OK, that shows that you're creating a managed object. Don't delete it, the CLR garbage collector will take care of that for you. The reason you don't need __gc in the declaration is the compiler infers it from the context - Hashtable is a managed object so __gc is the only possibility.
Yes, this is confusing and it's the main reason why the MC++ syntax was replaced with C++/CLI in VC8.

Thanks for all of the helpful information.
As I understand it now, the way my project is setup, the hashtable is a managed object, so I can't delete it mannualy, (as I get errors when I try).
So my follow up question is this: If I store an object that was declared with a NEW, and store it in the hashtable, do I need to go back through the hashtable and delete those objects, or does the managed code do that as well?
Example:
MyObject *tempObject = new MyObject;
Hashtable *hashObjects = new Hashtable;
hashObjects->Add(key, tempObject);
So if I store several tempObjects in my hashtable, do I need to traverse through the hashtable and DELETE the tempObjects, or does the garbage collector handle this as well as the hashtable itself?
If I do need to delete them, will a call to hashObjects->clear(); delete the objects?
Thanks,
Jody Blau

I create a button at runtime using CButton.Create() function. The button looks fine until it is clicked the first time. From then on the black rectangle around the button becomes slightly wider and does not go away with releasing the button.
It's cosmetic problem only, subtle but annoying nevertheless.
I suspect it's something to do with window-style and extended-window-style but I had no success so far.
Thanks in advance for your suggestions.

Could it be focus rectangle drawn to the Button, Did you try taking the focus off the button, like pressing the Tab button.

If you are trying to use a push button, then make sure you put style as BS_PUSHBUTTON.
You can also try, SetState(FALSE);, which will remove any highlighting

The extra-dark border marks the default button. If more than one button has the BS_DEFPUSHBUTTON style, that will muck up the dialog manager and buttons will be drawn incorrectly.

Laugh it up, fuzzball.

that was it ! I just added a line of code in the BN_CLICKED message handler to remove the "BS_DEFPUSHBUTTON" style. The trouble was that multiple buttons showed this dark outline which looked goofy.
Thanks

I have a MFC MDI App, to which i have added new CDialog. Now when i pop-up the new dialog from MDI and use the controls in it, it will be using the main thread of the MDI App.
I wanted to make this new dialog run on a new thread, so that all controls in it will run on new thread and the MDI will have its main thread always free from dialog. Can anyone tell me how to do this?
Thanks

You need to create a UI Thread in MFC, check CWinThread for more info. You can then start your dialog in this thread.

do u have an idea of getting the filename from the handle returned by the FirstFindChangeNotification.

FindFirst/NextChangeNotification() don't work on files, they watch entire directories. You have to figure out on your own what changed.
You can use ReadDirectoryChangesW() to get more details change details.

I would like to implement a custom caption bar with CLose, Min and Help buttons. The framework does not allow this. Any suggestions

in WM_NCPAINT to draw it your self.
if you want different shape of caption bar, you need to draw more.

Thanks for the reply.
I have hooked my CMainFrame wnd in line with a project by Paul DiLascia. In the new window process I am responding to several messages. I found that in order to display the correct tooltips I had to trap WM_NCHITTEST and where it was over my new Minimize button (original Maximize button position) return HTMINBUTTON instead. However when my new Minimize button is pressed, my new Help button is overwritten with a pressed Minimize button.
It all appears to be happening in the Default window proc.

I'm constantly moving my laptop around to different networks, and at each place I need to change the static IP settings. I'm writing a little utility to store my various configurations and set the appropriate one when needed.
Right now I'm changing the IP settings from a batch file with the "netsh interface ip set..." command. Obviously, this is an ugly way to do it, but it works. This also makes it more difficult to add/edit my various listings.
I'm looking for a more elegant solution... and suggestions?
Thanks for any help -mutty

Using VC6 on Win2K:
Given the following code:
DWORD dwFlags = OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT|OFN_ENABLESIZING;
CString sFile = _T("");
CFileDialog dlg(TRUE, "rc", NULL, dwFlags, "Resource Files (*.rc)|*.rc||");
if (IDOK == dlg.DoModal())
{
sFile = dlg.GetFolderPath();
}
The dialog displays, and allows me to select a file, but it asserts when I click OK.
The code is very simple and straightforward, but I get a debug assert in dlg.GetFolderPath() claiming the hwnd for the dialog is NULL. Can anyone tell me what I missed or did wrong?

After DoModal, calling CFileDialog::GetPathName returns the file path.

I don't think you understood the question.
Why does calling GetFolderPath() assert?

because it sends CDM_GETFOLDERPATH to the dialog window, which does not have a valid window to recieve it anymore.
