Converting from Standalone to ISAPI in Delphi

Lets take the Guess demo as an example:

program Guess;

uses
  Forms,
  IWMain,
  Main in 'Main.pas' {formMain: TIWFormModuleBase},
  ServerController in 'ServerController.pas' {IWServerController: TDataModule};

{$R *.res}

begin
  Application.Initialize;
  Application.CreateForm(TFormIWMain, formIWMain);
  Application.Run;
end.

Change the program clause to library.
Remove the IWMain and Forms from the uses clause.
Add IWInitISAPI to the uses clause.
Remove everything between BEGIN..END.
Add IWRun between BEGIN..END.
Add GetExtensionVersion, HttpExtensionProc, TerminateExtension to the exports clause.

Your program should now look like this:

library GuessDLL; 
 
uses 
  ISAPIApp, 
  IWInitISAPI, 
  Main in 'Main.pas' {formMain: TIWFormModuleBase}, 
  ServerController in 'ServerController.pas' {IWServerController: TDataModule}; 

{$R *.RES} 
exports 
  GetExtensionVersion, 
  HttpExtensionProc, 
  TerminateExtension; 

begin 
  IWRun; 
end.

Converting from StandAlone to ISAPI in CBuilder

Open your bpr file in a text editor such as NotePad.

1. Change the EXE to DLL
2. Locate the line that says -tW -tWM"/> and add "D" after the first W
3. Change c0w32.obj to c0d32.obj
4. Save the changes and open the updated project file in C++ Builder
5. Remove IWMain and Forms from the uses clause
6. Add IWInitISAPI to the uses clause.
7. Build the project
