We have a situation wherein we need maximum uptime for database connectivity which is on our LAN. However, we would like to connect to the server also in the event that the LAN is down. We have option of doing this [switch to dial-up from LAN] automatically using code or manually an operator can do so. The problem is to determine if the current connection is whether on a LAN or Dial-up?

View 5 RepliesI want to write a simple program, which should inform me before any files getting open (like as User account control in Windows Vista or Windows 7).

My program must ask me as "Are you allow this file to run?" and allow it if I allow otherwise terminate the file.
View 2 RepliesI do a lot of programming in VS 2010 on my Windows XP Pro PC. Recently I tried testing my software on a Windows 7 Home PC. For some reason, all of the controls on my forms are slightly misplaced. I also get a bunch of unhandled exceptions I don't get on my pc. For example, one exception said it couldn't access a registry key. Another said it couldn't find the part of a path (it didnt specify which path). What's up? Why is it doing this? My Win XP PC tricks me into thinking my apps are bug free. Guess not.

View 1 RepliesI am writing a application where i need to know which games are installed on a system.I have 3 ways by which i think i can detect the games
1: Scan specific parts of registry and look for key names that match with a List of Publishers. The list is manually maintained.
2: Scan the hard disk for and do same as in step 1
3: run the program in background and check for programs in memory that use a large portion of memory(which games always do) and if they use Direct X ( Which all games do except for some) then its a game.
Now i have been thinking about it and first and second method seems to be in need of a updated database ie list of publishers to make out if a particular program is game.

View 1 RepliesI need code to fit for an 'if then' statement based on an operating system. So let's say I am running windows XP, the program detects it, and with a simple if then' statement it opens form2, if i was running vista, it would open form1. So basically i need something like: If (WindowXP current OS) then form2.open, If (windowsvista currrent OS) then form1.openOf course, the above statement won't work because I need code to support the detection of the O.S.Note: I just need code for just these two O.S'es, also I don't care if its Windows XP SP1 2, or 3, just as long as it's an XP.

View 4 RepliesI have a small VB .Net application that, among other things, attempts to substitute system wide typed text by the user(hotstrings concept). To achieve that, I have deployed 'ahk2exe' and 'AutoHotkeySC.bin' with my application and did the following:When a user assignes a new 'hotstring':
Kill 'hotstring' exe script file if running Append new hotstring to the script file (if non exist then create a new one)Convert edited/new script file to exe (using ahk2exe)Run the newly converted script exe(somewhere there I also check if the hotstring has been already assigned)However, I am not totally satisfied with this method for the following two main reasons:
The extra resources deployed with the application. Lag: The time it takes for the system to kill the process and then restart it takes a minimum of 5 seconds on my fast computer and more on other computers. That amount of time is much more than the time it takes the user to assign the hotstring, minimize/close the window and then test his/her new hotstring. When the user does so initially with no success they will think the process failed. So this method is not very good for user experience.I am looking for a different method or implementation. May be using keyboard hooks? Or maybe adding a .dll library that achieves the same. Are there any resources you know about that might help (free or commercial)? What is the best way to achieve my desired goal?
