Access Database Files In Vista?
Mar 19, 2009
I am writting an application that stores data in an Access database. I can't put the files in the Program Files directory since standard users can't write to that folder. I can't use a 'user' folder since multiple users will need to access the same file. In addition to accessing the file, users on occassion will copy new versions of the file into the folder, overwritting the old file.Where should I put this file? I am thinking the ProgramData folder, but when I create that folder during the install, it is also read-only for a standard user.I'm lost as to where I should put a file that can be accessed by multiple users, that is read/write, and I can install the folder into the location. I don't think I have a programmatic way of installing a file into the Public users folder.

I posted this as a bug on MS Connect and am wondering if anybody else can verify the problem: I been beating my head against the wall for about 3 days and I don't think it is my problem.
Desktop computer - Vista 64 bit
Portable Computer - Vista 32 bit
vb.net 2010 express on both of them
I can not establish a connection to an Access db (either .mdb OR .accdb) on the 64 bit computer. When I try I keep getting a message that says "Format at the initialization string does not conform to specification starting at index 0." (this was typed not copied). (There are screen shots over on Connect).
I can establish a connection to a "Microsoft SQL Server Compact Edition" (.sdf) database on the 64 bit computer.I can estabish a connection to all 3 types on the 32 bit computer (.sdf, .mdb, .accdb).The 'funny' thing is that if I establish the connection on the 32 bit and copy the program directory over to the 64 bit, the prorgam loads and seems to run fine. But the %$# _(%* Wizard will not run on the 64 bit machine. Runs fine on the 32 bit but not on the 64 bit. Of course I make sure that the db's are in the location where the program expects them to be when I run the program on the 64 bit machine.
One final thing, when I am in the progam created on the 32 bit and running on the 64 bit and I try Data->Add New Data Source->Database->Dataset only two of the three connections show up while all 3 show up on the 32 bit machine. Also the connection string is incorrect for the non-sdf connection. It should include

I have a VB6 application which has been running succesfully for years under XP, however under Vista data loss has been observed.It appears that if the app is run 'as administrator' then it connects to the correct database file, however if the app. is not run as administrator then vista creates a copy of the database (no idea where) - hence I end up with 2 versions of the database.
In fact I can delete the database file entirely and the app. still works fine because vista is using it's own copy - the problem is how do I back up this 'vista copy' when I can't find it (search doesn't find it).

I am trying to import a bunch of excel 2003 files all with A:H columns and they are under the same headings etc. into a table in access 2003 database. This is a module in access im making. Im using a file search to look for every file that begins with Format (which they all do ) to get at all the files in the folder path. is there a more efficient way to do this? somehow select all files in a folder? and import each to the same table in access? The DoCmd.TransferSpreadsheet seeems to take each file path individually so I'm not sure how to get each file name in the folder to import it.
I have this at the moment:
Sub Import()
Dim db As Database
Set db = CurrentDb

I am working on a very simple program for someone and because it's been so long since i've programmed, I'm looking for an answer as to the best way to do the following.
My program consists of tracking incident reports and each report needs to have the data entered as well as the "paper form" linked to it that shows the members signature. I have everything completed on the program but how to get my file to link with the incident. I am using Access for my database and have been looking everywhere online on how to attachment documents within Access using the Attachment Datatype. So my question is.....
Should i find a way to import the file to Access, and if so, how do i do this, or should i just send the file path to Access as a text field, and then hyperlink the file when it is displayed on the report? I've never done anything like this and was just looking for some pointers.

I'm having some problems with people saving text files using my program, but only people using Vista. Since I don't use Vista myself, I'm not sure what this is but it's not a problem on any machine running XP.
Note that my file saves just using the standard Savedialog box and Filestream/Writeline commands.
From what my customers are telling me, the save dialog comes up fine and there is no error as the file appears to save, but when they look for the completed text file, there's nothing there.

I have encountered a small problem with my application due to the updater I built in.Basically the way the updater works is:1) Check for updates2) Download the new .exe file as "tmpMyApp.exe"3) Download "Rename.exe"4) Launch "Rename.exe" and exit application.5) "Rename.exe" then deletes the old application and renames the tmp one with the origional name "MyApp.exe"6) Launches "MyApp.exe"This all works completely fine for me, except when the program is installed in "C:Program FilesTinyGrab" this causes my app

I have a user of one of my programs reporting that they get an "access to the path...is denied" error during this section of [code]He's using Windows 7 x64 with UAC turned on. The location of "FilePath" is a subdirectory inside Program Files (x86) in this case.I tried to reproduce the error on my Windows 7 x64 system by enabling UAC (I usually have it off) but the program worked fine. However, in my case, "FilePath" is not in a protected system folder like Program Files (where write permissions are not given to normal users without admin elevation).So I tried to recreate this situation on one of my Vista x86 Virtual PCs where the "FilePath" would be inside Program Files. However, my program again worked fine. It had no problems writing to the Program Files folder with a normal user account, UAC turned on and no elevated permissions required.
Thus, I am confused. Why does it work for me and not for him? I want to try an x64 virtual machine but I can't with the software I have (Virtual PC doesn't support x64 guest OSs, VirtualBox won't run the software that my program interacts with). So maybe you guys can help me instead. Are the write permissions for the Program Files (x86) folder different between x86 and x64, or maybe even Vista and 7?

We have code in our former VB6 application, that ported fine to VB.NET, that plays a simple AVI file of the typical "flying folders" and "spinning maginfying glass" AVI. Under Windows XP, our application ran fine and everything was good.
Then we had customers start using Vista and Win7 and this stuff crashes. We were using the MS Common Controls (SP4) and then (SP6) - utilizing the Animation player. Now - these dont work and we get nasty errors.
I searched Microsoft and the web to answer the "what now?" question and though there are numerous suggestions, none of them work. We cant use Media Player because we dont want any menu - just the graphic. We dont know why, with the cool tools given in .NET, there is no animation player (seems a huge oversight...) But we need to get "unstuck" on this one, and we need that fast...
So, How does on play a simple AVI file using VB.NET code? What DLL or OCX does Microsoft recommend and is there a place we can find some sample code for it?

Im working on an AutoUpdate class for a small application I've been working on, and with Windows 7 and Vista machines I get a permissions error when trying to replace some of the files in the Application folder. The only way to get it work is to run the application as an administrator. Is there a way I can either attempt to automatically run the app as administrator, or a way of replacing the files that won't be blocked by Vista/7's permission gatekeepers?

It is my hope that there will be two user account types: 1) Standard User and 2) some other user type such as Power User or something else that will distinguish it from Standard User
