View 1 RepliesIn VB.net I've got the following line that removes all non-alphanumeric chars from a string:
return Regex.Replace(build, "[W]", "")
I now need to extend this to remove non-alphanumeric chars that aren't [] or _. I've changed the line to:
return Regex.Replace(build, "[W[]_]", "")
However I'm pretty sure that this says
replace non-word or [ or ] or _
how do I negate the tests for the [] and _ chars so that it says
replace non-word and not [ and not ] and not _
Some examples:
"[Foo Bar_123456]" => "[FooBar_123456]"
"[Foo Bar_123-456*]" => "[FooBar_123456]"

View 2 RepliesI want to create an array of an array (or arraylist of an arraylist) to hold strings.I want to fill an array1 with string values Then add this array to array2. - but only taking up 1 row in array2 e.g something like array2(index)=array1 Then clear array1 then loop through this again with different data, and add it to the array2.so will end up with something like
array2(0)... contains a collection of array1 data
array2(1)... contains a collection of different array1 data
.. and so on
i think i need to make new instances of array1 each loop, but not sure.I dont mind if it uses arrays, or arraylists, or lists, or structure of arrayslists?

I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.

Dim str2 As Array
str = "blabla duhduh"
str2 = str.Split(" ")

If I change the outer loop to:
For Each str() As String In newdata
It builds ok but I don't get what I want. The outer loop process the elements of newdata as a 1d array and the inner loop sees each character of the strings from the outer loop.So...is there a way to use the for each structure and process a 2d string array? If so, what should I change? If not, what is the best alternative?

i have an array of 30 strings , the names of the commands send to the serial port, the serial port adresses 16 devices. each device has its own set of commands.
of course i could make subarrays for each device, but for the saving of memory it would be better to use a integer index to name the commands, so like command 0 to 30.
dim command(29) as array of strings.
dim device(7) as array of devices.

View 20 RepliesThe obvious first thought is:
Public Function CheckStrings(ByVal input As String()) As Boolean
For Each s As String In input
If s.Length > 0 Then Return True
Next
Return False
End Function
I'm sure there is a simpler way than that though. At least simpler in terms of the code if not necessarily the performance.
Here's my final code:
<Extension()> _
Public Function AnyNonZero(ByVal value As String()) As Boolean
If Not value.All(Function(x) String.IsNullOrEmpty(x)) Then Return True
Return False
End Function
