I hate the MFC group box. It's such a pain to use most of the time. Sometimes, depending on the order of creation in the resource file and making sure your tab stops and group stuff is checked correctly, you can't get your radio buttons to show up. That gets me every time. Grrrr.
Also, why can't you actually GROUP your controls with your group control?!?! Let's say my application is divided up into sections of group labels. (I'm not claiming it's pretty.) If I wanted to temporarily disable all the controls in a group it sure would be easy to just have to disable to group control. This is a feature I'd LOVE. Come to think of it, maybe that might be pretty easy to do...
Well, also Microsoft's dialog editor... Why can't I group some controls together, select them all, and actually cause them to behave like a group, even when dragging them around on the screen.

Some great ideas! Now if only Bill Gates would agree to implement them (which I doubt). Maybe you or someone
could write a new group control to do some of these things.

Well, you have to realize that MFC is only using the standard windows Group box. This is just a button control, that draws itself differently. Thus, it is dependant upon all the characteristics of other button controls and cannot itself have child controls (well not easily).
Other languages, like VB provide what you're asking for, but they have created their own controls for this versus using the standard windows ones. Microsoft doesn't usually provide anything more than wrappers around existing controls (with a few exceptions, like CCheckListBox).
In any event, MS couldn't deprecate the existing group box, but they could just as easily create a new one. Though you could just as easily create one as well.
As for the dialog editor, you can most certianly select groups of controls and manipulate them as a group. Just use shift or ctrl while clicking.

Is it possible to intercept all input from users before Windows sees it? I want to disable Ctrl-Alt-Delete, Alt-F4, and other user inputs in certain situations. I'm writing a security app for Windows 9X systems to help some teachers control their computers. I think you can do something with .vxd files, but I'm not really sure what they are or where to start looking. Can someone help me out?

You may want to look at using CBT hooks.

Would you happen to know of any example code for CBT hooks? I've looked at MSDN and I was unable to find some examples.

This is a long shot, but I am looking for a way to view HTML pages as if in a browser, but not using MFC, and definately NOT using Internet Explorer.
Just to really push the possibility of an answer, I would prefer to be able to use it from/in 'C' code (nnot C++).
Am I dreaming, or is this possible?
Thanks for any help,
James Millson

The man you need to contact is Russ Freeman. He has several web sites but the one that I can think of right off hand is http://www.gipsysoft.com
He has a product that is called QHTM. He is currently not pushing it because he has bigger and better things but if you email him about he will give you some info on it. There is a freeware version on www.codeguru.com and he has a version that is updated with many new features.
Tell him that Rodney at MediaVergence Group referred you to him.
Another option would be wxWindows 2.

I want to create a dialog but have it hidden right from the beginning and open it at a later time with ShowWindow()
|
|

It's really pretty simple, though. Just create your dialog with the editor. Let Class Wizard make your classes for it like normal. I imagine you'll be showing/hiding from your main app, so if, say you were a dialog based app, simply include your header for your hidden dialog(s) in the header for your main dialog and make a member or two:
CHiddenDlg* m_pHidden;
Now assuming your resource ID for the hidden dialog is IDD_HIDDEN_DIALOG, in the CPP of you main in OnInitDialog just do this:
m_pHidden1 = new CHiddenDlg(this);
m_pHidden1->Create(IDD_HIDDEN_DIALOG, this);
Then, whenever you want to show/hide just use
m_pHidden1->ShowWindow(SW_SHOW);
m_pHidden1->ShowWindow(SW_HIDE);
Make sure you clean up at the end and you'll want to be a little better than I was about checking that your dialogs got created and all that.

In MFC, do you know how to launch the Internet Explorer .exe and then open the URL and then download the html from this URL?
Thanks a lot for your help!!

Is that I need to use CHtmlView?
What's the procedure to use the MFC internet class and it's function? I'm sorry that I'm a new programmer in MFC, I'm know a little about it.
Thx for your help!!

Look for CHttpFile in your documentation:
"... The class CHttpFile provides the functionality to request and read files on an HTTP server ..."

Thx a lot!!
I've downloaded the source code of the URLdownload and WebGrab! It seems quite useful for my project! I will take a look within these days! Thx again!

There is yet another way.
Look up the article "Internet Downloading Using Asynchronous Monikers". Deriving a class from MFC's CAsyncMonikerFile class is a very easy way to get a URL off the net.

Hi Milke,
I have tried to build the exe from the source code of URLdownload, however, it shows there is a link error "mfc42ud.lib". I just know it is a unicode library but how can I fix this error? Otherwise, I can't trace the flow of the program.
Looking forward to your reply! Thanks a lot!!
Regards,
Dig

You're building the Unicode debug configuration, but you didn't install the Unicode files when you installed VC. Switch to the (regular) debug build instead. If you really want the Unicode build, you'll need to rerun the VC setup and install the Unicode libraries.

Is history an illusion caused by the passage of time, or is time an illusion caused by the passage of history?

Thanks Micheal.
However, I get another question.
You are using worker thread to handle the downloading process in the program, however, you declared that this is not good. Then do you know how to avoid using thread to handle the downloading process?
Thanks for your valuable advice!

No, what I did wrong was pass a CWnd object between threads. The proper way to do it is to pass the dialog's HWND between threads. From the worker thread, you can then do the UI updates with SendDlgItemMessage() calls.

What I got from your sentence is that it was not good to pass the pointer "this" in the pParam, right?
If I want to do the handle passing properly, is that I need to change the pParam to this->GetSafeHwnd()? Besides, what I need to modify in the related functions apart from this?
pWorkerThread = AfxBeginThread ( gThreadProc, this,
THREAD_PRIORITY_NORMAL, 0,
CREATE_SUSPENDED );
I am sorry that I am a beginner in Visual C++ and MFC so that I need to ask such kind of question! Thanks for your advice a lot!

In the worker thread (specifically CCallback::OnProgress()), you'll need to update the UI (progress bars, static text controls) with SendDlgItemMessage() instead of calling the ProgressUpdate() function in the dialog class.
Alternatively, you can package up the info sent to ProgressUpdate() into a struct, and send a custom window message to the dialog. The dialog's handler would read the data from the struct and update the UI.
