What do you mean by "in the caption"
Would

GetDlgItem(ID_CLOSE)->EnableWindow(FALSE);

do?

A vast majority of our imports comes from outside the country.

The heading is such bar, at the top of dialog in which the heading of dialog is written and on the right there is a button to close as [x]

What's the ID_CLOSE

I don't think it's possible unless you draw the caption and its buttons yourself in WM_NCPAINT.

Why do you need this functionality?

In some cases it is necessary for me to forbid for the user to make a cancellation, and button Close is equivalent to a cancellation!

Disabling the menu items in system menu disables the buttons on the Caption Bar.

The following code should do:

CMenu *pMenu= GetSystemMenu(FALSE);
pMenu->EnableMenuItem(SC_CLOSE,MF_BYCOMMAND|MF_DISABLED);
pMenu->RemoveMenu(SC_CLOSE,MF_BYCOMMAND);

Nice trick! Big Grin | :-D

I've checked this on W2K - it's enough to call EnableMenuItem. Also, if for some reason it's OK to leave disabled item in the system menu, then MF_GRAYED instead of MF_DISABLED will be better - the menu item will actually look disabled.

I'm glad you got it working, but you may consider that instead of disabling the Close button, you let the user press it but then show him a message box explaining why it's wrong to do so. Sometimes this is a more user-friendly way to go, since it doesn't leave the user wondering why he can't do something he's normally allowed to do (like closing windows), and then perhaps picking up the phone to ask Tech Support. If you tell him with a message box, he'll know right away.

Alvaro

Very good remark, but I do not know as it is possible to handle the message from the button taking place outside of client parts of dialog!
Therefore I while shall leave as am! If you may prompt me how make that about what you wrote (it is desirable with an example of a code) I shall be very grateful to you.

When the user presses the Close button, the WM_CLOSE message is sent to the dialog box. Use the Class Wizard to add a handler (OnClose) for that message and you can write your code in there.

Very good, this works fine.

This disables the main windows close button.
How can I disable the close button form a child window,
say a open document in a mdi application?

Thanks for you help

Take Project-Settings and take the General tab

There will be a drop-down combo with the text "Microsoft Foundation Classes" above it.

Select "Use MFC in a Static Library" from the combo

Black bar showing up in edit and list view bug?

Hi everyone. I am sure others have encountered this problem, it came up often at my previous job, but I don't think we ever figured it out completely. I have a dialog based app, which reads data from a DAO database. The data is read in both into edit boxes and list views. Specifically, a list of data is shown in a listview, and a dialog with edit boxes etc appears when you edit or add a new record. Sometimes, mysteriously, instead of the given text being fetched out and displayed in the text box or edit box, all that is displayed is a single black bar (an ASCII character below 32 I imagine). This seems to occur totally randomly, I cannot recreate it this on purpose, but it can occur randomly. it seems to happen more with entries in the middle of the list view. I ahve done a lto of debugging, and it seems data is always fetched out of the DB okay, but it just doesn't appear properly.

The black bars are undisplayable characters. This is not a bug in CEdit or anything, your data simply contains unprintable chars. These are probably carriage returns or similar.

Try using multiline list boxes, or scanning your data for 0x0D, 0x0A

How do I get a file's complete path?

30-Oct-01 21:04

How do I get the full path and file name of a file, given just its file name or relative path? My program will accept one parameter, a file named passed on the commandline. I need to take the file name passed, and both get the file's full path and name, and in the process validate that the file actually exists.

eg. myprogram.exe somefile.mdb

Where somefile.mdb is a file in the same dir as the exe. I need the whole path of somefile.mdb. It can be not just in the same dir as the exe, it could be in any path specified,

eg. myprogram.exe ..\..\somefile.mdb

I searched through MSDN for a way to get the whole path, but did not find any way that actually worked. Anyone have any ideas? Confused | :confused:

It's not that clear what you're after exactly, but I think it's probably this:

Assuming that argv[argc - 1] points to the filename that you've got:

char strFullPath[MAX_PATH];
char *strFilename;

DWORD dwStatus = GetFullPathName(argv[argc - 1],
                MAX_PATH,
                strFullPath,
                &strFilename);

cout << strFullPath << "\n";
