My (local, windows/mono) app logs important events to a text file. In case of a sudden crash/failure/forced exit, no data should remain unwritten (as far as it's possible). Thus I currently use a simple append-to-text-file approach:

I am working on a Visual Basic application that is returning Event Logs using WMI. I only want the latest 5 application, error events, but as I have the code now I get everything and then need to loop through and grab the first 5.
Dim wqlEventLogAs ObjectQuery =New ObjectQuery("SELECT * FROM Win32_NTLogEvent WHERE Logfile = 'Application' AND Type='Error'")
Dim objEventLogAs ManagementObjectSearcher =New ManagementObjectSearcher(myManagementScope, wqlEventLog)
ForEach objMgmtAs ManagementObjectIn objEventLog.Get
Next
I have tried a number of ways to add "Top(5)" to the query but each time I get "Invalid Query".

We are currently hiring at the company where I work, and here the codebase is in VB.Net.We are worried that we miss out on a lot of brilliant programmers, who would never ever consider working with VB.Net.
My own background is Java and C#, and I was somewhat sceptical as to whether it would work out with VB, as - to be honest - I didn't care much for VB.
After a month or so, I was completely fluent in VB, and a few months later I discovered to my surprise, that I actually like VB. I still code my free time projects in C# and Boo though.
So my question is firstly, how important is language for you, when you choose a new programming job?
Lets say if its a great company, salary is good, and generally an attractive work-place. Would you say no to the perfect job, if the language wasn't your preferred dialect?VB or C# is one thing, but how about Java or C# etc.Secondly if the best developers won't join your company because of your language or platform, would you consider changing, to get the right people?
I saw one post on which someone was recommended to sign he's assembly, why is this important?

View 1 RepliesDim strArray() As String = {"test1", "test2", "test3"}
strArray.SetValue("", 1)
Console.WriteLine(strArray.Length)

This still leaves me with an empty array value, how can I just delete it or can't I? Do I have to use an arraylist and if so how do I convert an array into an arraylist?
Why is it so important to turn option strict on? I admit I am not a professional programmer, but I have written a great number of useful applications...I am fairly well (although self) educated in object oriented programming... I even write programs for my business...I always have felt that I am missing some background theory that is probably really important (I have a grad degree in math, no comp sci)...I have never turned on Option Strict for any project I have ever written, and I guess I just want to know, theoretically why is it important?
View 10 RepliesI want to code in our VB.net to be a little easier to follow both to improve readability and also make it a lot easier to know the best place to put a new bit of code/feature.
Essentially, I'd like to have a 10,000 foot "outline" of the code" with hyperlinks from the outline to the code.
It needs to be portable, so BookMarks won't do the trick (I think). I'm thinking maybe TODO comments. I'd like to create our own Todo style comment like "Outline" or something but that keyword would need to be in the config file for VS as well (but then it's just one thing to keep sync'd).[code]...

View 3 RepliesI know you can validate textbox text by using the keypress events. But the form i'm working on has multiple groupboxes with multiple textboxes. So rather than having a sub routine to validate every groupbox, i was wanting to have just the one keypress event that handles the textbox entries, and depending on the textbox calls a specific validation routine.[code]

View 5 RepliesI put Label1.Text = Watch.Elapsed.Milliseconds And notice that it goes from 0 to 1000 milliseconds and then back to 0 starting over every time.Then I do some tests and put,[code]...
Whenever I press e, it logs the value in count and displays it.[code]....
This should end program once it hits 5 milliseconds.But the problem is it doesn't.On one of my test runs i notice it does end, but only after a little while. Does this mean VB has a hard time detecting the stopwatch or something?
