In this column, values are like 3101,3102, 3103........Here 31 is the common. and like 3201,3202,3203......Here 32 is the common. Like there are so many common values are there. So where ever the common values will come there i have to add one button in the Same column.
So Finally my conclsion is at Satrting 3101 and starting 3201,3301,3401.. i have to add one button control 3101 and add button control on 3201 and add button control on 3301.
Can someone give me a site to a tutorial that will help me write a program that will generate a pattern using do while, if else statements,and do until statements.

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.

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]
