I am developing an application where I have a file url such as
"C:/Tom/Says/Hello/file.txt"
I have in the past removed the directory from the string to leave me with "file.txt", but this time the directory may be different so I cannot just take away "C:/Tom/Says/Hello/" from the string. How can I get rid of the directory location and just leave me with "file.txt" when the directory will be different everytime?
I got a error when I run this code:
Dim btch As String
Dim LeftPart As String
[CODE]...
It says index and location must refert to a location withing string
I've been working on some code to rename files and have being doing so by copying them to the same location under a different name and then removing the original. When I do this for files I use the code ...
Dim file As New System.IO.FileInfo(lstFiles.SelectedItem.ToString)
Dim strNewFile As String
Dim strRename As String
Dim strMask As String = ""
[code]....
This will obviously not work as it will try to copy the folder into itself which is not allowed.
How can I get the location of the physical root directory of my website in VB.Net?

I am trying to copy a directory with sub directories and files to another location on my computer. Whenever I try, I get the following error, through my "console":

I am trying to write a simple Visual Basic 2008 installer that copies word macro templates to Word's startup directory. On Vista and 7, that directory is the user's AppDataRoamingMicrosoftWordSTARTUP directory. Is there a way that I can programmatically find this directory? I.e. is it safe to say that this directory will almost always be in this location such that I can simply get the user's home directory and then add AppDataetc.... or is there a registry or something else that I can access to get Word's current standard startup directory?

My program toggles an existing IE add-on between enabled and disabled. At the same time, it creates a shortcut to itself in the Quick Launch folder using one of two icons which reflect whether the next click is a toggle on or toggle off. I store the two icons in the same folder as the targeted executable, and everything works fine, but I would rather have these two files embedded. I know how to embed them. The problem is locating them. At the moment I use:
Dim MyShortcut As IWshRuntimeLibrary.IWshShortcut
MyShortcut = WshShell.CreateShortcut(QuickLaunchVariable & "Toggle.lnk")
MyShortcut.TargetPath = path/executable
MyShortcut.IconLocation = path/iconfile
MyShortcut.IconLocation requires a string and I don't know how to get to the location of an embedded file as a string. There is no MyShortcut.Icon which would allow me to simply refer to the embedded file.

This is my code, it doesn't work when I copy into form load. But when I try it in another form, it works. Index and count must refer to a location within the string. Parameter name: count
why this error happens with a bit of code i was trying? The code is actually intended to be for an onclick event, so it actually works there.
But im just curious as to why it errors as an onchange event. This is 9am pre-caffeine, so the reason is probably starring me in the face! On a form i have a text box, and a combo box. The combo box has various options in it, natch. Its a search form, which then fills a gridview with the results.
Drop down list options are: home number, mobile number, post code, Name, DOB
I thought id try and be "clever" and do away with the need for the combo box. Since a mobile number begins with "07", names are just characters, postcodes are character character number, and home number is all numbers and doesent begin with "07", and date of birth has /'s in it.
So i tried this to test the idea:
Private Sub AppSearchTB_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AppSearchTB.TextChanged
Dim TLength As Integer = 2

I am trying to get the first 50 letters, so I used the subString function to get it. As you can see, I used this code to get it:
<%# Eval("BannerDescription").ToString.Substring(1, 50)%>
But unfortunately it's not working and an error message is coming up:
Index and length must refer to a location within the string.
Because the user is the one who is controlling the data entry! Some times he gonna enter 10 letters other times maybe 1000 letter?
I tried them all but can we use it this way :
<%# IIf(Eval("BannerDescription").ToString().Length > 49, Eval("BannerDescription").ToString().Substring(0, 49), Eval("BannerDescription"))%>

View 4 RepliesAfter a little research, I managed to get a working Help button added to my form. I did this by setting the MinimizeBox and MaximizeBox properties of the form to false, set the ShowHelp property of the form to true and added a HelpProvider component. I then added a string to each control's HelpString property that I want to display help on.
Everything works with one minor exception. When I clcik the help button in the form and then select a control, the HelpString (tooltip) is displayed in the far lower left corner of the screen. I assumed I would see this pop up at the cursor rather than where it is. I cannot seem to find a property to control the position of the HelpString popup.
trying to determine the index of a child node using the key string so I can add a new child node to it.I am using this code:

But only works for the root node when I try to find an exiting child node the code returns -1 (Not Found)
I keep getting the error saying that index and length must refer to a location within the string.
