Hello
I bought Mydirect 4.30. I created a website I copied the folder bin dll CoreLab.Data.dll CoreLab.MySql.dll CoreLab.MySql.Web.dll I published the site but the server I see this error:

Unable to find the requested .Net Framework Data Provider. It may not be installed.

Check your web.config for referencing correct assemblies in the bin folder.
Have you ever had MyDirect .NET of other version installed on your developer machine? Probably the web site was earlier compiled with other assemblies.

Yes, I had the version Mydirect 4.20 TRIAL. I tried to connect to the database via code is working. When I use mysqldatasource while working locally on the server, I see the error.

Let's reconfigure some references:
- delete all references to CoreLab.* libraries from your current ASP.NET project
- add new references to CoreLab.MySql and CoreLab.Data
- rebuild the project
- deploy the web site

I tried but it is the same.
If I use the code works on the local and server

Code: Select all

Dim cn As New CoreLab.MySql.MySqlConnection("Database=vdlweb;Data Source=localhost;User Id=root;Password=123456;")
Dim cm As New CoreLab.MySql.MySqlDataAdapter("SELECT * FROM audio limit 10", cn)
cm.Fill(ds)
GridView1.DataSource = ds.Tables(0)
GridView1.DataBind()
cn.Close()

If I use the configuration wizard(MySqlDataSource),
I work locally but not on the server. Why?

Could you make minimal installation of MyDirect .NET on the server?
If yes, uninstall any prior versions of the product and make Minimal installation of the new one.

I work locally but not on the server. Why?

Code: Select all

Dim cn As New CoreLab.MySql.MySqlConnection("Database=vdlweb;Data Source=localhost;User Id=root;Password=123456;")

It's not matter where the database is. You can work locally as well as remotely.
From your connection string I can see that you use localhost. Try changing the connection string.
Be aware of the server settings, which should allow remote connection to the database.

The connection string is right. In all the pages of the site using the same string is working. When I use datasource goes wrong. Unfortunately, the server will not install Mydirect me and I do not soche

You need to register MyDirect .NET provider in your web.config.
Here is an example:

Code: Select all


...
 
...

You can get the needed block of code from your machine.config (on the developer side).

I copied the code does not work but nothing more.

This is my web config.

We tested your web.config and it worked fine with a demo web site.
Try inserting command in your web.config. See the code:

Code: Select all

Make sure that the version of the dll specified in the example corresponds to the version of the product installed on your (developer) machine.
