View 2 RepliesI found out how to create file extensions on my PC and I want to open my program with the file extension, but how would I be able to load the text in the file extension into a textbox on my form if that's what the extension is for?

I am having problems downloading files possibly due to the file extensions not matching the actual file. What is happening is the File.Exists check is returning false for these even though the named file does exist. Is anybody aware of anything in IIS or even IE which would cause this? I have seen this with .txt, .exe. and .avi files. The .avi works of as long as the file really is an avi and not renamed from something else.
View 2 Repliesi just made a small notepad type program. The function for opening and saving are working perfectly but i want it so that i could save the ".txt" as my own filetype lets say ".tox" or something.
View 1 RepliesI don't really know how to use compression in VB.net, so I was wondering if someone could explain it to me. I'm also wondering if it is possible to create a compressed file with your own extension.
View 13 RepliesHow would i go about checking a file extention to see if it is either
'.exe' or '.ex_'
What i need to be able to do is that if the extention of the file is '.ex_' then that file is copied to another folder, or if the file extention is '.exe' then it is passed onto another routine that will compress is.
Baring in mind that there could be a number of files in that folder.
I already have a routine that will compress the files, just need the above.
I am looking for an advise on how to find out the extension of the file only knowing the name and the location of it. I tried getextension method and some other but they don't seem to do anything to me.
E.G.:
Dim FileFullPath As String = "\SERVERPublicCRM_LibraryOrderMGMLetters" & datagridLetters.CurrentRow.Cells.Item(0).Value.ToString() & ".pdf"

If i have an extension ... say...
vb
<System.Runtime.CompilerServices.Extension()> _
Public Sub Invert(ByVal b As Bitmap)
is there any way of hiding this from inteli-sense if it is not used as an extension?so that pressing ctl+space only triggers it if you go "bitmap.Inve.." rather than prompting on "Inve..."?
I am using VB 08 running an openfiledialogue wanting to get the result of the GDS file (*.gds) to be the default extension at the drop down menu instead of All file when the openfiledialogue box opens.
I coded it with:
OpenFileDialogue.Filter = "GDS File(*.gds)|*.gds|All files|*.*"
but the results i get in the open file dialogue box remains as all files being in the drop down menu as the default file extension. How to i set it to ".gds" format?

Why would I use an extension method instead of just creating non-extension sub or function?
For ex, I could have an extension function called IsNullOrEmptyOrAllSpaces on String, which does a check as its name implies. Or I can write a stand alone function that does the same thing. Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?
