SYMPTOMS
Calling the MAPIInitialize() function from a console application can block windows messages to other Windows applications.
CAUSE
The console application has not provided a message loop to allow the Windows Operating System to address the requests of other Windows applications.
RESOLUTION
Write the code as a Windows application or alternately try using the PeekMessage loop API call.
For more information on implementing PeekMessage loop functionality, please see the following article(s) in the Microsoft Knowledge Base:
74042 How to Use PeekMessage() Correctly in Windows
STATUS
This behavior is by design.
MORE INFORMATION
Code sample that demonstrates issue follows:
#include "mapix.h"
#include "conio.h"
void main()
{
HRESULT hrT = NOERROR;
hrT = MAPIInitialize(NULL);
getch();
}
- Build the code sample above as a console application.
- Run the application.
- Switch to the Control Panel and launch Date/Time
- Change the date and click OK.
Step 4 should close Date/Time, but it remains open and blocked until the (MAPIInitialize) application is closed.
