This is save function that save the structure to the vector:
Please note that I need to save(push) several Face structure in the vector.
that is each time I press the Apply button, I need to push a different set of Face to the vector:
code:--------------------------------------------------------------------------------
void CFeature::saveFeatures (std::vector < Face > & Feat)
{
Feat.push_back(FaceFeat);
return;
}
--------------------------------------------------------------------------------
Then I have a button (Saveft) on my FormView to save the Vector to a file:
code:--------------------------------------------------------------------------------
void CFeature::OnSaveft()
{
CMFFADoc* pDoc = GetDocument();
// Synchronize all other views
pDoc->UpdateAllViews( this );
WriteFaceVector(ftname , Feat);
}
--------------------------------------------------------------------------------
This function write the vector to the file.
I'm taking info (Structure) from a video file(.vid) and save them in a new file with the same name as the video file but with (.fea) ext:
code:--------------------------------------------------------------------------------
bool CFeature::WriteFaceVector( char * ftname , const vector<face> & v)
{
m_FtFileName = VC.m_VidFileName;
//Need to convert file name from CString to Char*
ftname = m_FtFileName.GetBuffer(m_FtFileName.GetLength());
char* pos;
pos = strrchr(ftname,'.');//Find the ext
*(pos+1) = 0;
strcat(ftname,"fea"); //Create new ext
ofstream m_FeatureFile(ftname,ios::binary);
if (!m_FeatureFile) return false;
std::vector<face>::size_type size(v.size());
m_FeatureFile.write(reinterpret_cast<const char*="">(&size), sizeof (std::vector<face>::size_type));
for(std::vector<face>::size_type i =0; i < size; ++i)
{
if(0 != size)
m_FeatureFile.write(reinterpret_cast<const char*="">(&v[i]), size * sizeof (Face));
}
return true;
}

All I can suggest is for you to step through your code AND STL (no matter how nightmarish it is) line by line. You are dereferencing a bad pointer; maybe you didn't allocate something, maybe a destructor is being called; maybe a copy constructor isn't doing what you think it's doing. It could be a myriad of things. (STL itself is likely not at fault, just how it's being used. It may not even be STL.)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

I've an application that use RichEdit. Right now, I want to add a functions that can let users choose different zooming factors like 50%, 100%, 200%, etc. like those work in winword. However, I've no idea how to start. Could any experts help me? Thanks!

change the font and the window size according to the zoom settings
i can't even remember what my point is now, but anyway, i'm correct

Convert long to SYSTEMTIME
long day =24,mm =4,year =1976;
I need to convert day ,month,year to SYSTEMTIME.
How?
|
|
|
|
|
long day =24,mm =4,year =1976;<br />
SYSTEMTIME st;<br />
<br />
ZeroMemory(&st, sizeof(SYSTEMTIME));<br />
st.wYear = (WORD)year;<br />
st.wMonth = (WORD)mm;<br />
st.wDay = (WORD)day;
Best regards, 
Dominik
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do?? 
(doesn't work on NT)

you mean, day,mm,year are stored in one long ?
asume year is stored in high word and day+month in low word:
systime.wDay= (BYTE)lDate; // low byte low word
systime.wMonth= (WORD)(lDate>>8)&0xFF; // hi byte
systime.wYear= (WORD)(lDate>>16)&0xFFFF; //hi word
you may change it depending on
sequence in which values are stored in long

I need to modify a library that is used by a C-Scripting application to allow a MFC application to stop and start the processing.
The DLL builds OK, but both the application which loads the dll and the script that checks the flag always see the flag a false (0).
However I get the abortFlag is always 0 (false); see code snips below:-
First the Modifed section of th DLL project:-
#define DLLDIR __declspec(dllexport) // export DLL information
// The extern "C" declaration allows mixed languages compactability, it prevents
// the C++ compiler from using decorated (modified) names for the functions
extern "C" { <-------- Error here !!!!!!!!!!!
void DLLDIR APPSetAbortFlag(int);
int DLLDIR APPGetAbortFlag(void);
};
static int abortFlag; /* The flag to abort the test */
static int contiuneFlag; /* The flag to schedule the test to continue */
static int enterFlag; /* The flag to schedule data entry the test */
int APPGetAbortFlag()
{
return abortFlag;
}
void APPSetAbortFlag(int a)
{
if(a == 1)
abortFlag = 1;
else
abortFlag = 0;
}
Next the section of code for the application that uses the DLL:-
typedef void (*APPSETABORTFLAG)(int); // Pointer to APPSetAbortFlag(int)
typedef int (*APPGETABORTFLAG)(void); // Pointer to function int APPGetAbortFlag()
hMod = LoadLibrary("WHLLib.dll");
pGetAbortFlag = (APPGETABORTFLAG) GetProcAddress(hMod, "APPGetAbortFlag");
pSetAbortFlag = (APPSETABORTFLAG) GetProcAddress(hMod, "APPSetAbortFlag");
I set the flag like:-
UINT value = 1;
(pSetAbortFlag)(value);
and read the flag like:-
int result = (pGetAbortFlag) ();
Are they a problem with the use of the item of data in the DLL?

I am trying to have an MFC application that shares data with a DLL.
The DLL is loaded via a batch file in a C-Scripting environment.
I have included the following lines of code in both the EXE and DLL
#pragma data_seg(".CSL_DATA")
int volatile abortFlag = 0; /* The flag to abort the test */
int volatile contiuneFlag = 1; /* The flag to schedule the test to continue */
int volatile enterFlag = 0; /* The flag to schedule data entry the test */
#pragma data_seg()
#pragma comment(linker, "/SECTION:.CSL_DATA,RWS")
On the C-Scripting side of things the batch file loads the DLL as follows:-
#loadlibrary 'WHLLIB'
However any changes in the data (abortFlag say) is not reflected in the other side.
Basically all I want is the 3 variables to be visible by the libray and the application.
Am I doing it wrong?!?

hi,
please help me in any way you can which will be highly appreciated.
i'm a computer engineering student and i'm doing a 3 months project on computer controlled musical water fountain. we have to create an audio player and capture the instantaneous frequency of the song playing from its buffer, calculate the dominating frequency for brief interval of time and send it to the electrical team who will receive the signal and activate the corresponding motors for the different pattern of the water fountain.
I used Java's JMF(java media framework) API but it could only give the samples per second. but what i actually need is the sample values.i also studied the DirectX.DirectSound 's getFrequency() method but it could only give the samples per second.
Eagerly hoping for positive response.

Hello, I am a student working on a camera surveillance project and I am trying to write an
application that will be able to use any camera regardless of its vendor.
I have an axis PTZ 2130 camera to work with, and I have the ActiveX control for this camera that displays the MJPEGs being pushed from the camera.
If I want to periodically grab one of those JPEG being pushed from the
camera what would be the best way to do it. I know I want to use DirectShow.
But I'm not quite sure how to go about doing it.
Any help would be much appreciated, thanks.

Download and install the DirectX SDK.
Take a look at the PlayCap sample application which installed to C:/DXSDK/Sample/C++/DirectShow/Capture/Playcap for a default installation. It describes how to get a capture graph up and going. Modify the graph to include a ?sample?grabber filter (the name depends on the version of the SDK). Modify the application to grab and parse jpegs.
There is a fair bit of work involved in doing this, but enough people on Codeproject know how to use DirectShow so you should get plenty of help
If you can keep you head when all about you

If you can think - and not make thoughts you aim;
Yours is the Earth and everything that's in it.
