.net - Data provider to support SqlServer and Oracle -

-

I am working on an ASP .NET application which uses the .NET 3.5 framework. I have to implement a provider that works well with both Oracle and SQL Server, and hardly MySql, because we are going to sell products to customers who have one of these databases Should also be able to communicate with the person what is the best way to implement this data source? Besides, can someone provide me some sample examples? Thank you.

Why do you want to write a dataproder for all the databases? Just write the configuration that helps in configuring the database for the database specified by selecting the database type and other database properties, and change the app.config file by typing the specified datesteputer into your configurator

< Strong> edit

Here are the ways to use DbProviderFactory, you can find more samples in the web, just use this class instead of the specified squares,

CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there.
