The following code works as a 32-bit application, but not as a 64-bit program. Is there something wrong?
That is, the path used at design time is not replaced only in a 32-bit application, but in a 64-bit application.

hello,

We cannot reproduce the problem in both 32-bit and 64-bit applications: the sqlite3.dll library is loaded from the specified path with no errors, if there is a correct library version in this path. Please make sure that there is a 64-bit version of the library in the folder with the application on the 64-bit platform.

Well, I've found the problem. If I remove the path to the sqlite3.dll library at design time, the new path is implemented on the 64-bit platform run-time correctly.

Only, I must manually set the path to the design-time every time.

However, also the path specified at design time to the sqlite3.dll library will be replaced on the 32-bit platform.

Can it tell someone me?

hello,

This error can occur only in the case if you have set a connection in design-time. In this case, when running the application, there will be an attempt to connect to the DB with the help of the library specified in run-time (the path that is already set for searching the DLL will be used). I.e. you should either disconnect in run-time before building the 64-bit version of the application, or set the UniConnection.Options.KeepDesignConnected to False in order that automatic connection to the DB doesn't occur at running the application

Hello,

I have of course taken at run time no database connection is, but only will be connected at startup.

The option KeepDesignConnedted: nothing causes of run-time = false.

hello,

Please specify the exact versions of your UniDAC and XE2

hello,
UniDac is version 4.2.7 and Delphi XE2 is version 16.0.4504.48759.

Hello,

We checked this behaviour on the similar versions of IDE and UniDAC and found no problems that were described. Please send a small project demonstrating the problem to alexp*devart*com
