Re: How do splitter depend on window styles? Tomasz Sowinski19-Jul-01 5:25 Tomasz Sowinski 19-Jul-01 5:25  When your program ASSERTs, open the 'Call stack' window. From the main menu select View/Debug windows/Call stack. There's also an icon on the toolbar.

I need help please!! sophian Re: hit testing Tomasz Sowinski19-Jul-01 3:23 Tomasz Sowinski 19-Jul-01 3:23  What exactly is your graph? You have a table of points and graph is a collection of lines connecting p0 with p1, p1 with p2 and so on?

Combo list Gérald Mercet19-Jul-01 2:43 Gérald Mercet 19-Jul-01 2:43  I would like to know how use the instructions switch, case... with a combo list. I explain it: If i have names in the combo list, and for each name i want to do different actions, for example just create specific afxmessagebox for each name. I know that the better way to do that is to use the switch command, but as it take only numeric expression how could i solve it? gerald Re: Combo list Bret Faller19-Jul-01 13:15 Bret Faller 19-Jul-01 13:15  You can use SetItemData(nItem, dwData) for each item in the listbox/Combobox and then you can do a switch statement using the GetItemData(nItem). In order to make this more efficient you should setup an enum of the values will always be the same. Here's a question though... Are you just trying to get the text of the Item and display that in a messagebox?

When I include <afxcmn.h>, to use the treecontrol, I get the following error: LINK : fatal error LNK1104: cannot open file "nafxcwd.lib" It's damn right, because the file does't exist. And it isn't on the cd either, as the help file tells me. What the? WAVK damn tags, here's the include file I ment 19-Jul-01 2:34 19-Jul-01 2:34  afxcmn.h Re: treecontrol again Tomasz Sowinski19-Jul-01 2:46 Tomasz Sowinski 19-Jul-01 2:46  You're trying to link MFC statically - nafxcwd.lib is a static MFC library, debug version. It seems you're using 'Standard Edition' of VC++ (formerly known as 'Learning Edition'). This version doesn't support static linking to MFC. There's an interesting article somewhere on CodeProject dealing with this.

Richard Dialog in Bho Winston,Dang19-Jul-01 0:43 Winston,Dang 19-Jul-01 0:43  I create a toolbar in the Internet Explorer.When I click one button on this toolbar,I want to show a modal dialog.I use following code in the toolbar's button click events. CMyDialog dlg; int ret=dlg.DoModal(); I get ret=-1. When I create the dialog in the Band.cpp file and make the "dlg" as a global variable, then in the click event I use dlg.ShowWindow(SW_SHOW), It will show the dialog modaless.Now another problem is out.I can't use the "TAB" key to change focus between the controls on the Dialog Box. What's wrong with it?

The Problem is everytime I do dlg.DoModal(); the String reset's to NULL! Maybe someone can help me! Thanx Enzi Re: Transfer Data from a List to a new Dialog Peter Pearson19-Jul-01 1:13 Peter Pearson 19-Jul-01 1:13  Hi, The easiest way is to create a member variable CString (or whatever) in each dialog. Then when you've got the string you want from the list, call: CMyDialog dlg; then: dlg.m_strString = strList; where m_strString is the member variable for the string in the second dialog and strList is the string that holds the value from the list box. Then you can call: dlg.DoModal(); In the second dialog you can no do what you want with m_strString. Cheers, Peter Re: Transfer Data from a List to a new Dialog Enzi19-Jul-01 1:18 Enzi 19-Jul-01 1:18  Ahh thanx! So if u understood right. For each variable I want to use in Dialog2 from Dialog1, I've got to make a Variable in the ckass of Dialog2. Ok thanx for the help! btw Windows Programming is complicated!! Enzi
