1. Absolutely correct, I posted in a hurry.
2. Then you've not set the image index to be the index of your new image in the image list.

- Thanks, warm-hearted Christian pal! 
- Can you tell me how to set the image index to be the index of my new image in the image list? I find the work is easy to think, but it is hard to implement for a newbie, like me.
- Can you help?
- Regards,
BigMouth

OK - the line:
m_wndToolBar.GetToolBarCtrl().GetImageList()->Add(AfxGetApp()->LoadIcon(IDR_MAINFRAME));
returns the index of the new image, and so that is the index iBitmap needs to be set to when creating the new button. The code I posted previously actually did that, you're saying it's not working ?

- Thanks, Christian!
- The method still has a problem. The newly added toolbar button has no image on it.
- Such are my codes: (OnCreate())
int index = m_wndToolBar.GetToolBarCtrl().GetImageList()->Add(AfxGetApp()->LoadIcon(IDR_MAINFRAME));
TBBUTTON btn;
btn.fsStyle = TBSTYLE_BUTTON;
btn.fsState = TBSTATE_ENABLED;
btn.idCommand = ID_FILE_NEW;
btn.iBitmap = index;
m_wndToolBar.GetToolBarCtrl().AddButtons(index, &btn);
m_wndToolBar.GetToolBarCtrl().GetImageList()->Add(AfxGetApp()->LoadIcon(IDR_MAINFRAME));
- Can you help me out?
- Regards,

I don't understand what the last line is for, why add the icon again ?
I also don't get why you need to do it this way, given that GetImageList returns a pointer, but here is what you need:
CImageList * pList = m_wndToolBar.GetToolBarCtrl().GetImageList();
int index = pList->Add(AfxGetApp()->LoadIcon(IDR_MAINFRAME));
m_wndToolBar.GetToolBarCtrl().SetImageList(pList);
TBBUTTON btn;
btn.fsStyle = TBSTYLE_BUTTON;
btn.fsState = TBSTATE_ENABLED;
btn.idCommand = ID_FILE_NEW;
btn.iBitmap = index;
m_wndToolBar.GetToolBarCtrl().AddButtons(1, &btn);
Note that you pass the number of buttons to add to addbuttons, not the index ( which is not even necessarily the index of the button you're adding ).

- Thanks Christian!
- I tried your codes in the OnCreate function of an MDI app. It does not have the desired effect.
- Such is the effect:
1) It removes the 'help' toolbar button.
2) No new toolbar button appears.
3) All the toolbar button becomes a bit bigger.
- I do not know why? Have you tried your codes?
- Can you help, pal?
- Best regards and Merry Christmas to you,

I tested this code on an app at work, and again now on another app at home. It works fine.
Try it again, and try also to take the time top understand *why* it works. That is the path to not having to ask next time, and also to being able to figure stuff out for yourself.

- Thanks, Christian pal!
- Today, I run the app again. I find everything is Ok. But I never change the code!!! Just like yesterday!!!
- Ok, I am puzzled.

- Christian pal!
- I still have a question. How to do the same task from another class? Like the view class? Can you give me a sample code?
- Can you help me?
- Best regards,

#include "MainFrm.h" at the top of the class, then
CMainFrame * pMain = (CMainFrame*)AfxGetMainWnd();
Then do it all the same, just access m_wndToolbar via pMain-> You may have to make it public, or make the view class a friend of CMainFrame.

- Thanks, Christian pal!
- I do not know why the method sometimes does not run stablly. Sometimes it runs ok, sometimes it does not run ok.
- Can you tell me why it happens? Need I refresh something manually?

You need to run it when CMainFrame has been constructed and not destroyed.
When does it crash ?
You can do this:
CMainframe * pMain = dynamic_cast<cmainframe*>(AfxGetMainWnd());
if (pMain)
{
// use it here
}
This is how C++ does run time type information, and although it should *always* work in this case, it gives us a chance to catch if it doesn't. Whenever you request a pointer you should check it first, even if it's just with ASSERT.

- Thanks, Christian pal!
- I still have a question. I think your codes are added to the function OnCreate, so it is sure that the CMainFrame has been constructed.
- So I think there is no need to test whether the "pMain" is NULL. IMHO
- Can you help?

I have a dialog based application which the user accesses through a password. Now there are 2 categories of users and depending on the login and password the application has to display 2 different user screens.
How do I do this?
Also when I first wrote this application I had just one user in mind so all the code is present in the dialog class CApplicationDlg. Is it possible for me to hide all the controls on this dialog box and create a new user screen on the same dialog box when the 2nd user type logs in?
Thanks
Mike.

Well, I guess the simplest way to get this done, given the original design of your project, is as follows:- Create two sets of controls for each user profile and merge them into the only dialog resource. You'll end up with a mess of overlapping controls, so you might want to do the work separately in auxiliary dialog resources and then copy and paste to the final destination. On the process some controls will be shared (i.e., they exist for both user profiles), keep that in mind and do not duplicate them.
- Have all the controls hidden by default. If you select Test on the Resource menu, the dialog should appear empty.
- Have two static arrays defined for your
CDialog class, each specifying the IDs of the controls that should appear for the corresponding user profile.
- Add a variable to the constructor of your
CDialog class indicating the user profile.
- In
OninitDialog you just have to walk thorugh the appropriate array of control IDs and call GetDlgItem(id)->ShowWindow(SW_SHOW).
Hope this helps.

I figured that out thanks. But the problem now is that I need a menu bar for one user category and no menu for the other user category.
By default the dialog box loads a menu bar, and I want to remove it when the user 2 enters. So I did the following
CMenu* menu = GetSystemMenu(TRUE);
menu->DestroyMenu();
But the program crashes!
What do I do?
Thanks,
Mike

Well, maybe you can do it the other way around: by default have no menu in your dialog, and set it when needed with SetMenu.

Lots of information on the net about how to do it. Check for instance How to Create Non-rectangular Windows on the Xploiter website.

Hi,
this should be quite an easy fix, I just don't know how.
I'm writing an internationalised program that has to store text in a file. I cannot for the life of me get the stl ifstream extractor to compile for UNICODE...
i.e. these do not work
TCHAR t[1024];
stream.getline(t,1024,'\n');
...
TCHAR t[1024];
stream >> t;
...
std::wstring w;
stream >> w;
but if I convert TCHAR to char the damn thing compiles. What am I missing? Surely something in the STL templates allow the reading of a double byte character from the stream.
Any pointers appreciated.
Matthew

Use wifstream, which is the instantiation of basic_ifstream for wchar_t (instead of char). Better yet, define a macro of your own for selecting ifstream/wifstream the way TCHAR does.

wicked, thanks. I never even knew wifstream was there.
I am very pleased indeed.

I work in Windows 9x and Window 2000 environment, and I am developing a Win32/MFC application.
I got a question about the one of the "monitor properies" in Windows.
Remember ? When you are in Windows desktop, right click the mouse, and a pop-up menu shows. The last one is "Properties". And when you choose the "Property", there are 6 tabs. The 4th or 5th tab is "Effect". And, there is an item: "Show window contents while dragging".
Now, if I want to set this property ("Show window contents while dragging") in my win32/MFC application, is there any win32 or MFC API I can use in my program to do this ?
Thanks for your help !

It's just a registry setting, therefore you use the registry API.
