    text
    <p>I have an XE2 DataSnap server (Windows service) which uses a 3rd party out-of-process COM component within it's methods. Being COM, I understand it requires the CoInitializeEx and CoUninitialize commands around the statements. My DataSnap server is working great, other than the fact that when I stop the service, I always get an 'Application Error' message in the Event Log, along with an 'APPCRASH' information message. I'm sure this is related to the CoInit.. commands. I have none-DataSnap Windows service apps that use the COM component and stop fine with no errors.</p> <p>I've tried placing the CoInit/CoUninit commands in various places such as ServiceStart/ServiceStop, DSServerClass.OnCreate/DSServerClass.OnDestroy, and at the top/bottom of each server method function, but the crash still occurs when the service is stopped. If I don't call any methods on the server then the service can be stopped with no errors.</p> <p>Can anybody show me where CoInit/CoUninit should be placed for multi-threaded DataSnap services? Also, should I be using CoInitialize or CoInitializeEx, and which parameter is appropriate - COINIT_MULTITHREADED, COINIT_APARTMENTTHREADED etc?</p> <p><strong>Event Log Error :</strong></p> <pre><code>Faulting application name: X365EXHS.exe, version: 1.0.0.0, time stamp: 0x51ba3d97 Faulting module name: X365EXHS.exe, version: 1.0.0.0, time stamp: 0x51ba3d97 Exception code: 0xc0000005 Fault offset: 0x00006138 Faulting process id: 0xed4 Faulting application start time: 0x01ce687fcfde7812 Faulting application path: C:\DEVELOP\X365EXHS.exe Faulting module path: C:\DEVELOP\X365EXHS.exe Report Id: 1f933086-d473-11e2-8cab-005056c00008 Fault bucket , type 0 Event Name: APPCRASH Response: Not available Cab Id: 0 Problem signature: P1: X365EXHS.exe P2: 1.0.0.0 P3: 51ba3d97 P4: X365EXHS.exe P5: 1.0.0.0 P6: 51ba3d97 P7: c0000005 P8: 00006138 P9: P10: Attached files: C:\Users\JonathanW\AppData\Local\Temp\WERF44F.tmp.appcompat.txt </code></pre> <p><strong>Update :</strong></p> <p>With more testing I've found that the Access Violation on shutdown only occurs when my DataSnap server is started with the HTTPS protocol, bound to an SSL certificate. It uses the OpenSSL DLLs libeay32.dll and ssleay32.dll so could these be the issue? If I run the server with HTTP (no SSL) then it never AVs when shutdown.</p> <p><strong>MadExcept Stack Trace</strong></p> <pre><code>date/time : 2013-06-15, 09:16:56, 113ms computer name : JW-XT2 user name : JonathanW &lt;admin&gt; registered owner : JonathanW operating system : Windows 7 Tablet PC x64 Service Pack 1 build 7601 system language : English system up time : 1 day 12 hours program up time : 44 seconds processors : 2x Intel(R) Core(TM)2 Duo CPU U9400 @ 1.40GHz physical memory : 2749/5008 MB (free/total) free disk space : (C:) 5.22 GB display mode : 1024x768, 32 bit process id : $1134 allocated memory : 19.61 MB executable : X365EXHS.exe exec. date/time : 2013-06-15 09:14 version : 1.0.0.0 compiled with : Delphi XE2 madExcept version : 4.0.7 callstack crc : $00000000, $00000000, $00000000 exception number : 1 exception class : EAccessViolation exception message : Access violation at address 004061A4 in module 'X365EXHS.exe'.

    1. COCould you perhaps provide the details of the APPCRASH/Application Error messages from the event log? Do you compile with MadExcept?

    2. COHi, I've added the event log errors above. I'm not familiar with MadExcept.

    3. CO0xc0000005 is an access violation. You're probably calling CoUninitialize too early (before all destructors are done using COM, etc). For MadExcept, have a look : http://madshi.net/madExceptDescription.htm (there's a free version available - it's really of infinite help when tracking down things like this)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
