• Internet Explorer Development Develop Activex to call from JScript

  I want to develop an ActiveX so that I can access it from the JScript. I know there is a method CreateActivex() in JScript. Do I have to add special interfaces for my activex, in order to use this method. Thanks The only interface required is IDispatch , which is so ubiquitous it goes without saying. Don't forget that COM objects and ActiveX controls must be registered as Safe for Scripting or IE will complain when you try to instantiate the control from script in an HTML page. It's easy to do this in the registry, but a robust control will also implement IObjectSafety to encode the author's intent. And, if you plan to use the control widely or distribute it publicly, you certainly should sign the control after you have f ...Show All

• Windows Forms Windows Forms Progress/Status Bar

  Hi, I need to implement a progress bar along with a status bar. I need to show the progress and at the same time i need to change the contents of the status bar dynamically based on what script is being executed. Some thing like : Processing Script1................. Processing Script2................. etc Can any body tell me the best way to acheive this Also i need to know if i can use a regular label control as a status bar Thanks Mahesh If you're preforming a lengthy operation you'll want to make sure you perform the processing on a background thread or the form will not be able update (defeating the purpose of a progress bar and a status bar...).

• SQL Server Odd FMTONLY statements

  Hi, I recently started using ADO for connecting to a remote SQL Server from Delphi. Prior to this I used BDE (Borland Database Engine). I noticed that all SQL communication seemed slow – only half the speed of using BDE! I ran a trace using the Profiler (from MS SQL Server) and noticed that ADO generated roughly twice the amount of traffic compared to BDE. Every SQL statement (SELECT, INSERT and UPDATE) send from my application was preceded by the exact same statement encapsulated in ‘SET FMTONLY ON/OFF’. -Example Start- SET FMTONLY ON SELECT * FROM TabelVersion SET FMTONLY OFF SELECT * FROM TabelVersion -Example End- Why are these odd statements being passed to the server ...Show All
