Default borland delphi component problem

Hi everyboody,
I've this problem: when i open a project with Delphi I receive this error box:
"Class TDBCheckBox" not found. Ignore the error and continue? Note: ignoring the error may cause components to be deleted or prperty values to be lost" and then "Error Creating Forms: Class TDBCheckBox not found".

I receive this message with: TDBCheck Box, TDataBase, TDBMEmo, TADVString.

How can I risolve the problem?

Help me!!
Thanks
Tonino

Default RE: borland delphi component problem

Just an idea :
go to your "Components\Install packages" IDE menu.
Here, check if your "Borland Database components" package (i.e. dcldb70.bpl) is correctly checked. If not, just try checking it. This should bring you back your TDBCheckBox and TDBMemo components.
Also check the "Borland BDE DB components" package (i.e. dclbde70.bpl) for the TDataBase component.
For the TADVString, I don't know in which one it is supposed to be included.

This kind of error can occur when you add external packages to your IDE and that certain class names are already in use. Maybe there's a kind of a conflict between certain packages.

Default ANYONE ELSE HAS AN IDEA ???

Sorry but I have no other idea, except maybe... reintalling Delphi.
Coz generally if your packages are well installed (and checked in the packages list as I explained you), then the problem is solved.

oh, yes. Maybe another idea : has your project been created with a previous version of Delphi ? if yes, then maybe the required units in the USES sections are not the same. But here the error message should occur only at compilation time. Maybe it can be a good idea to check inside these sections if you have all required units - this could produce errors.

Sorry again if my ideas didn't help you. Maybe someone else here will find the solution. Good luck

LörAn.

Make sure that the dcldbx0.bpl (where x is your Delphi
version) is in your PATH, such as Windows\System32

The reason you are getting that message is that the
internal compiler, when streaming in the form, is not
finding the dbcomponents in it's loaded meory, which means
that you probably do not have that package in the path so
it can be loaded on demand.
