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

You posted your question only 1 hour ago. This is a forum, not a chat. If you can't wait, then go on rentacoder and pay somebody to do the job for you.

what format is your image? If you're storing a bitmap file, you have to first insert the correct header information & then the raw data (i forget how many bytes the header is, but it's more than a few)
Might check out "serializable" interfaces too

Hi All,
It is fingerprint template. I'm using DATA_BLOB Data type to store the image from the device.I'm not getting how to retrieve the stored image from the database. When i'm trying to retrieve the image from record set.that format is recset.GetFieldValue("Image",buffer);//buffer is of CDBVariant type.I want to assign the buffer value to another BYTE* variable. But i'm not getting how to do this? So please give me any hints to solve this problem. I'm also searching the solution and trying for all the options.
Thanks in Advance.
Regards,
Savitri.

Hi,
I am using a message box API as :
MessageBox(NULL, bstrMessage, bstrTitle, MB_OK | MB_HELP | MB_ICONEXCLAMATION);
This work fine in english...
But in italian OS it is displaying "?" in the caption of "Help" button.
How do we change it to display a correct string in place of "?".?
|

Odd as it may seem, for Italian Windows the translation of "Help" or "&Help" is "?" or "&?". You would have to hack the system DLLs (user32.dll actually) to change it.

Hi Mik,
Want to see the implementation part details.

Sorry, I don't what you mean.
Once again - you can't change the translation ("?") of this MessageBox button.
|
|

|

I want to implement the changes by using redirecting user32.dll to execute our needfull functioanlity..
Mean want to display correct text string of translated "Help" in Italian language.
Could you please tell me the detailed implementation, How I can implpemet through code..... By hacking Systems dll for our need ?

It might be illegal to modifiy Windows system DLLs so I won't tell you how to do it.

...and I really don't care that you're downvoting me for this...

  . That looks funny when they immediately respond with a 1 vote.

Technically speaking, "?" is a string. 
BTW: You may roll your own version of the message box.

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,

Hi to All,
I have a MFC Dialog based application. I just created the application, and did some modification. But I am not able to view the dialog properly, means the dialog appears partially....some parts are visible and others are not...But If i move my mouse cursor to say on a button it appears fine, Also if i click it works fine....just that some display problem...I redo the modification back to original, still the same....
Could anyone p[lease tell me what could be the problem..
Thanks in advance
I am a beginner

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

Jijo.

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..
