Unit34.dfm

Sometimes see this error if third party components are not installed and up to date. For example updating to a new Delphi release but not updating third party components like FastReports but just using what was already installed.

I agree with @Brian Evans, it is likely that BergSoft components or FasteReport need to be updated.

the project compiles without error despite the fact that it contains about twenty forms using the same components.

but unfortunately I can't view and modify the said form with D11.

i deleted components one by one from the dfm file ...

when i deleted nextdbgrid the form was opned without error in the IDE.

So..i confirm ..the problem was with nextdbgrid component.

 

thank you very much form you help.

The IDE loads designtime packages along with runtime packages before it makes instances of components for the visual form designer. It doesn't do that when compiling. Making sure third party components are installed, reinstalled or updated after installing a new Delphi can help make sure everything is all hooked up and working so they load into the IDE and work without issues in projects that use them. Not sure what the underlying issue is just that I have seen similar errors and re-installing third party components solved it. Guessing it fails to load something but ends up showing an out of bounds error for some reason.
