Access Violation from rtl170.bpl when connecting via TMyConnection in the IDE

[ConBran]

Hi,

I am attempting to connect to a database in the IDE and am receiving the following access violation:

Access violation at address 50061A36 in module 'rtl170.bpl'. Write of address 00000004.

This is only happening on my workstation, none of the other developers here get it.
It occurs when connecting the TMyConnection component, or, when executing a TMyQuery component, whilst in the IDE. If the application itself is running, I get no issues.

I am using Embarcadero XE3 Update 2, and V7.6.12 of the Data Access components for MySQL.

I tried a complete uninstall and reinstall of the IDE and MySQL Access, but the issue persists. This happens regardless of how simple the application is (one form with one connection, one query, one data source and one dbgrid).

I am trying to access the fields editor so I can replace a memo field in my DBGrid with just text, but I can't do it unless I can execute the query in the IDE - and doing that returns the above error.

Any thoughts on what this issue could be. Or, how to manually add the 'GetText' event the .pas and .dfm files without getting a 'Unknown Type TStringField' error (data.db is in my uses clause).

Thanks!

We can't reproduce the problem with "Access violation at address 50061A36 in module 'rtl170.bpl'. Write of address 00000004.".
Please download the latest MyDAC version (8.3.7) and check whether the problem is reproduced.

Hi
The same problem is during Bakcup inside the application ???
I compile the same code with previous mysql version and was working fine

I can't reproduce the problem with TMyBackup component for the latest MyDAC version (8.3.7).
Please try to compose a small sample to demonstrate the problem and send it to pavelp*devart*com.
