Extracting Chinese Character from a CString

Dear all


CString aStr="Learning ¤¤¤å"; //a mixed English and Chinese string

Extracting each Chinese Character from The String and assign it to a UINT data type.

UINT aWord = ????

i use _MBCS not unicode

can someone tell me how?

For Big5 Chinese Character (2-byte char), the first byte is within a range (about 0xA1 to 0xFE). If it is in the range, then you have to extract both the current and next byte. Therefore, you combine the 2 extracted bytes to form back a Chinese Character.

Thanks for your reply.

for extracting currenct byte, do you mean to use the IsDBCSLeadByte()?

I really donot how to extract both the current and next byte, and combine the 2 extracted bytes to form back a Chinese Character?

I hope the following code can help.

Code:

---

CString aStr = "Learning ¤¤¤å";
char cChinese[3];
cChinese[2] = '\0';
int i = 0;
while (i<aStr.GetLength()) {
        if ((byte)aStr[i] >= 0xA1 && (byte)aStr[i] <=0xFE) {
                cChinese[0] = aStr[i];
                cChinese[1] = aStr[i+1];
                AfxMessageBox(cChinese);
                ++i;
        }
        ++i;
}

Thanks

cChinese[1] = aStr[i+1];
AfxMessageBox(cChinese);

UINT aWord = cChinese // How to assign a Char to UINT

++i;
}
++i;
}

Actually a UINT is a 4-byte variable while a Chinese Character is 2-byte. So how do you want to assign to the UINT?

HI

DWORD GetGlyphOutline(
HDC hdc, // handle to device context
UINT uChar, // character to query
UINT uFormat, // format of data to return
LPGLYPHMETRICS lpgm, // pointer to structure for metrics
DWORD cbBuffer, // size of buffer for data
LPVOID lpvBuffer, // pointer to buffer for data
CONST MAT2 *lpmat2 // pointer to transformation matrix structure
);

I use GetGlyphOutline function to retrieve the outline for a character in the True type font, so it need to use "UINT".

It works ok when I assign a single Chinese Character to UINT.

UINT aWord ='¤¤'; // works ok

But for my program, the user will input a String; therefore, i have to extracte each character from the String and run GetGlyphOutline function for each character to get its outline.

Code:

---

CString aStr = "Learning ¤¤¤å";
int i = 0;
while (i<aStr.GetLength()) {
        if ((byte)aStr[i] >= 0xA1 && (byte)aStr[i] <=0xFE) {
                UINT aWord = 0;
                ((char*)&aWord)[0] = aStr[i+1];
                ((char*)&aWord)[1] = aStr[i];
                ++i;
        }
        ++i;
}

I am really thank you for help me to solve this problem. and i found another way to assign a Chinese Character to UINT

Code:

---

CString aStr = "Learning ¤¤¤å";
int i = 0;
while (i<aStr.GetLength()) {
        if ((byte)aStr[i] >= 0xA1 && (byte)aStr[i] <=0xFE) {
                        int k1=(byte)aStr [i];
                int k2=(byte)aStr [i+1];
                UINT aWord=(k1*256)+k2; //(HiByte * 256 + LoByte)               
                    ++i;
        }
        ++i;
}

What do you think about this method?

Either yours and mine can solve the problem. :-)
In my opinion, yours is better.
