View 1 RepliesWe are installing our application on windows 7. The application utlizes a Acces database. The application locates the database by looking in the registry under at HKEY_LOCAL_MACHINE / SOFTWARE / WOW6432NODE / COMPANY NAME / SOFTWARE NAME /STARTUP. When i install the application on windows 7 it places the a database where installshield directs it to and writes the path to the registry. However, somehow local copies of the database are showing up under the user profiles. (Example: c:/users/profilename/AppData/Local/VirtualStore/Program FIles (X86)/Company/SoftwareName/Data). We recently changed it to store the information in c:/ProgramData/Company/software however the same issue occurs and its creating local copies of the database and when the application runs it points to the local copy of the database. What we need is for all users to be pointed to and use the same database in ProgramData, is there something we are missing to accomplish this?

View 12 RepliesI have to write an application in Visual Basic.Net that will open an excel file, run through the contents an export a test file for processing.
The application works great for me (Windows 7) but when transferred to a WinXP PC gives the following error: HResult 0X800A03EC
I can replicate this error by making the Excel Application visible so it seems like it is an issue where it can't access the file because it is open. Error occurrs when trying open the workbook.

How can I open a Visual Basic application that I created in 2002? I downloaded a current version of Visual Basic Express and was able to connect a new project to the .mdb files but I couldn't figure out how to open the other files which I need to actually use the application.
Ideally I'd like to run the .exe file, but it doesn't seem to be compatible with Windows 64-bit. Alternatively I'd be happy recreating it with the various components if I could figure out how to access them.
As the title says, I have a program written in VB.net 2010. When I use the publish feature it creates a manifest and setup file that install the program nicely on another PC, but I think the security settings are somehow wrong because it sits there for ninety seconds upon launch. The program works fine on the computer that built it. There is no CPU usage while it is sitting around.

I am creating a Visual Basic 2008 .net application that will be using the Sync Service for ADO.NET on Windows 7 Ultimate. The back end database is SQL 2008. Below are the basic steps I take when the error occurs
a. Add a Local Database Cache item to my application
b. Use the Configure Data Synchronication wizard for the setup process
c. Click the OK button to accept changes
d. An error message is generated, "The given key was not present in the dictionary".
I have attempted this several times and the error message presists no matter how I vary the options. I have also installed Microsoft Sync Framework 2.0 successfully but the error persists. I also have all the following Dlls referenced in my project:
Microsoft.Synchronization.dll,
Microsoft.Synchronization.Data.dll,
Microsoft.Synchronization.Data.Server.dll,
Microsoft.Synchronization.Data.SqlServer.dll,
Microsoft.Synchronization.Data.SqlServerCe.dll.
I am sure I don't need all of these references but I figured it does not hurt to have them all referenced for now. I have the latest OS service and Visual Studio 2008 service packs.
