I am currently developing a chat application and am trying to include:
Various states, like MSN does, available, busy and away.If the user doesn't touch the keyboard for one minute, the state of the user isto be changed into Away.Or something similar to these.I also need the program to be able to play a sound while running.
I working on a project wherein i need to merge 2 or more files. but while the program is running or doing the specified descripted job. it seems to be standing still, which may confuse the user that application is not working or not responding. so i want to add a progress bar or anything related to show that the application is still running. can someone explain or tell me how to add this in my program. can you explain me with a simple program or something.

View 1 RepliesGOCR is a common Optical Character Recognition software that can be implemented into almost any programming language. You must convert the image you wish to convert into a PNM file and then proceed to call the executable OCR file. I cannot find any conversion methods for Visual Basic, nor am I quite sure how to send the file to the program and retrieve the text. Has anyone ever worked with GOCR or happen to know anything above?

View 2 RepliesI've decided to make my own simple scripting language parser. I've created about 50% of it and it works great! I need to implement "functions". What ever program uses my parser needs to be able to connect functions to my parser for customization. I've implemented "Lua", a scripting language, in a vb.net application of mine. To connect functions to the Lua Parser it used reflections.I need to be able to (by only knowing the name of the function and its structure) call a function connected through the implementing application.

View 2 RepliesLet's say an application needs to persist mostly immutable data. Let's say the application's data files can grow fairly large. How would you implement a simple transaction processing so that changes are either successfully committed or rolled back?
The only requirement is to use built-in .Net libraries. (no databases, no third party libraries)
Here's my current solution. The data file will have three main sections: (1) header, (2) data, (3) index. For now, the header section simply contains an offset to the start of the index section. The data section will store mostly immutable data. The index section will contain serialized objects with enough information to access the data section.
When the application starts, it only needs to deserialize objects from index section. Anything from the data section can be fetched as needed. As the application gets ready to write changes, it makes a temporary copy of the original header and index sections. These would be small relative to the data section. New data would then be appended to the original data section. Once all data has been written, in memory objects would be serialized to the end of the file to become the new index section.
If all this goes without a hitch, the temporary file can be deleted. If something goes wrong, the temporary file can be used to restore the data file to its original state.
Will this work or is there a more elegant approach?
I don't want it to be MultiThreaded. i read some tutorials and have a good idea. but unfortuantely all the tutorials on the web write code without explaining. so is anyone here has a good knowledge with Chat application ?

View 2 RepliesI am trying to develop a chat application using Visual Basic 2008. I have referred some articles on the internet like [URL]...rogramming.htm and got the concept of connecting and sending data. But when it comes to real world chat applications, there is user authentication and all that. So I was wondering if it is possible to make my own Windows Live Messenger or Yahoo Messenger!!. I searched web for such a sample or source code, but could not find any. Has anyone here created such an application??

View 1 RepliesI have been trying for years making a network app.I need linked to a video or something, mainly on msdn or some microsoft site, because youtube created videos for coding aren't all that helpful as most of the microsoft made videos.
I need not linked to things like multi-user tcp chat application, as i have looked at these, and even found no code solution, but the no code doesn't allow too much customization and hard to deal with data received to make your own commands send and receive and have events for them.
The multi-user tcp chat application, it doesn't explain anything, just gives you the code for you to look at, and well, it's hard to understand.

View 10 RepliesSomeone gave me a link to a Multi-User TCP Chat application once, but, there is a flaw in it, where it wont do special characters, such as Alt+1 will become a different character to the server than the one that was sent. Even I tried to see if the output was usable but it sees it as multiple chars, when it is only 1, and I can't find a link between what it sends and what the character is, so I can't just tell it based on whats sent what the char is, because I see no relation, I would have to type it out for each and every special character.
