You have missed 4th parameter of HtmlHelp. Can you tell me what to give here when using HH_HELP_CONTEXT command. I am giving mapid but getting this message
"HH_HELP_CONTEXT called without a [MAP] Section."
Any remedy to this?

Now instead of using HH_HELP_CONTEXT, I am doing this
<br />
::HtmlHelp(NULL, <br />
"C:\\MyHelpFile.chm::/Welcome.htm>MyWindow",<br />
HH_DISPLAY_TOC,<br />
NULL) ;<br />
I am achieving my purpose. But tell me is it the right way instead of
HH_HELP_CONTEXT.

I've tried to put background image into CListCtrl, but i completely ran out of ideas how to do this!!!
I cannot use owner drawn control because I need big icons.
I cannot use CListCtrl::SetBkImage() because it cannot stretch bitmap;
Maybe this is done somehow by using custom draw, but I failed. Can somebody give me link to working sample with background image?
Give me any suggestions!

when you OnSize, dynamically resize the bitmap to the client area rect, then CListCtrl::SetBkImage(), there are good chapters on bitmap manipulation in Charles Petzold's programming windows 95 and Programming windows with MFC by j. procise

There's a special UI tool in O'reilly's "Win32 API Programming with Visual Basic" on the compliment CD, that lets you grab any child window's handle by clicking on it.
You could get that book, then use the tool on the CD to get that class tree control's window handle, and view it's messages. It no doubt sends notify messages to its parent.

I'm relatively new at SDI programs (and I haven't touched MDI yet), but I have worked with MFC dialogs a lot. It would be convenient to be able to create a dialog resource (probably one without a frame) and then be able to use that as my view. Is this possible to do? If so, how would I go about doing this?
If this is not possible to do, where would I create windows such as CButtons and CEditBoxes? I tried doing this in the OnPaint function, but I just get flicker. Thanks for any help you can give me!

If you want want to use a dialog as your main view either use AppWizard to create a dialog based application or, if you really want an SDI app, in the final stage of AppWizard change the base class of your view class to CFormView.
OnPaint is called every time the window needs redrawn, so is not the place to create controls. You could overload the Create method for the view and create them there.
You probably should get hold of a book on MFC programming - I found an earlier edition of this one very useful when I was learning the basics (I still refer to it a lot).

Why not create the controls through the recource editor and hard code them in your class or use the appwizard for creating controls!
I prefer hardcoding all controls.

A professor knows a lot about little.
I know everything about nothing.

Hi,
I have many dialog boxes in my application, and I need to transfer the data to another dialog box, in other words how do I access the data stored in a variable in a dialog from another one.
Hope my question is quite clear,
Thanks

One solution is messages. Send a message to the parent window and have it dispatch does the data transfer.

when you want to access a public member variable of dialog A from dialog B just do that:
((CDialogA*)GetParent())->m_member_variable = ...
in case of CDialogA being the parent of dialog B

Dear Friend
I used file operation method to get a grip with communication port and as it's my first time I've lots of problem and couldn't continue so...
I'd be appreciated if you could advise me
Regards

NULL, // no security attributes

0, // not overlapped I/O
NULL // hTemplate must be NULL for comm devices
);
if(m_hComPort == INVALID_HANDLE_VALUE)
{
// Handle the error.
CString str;
str.Format("CreateFile failed with error %d.\n", GetLastError());
AfxMessageBox(str);

// Handle the error.
CString str1;

AfxMessageBox(str1);
return FALSE;
}
dcb.BaudRate = CBR_9600; // set the baud rate
dcb.ByteSize = 8; // data size, xmit, and rcv
dcb.Parity = NOPARITY; // no parity bit
dcb.StopBits = ONESTOPBIT; // one stop bit

How can I get Hyperlinks into a CTreeCtrl?
I need individual items of the tree to function and look like hyperlinks.
Thank you,
XP
|
|
|
|

you probably won't like my answer
you can add the normal, non-linked url text to give the tree items the propersize, then cycle through them and get each of their rect bounds for the ones you want to hyperlink, then make an instance of 1 Subclassed CStatic over each TREEITEM bounds rect. (CStatic subclassed with the mouseover(trackmouseevent) and cusor change, + notify OnPressed + MAPPED function in parent, to the parent for the link)
for (int i=0; i

Better find an example of a custom-draw treeview control and customize it to display blue underlined text. To make the mouse cursor behaving as on hyperlinks you'll need to invent detection of where the cursor resides at each moment it is under the control (there is a simple WinAPI function that reports if the mouse cursor is under the text, or icons, or white space) and use a timer to detect OnMouseLeave. 2-3 day of work, probably

Hi all
why does this mean?
(CTestDoc*)m_pDocument;
Thanks
|
|
|
|
|
just like that ? no context ?
it simply means that the m_pDocument (that must be a CDocument class) is casted into a CTestDoc class.
meaning that the variable will be "seen" as a CTestDoc instead of the generic CDocument base class.
