Enable Internet Applications

Loading a web page containing the ImageXpress ActiveX component is only possible when using Microsoft Internet Explorer.

To optimize ImagXpress® performance within Internet Applications, consider setting color palette management and property persistence as follows:

Color Palette Management

Image color palette management in Internet Explorer is handled differently than in Visual Basic. In order for the ImagXpress ActiveX control to work in all environments, a property called ManagePalette is included.

When the ImagXpress control is used in Internet Explorer, the ManagePalette property should be set to False, to ensure that all ImagXpress controls will retain their individual color palettes.
In environments like Visual Basic and Delphi, the ManagePalette property should be set to True (Default), to ensure that all ImagXpress controls display the same color palette (the palette of the topmost control).

Using Persistence

When the Persistence property is True (Default), control properties set at design time are maintained at run time. In Visual Basic, the control’s property values store in the form’s .FRM file. In ActiveX Control Pad, the property values store in the .ALX or .HTML file. The size of the .ALX, .HTML or .FRM files can become quite large if you have many ImagXpress controls in your project because many of the property values are stored for each control.

For Internet applications, you want to keep your .HTML and .ALX file size as small as possible in order to decrease download time. You accomplish this by setting the Persistence property to False, then set your control properties at run time, instead of design time. This decreases the size of the .ALX or .HTML file, because you are setting only desired properties.
