Databases Paradox: DB path too long: Paradox 5.0 is crap. Solution, is to convert table from Paradox 5.0 to 7.0 which is more stable. Table conversion from Paradox 5 to 7: The BDE will create the lowest level table possible, based on the features you specify for the table. To force a conversion from Paradox 5.0 to 7.0 add features such as Decending Indexes, Referential integrity. Networking shared Db problems: You need to use BDE Administrator to set a path to a net file. Start BDE Admin, Click on the Configuration Tab, Click Drivers>Native>Paradox. In the Net Dir Type the path to a network directory (must not be the same directory as the DB tables) and use UNC path. Next under Configuration again, System, INIT and set LOCAL SHARE to TRUE.

Delphi Studio 2005 Delphi 3rd party components: LMD Tray icon - Transparent animation Normally an icon transparency is defined by the color of the bottom left pixel. The LMD tray icon however takes bitmaps as its source through an LMD image list (or an LMD IML connector to a Borland IML). These bitmaps should be given a white background as this is the colour used for transparency. For white in the rest of the icon use a just off white-shade. Active X: Installing Type Libraries To create a Pas file & install a Type Library for an Active X control, goto: Component\Import component\Active X control Active X dlls (normally in Windows\System32) and with _TLB file indicators are I think are already listed although others can be added _TLB Dlls can be added here by providing filename. When ready choose 'create unit'. Then go and make a cup of tea & wait a long time. Eventually the pas file will be created and imported in to the BDS import directory. See also: EE notes |

Network Network connections: What is a 1394 Net Adapter (its a firewire!) Windows XP users might notice a new network device labeled 1394 Connection on their system. This network device is actually your FireWire card. Although most users use FireWire to connect video and storage peripherals. The reason Windows lists firewire cards as network devices is because they ARE network devices. If you can have 2 PCs or MACs with firewire cards, and you can network them by simply plugging a FW cable from one PC to the other, no hub or switch is necessary. Firewire= 400Mbps network. |
