VS 2008 : Getting Only The Extension?
Jul 14, 2009
I'm making a program where I'm separating the file path and the file extension. The path will be held in one list box and the extension in the other.Right now all I'm trying to to is get the extension since once i have that, i can just take away the extension from the whole string (once i know what it is) and then add that to the other listbox.
VB.NET
With OpenFileDialog1
.FileName = vbNullString
.Multiselect = True
[code]...
The place in that code where I'm trying the get only the extensions is:
"Name_and_Ext.ListBox2.Items.Add(IO.Path.GetExtension(OpenFileDialog1.ToString))"
That code only works if you have one item selected and since my openfiledialog has multiselect enabled, it needs to be able to do however many are selected.

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..."?

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?

I saw this post and I want to know if this is possible in VB. So like extension method, do extension properties exists in VB.Net? Here I've read they do, but cannot find any examples.

I 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? And another question, how could I make a file extension that would act like a folder? Like store images and sound files and things like that.

I got an easy one this time How can I get a file knowing the path and the name of it, but not knowing the extension which I need to get. You can see at the moment I use this silly code which finds and opens some main filetypes for me, but if I could get hold of the file extension just by using the filename and the path I could open any document or image...

I have to read SGI Files (I belive it's Suns Raster Image files, they have .rgb extension,but contains no header information), scale it, rotate it and maybe apply anti-aliasing filter to resampled image.I am just trying to read the image file. I read the file in byte array using FileStream and trying to display it in a image box, but it is throwing error while creating Bitmap class from the byte array. My code looks like this:
csharp
string imgpath = "Images\sample1_400x400.rgb";
System.IO.FileStream fs = System.IO.File.OpenRead(imgpath);

I have found that to get part of my program to do what i need it to do without causing proplems is to remove the file extention, do what needs to be done with the files and then put the file extention back.

I wrote some string extension methods in a VB assembly and am unit testing them from a C# project. However, C# acts like it cannot see the the extension methods, when other VB projects reference the VB assembly they have no problem. Both the VB assemebly and the C# test project are targeting .Net 3.5. Is there a way around this?

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.

I 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.

How 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"

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?

Using the below code I want to set the '*' to any file. This folder (C:ewtemp) will only have one TIF file in it at a time so I want it to use that file as TextBox1, but that filename is dynamic, but always with extension .TIF.
TextBox1 = Convert.ToBase64String(StreamFile("C:
ewtemp" * ".TIF"))
Know how to do that?

I am having problems with CodeDomProvider. When I compile a code VB, there is not an error. But, if this code has extensions (ex: string().contains(), char().count, char().AsEnumerable, etc.) at the moment that I call these functions, it's returns an exception equal for all these extensions:
'Public Member 'Count' at type 'Char()' not found'
'Public Member 'Contains' at type 'String()' not found'
Dim refs() As String =
[CODE]...
These are the Assembly that is referenced to the compile, and this is also configurated for run in Framework 4.0.
Dim Param As New Dictionary(Of String, String)
Param.Add("CompilerVersion", "v4.0")
Dim oCodeProvider = CodeDomProvider.CreateProvider("VisualBasic", Param)
This code is inside a string:
Imports System
Imports System.Xml
Imports System.Data
[CODE]...
After I use it for compile my Assembly. The code compiles without errors, but when I call the function 'ProcessarLink', it returns me the exception in 'Contains', or when I call the function 'Personalizar' the errors appears with the 'Count'. This happens with the others extensions too, like AsEnumerable, etc.

I have a need to create a Tcl extension that calls a managed .NET DLL/Class Library. Currently, the structure of my application is Tcl > DLL Wrapper (C++ CLR) > .NET Class Library (VB.NET), where ">" represents a function call.
My VB.NET DLL just takes a value and returns it back, keeping it simple for now. In the end, this will do some more advanced stuff that makes use of some .NET functionality.
Public Class TestClass
Public Function TestFunction(ByVal param As Integer) As Integer
Return param
End Function
End Class
My Tcl Extension (C++ CLR) creates an object of the type above
int TestCmd(ClientData data, Tcl_Interp *interp, int objc, Tcl_Obj *CONST objv[])
{
// Check the number of arguments
[code].....
If my VB.NET DLL is in the same directory as my extension DLL, the extension crashes when it instantiates a TestClass object. I've noticed if the VB.NET DLL is relocated to C:Tclin, the extension will find it, and TestCmd can be called just fine. The problem is that this will eventually need to be deployed across a number of PCs, and it's preferred not to mingle my application's files with another application's.

Unfortunately the compiler is giving a 'Cannot resolve symbol' error for 'DoVB()' and highlighting it red.Yet it will recognise the call in a static fashion.

I want more customization then the original VS 2010 set up files. So i decided to code everything. For example, i put all my files in my debug folder into my installer.vb's My.Resources. So i usedSystem.IO.File.WriteAllText ---> to install all my files and the .exe one.Everything was installed it except my Ethup Bolt New Build.exe. It shows up in the folder after installation, but when i click on it, it didnt run at all. (It showed up in the task manger, under process, but it disappeared after like 5secs.) So it didnt
run at all. My question is how do i install my .exe properly. ( I DONT WANT TO USE THE ORIGINAL INSTALLER WITH Visual Studio)
