im not sure about the title , but i will try to explain , if you use a program like resourcehacker and check the bitmap files in C:\Windows\System32\shell32.dll there is 2 bitmap files Bitmap_633 and Bitmap_632 these 2 files are the leftside panel in the control panel features like windows firewall ,as far as i understood the Bitmap_632 is a layer to add effects to Bitmap_633 so my question is what is this technique called and if there is a tut on how to use it in vb.net would be great

There are plenty of tutorials here on CodeProject[^], and a similar search on Google will probably find lots more.
One of these days I'm going to think of a really clever signature.

You are probably referring to alpha blending which makes bitmaps semi-transparent. In older systems each pixel in a bitmap consisted of 3 fields Red, Green and Blue. With alpha-blending a fourth field, Alpha, is added which gives the opacity of the pixel, from 0 meaning opaque to 255 meaning transparent.

I need to read and process a textfile with fixed filesize from an unc network path. The content of the file gets updated in different time intervals (from 0.5 - 10 secs). Anybody is having any idea to accomplish this task?

Plenty of ideas. What have you tried and where are you stuck?

I thought of using FileSystemWatcher to respond to file system changes but file system monitoring of remote shares is always going to be somewhat unreliable. Maybe a polling mechanism could do the job (don't know how to adapt to the different time intervals)?

True.

..check the remote file, every .5 second? What does realtime mean here? I'm guessing that it needs be refreshed within 10 seconds, given the remote folder.
Do you "need" the share? Or could you run an app on that remote computer that reads it locally (!) and then updates all connected clients?

So what? You have some other requirement other than using the Internet Protocol for Internet chatting?

It predates the Internet and is still used today, so they've got to be doing something right with it!
|
|
|
|

not necessary across the internet , its between users , that users use my application in local lan Example an accounting program in a company any user can send message to other user use the application
i hop the issue is clear now
thanks

Well, you did say in your original post "I hope I was clear". Nope.
If you mention chat, everyone immediately thinks two remote machines over an IP network.
|
|
|
|
|
yes its not between 2 machines its between users
thanks to you Dave
|
|
|
|
|
That makes no sense. If it's not between machines and is instead between two users, couldn't they just turn their heads and talk to each other??
Of course it's between two machines!
|
|
|
|
|
Of course it's between two machines
when i mean two user that means two users use same accounting application, and that users one in department of company and other from another department
"again same application on two machines and single DB 'SQL Server"
thanks anyway Dave

In a world where email is ubiquitous and, almost so, a corporate instant messaging system, is there really a need for this??
I think your application is trying to solve to entirely seperate and unrelated problems that do not need to be in a single application.

This sounds like a homework assignment.
Try something like this ...
Create a message table with timestamp, usernameTo, UserNameFrom, Status (Read/Unread), MessageText.
When someone sends a message, you insert a record into this table.
You would have to create a client application which checks to see if a message is pending for your current user and retrieve it from the db and display it in a chat window.
The other guys who replied are correct, you need to investigate TCP/IP chatting otherwise your client application will be constantly polling the db for new messages. However, i think this basic design will get you through your homework assignment.
