SUMMARY
Many Visual FoxPro developers might not be aware that the Active Messaging library exists for them to use as an extremely robust alternative to canned mail messaging API (MAPI) controls. This article is designed as part of a short (non-interdependent) series intended to provide Visual FoxPro developers with information, development tips, and useful snippets about the Microsoft Active Messaging Library.
This article introduces some aspects of working with a Message objects Fields Collection by providing a short code snippet demonstrating how to cycle through the Fields Collection of a sample Message.
MORE INFORMATION
Cycling through the fields collection can be particularly useful when trying to debug a Messaging application. This is especially true if this method is built upon to allow walking the collections of two different messages simultaneously and finding the differences between them.
* AM_FieldData.PRG * ---------------- * *Create a MAPI Session object then Logon. The Logon dialog can be *bypassed by providing a valid ProfileName as the first parameter *(as a string) to the Logon Method as seen below. objSession = CREATEOBJECT("mapi.session") objSession.Logon("Stevekl") *Get a sample message - for this example we'll take whatever is at *the top of the Inbox objMessage = objSession.Inbox.Messages.GetFirst objFieldsColl = objMessage.Fields *A key component of a Message Object is it's Fields Collection. The *Fields Collection is composed of a variable number of Field Objects *that each possess the properties: Name, Value, Type, and ID intFldCnt = objFieldsColl.Count ctrThisField = 1 FOR ctrThisField =1 TO intFldCnt *Display Name, Value, Type, and ID properties of the Field Object DO CASE CASE TYPE("objFieldsColl.Item(ctrThisField).Value") = "C" strValue = objFieldsColl.Item(ctrThisField).Value CASE TYPE("objFieldsColl.Item(ctrThisField).Value") = "N" strValue = ; ALLTRIM(STR(objFieldsColl.Item(ctrThisField).Value,30,10)) OTHERWISE *There is a potential that a field may contain data types *not support for display by Visual FoxPro. strValue = "Not Displayed" ENDCASE MESSAGEBOX(; "Field #" + ALLTRIM(STR(ctrThisField)) + " of " ; + ALLTRIM(STR(intFldCnt)) ; + CHR(13) + CHR(10) ; + "Name : " ; + objFieldsColl.Item(ctrThisField).Name ; + CHR(13) + CHR(10) ; + "Value: " ; + strValue ; + CHR(13) + CHR(10) ; + "Type : " ; + ALLTRIM(STR(objFieldsColl.Item(ctrThisField).Type)) ; + CHR(13)+CHR(10) ; + "ID : " ; + ALLTRIM(STR(objFieldsColl.Item(ctrThisField).ID,20))) NEXT ctrThisField *Clean up then exit objSession.Logoff RELEASE objFieldsColl, objMessage, objSession
