ok!
Actually I was taken you the following .
Like right click on -> project properties -> debugging and select command arguments and click <edit>...
when click on this stage we get one dialog which show the Macro button I have select the .exe from there(Insert button) and add set two parameter which I have wrote in the privious reply.
I had talk about the entire walk through. I have set this two parameter but and set break point also but its not reach at the break point.

First, I think your arguments are wrong. You want to pass '-i clock.avi -o clock.wmv' and not '$(TargetExt) -i clock.avi -o clock.wmv' I suppose ?

IS your project compiled in debug mode ? What happens if you put a brekpoint at the very start of your project (e.g. at the top of the main function) ? Are your breakpoints disabled or not ?

Yes. Just set a breakpoint (F9) on any line you want to stop at.

Hi,
I have posted a message on the same project but on a different problem. The task is, to load an image file, preferably of any format, jpg or bmp and calculate the FFT of it and also have the option of running thro' a Bessel filter and reconstruct the filtered image.
The problem is, i am new to VC++ and i started studying this Beginning VC++ from Wrox publications, it is useful but very time consuming. I read thro' the chapters and i think i can go about it as of now.
Now, I am actually confused as to what classes i should create and where to create, the book mentioned many things regarding where to create classes and why, which i couldnt get a grasp off. Can any1 tell me how to go about with this project.
Also, regarding my earlier question, i was asking regarding loading jpeg files for processing because, they are in compressed format, one of the guys suggested using CImage class. Please also point out how to go about using it! 
I dont know if its too much to ask, but atleast direct me as to how to proceed, would be highly grateful. If this task is too much to start for, then pls suggest me what i can do in the beginning to get a grasp of the code.
PS: I already have the code for FFT and Bessel filter written. Its a matter of writing the GUI and joining them. I have experience working in the console environment alone!
thanks a lot,
cedance.

If the need for the class functionality is for only once, then you can create an object of the class as local to the function or loop.
But if you want to make use of the same instance many times or in different places or classes then create an object to the class as member to the window/dialog.
cedance wrote: CImage class. Please also point out how to go about using it
You can use CImage or GDI+ Image/Bitmap Class.
Create an instance of any of the above mentuioned class and Load the bitmap of JPEG image and process the image with your written algo.

It sounds like you are asking how to design an object-oriented solution to your problem - you know how to program in C, but with this C++ stuff - how should you structure your code, what classes you should design. If this is the case, I'd suggest starting with something simple - I suspect that you will be marked on whether it works rather than on the architecture.
I have only a superficial understanding of the jpeg format, but from memory an image is based around many small pixel blocks (8x8 if I recall). If I am correct, then this sounds like a great little class to write, and an image / file would simply consist of a collection of these blocks. Basically the class would store the pixels, be able to compress / uncompress the data, be able to read / write files and be able to input / output a bitmap. If you wrote this class, say PixelBlock, then the matter of reading a file would be creating and reading in an array of PixelBlocks, displaying on the screen you would simply uncompress each one and convert to a bitmap, you could create a complete bitmap from all the smaller ones, and then apply your filtering, etc... If you allow the size of the pixel block to be a parameter, then the image could be a single pixelblock formed from all the component pixel blocks, you could have your filtering as a member function of the PixelBlock class so you could perform it on blocks or sub-blocks of any size, etc...
Have I given you enough idesa?

hmmm... Thanks for the ideas, I will definitely try them out. But, it would be more useful if there are some insights in regard to the current issue, coz this is not graded, i mean i am not taking an exam in this regard. I am asked to program this as a part of my job(HIWI). I have experiences with C and matlab and C++ as u had said, but i am really confused with all the gobbledygooks in this message passing and stuffs associated with MFC in VC++!
thanks a lot,

Sorry, I'm getting a bit confused with your posts, so it seems that your problem is really with windows and MFC. I believe the easiest way into windows is to start with someone's example (i.e. a program that compiles and works) and fiddle with it - learn how to add/change the functionality and understand how it works.
In the help file under CImage there is an example
The SimpleImage sample shows how to use the CImage class to load, display, and save a variety of different image formats, including .bmp, .gif, .jpg, and .png. It shows how CImage can be used to manipulate the image in various ways, and how to extract information about the image. SimpleImage uses the CFileDialog class to present the user with the standard Windows dialog boxes for loading and saving files of various formats. The sample creates a docking toolbar using the CToolBar class. The toolbar displays a set of buttons for resizing the image.
I haven't tried it but it could be a good place to start. Otherwise get one of the other samples or a program from codeproject etc.. and start fiddling!

I tried running the samples, when i try to build them it says "0 succeeded, 0 failed, 1 skipped" and i am not able to run the sample program itself!

My samples come setup for Itanium platform, see if the platform is set to Itanium, if it is change it to Win32 (in the toolbar at the top of visual studio).

I may not have made it clear in my reply, but I tried this sample and I got the same error. I tracked it down, in my case, as being due to the sample coming up with Itanium configuration selected, changing this to Win32 and then all compiles OK and I can run the sample.

B'coz no need for those events for Edit Control. But if you want to process those message, then
1) Derive a custom Edit control class and Handle the WM_KEYUP,WM_KEYDOWN messages
or
2) Override PreTranslateMessage method of your dialog and check for your Edit Control messages

How do I display rows of text?
CString testString;
testString = "Test!";
testString +="\r\n";
testString +="Test Again";
pDc->TextOutA(0,0,testString.GetBuffer(),testString.GetLength());
testString.ReleaseBuffer();
This displays text as
Test!||TestAgain.
And not like
Test!
Test Again
What should I do? Also, when I'm reading text from file, how do I control the newline?

Use GetWindowLong(..) API and check for TVS_CHECKBOXES flag.
Modified...
To set the flag use SetWindowLong(..) API, as below
LONG lStyle = GetWindowLong(treeHandle, GWL_STYLE);
if (! (lStyle & TVS_CHECKBOXES))
{
lStyle |= TVS_CHECKBOXES;
SetWindowLong(treeHandle, GWL_STYLE, lStyle);
}

Could somebody give detail about how to use states and action in listbox control in DrawItem?I don't know how to combine the state and action to get result what I want.I have refered to many examples,but different examples have different combination.Help~~~~

IT_DOER wrote: states and action in listbox control in DrawItem
Action defines the drawing action required. If selection is the action being done then it will be ODA_SELECT, now you need to check whether it's Selection or de-selection.
If it's selection then the state bit will be set to ODS_SELECTED else it will be off.
The same principle is to be followed for the rest of the action items.

Q1:
if(action&ODA_FOCUS)
{
CBrush brush(RGB(255,0,0));
pDC->FrameRect(&rectItem,&brush);
}
I wonder why I do this in DrawItem,when I ran the program and clicked the item which is not the first one,the first item's edge turned red too?
Q2:
What is difference between ODA_FOCUS and ODA_SELECT?
Q3:
As I click an item in a listbox,and then I click another control,does combination of (state & ODS_SELECTED)&& !(action&ODA_FOCUS) correspond to the item I clicked firstly?
