I am a newbie programmer. I have some code that needs to open a file based on what is contained in a variable. Example: If File.Exists(w) Then Dim q() As String = IO.File.ReadAllLines(w)
The problem is that I need the variable "w" , after readallLines , to have a .txt extension. I tried this:
IO.File.ReadAllLines(w & ".txt") but that doesnt work.
I have a couple of pictures in my resources. I know that I can set an image by:
picturebox1.image=my.resource.picture1
But how can I add an image if I hold its name in a string variable?
I need to get the extension part of a file path for example,
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 .
These is the content of my txt file which is saved in D drive in my pc abc,1,2,3..I tried the flowing but it didn't work:[code]I am getting error on this line.. data = line.Split(","c)...it says this line isn't in use anymore or something and that I rather use LineInput but thats asks for filenumber and i don't know what that is. I am sorry but I am a complete beginner. what else can I try? [code]ok that error is gone now but now if I want to add these values to a list box..how can i do that?

View 3 RepliesI 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?

works very well. So seems some consistency miss of the string constant behavior.
2) Have a look on the COMMENTS (in the attached picture). The words "custom", "string" and "error" are highlighted, however they are in the comments, so should be green, not blue.
Why this? What workaround? EDIT: Declared as "bug" in Microsoft Connect (even if is not more that a syntactic "miss")... EDIT 2: As remarked Hans Passant, standard string methods, like "cucu".Trim() does not work either.
I have File Like "Sample.bak" and when I compress it to be "Sample.zip" I lose the file extension inside the zip file I meann when I open the compressed file I find "Sample" without any extension.
I use this code :
Dim name As String = Path.GetFileName(filePath).Replace(".Bak", "")
Dim source() As Byte = System.IO.File.ReadAllBytes(filePath)
Dim compressed() As Byte = ConvertToByteArray(source)
System.IO.File.WriteAllBytes(destination & name & ".Bak" & ".zip", compressed)
Or using this code :
Public Sub cmdCompressFile(ByVal FileName As String)
'Stream object that reads file contents
Dim streamObj As Stream = New StreamReader(FileName).BaseStream
[CODE]...
I need to compress the file without loosing file extension inside compressed file.
This error is exceptionally annoying.I've done various searches, and have been able to fix this issue.I am one of several developers on the application and the only one with the issue. I've fixed it before temporarily by adding an extension to the My Extensions panel in the project's properties (which generates a different error) and then removing that new extension.That made the error go away.
If Not My.Computer.Network.IsAvailable Then
ISConnectedToNetwork = False[code]....
Gives the error:'Computer' is not a member of 'My'.

Recursive File Copy based on file extension. I have a single root folder that contains numerous folders that contain a few files that I want to extract. For this example, lets state that I want to copy all �txt� extensions and put them into a repository folder.
Example:

\root\Folder1\abc.txt

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 have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.
