MDI Child Window Maximising - Getting Large Numbers...

Blade[DMS]10-Jul-02 23:22

10-Jul-02 23:22

Hi I have an MDI application which uses multiple resizable formviews for the child windows.
When one of the child windows is macimised, opening another child window results in an OnSize message with a width and height of 32763.
(This is running on Windows 2000)

Any Ideas why this is happening, and how to prevent it???

Thanks...

I'm stuck with a not-more working MMCCtrl.
All of a sudden, the MMCCtrl (MMCs own control used in TaskPads) stopped to function properly.
Only thing I get is a "Object does not support this method".
Well, "this method" does work, at least on other machines with the same MMC installed, and it did on mine until short time ago.

Seems that IE is just messing it up in the HTML which loads that control.

Any ideas????

Hello,

Have you tried just re-registering the control on your machine?

Later,

How to send message to frame window ?

I wnat to send message to every active windows but I got a problem.
If the window with child frame(like Word, Excel...etc.),
it seems not to get the message which I send.
Maybe it's useful to get every frames' handle and send message to every frame.
Does anyone know how to get every handles of frames ?

1) what message are you sending?
2) how are you currently sending it to all windows?
3) (prolly related to #1) how do you know they are not recieving the message?

All I want is to change the scroll lines number.
I used SystemParameterInfo(SPI_SETWHEELSCROLLLINES,...) to change the scroll lines number but in the frame windows(like Word, Excel..etc), and then I send a WM_SETTINGCHANG message to system-wide windows.
'SendMessage(HWND_BROADCAST, WM_SETTINGCHANG, 0, 0)'
But only in frame windows that this parameter don't work.
What should I do?

First, i'm not certain that Office applications actually use this setting. I seem to remember at least Office '97 being a bit strange about handling the mouse wheel. What version of Office are you testing with?

Second, you should be able to use the SPIF_SENDCHANGE flag when calling SystemParametersInfo() to automatically send WM_SETTINGCHANGE to all windows.

Thanks for your help.
I tested with Offce 'XP in Win98.
It's really a little strange about the mouse wheel.
I set 10 line per rotation but it does not work immediately only in the windows with frame windows(like Word, Excel..). In Explorer or Notepad, it works.
If I close Word and launch agagin, this setting works.

By the way, do you know 'SPI_SETSNAPTODEFBUTTON' parameter within SystemParametersInfo(). It seems not work in Win98.
My code is :
SystemParametersInfo(SPI_SETSNAPTODEFBUTTON, true, NULL, NULL)

Once again, you may wish to try adding the SPIF_SENDCHANGE flag to the last parameter. I've never tried it though, so it could just be a bug in Win98.

Well, i found this rather weird. Could you post the source ? It seems that you´re creating things you´re not destructing. Why are you creating a modal dlg on cancel ? Confirmation request for exiting ?

I have a exe through which I call a function of the dll . I want to debug the dll while i Am passing the parameters to that function throught the exe. I have a code of the dll with me .

Can Anyone suggest A solution for it.

I suppose something gets wrong into the dll... if you have the code of the dll, a clumsy solution would be to integrate the function into your main code, and watch the effect. Or make a separate program where you pass the same parameters as in your program (I still believe in the "Same cause, same effects" Smile | :)

)

I think however there should be a better way to do it ...

Load the DLL and the exe project into the same workspace. Make the DLL the active project, set your breapoints etc. When you run in debug (F5) point to your exe program as the one to run and go from there.

what i do is:
open that file of dll into exe in which u wish to go while debuging
u can do it like this
goto file menu option & select open(not open workspace)
then select the file of dll & say ok
if u set break points in that file & then debug the exe the control will go to ur dll file
u can open more then one dll file in exe & also navigate through them using window menu option

Catch WM_MOVING !!!!!

Hi,

I tried to catch a WM_MOVING message in a DialogBar subclass to make it snap to the borders of the mainframe client area when it is floating.

It doesn't work.

Apparently there is another parentwindow (my guess a MiniFrameWnd) built around it when it gets to be floating.

How can I catch or delegate this message in/to my DialogBar ?

Thx

I used to have a life ... now I have a computer

It is possible you will need to use a custom CDockBar class to accomplish what you are trying to do.

That´s exactly what it is supposed to do, so do not worry Big Grin | :-D

I'd suggest :

m_MyCombo.SelectString(0,"hello spotty");

CAsyncSocket reuse

I have Close()'d my CAsyncSocket, but wish to use the same object to restart communications with another socket. How do I go about opening it again? It returs an error, "Descriptor is a file, not a socket."

Thanks.

Hm, my socket objects are dynamic so I just create a new one on request.
If you want to reuse, how abour Close() and then Create()? Didn't try it, but a quick look into Sockcore.cpp shows no problem.

stupid me. of course I also reuse some objects:

m_ClientSocket.Close();	//create new socket (close any pending old socket before)
if(!m_ClientSocket.Create()) {
    m_ClientSocket.Output("** Unable to connect (network error)");
    return;
} //now connect!
m_ClientSocket.Connect(szAddress, nPort);
