When I save my bold object and then access it again, in the component there appears to be some unicode to AscII conversion. Can bold support UNICODE? If not how can I change my program to support unicode? Sham.

If you plan on using Bold in D2006 it should be the same, as there are no unicode related changes in D2006 compared to D7 in the Win32 personality.

I think you need to make a new package and add those units, then install in IDE, and WideString attribute should be available at design time.

Hi Sham, Yes, there are instructions in unit BoldAttributeWideString, you have to add it manually as you would for the custom attribute types: // To install this attribute type in your application, add the following to your // TypeNameHandle: // // ModelName: UniCode // ExpressionName: WideString // DelphiName: TBAWideString // ContentName: WideString // PMapper: TBoldPMWideString // Accessor: AsWideString // NativeType: WideString // UnitName: BoldAttributeWideString Regards, Danny Back to top sham Guest Posted: Fri Jun 16, 2006 4:38 pm    Post subject: Re: Unicode for BOLD Thanks for the instructions, I could not find any instructions in BoldAttributeWideString.pas. I have done as you said (adding type to typeHandle), and I see wideString as an attribute in the model editor. I have now set one of my class properties to WideString and generated the code. However, the interface unit for my project still contains has my property as TBAString (I was expecting TBAWideString). Am I missing a step?

I have evolved the database and the string column has been dropped and a new column has been created with character set ISO 8859. When running the app, I am still seeing the data entered (in Greek) as weird character when retrieved from the database. Do I need to change the tboldEdit components?

Do I need to change the tboldEdit components? I suspect you are correct and it's the controls that don't really support unicode, try to test with TNT controls http://www.tntware.com/delphicontrols/unicode Unforunately, these are not Bold aware, but try to fill them manually to see if that will work. Regards, Danny Back to top sham Guest Posted: Mon Jun 19, 2006 3:26 pm    Post subject: Re: Unicode for BOLD Hi Danny, I have replaced the TBoldEdit component with a TNTEdit component and at the object space level, the unicode strings seem correct (i.e. assigning unicode string to object property from a TNTEdit component and then showing it in another TNTEdit component). What I found by using by tracing the SQL statements (using an IBSQLMonitor component) is that the sql generated (for the UPDATE statement) does not have the property as the unicode string entered (i.e. AscII characters ??? etc used). In my model editor, the property is wideString and the PMapper name is set to TBoldPMWideString. I have also created the database using the character set ISO_8859_1. Any ideas why the update statement is not using the property as a unicode string? Sham.

Could the above be the reason for the unicode problems? You got me interested so I wrote a test app and both adapters work when configured correctly. I found it neccesary to specify ISO8859_1 as the ServerCharSet in SQLConnection.Params for DBX and lc_ctype=ISO8859_1 in IBDatabase params for IBX. Now, IB/FB apparently store unicode as UTF8, and we are expected to perform conversions, so I had to modify these two methods: TBoldPMWideString.ValueToParam .... Param.AsString := UTF8Encode( aWideString.asWideString ); .... and TBoldPMWideString.ValueFromField .... aWideString.AsWideString := UTF8Decode ( Field.AsString ); .... As for the GUI controls I found the use of TBoldStringFollowerController class to be the problem, as it's used in all Bold aware controls. So to have unicode Bold aware controls one would have to: - make controls inherit from appropriate TNT controls - replace TBoldStringFollowerController with TBoldWideStringFollowerController Regards, Danny Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         BorlandTalk.com Forum Index -> Delphi Model Driven Architecture (General) All times are GMT Page 1 of 1   Jump to: Select a forum C++ Builder Newsgroups----------------C++ BuilderC++ Builder (ActiveX)C++ Builder (Announcements)C++ Builder (Command Line Tools)C++ Builder DatabasesC++ Builder Databases (ADO)C++ Builder Databases (Desktop)C++ Builder Databases (InterBase Express)C++ Builder Databases (Multi-Tier)C++ Builder Databases (SQL Servers)C++ Builder (Graphics)C++ Builder (IDE)C++ Builder (Internet)C++ Builder (Internet Socket)C++ Builder (Internet Web)C++ Builder (Jobs)C++ Builder (Language)C++ Builder (Language C++)C++ Builder (Compatibility with MFC)C++ Builder (Native API)C++ Builder (Non-Technical)C++ Builder (Students)C++ Builder (Third Party Tools)C++ Builder (Upgrade)C++ Builder (VCL)C++ Builder (VCL Components Usage)C++ Builder (VCL Components Development)C++ Builder (VCL Usage)C++ Builder (WinAPI)C++ Builder Installation Delphi Newsgroups----------------Delphi (General)Delphi ActiveX Controls UsageDelphi ActiveX Controls DevelopmentDelphi As400Delphi DatabasesDelphi Databases (ADO)Delphi Databases (dbExpress)Delphi Databases (Desktop)Delphi Databases (InterBase Express)Delphi Databases (Multi-Tier)Delphi Databases (SQL Servers)Delphi DeploymentDelphi GraphicsDelphi IDEDelphi InternationalizationDelphi InternetDelphi Internet Isapi-WebBrokerDelphi Internet WebSnapDelphi Internet WinsockDelphi JobsDelphi Language BASMDelphi Language ObjectPascalDelphi Model Driven Architecture (General)Delphi Model Driven Architecture (Third Party)Delphi MultimediaDelphi Native APIDelphi Non-TechnicalDelphi ObjectPascalDelphi OLE AutomationDelphi OO designDelphi OpenToolsAPIDelphi Reporting-ChartingDelphi RTLDelphi StudentsDelphi TeamSourceDelphi Thirdparty ToolsDelphi Thirdparty Tools (General)Delphi Thirdparty Tools (IntraWeb)Delphi Thirdparty Tools (RaveReports)Delphi UpgradeDelphi VCLDelphi VCL ComponentsDelphi VCL Components UsingDelphi VCL Components WritingDelphi WebServices SOAPDelphi WinAPIDelphi XMLDelphi Installationcomp.lang.pascal.delphi.components.misccomp.lang.pascal.delphi.components.usagecomp.lang.pascal.delphi.components.writingcomp.lang.pascal.delphi.databasescomp.lang.pascal.delphi.misccomp.sources.delphi JBuilder Newsgroups----------------JBuilderJBuilder AnnouncementsJBuilder Applet IssuesJBuilder As400JBuilder CompilerJBuilder CORBA/RMIJBuilder DatabasesJBuilder DB SwingJBuilder DebuggerJBuilder DeploymentJBuilder DocumentationJBuilder EnterpriseJBuilder HandheldJBuilder IDEJBuilder JavaJBuilder JavaAPIJBuilder Java LanguageJBuilder Java SwingJBuilder Java BeansJBuilder Java Beans UsageJBuilder Java Beans DevelopmentJBuilder JBCLJBuilder JDataStoreJBuilder JobsJBuilder LinuxJBuilder MacintoshJBuilder & MobileSetJBuilder MultiLingual AppsJBuilder Non-TechnicalJBuilder OpenToolsJBuilder Servlets (JSP)JBuilder StudentsJBuilder Team DevelopmentJBuilder Thirdparty ToolsJBuilder UpgradeJBuilder Installation InterBase Newsgroups----------------InterBaseInterBase Bug DiscussionInterBase GeneralInterBase IBConsoleInterBase OpenSourceInterBase ReplicationInterBase SQLInterBase ThirdpartyInterBase Installation Miscellaneous Borland Newsgroups----------------AppCenterAppServerEnteraVisiBroker  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
