(I have cut out a section where it tries to write it to a doc file. (just the writting))What I was wondering is how would I improve several parts of this code?
1. The speed - Already In a background worker (I will write a delegate soon )
2. The chars that can be used with it because this only allows the preset ones I would like to be able to use other ones like � or Chinese chars etc.
3. general Code.

View 2 RepliesI am trying to verify that a string contains nothing but known values. In this case, I need to make sure it contains only "Shift", "Control", or "Alt", but not necessarily all of those. For example, these should be true: "Shift + P", "Shift + Control + H", "Alt + U; but these should not: "Other + P", "Shift + Fake + Y", "Unknown + Shift + E" etc.This is the code I tried to use:
If Not shortcut.Contains("Shift") Or Not shortcut.Contains("Control") Or Not shortcut.Contains("Alt") Then
MessageBox.Show("Invalid")
End If

I am very new to VB, and am programming in VB 2008 express. Sorry if this thread is in the wrong spot I need to add two 40 digit numbers together and was thinking that the simplest way to do it would be to input them as a string and then convert the string to a single dimensional array where x(1) is the 1st digit in the number, and x(30) is the 30th digit, etc. I would do the same for the other number where y(1) is the 1st digit. I would then add the x(40) and y(40) (which are the last digits of the number) together and carry the remainder into the next addition (39th digit, 38, ...)

I have a tblVersion that contains the versions of my application:
VersionID Version
VersionID is a bigint primary key, version is a ntext column that holds the current version... I want to be able to pick the row that has the highest version number, but version could be in this format:
MyApplication 1.0.1
If I try to convert that to a int32 it will throw an exception obviously. I would like to know if some of you have a idea how to solve this issue. I could of course make sure the column will only contain numeric values but this gives a little more flexibility.

I am having a string in CSV format.http:[code].....I can add new values to it by some mechanism. Everything will be same except the new values will have numeric part = 0. Take example I have this exsiting CSV string
1 , abc.txt , 2 , def.doc , 3 , flyaway.txt
Now by some mechanism i added two more files Superman.txt and Spiderman.txt to the existing string. Now it became
1 , abc.txt , 2 , def.doc , 3 , flyaway.txt, 0, Superman.txt, 0 , Spiderman.txt
What i am doing here is that this csv string is paased into SP where its splitted and inserted to db. So for inserting I have to take the files with numeric part 0 only rest will be omiited .Which will be further then converted into CSV string.Array will look like this
str[0]="1"
str[1]="abc.txt"
str[2]="2"[code].....
So at last i want to say my input will be
1 , abc.txt , 2 , def.doc , 3 , flyaway.txt, 0, Superman.txt, 0 , Spiderman.txt
Desired Output:
0, Superman.txt, 0 , Spiderman.txt

"video_id": "value 1 here"
