multiple .cs files using shared method, using form name as a parameter

Mike Pischke

Take a look at this basic example: public static void headbar(string formname, string heading) { string oldheading; oldheading=formname.Text; formname.Text=oldheading+" "+heading; } Then when I initiate a form (say "myform"), I would: headbar("myform","testing"); The intended functionality here is to have this common method be used to add verbiage to the .Text property of a form, where I'm providing the form name as a parameter. (There is a 'bigger' issue at stake, but this simple example illustrates what I don't know how to accomplish). The code above won't compile, because "Text" is not a property of the string variable "formname". But the contents of "formname" would have a "Text" property. How would I change my code above to work as intended?

Accepted answer

here is your code with a slight Change

   public static void headbar(ref Form formname, string heading)
        {
            string oldheading;
            oldheading = formname.Text;
            formname.Text =
            oldheading + " " + heading;
        }

Scratch my last question. I'm good. I had too many parameters in my call - idiot. Thanks for your help, as this issue is closed.

Thanks Roei. I'm almost there, just one followup: I have one final syntax issue, and I cannot find anything out there on the web related to this: I populate the formname field with a string (formname="myform";, for example) before calling this method. I've tried putting quotes around this, no quotes, and I cannot get the syntax right with how to call the method where "ref Form formname" is a parameter. I'm unable to see the errors happening (long story, and that makes my life difficult), but can you provide to me the details on how to call this method, with respect to how to provide the form reference?

Using a reference parameter does appear to get me closer, but it still won't compile for the same reason. I'm not sure if this is a syntax issue or what. But again, wanting something simple like: public static void headbar(ref string formname) { formname.Text="test" } where I can pass the formname and set the text property is what I'm looking for how to do. Can anyone be more specific as far as how to accomplish this? (The above will not compile because there is no .Text property of a string, but there is a .Text property of the contents of the string.)
