Try searching on OCR or Optical Character Recognition. I'm sure you will find a lot of work on this subject.

One way to implement OCR is using a Feed-Forward Multilayer Perceptron Network that implements the Backpropagation learning algorithm...

There is a lot of this stuff on the internet, too.

I use the SQLTable to get it, but it didn`t work well. I don`t quite understand the first parameter (hstmt). Any body can help? Got my question?

It's the connection handle to the data source returned by SQLConnect().

Display number on the Push Button

Hai all,

I want to display the number on the Push button. The button already loaded with bitmap. It starts with 0, whenever mouse click occurs on the client area, the counter starts counting and the next number we are going to used(clicked) on the client area should be display on the button.

so far....
I tried by using DrawItem I don't know the proper way to handle the drawitem.

Note:
1.Number to Display on the Button, that already loaded with Bitmap.
2. I tried to use Drawitem.

With regards

use CBitmapButtons

CBitmapButton bezier;

bezier.LoadBitmaps(_T("IMAGE27UP"), _T("IMAGE27DOWN"), _T("IMAGE27DOWN"), _T("IMAGE27GREY"));
bezier.SubclassDlgItem(IDC_BUTTON_BEZIER, this);
bezier.SizeToContent();

then, if you want to change the image just use
bezier.LoadBitmaps(_T("IMAGE29UP"), _T("IMAGE29DOWN"));

Address of member functions

Hi,
Is it possible to obtain beginning & ending addresses of public member functions of C++ object, outside the object? If yes How?

Thanks
Yogesh

If the class has no inheritance or just single inheritance, you can get its starting address:

class A
{
public:
  int func() { return 1; }
};
 
int (A::*ptr_to_method)() = A::func;

ptr_to_method now holds the address of the method. But this address won't always be called if the method can be inlined (as the one above) so every call to A::func() might not go through that address in memory.

As I understand, the function addresses obtained using this way are not the real addresses. They just provide an offset of a member function within an object.

#include <conio.h>
class A
{
public:
int func() { return 1; }
};

void main(){

A x;
int (A::*ptr_to_method)() = A::func;
getch();
}

If for the above program you check inside Watch window of VC++ 6.0, the values of following variables
ptr_to_method
(&x)->func

It shows different addresses. Now which one is the correct address of function "func"?
Also I was not able to capture the value of "(&x)->func" inside program.

That is normal. VC++ will import the bitmap and not show it. You can still use the bitmap resource in the project.

Visual C++ .NET v.2002 and MDI CEditView class..

Hi.

I wonder if anyone can help with a problem that I am having ?.

I want to be able to create an MDI application that simply allows me to create text document(s) that I can edit and save/load.
I have tried using the AppWizard that ships with the above named software version, but it simply does not work.

After building the app. and running it, I create a new doc. and type the words 'hello there' in the 'new' doc. window, save it and reload, and all I get is the first character of the string plus four characters of rubbish.

I have tried to determine what is wrong but to no avail.
In desperation I re-installed a very old copy of VC++.6 and it works fine.

Does anyone know of any changes or prehaps new clauses that need to be added to either the view or document classe(s)?

Best regards.
James
