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?
I'm at present looking at various ways on how to convert files without any extension and making them with a .txt extension. At present, I'm using the RENAME feature within windows to do this, but i takes time when there are a lot of files to rename. Can anybody give me a few pointers on how this can be done using Visual Basic?
View 3 RepliesI have a program that processes files in a special subdirectory and the program processes the files based upon the "Type", i.e., "Text Document". If an application, such as a text editor, installed onto the system, the "Type" may change to suit that application. For example, I recently had one change the type from "TXT File" to "UltraEdit Document (.txt}". Yes, the squirrely brace was on the end, don't know why. Well, after this app was installed, my program found no files of "TXT File" type to process even though the subdirectory was full of filename.txt files.
So, how can I get the code to look at the file extension, not the Type? A few lines of the code are shown:

View 8 RepliesWhy 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 want to delete some files but only if they aren't in use. What i did was a try/catch:
Try
My.Computer.FileSystem.DeleteFile(fileInfo.FullName)
Catch ex As Exception
End Try

Is there an faster way to delete files? Is it faster to check first if an file is open? If yes, how can i check if an file is open?
