how to retrieve the captions of all open windows that belong to certain class+delphi

hi there

i need a function in delphi where i can pass as a parameter the name of a class e.g

ExploreWClass and CabinetWClass, and get a result back as a string of all the window captions that belong to this class.

for example

if two folder windows are open in my desktop

1) C:\Documents and Settings\user\Desktop\delphi
2) C:\Documents and Settings\user\Desktop\websites

i want the fuction to return me the following:

result=C:\Documents and Settings\user\Desktop\delphiC:\Documents and Settings\user\Desktop\websites

if 5 windows of a certain class are open i need as a result the concatenation of all these window captions

i have some code below. hope it helps

thanks

function Get_foldercaption(const thestring: WideString): WideString;
var
  foldercaption:cardinal;
  foldercaptiontext,foldercaptiontext1:array[0..255] of char;

begin
     
     //ExploreWClass and CabinetWClass should not be hardcoded like here but passed as parameters in the function
      foldercaption := FindWindow('ExploreWClass', nil);
      //foldercaption1 := FindWindow('CabinetWClass', nil);
      GetWindowText (foldercaption, foldercaptiontext, 256);
      Result := foldercaptiontext
     
End;
