One solution is SetItemState(). Pass in LVIS_SELECTED.

Hi,
There's some problem in MFC's documentation about CTreeCtrl::SortChildrenCB method. The parameters in the callback function are not handles to the tree items but the datas of the items..
My problem is my tree can have subfolders and when i sort i want subfolders reside on the top ( alphabetically sorted within themselves ) and the leafs under them ( again alphabetically sorted ). I distinguish the subfolder and leafs with their data ( leafs being 0 and subfolders being some positive values ). So i can use the parameters of the callback function to separate subfolder from leaf but i couldn't figure out how i could get the item's text so that i can sort them...
Any help is appreciated. Thanks in advance.

Are you using the data values for anything other than parent/leaf determination? If not, you can set the item's data to be its HTREEITEM, so you have full access to the item's properties in the callback. If you do use the data for something else, create a data structure containing the data you need, and set the item data to be a pointer to an instance of this structure.
Hope this helps,

Hi Ryan,
I use the data to figure out which item item is leaf and which item is subfolder. Your first proposal came to my mind too but i used the data values too often in the project that replacing them HTREEITEMs will require quite an effort to modify the whole project. And the subfolders under a parent folder have all the same data so i guess the only unique value left for me is the HTREEITEM.
I think i'll have to implement my own sorting function if i can't come up with a better idea on reaching to HTREEITEM using callback function.
Thanks for your reply.

Gabby,
You could always try www.sysinternals.com
http://www.sysinternals.com/ntw2k/info/defrag.shtml
This information is regarding the built in native support for disk defragmentation on NT and later.
The pointer also includes source code and examples.
Hope it helps

I've been working on a Phone Book program for a few days and have hit a snag on the graphical part.
I wanted 5 buttons with bitmaps (for home, mobile, work, ect) with text, to do that I would have to make them ownerdrawn, I did'nt want to go through the hastle of that.
I decided to make the buttons bitmaps, then when the mouse is over them change the styles to text to show the text.
I got that working fine but when you click the buttons (actually check buttons) they stay in there current state! When you mouse over the other buttons then come back to the one you just checked it works fine!
Here is the link to a zip with the source+workspace/exe http://www.kruncherinc.com/PhBk.zip
Please, any ideas?

Are you Invalidate()ing the window of the button who's state changes? The window will only redraw itself in response to a WM_PAINT message- perhaps the action of moving the mouse is triggering this.
There are loads of graphic/bitmap button classes here on codeproject that would probably suit your needs. Yes, you'll need to apply BS_OWNERDRAW to a button for it to appear properly, but these classes will handle all of the details for you.

Hi
I'm facing the following problem using AddFontResource function.
I've got Type1 fonts' files embedded in my programs resources. And I want make them(fonts) automatically install on programm startup and remove on programs shutdown. I'm doing the following:
1) extracting binary data from resources and saving them in temporary files
2) trying to add them by calling
AddFontResource("c:\\windows\\temp\\DIN-Bold.pfm | c:\\windows\\temp\\DIN-Bold.pfb");
But this function always returns 0.
The same procedure works well for single-file ttf fonts.
Could anybody help me to find out why it doesnt install pfm+pfb fonts.
I'll be glad to get any help from you.

I reckon there's a defect in MSDN - there should be no spaces surrounding the | character, i.e.
AddFontResource("c:\\windows\\temp\\DIN-Bold.pfm|c:\\windows\\temp\\DIN-Bold.pfb");You might have more luck with that.
Untested, but there are some examples on Google's groups archive.

I'm looking for a library that can convert ASCII, Multibyte and WideChar strings to and from different UTF encodings
- at least UTF-8 and UTF-16
- free (preferrably with source)
- fast
Any sources?

http://www.unicode.org/Public/PROGRAMS/CVTUTF/
From Unicode.org themselves
Handles UTF-8, UTF-16 and UTF-32.
There's also some UTF-7 code up there, if you care.
You can also use MultiByteToWideChar() and vice versa to do UTF8 and UTF16 conversions. See MS docs for the constants.

Wsaq.dwSize = sizeof(Wsaq);
Wsaq.dwNameSpace = NS_BTH;
Wsaq.lpcsaBuffer = NULL;
if(WSALookupServiceBegin(&Wsaq,LUP_RETURN_ALL ,&hlookup) == SOCKET_ERROR)

Have you imported "ws2_32.lib" ?

Hello,
I would like to know whether it is possible to listen to a specific EM_/EN_ message from CEdit informing the caret has been moved to a different position? Is there such a message? Or do I have to listen to the OnChar event and from there call GetSel(...,...) to know the caret position?
All comments are very appreciated,
David

Hi..
I have created some directories and sub directories using the Unicode function "CreatedirectoryW()" as the full path exceeds 260 chars..and it was succesful from the code point of view..
Though I created these when i decided to access them from windows I couldn't do so..It is throwing an error that "can't access this folder.Path is too long"..
If this is the case what is the purpose of Using Unicode function to create directories which exceeds 260 chars limit??
Is there anyway we can access these files???
Thanks
Sudhakar

You can access paths over 260 characters by adding "\\.\" to the beginning of the filename. Remember to escape the backslash.

Oh, well in that case there's absolutely nothing you can do about it. It is a limitation of Windows explorer. If you want them to be able to access it, you'll have to make the path names shorter.
