the problem is I'm trying to access a file that has no file extension. I think you can see why this is so difficult. The specific file I'm trying to edit is the hosts file (C:\Windows\System32\drivers\etc\hosts).

The problem is that if I save a file I get "myfile.GDL" if I overwrite that I get a new file "myfile.GDL.GDL" ect.the other problem being that the filtering in the windows save/open dialog wont show .GDL files unless I select "all files".
Is there a way in VB to copy certain file types comparable to the commnad line copy command

What I would like to do is expand the filter to include alternative file extensions (i.e., ".rar", ".7z", etc)
How would I loop through a directory recursively, and get a list of ALL file extensions used, not duplicating any of them? It could just output to the debug window. Or perhaps write to the database and have the database filter the duplicates. So it would be great to see...

I'm trying to delete all the files in the same folder that have the same name but different extensions, such as CurrentWallpaper.bmp, CurrentWallpaper.jpg, CurrentWallpaper.png, without putting them in a separate folder. How could I go about doing this? I tried doing
Dim bg As String = dir + "" + Login.UsernameTextBox.Text
Kill(bg + "CurrentWallpaper.*")
but it didn't work. PS: I would also like to use the same technique for loading the image as a background image instead of having to do this:
Try
If My.Computer.FileSystem.FileExists(Login.UsernameTextBox.Text + "/CurrentWallpaper.jpg") Then
Me.BackgroundImage = Image.FromFile(Login.UsernameTextBox.Text + "/CurrentWallpaper.jpg")
End If

I have certain files that need deleted every time I run my program. There are some files that start with f. and then end with .00000668 or .00005396 and so on. Here is my coding that is not working to delete the f files.

I'm writing a program that allows users to view certain files using a DataGridView as the selection method I can do most of that just fine. Here's the part I'm having trouble with: I want to open the files using whatever program they have associated with the file extension. After researching it (on these forums), I determined that I should use the Process.Start() method. However, Windows throws an Win32Exception if there is no association to the filetype, and I want it to show the "Open With" dialog instead, and I can't figure out or find how to do that.

I'm using the FileSaveAs dialog control to allow the user to select a filename to save a file either as a doc file, an rtf file or a pdf file (that part was easy).However, after a bit of testing, it seems that the file extension doesn't automatically change when selecting the different file types.If the filename in the dialog is Foo.doc and I select FileType *.pdf and click "Save", my app still tries to save the file as a doc type.Virtually every other MS app automatically changes the extension to match a selected file type from the Office Suite to Paint. here's my code:
Dim dlg As New SaveFileDialog
dlg.InitialDirectory = m_sReportFolder
dlg.FileName = sProjectName & ".docx"[code]......

I get how to do it, and i have been to [URL] before. My question is about what doing that does, is it possible to reverse it? What if you do not know where your program will be, and you are just testing it for now? Is there any way for it to "find" your program, or an easy way to edit where it is opened? For that matter, is it possible to tell if the file has been associated already, is it an issue to try and reassociate? Finally, how can you set the .ico file it uses?

I'm getting an "Illegal characters in path" error. How can I fix this?
Basically, I want to be able to say: here, I want to be able to chose my drive (in this case C:) and i want to be able to get the following extentions: .txt. Also i want it to list ALL .txt files in the C drive in either a textbox or listbox.

Path = "C:"

And For Each FoundFile In My.Computer.FileSystem.GetFiles(Path, FileIO.SearchOption.SearchTopLevelOnly, "FILE*.09")
'do code
Next My goal is simply to search for multiple file extensions. I cant use FILE* as my search parameter as this returns other files e.g FILE2012.10z which i don't want.
How can I filter on multiple file extensions when using IO.DirectoryInfo.GetFiles?

I have a program that is getting pretty big and it is a pain to find everything through all the functions and classes. I am trying to break it up into other files based on their method. Some of these functions have calls to others in the main class. I changed most my functions from private to public to access this. I had problems calling certain code created windows so importing mainwindow helped that. My last problem is editing the mainwindow ui from one of the module files. I want to make sure im on the right page before i continue breaking it up. My only guess is that anything they updates the ui should be left on the main class.

View 7 RepliesInside the program I have a text box in which a user puts in the filepath to a textfile that the program then uses as a series of commands to perform tasks. This works perfectly, however what I would like to to do to make my program faster is associate the file extension .gam with the program, so when a user clicks a .gam file it opens the program and automatically sets said file's location into the text field, as opposed to using the browse button I added and browsing to said file everytime they run the program.
Through this a user could then make a shortcut to said .gam file and run it right from their desktop, as opposed to rummaging around in folders and whatnot. At the moment my method has been thus, I have 2 folders of importance I have archived with the .exe, Gambits Pro.exe, these are: Gambits, and Control, inside of the Gambits folder is the default storage location for .gam files, as when you click the browse button its default directory is that folder. I have also added a few example files in said folder for a user when they download the program.
