Unicode support for VB for Help

Hi,

I need to develop an application in NT 4.0 Chinese version. The most of Chinese word will have both BIG-5 code and UNICODE code. But some Chinese word only has UNICODE. Those Chinese words that have both BIG-5 code and UNICODE code can display correctly in VB TextBox Control. The others Chinese words that only has UNICODE code can not display correctly in VB TextBox Control. But, we can type this Chinese word in both notepad.exe and Microsoft Word 97 and cannot in wordpad.exe.

When I used VB to build my application, I found that it cannot support UNICODE, too. So it display garbages when I type a chinese word in textbox control.

How can I do? ..... Used VC++ to build a TextBox control to support Unicode for myself? or someone have good idea about UNICODE support for VB.

Thanks a lot.
