The callbacks are called in context of a worker (secondary) threads. VCL lets you show standard VCL forms only in context of the primary VCL thread. So you need to use some interthread communication to pass the request to the main window. Alternatively you can use MessageBox() Windows API function which is not subject to these limitations.

Code snippets and extra (custom) samples are a benefit offered by Standard support level, which is available to those customers, who purchased a license for the product in question. The reason is simple - the registered customers have priority in support, and when our developers work on a sample for the unregistered user, they are not doing development, expected and requested by the registered customer. We realize that you might need a sample to continue evaluation. So we can offer you a sample code snippet for a fair price of 100 USD. If you are interested please send a request to sales@eldos.com and we'll give you a link to order the custom service.

Sincerely yours
Eugene Mayevski
