Unicode chars insertion into Oracle lite

hi guys

i m writing a VB.NET app using the Oracle Lite database as the data source.
Got a problem with inserting unicode chars e.g. chinese into the database
when using the dataadapter and dataset insert command. It gave a
NullReferenceEx ception.

Followings are what i suspect might be causing the problem:
1. olbdbadapter of oracle for .net not able to support unicode
2. oracle lite db not able to support unicode - i have directly inserted
chinese chars into the tables so seems like this is not the cause
3. charset not set for database when creation - i created one with a certain
charset but still failed
4. charset not set for the connectionstrin g to the database - i indicated in
my connectionstrin g but still failed
5. charset not set for vb application

I am at a loss now. Anyone encountered this before and solution for it?

pls help
Thanks

I have a file which has no BOM and contains mostly single byte chars. There are numerous double byte chars (Japanese) which appear throughout. I need to take the resulting Unicode and store it in a DB and display it onscreen. No matter which way I open the file, convert it to Unicode/leave it as is or what ever, I see all single bytes ok, but double bytes become 2 seperate single bytes. Surely there is an easy way to convert these mixed...

I have not been able to find a simple, straight forward Unicode to ASCII string conversion function in VB.Net. Is that because such a function does not exists or do I overlook it? I found Encoding.Convert, but that needs byte arrays. Thanks, /Ger

Also unicode strings should be displayed as nice as possible at the console with normal print-s to stdout (on varying platforms, different

Hello, I'm writing an class library that I imagine people from different countries might be interested in using, so I'm considering what needs to be provided to support foreign languages, including asian languages (chinese, japanese, korean, etc). First of all, strings will be passed to my class methods, some of which based on the language (and on the encoding) might contain characters that require more that a single byte.

This may look like a silly question to someone, but the more I try to understand Unicode the more lost I feel. To say that I am not a beginner C++ programmer, only had no need to delve into character encoding intricacies before. In c/c++, the unicode characters are introduced by the means of wchar_t type. Based on the presence of _UNICODE definition C functions are macro'd to either the normal version or the one prefixed with w. Because...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
