Ignore the error and continue? Note: Ignoring the error may cause components to be deleted or property values to be lost. When I click Cancel, I get following message Error creating form: Class TMyClass not found. When I click OK now, pas file is opened only. In pas file MyClass unit is added (which conatins the TMyClass defination) and its path is also added in my search path (Ctrl clicking on unit name, takes me to the unit file) Everything is fine as per me. I don't know why I am getting this error and why am I not able to open this dfm file in RAD studio?

Cut down .pas and .dfm please. –David Heffernan Nov 12 '13 at 8:08 You've got this tagged both as Delphi 7 and Delphi XE4. Which is it? –hvd Nov 12 '13 at 8:10 3 Actually, that may not be relevant. Have you made sure to install the TMyClass component so that you can use it at design-time too? –hvd Nov 12 '13 at 8:11 @hvd - Its Delphi XE4. –user1556433 Nov 12 '13 at 8:12 add a comment| 1 Answer 1 active oldest votes up vote 8 down vote accepted To create the component (that you placed on the form) Delphi IDE should know it by name and have its class loaded into memory. That means - it should have that component compiled into binary runtime package and that corresponding design-time package should be loaded into IDE and during the loading it should call RegisterComponent. Usually this all is done during the library installation. So if you have that library for Delphi 7 now just install it for Delphi XE4 as well. If your library does not have installer or that installer does not k
Error Reading Form
Class XXXX not found. Ignore the error and continue? NOTE: Ignoring the error may cause components to be deleted or property values to be lost. where: XXXX is the name of a component. Cause: The form is using an Active-X component which is not available. Typically this indicates that the Delphi was originally written on one pc where an Active-X component was available but is being recompiled on a PC where the component is not available. Remedy: DO NOT CLICK "IGNORE". http://stackoverflow.com/questions/19923926/error-opening-a-dfm-file-class-xxxx-not-found If you ignore the error then the component is replaced by a panel, and thus all functionality associated with it will be lost. Instead click "Cancel". Identify the Active-X component which is missing. This is the name given in the error message.For example: Class TWebBrowser not found. indicates that the active-X control "TWebBrowser" is missing. In some cases the Active-X component may http://www.cryer.co.uk/brian/delphi/error_class_not_found.htm be available on the PC but not imported into Delphi.For example TWebBrowser can be made available by importing "Microsoft Internet Controls" - full instructions for TWebBrowser can be found here. In general the procedure is to: On the "Component" menu select "Import ActiveX Control..." Scroll through each control listed until the missing control is listed against "Class names", this is the control that you will need to install. Once you have found it click the "Install..." button (not the "Create Unit" button), and confirm any prompts which follow. Restart Delphi and reload the offending project. If the Active-X component is not available on the local PC then you will need to identify where it originally came from and arrange to obtain a (licensed) copy of it. These notes are believed to be correct for Delphi 6 and Delphi 7, and may apply to other versions as well. About the author: Brian Cryer is a dedicated software developer and webmaster.

Based on the picture below, what is the most logical reason for the errors out side of the class itself? How many options do I have for locating this class?

And also XYZ? Take a look in the type section in the form.pas There are all components used in the form. It seems that the form contains components that aren't alredy installed into the ide, so their class is unknown. If you're trying to compile a project created by someone else you should already have in the uses clause a list of unit related to these components. Just check in your project directory if there're these files and eventually install them. 0 Messag
