Depending on what binary data you are reading, there should be a "smallest unit" of data that you know about. If you are reading single bytes, then obviously a byte is the smallest unit. Same if you know you are reading words or dwords. If you are reading user-defined structures, then you read 1 structure of X bytes.
With that in mind, you do a read and then check the return value to see if there was data or not. This is assuming, of course, that you know the structure of the binary data you are reading.

Just to clarify things a little. I don't know medical terminology. I assume you want the nail centered in the shaft and inserted at the proper angle relative to the shaft. If so, I think it is a little more complicated than just finding the center at one point. The shaft appears to be curved, so you will have to find several centerpoints in order to construct a curve or spline. Then the nail would be inserted tangent to the curve or spline.
Since the image has high contrast between the bone and the background it shouldn't be two difficult to implement an algorithm that finds the edges. If you search this site or the internet for edge finding algorithm's you should find one fairly easlily.

Hi Gary,
Thanks alot for the reply. Yeah as you told one mid point is not sufficient to find the center line. I will find several midpoints at some ample distance in bone so that when i join all the midpoints i will get a curve or tangent line which is the center of bone.
To find mid point i want some code. As i have already used Sobel and Perwitt method algorthims to find edges of bone.
Please suggest me some code or links to find Center.
Thanks again
Ciao,

I think once you have the edge coordinates it shouldn't be too difficult to develop an algorithm to find a curve that minimizes the distance between the two shaft curves.
I think the bigger problem is how to programmatically determine where the shaft begins and ends. I.E. where the shaft meets the end of the bone.

Hi,
When I convert a Visual C++ 6.0 project to Visual C++ .NET by opening the project using .NET environment, and accepting all VC 7.0 conversion defaults, the resulting project would not compile, and gives this error:
Compiler error C2065: '_mbstowcsz': undeclared identifier.
But this functions compiles ok on VC++ 6.0.
This function has these parameters:
in VC6.0++:
int _mbstowcsz(wchar_t*, const char*, size_t) ;
in VC++.NET:
int _mbstowcsz(wchar_t*, const char*, ULONG) ;
Since VC++6.0 and VC++.NET put this function in different locations, I did change the Properties setting for included path, and make it use Dynamic ATL since in VC++.NET this function is in atlmfc/include. I also change Properties/C/C++/Language/Treat wchar_t as Built-in Type to "No". But nothing works.
Please help.
Thanks.

|
|
|
could it be that it is ATL::_mbstowcsz instead of _mbstowcsz?
|
|
|
|
|
Yes, this works, Thank you 
|
|
|
|
|
The c++ compiler take the two function as different function,because the third parameter is different, modify this parameter type to ULONG and try again,good luck!
I am seeking...
For what?
Why did you ask me for what? I don't know!
|
|
|
|
|
Changing the parameter type to ULONG does not fix the compiler error. But thanks anyway.

I have dialog application. One of the controls is the Internet Explorer instance (CHtmlCtrl).
The problem is, that my dialog keyboard accelerators works fine until the IE has the cofus. How to force IE to send accelerators other than IE's standard accelerators to parent window ?

Hello,
I'm using this:
void CTCCDlg::OnSysCommand(UINT nID, LPARAM lParam)
{
DWORD dwStyle;
if ((nID & 0xFFF0) == SC_RESTORE)
{
nID = SC_MINIMIZE;
}
CDialog::OnSysCommand(nID, lParam);
}
but the window doesn't get minimized.
thank you in advance.

Hi
instead of nID = SC_MINIMIZE; try SendMessage(WM_SYSCOMMAND, SC_MINIMIZE, 0, 0);
hope this helps

WM_ACTIVATE can also be used.
The handler gets the new window and the old one.

How can I query "my own" DLL version (i.e. the version a DLL which is loaded into the current process, and where the code to query the version is implemented in=
I have a horribly complex (and ugly) class that does this for any DLL, I wonder if there's an easier way for a DLL that is loaded.
TIA

1) Using the GetFileVersionInfo Win32 API, refer to MSDN for usage;
-OR-
2) Add a export function,say GetVersionNember,into your DLL for query its version number by its customer(client),the following is a simple example,
const WORD LOW_VER_NUM = 0;<br />
const WORD HIGH_VER_NUM = 1;<br />
DWORD GetVersionNumber()<br />
{<br />
return MAKELONG(LOW_VER_NUM,HIGH_VER_NUM);<br />
}
Hope this helps!;P

How to get the height of line in CEdit when there are lots of text with different fonts.

When I use LoadBarState to load state of my toolbar it is shifted by 4 pixels from the frame.
So it is impossible to save toolbar X and Y position less than 4.
To reproduce this bahaviour:
1. create empty MFC SDI project
2. add LoadBarState("barState"); at the end of CMainFrame::OnCreate
3. add WM_CLOSE handler to CMainFrame
4. Add SaveBarState("barState"); at the beginning of CMainFrame::OnClose
Run the app, close it, then tun again -> toolbar is shifted
