If there is multiple files with the same name I want to add "_1_" to the end of the file name. If the "_1_" file already exists I want to increment the 1 to be "_2_".

How do I programmatically increment a given version's number to the next version of the highest one?
For example if I have a file Program.exe with the following version numbers :
Program.exe 1.0.0.0
Program.exe 1.0.0.4
Program.exe 1.1.0.76
Program.exe 1.0.0.66
The next version number in this case would be 1.1.0.77
What's the easiest way to implement that?
im working with my thesis, to generate auto increment number. for example,when the form load for the first time it will appear transaction 1, and then next time i'll load the form it will be transaction 2, so on and so forth. i am using a VB.net and SQL server.
View 1 RepliesI have a HFScrollBar on my design page, and a TextBox Right above it. I want the text in the textbox to start at zero, and what I want to do is make it where if i move the scrollbar to the right, it increments that number, and if I move the scrollbar to the left, it decrements that number. I have tried to code this, but realized i was about 1,000,000 miles away from where I am supposed to be lol. So, I wont bother posting what I've tried. A simple straight-to-the point tutorual on this subject would suffice, though.
View 4 RepliesThis feels like a completely basic question, but, for the life of me, I can't seem to work out an elegant solution.
Basically, I am doing a LINQ query creating a new object from the query. In the new object, I want to generate a auto-incremented number to allow me to keep a selection order for later use (named Iter in my example).
Here is my current solution that does what I need:
Dim query2 = From x As DictionaryEntry In MasterCalendarInstance _
Order By x.Key _
Select New With {.CalendarId = x.Key, .Iter = 0}
[Code]....
Is there a way to do this within the context of the LINQ query (so that I don't have to loop the collection after the query)?
i want to update a row in an ACCESS DB in vb.net using sql query. the way to point to the row is using the primary key. the problem is that i was an error saying that there is a data type mismatch in criteria expression. the primary key type is auto-increment.[code]
View 1 RepliesI've been using some recommended code from successfully for a couple of years now to auto-increment the build number in my project.
[URL]
But I just updated my workstation from XP Pro x86 to Vista Ultimate x64 and now it isn't working any more. Everything else works, but not this. It increments the build number when I build the application, but then VS gives the following error:Error 4 Unable to apply this change while debugging. File 'D:My ProjectAssemblyInfo.vb' was reloaded. You must revert the change or stop the debugging session.So essentially I can't do anything in my application, or at least I can't run in debug mode because of the error.
It was very practical to keep build number in VB6, as it auto-incremented that number every time that i "compiled" the program.
There is any equivalent feature in VB.Net? I am using VS 2005.

I have an SQL statement which i need to code in vb:
CODE:
Notice the fields prodno1 and prodno2 in the table structure.. this is part of a number of sql statements i need to run and put inside a loop. my problem is i want to automatically use this same code such that on the next loop, this sql statement is going to be:
CODE:
Note that in this "2nd loop"
- the table name is now r3 from r2 in the first SQL statement
- there are now prodno1, prodno2 and prodno3 instead of just prodno1 and prodno2
- in the WHERE clause, the p.prodNo becomes p.prodNo2
And so on and so forth.. so for the 3rd loop
- there's going to be r4
- there's going to be prodno4
- in the WHERE clause i will use p.prodNo3
