hello,
i'd like to have a progress control in each MDI document's frame, which holds a CScrollView. in particular, i'm interested in shortening the horizontal scrollbar in a CScrollView, and placing controls to the left of the scrollbar, something like the output view in MSVC 6, or like excel. i searched the articles for something like this, but couldn't find anything. does anyone have any suggestions regarding how to do this?
a simple (but, in my opinion, ugly) solution is to leave CScrollView alone, add a status bar to my CMDIChildWnd-derived frame class, and place the progress control in the status bar.
thanks,

You'll need to stop using the scrollbar that is part of the MDI Child window and use scrollbar controls instead. If you use MFC splitters in your MDI app then it will use scrollbar controls. You might want to have a look at that.
That said it seems strange to me to have porgress controls on the MDI windows. What is taking so long that you need a scroll bar at all, I have to wonder.

i've developed a user interface to some number-crunching code; the user may want to analyze several documents at once without the GUI freezing, so i converted the analysis code to run in separate worker threads. i wanted to indicate progress for each document separately, rather than in the main frame's status bar, so i thought about having a progress control associated with each document/MDIChildWnd.
thanks for the advice.

Ok that makes sense now. Look at the MFC CSplitterWnd code and how it uses CScrollBar. It might be easier to switch to using CSplitterWnd the you'll get the scrollbar's you need. I don't know what would be involved in reducing there size though.

what about adding a progress control below the view in the MDIChildWnd frame? has that been done?
thanks for your advice; i'll check out CSplitterWnd....

I think it would be quite difficult to do as the View window is closely bound to the MDI window. But with enough time anything is possible.
Just did a quick Google search for "CScrollbar MDI" and found:
http://www.codeproject.com/splitter/ruler.asp[^] which may be of interest.

PS. It might be easier to create a child window that sits in a corner of the mdi window and show the progress ctrl there.

Actualy it is not that simple ... because i'm trying to learn and i don't have "Help" nor "MSDN" nor friends that know Visual C++ ...
My problem is with a Check_box .. i'm used to using Delphi ... in this case i don't have Delphi .. i must use Visual Studio C++ ... So I've banged my head in this small problem ...
I whant something like this ... when I click the Check_Box, a Edit_Box that was disabled, to be enabled ... this is what i've come up with :
<b> <code>int checkState;
CButton* pCheck = (CButton*)GetDlgItem(Check_Eagle);
if (pCheck->GetCheck() == 0) {
pCheck->SetCheck(1);}
else pCheck->SetCheck(0);
</code> </b> 
When i hit a Button i whant to do the check ... if GetCheck = 1 then Edit_Eagle = Enabled ... and to enter a value in the same time ... :->:-> ...
can anyone help ?

Actually you do. Check out http://msdn.microsoft.com[^].
When calling GetCheck() and SetCheck(), use BST_UNCHECKED and BST_CHECKED instead of 0 and 1. It has nothing to do with your problem, but it does make the code more readable.

The value passed to GetDlgItem() should be the ID of the checkbox control. Is that what Check_Eagle is, or is it a (int) variable?

<code>Check_Eagle</code> is the name or ID of the Check_box, yes ...

Specify exactly what you are looking for and someone will point you in the right direction.

How do you do what? You've not specified what the problem is. The code snippet in your original post appears to be syntactically correct. What part of it is in error?

not eror ... just that i don't know how to do that ... i'll tell u again ... i whant to make an Edit_Box "Enabled" after i click the Check_Box and to enter a value also .. in te same time ... my problem is with the changing of the status of the Edit_box because of my click ... understand ? 
nu prea ma fac inteles, dar incerc sa ma exprim !!!

Assuming your dialog class has a CEdit member variable mapped to the edit control, you can use:
m_ebEdit.Enabled(pCheck->GetCheck() == BST_CHECKED);

Actually what David meant was:
m_ebEdit.<code>EnableWindow</code> (pCheck->GetCheck() == BST_CHECKED); /ravi

Hummm, most of MSDN is on line (avialable via www). If you're developing the program using the VC++ IDE, then you should already have access to MSDN; otherwise there would be no help avialable when you hit F1. If you are using MFC (via VC++), then activating the class wizard will give you the option of setting the UI options (via command id) as follows:
void MyView::OnUpdateColortypeFill(CCmdUI* pCmdUI)
{
pCmdUI->SetCheck(m_Grid.GetColorType() == CGetColor::FILL);
}

hello everyone...
i have a small question:
i want to intercept keyboard strokes being sent to applications...for example i want the 'a' button to send a 'b' to applications instead of 'a'...should i use hooks or subclassing...i need to know what are the appropiate APIs that should be used..
note:i want this to be done for all applications ((processes)) not only one...

Hook is better , just try global Keyboard hook.

SetWindowsHookEx(...) ,but for Global hook you have to create a dll.
look for more example here :-

it looks like that using SetWindowsHookEx is only for monitoring not modifying...i actually want to prevent a message from reaching applications or modifying that message before reaching them..not just see what the message is...

Actually after hooking you can use GetWindowLong to to get Window procedure of any window and you can modify the charater from there.
look for that in more Detail in the link given by me in last post

if i'm going to do that,i think i have to get the Window procedure of all windows of all processes...i think that's a very hard work..isn't there an easier way..

This is not a small question!
There are aticles at CP that may give you the information that you seak.
I'll tell you this much, you need to use hooks.

After I read some articles about building MFC Dll in this website,
I tried to export my class as MFC dll. However, I also want my class to
handle messages, such as PostMessage, SetTimer, etc.
I want to ask that how can I use message handling ability in my class which is exported as MFC Dll?
Thanks
