VS 2008 : Convert A IP Range String To Base64String For XML Storage?

Jul 14, 2010

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(".")

Jun 13, 2010

I'm trying to convert an ASCII String to hex for VB 2008. So far I have this :

Code:

VS 2008 Convert A String Into A Linq Query?

May 20, 2012

Is there a way to convert a string into a linq query? Searching for those words brings up tons of stuff unrelated to what I'm trying to do..For instance, this works, of course...

Dim lstMyQuery = (From item in htMyTable.values where item(0) = "Apple" Select item)

But somehow I want to do this:

Dim strQuery = "From item in htMyTable.values where item(0) = " & CHR(34) & "Apples" & CHR(34) & " Select item"
Dim lstMyQuery = (Somehow run/convert strQuery as a query)

The reason is strQuery will be different each time depending on what the user has selected earlier in the program.R if lstMyQuery is already a collection, is there a way to add to it?

Dim lstMyQuery = (From item in htMyTable.values where item(0) = "Apples" Select item)

(this obviously doesn't work, but it's basically what I want to do...)

lstMyQuery.Add(From item in htMyTable.values where item(0) = "Oranges" Select item)

VS 2008 - Failed To Convert Parameter Value From String To Int32

There is a relationship between country.country and customer.country. I have made country a combo box with the contents of country inside it. This problem is resolved if I remove country as an input - but I need it in!

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"))
