Have you included the file where CCompressor_Dialog is declared?

i included that file but yet there is error
i use VC++6.
i hear if i use newer version this problem can solve
this means that i can include first class into second
and second class into once without error in compiling
can i upgrade my code into newer version of vc++ without any loose?

Do you want to have access of one dialog at two dialog and vice versa?
|
|
|
|
|
first class want to access to second
and second want to access to first just this is my problem

Sounds like a circular reference problem.

Hello all,
Please tell me is it possible to send the WM_KEYDOWN message to the program without pressing any key in the keyboard. I want to call a method which has been written in the keydown event without pressing any key for the first time only. Please help me.
Many thanks in advance.
|

Yes you can send a WM_KEYDOWN message but it doesn't make a lot of sense. Why don't you instead move that specific code into a separate function that you call from within your key down handler and that you can call directly instead of sending the WM_KEYDOWN message.
|
|
|
|
|
You can use the well named (for a change) SendInput funcion. Or rearrange your question to give an answer of "SendMesssage (WM_KEYDOWN,...".
But as Cedric said, this is a TERRIBLE idea if you have any sort of access to the software involved. Otherwise there are lots of errors for you to make. If you don't send a matching WM_KEYUP for example, there could be all sorts of "fun" !
Iain.

If in a Visual C++ 2008 I have an image which i set up by BITMAPFILEHEADER and BITMAPINFO and BITMAPINFOHEADER, how can I enclose it in a device-context so that graphics functions can draw lines and write text on it, as if it was a screen?
Currently the MSDN Library http://msdn.microsoft.com/en-us/library/default.aspx is 404 or not answering queries, else I would have looked in it. When is there the least load on the MSDN Library?

Look for the Cbitmap and CDC classes, where you can make an output.

To DavidCrow: thanks, but in my case the image that I want to write to is already in memory as BITMAPINFO etc bit patterns (without an HBITMAP hande), and does not need to be read from a file.
|
|
|
|
|
Load it in (or create it) as a DIBsection instead -
then you'll have an HBITMAP to use like David's code shows.

That is, please, I want somehow to set up in RAM memory an image object which I can write text to by TextOut() etc via a Device Context (HDC) and also directly by reading and writing its internal data layout.
|

Unless you render the text pixels yourself directly to the
bitmap bits in memory (or use a library that does it for you),
you're going to need to obtain an HBITMAP for the bitmap.
With GDI, a DIBSection works great, and pretty much matches your
current data perfectly.
With GDI+, which has better text capabilities, a Bitmap object is easy
to create from Windows DIB (bmp) data. GDI+ can do this stuff with only
a few lines of code.

I have a program with a set of C++ functions which I wrote to handle image bitmaps directly.
I have been developing this program since around year 1999, and to develop it for a long time I used a good old faithful Borland 5.1 C++ compiler, until I needed a new computer, which came with Windows Vista, which proved incompatible with many old programs and software, and so I had to change to Visual C++.
There is an old (Borland C++) version of this program, including source text, in http://www.buckrogers.demon.co.uk/software/ppp.zip .
It does not use classes (except some classes that I wrote), but calls the Windows graphics functions directly.
But please now I want to be able to write text to those images. So I need some way to set up an image which all of:-
* Has an HDC device-context handle and so can be written to by TextOut() etc.
* Can be written to or from by BitBlt().
* I can access its component bit patterns directly.
