Can't Delete My Release File?
Mar 31, 2009I made a .exe file of my project (in vb2008 express ed.) and it was all working and then I copied the release file out of my project and an error came up (something about UNC share) and i realized the path was wrong, so when I tried to delete the Release file (currently on my desktop) a pop up message says you need to be administrator to delete this file so I press continue (as I am the administrator) and another message comes up saying "You need permission to do this" "Try Again?", when I click "Try Again" the same message comes up. I know this isn't directly involved with VB, which leads me to my second issue:
How can I create a file that is external from VB yet it still works? In my code there is a path that connects it to SQL is it perhaps something to do with that?
How To Get Webbrowser To Release File
Dec 1, 2009I am writing my first vb.net program that displays a .pdf file in a webbrowser control. I have setup a routine that moves the file to a different folder. The problem is I get the following error: "The process cannot access the file because it is being used by another process." Is there a way to release the file from the webbrowser so that I can move the file.

View 5 RepliesTiffBitmapDecoder Release File?
Mar 9, 2009I have a system that scans in images to multi page tiff files and allows the user to preview before finalising. When the user previews,they click on the page number which should then use the TiffBitmapDecoder to read that particular frame in from the Tiff file and display the BitmapSource in an Image control...this works just fine. The problem comes in when they scan another page which is then inserted into the tiff file. The tiff file is returning that it cannot be accessed as another process is using it. How do I get the TiffBitmapDecoder to release the Tiff file?

ASP.NET Wait For File Upload/release?
Jul 21, 2010I've got ASP.NET intranet application written in VB. It gets a file from the user, and then depending on a few different cases it may create a few copies of the file as well as move the original.
Unfortunately I've come across a case where I get this error:
Exception Details: System.IO.IOException: The process cannot access the file
'\somedirD09_03_5_180_0.000-6.788.png' because it is being used by another process.
Which is thrown by My.Computer.FileSystem.CopyFile. And that's fine that it's being used by another process - it may still be saving/downloading from the user or trying to copy while another thread(?) is copying, I don't really care about that, what I want to know:
Is there any way that I can tell VB to wait to copy (also move) the file until the file is no longer in use?
Combine All Release Files Into ONE .exe File?
Jul 23, 2011How can I combine all of the output Released files into just a single .exe file? Like for example I have these file extensions: .exe, .pdb, .vshost, vshost.exe, vshost.exe.manifest, and then 2 xml files that have to do with my program.
So once again I am trying to get all of these files into possibly one file. Do you know how when you go into your Windows Program Files folder, there are none of these files. I am basically trying to do the same thing.

.net - Release A File Lock On A COM DLL That Has Been Instantiated Via `CreateObject`?
Dec 21, 2011I have a .Net 4 WinForms app that generates a DLL, calls CreateObject on the generated DLL then calls one of several methods that the DLL contains. The DLL is eventually used by a separate app. This WinForms app is just to generate and test the DLL hence why it can generate the DLL multiple times.The problem lies in the fact that calling CreateObject on the DLL locks the file to the process. The next time the DLL is generated it can't overwrite the previous DLL file on disk without closing the app completely and starting it again.
I've tried Marshal.ReleaseComObject, executing the CreateObject in a separate AppDomain, even setting the variable holding the COM object to a different COM object via CreateObject, manually calling GC.Collect() and a whole host of other things but none result in unlocking the file.The code flow is basically (simplified and generic names, etc.):
...
' Compile and generate DLL that is COM enabled and works fine
...
Dim foo As Object = CreateObject("Bar.Foo")
[code]....
is there a way to release a file lock on a COM DLL that has been instantiated via CreateObject without killing the process?
Note: this is a continuation of this original issue. I now have the DLL registering without locking the file but now the issue is with the CreateObject call not the DLL registration.
1 IDE Won't Release File Locks On Referenced DLLs
Mar 20, 2009I develop an application through two multi project solutions.There is one solution for the data layer stuff and another one for the front end stuff.All the dlls are referenced in a startup project and have copy local = true. So the build output from the GUI solution and the dlls referenced from the data layer solution should be copied to this startup project's bin folder. This seemed to work without issue for some time, but after changing source control, after a rebuild of the data layer solution, I clean the GUI solution and get the following output: [code] I have researched this problem and it seems microsoft are aware of a problem, logged under MSB3061... but no solutions have been posted by MS. Several users have suggested stopping the indexing service from indexing bin and obj folders (I've done this). I've also ensured that none of the bin/obj folders are under source control. I downloaded FileMon from sysinternals and it says that devenv (GUI) has the file locks.

View 2 RepliesRelease MS Access LDB Lock File After Created It?
Feb 17, 2012I have difficulty in removing the LDB generated by the "CREATE" method of ADOX in the following code segment.Aims: Create (on the fly) a new access database and then export data (says Arena modules) to that newly created database.
Expected: The newly created access database should be able to be used by some external operations, say Access.exe, after the end of the subroutine and without exiting the current VB program.
1) I tested that the "Arena code" do nothing about the create/release of the ldb file.
2) I tested the "Exclusive Mode" in connection string, but the access file is still locked by the vb program.
3) I tested under both inside the VB environment, and directly invoke the generated from Explorer, and same results.
4) Other database formats is not the options to me. (due to Arena export limit)
5) It is not a web app.
Code:
Sub Method1()
Dim logs As New System.Collections.Generic.List(Of String)
Dim arenaApp As Arena.Application = Nothing
Try

View 3 RepliesAXWindowsMediaPlayer Taking A Long Time To Release File On Close
Aug 29, 2011I am writing an application for managing mp3 files. I use AXWindowsMediaPlayer1 for playing files and UltraID3 for reading and writing ID3 tags. Every time the user selects to switch to next song, the ID3 tags of the current file need to be updated. My problem is with Media Player taking a long time to release a file for access after doing a "close". Currently I need to add a 6 seconds delay between the "Close" method of the media player and the ID3 tag "Write", otherwise I get the error saying that the file is currently in use. Anything less than 6 seconds does not work...
I attached a short version of my application which focuses on the issue.

Jun 18, 2010What is the 'proper way' of giving my application to people?
Ideally I just want to zip up the minimal amount of files and for people to put this in a folder of their choice and just run it.
I've noticed from playing with a "Publish" I end up with a "setup.exe" and also a "Application Files" folder.
Within that folder are the necessary files (a DLL and a .EXE) to run my application. Can I just supply those two files out to people?
Oracle 10g To 11g Release 2
Apr 21, 2010Currently we are using the Microsoft data access library Writen with a Oracle data provider for the framework 1.1. My customer has mandated that we upgrade from Oracle 10G to 11G release 2. 11G requires the .net framework 2.0 Is there a way to use the new Oracle data provider 11g release 2 with the older frame work. I have looked at/attempted changing the policy for oracle in the Windows assembly but my understanding is because its a third party DLL, I cannot.
View 4 RepliesRelease All The Memory?
Oct 1, 2010in main form, when a button is clicked, it opens a new form which has a webbrowser. users can use it to browser some sites. if the user closed this form, it goes back to the main form. and they can click button to open the browser form again.
I noticed that one thing. if the browser form is opened, it uses much memory (which is normal because of the site it browses). however, after the browser form is closed, the memory is not released.
In the browser form, when it is closing, the webbrowser is disposed and dereferenced. and no other part uses much memory in the form. GC is called too. what else should I do to release all memory the browser form uses?
now, it is like once the browser form is opened once, the memory usage never goes down even the form is closed.

.net - Release DC Before Or After Graphics.Dispose?

Private Declare Function ReleaseDC Lib "user32.dll" (ByVal hwnd As IntPtr, ByVal hdc As IntPtr) As Integer

Why did they do it this way?Should the DC be released before or after Graphics.Dispose?It is possible that the wrong order can cause resource leaks or memory corruption?
