P.S. Depending on what version of comctl32.lib you are using, you may have to change MIIM_STRING to MIIM_TYPE to get main.cpp to compile - or just comment out the whole of CreateMenu() as it has nothing to do with my toolbar problem anyway. Any replies or help much appreciated! Many thanks, KB

You might try posing question #2 to the folks in the Access section at http://www.mvps.org/[^]. A rich person is not the one who has the most, but the one that needs the least.

Thank you for your reply, it's very encouraging. At first I was scratching my head to your answer to question 4, before I realised that SDI is just "Single Document Interface" (as opposed to MDI) - just the terminology can be daunting at first. :) Everyone seems to recommend the Prosise book, so I think I am going to splash out and buy both, so I can use Prosise's as a reference. Looking through the indexes (indices?) on Amazon.com I see that Prosise's book covers such things as RTF files and tree views, so I can turn to that once I've gone through the basics in Jones and am ready to take on the main aspects of my program. Thinking about your reply to no. 2, I have decided to go through some C++ basics before looking at these books though. I have just bought a very nice and cheap book called "Teach Yourself C++ in 10 minutes" (somewhat ridiculously) by Jesse Liberty. I've started going through it and I really like it, as it recaps on the basics of C and then moves into very short (supposedly 10 mins each) lessons on C++ - OOP, classes, etc. I like it because it means I can grasp the bare basics of some of the C++ concepts without having to wade through 1,000 pages (nothing worse than slogging through a book and thinking "I'm not going to learn how to use a class until page 600, and I'm a slow reader..."), and I can refer to my other C++ books with a more need-to-know approach after I've got some of the concepts (and terminology - one of the problems of being self-taught) pegged. It's very encouraging to hear that someone else has taken a similar route when learning MFC. Thanks again, KB

OK, I'll bite; it's not like I was busy or nuffink. A tree view item can have an arbitrary piece of data associated with it. This is not predefined or limited to what it can be (outside the fact it's an LPARAM in size). This means it can be the index in an array of CStrings, or a pointer to a CString, or anything you want it to be. When you select a tree item, you can then ask what it's data is, and use that as the basis for locating/displaying. There's a caveat. You might need to manage the freeing of such data when items are deleted from the tree, either all at once, or one at a time. Experiment in DEBUG mode if you're using MFC and you'll find out if you've new-ed without a delete, although reading the documentation could tell you as well ;P Steve S

Great, thanks for the info, and thanks for the replies to both of you. In the end I went the EM_GETTEXTLENGTHEX route and used that to create the buffer, though I had problems before realising that I needed to load RichEd20.dll instead of RichEd32.dll, and then, because I was using a dialog-based app, I had to manually change the class name in the .rc file to "RICHEDIT20A" instead of "RICHEDIT" (just in case anyone else encounters this problem). Thanks again! KB

Could it be a permissions issue? Are the files on an NTFS volume? Five birds are sitting on a fence. Three of them decide to fly off. How many are left?

Brilliant, thank you! Both suggestions work great, but I've used AdjustWindowRectEx because it requires less code... Thanks again, Keith

Something is amuck with your link. It has embedded tags in it. Try http://www.codeproject.com/script/comments/forums.asp?msg=626506&forumid=1647#xx626506xx[^] instead. Five birds are sitting on a fence. Three of them decide to fly off. How many are left?

i would think u have to save the path names of the selected files along with the hierarchy info ... the tree view is only holding refs to those things in effect anyways u should consider saving to an xml file as it is designed to represent hierarchical data after all :) "there is no spoon" biz stuff   about me

Take a look at the SetWindowLong function in the Microsoft SDK documentation. This function will allow you to set a new wndproc (GWL_WNDPROC) which is what is meant by subclassing. When you change the wndproc all messages will come to your new wndproc...messages you do not handle should be sent to the original wndproc. You should probably be able to find actual example code by searching msdn as well as information regarding subclassing...there is an article called 'Safe subclassing in Win32' that may get you started http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwui/html/msdn\_subclas3.asp

Hi, Okay, I found this article on MSDN that discusses this problem: http://support.microsoft.com/default.aspx?scid=kb;en-us;130691 Unfortunately I'm relatively new to coding C++, and I don't know how to go about implementing the advice given in that article. From the article: "To work around this problem, subclass the edit control in response to the TVN_BEGINLABELEDIT notification that is sent by the tree view control when the tree view is about to start label editing for an item. To obtain the edit control's window handle, send the tree view control a TVM_GETEDITCONTROL message. The subclass procedure should handle the WM_GETDLGCODE message by returning DLGC_WANTALLKEYS. This allows the tree view's subclass procedure to handle ESC and ENTER keystrokes." So, if I understand correctly, I need to subclass my tree view control here: //EDIT LABEL: if(((LPNMHDR)lParam)->code == TVN_BEGINLABELEDIT) { hEdit=TreeView_GetEditControl(hTree); //subclass here??? } If anybody could tell me how to subclass this and handle the WM_GETDLGCODE message accordingly, I would be very grateful. (_NON-MFC_ :) ) Sorry if this is a really basic question. Many thanks, KB

Thanks! That is exactly what I needed. I found a function using that API call along with LB_SETHORIZONTALEXTENT here: http://www.catch22.org.uk/tuts/dirlist.asp that does exactly what I needed, with a few minor qualifications. Thanks again, your help is much appreciated, KB

Ah, figured it out. I just use RegQueryValueEx to get the value of PendingFileRenameOperations when the program starts. If it returns ERROR_SUCCESS, I just replace the changed value with the saved value when the program ends using RegSetValueEx, otherwise I delete PendingFileRenameOperations using RegDeleteValue(). Thanks anyway, KB

Kayembi wrote: ...but I don't know how to set up the callback function. It has the following signature: int CALLBACK CompareFunc(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort); The MSDN article Q170884 should give you some ideas, even though it's in VB. Basically, each item that is added to the list control has an associated item data (use the LVM_SETITEM message for this). When CompareFunc() is called, lParam1 points to one item's data and lParam2 points to another item's data. You have to cast lParam1 and lParam2 to the appropriate type, and then do some sort of comparision.

Thank you both for the replies, much appreciated. The only reason I'm not using MFC is that as a relative coding novice, I haven't really touched it yet - I need to buy a book on it and dive in soon, I know. :) Also, the rest of my program has been written without MFC, as it started off as a fairly straightforward dialog app a year or so ago. Now that I'm updating it, though, it's getting a lot more complicated, but I'm reluctant to rewrite the whole thing in MFC because of my inexperience and the amount of time this would take (re-learning how to do everything I've already coded + coding it). Many thanks again for the help! Cheers, KB

Thanks for the replies, much appreciated. Does this mean that if I created an owner-drawn menu instead of creating one in the dialog editor, it would show correctly? (That is, if it is okay to mix an owner-drawn menu with a dialog-based app...) Many thanks, KB
