It worked! The problem I was getting was in my "own" Create function - I needed to initialize a couple of "its own" member variables.

So I passed in the parent window pointer (CPropertySheet), created my CListCtrl and tying the parent window back to the property sheet itself - it worked, sort of!

When I tied it directly to the property sheet, the CListCtrl got tangled up in the tabs of the current page and other tabs - i didn't have control over it and moving it didnt help.

So I tried what you suggested, I used SetParent() to change the parent of the dynamic CListCtrl to the current page. It worked great and just how I wanted it - moving the entire dialog had no side effects, I had full control of my CListCtrl.

Thanks so much! Now if someone asks me how, I know how to guide them too - whoo hoo!

what do u mean by that ? can u give me an example or post links to tutorials

Basically im following a book in which we are developing a sketcher application so for that I need to get the enclosing rectangle for circle then with which I will draw the circle by getting the points from the mouse message handlers and providing it to the function which draws circles

NOTE: this is not an exercise, the book explains how to do that but im unable to understand it. I also have the code how to do it, but i wanna understand it. so I'm not cheating thx.

It seems like you need to get rectangular coordinates that are used draw the circle using corresponding API.

If so, you need to get the first point (left,top) when the mouse button is down and get the last point (bottom, right) when the mouse button is released. Have a look at WM_LBUTTONDOWN and WM_LBUTTONUP messages, and if needed, WM_MOUSEMOVE... You can map them to OnLButtonDown, OnLButtonUp, etc., if you are using MFC.

I believe there will be sample codes in CP itself ( I didn't search yet... Wink | ;)

Oh, for the love of god! This makes finger-painting look like a fine-art.....

int radius;
POINT circleCenter;
RECT boundingRect;

  boundingRect.left = circleCenter.x - radius;
  boundingRect.top  = circleCenter.y - radius;

 boundingRect.right = circleCenter.x + radius;
boundingRect.bottom = circleCenter.y + radius;

.rc file in visual studio 2008 express edition

Hi, I could not add a new .rc file to visual studio 2008 express edition, so I created a text .rc file and then added it using add existing item. That part worked okay. The resource folder now shows in visual studio 2008. BUT when I try to add files to the folder it tells me that the express version of the visual studio does not support resource file editing. Please help. How do I edit the resource file? Is there a way that I can create the resource script and it's files outside of the IDE? Please help! Smile | :)

Notepad! It's what I used to when programming windows 3 software...

You get an appreciation of the resources very quickly!

Or pay money for the grown up version... How much do you value your time?

You may open the resource script as a text file inside the Visual Studio IDE. It is not difficult to edit it this way and you'll gain some insight.

Another option Roll eyes | :rolleyes:

Use C# Express Edition to build up, visually, your GUI.
Develop a C# program, exploiting the generated GUI (that is the C# code) to generate the corrensponding C++ resource script.
Write an article about, and post it at CodeProject.

Converting PCM to GSM06.10 with ACM

Hi @ all,

i´m recording speech with the capturBuffer of DirectSound.
Now I want to encode this in PCM recorded stream to a GSM Stream.
It is possible to do it with MS ACM?

Take samples from the DirectSound buffer and run them through ACM to
convert them to a GSM stream.

I would start here:

Audio Compression Manager[^]

These will be the most important functions you'll need:

acmStreamOpen()
acmStreamSize()
acmStreamPrepareHeader()
acmStreamConvert()
acmStreamUnprepareHeader()
acmStreamClose()

Definitely!

I've got a full working implementation using DirectSound for capture
and ACM for compression/decompression.

The GSM codec was the only built-in-to-Windows codec with a small enough granularity ("packet size")
for use with low latency real-time voice communication.

It works well, although I now use a different codec that's NOT implemented as an
ACM codec so the code is sitting dormant. Smile | :)
