Data Access error

[Pancary]

I have a UniGUI application that works perfectly with the code below, on my machine, but on the server it returns access violation error. A test using VCL works normally, both on my machine and on the server, but UniGUI I have this error.

 

procedure TMainForm.bt1Click(Sender: TObject); begin Dm1.sqlListaPrincipal.Close; Dm1.cdsListaPrincipal.Close; Dm1.sqlListaPrincipal.Open; Dm1.cdsListaPrincipal.Open; end;

Hi,

with extrem less information - its impossible to give a answer

 

 

What Database do you use

What SQL Statement do you use

and so on...

 

 

And your posting is unreadable ;-)

 

Better:

procedure TMainForm.bt1Click(Sender: TObject); 
begin 
Dm1.sqlListaPrincipal.Close; 
Dm1.cdsListaPrincipal.Close; 

Dm1.sqlListaPrincipal.Open; 
Dm1.cdsListaPrincipal.Open; 

end;

Try...

TUniServerModule - AutoCoinitialize - True

Thanks, but it did not work. Scenario: Oracle 10g, datamodule, TFDQuery, TDataSetProvider, TClientDataSet, TDataSource, TUniDBGrid. Sql, Any sql statement does not work. The access violation error occurs when you try to open the TClientDataSet, as an object not created. The strange thing is that as VCL works normal and on my machine too. The problem is only on the server.

I found the problem. It was necessary to declare MidasLib in uses.

 

Thanks.
