I wonder if there is a Type that converts a string to a VB syntax to be read by the compiler.
for example:
Dim command1, command2, command3 As what??!
Dim drv as DataSet.Datarow
drv = CType(BindingSource.Current, DataRowView).Row

I used the query designer to create a qry from a datagrid view in vb2010 express, the idea was to work out which diver logged the most minutes in the water. here is a copy of the sql syntax:
SELECT MemberID, Name, SUM(DiveTime1) AS D1, SUM(DiveTime2) AS D2, SUM(DiveTime1 + DiveTime2) AS s1
FROM Triplog
GROUP BY MemberID, Name
ORDER BY s1 DESC

works very well. So seems some consistency miss of the string constant behavior.
2) Have a look on the COMMENTS (in the attached picture). The words "custom", "string" and "error" are highlighted, however they are in the comments, so should be green, not blue.
Why this? What workaround? EDIT: Declared as "bug" in Microsoft Connect (even if is not more that a syntactic "miss")... EDIT 2: As remarked Hans Passant, standard string methods, like "cucu".Trim() does not work either.
I want to do in vb.net what I would have done in SQL with the CHARINDEX command. That is, I want to interrogate a string and ask, 'Does this string contain a hyphen? If so, whereabouts in the string is it?' I tried Googling this but as with a lot of things in vb.net, there's always a million different answers given with each response seemingly trying to overcomplicate the issue and out-code the previous one. Hence my confusion.
View 5 RepliesI am trying an encrypting exercise which takes the txtmessage and encrypts it in characterarray.IStartAt is the starting point and by taking one character at a time from txtmessage I need to insert it in characterarry allowing a gap in between which is IUseGap. KeyGap and Keyfirst will be the next two characters after txtmessage and when insert have no gap in between.I think the logic I done is good however, I get syntax errors on the red lines.[code]

I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.
