Nowhere in your code is there any provisions for handling the inevitable "access denied" error. Your code probably bombed in the root of your C: drive on a folder called "System Volume Information". You have to put some of this code in Try/Catch blocks to handle this eventuallity and deal with it as you must.

i didn't see any output from your search, just calling di.listfiles(type) but not adding it to anywhere!
and you are searching only C drive, what if your computer have morethan one drive.
try this
initialise your search like this
dim drv as driveinfo<br />
for each drv in my.computer.filesystem.drives()<br />
if drv.isready then<br />
searchfiles(drv.rootdirectory,type)<br />
end if<br />
next
and create a searchfiles method with path and filetype as parameters
private sub searchfiles(byval path as directoryinfo,byval filetype as string)<br />
try<br />
'this will handle the error access denied<br />
'list files<br />
dim fi as fileinfo<br />
for each fi in di.getfiles(filetype)<br />
Application.DoEvents()<br />
'do something with the file here<br />
next<br />
'now go through the directories and get files from subdirectories<br />
dim sdi as directoryinfo<br />
for each sdi in di.getDirectories()<br />
Application.DoEvents()<br />
searchfiles(sdi,filetype)<br />
next <br />
catch exception as ex<br />
end catch<br />
end sub
this will get you through all the directories in a computer.
hope this works for you

Check out the NotifyIcon.
Trinity: Neo... nobody has ever done this before.

1) place a shortcut to your app in the start menu/programs/startup folder
2) do research on System.Windows.Forms.NotifyIcon
in the forms' closing event
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
e.cancel=true
me.hide
turn on the notifyicon object
End Sub

Hi Rupesh
Thanks, that does work

Thanks for your help though

Does anyone know how to fix this, and if there is a better way?
Thanks

I have created one application in VB.Net.
I want to create one shortcut for it
like Window key+E (for Explorer).
How can i do that?
|
|
|
|

I'll need some clarification.
Are you looking for a shortcut like from you own desktop or are you looking for how to create a shortcut to your application from within a distribution set? So as to automatically create a shortcut on a users PC desktop when installing your app.

You will need to use Win32 API.
here are functions you can use...
<br />
[DllImport("USER32.dll")]<br />
public static extern bool RegisterHotKey(IntPtr hWnd,<br />
int id, int fsModifiers, int vlc);<br />
<br />
[DllImport("USER32.dll")]<br />
public static extern bool UnregisterHotKey(IntPtr hWnd, int id);<br />
"If our Mind can, the Program can !!"

|

Are you going to check whether the user is using that shortcut for something else first? Hijacking users' control over their own machines is not a way to create good will towards your app.

Hi,
Currently I am designing a tool in VB.Net for automation of a datawarehousing tool called DataStage. I have to run this tool through command prompt in VB.Net. The command is
dsjobs –server xx.xxx.xx.xx –user abcd –password wxyz –run
[Project] [Job] [List of parameters]
Application path is the location where datastage client is installed in the local machine.
Other attributes like:
-lparam: Give the list of parameters for a particular job
-ljobs: List all the jobs in a particular project
-lprojects: List all the projects available in the server
-run: To run a job
-stop: To stop a job etc….
Now can anyone help me how to put these in VB.Net and how to fetch the results of these commands. Because based on the results of these commands I have to create dynamic text boxes.
It looks complicated, but can anyone who knows this help me out ?
Thanks in advance.

Process.Start is basically shellexecute, you can pass your parameters through there.
