ATC7-Jun-02 6:24 ATC 7-Jun-02 6:24  Hi, Let say we have a List Box dialog (Visual C++ 6.0 MFC), with text on it (Tabs, spacing, linefeed ...) Is there any way in programming (simple) that we can print out as it is (text & screen proportional) & easy to see? a) If I use: m_listbox.GetClientRect(Rect); m_listbox.Print(&printer, PRF_CLIENT); *) I got what I see, but the text size is very tiny b)If I use: m_listbox.GetItemText(i, j, str, 10); k= strlen(str); dc.TextOut(350*j, l+(75*i), str, k); *) The text size is OK, but the printer printout Tabs as "square" symbols ang resulting the print out looks badly (not in-lines) ---> Any one can help? I thought that Visual C++ MFC is a very powerful application, this is supposed to be a simple task (print out as it is)! *) If anyone wants that I send the whole (but very simple) program to see & modify to make it works better ... I am please to send my zip file to anyone!!! It is a desperate request, thanks in-advance! ATC Regarding Timers arthivjii7-Jun-02 6:20 arthivjii 7-Jun-02 6:20  Hi, I am trying to have a Timer in a non-window class(Generic Class). I need to call some non-static function in the class, from the Timer Procedure. As the Time Procedure is non-static I want to know what is the best to way to handle it? Is there an alternate way to create timers other than using "SetTimer" call? Thanks Arthi (Just a Begineer in VC++) Re: Regarding Timers Nish Nishant7-Jun-02 6:22 Nish Nishant 7-Jun-02 6:22  For normal timers, you need an HWND. I suggest that you create an invisible window to handle timer messages.

Does this mean that I cannot create timers for non-window classes and have them call functions in the class? Thanks.

For normal timers you need a window. But you can take a look at Multimedia timers if you really don't want a window, even a hidden one. Multimedia timers are higher precision timers, but their usage is not as simple as that of normal WM_TIMER based timers Nish Author of the romantic comedy Summer Love and Some more Cricket [New Win] Buy it, read it and admire me static text SnapRick7-Jun-02 5:45 SnapRick 7-Jun-02 5:45  Is there a way to add a vertical scroll to a static Text box?

Just a thought. Roger Allen Sonork 100.10016 If I had a quote, it would be a very good one.

Just a thought. Riga, I thought of that. But the static control seems to be a sort of disabled control in that it won't let ya select text and stuff I thought that also meant that even if we add scroll bars they'd also be disabled.

It was Button1.visible = TRUE, or FALSE. I see that there is the same property in VC++ but how I can change it at runtime. And how I can also change the enabled property, so that at some point in the program something is disabled, and after is enabled. For example the Sign OUT button should be disabled, in I am not already logged in. Thanks alot! "Nelle cose del mondo non e' il sapere ma il volere che puo'." Re: Visible Property Tomasz Sowinski7-Jun-02 5:24 Tomasz Sowinski 7-Jun-02 5:24  In VC++ you don't have 'properties'. Instead you have to call ShowWindow or EnableWindow.

If you are talking about Windows 95/98/Me, then no, I do not believe it is possible. This is because of security - it would mean that *any* user could run arbitrary programs on client machines! If you are using Win NT/2000/XP, there are some indirect ways of doing it... like starting up services, etc., if you can log in to the machine as a user with the appropriate priveledges. If you can log on as administrator, you may be able to write your own service, copy it over, and start it up. But that's pretty complicated. You might try checking for Windows vulnerabilities - there may be some buffer overflows or something you could take advantage of. No generalization is 100% true. Not even this one.

You could of course create something simple yourself by letting the server on machine2 ping (send "alive" packets) to the server on machine1. If the server on machine1 don't get these packets within a given time it would assume machine2 is dead and start serving the requests. This would of course require the client application to either have a list of backup-servers to try, or initiate communications using multicast or broadcast. copying windows 7-Jun-02 4:58 7-Jun-02 4:58  hi, how can i code such that all the messages recieved by a certain window is also recieved by any other window i wish.the other windows as well as the subject window are all created byhand? also,where to put the stuff-to-be-put in OnCeate and other such functions in a hand coded control? bye Re: copying windows Mike Nordell7-Jun-02 23:52 Mike Nordell 7-Jun-02 23:52  What you say you want will not work, and I'm pretty sure you aren't really sure neither what you have requested nor what you want. If you for some strange reason want to hang the app, you have to forward all Window messages to another window yourself. PostMessage and SendMessage. But, it will not work. If you're lucky you will just hang your app. If unlucky you will hit one of the bugs in the USER32 subsystem and hang the whole machine. where to put the stuff-to-be-put in OnCeate and other such functions in a hand coded control? OnCreate is just a handler for WM_CREATE. There are many examples of plain Win32 API programming in the SDK. creating new fonts-kinda rougish 7-Jun-02 4:51 7-Jun-02 4:51  hi, i am making a program ,to help my archealogist uncle in some research, to display some text in some ancient writings found in some inscriptions.i want to create new fonts for this purpose. u c,this language has accent marks and also more importantly,the vowels and consonants unite to give a different symbol altogether-like the south east asian languages. now how can i do that?i know Latin characters are easy to code-just use some font editor-but this type? please help me. Re: creating new fonts-kinda rougish Mike Nordell8-Jun-02 0:02 Mike Nordell 8-Jun-02 0:02  If you just want this to be of limited scope, editing and displaying these character in your app, I think you're better off doing your own drawing and composing, and saving the data in your own specialized file format. If you really want to create a font for this language, and generic ways to input this language using the keyboard, I think you'd have to both create a unicode font using a font editor - using only "free" unicode regions, possibly forcing you to use UCS-4/UTF-32 of which (AFAIK) Win32 has no support - and create some kind of IME (Input Method Editor). The latter seems to me like an awful lot of work compared to do your own composing and drawing in a special app. Especially if you don't plan to release a Windows version localized to this language. ListBox case-sensitivity 7-Jun-02 4:02 7-Jun-02 4:02  i have a listbox, and i added case-sensitive strings to it, like: aA AA ... and when i click to AA, the selection moves to aA i tried CListBoxCS, but as i understood the auther added only case-sensitive search to it... or maybe i dont understand something?... please help me to solve this problem... maybe i should use some other lists?
