Hi Eric, The difference in version number is historic: originally, Revolution wasd an alternative IDE for the MetaCard engine. The engine and IDe versions didn't match until Revolution 2.7 came out. In this case, Revolution 2.1.2 was built on top of MetaCard 2.5, and the 'version' global property re...

Hi Dalkin,

MySQLrequires a setup to run, and this may get messy. If the database is single-user and local, you might be better off using the SQLite driver that comes with Revolution 2.8.1

Hope this helped,

Hi mluka, You can set the 'textStyle' property of individual chunks: set the textStyle of word 2 of line 3 of field "foobar" to "bold,italic" Or, you can play with the 'htmlText' property of the field to achieve the same result by inserting <b>...</b> tags in the proper places. When you're working w...

Hi Homer, The line separator differs between platforms: Unix prefers linefeed (ASCII 10), Mac Classic prefers carriage return (ASCII 13, and Windows prefers carriageReturn+lineFeed (ASCII 13+10). When you use the 'URL' keyword to create files, Revolution will take care of this for you: put theDataTo...

Hi Paul, As Mark suggested, the 'revdb_querylist'/'revDataFromQuery' functions may do the trick more quickly, as the concatenation is done in compiled C++ code rather than the Revolution scripting language. If these functions are still taking too long, you could try and fake a multi-threading approa...

In 'standard' SQL, strings are opened and closed with apostrophes, not quotes - some SQL databases may allow both quotes and apostrophes, but Access is not one of them. Try 'escaping' the apstrophe instead: on mouseUp put "Update Campers Set LastName='" & SQL_Escaped(fld LastName) & "' where ID=" & ...

Hi Paul, Before I answer your actual question, here's a tip with regards to properties and the inspector palette: iif you want to see the actual property names as used in the programming language, modify the preferences. In the 'General' tab, at the top you see a radio set to control whether the pro...

Hi Kai,

To force the geometry to be recalculated, go to the Card inspector, then to the 'Geometry' panel, and tick the checkbox "Update before opening card".
Strange that this isn't the default, but what can you do?

Hi Garrett, You can set the 'hilite' property of the menuitem: set the hilite of menuItem 3 of button "Foobar" to true You can only refer to menitems by number, not by name or label. Alternately, you can modify the 'text' property of the menu button: put "!c" before line 3 of button "foobar" put "!r...

Hi Kai, The database query linked controls provide a quick way to put together a user interface to an existing database. There are some tricks that can be applied to modify and refresh queries as you navigate result sets of other queries, etc. But it's not like FileMaker or Access and to get to the ...

Hi Kai, Open the Messsage Box - use the buttons at the top of this window to display the 'Front Scripts' panel - then tick the checkbox 'Show Revolution UI Front Scripts' - now you'll see a line 'revDatabase' appear in the list. You can doubleclick this to see how the database query linked objects a...

Hi Kai, Revolution is by nature a general-purpose development tool. Dataabse front-ends are far more likely to have fields with input masks, maximum length, automatic uppercasing etc. And even database vendor Progress didn't introduce a password field until Progress OpenEdge 10.1B in February of thi...

Hi Pradeep, This is Windows Vista and its user control for you: when an executable has not been 'signed' with a digital signature, it will warn the user that the publisher could not be verified and this might be spyware. From a recent post by Bill Mariott on the Use-Revolution mailing list: In order...

Hi Bjoernke, Thank you for writing this alternative - while some aspects of its look and feel are not my cup of tea, I especially appreciate the separate list field for related items, as well as the working history. However, when I ran this on Windows XP, the 'miniMe' version crashed Revolution when...
