I've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?

Code:
Dim deleline As String
Dim line As String
Dim isFound As Boolean = False

Ever since I upgraded to Windows 7 Professional I've had constant build problems with VS 2008. I can't use the Hosting Process (not that I normally do) because at build I'll be notified VS could not copy a support file (the hosting exe). In addition, every time I build I'm told my previous exe is in use by another process and cannot be accessed. My only recourse is to manually delete the file. That works a few dozen times but eventually Windows stops letting me delete it and tells me that I require permission from an Administrator to make changes to the file (I'm the administrator,

how would I copy files into a jar, as well as delete folders from that jar. Would I have to decompile it then recompile it? Would sharpziplib do the trick?

View 6 RepliesI've been looking at accessing shared folders, read and write, via the network without being prompted by the OS for the username and password.
On this forum, and googling, I can find many things about accessing network shares, but none using code which also passes the username and password required.
What I'm basically looking for is to not have to map a drive on the users computer. Then using code, write or read files from a network share and at the same time pass the username / password required for that network share.

May i ask you based on your codes last time to create a button, is this how i modify to delete off the button after i clicked on it? So that means to say i click on this button at location 15,41 then only this button will be deleted. the below is my code to delete the button but it is not consistent as sometimes it can delete more than one button when i click on one button.
Dim dr As DialogResult = MessageBox.Show("Are you sure?", "Check", MessageBoxButtons.YesNo)
If dr = Windows.Forms.DialogResult.Yes Then

View 1 RepliesI have a program that uses IO.File.Copy to copy files from point a to point b. Its slow, which is fine because there rather large files. I was wondering if there is way to get an estimate time to copy a particular file(s).
Example: File a will take 1 hour to copy, File B will take 30 minutes to copy. Estimate Total Time: 1 hour 30 minutes.
I am working on a media player, and I would like to setup a local playlist feature. I am using a single ListBox and its "Display-" and "Value-Member" properties. The display is the song's Artist and Name, and the value is the song's file path (i.e 'C:UsersUSERMusicetc.').To write the file path to the .txt file, I believe I can use the following code:[code]

I'm using the SaveFileDialog to save listbox info into a text file. The files save fine, but when you go to save the file, if you hit the cancel button, it will overwrite the previous file you saved, because it's name was the same and it seems to save the previous file as the new name for your next file. Is there any way to catch if the user clicks cancel, and then exiting the sub if they did?

View 1 RepliesI'm working on a personal project and so far everything is going perfect. Almost. I have a problem with getting music file info based off of its file path. I.e. "
C:UsersUSERetc." The only things I would need from y'all would be how to get the song's Artist(s) and Name (maybe there's something similar to 'AxWindowsMediaPlayer.currentMedia.getitemInfo("Information")' without actually having to play the song?
After I get this information, I would like to know how to add it to a ListBox as this: "[Artist] - [Song Name]", but I can do the text part if I know the getting-the-information part and adding-the-info-to-listbox part.
I have a utility that checks various file info (size, date, location, etc) against a manifest to see that it all matches. Would anyone know if there's a way to get the last write date of a file in a svn repository, using VB.NET. The equivalent of using FileInfo.LastWriteDate.

View 5 RepliesI have to generate an XML file from several database tables. I could use the WriteXml method of the DataSet to do it, but the database tables are really huge and I can't add all those tables in the DataSet at the same time or it may cause a problem because of the big amount of memory used. Then I decided to use the DataTable's WriteXml method and save table after table, but the the generated file only stores the information of the last DataTable.WriteXml's call. How can I preserve the previous XML data when adding all that information?
