The batch section should generate a new random value and write it every time it do the loop, but...It is repeating values. There are more than one line with the same value. What I'm doing wrong?
Crystal Report is repeating values like this:
1 rar
1 rar
1 rar
1 rar
1 rar
I want the output to be like this:
1 rar
I wrote code like this:
Dim crParameterFieldDefinitions As ParameterFieldDefinitions

Dim crParameterValues As New ParameterValues()
Dim crParameterDiscreteValue As New ParameterDiscreteValue()
crParameterDiscreteValue.Value = Label1.Text

I'm working on a Bingo game that generates a random letter and number.
Dim RandN As New Random()
Dim randnumber = RandN.Next(1, 30)
Dim RandL As New Random()
Dim randletter = RandL.Next(1, 5)
All that works, but I'd like it not to repeat a combination. Any tips on how to do that?
Also the random numbers tend to be repetitive and the random letter is never 5. I think the random number has been 30 before but I can't be sure. Is there a way to fix that or just a better way to do the random numbers?
Ok im making a program that throws three dice at once. Several results end with a score but a few result in a no score. in the case of a no score (Example: the dice land on 4,1,6) i want the dice to be thrown again. If there's 3 no scores in a row then it counts as a loss.I have no clue how to get it to repeat after a no score or to limit i
Current code sample:
Dim oppscore As Integer
Randomize()

I am writing a matching program, and need 24 objects to randomly appear, each twice, across 48 spaces. I figured the best way for me to do this would be to assign the positions a number 1 through 48. but the problem is I can't find a way to generate a random number sequence in visual basic 9 .netI found many examples in visual basic .net but the conversion doesn't work. If not some code, many some example programs that either use a random number sequence or randomly sets the position of objects.

Is there a way to use the string.split command to get a section of a string without using an intermediary array?for example, if my string is "1 2" and I want to get the "2" part using string.split(" "), is there a way to avoid creating a new array, and just get the bit of the string I want in a single line?
View 4 RepliesI have built a blog platform in VB.NET where the audience are very young, and for some reason like to express their commitment by repeating sequences of characters in their comments.
Examples:
Hi!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

..and so on.
I don't want to filter this out completely, however, I would like to shorten it down to a maximum of 5 repeating characters or sequences in a row.I have no problem writing a function to handle a single repeating character. But what is the most effective way to filter out a repeating sequence as well?This is what I used earlier for the single repeating characters

I have a networkstream (using C#/VB.NET). while on reading values coming like this:
&% 68 kg K A&% 23 kg K A&% 174 kg K A &% 68 kg
&% 34 kg K A&% 2334 kg K A&% 68 kg K A &% 68 kg K A
&% 2348 kg K A&% 78 kg K A&% 28 kg K A&% 68 kg
The numerical(weight) value will be continuously varying.
Every time i am reading the starting of the stream differs. But the pattern remains the same. How to split that into '&% 78 kg K A' which represents one set.
How to extract the weight value from this stream using Regex or any other methods?

I am parsing a file that has a section between the separators that is 40 characters long. I need to split this into 20 separate strings which will each represent a data column. While already in a FOR statement, I think it would be best to also use something like
items(x + 4)
For y As Integer = 0 To items.GetUpperBound(0) Step 20
RR(y) = ' CHAR 1-2, then 3-4, then 5-6, then etc.
LR(y) = ' CHAR 21-22, then 23-24, then 25-26, then etc.
Next
E.g. C67FCBC67FBCB7BCCBC6CB7FD0CB7FBCBCBCC6CB
What these are is the values of a hearing test result starting with the Right Ear 1-20 and Left Ear 21-40. Before writing it to the DataTable I will then send it through a function to translate it to decimal like Translate(LR(y)) or something like that.
In a test project, I am attempting to fill 10 different text boxes, named tb1, tb2....etc with the following code with a value between $00.00 and $99.00.

What am I overlooking that prevents this from generating a new value for each text box?[code]...

What boggles my mind is that this all works fine in my C# console test app after I convert the code from VB.NET using a web utility. However, when I paste the VB code from my web app into my VB.NET console test app, it doesn't work there, either, so it appears to be a C#/VB issue. What am I doing wrong here?
The exception message I am receiving is this... "Year, Month, and Day parameters describe an un-representable DateTime."
Now I've traced my values being passed and everything is correct. Values loops through 1 to 12 but still I continue to receive an exception. Only way I can avoid this is by throwing a Try, Catch statement around where I'm passing over the value.
Here's my code..
001 Dim Calendar(11) As AppointmentBookControl.AppointmentBookControlMonthlyOverviewCalendarControl
002

Line '011 .Month = i+1' is where the problem is located. The values for (i+1) maintain within the bounds of 1 through 12..
I've made a function in C# to create a random string, but I wanted to convert it to VB.NET, unfortunately my knowledge of Visual Basic is much less than my knowledge of C#.
Here is my VB.NET function:
CODE:
As you will see, its not much different from my C# version, except that since VB can take an optional parameter, I allow the user to select what characters to use in the string, or just use the default ones.
Here's the C# version of my function:
CODE:
Again, there's not much different, but the part I'm really struggling on is the conversion between what is the 12th line of VB code, and the 13th line of C# code. I didn't really know how to convert it to VB.NET (as I said, my knowledge of it is very limited), so I used an online converter. The result of the online converter runs with no errors, however when I try to call the function, no string appears.
In short, this C# code works fine:

However, this VB.NET code doesn't work:
