Text->Gif [James Pullicino]14-Jun-02 1:42 [James Pullicino] 14-Jun-02 1:42  Hi all, I would like to make a program which converts normal text to a gif. What technologies should I be looking at? GDI? GDI+? I am looking for something lightweight and fast. Thanks, James Drinking In The Sun Forgot Password? Re: Text->Gif Navin14-Jun-02 3:01 Navin 14-Jun-02 3:01  You'll need to find a library that can create a .GIF file. You can either try and find the spec and code it yourself, or find a third-party library that does that kind of conversion. Beware though, that unless you have a license from Unisys (I think that's who owns the patent on the compression used in .GIF format), your code will technically be illegal! No generalization is 100% true. Not even this one.

The answer is simple. In all cases, a written license agreement or statement signed by an authorized Unisys representative is required from Unisys for all use, sale or distribution of any software (including so-called "freeware") and/or hardware providing LZW conversion capability (for example, downloaded software used for creating/displaying GIF images). " this is from the Unisys website. (they've moved the pages and now i can't find the page i got this from, though it was there like two weeks ago). note that this is a change in their position from earlier times (pre-1995), when they did allow non-commercial use. see burnallgifs and "A Software Developer's Perspective" for some interesting reading. -c Cheap Oil.

Re: Text->Gif Chris Losinger15-Jun-02 7:49 Chris Losinger 15-Jun-02 7:49  i don't know. i haven't seen anything that talks about it. but, if you're using the program to do something that ends up in public (like, using the code on a webserver to generate a web page hit counter, for example), then it's not really "personal" use. save yourself the hassle, just use the PNG format. it compresses as well or better than GIF, is more flexible, has no patent concerns; the basic flavors are supported on all browsers. -c Cheap oil.

(empty rows rest) mloibl14-Jun-02 1:24 mloibl 14-Jun-02 1:24  Hi, I have a listbox (CListCtrl, report style), and I feed it with data. If its contents gets too large, a scrollbar appears on the right side. Under some circumstances, when removing some items again, empty rows rest in the control. I do not know if it has to do something with the scrollbar (e.g. only if it disappears or so). Any suggestions ? A bug ? Any equal experiences ? Heard about it already? On the internet I found some equal situation: Anybody aware of bug in CListCtrl CListCtrl funny stuff (bug or incorrect use?) Socket behind FireWall unknown soldier14-Jun-02 0:54 unknown soldier 14-Jun-02 0:54  I like to connect to a certain port of server on Internet. For this purpose my application uses the well known function of WinSock API, connect() having prototype : int connect( SOCKET s, const struct sockaddr FAR *name, int namelen ); But, before i use this function, i have to populate "struct sockaddr" about the port and address of server. right !! Suppose, my client application is running on a machine behind a firewall eg SOCKS. Then please tell me how can i connect to server under this condition. I shall be thankful if you explain me clearly or write some example pseudocode. There is an example present at CP, but it is not too good to understand and it uses MFC Socket Classes.

What i want to ask is that if firewall present at client side then how can we connect to server. Re: Socket behind FireWall markkuk14-Jun-02 4:59 markkuk 14-Jun-02 4:59  Use SocksCap.

If you use extern "C" that's to avoid name mangling.
