probably because they have licenses for all of their apps, and their apps use the same stuff we do (same COM objects, GDI+ functions, etc). it was probably just a matter of not wanting to have every image loading call ask "OK. who's calling me this time?".
or, maybe (and this is what i prefer, for no good reason), MS is trying to make GIF support so easy to come by, that every app made will use it. that way Unisys has no chance of stopping everyone. and, it sticks a thorn in the side of independent toolkit developers 
meanwhile, people continually ask me "i can read GIF in VB/.Net/any of the dozen toolkits here; why can't i do it from your library?"
my answer, "because i don't want to go to civil court to fight an huge corporation" doesn't get me the sale.

So it's an annual fee ?

no. it's an advance on 1/4ly royalties. and at the rate the economy's going (hence sales), i think i'll still have some money left over, by the time their patent runs out (next year).

because there are only two formats: JPG and GIF. everything else is for losers.

hi, dose anybody know how i can wright a simple visual c++ program to encrypt/decrypt entered data by a user using the caesar cipher. And displaying the encrypted data in a file or box.
I have not used visual c++ much and having great difficulty getting grips with the code.
Any help would be appreciatedm. thanks

If you having problems coming to grips with the code I would suggest searching for a third party lib. Anything other than simple ascii encryption maybe XOR is pretty difficult. I wouldn't attempt this myself until I fully understood the algorithm and language at hand.
I would look for a 3rd party lib...yup for sure...i'd be much easier.
p.s-You might take a peak at the windows CryptoAPI, I dunno about ceaser cipher's but I think it supports triple DES.
Cheers!

What is the ceasar cipher? Is that the algorithm where the letter A gets mapped to a number between 1-26, then B to a different number and so on through Z until all of the letters and numbers are matched?
Is the problem that you are having have to do with the actual encryption, where to get started on your program, or the file part.
Does your program need to be displayed in a GUI, or can you use the console. If you can use the console, this would make your program alot simpler. Simply start with the fstream objects to read your encrypted file in to memory.
Walk through all of your encrypted data, byte by byte, and convert from the encrypted code to the real character, placing the decrypted character in a new buffer.
Then display the new buffer with cout.
I know this is general, hopefully I have helped, if you have a specific question feel free to give more details.

Hey Guys
I probably put this post up before but oh well, I have a dll that integrates with explorer and when i try and put my own exported funtion in it crashes the program when i try and access it any ideas.

Hi guys,
In VS 6 C++ there was no Bool CArchive Operator so we made one of our own where it used an int for true = 1 false = 0, naturally.
Now I see .NET C++ they have been clever and added one of their own, how can I disable that and use my own without having to derive a class from CArchive and overloading it??
I would be interested to hear if anyone else has this problem

I guess you defined your homemade operator as a global CArchive& operator<<(CArchive& ar,bool b), right? If so, and if you can afford some syntax ugliness, you can force selection of this operator instead of the built-in one by calling it explicitly like this:
CArchive ar;
...
operator<<(ar,true);
operator<<(ar<<1<<2,false)<<3<<4;

How can avoid this?
Thanks in advance.

In some cases, these exceptions are caused by calls to the Win32 API from your program with incorrect parameters --check for that inspecting the particular API where the exception is showing. Could you post the offenging code? Other than that, caught first-time exceptions is the handler's businesses. I wouldn't worry too much if everything's working.

Hi !
How can i get the handle to another running App ? (For example, Notepad).
Thank you !

If you already hava a window handle for that app (obtained for instance with FindWindow), <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/windows_5y90.asp">GetWindowThreadProcessId</a> gives you the associated process handle.

PS: Oops, did I say process handle? GetWindowThreadProcessId gives you the process id. From this you can retrieve the process handle with <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/prothred_478z.asp">OpenProcess</a>. Regards.

I want to oprn an avi movie in the media player in a vc++ program..
Thanx in advance

Experiment with ShellExecute. You don't need to specify the executable name for the Windows Media Player, just the name of the .AVI file (ShellExecute will know how to locate the player for the file.)

Simple:
Use "Media Player ActiveX",its one standard activex in visual studio.

is it possible to change the project after the application has been created. i.e., I'm using a demo software of the net, project was called OpenGL, but I wanna change the name. If I can't do that, I atleast wanna be able to change the title when i bring up the MDI window. I don't want it to say openGL. How can I do this?
|
|
|
|
|
Yes is posible. Edit the file .dsw and .dsp with notepad and change the names and reference to old name...
Y think that CP has any aplication that make that, but is more quickly edit the files and change the names that look for the application...;)

If you want to change the application name that appears in the captions of the various windows created by the app you can do that by modifying the relevant strings in the string table resource (e.g. IDR_MAINFRAME, IDR_<yourappname>TYPE, AFX_IDS_APP_TITLE etc).
