Outlook title set label and trusted encoding label

Microsoft Outlook Title Settings tab

The Outlook Title Settings tab, as shown in Figure 13-3, shows an important set of options. Fortunately, these have a simple and intuitive classification; You use this form to specify which encodings various categories can use, depending on the requested operation and application at the same time as the requested interface type. applications, macros, external programs, and other knowable files can use three different interfaces to request outlook for services, as follows:

Outlook object mode. Outlook object mode allows you to use the data stored in the Outlook area to use a set of built-in interfaces that can be used in any language to support COM. In most cases, people balance this object pattern and write the code to VB or VBA to complete.

Simple MAPI (datagram Delivery application interface). MAPI is divided into two types: Simple MAPI and Extended MAPI. Simple MAPI enables developers to add basic messaging capabilities, such as sending and receiving messages for their windows-based applications. Extended MAPI allows for more control of the application and is the only way an external application can use Outlook's data without triggering the Outlook Object Schema Wizard.

CDO (Collaboration data object). CDO provides messaging and collaboration capabilities. CDO allows you to assign jobs in a schedule, find contacts, and perform other tricks. CDO 1.21 is in fact a client-side COM knock-Call package program for the MAPI repository, and any language that can use COM can use CDO. CDOs can do most of the work, not all MAPI functionality (but more than Simple MAPI). Do not confuse the CDO here with the Exchange Management CDO (CDOEXM) or as part of Exchange and windows, but with a functionally different CDOSYS knowledge base.

Each possible operation (using CDO to send items, using Simple MAPI query address book entries, and so on) is independently controlled. When the third party software that is installed on the client wants to do some action, your specified operation is efficient: the client not only automatically requests (this applies to Outlook 2000 without security updates), makes a request rejection, and also alerts the user (the default action for Outlook with security updates).

Microsoft Outlook Trusted Coding Tag

The trusted coded label doesn't look good, so I'm not going to show it here. It contains a list box and two buttons: Add and delete. You use these buttons to add or remove COM external programs from the list, and the Outlook client trusts (in other words, allows to run) any COM external program in the list. However, remember that specifying an external program on this label does not allow it to run, nor does it mean that it is installed on the client. Setting up an external program here simply means that the external program has a direct call to the Outlook object pattern without the need to trigger the Object Schema Wizard. External programs calling CDO still depend on the wizard. Here are some nuances that use this label. First, you can only use the specified Outlook external program, for example, a Microsoft Word external program to invoke the Outlook Object mode feature is not available. Second, if you replace a trusted external program in an updated version, you will need to remove the old version from the list and add a new one, although two versions have the same file name.
