3. Application.ProcessMessages

I always found the sleep command in ObjectPAL very useful. The following code does about the same thing in Delphi. It makes use of GetTickCount which is a Win32 API call that retrieves the number of milliseconds that have elapsed since the system was started, up to 49.7 days.

I have an application in Delphi 1-7, using BDE. Is there a way that I can upgrade the BDE so the can work with MSSQL 2005 or 2008. They work fine if MSSQL2000 is is used. Am I on a dead end or there is still hope?

The window region determines the area within the window where the operating system permits drawing. The operating system does not display any portion of a window that lies outside of the window region.

Simply use this function in the FormCreate event:

15. Electronics Corner: Coding for 13 and 26-Bit Values The world of electronics is a fascinating place. Thousands of devices are available as tiny integrated circuits that can do truly amazing things. Some depend upon an external input to "program" them - or change their outputs. Here we explore one interesting aspect of dealing with these gadgets, some fast, low-level math routines that deal in unusual numbers of bits.

17. Get the XP Look in Older Versions of Delphi

Windows XP incorporates a "theme manager," and includes a newer version of comctl32.dll. Together, they help produce the unique XP Look. Later versions of Delphi are equipped to take advangage of this. But what if you have to maintain a Delph 5 application, and would like to spruce it up to look like a real XP program?

21. Quoting Your String (QuotedStr and AnsiQuotedStr) When you need to put quotes, single or double, or even another character, around a string there are two methods to lend a hand: QuotedStr and AnsiQuotedStr. QuotedStr will put single (') quotes around your string or variable. The other function you can call is AnsiQuotedStr which adds double quotes.

25. TADOTable: When The Obvious Can Be Wrong!

With the introduction of support for ADO Database access, Borland gave us TADOTable, a quick, easy-to-use component to begin the job of outfitting an existing application with a newer database. But TADOTable is no TTable! It comes with some baggage you can do without.

26. TStringList - Maximizing Performance Before adding many new entries to a TStringList, set its Sorted property to false. Add all your entries. Finally, set the Sorted property back to True (if desired). Sorting is expensive, in terms of macnine cycles. By leaving the Sorted property set to True, you force the TStingList to re-sort itself after each entry. This can significantly slow things down. This applies to TStrings, as well, and all components that have a TStrings property, like TListBox, etc.
