  Is there away to check a valid DOS path in c# ex: if the user types zzz:\test.txt and the path is invalid, return error message.   using VS2003 .NET1.1   Thank you, Thank you, I will check it out. I found something, would like to share. another way can be checked if the path is valid or not, using try and catch: try { } catch (COMException cex){ Response.Write(cex.ErrorCode); if ( cex.ErrorCode == -2147166139 ) { //invalid path format. } } using File.Exists to check path validiy is a wrong idea and should never be used.

• Lei Jiang GQoS vs QoS2 vs qWAVE

  I have some applications that make use of GQoS under XP and Server 2003 and I've heard a lot about QoS changing in Vista. I've been looking all over the MSDN web site, but I'm still a little confused. What's the difference, if any, between QOS2 and qWAVE The qWAVE documentation states that it's "mainly targeted for use by multimedia applications that require network streams on a home network". Does this mean I should still use GQoS for my enterprise applications under Vista and Longhorn Thanks Kevin O'Connor Interactive Intelligence, Inc. QOS2 is the api name (header file is qos2.h) for the qWAVE networking technology. You are correct that qWave is mostly targeted at multimedia application ...Show All

  Hello Everyone, I am trying to write code in my c# windows program to send email.  I found good tutorials online to get this done.  Most of which use the System.Web.Mail namespace.  When I come to write that in: using System.Web.Mail; I get this error: The type or namespace name 'Mail' does not exist in the class or namespace 'System.Web' (are you missing an assembly reference ) I even tried: using System.Web.Util;............but I pretty much got the same error message.

• mliesmons Maintaining an Activity Log over multiple classes

  Hi all, i have a class called ActivityLog.cs and this basically creates a log of whats going on in my console app. i construct it like: ActivityLog Activity = new ActivityLog(); then you use it like activity.log("this is one entry"); and when the program is done you can mail out the log like activity.Email("me@me.com","me@you.com","the log file"); My program uses three different classes, right now the activity log only works with the first, well it will work with all three but only if i construct a new log file for each class, i was hoping someone could help me figure out a way to pass the log back and forth during the execution of the different classes.

  How can I retreive the local computer's accounts passwords Is there a way to search through all of the keyboard characters to determine the password characters one by one Thanks, (PS: I'm not trying to break into an account) At one time SysInternals had a brute force password cracker for WinNT.

• zwp while (true)... need help!!

  I thought I knew quite a lot about programming but when I came accross a bit of code like: while (true) { ...do something... } I had no idea how this works... I know that it's a conditional loop and while it is true it loops through performing whatever tasks there are to do... BUT what is the (true) part how does that work if it loops while(true) what would make it false since it's not a local variable or anything and you cant say IsRunning = false; it just always is true... Does it mean that while app is still running or something... That's the only solution I can come up with is that it means while( app is running){...}... Am I right Can someone please take the time to explain this to me and maybe give me the proper name for referring ...Show All

• PLMK Terminating a process using WMI

  Hi, I have been told that this is possible but I can't seem to find any sample code anywhere. Anyone know how to do this Thanks. except your posting how to do it locally and sven is proposing a remote/local function. It is: Process.GetProcesses("remoteMachine") will give you a process collection of remoteMachine. Process.GetProcessByName("notepad", "remoteMachine") will give you a collection of processes named notepad on remoteMachine. Given that you have access rights on remoteMachine... -- SvenC you are aware that you can use the Process class to terminate a process right It would be cheaper also than using WMI, if its ...Show All

• kangalert best way to read pipe delimited text file?

  I am trying to read in a pipe delimited file and do certain processing for each field. I was just wondering what the best way to strip out each field is - is there anything built in .Net that will easily allow me to do this Or do I just loop through and remove each field myself Also, would it be best to strip each field out into a dataset first, and then do the processing Or, do the processing while I am separating each field Or does it not matter Thanks!
