Error - (10061) ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't Connect To MySQL Server On
Jun 4, 2010I'm connecting to my mysql server using ODBC in vb.net, the database is shared throughout the company because it is used in an accounting program (simply accounting), each user has their own account user/pass to login to the database. I have developped a program that uses the accounting database and combines it with other information, my problem is that at least once a day I get this error when I run my program: "(10061) ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on"and the error persists for at least 4 hours, for some reason it starts to work again later on in the day.

VS 2008 Random Number Generated Is The Same Almost Everytime?
Jul 26, 2010I've got a global random type variable, let's call it rRandom.In my code, I generate a random number like below:
Dim iRandom As Integer = rRandom.Next(0, x)
9 out of 10 times iRandom is 0, the other time it was 1. The code isn't on a timer, it happens when I do something (say clicking a button), so the frequency of the code being called is about 2-3 seconds, I say this because I've had similar issues when generating random numbers really fast in a timer, or with a for loop IIRC.X is a variable that, presently, starts at 3, and will decrease until 0, in which it'll return back to 3. Obviously, if X is 0, iRandom will be 0, but it shouldn't be 0 all the time.I'm declaring the variable globally because I remember, again, having similar issues using local variables, idk whether I should be or not.

View 3 RepliesClearing A Multiline Label After It Reaches A Certain Line Number
Dec 27, 2009My program plays sort of like a novel, where I add paragraphs to a multiline label whenever the user presses the enter key. Eventually the label fills with text so I have to clear the label to continue writing.What I need is a way to find how many lines of text are in my label, so after it passes line #50 I can make the label automatically clear itself and begin writing on line #1 again (as if the user just flipped to the next page of a book).My first idea was to turn AutoSize on and monitor the height of the auto-sized label box. After it passed a certain height I could clear it - but this didn't work because I need the label to be of a certain width.
