I don't know of any easier way -that only means i don't know about it, not that it does not exist- but you could try hooking into the control that hosts the icons on the desktop (i believe it is some derivate of the common list control) and handle WM_NCCALCSIZE[^] to change the client area of this control. Dunno if this would work or not, never tried it, but it might...
[Edit] Also, look at SystemParametersInfo[^] with SPI_GETWORKAREA and SPI_SETWORKAREA for the uiAction parameter of it, these look promising [/Edit]

Few notes:
- The subject should be written using English language.
- Your code is not properly formatted.
- The code looks managed one, i.e. you have missed the right forum.
- There is no question at all.

Hi, Im having MDI application.
In that all childframe have system menu.When i minimized it minimized to down.When maximized its get maximized to full screen.
But what i want is, if i press maximize the window should maximizd to limited width and height.
How can i do that?
I saw OnGetMinMaxinfo(),but i dont know wat parameter should use only for maximizing to certain height and width.
Pls help me.

I think you forget to check MINMAXINFO parameter of the OnGetMinMaxInfo(),
change the value of lpMMI->ptMaxTrackSize, then you can limit the width and height.

yes, i can set width and height of window.
But i want to set X and Y position of window.
How can i do that?

I'd like to create an application that is capable of hooking all input, ie mouse movement and keystrokes that the system recieves. No, I'm not writing a keylogger. If possible, I'd then like to stop those messages in their tracks, add them to a container, and then resend them later on after a specified time period in order to simulate an input delay.
My concern is with the hooking/blocking messages part. Is it possible to do this globally for the entire system?
|
|
|
|
|
Yes it is. Take a look at the function SetWindowsHookEx especially the values WH_KEYBOARD_LL and WH_MOUSE_LL
for the idHook parameter.
With this hooks you can capture every mouse and key input and you also will be able to stop forwarding these messages to the next "hooking" applications and the focused window.
Edit: Except the keystroke "ctrl-alt-delete". You will be able to capture this keystroke, but you will not be able to stop forwarding this keystroke!

Hi, folks
I am thinking of writing a program which opens two files in one window. and these two files needs to be scrolled simulateneously.
(I have to put the scrollbar here as I have multiple views).
I plan to use such a structure
CMDIChildWnd, which has a scrollbar, and CSplitterWnd, its role is to change answer scroll related message such as OnSize, OnScroll.
CView, handles OnDraw, displays file.
CDocument, which has files info.
(I need to take advantage of OnOpenDocument)
the question is, when I load a file (which is handled by CDocument) either by OnOpenDocument() or some user defined open file function, how could I update CMDIChildWnd?
thanks in advance!

You can call UpdateAllViews with a hind to update a particular view
Please refer for more details

thanks for the reply.
but updateview doesn't solve my problem, as scrollbar doesn't belong to a specific view (it belongs to CMDIChildWnd), and I need to update it too.
any idea?
thanks!

I think you dont need to update the CMDIChildWnd.

it is not, it is a CFrameWnd, container of CDocument and CView.
|
|
|
|
|
I think what you want to achieve is update two scroll views from the document?
i.e on update the two views simultanously?

exactly.
but I don't want to use two scrollbars, is it achievable?
|
|
|
|

I hope you want two Views, both derived from CScrollView? and using a single class.
If so then UpdateAllView is what you need.

i planed to use two views, and attached a scrollbar to CMDIChildWnd (i can't attach scrollbar to CDocument, as it is not a CWnd).
UpdateAllView only affect views, but not their container CMDIChildWnd.
If using scrollviews, I need to synchronize two scrollbars.....

I think you can get 2 CScrollViews and manage who is scrolling (the View is active) when you do the click in one of the scrolls, then from the document you get the new scroll position, give it to the other window using SetScrollPosition with pDoc->ActualPos_2 (assuming you made the click on View1) for the other one and call UpdateAllViews. Or just setting the scroll for both views where you need and call UpdateAllViews when opening a document.
Is that more or less what you wanted?
Regards.

Nelek wrote: Or just setting the scroll for both views where you need
could you give a little bit more info?
are both views scrollviews or there is a scrollbar on top of them?
if both are scrollviews, how can I set scroll for both views? which class should handle scroll message?
thanks!

It would be using GetScrollPosition in the view that is getting scrolled with the OnScroll and sending it to the other view where you use it with SetScrollPosition before updating all views.
Yes, both views should be derived from CScrollView and each one would have its own scrollbar, but you synchronize one when moving the other
Here[^] is spoken about SetScrollPos and Here[^] about ScrollToPosition
If you manage the actual position of each View in the document, for instance m_pScrollPos_1 and m_pSCrollPos_2, you can call them in your OnDraw and move the actual position of the scroll for this view to the saved point. When you click on a scroll bar just save the new position in the document and call pDoc->UpdateAllViews.
It may have a bit delayment between the one and the other whilst synchronising. But it is a possibility
