How to draw flashing lines? hierro13-Nov-01 21:14 hierro 13-Nov-01 21:14  How do I make the lines I draw on the screen flash? Do I have to use palette animation? What's the easiest way? I only need simple blinking or color change. Re: How to draw flashing lines?

First Approach I can use FTP to tranfer the file,I want to shift file at different directroies....eg c:\Yan1, c:\Bridge1 etc. The drawback of this approach is that the file transfer is double. 1-First send file to a virtual directory as FTP needs a virtual directory. 2-Now picks file from these virtual directories and store at desired locations. OverHead Of this Approach Must be FTP Server Must be IIS 2nd Approach Just share a single directory SHARED, and use this directory on client side, Store the file in this directory, and then at server picks file from this directory "SHARED" and do the rest of work Why Better Than First No Need Of IIS No Need Of FTP Third Approach DCOM. By using this approach i can shift files from one computer to other and then manipulate according to desire. No Need Of Extra Packages, So Mr, would u tell me which is the best, If u have any other idea, Plz tell me. Thanks. How to use GetToolBarCtrl().EnableButton? louis13-Nov-01 20:53 louis 13-Nov-01 20:53  I am trying to enable or disable a toolbar button during runtime without clicking on the toolbar itself. When a condition in some other file changes I would like to toggle the toolbar button accordingly. The OnUpdateHandler that the Wizard uses does seem to update. I am using the CToolbar::GetToolbarCtrl() and CToolbarCtrl::EnableButton(nID, FALSE) because I'm working in different files, calling a function in CMainFrame. However, the return value from EnableButton is FALSE. Why is this?? Can anyone please tell me what I am doing wrong??? m_MyToolbar is the CToolbar object which successfully has loaded my toolbar in my application. Now I just want to enable/disable a button on this toolbar... file_A.cpp void function file_A () { cMainFrame MainFrame; .... .... int nSuccess = MainFrame.m_MyToolbar.GetToolbarCtrl().EnableButton(ID_BUT1,FALSE); ... ... } Any help appreciated..! Thank you. Re: How to use GetToolBarCtrl().EnableButton? Nish Nishant13-Nov-01 21:39 Nish Nishant 13-Nov-01 21:39  have you done this?

It works fine now. Kind regards. Re: How to use GetToolBarCtrl().EnableButton? Michael Dunn13-Nov-01 22:03 Michael Dunn 13-Nov-01 22:03  You're making a new CMainFrame object? That's the problem. You need to access the existing CMainFrame which is your main window: ((CMainFrame*) AfxGetMainWnd())->m_MyToolbar.GetToolbarCtrl().EnableButton(ID_BUT1,FALSE); --Mike-- http://home.inreach.com/mdunn/ #include "witty_sig.h" your with and Re: How to use GetToolBarCtrl().EnableButton? louis13-Nov-01 22:42 louis 13-Nov-01 22:42  Thank's a lot. It works fine. Kind regards. Input box David Fleming13-Nov-01 20:04 David Fleming 13-Nov-01 20:04  Isn't there a "standard" dialog for simple input from the user (something akin to InputBox in VB)? All I need is a simple prompt, a single edit box, and OK and Cancel buttons. Being able to supply a default value would be bonus but not necessary. I would swear I've seen it, but I've drawn an absolute blank. Thanks. Re: Input box Nish Nishant13-Nov-01 20:21 Nish Nishant 13-Nov-01 20:21  There is no InputBox equivalent in VC++ You will have to create your own dialog box Nish Sonork ID 100.9786 voidmain www.busterboy.org Nish is a BIG fan of Goran Ivanisevic Re: Input box David Fleming13-Nov-01 20:25 David Fleming 13-Nov-01 20:25  Hmm. I'm surprised. Thanks for the response. I don't mind creating my own, I just figured there would be a standard dialog (common dialog) for it. BTW, I'm a fan of Goran myself. I was quite excited when he won his slam this year. Re: Input box Nish Nishant13-Nov-01 21:29 Nish Nishant 13-Nov-01 21:29  David Fleming wrote: BTW, I'm a fan of Goran myself.

Templates and Unresolved Externals Xavier Shay13-Nov-01 19:51 Xavier Shay 13-Nov-01 19:51  I'm trying to implement a class not unlike CList, XList. I'm using a template template <class T> class XList and when I compile I get unresolved externals errors for my constructor and deconstructor. I originally got this error for all my functions but I fixed it by adding 'virtual' to the front of the declaration. This doesn't seem to work with the aforemention functions. I'm declaring them thus: XList(); virtual ~XList(); template <class T> XList<T>::XList() { // Constructor Code } template <class Tglt; XList<T>::~XList() { // Deconstructor code } Any help would be appreciated - X Re: Templates and Unresolved Externals Oliver Anhuth13-Nov-01 21:31 Oliver Anhuth 13-Nov-01 21:31  Did you put the function definitions into the same file where your template class is declared (e.g. into the header file and not the .cpp file)? The compiler requires the functions definitions to be in the same translation unit than the class declaration. Oliver Re: Templates and Unresolved Externals Xavier Shay13-Nov-01 22:43 Xavier Shay 13-Nov-01 22:43  Thanks, it worked - X Re: Templates and Unresolved Externals Krouer14-Nov-01 23:23 Krouer 14-Nov-01 23:23  Did you mean that it's not possible to declare the class in a h file and the implementation in a cpp file? I have the same trouble as I convert my list which use void* to use template. But I don't move the code from cpp to h and when I link the library, it's ok. But when I link the application , I get link error. Does it exist another way to move the implementation from cpp to h for solving this kind of problem? Bruno Re: Templates and Unresolved Externals Oliver Anhuth15-Nov-01 22:58 Oliver Anhuth 15-Nov-01 22:58  When you use your template class in more than one source file you should put the class declaration and the function definition in the same header file. Most template libraries like STL, ATL, WTL ship without cpp files.

Could someone please send me a simple example? I am a real beginner using Win32... PLEASE HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!! Re: Win32 Socket Nish Nishant13-Nov-01 18:34 Nish Nishant 13-Nov-01 18:34  take a look at jon sagara's triple-post below. rcopy.cpp and server.cpp should get you started.
