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 "*".

[PlausiblyDamp]

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?

 

:confused:

That's probably the same as if you'd delete it with the explorer.

 

Some other process has opened the file so you can't delete it.

Is the file in use ? :D 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 can't seem to get my Adobe objects to release a file so I can delete it when I'm 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?
