I'd use a vector, of CWnd objects if they are to be different controls, then you can use dynamic_cast to figure out which is what.
in your header:
vector<CWnd*> m_vec_pWnd;
in your cpp:
CEdit * pEdit = new CEdit(provide default parameters);
m_vec_pWnd.push_back(pEdit);
Now you can iterator through the list and set all text boxes to say "STL rules" by doing this:
vector<CWnd*> it = m_vec_pWnd.begin();
vector<CWnd*> end = m_vec_pWnd.end();
while (it != end)
{
CEdit * pEdit = dynamic_Cast<CEdit*>(*it);
if (pEdit)
pEdit->SetWindowText("STL rules");
++it;
}
You may, however, prefer to put them in a map so you can name them and thus identify them by more than their type...

Christian's way is great if you create the controls dynamically at run time.
If you are familiar with VB control arrays and expect the resource editor to do it for you, then NO it wont.
Another way to create a control array AND use the resource editor is to use a vector or map just like Christian suggests, but instead of base it on CWnd*, base it on HWND and call GetDlgItem(IDC_XXX)->GetSafeHwnd(). Populate the vector/map in the OnInitDialog message handler.

I'm sorry, I don't know VB, so I presumed this was what he wanted.

Yea, I'm not sure that is what we wanted either. Its just that I've seen this question come up quite a few times and most of the time it is a VB type person. I've even considered creating a template class to make this possible in VC++, just to permanently answer this question.

I have a Cstatic control in a dialog that draws something lengthy in response to a ON_WM_CTLCOLOR message. I need a way to interupt the process of drawing to do something else and resume drawing when finish. For example i need to have access to other controls and change various options and then resume drawing. Or basically how to have an accessible "stop" button while the drawing goes on, in order to interupt the drawing.
Is there a way without thread ? or any similar example ?
Thanks

Solution: don't do any lengthy processing when handling messages. Especially messages that will be generated while painting. If you don't follow this rule, your application will quickly become painful to use.
Move whatever lengthy processing you're doing in WM_CTRLCOLOR to somewhere else. Draw onto an off-screen bitmap, save the results of your calculations, whatever. Then just use the cached data during message processing. Once this is done, you'll have enough flexability to move the processing into a separate thread if necessary.

I want to send messages to toolbar button to be clicked automatically. I can do that with normal buttons but how can I do that with toolbar. I can get the handle of window by the same old SPY++ technique.But i cant get the button in toolbar. So how can i send a click message to button of a toolbar if i have handle of toolbar and buttons XY location.
In my dream, I was dorwning my §orrow§
But my §orrow§, they learned to §wim

The buttons on a toolbar are part of the control, not individual controls themselves. So, you must send messages to the toolbar control. There are messages meant to change the state of an individual button if you wish it to look pushed (don't remember off the top of my head, check MSDN), but if you just want to fake the effect of the button getting pressed, you can just send a WM_COMMAND message to the window's owner, including the ID of the specific button.

Thanks. But I dont have the control ID and secondly I am out of process. So I cant send NM_CLICK messages to buttons. Secondly I cant get the ToolBar nID to use with GetDlgItem.
Please Please help.

Ok, no matter what you're trying to do, it'll be easier if you can determine the command ID of the specific button. Since i don't know what you're doing, i can't really suggest anything other than using Spy++ to watch the messages sent when you press the button.
Once you have the command ID, you can activate the function by simply sending the toolbar's owner a WM_COMMAND message.

Well thanks a lot. I really appreciate your help. I think I have solved the problem. Here is the procedure.
I get XY of button when user releases mouse over the button.So I also get the Handle to toolbar.To click on button i need handle of button that i can get through
gChildHwnd=::ChildWindowFromPoint(gHwnd,m_stBull.m_point);
this way I get its handle and then send messages WM_LBUTTONDOWN and WM_LBUTTONUP.This works just fine and clicks on the button.Thanks again for your support.

How do i make a true DOS program that can be run in DOS (not in a dos shell like MS-DOS but when you boot the computer into DOS)?
And can i still use libraries like stdlib and iostream or do i need an entirely different approach? I dont so much need an answer for Visual C++ but more in general...
Thanks

First of all you need a DOS compiler, VC++6 can't create DOS executables. When you have the right compiler, you can use all its features.
|
|
|
|
|
Depends the operating system.....
If you are using Win98 or win95, when you boot in DOS mode, you are using the Kernel, in that mode you can use a console project, but if you are using a operating system like MSDOS, you need a old compiler like Turbo C or the Visual C++ 1.0

I suggest that you get a copy of Turbo C++ for DOS. It's a free download from Borland's site

Hi.
I have release one MFC program at my website. I am prepare a second program. In both cases, users that do not have the correct Visual C++ install with the right version of MFC dll cannot run the programs. I have tried compiling a "shared" and "static library" MFC program properties. Users not not having the correct version of MFC dlls on their system cannot run the programs.
What is the best solution such that any user with or without the required MFC dll can run any MFC programs?
Thanks,
Kuphryn

You're allowed to redistribute the MFC dll. There is, however, no reason why a statically linked program should load the MFC dll - are you *sure* that is the problem ?

Yeah. The program was compiled using the "static library" property for the *release*. The reason I could not get Visual C++ to include the MFC dlls inside the executable was because I have set the static library property for the debugger.
Here is my website with the programs I have been working on. I want to thank everyone for giving me pointers to problems and giving me solutions to more difficult ones.

Just link MFC statically and you'll be fine

Hi folks-
I have a CMDIChildWnd based class that has a lot of controls on it. All these controls are "hand-coded". I create them in response to WM_CREATE, resize them in response to WM_SIZE. I am not using a dialog resource for it. (The controls change at runtime based on the state of the application, therefore I dont want to use the Dialog resource)
One problem is: I have lost the ability to tab/shift-tab between the child controls. I have used the WM_TABSTOP style on all the child controls.
After searching all nite in google,cp,cg,msdn,etc..I cant find a way to do it . Can anyone help me with this ??
Thanks-
Vivek

If you call IsDialogMessage for your window, that function will do the dialog control processing for your window. If the message turns out that it is not related to dialog controls, it will automatically call your WindowProc for you.
You should do this in the message pump, or even in the pretranslate message. The point is, you do not want to dispatch the message if you send it to this function.
Good Luck.
