Class not found up vote 0 down vote favorite I'm working on a code which is developed by another person exactly on the same PC that I'm using now.

When you created a new account, you are now using a fresh IDE. However, you did not provide that information in your question, it was later exposed in the comments of David's answer. –Jerry Dodge Mar 16 at 15:01 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote The message indicates that the design time package containing the named class has not been installed into your IDE. This is a devexpress component, and it may just be that you have not installed devexpress on this machine. share|improve this answer answered Mar 16 at 13:14 David Heffernan 430k27585952 This PC has not had a problem for running the code before.

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/36036568/delphi-xe3-error-reading-form-class-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.

I'm thinking I have to "Install components" or "Install packages" to get the standard toolbars back. Goto Project|Options|Packages. Check to see whether 'Borland Standard Components' is present in the 'Design Packages' list. If so, make sure it is checked. If not, press 'Add...' and browse to ${BCB}\Bin and select dclstd50.bpl.

Recently I have been told to support an existing Delphi Application in my organization. I have been fixing small code changes in the forms for day to day maintenance purpose.Since I do not have any formal Delphi background I have been stuck up with an issue since last few days. I am trying to open a form and I get a pop up saying "Error Reading Form".Further it says "Class TNumEdit not found. Ignore the error and continue? NOTE: Ignoring the error may cause components to be deleted or property values to be lost" Below this are three buttons for "Ignore", "Cancel" and "Ignore All".If I press "Ignore" button and open the form the Form gets loaded. Next when I do press F9 to run the program my application fails when I try to load this form.It gives me error message saying "Project raised exception. Class EAccessViolation with message 'Access Violation at address 00597E57 in module appname.exe. Read of Address '00000000' Process Stopped. Use Step or Run to continue" I ha
