I have created a docking window. And, in the docking window created a listctrl.
I can add items to the list control from within the Create function in my docking window class. No problems there.
However, when I try to add an item to my list control from a menu command within my MainFrame class it fails in IsWindow(m_hWnd).
How can I get a valid pointer to my list control so that I can add items to it without failing because of an invalid window handle?
Thanks,
Frank

I've set up a bitmapped background for my Win32 (no MFC) dialog based app.
The dialog handles WM_CTLCOLORSTATIC by
- SetBkMode (hdc, TRANSPARENT);
- return GetStockObject (NULL_BRUSH);
This -does- let the background show thru like I want.;)
BUT, when I update the static controls' text,
the old foreground is left and the new foreground text
is stamped on top of it makin a MESS. 
Someone else MUST have run across this, right?
Could ya help me out? Thanks!

Rats. Didn't work after all...
I'm doin this:
::SendMessage (statctl, WM_SETTEXT, (WPARAM) 0, (LPARAM) txt);
::InvalidateRect (statctl, NULL, TRUE);
I would think that SendMessage would already invalidate the
whole control...?
Either the background ain't gettin erased by the dialog's
WM_ERASEBKGND
or the control is getting it's draw messages messed up
or somethin???
One last thing - should I be invalidating the whole dialog when
I need to change the static's text?
Thanks for the help tho!
I could send you my src if that'll help...

Did you try to call UpdateWindow(statctl); after that??
Mh2!

Here’s my scenario: I have an application that can save/load project files. I want to be able to register the icon and file extension (*.kkp) with the system so that you can open them directly from within Explorer, and have my app load, but not try to load the project as a document. Instead, I need to be able to detect the file is a project file and then handle it myself.
I know this is possible – I even managed to do it in a previous app I was working on, but now I can’t remember how to do it. Can anybody help?
Yours,
Peter
P.S. Sorry for posting this again, but it got buried under a whole load of other questions as soon as In asked it!

All Explorer does is run your app with the filename as a command line parameter (or whatever you set in the ...\shell\open\command key). How you handle things once you get the filename is up to you. There's nothing requiring you to handle the file as a document.

I have editBox (read only) with spin.
the variable of the editBox is int in range 10 - 2000
and the range of the spin is same.
and all is right.
But when the user try to up the number in the editBox over 999
he gets a error messageBox: "Please enter an integer."
WHY ?????????????????????????????????????????????????
_____________________________________________________________
I ask you about it already and Michael Dann answer me so:
Uncheck the No Thousands property of the spin control - this prevents the control from adding a thousands separator (period or comma) to the number.
_____________________________________________________________
But I did not understand this answer.
Please HELP

I guess it must be trying to put 1,000. "," is not an integer. What Michael Dunn is suggesting is to uncheck that option.

I have a button on a dialog bar, what needs to be done to activate it so it can be clicked?
This is the first time creating a GUI in C++. I have my dialog bar, and want to be able to create message handlers, and edit text in the text boxes, check items....etc in my controls in the dialog bar. Do I need link my dialog bar to a class who's base class is CDialog and access the controls through there....or how else do I got about it?
I was unable to set/clear check buttons either....

IE 5 already has this built-in. You can save a web page as an .MHT file, which contains everything on the page. If you need to do this programatically, look into the IE automation interface docs, and see if saving to .MHT via automation is supported.

Hi,
I would like to know how can I do for transfert a data from a editbox in a TAB PAGE (CTabCtrl) to a dialogbox.
I make this but nothing:
TabPage1 :
EditBox : CString m_edit1;
DialogBox (where the CTabCtrl is) :
EditBox : CString m_edit2;
Button : "handler" CLICK : UpdateData(TRUE);
I create a member variable for the TABPAGE1 :
CTabPage1 m_TabPage1;
Now I can in the DialogBox receive normaly the data from the m_edit1 with this:
m_edit2 = m_TabPage1.m_edit1;
UpdateData(FALSE);
But nothing.
And I make with the pointer to the Class from TabPage1:
CTabPage1 *m_TabPage1;
for TabPage1
and for the DialogBox :
m_edit2 = m_tabPage1->m_edit1;
UpdateData(FALSE);
But nothing.
Please help me for this.

CYourDialog dlg; //(CYourDialog is the class where the CTabCtrl is)
CEdit* pEditdlg = (CEDit*)dlg.GetDialogItem(IDC_EDIT); //Is the Control Id in the tabcontrol
CString str = _T("");
dlg.GetWindowText(str); //Ready
Cheers!!!

Youssef, I'm sorry, I found an error in my answer.
CYourDialog dlg; //(CYourDialog is the class where the CTabCtrl is)
CEdit* pEditdlg = (CEDit*)dlg.GetDialogItem(IDC_EDIT); //Is the Control Id
in the tabcontrol
CString str = _T("");
pEditdlg->GetWindowText(str); //Ready <= This is the corect.
Cheers!!!

another mistake you have,
GetDlgItem instead of GetDialogItem
|
|
|
|
|
Is, true, I don't have pardon.
That is the problem of write directly into CodeProject.
Hey Chris, You need to put a C++ compiler Here....
Cheers!!!!!

I have just started using exceptions, catching both built in types and defined objects. However, as I see it it would be very rare that I actually have a use for doing this. There is always a way around it, usually just error checking. I recall from using java that there are special types defined such as ArrayOutOfBoundsException which you can catch- these types also have relevant methods inluded for diagnosing and working with the exception. Is there no similar concept apart from std::exception...
Thanks in advance..

There is always a way around it
Not always. If you have a library that uses throw to report errors, your only solution is to use try and catch. And don't forget about operator new - it throws an exception when there's not enough memory to satisfy the request. Visual C++ is not up to standard in this area (yet) and will simply return NULL. Hopefully, they will fix this in VC 7 (any Beta2 user to comment on that?)

hello, i really need urgent help with this problem, i look about everywhere but i just can't seem to find an mfc based texteditor program. The problem is this: i have a textbox and i declare a member variable for it as a CString.
Now i have to write the text from this textbox to a file. just like that. i know this really can't be a problem for you guys so please post a quick response here. i can't use getwindowtext and all that because it works with HWND's and u know the mfc stuff is with CWnd.
Thanks

You have two samples in the MSDN, One is the SUPERPAD, and the other one is MULTIPAD.
If you have not the samples I can send you by e-mail.
