Hello Experts :-)

I am a Delphi programmer. I use  TQRAngledLabel, it used to work fine, now I got this error message.

How could it happen?

I have source code for TQRAngledLabel but have no experience in writting components, what should I look at?

Thank you

This error may tell you:
1. You have changed delphi version
2. you have changed component version

Are you having this problem at runtime or designtime?

I would check it the"current version of the component actually has that propery and if not edit the .DFM file with notepad to remove the property from there also..

If the property does exist in the code but the designtime editor does not see it then check to see it is in the "published" part of the type.

Also "installing" the component/package(.dpk) again in Delphi might solve the issue.

there is no property FontSize in TQRAngledLabel

there is a property Font

however, the size of the font is defined by the property Height
which is a negative value

this can only happen if the dfm was messed up ...
by delphi or by editing the .dfm file manually

the delphi IDE will give a warning if it finds properties which have no "code counterpart"
saying this property does not exist

you can ignore these properties.

this can happen with using a newer version component in a older version of delphi too
ignoring the new properties allows the delphi ide to create the "old version"

>> just hit ignore and hit yes when asked to remove the property

simply edit the form in text mode using notepad and remove the offending property save and all is well.

It is because of a new version of the component and the property is either not exposed or present.
