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.

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

Thanks for ur reply

Already I display the image using

m_pdib.GetJpgData(1,true);
m_pdib.DispTODC(1,true);

1 is nothing but jpeg image1.similarly if i put 2 means i get second image.

So can't i able to store this image in a file by adding few lines instead of using a new class.

Size of a Resource

Hi,

Is there a function for determining the size in bytes of an embedded resource?

My program needs to use LoadResource to load resources on the fly, and it would really help if it could tell the size of the resource it has loaded.

Thanks,
Rich

You can perhaps find the file format by googling (I didn't find it on http://www.wotsit.org[^])

Hi,

I am asking the file structure for reading .PST files. Becuase I have to open .PST files using File Handling in VC++ in binary mode, and I have to read the messages and display on the correcsponding Rich Edit Control. If you know the structure of .PST file, that helps alot to me. Because structure contains the size of each column like sender name, receivers name, message and so on.
