PB11 WebForm方式下messagebox的本地化处理

 PB11 在 web form 下毕竟工作方式有很大区别，使用过程中发现很多的对话框窗口已经不再调用操作系统的底层函数来实现了，其中最有影响的当属messagebox函数，虽然屏幕上显示这样的提示：

 

按钮文字是英文的看起来也不是非常难受，但给用户使用时，总感觉美中不足。为次，多次上到sybase newsgroup寻求解决方案，但最后还是否定了从PB版本上的直接解决方法。以下是我从新闻组上交流到的信息（后者前先者后）：

 

Jim O'Neil:

You're going to use a binary editor on a DLL shipped with
PowerBuilder???  I don't even think .NET would let you do that as it
would be a security breach if the assembly were tampered with -
assuming you could even figure out WHAT to change.

DJ posted a quite viable workaround for you, I would recommend that.
In terms of the other 'system dialogs' that are also not
culture-aware, I supposed the job would be bigger/harder.

 

DJ Huang:

No I am not suggesting to change the DLL or implementation internal to PB11.I do ask you to write a modal PB window with OK/Cancel button or othercommand buttons, to mimic MessageBox look-and-feel

DJ Huang:

qland/Jim,If the Engineering team has no quick solution, then you can try this workaround:Create your own POwerBuilder window, type = response window, with a fewbuttons to simulate the messagebox.  Then call your own MessageBox()function.  A meesageBox function in your class will hide the system build-inmessagebox when you call within that class

所以，最后我按DJ Huang的建议，自己使用PB对象来解决了，下图就是新的结果，基本上实现了原来messagebox函数的所有功能，但无法做到后面3个参数的缺省调用。

 

调用方式还是与原来的messagebox函数类似：

calling this function like this：    messageboxx('prompt','information', icontype, buttonname, default)fox example:messageboxx('error?,'aaaa~r~nbbbbbbbb',Exclamation!,AbortRetryIgnore!,2)

》》》》 messageboxx function  There is no heavily overrided messagebox in order to keep the original messagebox function.---------------------------------------------------global type messageboxx from function_objectend typeforward prototypesglobal function integer messageboxx (string as_title, string as_info,icon aic_type, button abt_type, integer ai_default)end prototypesglobal function integer messageboxx (string as_title, string as_info,icon aic_type, button abt_type, integer ai_default);s_messageboxstr_recvinteger li_rtnstr_recv.as_title = as_titlestr_recv.as_info = as_infostr_recv.aic_type = aic_typestr_recv.abt_type = abt_typestr_recv.ai_default = ai_defaultopenwithparm(w_messagebox, str_recv)li_rtn = message.DoubleParmreturn li_rtnend function

越来越喜欢PB11的WebForm了，现正在将原来OA中的某些业务逻辑比较复杂的功能采用PB11实现。
