Thank you very much, I am going to try to explain my problem, my English is awfull but I think that enough. I have write a application with Sysbase PowerBuilder. This application connect with a oracle 8i database but first, show a validation user/password screen that connect with a Active Directory Microsoft 2003 server. The application works fine in a windows XP new fresh installation, just I need to install the oracle 8i client. ------ I am trying to run the application under wine. I am trying with ubuntu 8.10 distro and Fedora 10 (the lastes ubuntu and fedora) with wine stable 1.0.1 First I install java with wine, and all works fine (I need it for the universal oracle installer). After, I install the oracle 8i client ... that it is installed successfully .................. I try to run the application and it´s works .... the application start and show me the validation screen but after click enter with the user and password .... the application show me an error "Class name not found" .... making a debug with winedbg I could see that something is wrong with the ODBC /OLEDB so I try to install Winetricks MDAC 25/27/28 ... I try all, (I have a vmware virtual machine and I have make several snapshot and reserse it trying all the MDAC). When I install MDAC27 .... the "Class name not found" error disappears .... but my application show me ... Error: When calling to the external object function properties. On line 37 of the function f_ldap_logon of the object f_ldap_logon this is the function (see the bottom): and this is the line 37 ---> adoConnection.Properties("User ID", ls_user) and wine show me the error: err:ole:CoGetClassObject class {6c736db1-bd94-11d0-8a23-00aa00b58e10} not registered err:ole:CoGetClassObject no class object {6c736db1-bd94-11d0-8a23-00aa00b58e10} could be created for context 0x1 But .... this key is not in my windows XP and others, I put it on google "6c736db1-bd94-11d0-8a23-00aa00b58e10" and it is something realative to OLEDB but ... I dont know what is happening. Please help me if it is possible. Thanks you very much.
