Thanks for the reply. I did add the variable as control with the ClassWizzard, as you suggested.
Now, however, when I issue the m_cbo.AddString("Your String") command from anywhere within the program, I get an assertion failure (file afxwin2.inl, line 735). Even if I do this: CComboBox c; c.AddString("dd"); it will bomb. Any idea?

You are adding the string before your combo box window (control) is created.

I am adding it upon construction. But even if I add strings well after construction, the code will bomb. Also, as I mentioned in another message, if I run AddString() on a CListBox object (which has no connection with the dialog), the program will throw an assertion too. Does the Wizard somehow require a special way to initialize CObject derived objects? Thx.

It was created with DoModal(). What puzzles me is that I can't even initiate a CListBox object. If I create a CListBox object from anywhere in the program and run CListBox::AddString(), it'll throw an assertion error. Thx.

Hi,
I have two MFC questions (I've looked around but can't find the answers; hoping you guys can help.)
1) I want to set the focus to a certian CEdit control. I'm sure I need to use m_E.SetFocus(?) but how do I get the handle to the dlg that the control is on?
2) I have a dropdown list box that I don't want to let the user type in. Is there a style that I can choose in the dialog editor? setting the "Disable" style grays it out; thats not what i want.
Thanks

1. assuming your dialog is modeless (otherwise, there's little point in having a way to set anything, cause you can't), you will probably have a pointer to an instance of the dialog somewhere. so, you can do m_dlgPtr->m_E.SetFocus();
2. use a real listbox, not a "drop-list" combo.

So if the dlg is modal (which it is) I can't do it? I'm trying to set the focus of the Edit control in OnInitDialog .
In the main form I have:
int nResponse = dlg.DoModal();
Then in OnInitDialog of dlg I read from the registry and depending on what I find there want to set focus to m_E.
Thanks for your help!

ok. i misunderstood. i thought you were trying to set this from outside the dialog class.
but if you're doing this from the OnInitDialog of the dialog itself, then yeah, just do m_E.SetFocus() (and then return FALSE from OnInitDialog).

Thanks. It was the returning FALSE that did it. Nice catch w/o even look at my code!

Where did it go in VC.NET. Damn, I can't find it.
I would like to catch a home made message, and I used to use PretranslateMessage to do that.

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

Hello again,
Can anybody help me add Rebar to a CDialog. The SDK dlgbars and MSCIE samples, which many people quote on newsgroups as solutions, aren't enough.
The toolbar, which the Rebar is to contain, must inherit from a user-defined class based on CToolBar in order for for UpdateUI handlers to work, as shown in the dlgbars sample. However, when I try to add the new Toolbar to the Rebar, the icons are disabled.
Thanks.

In my app i use the functions ImageList_Create and ImageList_AddIcon which are defined in the commctrl.h header file. When i try to compile the application these error messages appear:
main.obj : error LNK2001: unresolved external symbol __imp__ImageList_ReplaceIcon@12
main.obj : error LNK2001: unresolved external symbol __imp__ImageList_Create@20
The ImageList_Create makes creates the "__imp__ImageList_Create@20" error and the "ImageList_AddIcon" creates the "__imp__ImageList_ReplaceIcon@12" error.
Does anyone know how to resolve this problem?
Thankyou

are you linking to comctl.lib / comctld.lib ?
(you need to)

I have just included the commctrl.h file, how do i choose which file i want to link to?
|
|
|
|

this should actually be happening automatically, if you've #included commctrl.h. but, comctl.lib for release and comctld.lib for debug.
-c
"Should you not have a ramekin of sea salt beside the stove, you don’t deserve oatmeal."

How do i find out what file it's linking?
|
|
|
|
|
When i press ALT+F7 and add the comctl.lib and comctld.lib to the list under the Link tab it says, when i try to compile it, that it can't find the files.
|

Do i need them? I just looked in the commctrl.h header file and found the following block:
#ifndef _WLMDLL
#ifdef _DEBUG
#pragma comment(lib, "comctld.lib")
#else
#pragma comment(lib, "comctl.lib")
#endif
#pragma comment(linker, "/macres:comctl.rsc")
#else
#ifdef _DEBUG
#pragma comment(lib, "msvcctld.lib")
#else
#pragma comment(lib, "msvcctl.lib")
#endif
#endif // _WLMDLL
looks like the files are needed, are they?
