I am trying to make a programming language and cant figure out how read the part of the string I want in a conditional statement. Ive tried this:
If (syn_(0) = "p" & syn_(1) = "u" & syn_(2) = "t") Then
'code to do
End If
But It comes up with an error. IS there any other way because I don't want to have to come up with syntax that is all the same length.
in my text file i have two part. Called bottom and top. So i need to read the Top part first then and match the line with bottom part. Its like this

Quick question, of which the quickest and easiest answer may well be to rearrange related code, but let's see...So I have an If statement (a piece of code which is a part of a full working solution written in C#) rewritten using VB.NET. I am aware the VB.NET IIf(a, b, c) method evaluates both b and a regardless of the trueness of the first evaluation, but this seems to be the case in my standard construct, too:
If (example Is Nothing Or example.Item IsNot compare.Item) Then
'Proceed
End If

I want to display an image if 2 conditions are met. The data item is not null. The value of the data item is greater than 0 Markup

I created a sql query to check if the mobile number is registered or not. If its registered, it will send the new pin code to the customer and if its not, the customer will get a message that "This number is not registered or you are not authorized to this"... something like that... Sending of new code is already working. I just dont know how to make it as conditional statement like PHP. After you query on PHP, you can just set a variable and make a conditional statement..Here is my script in vb.net:

View 4 RepliesI need to parse and separate input strings using VB.NET. Split method works in Example 1, but my problem is when I need to "skip" a space if the following value isn't in the list like Example2. My code works as expected for String1 using Split, but it fails my needs when it outputs EXT1000 and 3 as individual values - they should be part of the original string if not found in the list.I would prefer to keep it in Linq if possible. Generate some type of collection to be used for later manipulation. The main output will end up with a For Each "Results" WriteLine in text file.
