Hello ,
I am trying to manipulate the string
Dim str as string = "YS3EB45E833005745_20050610_WINDSHIELD"
Now i just need the part that is in between the two underscores. That is in the above string i just need that part 20050610.
I am trying to remember the function that i had used to identify the occurances of a particular character in the past.
Can any one help me with this?
Thanks

you can use string.split() and it will be the second item in the returned array.

Could you please elobarate on how do we implement this in my case?
Thanks

Yes this works here is what i did off course the same
Dim MyString As String = "YS3EB45E833005745_20050610_WINDSHIELD"
MySplitLine = MyString.Split("_")
MessageBox.Show(MySplitLine(1))
and its returning 20050610
But like you mentioned .ToCharArray()may be an efficient way of doing it.
we need to use ToCharArray() because we are splitting a string?
Thanks

No, I use it for documentation purposes, it is more clear what the code is doing, imo, when I see tochararray(). That being said, I recall I may have had issues when I had a string longer than one charater. Nonetheless, your code returns the correct results, so at the end of the day, our code is managerially equvilant

Although many people will argue this point to death, I feel efficent is only releveant in the 20% of the code that does 80% of the work in the program. Most of a program is scaffolding to support the core logic, anyway. Therefore, who cares if some ui element take 20 extra ns to complete. The user cant tell the difference! 80% of the code should be simple and readable 20% (that which does the work) should be "efficent"

Sure i like your arugment. If the code is more readable and understandable it would be easy for another developer who comes in after we left. I agree with you
thanks

If you would like the code to be more efficient, you should get rid of the Split all together (as that creates at least two strings that you don't even use). Use IndexOf to locate the first and second "_" in the string, then use Substring to get the part of the string in between.
Still I agree with Jason's opinion that most of the code doesn't need to be optimized to the max. Consider how often the code will be used, and how much resources it uses compared to the surronding code.
Simple code that works is always better than optimized code that doesn't.

Good explanation and thanks for the reply. I am excited trying the same thing in different ways and figure out the best option.
Here is how i am trying to get the index of the string i posted in my string YS3EB45E833005745_20050610_WINDSHIELD
Dim indexOf_ As Integer
indexOf_ = fileName.IndexOf("_")
the above one gives me the index of the first occurance of the "_". How do i get the second occurance of the "_" and then use the substring?
Thanks for the reply,

You can use either LastIndexOf("_") or IndexOf("_", indexOf_ + 1).
For Substring you need the index of the first character and the length.
The first character is located at indexOf_ + 1.
The length I believe is the index of the second _ minus indexOf_ minus one.

I think you want to show something on form2 based on a value passed from form1, if thats rigth, just add the following code to form2
'Val can be any name and any type
Public Overloads Sub show(ByVal val As Integer)
'Load your custItemsDataSet or assign Val to a local variable or do what you got to do to load your dataset
Me.Show()
End Sub

Background: I have a number of PC's (XP) that i have on remote sites and i want to write a piece of software that will back them up to my server to save me the time from going to do it manually every week!
What I want: Guidance on what i should be doing! I am a relativly new developer in vb.net(2003) and would like some pointers in the right direction.
Cheers

A question rather then advice, why are you building a wheel that already exists. There are many remote backup systems out there but there are $$$ involved.
What do you have to backup, or more importantly how big is the backup? What damage will it do to your WAN.
That said here is what I did to backup several servers under my care back to head office.
Step 1: Schedule MS Backup to run at a time that suites (for me 6pm Friday)
Step 2: Write or Script WSFTP (or most other FTP apps) to pickup the file and send to you.
I backup system state and local stored files plus grab SQL db from 2 servers.
As I could not be sure of how long the backup would take I start the FTP two hours after the backup. Size is the biggest prob as one server has 5 gig on it and this takes time even with a fast pipe
I know it is simple but sometimes that is the best.
If your desire is to code the start with the FTP app I have written a few and they are OK if you keep it simple.
Backup, compression, checking file states, handling system files can be very difficult
Hope this helps...
When people make you see red, be thankful your not colour blind.

Many thanks. We are looking to roll the app out as a stand alone serviceto a handfull of our home clients too and was hoping we could produce a simple package that they could setup themselves.
We have 20 machines to backup for us and have storage to take on about an extra 200 desktops.
I don't mind spending a bit as we will be charging them for the space on our servers to help us cover our new pipe!
Your solution would be usefull to us for our pc's but not the other.
Cheers for the quick reply. If you have any suggestions please fee lfree to send them on
Regards
Denis

Hi,
I am trying to create a dropzone form which is completely blank (No controls) so that I can drag and drop any file from the desktop onto the form which then moves the file from the desktop to the directory c:\dropzone
All I can find so far is drag and drop with controls not just the form.
Can anyone help with the VB.net code ?
