View 2 RepliesQuestion: How do I programmatically determine which provider to use (Microsoft.Jet.OLEDB.4.0 vs Microsoft.ACE.OLEDB.12.0) when my app runs as a 32-bit process on a machine with Office x64 installed?
I'm developing a VB.net WinForms app in VS 2010 and targeting both x86 and x64.The app processes data from xls, xlsx, mdb and accdb files using System.Data.OleDb:Dim oConn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=...")
The x64 version of the program works as expected. The x86 version works as expected on a system with Office x86.When I run the x86 version on a machine with Office 2010 x64, I get the following exception when trying to open a connection:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.I believe this is because I'm running Office 2010 x64 so the x86 data access components are not installed.I can get it to work for Office 2003 files (*.mdb and *.xls) by changing the provider to Microsoft.Jet.OLEDB.4.0.
How do I figure out which provider to use when running as a 32-bit process on a machine with Office x64 installed?Ideally, I'd like a function:If ProviderIsAvailableFor("Microsoft.ACE.OLEDB.12.0") Then
Else If ProviderIsAvailableFor("Microsoft.JET.OLEDB.4.0") Then

View 1 RepliesI was wondering if anybody had heard of a library, preferably a .NET assembly, but Java will do as wel, that allows you to read the data in a Guitar Pro file (.gp3-gp4-gp5)I have this gigantor of a folder with about 50.000 song files, and would really love to write something that can actually archive all these files, for easier searching. And basic information like the tuning of the instruments in the song would be very useful parameters to retrieve from the file and add to the database.
I have searched the web but have yet to find anything like this, or a file definition for writing my own parser.
I'm creating a simple forms application where users can enter their details and save the information to a .ini file because I needed this for a simple game profile.

View 4 RepliesI am suppose to create a module level array name Product and populate a list box with the contents of a file (ItemInfo.txt) The file contains the Item ID and price of the item. (Line 1 is an item, Line 2 is a price for Line 1, Line 3 is an item, Line 4 is a price for Line 3, and so on.) The problem i'm having is when i populated the list box, I only wanted to populate the list box with the items, not everyline from the file. I guess I wanted to put elements [0], [2], [4], [6], and [8] from the Product array in the list box, but I am putting everything in there. What am I missing?here is my code so far:

View 5 RepliesI have an XML file (see attached) that has numerous different sections/categories.What I'm looking for is advice on how to pick out the different levels/categories and display them one after the other, with the click of a button obviously.

View 5 RepliesI am making a program that stores information for my applications. There are 4 main things I need in the XML file, the login information (User name and password), Application names and keys, and the owner of the application (who bought it). The program allows the user to enter as many applications and owners as they want and once login information is correct it loads the data. Then on exit all the data saves to a XML file.My XML file looks like this[code]....
Once I read all that the only thing I get is one application and no owners. How do I make it read all of the Apps then stop at the end of the Application Element?
seeing as '.dat' files contain only what you want them to and there is no preset encryption for them etc could I write data to one by using this simple process:
1) Change file extension to '.txt'
2) Decrypt
3) Write
4) Encrypt
5) Change file extension to '.dat'
and pretty much the same for reading it. or am I thinking to simply?
I thought of the above way as i know how to write to text files already, but is this the best way to do it? or is there a better way?
EDIT: Nevermind you just write to it like a text file and encrypt/decrypt it. request lock/delete from mod.
Im making a "offline viewer" which uses saved webpages.I'm using a web browser and a tree-viewer. Currently when you click a link for a file/ installer (for example if you click on the "The Gimp" installer link) you have to right click, and then "save target as..." and then save it (so you would then two copys of the same file) AND then open it.Is there way i could have the file open when the link click? (Again, for example, the running of The Gimp installer apon clicked, or the opening of the video file when clicked)
