Got your point. I understood how a CString object works especially when used in cout. But for now, since I'm in a hurry, I'll use printf for the moment.

hi all
i want to set a buttons background color . i tried WM_CTLCOLOR message.
it works properly for the EDITs and sets their background. but when i use it for buttons , its color doesnt change.
does somebody know how to change a PUSHBUTTONs background color??

According to Microsoft, the WM_CTLCOLORxxx approach works for list boxes, the list boxes of combo boxes, button controls, edit controls, static controls, message boxes, and dialog boxes but does not work for push buttons and the CRichEditCtrl. The color of a standard CButton object is determined by system settings. If you want a different color for push buttons, use a CBitmapButton. To change the color of a CRichEditCtrl use its member functions.
So be it

You can create your own class of buttons using control subclassing , where you will be able to change text color and bk color very easily.

When I create the MFC dialog application (with the manifest generation enabled) my dialog should use the XP visual style common controls, right?
Well, it doesn't! Is there anything else I have to do?

See this[^] MSDN article on how to enable XP visual styles in your VC6/VC7.x generated app.

Can anyone please tell me why this code code gives a segmentation? The
class NonLeafTrieNode
{
public:
NonLeafTrieNode(){};
NonLeafTrieNode(char);
private:
friend class Trie;
NonLeafTrieNode **ptrs;
char *letters;
int endOfWord;
bool isLeaf;
};
The code below are in the Trie class and I use this to access the isLeaf variable in the class.
int flag = p->ptrs[pos]->isLeaf;
if (!(pos == -1) && flag)
If I keep the isLeaf variable a boolean the code gives a segmentation fault, but whenever I make it a integer the code works perfectly.
Can anyone tell me why this happens.
Thanks a lot

The implication from your code is that -1 is a possible value for pos. In that case, p->ptrs[pos] is never going to work...

flag is an int and you are trying to assign a bool to it. When you change isLeaf to an int the types are the same.

On Sep 22 I put up this query, but without getting any answer:
I have the webbrowser in a program but want also to access the equivalent of this functionality:
internet explorer: Tools/internet options/general/fonts/language script
I expect it is not something exposed in the webbrowser, but otherwise.
Does anyone know how it can be done ?
SINCE then I have found how to do it, and since it is relatively straightforward, I am surprised not to get any answer.
The solution is given in the Microsoft book, Programming the Internet Explorer.
It all hinges on the lines:
hr=lpDispatch->QueryInterface(IID_IOleCommandTarget, (void**)&lpOleCommandTarget);
hr=lpOleCommandTarget->Exec(pguidCmdGroup,nCmdID,0,NULL,NULL);
where nCmdID =3 if you want the Internet Options.
If you are interested you will find all the details in the book.

Thanks for your post, Raymond. Is this[^] the book to which you're referring?

Yes, that's it:
Programming Microsoft Internet Explorer 5 (Microsoft Programming Series) (Paperback,)by Scott Roberts
The material you need is on pp.259-262.
Although the book was written for IE5, and I am now using IE6, and Visual Studio 6 & 7, the code does not need to be changed, not even the GUID for CGID_WeBrowser.

How can I redraw the full screen (all the windows)?
|
|
|
|
|
i guees you are talking of invalidate,or then go for GetDesktopWindow()(desktop handle) then invalidate that,i havent done its just a guess ,if you mean one from program then just invalidate().
|
|
|
|
|
Thanks for the response.
Unfortunately it didn't work 
The reason I need to erase/redraw/invalidate everything is becouse I am drawing on the screen DC (GetDC(NULL)) but at the some point I want to revert changes.
I guess enumerating all windows and invalidating the visible ones could work but I tought the might be a better way...
|
|
|
|
|
InvalidateRect(NULL, NULL, TRUE) will invalidate all windows.
Now I need something like UpdateWindow or RedrawWindow, but for all windows.
