How would I take the location of a file that a user has opened and save it to a string? Say the user opened the file picture.jpg @ C:picture.jpg. How could I save that file path or assign it to a string?

c:me.jpg
i need to return the ".jpg" to a string. Im sure this is easy enough, im guessing i need to get all the text after the last .

Return _Phone

I'm looking for a way to specify the location for the User.config file that is used for storing the My.Settings object. It appears that this is not possible. The problem for me is, I don't want to be responsible for creating several different files on the users computer that really have no use and are difficult to find and clean once an update is released. For most users, this is not a serious problem, as many will probably never update the software, and most will probably only go through a couple of updates. On my system, there are config files for every build of the application, and the same to a lesser extent will be true for my beta testers.
I can understand that MS wants to make sure that no two applications will use the same location for storing application data, but a simple [UserData] [CompanyName][ApplicationName] for storing application data will probably suffice for 99.9999 percent of the legitimate applications in the world. Bogging a user's system down with erroneous files, no matter how small, is an unnecessary drain on system resources and a potential source of problems for the user. It's bad enough that most programs leave bits and pieces of themselves all over a user's system after De-installation - this to me seems only to exaggerate this problem.
Is the only way to get around this problem to write a whole new Settings Class? Is there a way to change the location of the UserConfig file to a more friendly (and more predictable) location that I am not finding for myself? It would seem that having at least the OPTION to specify a location for the User.Config file would be OBVIOUS and easy to implement, so why did they leave this out?

When I save settings for an application using My.Settings.Save it saves it in %AppData%LocalCompanyname. Because I don't want my app to be installed and I want it to be a just .exe file, and it leaves some files on that computer. I like it to be in my apps location. Can I change that default location?

What I am trying to figure out is a way to copy a file and paste it in another location. So that there will be the original file in the user set location, and then a duplicate of that file in, say, the "Program Files" folder. I would also need some way to check if the file exists to, so that it doesn't keep creating a new file each time the program starts up.
to sum it up: I need to be able to copy a file to a predetermined location and check if the file exists, and if it doesn't, it will copy the file over to the location.
I was using this old method of creating a bunch of rectangles when I need to get the location of a certain point within a grid so I could draw images on the grid. The thing is, I don't want to use rectangles, I want to be able to just round the location as if I were using rectangles. I need it to be able to round the point (66,70) to (50,50) so if you can imagine a grid and the mouse position being within that square in the grid, I need to get the location of the upper left corner of that square.

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?

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:

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:
