Solution 1

It doesn't matter that it's a static method - do it the same way you normally would.

i normally writing code and work well but when i create procedure and call it ,,,give me error that this is static function

You may be access any instance variable of the class jobs from the static method?

shms_rony 1-Apr-11 8:02am

sorry can you write code

Albin Abel 1-Apr-11 8:13am

Sorry I can't. I didn't thought of learn coding from your question.

shms_rony 1-Apr-11 8:15am

this is the error when i call procedure to this method

"An object reference is required for the non-static field, method, or property 'myScheduler.Jobs.con"

Albin Abel 1-Apr-11 8:28am

Looks like the connection object is not instantiated inside your static method. The error is self explainable isn't it?.

I guess you meant "self explanatory" :)

Albin Abel 1-Apr-11 8:35am

oh yes. Thanks

Yes, I can write code, but you, apparently, cannot.

Solution 3

The problem with your code is that you are trying to access a non static field or method or property from your static method. This cannot be done because static methods can be called without instantiating an object of that type, so relying on instance fields, methods or properties is not possible.

If there is no reason for making your method static then I'd advise you to remove that keyword from the method definition. If you can't do that for some reason, you can only use local variables and static fields, methods and properties of your class from within your static method DailyJob.

when i remove static word ..another error

"TimerCallback callbackDaily = new TimerCallback(Jobs.DailyJob);"

Albin Abel 1-Apr-11 8:42am

Ofcourse you are passing a static method as argument (jobs.Dailyjob) which doesn't exists now. The answer already given. Static method only access static members or localized instance members. So move your objects accordingly.

Albin Abel 1-Apr-11 8:38am

Agreed. It seems like his method access instance members. OP may need a instance method than a static method. My 5
