Re: how to add Mouse Buttons in C++.NET Xander803-Jun-03 2:47 Xander80 3-Jun-03 2:47  Select the resource (dialog) where you want to add the mouse buttons to, in your resource view. Right click on the resource in the right document view. Select properties from the pop-up menu. A new window appears, click on Control Events in the toolbar. This shows all events for all the controls in your resource. CFormView key control doctorpi3-Jun-03 2:26 doctorpi 3-Jun-03 2:26  Hi guys What's the method to control a key pressed when we are working with a CFormView? I've tried OnChar but when the key is pressed the method is not called. Best Regards Dr.Pi Re: CFormView key control Rage3-Jun-03 3:40 Rage 3-Jun-03 3:40  OnKeyDown() ? ~RaGE(); Re: CFormView key control doctorpi3-Jun-03 4:13 doctorpi 3-Jun-03 4:13  I have the same result as with OnChar Maybe I'm doing something wrong, and it's a silly mistake. Thanks anyway Dr.Pi Re: CFormView key control Roger Allen3-Jun-03 6:11 Roger Allen 3-Jun-03 6:11  Your best chance is probably PreTranslateMessage checking for pMsg->message == WM_KEYDOWN and pMsg->wParam == VK_key_of_interest You can also make use of GetFocus() to check which control the input would have been aimed at.

Happy programming!! Re: Using IDiscMaster and related objects FlyingDancer3-Jun-03 2:34 FlyingDancer 3-Jun-03 2:34  Maybe you can find some infomation from some books about Windows API function. LeonOrient Scroll Bars in List control Prasanna_b_r3-Jun-03 1:21 Prasanna_b_r 3-Jun-03 1:21  Hello. Is there a way that the Horizontal Scroll Bar in a list control is always shown. It should be disabled in the size of all the columns is less than the control width and should be enabled if the size of the columns is more than the control width.

Are you aware that you are asking for something and for exactly the opposite thing ? Check the properties of your ClistCtrl when rightclicking on it in the resource editor, here you can enable Horinzontal Scroll Bar, which has them always shown, or Auto Horizontal Scrollbar, which describes the second way you have mentioned. ~RaGE(); Re: Scroll Bars in List control Prasanna_b_r3-Jun-03 19:35 Prasanna_b_r 3-Jun-03 19:35  Hello, I didnt find the option of enable Horizontal Scroll Bar in the resource editor of VC 6.0 for a List Control. I had already tried putting WS_HSCROLL in the resource file manually, but still it doesnt work. I would appriciate the help Thanks in advance Regards prasanna Grid control AlenCk3-Jun-03 1:08 AlenCk 3-Jun-03 1:08  Hi! I need free grid control with grouping function. Thanks for any help. Re: Grid control Anonymous3-Jun-03 3:23 Anonymous 3-Jun-03 3:23  look in the most popular section, Chris's article Re: Grid control Rage3-Jun-03 3:29 Rage 3-Jun-03 3:29  http://www.codeproject.com/miscctrl/gridctrl.asp[^] ~RaGE(); Re: Grid control AlenCk3-Jun-03 20:33 AlenCk 3-Jun-03 20:33  i think that you dont understand what i need, i know about this grid but you can not group by field like most of commercial functions have. I need grid with internal grouping Problem with templates&lt;&gt; and classes Zibar2-Jun-03 23:53 Zibar 2-Jun-03 23:53  Problem with templates<> and classes I have this kind of class (first of all - I use VC++.NET) class XMLParser { struct Scene { LinkedList< SceneObject > objectList; } struct SceneObject { } LinkedList< Scene > sceneList; XMLParser ~XMLParser(); // static void StartElementHandler(void * data, const char * element, const char ** attribute); static void EndElementHandler( void *data, const char *el ); } I'm using the expat library for XML parsing. This class should parse an .xml file and create a list of scenes. XMLParser constructor initializes the expat XML parser and the StartElementHandler and EndElementHandler are callbacks that handle the parsing needed by expat. The problem is the templated LinkeList class. I want to "new LinkedList< Scene >()". I can't do it inside the class decalration and I can't do it outside of the class declaration. In the first case I get a compiler error (obviously) and in the second one a linker error. If I do: XMLMovieParser::sceneList = new LinkedList< Scene >(); I get C2512 no appropriate default constructor available and C2955 use of class template requires template list If I do inside the constructor: sceneList = new LinkedList< Scene >(); I get an unresolved external symbol errors: LNK2001 and LNK2019 etc. the full class is too long to post Re: Problem with templates&lt;&gt; and classes Joaquín M López Muñoz3-Jun-03 0:27 Joaquín M López Muñoz 3-Jun-03 0:27  This surely is not the whole answer to the question, but sceneList = new LinkedList< Scene >(); is trying to assign a LinkedList< Scene > pointer to a LinkedList< Scene > object. Check the definition for LinkedList. If you've got some references around, the compiler won't be able to generate a default constructor, maybe this is the problem. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: Problem with templates&lt;&gt; and classes Zibar3-Jun-03 0:30 Zibar 3-Jun-03 0:30  LinkedList< Scene > sceneList; this should be of course a pointer LinkedList< Scene > *sceneList;
