• Windows Forms Interacting with other windows/apps?

  I know this is possible, just wondering if it's possible in C#.NET, and how it's done. I'd like my application to interact with other apps/windows. Examples: 1) Type some text into a notepad window. 2) Force Firefox to do Help->About. 3) Read text from a notepad window. I realize #3 could potentially be a security risk and .NET may not allow it (imagine an app reading text from some open window and sending it off somewhere via the net). And in case anyone is concerned, no, I'm not trying to write any kind of malware or virus. I'm interested in writing a program that will automate tedious processes in another application. I guess this is similar to Rexx. So, how can I do something like this Yes actually ...Show All

• Visual Studio Express Editions timers

  How can I add a timer to my program Like in admin center you can change the amount of time you spend on the program, then when times up in closes the program Then it wont let you on till the next day Thanks well the theory is this once the timer has been "ticked", save to a file some value, such as a boolean value or something to indicate "false" for not opening today. Or even storing today's DATE in the file. Next time you load the app, open this file, read the value stored, lets say the value stored was date, then compare today's date (DateTime.Now) with the date stored in the file. If both match, don't open it, otherwise, open it. this is just one simple solution but easily hackable - the ...Show All

• SQL Server Using OPENROWSET with an IP address

  Hi I've got an openrowset query that works perfectly if I enter the computer name, but it fails when I enter the IP address. Is there a setting somewhere that I need to enable to make this happen Thanks in advance Everything seems to be in order according to your post. My problem does not seem to be connecting, as the connection works when I create an OleDb connection (c#) to the ip address. Also; the openrowset works when I use the remote machine's pc name. It just doesn't work when I use the IP address of the remote machine - login times out because of no connection. I've even tested it on the same machine (connecting to itsself): Working: select * from openrowset ( 'sqloledb' , 'pcname' ; 'sa' ; 'password ...Show All
