I have recently started playing with sockets, so now i have set up an instant messaging app. it works like it's supposed to however, theres a slight problem. short of arranging for both parties to come online via email or something there's no way for the other person to know that someones waiting for them. So i'm basically looking for a way to send a pop-up message to tell the other dude to get his ass online,is there a way to display a message on a target pc's screen without a client application running and actively listening for an incoming command?

When the second message box gets closed the user remains on the same window, and the part of the title bar from the message box is still visible just above the windows text box. It seems that window did not get refreshed. How to handle this?
I'm facing a problem with my code. it's all about an if command. When the variable
xglobal doesn't fit the rule (if xglobal >=0 and xglobal<=xlimite) a message box should appear, so it does. However, after being closed the message appears again and so on.

I got this monitor that can turn 90 degrees & another program will rotate the display when it detects it has been rotated, I have a few questions though.
1.How can I detect when the monitor has been rotated (the monitor is hooked up via vga & no other cable goes to PC so I am guessing the message is sent across the vga cable).
2.How can I make it actually rotate the screen when the message is detected that the screen has been rotated?
I would download the other software but it's just some bulky & slow software for a small thing, windows has the ability for rotation built in, just not the auto rotation feature like the program, I just need to detect the message & make windows rotate the screen.

I created a server-client application using the asynchronous socket. I found the problem when closing a socket on the server, applications so closed. The procedure that I do to close the socket server is:
Terminate the listening thread. Close the client socket is still connected to the server. Close the server socket.
How to prevent the application is closed, when I close the server socket?
Protected Friend Sub CloseServerSocket(ByVal IPAddress As IPAddress, ByVal socketPort As Integer)

View 2 RepliesI have recently created an application where a lot of data is loaded into objects when the application starts up, and other data as it is required. For example if the user requests the catalogue page then it will load all the top level category data into objects of type Category. This will then stay there to be used by other users (who will therefore not have to load this data into objects) and can be altered by admin if they happen to login during the same application instance. I know this is not the most efficient solution, as pointed out below, but it works and the page load, at the moment, is not too long. It is very quick if most of the required data is already loaded into objects. It is also tailored to the business' needs - unlike other techniques such as Linq-to-SQL.
View 1 Repliesi am developing one application for which i want it to stick to the edge of the screen when dragged near screen edge.
View 2 RepliesI was trying to figure out the cause for this . What i understand is :
1. .net starts splash screen in different thread.
2. Someway when main form load event is finished or about to finish , then splash screen is disposed.
Now in this case , i think dispose method of the splash screen gets fired from the main form , even when splash screen initialization is not finished yet.
