Read Part Of A String In A Conditional Statement?
Aug 29, 2009
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.

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 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:
Private Sub CheSMS()
Dim SQLServer As String = My.Settings.SQLServer

I 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.

Okay so I need some help with radio buttons. Basically what I am looking to do is make an "If...Then" statement but it needs to know which radio buttons were selected to finish the "then" part of the statement. What code would I use to do this?I don't really want a spoiler, more of an explanation of how it actually works also.

Just wondering if its possible in VB.NET RegEx's if you can do conditional substitutions when rebuilding a string, in the sense that extra characters can be inserted if missing. I offer this bank account example, were we're trying to standardize a bank account into the format XX-XXXX-XXXXXXX-XXX, note the 3 XXX's in the suffix

I would like to invoke a click on a link from a link that is generated by an HTML query. I am attempting to program an application that queries a website and am getting hung up where I download the .csv that is loaded by the website.[url]...
cansim9170974256855749928 from the url is not static and I don't know how to work around this. I thought that this link would be helpful and should be except there is no link ID to reference. Is there a way to enable a clicking event on a random csv link? I have mashed together some failing attempts at this off and on for some time now and am now in your hands.

I want to be able to read ONLY the link from the file.. In the first file above it would be after the "File1=" text in the file.. And in the other file it should be whats written after the "<ref href="" part..
And as you see in the second file there are three links, so to start with it should only read the first line, maybe later i could make a selection window popup or something..
