Re: Problem of default accelerator in MDI application

29-Feb-04 20:24

In MDI application, Ctrl+Tab is the default accelerator to switch childframe, and Ctrl+F4 is the default accelerator to close active childframe.
My question is: where can I find the code that MFC implements this function, or how can I change the default behavior?

all you need to do is add a accelerator i.e ctrl tab to new command_id

humm
how exactly do you want to reuse and if you dont mind can you say what exactly is ur problem, may be there could be a better solution than overridding the default implementaion.
I belive if you try to change the functionality of the key combination it will alter the way the windows UI works and probably will fustrate the user.

Toolbars in MDI application

Sorry for my poor English, I can't describe it detailed.
I think I've solve this problem. I remove the WS_OVERLAPPED style of my CMDIChildWnd derived class. It seems I can use other method to switch childframes just as ctrl+tab does.
Thank you for your patience!

Re: C++ Simple Class Window

The framework can load some resources for the childframe automatically, such as menu, icon, accelerator and so on. Is there any mechanism to automatically switch toolbar in the framework? If there's none, how can we implement it?

Hello!

Go ahead and check this website out: http://www.relisoft.com/win32/. It has a tutorial on writing win32 base code in c++ framework. Hope this can at least get you started on your project. Smile | :)

Oh, and about wanting to be able to draw certain shapes look at this website: http://www.gametutorials.com/Tutorials/Win32/Win32_Pg1.htm. Download the example code under "Drawing Shapes Using GDI" on the website. Hope that helps!

Later,
Caleb

hi guys,

is there any tutorials relate to how to pass variables from normal c++ program to inline assemble?
and how to change it from character form or integer form to binary form?

thank u very much in advance! =)

i always get a error message "operand size conflict"..
i really dont know wat's going wrong in here, since it's my first time to use inline assemble

thank u =)

mov al,x

its wrong,

al is 8 bit, int is 16 bit,
you should do
mov ax,x
out dx,al

i got the reason, it's 32 bit platform

29-Feb-04 20:47

en, never mind. Thank U very much for ur help =)
really appriciate ur help Big Grin | :-D

jfk_lili29-Feb-04 21:29

Re: i got the reason, it's 32 bit platform

29-Feb-04 21:29

now i hv found the reason for the error, the machine is 32 bit, so the int is actually 32 bit long, to get 16 bits, we need to declare it as "short int"

thank U Prakash
