TDbEngineErrorDlg.HookExceptions Method

Enables the TDbEngineErrorDlg instance, replacing the standard exception message at runtime.

Pascal
procedure HookExceptions;
C++
__fastcall HookExceptions();
Description

To display all unhandled EDBEngineError exceptions in a TDbEngineErrorDlg (rather than the standard message box), create a TDbEngineErrorDlg and call HookExceptions to enable it:

Copy Code
TDbEngineErrorDlg.Create(Application).HookExceptions;

 

Copy Code
TDbEngineErrorDlg *pDBEDlg = new TDbEngineErrorDlg (Application);
pDBEDlg->HookExceptions();

If you include this code in an application's project file, in an OnCreate event handler, or the constructor for the project's main form, the TDbEngineErrorDlg will trap and display unhandled EDBEngineError exceptions at runtime.
