How To Declare Specific String Range
Oct 6, 2009
1. In visual basic 6 when we want to declare a specific string range you use the following format: Dim SZ_ITEM_REF_NO As String * 16
When I checked, like vb6, the code it returned "end of statement expected"
2. When we wanted to have a specific format in the string in vb6 we use the example below:
SZ_ITEM_REF_NO = Format(Adodc2.Recordset!SZ_ITEM_REF_NO, "0000000000000000")
I have the following
myWriter.WriteLine(myReader(0).ToString
I tried to use it like this but it doesn't function:
Format(myWriter.WriteLine(myReader(0).ToString, "00000000000000000000"))

I am trying to declare List(Of String(2)) and it doesn't work
I understood that if I specify the length of the string() the compiler will not need to guess the length and it will be more fast that way, is it correct?

When working with PHP I always declared my string variable and set them equal to null just to be safe. I'm new to visual basic and am wondering what the safest way to declare a string variable is. Will
Dim strWords As String
be sufficient? Or is it better to set it to null or nothing or some other default value or primitive type?

Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)

Been a while since I last posted here. I'm busy on a new project and I need to convert a string which represents a IP range (like this: 10.0.0.0-10.0.0.254), to two Base64 strings which represents the first and second IP adress in this range definition. Like this: (start IP: CgAAAA== End IP: CgAA/g==)I've got it to work, but it such an ugly code, and I know it can be done with 2, or at max 4 lines code. But I'm not so handy with the Base64 string conversion jet. So this is where I ask for help from you guys!
Here's what I got (in goes: Apf.Iprange = "10.0.0.0-10.0.0.254")
Dim StartIp As String = Apf.IPRange.Split("-")(0)
Dim EndIp As String = Apf.IPRange.Split("-")(1)
Dim StartNumbers() As String = StartIp.Split(".")

searching through memory at a given address range, and match a string of bytes specified i.e.
FindArrayOfBytes(Byval str as String, Byval range_start As Integer, Byval range_end as Integer) As Integer
The function should return the address start of where the array of bytes was found.
