Deleting Files

[lothos12345]

Is there a quick way I can delete all the files in a folder using VB.NET. Any help is greatly apprieciated. Also using an inputbox is there a way I can make the text typed appear to be as "*".

for the first one something like

dim files() as string = System.io.directory.GetFiles("c:\")    change as appropriate

dim file as string
for each file in files
system.io.file.delete(file)
next

for the second IIRC textboxes have a password character - just set that to * and it should work

In use?

But why do I get a "file in use" error when I try to delete files?

Thats probably the same as if youd delete it with the explorer.

Some other process has opened the file so you cant delete it.

Is the file in use ? Are these files you are creating within your application? If so are you closing all the streams / streamreaders down after you have finished with them - if not these will keep the files open.
If they are not files used by your app then what files are they - another app could have them locked.

I am doing both. I process an Acrobat doc and close the doc AND exit the Acrobat app. I also create a log file that I Flush and Close. But when I call file.delete on either file, I get the error.

???

Well! I got my text file to close, now if I can just get the Adobe file to close...

I cant seem to get my Adobe objects to release a file so I can delete it when Im done with it.
I am using VB.NET:
we need delete (temporary) PDF...
close all objects that reference PDF
On Error Resume Next
If Not oAcroDoc Is Nothing Then
oAcroDoc.Close()
endif
oAcroDoc = Nothing
System.Runtime.InteropServices.Marshal.ReleaseComObject(oAcroDoc)
If Not oAcroAVDoc Is Nothing Then
oAcroAVDoc.Close(True)
endif
oAcroAVDoc = Nothing
System.Runtime.InteropServices.Marshal.ReleaseComObject(oAcroAVDoc)
If Not oAcroExch Is Nothing Then
oAcroExch.CloseAllDocs()
endif
oAcroExch.Exit()
oAcroExch = Nothing
System.Runtime.InteropServices.Marshal.ReleaseComObject(oAcroExch)
System.GC.Collect()
delete the file
File.Delete(sNewFileName)

Errors out with "File in use by another process..."

Any suggestions?
