Re: TreeView and ListCtrl Steve Driessens19-May-01 3:48 Steve Driessens 19-May-01 3:48  G'day, How about implementing a vertical splitter window and putting a tree control view in one pane and a list control view in the other? Then handle item selections in the tree and notifying the list view so that it's contents are synchronized with the tree. There may be a better way of handling this, but that's the best I can come up with for the moment. Hope this helps, Steve Re: TreeView and ListCtrl BLaZe19-May-01 4:16 BLaZe 19-May-01 4:16  Yes thank you but do you know where I can find Source or do you have a little BASIC program (exemple) for demonstrate this because I'm not very familiar with the Handle of a Tree TIA BLaZe BLaZe ICQ # 110244345 email : mpblaze@iquebec.com Re: TreeView and ListCtrl l a u r e n19-May-01 3:53 l a u r e n 19-May-01 3:53  make a new project ... choose an sdi app ... choose a windows explorer style app ... change the right view base class to be clistview ... compile ... voila --- "every year we invent better idiot proof systems and every year they invent better idiots" Re: TreeView and ListCtrl BLaZe19-May-01 4:15 BLaZe 19-May-01 4:15  Yes thank you but do you know where I can find Source or do you have a little BASIC program (exemple) for demonstrate how to change the ListView TIA BLaZe BLaZe ICQ # 110244345 email : mpblaze@iquebec.com Re: TreeView and ListCtrl l a u r e n20-May-01 3:14 l a u r e n 20-May-01 3:14  how to change the listview? you mean update it on an event? thats all in the docs and is very straightforward ... as for a basic example program with code ... thats what the app wizard gives you ... look thru the code it generates to at least see what is going on --- "every year we invent better idiot proof systems and every year they invent better idiots" How to handle a file which might over 4G? 19-May-01 2:18 19-May-01 2:18  Hi, I need to write a large amount of data into a file, but the limitation of a file under windows is 4G. How can I handle this situation safely? Thanks. Re: How to handle a file which might over 4G? l a u r e n19-May-01 3:48 l a u r e n 19-May-01 3:48  write the file into a sequence of numbered sub-files (i would include a file header of my own design that kept the name of the file sequence and the sequence number safe inside) the sub-file size would depend on how you have to read it back in but i would consider maybe 20mb to 50mb blocks ... its still going to be a real bore for the folks waiting to load even a portion of the overall file but its better than waiting for the whole thing to arrive in memory you do of course have a machine with vast amounts of ram and virtual memory i assume or loading in is a real no-no --- "every year we invent better idiot proof systems and every year they invent better idiots" RtlFreeHeap Error 18-May-01 23:41 18-May-01 23:41  When I execute program under debugger I receive message: HEAP[aaa.exe]: Invalid Address specified to RtlFreeHeap( 1c50000, 1608938 ) But visual problems with pointers doesn't exist. Can you advice me something. Re: RtlFreeHeap Error l a u r e n19-May-01 3:50 l a u r e n 19-May-01 3:50  in my experience this usually means you have allocated some memory blocks and either over or underwritten the allocated space ... check you don't exceed the amount of memory you allocated --- "every year we invent better idiot proof systems and every year they invent better idiots" Re: RtlFreeHeap Error 19-May-01 5:41 19-May-01 5:41  You may want to verify mixed libraries in your linkage - debug and release builds. The memory allocated in debug builds has some additional space that does not exist in release mode (see for ex, help _calloc_dbg in MSDN). The solution then is to link only the same builds of your libs (either debug or release). Exporting Dialogs having ActiveX controls 18-May-01 20:29 18-May-01 20:29  I have developed a regular DLL which contains dialog resource, having ActiveX control along with other windows controls. I have exported a function which calls DoModal function on that dialog. But when I call this function in another application ( using explict linking - LoadLibrary..) it does not display the dialog box and returns -1 . It works fine when there is no ActiveX control.

Toolbars in Rebar Control grayed out Juan Miguel Venturello18-May-01 12:53 Juan Miguel Venturello 18-May-01 12:53  Well I have been at it for some time, searched the newsgroups and all, but in the end found nothing. I create my toolbars with this call: g_hwndTB[j] = CreateWindowEx(0, TOOLBARCLASSNAME, (LPSTR) NULL, TBSTYLE_TOOLTIPS | TBSTYLE_FLAT | CCS_NODIVIDER, 0, 0, 0, 0, hwndParent, 0, g_hInst, NULL); j is the specific toolbar, this is a loop creating each toolbar in sucession. I add the bitmaps, the buttons, etc. Then I create the rebar: HWND hwndRb = CreateWindowEx(WS_EX_TOOLWINDOW, REBARCLASSNAME, (LPSTR) NULL, RBS_VARHEIGHT | RBS_AUTOSIZE | RBS_BANDBORDERS | RBS_DBLCLKTOGGLE | RBS_REGISTERDROP | RBS_VARHEIGHT | CCS_NODIVIDER | CCS_NOPARENTALIGN | RBS_VERTICALGRIPPER | WS_BORDER | WS_CHILD | WS_CLIPCHILDREN | WS_CLIPSIBLINGS | WS_VISIBLE, 0, 0, 0, 0, hwndParent, 0, g_hInst, NULL); After this I insert the bands as follows: REBARBANDINFO rbbi; rbbi.cbSize = sizeof(REBARBANDINFO); rbbi.fMask = RBBIM_COLORS | RBBIM_CHILD | RBBIM_CHILDSIZE | RBBIM_STYLE | RBBIM_ID | RBBIM_SIZE; rbbi.clrFore = GetSysColor(COLOR_BTNTEXT); rbbi.clrBack = GetSysColor(COLOR_BTNFACE); rbbi.fStyle = RBBS_NOVERT | RBBS_CHILDEDGE ; for(int i=0; i How can I get text under mouse pointer? 18-May-01 9:40 18-May-01 9:40  Hi !

Jim A. Johnson18-May-01 8:05 Jim A. Johnson 18-May-01 8:05  I've stumbled into a nasty limitation of tree controls. I need to build a tree control that uses images from the system image list as well as my own custom images. (One branch of the tree will reference file objects in the system, and the other will reference my own objects.) I initially tried to do this by copying the entire system image list to my own image list, but alas, the system image list is dynamic, and may not have a particular icon in it unless I specifically request it. Well, I can't do tht on initialization, cause I don't know which icons I may need. So now I'm looking at storing handles to the icons (along with other info) in the LParam for each tree node, and then using custom draw to draw the icon. However, this seems kludgy, and I'm not sure it's the best approach. Does anyone have suggestions? TIA Re: Tree Controls _without_ image lists? Tomasz Sowinski18-May-01 8:15 Tomasz Sowinski 18-May-01 8:15  I'd set the item image index to I_IMAGECALLBACK and handle TVN_GETDISPINFO. Tomasz Sowinski -- http://www.shooltz.com.pl Re: Tree Controls _without_ image lists? Jim A. Johnson18-May-01 9:25 Jim A. Johnson 18-May-01 9:25  Thanks, but I don't think that will help; it still makes use of the images in the control's image list. That's the problem: not the fact that I can't reference images in the list, but the fact that I can't even build the imge list. Re: Tree Controls _without_ image lists?

You can play with custom draw, but I think it would be easier to use the control's image list as a 'icon cache'. When TVN_GETDISPINFO is processed, you can add the icon to imagelist before returning from message handle - sort of 'delay loading' for icons.
