Dear all:
I get touch data by used HID.dll, it is raw data.
I wanna process the raw data, before send it to OS.
How can I send touch to OS, using postmessage or sendmessage?

Thank for your help, Victor.

Hello All, Could you help me speed up a program? It's designed to find the square root of a number.
<pre lang="c++">
#include<iostream>
using namespace std;
int main()
{
float a;
float c;
cout << "Square root calculator!" << endl;
cout << "Enter the number you want to square root" << endl;
cin >> a;
cout << "Enter an educated guess" << endl;
cin >> c;
cout << "The squareroot of " << a << " is: " << endl;
do
c = (c + (a/c))/2;
while ( c != a/c );
{ cout << c << endl;
}
return 0;
}
</pre>
My problem is that it get remarkably slow around 55ish. Any advice it appreciated

I'm guessing your issue is the while(). Comparing two floats can be tricky.
while ( c != a/c );
this[^] link may help.

That is the problem with the Babylonian method you have used.
Paul Hsieh has a very good webpage on everything about square roots but were afraid to ask.

It includes details most of the techniques from the standard C library, to the faster integers version that NVidia and Quake use.

hi..i have a requirement to write C/c++ application that converts Microsoft Word
(.doc) Documents into XML format. The application should be able to receive/open a Word document and save a XMl file with the same
name, but with the extension .xml..ur valuable suggestions will help me n will be appreciated..thanks
|

|
|
|
|
is there any library file to include in the code?..how to convert the entire docx formate?
|

You need to follow some of those links and do some research. As I said, reading Word documents in C/C++ is not particularly easy, unless you are familiar with C++/CLI, in which case you can use the Microsoft.Office.Interop.Word Namespace[^]

Store what? A word document is just like a book, lots of words separated by punctuation characters. In order to store that as XML you will need to design a set of rules and tags to split the data into logical sets. Each set would probably need some attrinutes, such as font (character set, height, fixed or true-type, bold, italic etc.). Writing the final XML is just a question of using one of the XML libraries available, either Microsoft or third-party.

I already gave you a link to the Word Interop. You should be able to search MSDN for yourself to find other pages of interest.

I'm thinking the easiest way would be to use Office Automation.

why do we use %u while outputting addresses????
|
|
|
|
|
I would say that %p is preferred. Maybe this[^] link will help.
|
|
|
|
|
%u is not a good choice for outputting memory addresses.
Personally, I use %p or %x for memory addresses.
Look here for printf type fields - printf Type Field Characters[^]

As shown below, there are a few functions in CButton, but i want to change its behaviour by dealing with
virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct) . Yes, just this one and only one functon. It would generate more code than expected if I derive a class from CButton. I wonder if it possible to process this function without Subclass, and not use derivation. If so, how?
Remarks: I must use MFC, it's so hard to use pure Win32 API.
class CButton : public CWnd
{
DECLARE_DYNAMIC(CButton)
public:
CButton();
virtual BOOL Create(LPCTSTR lpszCaption, DWORD dwStyle,
const RECT& rect, CWnd* pParentWnd, UINT nID);
UINT GetState() const;
void SetState(BOOL bHighlight);
int GetCheck() const;
void SetCheck(int nCheck);
UINT GetButtonStyle() const;
void SetButtonStyle(UINT nStyle, BOOL bRedraw = TRUE);
HICON SetIcon(HICON hIcon);
HICON GetIcon() const;
HBITMAP SetBitmap(HBITMAP hBitmap);
HBITMAP GetBitmap() const;
HCURSOR SetCursor(HCURSOR hCursor);
HCURSOR GetCursor();

BOOL SetSplitGlyph(_In_ TCHAR chGlyph);
BOOL SetDropDownState(_In_ BOOL fDropDown);
HICON SetShield(_In_ BOOL fElevationRequired);
#endif // ( _WIN32_WINNT >= 0x600 ) && defined(UNICODE)
virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);

What does that have to do with drawing a CButton? Hooks are system wide so you would need to capture every drawing message and then decide whether it was for your control or not. That's like using a big hammer to crack a small nut.

Inheritance is the natural way for doing that. Any other way (if feasible) would be contrived.
