I have an application that was developed in Delphi7 and I need to make a change in a certain form, but when trying to open this form to make these changes the following error window appears:
Because it is an old application (which I did not develop) and because I do not have a lot of language skills, I do not know how I can solve this error, would it be a library I need to add?
This error occurs because you probably do not have the component / library installed, if you do not have it, you should check the ignore all option so that Delphi does not automatically remove the object declaration from your source code.
If you access the "Project" menu and use the "Compile All Projects" and "Build All Projects" options, there is a chance that your project will have the component but not have it compiled.
In "Component" you can try to use existing resources to point the address of your component.
In "Project" you can try to access the "Options" option and in "Packages" check if your component is selected for use, or try to add it to the list again.
Complementing the response from @Jonathan Cani: Install% as% of this component is part of this package. Download here or replace the component with a similar one .. .
