View 2 RepliesI'm writing a program to search files.The result is saved in a text file.Everything it's working fine, but when I say to look for files/folders in C:* the process takes long time and in task manager it's displayed as "Not Responding", this is not true because I see that CPU and RAM are working with this process.I've disabled in DEBUG OPTIONS the line "ContextSwitchDeadlock" just to prevent the error message "this operation require long time ... bla bla bla".Is there any way to display a progress bar or something like that that shows the program is running and it isn't "hang"?Here's my code (in red the line where the program hangs):

View 11 RepliesI am writing an application for managing mp3 files. I use AXWindowsMediaPlayer1 for playing files and UltraID3 for reading and writing ID3 tags. Every time the user selects to switch to next song, the ID3 tags of the current file need to be updated. My problem is with Media Player taking a long time to release a file for access after doing a "close". Currently I need to add a 6 seconds delay between the "Close" method of the media player and the ID3 tag "Write", otherwise I get the error saying that the file is currently in use. Anything less than 6 seconds does not work...

Simple question, what would be the optimum code in VB2010 to read in a text file and verify that:1) It is a text file, and2) There are no non-ASCII characters anywhereAnd conversely, we would want the code to provide a warning if the file is not a text file, or if the text file contains non-ASCII characters. [Note that LF, CR and EOF are expected to be in the text file, and should not be flagged as errors]

It has beenused successfully a 2 stores since 2001 (with updates of course).I would like to convert it to VB2008 (although I know about VB "fusion") just to keep it up to date and modernize it a bit.Since using the VB converter brings up such a lot of junk, I'm rewriting each module and form from scratch (although using as much of the original code as possible).
