delphi-7

问题 Does anyone know which predefined functions (e.g ABS function) are included in the TEvaluator JCL class for Delphi 7? 回答1: There are none of the standard functions from Math.pas included. All that is implemented in the default evaluation parser are the operators or , xor , and , not , mod , + , - , / , * , < , > , <= , >= , = , div , cmp , bor , bxor , band , bnot , shl , and shr . (As many as I found in a quick check of the source, and a few I missed based on @David's comment.) You can add

This wonderful product shows a dialog with all the stack trace information and many many others for debugging purpouse.

Is there a way to access the information from the Eureka log programmatically ? I can use the bare delphi 7 or

问题 I'm sure this has been asked before, but I couldn't seem to find it. I use the code below to display an Image from a MS Access database. However, I would like know how to do the following: -Is it possible to take the procedure below and 'call' it in another form? Scenario : Three Forms. Three Tables, One Database. I access the tables via a TADOTable component and TADOConnection. Each form has a button (btnShowImage), to show the picture from the datbase. In order for it to currently work, I

问题 I found the brilliant Delphi Chromium project for embedding Chrome in a Delphi form. It works well in Delphi7 after a bit of hacking and I can get the demo app running. However when I do my own app with the component, I can't load my own url. I get a access violation. Chromium2.Browser.MainFrame.LoadUrl('http://www.example.com'); The TChromium component is working and I have all the DLLs in the right place, since if I set DefaultUrl it works fine. I have Chromium2 in a TPageControl page and
