Hello!

I found on a website that i need the MySQL OleDB Provider to connect to a MySQL database from C#. I installed the provider but i don't know how to use it. Do i have to use OleDbConnection or OdbcConnection? Or is there an easier way?

Thank you

Hi,

You can use the Graphics.Transform property of your graphics object to set a Matrix that takes care of the rotation (use the Matrix.Rotate method) of your text in case your two points are at different lattitudes. After that, just use Graphics.DrawString to render your text, be sure to take into account that the matrix transformation influences your grid positions too.

Standards are great! Everybody should have one!

VS question about the auto generated InitializeComponent() method

akkram26-Nov-07 20:51

Hi. I have a question regarding the auto-generated InitializeComponent() code when using visual studio. For example, if I have a form and a user control. Now, when I drag the user-control onto the form VS automatically instanciates the user-control inside the InitializeComponent() method. But say I have a property in the user-control I want to set through it's constructor, ie. passing some parameter when istansiating the user-control. How can I do this without editing the InitializeComponent() in the code-editor?

To use your UserControl within the VS Designer it has to have a default constructor.

I see two solutions to your problem:

1) let everything the way it is now and add a property set what you have to set.
2) Add your UserControl dynamically (with the constructor with your parameters) in the Load event of your Form.

If you want designer support then I'd suggest you use solution 1. The property value can be set either in the designer (if it is a constant value) or somewhere in the code.

Happy coding
