Re: Read/write from a binary file @ specified offsets 31-Jul-01 9:58 31-Jul-01 9:58  Thanks for your help! Sorry to ask again but how do I read INTEGER or LONG length values in from a binary file? At the moment I can only get single bytes. Do I use GET or READ? How to I modify the following code to read an integer length value from address 4110 in the DAT file? ============================================== ofstream path("c:\\windows\\desktop\\debug.dat"); ........................ int pos = 4110; path.seekg(pos); int bytevalue = path.get(); ================================================ Sorry to be dumb, tried to work it out myself but failed (& no online helpfile) cheers Richard Edwards CListView Not cooperating... Joseph Dempsey27-Jul-01 6:12 Joseph Dempsey 27-Jul-01 6:12  Does anyone know how to force CListView to select an entire row when you click on an item... by this I mean i insert a certain number of items each with 3 subitems... i want the item AND its subitems to appear highlighted... Any help would be appreciated.

Matt Gullett27-Jul-01 6:20 Matt Gullett 27-Jul-01 6:20  Call the SetExtendedStyle function with LVS_EX_FULLROWSELECT as the parameter. Re: CListView Not cooperating... Diarrhio28-Jul-01 3:21 Diarrhio 28-Jul-01 3:21  I don't believe that will do the trick. I think the LVS_EX_FULLROWSELECT parameter only allows you to select a row by clicking anywhere on any column in that row, rather than on just the first column text. It won't actually highlight the row. To achieve the highlighting, you'll have to custom draw the control yourself, and you can find many examples of that on this site and on codeguru in the listcontrol sections. best of luck Cross Class Functions Matt Newman27-Jul-01 5:50 Matt Newman 27-Jul-01 5:50  I need to access function1 in class2 from class1. Everytime I try to do this i get an error about statically linking. "illegal call of non-static function........ it is Error C2352. Since this function takes values and updates controls based on these values I can't use static functions. Can anyone tell me what to do ? -Matt Newman Re: Cross Class Functions Chris Losinger27-Jul-01 5:53 Chris Losinger 27-Jul-01 5:53  you can only call non-static (ie. normal) methods on an object if you have an instance of the object. so, either create an instance of class2 or find an already-exisiting instance of it. -c ------------------------------ Smaller Animals Software, Inc. http://www.smalleranimals.com Re: Cross Class Functions Matt Newman27-Jul-01 6:04 Matt Newman 27-Jul-01 6:04  you can only call non-static (ie. normal) methods on an object if you have an instance of the object. so, either create an instance of class2 or find an already-exisiting instance of it. I am a beginner and I am not sure what you mean by create an instance. Could you elucidate this for me? -Matt Newman Re: Cross Class Functions Chris Losinger27-Jul-01 7:05 Chris Losinger 27-Jul-01 7:05  This is really one of the basic principles (maybe the most basic principle) in all of Object Oriented programming: you have a set of functions and properties grouped together that comprise an "object". You can tell the object to do something (invoke methods on the object), to report its state, to change its state, etc.. CString myString; After this statement executes, "myString" is an "instance" of CString. Or, you could say "myString is an object of type CString". Now you can call CString methods on myString: BOOL b = myString.IsEmpty(); myString.MakeUpper(); etc.. What you can't do is call (non static) CString methods without having a CString object to call them on: CString::Reverse(); This statement makes no sense (at all).What are you trying to Reverse? There is no object there. It's a verb without a noun. -c ------------------------------ Smaller Animals Software, Inc. http://www.smalleranimals.com Re: Cross Class Functions Matt Newman27-Jul-01 8:23 Matt Newman 27-Jul-01 8:23  Now I remember.

Tomasz Sowinski27-Jul-01 4:50 Tomasz Sowinski 27-Jul-01 4:50  I think that you should activate a frame, not a view - this is MDI app, right? Do you have multiple views in one MDI child frame?

How do i do this, a sample piece of IDL is shown for one of the interfaces that already exists on the object. Is there anything i need to watch out for? where do i get the uuid from [ uuid(5E816CCA-628A-4959-B1FE-05465C3393EB), helpstring("IDocumentVision Interface"), pointer_default(unique) ] interface IDocumentVision : IUnknown { } Cheers Rich Re: Adding A Interface Not Active27-Jul-01 8:18 Not Active 27-Jul-01 8:18  You can get the uuid from GUIDGen.exe, should be in the tools folder in your Visual Studio installation.

I decided to turn the background gray, so I called SetBkColor() in OnInitialUpdate. The problem is, that this backgroundcolor can only be seen in areas, where no items are draw and as a flickering background when scrolling the list. What must be done to override the standard item background color? Pseudocode is code to demonstrate a concept, not designed to be run. Like certain Microsoft software.

On handling this message, i can decide to paint or not paint the background. This is well doing, and my desired black background is already painting but not at the items background. That is my problem. The areas, where no item is 'overpainting' are black. Any idea? -------------------------------------------------- "Pseudocode is code to demonstrate a concept, not designed to be run. Like certain Microsoft software. " Re: Background color of CListCtrl Tomasz Sowinski29-Jul-01 23:12 Tomasz Sowinski 29-Jul-01 23:12  Use identical color with LVM_SETBKCOLOR and LVM_SETTEXTBKCOLOR (or CListCtrl::SetBkColor/SetTextBkColor if you're using MFC): CListCtrl &lst = ...; lst.SetBkColor(RGB(255, 0, 0)); lst.SetTextBkColor(RGB(255, 0, 0)); This should make all background red.
