I've built a simple library to import data from XLS/XLSX files. The code runs perfectly in my WinForms app but occasionally throws exceptions when I run it from ASP.Net. The "occasional" part seems to based on file size. My test file is about 16,000 rows and 18 columns totaling about 4MB as an XLSX file. If I drop rows (down to about 12,000) it works or if I drop columns (down to about 12) it works or certain combinations of these (14,000x14, etc) it works. This leads me to believe that I'm possibly running into a memory constraint somewhere. Below is the distilled code that's not working:
Dim dsn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=""c: est.xlsx"";Extended Properties=Excel 12.0"
Using Con As New System.Data.OleDb.OleDbConnection(dsn)
Con.Open()'Exception thrown here
Con.Close()
End Using
The exception that I'm getting is:External table is not in the expected format Searches for this all talk about getting the DSN correct and since it works on the desktop I know I've got that right.My test machine is a Windows 7 64-bit with the Microsoft Access Database Engine 2010 Redistributable - 32 bit installed. (My machine has Office 2010 32 bit installed which is why I have the 32-bit ADE installed, it won't let you install 64-bit.) I've set my IIS app pool to allow 32-bit applications which I needed to get ADE to work in the first place. I'm running the v4 Framework and as far as I know my IIS settings are pretty much standard.Like I said, the code works every time when I run it through a WinForms app but occasionally fails through ASP.net on the same machine.
I created a database program when I used Windows XP and now I'm using Vista x64 When I try to run my program I get error message "Microsoft.ACE.OLEDB.12.0-providers not registerd on your computer. I have looked for solutions everywhere but the only thing I found was for Visual Studio.
View 12 RepliesI am using OLEDB to import data from a CSV file into my database. The code works great as long as the file has a .CSV extension. My problem is that it fails if the file has no extension which is the actual case in my files.

View 6 RepliesI am having a problem with my application. When it is run, the error displays The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine. I tried changing Platform to X86 CPU but it could not be changed, the only available option is Any CPU.
View 2 RepliesI have created an application in VB.Net 2010 and am using an Access 2010 db. Connecting to this DB I use the Provider= Microsoft.ACE.OLEDB.12.0 and it works fine on my machine. This was a recent update from using Jet as that provider was having issues on client Win64 computers that had Access 2007 or 2010 installed.Basically my issue is that I get the error that Microsoft.ACE.OLEDB.12.0 is not installed when I try to run the application on the client.
The problem however, is that I do not want ask the users to install Data Access Objects in addition to .Net 4.0. I want a simple install that they can run and upgrade to .net 4.0 if they need to. The above thread states a solution as "You can also consider to use ADO.NET object in System.Data.OleDb namespace to connect to the Access database instead of the Provider. In my opinion, this is the best choice since the ADO.NET provides you the powerful data access objects." This sounds like a great option, however I cannot find any way to install the ACE dll and get it to work on the client.what do I need to include in the client installer to get my application to run on systems without Access installed? Do I just include the ACEODB.dll or is there something else that needs to be done?
Looking into the problem I've seen that it's often due to running 64 bit VB but Access is 32 bit. However, I do not have Access on this machine, is there a way around this problem? I need to use Access for school, so changing that isn't an option.
View 6 RepliesI have an application in vb.net and ms access as backend. The problem is when application wants to connect with the database it will show an error like "The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.". My connectionstring is

How can i solve this issue. My OS is windows 7 (64 bit).
Dear Microsoft: You should DEEPLY CONSIDER releasing a 64 Bit version of Microsoft.Jet.OLEDB.4.0.why x86 = 32 bit and x64 = 64 bit?
I use Jet.OLEDB.4.0 ALL THE TIME! I actually just finished a program yesterday that used the exact same line of code, and it works fine today but the new program does not.

View 6 RepliesI need to export data into an Access database. My code works, but it works with the assumption the client machine has the Microsoft.Jet.OLEDB.4.0 as a valid provider.
I want to test to see if this is true or not, in code. My problem is that I don't have the location of an existing access database and I don't want to create a new .mdb that I'd use to verify the connection and then delete it.
My first project was a small windows form application that I'm hoping to put on the office server and have it accessible to more than one person at a time. I wrote the code in Visual Studio, and put the exe file and access database on the office server. When another computer (that doesn't have visual studio installed) opens the file this error comes up: The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine. I realize I may need a quick download on these other computers to be able to read the VB program?
