USing SHFileOperation To Delete Temp Files In .net?
Sep 14, 2009
I would like to know how to declare this function, I have seen it used and i have the class SHFileOPStruct and all the components of it, i have then declared a function with the components of the class i am using, and when i try and follow examples of how to use the SHFileOperation function i get an error asking me to name SHFileOperation, how would i name it? Is it not an inbuilt function?
What am i actually trying to do? Delete temperary folders that are created during the running of my program. How can i do this using SHFileOperation
here is my code below:
' Declaration for File Recycling (from modFCOM)
Public Structure SHFILEOPSTRUCT
Dim hwnd As Integer
Dim wFunc As Integer 'operation to be done

I'm trying to read a csv file. I'm also try to delete all files in the temp directory on the page load. Everything goes fine the first time, but the second time I get an error saying it couldn't delete the file because it is in use by another process. I'm aware that this process is my vb file, I just can't seem to find what I need to dispose of to get rid of the file lock.
Here is my code
Imports System
Imports System.Web
Imports System.Web.UI.HtmlControls
Imports System.IO
Imports System.Xml

I am trying to create an MDB as a temp file to save some tables and query them. After creating, I can't delete it ... Even before it is actually used. The process cannot access the file because it is being used by another process.
Dim mdbFileName As String = System.IO.Path.GetTempFileName
Dim objClassType As Type = Type.GetTypeFromProgID("ADOX.Catalog")
Dim obj As Object = Activator.CreateInstance(objClassType)
obj.[GetType]().InvokeMember("Create", System.Reflection.BindingFlags.InvokeMethod, Nothing, obj, New Object() {"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & mdbFileName & ";"})
[Code] .....
This MDB (after all operations) is huge (+200 Mb) and needs to be deleted.

I am trying to write a program that deletes temp files from my entire c drive. windows 7 will not allow any file manipulation. access denied . everything works fine in windows xp. what needs to be changed in my code to allow anyone to install this program on their computer and run it without errors like this. I need to change my code to correct this not windows 7, as other people will be installing this on their systems and they can't be setting their c drives. every answer i've found online is either to change c drive to have no security or set the code to demand uac to run as administrator(which doesn't work )

Am trying to copy contents of file temp.fxl to temp.seq. I want them to look exactly them. I don't want to copy the file though. I use the following code
Dim fs As New FileStream("c:\fxlate\output\temp.fxl", FileMode.Open, FileAccess.Read)
Dim s As New StreamReader(fs)
[Code].....
With such simple code, the last line in temp.seq is truncated as attached and the size of the file is smaller than temp.fxl. See attached files. What do I need to do on the above code. Is VB.NET failing to write 1024 characters on one line.

I have pasted below a piece of code where I am displaying a report. I am using Visual Studio 2008 Crystal Report engine. It works all good with the piece of code
Problem: Everytime a report is being run it generates a ('.*tmp', '.*rpt') files typically in a temp folder c:windows emp however we can get rid of the *.tmp files by setting a recycle on the application pool but need a way to get rid of the .rpt files.
Found solution: Call Close() and Dispose() on the report object. The way I am doing is crReportDoc.Close() then crReportDoc.Dispose()Actual Problem: If Dispose() is called the report comes up with the following error 'Object reference not set to an instance of an object'

My.Computer.FileSystem.DeleteFile(foundFile, FileIO.UIOption.AllDialogs,FileIO.RecycleOption.DeletePermanently)NextI would like to adapt this code to delete all the files in a folder of my choosing; for example, all the files in c:msdnimages. But I'm not getting anywhere.Would someone be kind enough to explain how to substitute c:msdnimages for SpecialDirectories.

i want to delete some files but only if they aren't in use. What i did was a try/catch:
Try
My.Computer.FileSystem.DeleteFile(fileInfo.FullName)
Catch ex As Exception
End Try
but it seems that this method is very slow if i try to delete some files over network.
Is there an faster way to delete files? Is it faster to check first if an file is open? If yes, how can i check if an file is open?

I created a program that allows my users to upload files to an FTP server and make folders. I have one problem. they cant delete the files yet. [url] you want to see the Upload page just enter random credentials). I was wondering if someone can help me make another form that displays files and folders and subfolders, maybe a listbox and when a user highlights something and clicks the delete button it will delete it or the rename button.
