you have to use Rpcrt4.lib as stated in the Requirements section of the MSDN page.
(Menu Project->Settings, select the Link, add Rpcrt4.lib in the Object/Library modules textbox).

OLEDB + Date [modified]

Hi everyone,

I am using OLEDB APIs (such as CTable, CDynamicAccessor etc) for retrieving data from a text file (say abc.txt).
The problem is while retrieving date value.

When date in "Regional and Language Options in Control Panel" is "M/d/yyyy" format, GetValue of CDynamicAccessor returns correct date value. If i change date format to "d/M/yyyy", GetValue returns NULL.

Can anyone tell me the reason for this behaviour?

Thanks

What format is the date value inside the text file?
The problem recognising D/M/Y versus M/D/Y is that there are a large number of values (where both M and D are <= 12) where it cannot be categorically determined which format is in use.

If the data driver you are using is expecting M/d/yyyy, then in theory you could call SetThreadLocale() while you do the retrieval, and set it back again afterwards, but there's no guarantee that it isn't using LOCALE_SYSTEM_DEFAULT or LOCALE_USER_DEFAULT, rather than calling GetThreadLocale() internally.

Why can't input Arabic?

I am developing a multilingual software. In my software I can changed language to Arabic. So I install a "Arabic" input method. When I tried to input Arabic in one of my CEdit control, the CEdit didn't accept Arabic.

It seems OK, if I type Arabic here.
Arabic: سيبسايبعهصقثعخرتؤمترهقفثتمبتخشهقثهعخ

Is there any special property of CEdit that I need to set? Expect somebody could help me solve this problem.

I think we have a little problem if he creates a font for editbox it will be work but if he runs his program on the a computer that has arabic language for OS so I think he will be problem.

1. Have you enabled this language on your computer at first place? (Internet explorer/FF has it inbuilt)
2. If 1 is done, then is your application Unicode?
3. If 2 is true, then what do you mean by your CEdit control did not accept Arabic?

Anything I will say you will bring it down to whatever you want.

That's it. Now, are you able to type in Arabic language in notepad?

I am asking if you've done an ANSI build or an Unicode build of your application. What happens when you type Arabic in the application that you built? Do you see question marks to appear instead of Arabic?

I can type Arabic in notepad. But I can't type it in my application. When type Arabic, it displays nothing.

Again, does your application understand Unicode? Have you got _MBCS or _UNICODE defined in the preprocessor definition? See here if you don't understand what I am asking you about.

Now it really works. I can input Arabic in CEdit.

But it seems that VC6.0 doesn't support unicode input while coding. I can't input Arabic directly in the code.

Visual Studio.net will support unicode well.

Japanese character

8-Jul-07 20:16

Dear all,

I would like to display japanese character in my editbox, and the no of characters should be 32. that means its not 32 japanese characters. its 32 keyboard strokes. If a user enters 32 keyboard strokes, then the edit box shouldnt display the character which was pressed after 32.
Can anyone please help me on this?

Thanks in advance.

Regards,
Ram

It's been a long time since I did C++, but surely it should be easy to handle the event and maintain a character count? Of course, make sure to _reduce_ the count if the user hits Backspace/Del. Also, you shouldn't increase the count if a non-char key, like Ctrl or the arrow keys was pressed.

Also, pay attention to the paste operation!

Cheers,
Vıkram.

I was trying to catch the character by the onchangeeditbox() function. But if i press a char in keyboard it doesnt come to that function. after i press enter only it will go to that function. thats why i couldnt able to count the no of chars.
