CoInitialize has not been called

[isosrl]

Hi,

I have a project (unigui 0.99.90.1291) with ADO components and Indy IMAP component that when compiled as Windows StandAlone works correctly; when I compile it as Windows Service and start the service it stops; in log a read the error "CoInitialize has not been called".

 

I have set ServerModule->AutoCoInitializa to True.

 

I run the service on my pc but the sql server is on another pc, so I try to change in Windows Service the account from "Local Service" to "Network Service", still the problem.

 

 

Any ideas ?

 

Thanks,

Francesco

Can you please send a sample project?

[Farshad Mohajeri]

Can you please specify where your ADO components reside? MainModule? DataModules?

Hi Farshad,

 

ADO components, Indy IMAP, UniThreadTimer reside in ServerModule since I need to pool IMAP server and when I found new emails they are copied into SQL database for later use.

Main form is used only for SQL database and IMAP configuration, protected by the Login form.

 

Attached you can find the project.

 

It is not necessary to configure SQL and IMAP access, since if they are empty the project runs but does nothing.

Eventually password for login form is admin.

The project will pool the folder INBOX/RichiesteArticoli of the imap user.

Hi,

 

Since you are using your components it inside a ThreadTimer you must take care of all threading related stuff. Such as calling CoInitializeEx and etc.

Ciao,

I will check CoInitializeEx and etc.

 

Thanks.

Hi again,

I cannot get to run as WindowsService, I tried different use of CoInitialize/Ex with no success...

I came back to normal Windows standalone program, not a big issue.

 

Thanks for the support.

I found the problem in your issue. Problem here is that Ado components are placed on servermodule. I will try find a workaround for it.

[Farshad Mohajeri]

I will add a workaround in next build.

Hi Farshad Mohajeri

An Exception has occured in application:

CoInitialize has not been called

I am using Delphi Community 10.3.3 & the unigui downloaded trial

ADO connections/ ADoDataset are on the Sever Module

What was the workaround ?

Hi

I have tried placing the ADO components on the ServerModule/MainForm/Data Module.

Can compile as a stanalone with no error but get the CoInitialize has not been called then localhost:8077

How can I solve this problem ?

UniServerModule -> AutoCoInitialize = True ?

Yup, that solves the problem. I am now able to display LIVE MSSQL Express data to localhost:8077 via a UniDBGrid :-)
