Hi,

I'm no more able to monitor Mydac 5.70.0.42 apps !
Can someone confirm this ?

I can not reproduce the problem.
Please check that the TMySQLMonitor component is used in your application and the TMySQLMonitor.Active property is set to True.

I'm sorry but TMySQLMonitor.Active is set to true.
I have also installed "dbForge Fusion for MySQL, RAD Studio add-in Standard". Could it be the problem ?

I can not reproduce the problem. Please try uninstall dbForge Fusion for MySQL and check if the monitoring works.

I've remove dbForge Fusion and the problem persists.
I've tried with MyDC 5.70.0.43 and the problem persists.

Could it be related with the fact I'm running on a 64bit operating system ?

DbMonitor is a 32-bit application and MyDAC is 32-bit, therefore these applications are run on a 64bit operating system in 32-bit mode. Therefore the version of the operating system should not affect on the work of DBMonitor.

Is there a way to "debug" this deeper ?

Please tell me, when you run DBMonitor and after this run an application that contains active TMySQLMonitor, is this application added to the Process list of DBMonitor?

swierzbicki · Post by **swierzbicki** » Thu 18 Dec 2008 17:27

No, nothing is added to the Process list !

Please, set a breakpoint in the DBMonitorClient function of the DBMonitorClient unit and check if this function returns nil or not.

Hi Dimon,

On a Vista64 system, DBMonitor class is registered here :

Code: Select all

HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{89F49E65-F6E0-11D6-9038-00C02631BDC7}

Function GetDBMonitor (DBMonitorClient unit) will check for this key :

Code: Select all

HKEY_CLASSES_ROOT\CLSID\{89F49E65-F6E0-11D6-9038-00C02631BDC7}

There is either a problem with the DBMonitor installation (write infos in another place) or a problem with Function GetDBMonitor (look at a bad key)

I've sended you a modified DBMonitorClient unit that is working on both Win32 and Win64 OS.

I've also found this when doing some google search (this might helps) :

Question
I have an ocx that I have registered on Vista 32 and can use without a problem in Delphi. When I attempt to add it to a form in Delphi 2007 (December Update) on my Vista 64 machine I get a "Class not registered". If I click on the details button of the error I get the following info.
I have manually used regsvr32 to register it and it says it succeded in registering it.

Answer
In Vista 64 there are two regsvr32 files. One is located in your %SystemRoot%\System32 which is actually the 64 bit regsvr32. Since you are registering a 32-bit ocx you will need to use the regsvr32 in %systemroot%\Syswow64 folder, this is the actual 32-big regsvr32. So first browse to that folder and then use regsvr32.

Thank you for the detailed information and your advice. We will fix this problem. This fix will be included in the next MyDAC build.
