How can I tell my program to read the folders that are different on peoples computers like mine for example.

C:\Documents and Settings\Code Crapper\Cookies

Now as you can see your computer has not got that, your computer (if its XP) would have.

Drive letter:\Documents and Settings\Your Name\Cookies

So my question is, how do I get it to work on anybodys computer? do I have to do something like this?

%systemroot%\DOCU~\%USER%\Cookies ????

Unsure | :~

Are you trying to access the "Documents and Settings" folder, or the current user's folder?

I need to get through the bit that says Code Crapper, the user name because otherwise the program wont work on any other computer with a different user name.

So far I have "C:\DOCUME~1\username (dont work)"

The 'DOCUME~1' bit works but I just need the username bit, I tried 'USER~1'and 'USERNA~1' but no luck.

All I need to know is the Username one and then I can do things like.

C:\DOCUME~1\Username?\Cookies

I can do anything else which does not require a user name too like

C:\DOCUME~1\All Users\LOCALS~1\

Ok, for the current user, just use the path variable %HOMEPATH%, which specifies "C:\Documents and Settings\Current User".

If that doesn't work, then you could try accessing the registry key:

HKEY_Current_User\Volatile Environment\HOMEPATH

The way to get the path to the root of the users profile is to use the Environment.GetEnvironmentVariable method:

Dim userPath As String = Environment.GetEnvironmentVariable("USERPROFILE")

The proper way to get the path to the current users Cookies folder is different:

Dim cookiePath As String = Environment.GetFolderPath(Environment.SpecialFolder.Cookies)

Track changes in a control's value property without . . .

Hello,
I have a tabbed form that contains hundreds of controls. Way to many to program a _valueChanged event
for every single one of them. Is there a form or tab level event that keeps track of its child controls and whether or not their value property has changed ?
All i want to do is flip a boolean if a control's (any control) value has changed.
If you have a simple way to do this I would be obliged if you would share it.

Thank you very much,
Shawn

I don't think you can. I've tried doing the same with a _MouseOver event, and ended up changing each one anyway.

Just use a For Each statement, like this:

For Each foundFile As String In My.Computer.FileSystem.GetFiles("C:\", FileIO.SearchOption.SearchTopLevelOnly)
ListBox.Items.Add(foundFile)
Next

Then why rush people?

You didn't change "ListBox" to the name of your list box. I.e. ListBox1 or FileList.

Just use My.Computer.Audio.Play("C:\File.wav", AudioPlayMode.BackgroundLoop).

You can only play Wave files though.

You want to actually write a web browser ? That is, not use the web browser control ?

OK, will you support ActiveX controls, javascript, etc ? How many years do you have to do this, assuming you'll be alone ?

Drawing.Image.FromFile "out of memory"

I have a multi-page tiff that's over 1meg. I get an 'out of memory' error trying to open it from the method 'fromfile' I have tried 'fromstream' and can't get past 'an invalid parameter used' when everything that I'm using is correct. My ultimate goal is to get a count of how many pages(images) are embedded in the image file so that I can tell how many images a java applet can expect in the file. This code works but craps out of certain files and I don't know why... Any help would be appreciated...

Dim oFile As New FileStream(sTiffFilePath, FileMode.Open, FileAccess.Read)
oImage = System.Drawing.Image.FromStream(oFile, True, True)

'exception -- invalid parameter used

or

oImage = Drawing.Image.FromFile(sTiffFilePath)

'exception -- out of memory

Dim oGuid As Guid = (oImage.FrameDimensionsList(0))
Dim oDimension As System.Drawing.Imaging.FrameDimension = New System.Drawing.Imaging.FrameDimension(oGuid)

iGetPageCount = oImage.GetFrameCount(oDimension)

oDimension = Nothing
oGuid = Nothing
oImage.Dispose()
oImage = Nothing

You'll have to check the compression used in the TIFF. GDI+ doesn't support JPEG compressed TIFF's.
