I have used :
Button btn = (Button)this.Controls.Find("button" + strLetter.ToUpper(), true) [0];
to find a control named button.a

How would I find an instance of a class that I have created named myIHCPanelA.
This is not a control so I can't do this:
Specimen sp = (Specimen)this.Controls.Find("myIHCPanel" + strLetter.ToUpper(), true)[0];

When you say 'find an instance of a class', when you create the instance you should have a reference to it, when your instance goes out of scope or you explicitly dispose of it then it will be garbage collected and will no longer exist, so generally speaking if you dont have a reference to it and need to 'find' it then it wont even exist for you to find.

Thanks for the reply.

The instance isn't out of scope, I created it just after loading my form. What I am doing is iterating through a recordset and when I find the line that references specimenA (strLetter) I need to the populate myIHCPanelA.name, myIHCPanelA.description, etc. for several specimens a-x.

i see.

Can you not add them to a dictionary...

Dictionary<string,YourType> dict = new Dictionary<string,YourType>();


dict.add("A",instance);
dict.add("B",instance);
dict.add("C",instance);



then ref them via
dict["A"]

etc...
