Calling non-static methods in dll

Hello,

I have a dll which is developed in C#. I have made a reference to it from Reporting Services under Report Properties.

My problem is, that the methods in this dll are not static. Therefore under the Classes in Report Properties I have written the class-name and the instance-names of the instances that I need to use from this class (as I understand it, this is what you have to do if using non-static methods). In a text-box, I call one of the instances in the class, but I get this error:

[rsInvalidName] 'MyMethod()' is not a valid code class name. Names of objects must be CLS-compliant identifiers.

What exactly have I done wrong here?

Thanks

Hi Peter,

In the code window, you'll need something similar to:

Dim InstanceName As Instance

Then you should be able to set the value of your textbox to: =Code.InstanceName.FunctionName(Params).

Keep in mind that all of these lines are case-sensitive.

If this isn't working, could you post a snippet of what you're doing, so we can take a further look at it?

Hi Jessica. Thanks for your reply :-)

I have a class (let's call it myClass) and a method in that class (let's call it myMethod).

The Class is declared as: public class myClass and the method is declared as: public string myMethod(params).

The resulting dll (let's call it myDLL) is added to the references-tab of Report Properties. In the Code-tab I have written (I have tried many combinations): Public Dim class1 As myDLL.myClass. I have used the Public-keyword because it complained that class1 was declared private. In the textbox-controller I have written: =code.class1.myMethod(params). But it doesn't work. The text-box writes: #Error and I get the warning:

Build complete -- 0 errors, 0 warnings

[rsRuntimeErrorInExpression] The Value expression for the textbox 'textbox5' contains an error: Object reference not set to an instance of an object.

So it appears that class1 is not an instance of myDLL.myClass. I have tried many combinations and also with and without adding "Class name" and "Instance name" in the References tab of Report Properties.

Any suggestions ?

Thanks

Hi again,

I works now. I removed the code in the Code-tab and added the class to the References-tab under "Class name" and "Instance name". I then wrote: =code.InstanceName.MethodName(param) in the text-box and it works. I didn't have the "code" part to begin with, so that was my problem.

Thanks for your input. I appreciate it :-)
