Hi,
I am using VC++ 6.0. I need to create an XML which has multibyte support and has the Major version and minor version in it.

CComPtr pXMLDomDocPtr;
CComPtr pDataNode;
CComPtr pRootNode = NULL;
CComPtr pNodeList = NULL;
CComBSTR bstrName,bstrNodeName;
CoInitialize(NULL);
VARIANT_BOOL isSuccessful = VARIANT_FALSE;

HRESULT hr = pXMLDomDocPtr.CoCreateInstance( L"Microsoft.XMLDOM" );
if( hr == S_OK )
{
pXMLDomDocPtr->put_async( VARIANT_FALSE );
CString csXMLFileName(newpath);
csXMLFileName += "\\ITCSettings.xml";
pXMLDomDocPtr->put_async( VARIANT_FALSE );
hr = pXMLDomDocPtr->load((_variant_t)csXMLFileName);
}

I have created XML with above code. What do i need to modify in above code to have major and minor versions and with multibyte support

Thanks,

Are you handling WM_ERASEBKGND message in your dialog? If yes, check the implementation. Improper implementation could cause the symptoms that you said.

Hi All,

I'm savitri here. I'm doing FingerPrint project. In this project i want to store fingerprint in database and retrieve that fingerprint for comparision.I created one table called "Images" with 2 fields called ID(AutoNumber)and Image(OLE Object). While inserting fingerprint i'm writing SQL statement like this.
BYTE* buffer=new BYTE[1632];
buffer=m_RegTemplate.pbData;//m_RegTemplate is DATA_BLOB Type.
"INSERT INTO Images(Image) VALUES('"+buffer+"')";

I'm not getting how to retrieve the fingerprint from the database table. i want to save that retrieved fingerprint into m_RegTemplate.pbData for comparision.
Please tell me how to solve this problem and Give me some hints.

Thanks in Advance

Regards,
Savitri P Cry | :((

I don't have any idea in depth, but I've seem my mates working on similar assignments. People actually use "Hashing" on image files. They create hash values for images and store it along with the image files in DB. When you want to compare a new file, they don't read the images from DB and compare with the new file, the create create a hash value for the new file and compare against the hash values in the database..

How do I detect any mouse/key input at application level

How do I detect any mouse/key input at application level. I have an MDI application where processing of mouse/key events are handled in view/doc class of the child window.

I need to check if any mouse/key input didn't occured for a specific time period. I want to handle them in application or MDI so that I can only in one place. But I am getting only WM_MOUSEACTIVATE, WM_SETCURSOR messages in MDI level.

Please help with any suggestion/idea.

Thanks in advance

Install a mouse hook locally in your application using SetWindowsHookEx.
Start a timer that increments a variable.
Whenever a mouse message occurs the hook procedure will be called.
In the hook procedure reset the variable to 0.

Do the same for keyboard with a keyboard hook.

GetLastInputInfo[^] is useful to detect input idle time.

For that u need to user TIMER, on Application startup u need to start it, and if any MOUSE/key input occurred, then u need to again restart the timer. Smile | :)

The value which you have given 131, if it is in Decimal format, the HEX equivalent of that is 0x0083, and its stands for WM_NCCALCSIZE message.

But that's for Winuser.h .. You should know on what context you are searching that number and search in the corresponding .h file.
