After programming in Delphi since i

[RElmaaroufi]

After programming in Delphi since it first came out I have run into a new error that I have never seen before and which I do not understand. The error:

Cannot run project unless a host application is defined. Use the Run|Parameters .. dialog box.

I do not understand what needs to be entered in the Run forms.

Help.

Hi RElmaaroufi,

Unfortunately I can't help as I no longer use Delphi.

I was just very surprised and curious because you copied and posted the exact same wording that was posted here 12 years ago:

Hi Mikrom

Yes, because i found that the thread was closed, and I'm a newbie on this platform,

Any help please ?

Are you creating a DLL or an ActiveX control? Those types of projects cannot be run by themselves. Another program is expected to load the DLL or ActiveX control and make use of it. So Delphi is saying that you can't run your project. You can, however, tell Delphi to run another executable which is expected to load your project and then you should be able to debug it.

Ah okay, but how can I define tell delphi to run another executable, knowing that in my case I was given this project from my client, and I tried to execute it using the RAD STUDIO IDE, by opening the .dproj file and then execute (P.S the run button in delphi indicates that it points to a .bpl file).
