcHeight,SRCCOPY);
}
else
{
dc.BitBlt(rect.TopLeft().x,rect.TopLeft().y,rect.Width(),rect.Height(),&cdc,0,0,SRCCOPY);
}
cdc.SelectObject(pOldBitmap);
ReleaseDC(&cdc);
cdc.DeleteDC();
Now what I want is to load a bitmap from file, resize it and get a pointer
to the bytes of this resized bitmap. i dont need ti display the loaded
bitmap. the loaded bitmap is a binary bitmap,just black and white.
I load the image with this code
HBITMAP hBmp = (HBITMAP) ::LoadImage(NULL,
filename.GetBuffer(),
IMAGE_BITMAP,
0, 0,
LR_LOADFROMFILE |
LR_CREATEDIBSECTION);
BITMAP BM;
GetObject (hBmp,sizeof (BM),&BM);
CBitmap* pBmp = CBitmap::FromHandle(hBmp);
So, any suggestions ?
greetings,
cmos

Yes.
Maybe
Create a second DIBsection, the size and bit-depth you want
Create a memory DC
Select the DIBSection into the new DC
StretchBlt the source bitmap to the memory DC, just like in your code above

Hi,
I'm looking for a tutorial about Unit testing integrated in Visual studio.
I know that Visual Studio 2008 Team suite has the ability to write unit test(the problem is that
The unit test is written in managed C++ while my code is written in unmanaged c++).
Is there any tutorial?
How about another tools(for unmanaged code)?
With best regards,
Eli

I use
WideCharToMultiByte(CP_ACP,0,pBuf,len,pBuf_MBCS,n,NULL,NULL);
to convert.
\n sometimes is converted to 0D 0A, and sometimes to 0A.
Who knows what's the problem?

How do you know that? What is your input string and what about the output one?

One string is very long, it compose a .txt file, about 50 lines, use \n as line break,
another is much shorter, less than 10 lines, also use \n as line break.
After converting, \n in the long one became \r\n, the other is sitll \n.

You may check, possibly with a hex editor (or the debugger), what are the actual linebreaks (i.e what are the UNICODE characters) of the two different strings.

And you should be ranked in top 10 on the THHB category right?
it seems there was a discussion on THHB on the board, can you link me to that.

Hi all,
How to generate beep sound or audio from a system not having speakers in VC++.Net?
I used Beep(freq,mili_secs) to generate a beep from motherboard.Will it work without sound card installed on system?
And how to know diffrent frequencies?
Regards,

Hi Aniket,
I think you should try using the MessageBeep[^] function.
Best regards,

Yes, provided your system satisfy function requirements [^].

Documentation states that frequency maybe genrated in the "37 through 32,767" Hz range.

I have a problem with MDI forms. An MDI form in my application sets focus to a control on it(also scrolls to its location) when the form is clicked/activated/focused. I'm looking a way to prevent it. This is actually a C# application and I have no C++/WinApi knowledge. I tried Spy++ and checked messages it recieves when the mdi form is activated and when this problem occurs. I saw several messages like WM_FOCUS and such. I checked the message number, e.g 0022, and overriden WndProc function of the mdi form and tried to handle it like "if(m.Msg == 0022 || m.Msg == 22)return" for all of the messages includes word "focus" but this didn't do any good. I don't know what else I can do.
This is actually a .NET question I posted here but I thought maybe someone with C++/WinApi knowledge could help me with this. It's driving me insane and I appreciate any help.
