_Commandptr m_pCommand;
_Recordptr pRs;
m_pCommand.CreateInstance(__uuidof(Command));
m_pCommand->ActiveConnection = m_pConnection;
m_pCommand->CommandText = "insert into wcs values('uu',6,8,7,6,8,'hi')";
pRs.CreateInstance(__uuidof(Recordset));

query is written in a try block(dont ask me 2 write it elsewhere!)..throws an exception..
|
|
|
|
|
I think the exception is due to some problem in the Insert command.verify it once.

As we know, when we want to shut our computer,
the system pop up a shuting window,
and the screen is locked, that the color lightness is gradually decreased , and the mouse click is invalid.
following is some codes to create this function, and I don't know why it be this way?
////////////////////////////////////////////////////////
byte pbit[16]=
{
0x55, 0, 0xaa, 0x0,
0x55, 0, 0xaa, 0x0,
0x55, 0, 0xaa, 0x0,
0x55, 0, 0xaa, 0x0,
};
HBITMAP hbm=CreateBitmap(8, 8, 1, 1, pbit);
HBRUSH hbr=CreatePatternBrush(hbm);
HDC pdc=::GetDC(0);
SelectObject(pdc, hbr);
PatBlt(pdc, 0, 0,
GetSystemMetrics(SM_CXSCREEN),
GetSystemMetrics(SM_CYSCREEN),
0xa000c9 //BLACKNESS//DSTINVERT//PATINVERT
);
DeleteObject(hbm);
::ReleaseDC(0, pdc);
//end
1.When I move the window (this cwnd) the screen changed, but the WINDOWSXP doesn't do it , how I do it , on the other hand , how to mask the message that not sent to the current shuting CWnd?
2.Byte Array pBit , what its function?And what 0xa000c9 is ?
If you had some good codes about this , please give me for some references, thank you!
Online waiting for answers!
Just my interest for these common things

I'm working on an app that needs to work with both ascii and unicode, but I seem to have run into a rather frustrating problem.
It seems that for some reason, whenever I pass a unicode string to COleVariant.SetString(), the bstrVal only contains the unicode string up to the first NULL character in the string(regardless of the VARTYPE parameter). Hence most of the unicode strings are prematurely truncated. If I remember my unicode correctly it requires a double NULL to indicate the end of a unicode string does it not?
Anybody know of why this may be and how I can fix it?
When I die I'd like to go peacefully in my sleep like my father, not screaming in terror like his passengers!!!

While a BSTR can technically contain any data at all, it's most often used to hold a C-style (zero-terminated) UTF-16 string. Many BSTR wrappers also make the same assumption. Step into the COleVariant code and see if it is doing this.

If no other solution, you can use an alternative approach, based on STL strings: std::wstring for Unicode or std::string for ANSI. This kind of strings allows null character within the string.
For instance:
std::wstring s = L"abc";
s += L'\0';
s += L"def";
size_t length = s.length();
wchar_t c;
c = s[2];
c = s[3];
c = s[4];
const wchar_t * p = s.c_str();
Next, if you need this as OLE variant, I think you can use "safe arrays" for this. For instance, this fragment copies the above string to a safe array:
CComSafeArray< USHORT > sa;
sa.Add(s.length() + 1, (USHORT*)p);
Hope it helps.

Thanks for the suggestions. I managed to fix(hack) it. I was already using safe arrays as the task I'm performing must communicate with older COM and OLE objects. The problem seemed to be an error in one of the OLE cpp files in the MSVS directory. It seemed to call a standard strlen function regardless of the input type so I've changed the code to check for unicode and call wcslen if needed.

In my view, you should just uninstall visual studio or visual c++ what ever you have installed and reinstall it.
It would take not more then 30 min. Do it and then tell us if problem remains.
Wishing you best of luck...
