File operation
1, Unicode file start identification: 0xFeff;
#define setUnicode (Pfile) (FPUTWC (0xfeff, Pfile)
2, the text ("") function can convert the code value, not only to the wide character, for example:
Tchar Tzbuf [126];
Char czbuf [126];
Memset (TZBUF, 0, 126 * SIZEOF (TCHAR));
MEMSET (CZBUF, 0, 126);
WSPrintf (TZBUF, Text ("A San ASGA");
Sprintf (CZBUF, "ASGA");
or:
Tchar tzbuf [126] = text ("A San ASGA");
Char czbuf [126] = "A San ASGA";
in conclusion:
Address TZBUF: 963F, 4E09,0061,0073,0067,0061,0000
Address CZBUF: B0, A2, C8, FD, 61, 73, 67, 61, 00
3. Some equipment comes with the text editor unable to identify Chinese characters, whether it is ANSI or Unicode format;
4, when reading and writing Unicode text, you need to use "B" modifiers, such as "RB", "WB", not affected by FGETS and FGETWS;
5. Output format control description:
SINGLE-BYTE Character with Printf Functions H C OR C
SINGLE-BYTE Character with WPrintf Functions H C OR C
Wide Character with Printf Functions L C or C
Wide Character with WPRINTF Functions L C or C
SINGLE-BYTE - Character String with Printf Functions H s OR S
SINGLE-BYTE - Character String with WPrintf Functions H s OR S
Wide-Character String with Printf Functions L s OR S
Wide-Character String with WPrintf Functions L s OR S
Easy error 1:
SSCANF (BUF, Text ("% D"), var); // Forgetting "&"
SSCANF (BUF, Text ("% D"), & var);
Easy error 2:
When the Template

Maybe error. I have encountered errors: MyClass uses Virtualalloc to allocate memory, and the value of SIZEOF (MyClass) is uncertain, resulting in allocating memory failed.
About ComboBox:
ComboBox has two types of DropDown and Droplist. For Droplist, Updatedata () can be used to get the user selected items in OnSelchange (), for Dropdown, you must use m_ctrlcombo.getsel (m_ctrlcombo.getsel) )), Then use Updatedata () to get the item selected. It is necessary to use the SHE handling problem, such as reading the file:
File * pfile = fopen (StrfileName, "R");
DO
{
__TRY
{
FGETS (CZBUF, LINENUM, PFILE);
// Do Your Things Here ...
}
__EXCEPT (Exception_execute_Handler)
{
// Continue or Break?
}
} while (! feof (pfile));
Fclose (pfile);
Use bitmap buffer drawing:
// Define bitmap:
CBITMAP M_BITMAP;
// Load bitmap or initialization bitmap:
// Load bitmap:
m_bitmap.loadbitmap (idb_bitmap1);
/ **** Initialization bit map **********
CClientDC ClientDC (this);
M_bitmap.createcompatibleBitmap (& ClientDC, 32, 32);
// ********************* /
// Initialize the memory device handle:
CClientDC ClientDC (this); // Display device handle
CDC MEMDC;
Memdc.createCompatibleDC (& ClientDC);
// Bit map is loaded into the memory device description table:
MEMDC.SELECTOBJECT (& M_Bitmap);
// Use a memory device to operate a bitmap:
MEMDC.PATBLT (0, 0, 32, 32, whitess); // Brush Wall
Memdc.ellipse (2, 2, 30, 30); //
// Display bitmap: OnDraw (CDC * PDC, ...)
Bitmap BM;
M_bitmap.getObject (Sizeof (BM), & BM);
PDC-> Bitblt

BM.BMWIDTH,
Bm.bmheight,

Srccopy);
// Other bitmap operation functions:
// PATBLT (int X, int y, int NWidth, int NHEIGHT, DWORD DWROP);
// Stretchblt (int X, int y, int nwidth, int nheight, cdc * psredc, int xsrc, int ysrc, int NSRCWIDTH, INT NSRCHEIGHT, DWORD DWROP);
