Delphi 2010

I am writing a component that requires the use of both the units

DesignIntf, DesignEditors

When i build my package, i get the error

File not found: 'DockForm.dcu'

When I add "designide.dcp" to the "requires" section of the package, it builds and compiles just fine.

HOWEVER, when i add the component to a new project (in design time, it works. I can change all the properties, etc......BUT, it does NOT work in runtime.

When i run the application with the component on the main form, i once again get the "
"File not found: 'DockForm.dcu'" error

Delphi 2010

please help

thanks

For me?
First thing to do is to look for DockForm.dcu, put it in the folder where your project files are located.
Second, if DockForm.dcu, does not really exists, or not found, I'll go to project options, packages, then removed the packages that calls DockForm.dcu.

Go to Tools->Environment options

Make sure to include the path of DockForm.dcu in the Library path or DockForm.Pas in the Browse Path

systan:

Of couse, it exists. Its part of the Delphi 2010 Runtime packaging. You get the DCU, but not the Pascal file, just like Proxies.dcu.

I can't remove the packages that call DockForm...because it is a Unit that calls it ToolsApi.pas, which is needed in my component for doing custom property editors.

@ewangoya:  i assume you mean the component package and not the application the component resides on. The path is in the component package.

this is not a project, this is a component. I can't make my users path the component to whereever DockForm.pas resides.


Neither of these answers is what i am looking for.

I believe what i am looking for is the fact that Dockform.dcu is not allowed for runtime, but for designtime only. Therefore i need to add the code somewhere in my component that checks that the component is being used in designtime only, and not runtime.

The property editors are not used at runtime, only design time

It  looks like you need to segregate the design-time code from runtime code
