Hi
i create a windows application using vb.net 2008 and i use local data base file with (sdf) extension
then i create an installer file(exe) after that i install the installer on another machine

it install successfully ,but when i run the application i receive that access is denied to the sdf file

i solve the problem by going manually to the sdf file --> right click-->properties-->permission
and i give full control
and it work
now how i can solve this problem because i don't want to go to each machine around the world and do that

Sounds like you are storing the database in a restricted location (My Programs?). If you put it in the AppData folder, which does not have the same permission problems. Plus the file path can be easily retrieved using My.Computer.FileSystem.SpecialDirectories.CurrentUserApplicationData

In the File System Editor, add the "User's Application Data Folder" special folder, then add your database to it.

As a rule, only put files that you do not need to manipulate in the Programs folder. Anything else can go in the AppData folder.

Try inserting this block of code in your applications "AssemblyInfo.vb"

Imports System.Security.Permissions

<Assembly: FileIOPermission(SecurityAction.RequestMinimum, Read:="Path of your sdf file")>

Open in new window

If your database is in the same location of your exe, then just put the name of your file. The default is the same location of your program.
see below...

'The database is similar to the path of the exe file.

Imports System.Security.Permissions  

<Assembly: FileIOPermission(SecurityAction.RequestMinimum, Read:="Database1.SDF")>



or



'The database is located in a folder inside within in the exe file location.

Imports System.Security.Permissions  

<Assembly: FileIOPermission(SecurityAction.RequestMinimum, Read:="\Database\Database1.sdf")>

Open in new window

To add special folders such as Users Application Data folder you have to RMB on the file system node and select the desired special folder

To make sure SQL CE gets installed before your application you have to set the pre-requisites by RMB on the Setup Project and selecting 'Properties' then click the Prerequisites and browse down to the correct version of SQL CE.

Pre-requisites are only enforced by the Setup.exe so if you run the msi directly they will not be checked or installed.  The best way to ensure the setup.exe is run by the end user is to utilize one of the self-installers to unzip the files and automatically execute the setup.exe.  I use winzip for that.

BTW one of the reasons the file cannot be edited on some computers may be due to changes in how windows vista and 7 protect certain directories suchas Program Files.  No application is allowed to edit files in these directories without RMB>Run as Administrator.  This is why it is necessary to put files that the application needs to edit in an accessible location like User's Application Data Folder.  In XP this was not necessary.

Yes it does.

In vb it is under My.Computer.FileSystem.SpecialDirectories

This will give you the <OS User or all User folder>Application Data\Company\Product\Version&GUID folder you can use IO.Path.GetDirectory(SpecialFldr) once to get the Product folder and twice to get the company folder.
