Hi!
I have a big windows application which doesnt support unicode yet. But in one specific Edit box, i need to correctly process the data that will be entered there, it can be a simple text or a chinese text. How can I correctly process the data without making all the project in UNICODE. Because its too much work for this time to modify all the code to support unicode.
How can the Edit box handles the data and what data type should i save the data for further processing? How can i know if the entered data is chinese (2 bytes) or just a simple text (1 byte)?
Please help.

You can still use wchar_t in a non-Unicode application.

my VC6 project says "can not acssese ClassView infomation file, ClassView information will not be avalable".
which file is "ClassView information" file in VC6?
how to solve the problem?

The .ncb file holds the classview information,
the .clw file holds ClassWizard information.
If the file exists, it is most likely corrupted. Delete it and it will be recreated when you load the workspace again. It is a definite 'issue' to have the file loaded by more than one copy of MSDEV at a time!

How to read from a string
char str[] = "field1 field2 field3 ..."
only one field3 string using sscanf() and one buffer for it - tmp.
sscanf(str,"%s %s %s",0,0,tmp);
it produces exception in this case

Replace zeroes by address of variables because sscanf expects some address to be passed in. You are passing in NULL hence the exception I guess.
char str[] = "15 12 14";
int num1,num2,num3;
num1=num2=num3=0;
sscanf(str, "%d %d %d", &num1, &num2, &num3 );
printf( "Num1: %d, num2: %d, num3: %d", num1, num2, num3 );

I want to use just one variable to its arguments list.
Consider if I need to read 20th field from a string I dont want to declare
int num1,num2,num3,num4, ........... num20
to read last field

sscanf isn't the right function for doing this. And using the %s option for sscanf isn't advised since it will almost never do what you hope it will. In fact, only your first %s will be read in and you will corrupt memory with the other 2 (even after fixing your references to the variables).
If you are looking to access a single (or even a few) elements in a delimited string, write a split method, or use strtok to march through the array to the elements you want to access.

Use:
sscanf(str, "%*s %*s %s", tmp); 9ine wrote: it produces exception in this case
As it should since you are trying to write to address 0.

I did not know sscanf could do that.

I do hope you were being sarcastic :-P
sscanf is great when parsing typed information ... it is not very useful for trying to extract substrings.

Oh, and I noticed 2 typos in your Signature:

Just checking ...
And I've thought about changing it to say "at least 8 hours ... 5 days" since my old job fit the 20 hour/7 day mold.

Oh no. That was normal operating procedure ... When crunch time came around, the managers would pressure us to spend the night in the office ... even over weekends!

Or like this.
N.B. Add error handling as required!
<br />
char str[] = "field1 field2 field3 ..."<br />
<br />
char * cpLastSpace = strrchr(str, (int) ' ');
if(NULL != cpLastSpace) {<br />
sscanf(cpLastSpace+1,"%s",tmp);<br />
}<br />
