Re: problem with CAssynckSocket::Read

26-Dec-02 5:48

Sorry I'm not home now. But i call Read in the dialog class(from an CMySocket object) like nError=m_sSocket.Read(...) and at debugtime it shows debug assertion fail (nError doesn't take any error value)

the value returned from the Read function is the ammount of data read it's not really used as an error code.. it could be (SOCKET_ERROR).. but to catch error codes in read you should do a

m_sSocket.Read(..)
int nError = WSAGetLastError();

Hope this helps.. If not when you get home you could post some of the actual code.. maybe we can see what the issue is.

How can i get REAL width of the font ?
I've tried this code but it returns me zero !

LOGFONT logfont;
pFont->GetLogFont(&logfont);

int i = logfont.lfWidth;

// i is always ZERO

What's wrong ?

This means that the default aspect ratio is used, which alas gives you little info. Take a look at GetCharWidth32, it could be what you need.

SkinMagic is a powerful library that changes the visual appearance of windows or dialogs, providing developers with full-featured support for 'application skins', or 'application look and feel'. SkinMagic makes it easy to create programs with visually stunning, fully interactive user interfaces.The interfaces can even be created or edited directly at runtime.

With SkinMagic you could make your program look exactly like it was from another OS, or create your own user WinAmp-like "skinned" interfaces, or just give it a different, distinctive look.

thnx

It seems you don't really understand what a DC is. You can't draw lines in a DC, you can draw lines on a bitmap using a DC.

The DC is (among other things) more of a descriptor and abstraction layer of the target device and area.

If you however are sure no one else is selecting a new bitmap into the DC, you could possibly create two DIB sections, select one into the DC, select the other into a compatible DC, and blit the original bitmap into the second one. When you then want to check if anything has changed you can just memcmp the two memory areas.

It would probably be quite slow (I'd expect something like >5 milliseconds for just 640x480x24, even on a moderately fast machine), but short of alternatives it would at least work (maybe you'll have to use 32-bpp to not be bitten by DWORD-alignment and unspecified values at end of every line).

If you are using Memory Device contexts (where you select your own bitmap into the DC) then you can use this function to find the bounding box to the last changes since you ask for the changes:

::GetBoundsRect

However, if you are trying to detect changes on a window, then you will have to resort to other methods.
