| ComponentOne True DataControl 8.0 > Adding True DataControl 8 to a Visual Basic Project |
When you install True DataControl 8, the following new components will appear in the Visual Studio’s toolbox customization dialog box:
True DataControl 8
True DataControl Lite
After you have opened a new or existing project in Visual Basic 6.0, you can add True DataControl 8.0 and True DataControl Lite to the Visual Basic Toolbox by following these instructions:
On Visual Basic’s menu, select Project, then select Components to display the Components dialog.
The controls will be listed as ComponentOneTrue DataControl 8.0 in the Controls page of the Components dialog box. Select the control's check box, and then press the OK or Apply button.
True DataControl uses the ComponentOne XArrayDB object to implement memory-based data sources (if DataMode = 1 – Memory Array). However, your project need not reference XArrayDB explicitly unless you manipulate such objects directly in code.
If you need to include an XArrayDB reference in your project, follow these instructions:
On Visual Basic’s menu, select Project, then select References to display the References dialog.
The object will be listed as ComponentOneXArrayDB Object in the References dialog box. Select the object’s check box, and then press the OK or Apply button.
True DataControl is based on ADO (ActiveX Data Objects), Microsoft object layer over OLE DB. You will most probably need the ADO library in all your projects. True DataControl does not add a reference to the ADO library to your project automatically; you must do it manually, if you need it.
The ADO library (ADODB) is not always necessary for True DataControl, but some True Data events use the ADODB.Error object, which is defined in the ADO library. Also, you need a reference to ADODB if you use constants defined there, such as adLockOptimistic, adOpenStatic, etc.
If you need to include an ADODB reference in your project, follow these instructions:
On Visual Basic’s menu, select Project, then select References to display the References dialog box.
The library will be listed as “Microsoft ActiveX Data Objects 2.1 Library” in the References dialog. Select its check box, and then press the OK or Apply button.
