i tested each os that below code in Win98,Win2000.
but different value this variable "procFunc".
i guess wrong value in Win98.
what is wrong? i just get address BitBlt in gdi32.dll.
how can i get right value. gave me your advise.
///////////////////////////////////////
// code start
HMODULE hMod;
FARPROC procFunc;
// Right get value.
hMod=GetModuleHandle("GDI32.DLL");
//or
hMod=LoadLibrary("GDI32.DLL");
// wrong get value.
procFunc = GetProcAddress(hMod,"BitBlt");
////////////////////////////////////////

Are you getting a value other than NULL?
If so, what makes think it is wrong on win98? There is no one value for this function. Depending on the OS or even the Service Pack, it might be different.

it not value is NULL.
so i find same result in WinME.

As long as the value isn't NULL, you shouldn't care at all what the value is. Expect it to be different on every different computer you run the program on. Your software should never care what the value actually is.

I can't seem to figure out how one layers bitmaps. And, can one layer things that aren't bitmaps, like CStatics? Also, what's the best REDO/UNDO method for a publisher-like program?

Manually, by keeping several bitmaps with transparency keys.

No, they don't have a transparent background, unless you're using W2000 or higher ( maybe )

Read 'Design Patterns' for some good ideas. It's on Addison Wesley ( I forget the authors name ).

So, is there a way to do something like save the visual aspects of a CStatic as a bitmap, and then layer it for display? Or would that cause weird laggy stuff for the user, or other lame problems?

If you're not supporting Windows95 you can use TransparentBlt, otherwise search the Windows Developers Journal article backlog at www.wdj.com, I have an article there that shows you how.

Statics are just text, so store the text, and draw it onto a bitmap and show that. Other controls, you have to worry about them getting click messages and so on as well, you should develop a control to hold other controls, display them and get them their messages properly. Sounds like hell to me.

I am having some problems figuring out how to programmitcally group buttons with a toolbar control.
If you want the following:
+-----------------------------------------------+
| btn1 | btn2 | btn3 | | btn4 | btn5 | | btn6 |
+-----------------------------------------------+
\______ _______/ \___ ____/ \_ _/
\/ \/ \/
group 1 group 2 group 3
How do you indicate which group a button is in?
What breaks the group? The separator (ie using the TBSTYLE_SEP) ?

How can I resize an image to half of its size using CxImage? I am having problem findingt the function.
Elizabeth

Why don't you post to the CxImage forum instead of here?
BTW, the function is Resample().
|
|
|

I do not see CxImage forum in CodeProject. Can you tell me the website?

Hello,
Has anyone tried to create custom scrollbars for the ActiveX WebBrowser control? I've managed to disable the default scrollbars using the IDocHostHandler Interface but I'm having a little trouble drawing on the custom ones.
I've found some articles that describe custom scrollbars in listboxes and other controls, but nothing for ActiveX (IDispatch) controls.
I know that you can change the colors through HTML, but there doesn't appear to be a way to use bitmaps in this fashion.
Any help will be greatly appreciated.
Cheers,
Don

I am writing a plugin for winamp 2.xx.
I want to register some Timer for its window.
But how can prohibit to do not conflict by existing its timer ID?
thanks.

Hi
Search for an old pgm. called Eureka (1998) I think.
It deals with some of these issues.

If you own the window the only timers you can confilct with is your own, I think. A handy trick I use with timers is to use existing IDs for timer IDs, that is I associate the timer ID with wath it is related to.
Example: SetTimer(hWnd, ID_MYCLOCK_CONTROL, NULL);
Note: I have yet to see SetTimer() return any ID other than the one that was passed to it, but may be you sould verify the returned value.

Try passing NULL as ID...

If you are subclassing window that already has some timers set: I doubt there is a way to find out what ID's has been used, except by overloading and processing WM_TIMER messages, but of course it could be too late and not reliable...
Good question to ask MSFT!

I know we can do it in DLL.
I have a Static Lib project that develop some class that
they base are MFC classes. I will use this lib in a win32 application.
Some of this class need some resource for example for property page.
If my main program be MFC Base we can it by MFC extention Dll.

I am not sure but I would think so, since the option of staticaly linking is available. If not, just create a DLL and staticaly link it.

No, you can't. The LINK tool can only cope with a single RES file specified on the command line - it cannot combine RES files.
What I've done in this situation is to #include the .rc file accompanying the static library in the main executable/DLL's resource file. See View > Resource Includes in the VC 6 IDE.

I only need to use a command prompt for my program and want to call a couple of WMI methods.
All the examples I see on the web use MFC and Windows Forms for showing how to use WMI.
A simple example would be to just call
Win32_WindowsProductActivation.SetProductKey( myKey );
and then close the app.
I just need a start on what I need to include and do to setup a simple call without using forms.
I am not that familiar with MFC Forms, only .Net Forms, but I do not want to have to install the .Net framework so I thought i would just write this in C++. Also, do not want to use VB Script.
Well, hopefully this is easy for someone to whip up an example for me.
Much appreciated.
Thanks.
