I'd like to create dialog box with completed fields...
write smth like this

class CDlg:public CDialog{
public:
CDlg(UINT nRes, CWnd *pParent,int nIndx=-1);

DECLARE_MESSAGE_MAP()
afx_msg void OnOk();
};

CDlg::CDlg(UINT nRes, CWnd *pParent, int nIndx) : CDialog(nRes, pParent) {
if(nIndx!=-1){
CPerson* pers=(CPerson*)ob_arr[nIndx];
AfxMessageBox(pers->GetName());//check is there access to CPerson's functions ... it's OK
SetDlgItemText (IDC_EDIT2,_T("1111111")/*pers->GetName()*/);//error in winocc.cpp line:156
}

}

Do the initialization part in OnInitDialog. Do not do this in the construtor.

Use an Init function for these kind of initialization purposes.

Store the nIndx as a member variable or store the person object as a member variable of the dialog class.

I have a newly desinged cam file in which image files are stored in the form of bitmap.This bitmap is retrived & converted in to jpeg image and then it is displayed in the video player.(it is an Active control ).

Everytime to play the video,i call this function,Playwave(int picno).
for displaying this image,i call m_pdib.GetJpegData(1,true) and m_pdib.DispTODC(1,true).

I want to store this jpeg image in a folder.

How to do that.

If you could put the image on a DC or on a CBitmap object you can solve your problem using the class CImage. It has the Save function that automatically convert the image in many file format (jpg gif png bmp).
Hope this helps.

DEFINE_GUID(ImageFormatJPEG, 0xb96b3cae,0x0728,0x11d3,0x9d,0x7b,0x00,0x00,0xf8,0x1e,0xf3,0x2e);
CImage m_Image;
m_Image.Attach(hbitmap handle);
m_Image.Save(yourfile,ImageFormatJPEG);
m_Image.Detach();

I think your problem is write file(jpeg)
But I suggest if you can convert bitmap to jpeg use to write data jpeg to file instead use CImage
