我的delphi7在電腦重裝系統(delphi7也是重裝)後，打開報表單元就報錯如上錯誤，忽略了就什麼都沒有了，請教是怎麼回事？我的是delphi自帶的Qreport 努力过，还有什么遗憾呢!

我已經裝了QuickReport,打開另一個報表就是正常的，可這個確不行，真是好奇怪! 努力过，还有什么遗憾呢!

在網上查了一下資料，介紹如下："The reason for my confusion is this. I have the following: TMyBaseClass = class(TFrame) with base class functionality, published properties etc. And then TMyDerivedClass = class(TMyBaseClass) All of the above was in a package. Compile and install the package with no problem. Drop a TMyDerivedClass on a form and I would get the error: "TMyDerivedClass.OldCreateOrder property does not exist" and the same for PixelsPerInch, TextHeight. In order to fix this I did the following: 1 - FUDGE...... Edit TMyDerivedClass DFM text to remove above properties. Recompile package and all is well Then replaced 1 with this...... 2 - BETTER (I think), but not understood Add the above properties to TMyBaseClass.... Colour me confused.....” 可我試了還是不行，可能是我的這個文件損壞，只好用以前備份的去恢復。 努力过，还有什么遗憾呢!
