I hope to understand your problem right.
Let's suppose your "Object" is a square, if you want to move it from A to B as "animation" with different speeds... One way to do could be:
1) You calculate the differences in coordinates between A and B. Let's suppose an horizontal line where A is (0, 150) and B (500, 150). So for that example the distance is going to be 500 "pixels" or units of your screen coordinates.
2) You set your different speeds. Let's suppose 10 pixels / sec, 50 pixels / sec and 100 pixels / sec
3) Speed = distance / time == distance = speed * time == time = distance / speed Let's choose this last one, time depending on the other 2.
4) You make a function to increment in one pixel the coordinate of your square
void MoveSquare () { square.x = square.x + 1; }
for such a line you don't need a function, but if you want to do more things or move it in more directions you can ride better with it.
5) When you have to move the square you just need to calculate the time needed with the end_pos and the speed (500 / 10 = 50 sec; 500 / 50 = 10 secs; 500 / 100 = 5 sec)
6) You have to call the MoveSquare 500 times to move it till end_pos, then
1st case -> 50 sec / 500 calls = 0.1 sec / call
2nd case -> 10 sec / 500 calls = 0.05 sec / call
3rd case -> 5 sec / 500 calls = 0.01 sec / call
7) Create a timer with that refresh rates 100, 50, 10 ms and call MoveSquare into it
8) when end_pos is reached, kill the timer
Is something like that what you were searching?
Regards.

Hi All,
I am developing an application to Windows Mobile Using VS 2005. And the OS is Windows XP.
I have developed a new dialpad with buttons. As a dialpad it works fine.
But for this I need to load an image. Using CBitmapButton i can load only BMP images. This image changes according to the Skin of the mobile.
When I googled I got the Answer as
SetBitmap API. But to my badluck that is not available for CButton.
Along with this, is it possible to write text on a loaded image?
So can someone help regarding this.
If it is Code then it will be more helpful.
Thanks in advance.

Hello
Thanks for quick response.
Before posting here I have tried SetBitmap() or SendMessage() Functions. In the link you mentioned it is once again telling the same.
Use SetBitmap(). So this wont solves my problem
Thanks.

I was simply responding to your "SetBitmap is not available for CButton" statement.
Have you looked at the CImage class? It can handle other graphic formats in addition to BMP.

Hi...
Is this is correct way of using CImage & its functions?
Because using this also I was not able to load image.
HBITMAP hBitmap = NULL;
hBitmap = SHLoadImageFile(TEXT("windows\\dlrbtn_up_land.gif"));
CRect tr;
m_btnSeven.GetClientRect(&tr);
HDC hdc;
hdc = ::GetDC(m_hWnd);
CImage cImage;
cImage.Attach(hBitmap);
cImage.Draw(hdc,tr);

Are you passing the CString for type REG_DWORD.
I think it should be
DWORD dwValue;
RegSetValueEx ( childkey, (LPCTSTR)name, 0, REG_DWORD, (const BYTE*) &dwValue, sizeof(DWORD));
check this for information Registry Operations[^]

You've told RegSetValueEx() to expect a DWORD value, yet what you are passing is not. Try:
char *stop;
DWORD dwValue = strtoul(data, &stop, 10);
RegSetValueEx(childkey, name, 0, REG_DWORD, (const BYTE *) &dwValue, sizeof(DWORD));

Hi
In my apllication vc++ 6.0 i have 2 thread’s running ThraedA and ThreadB.
In ThreadB some process is keep going.
In ThreadA ,there is a button on clicking, it should send a message to ThreadB(which is busy on doing some other task).
Now my query is this, when ThreadA send a message to ThreadB ,ThreadB should immediately display the Received Message . how to do this ?
regards
shakumar

Normally, a thread can't receive a message if it is a working thread. If it is a UI thread, then it can have a message loop and extract messages from its queue. Of course, it can only retrieve messages when it tries to do so and if it is busy doing something else, then you can't extract the message.
Typically, it is not really done this way: you set a flag (e.g. a boolean) in one thread which can be checked in the second thread.
What are you trying to do in fact ? Some context could be usefull to help you.

thanks for reply
As I mentioned above it is an UI Thread only.
My query is , I able to post a message to ThreadB , from ThraedA.
When ThreadB was free it receive the message and displayed it.
When ThreadB was doing some process ,it is not displaying the received message .
After completing the ThreadB process only it display this received message.
I want ThreadB to display the Message immediately, when message was posted from ThreadA.

As I explained in my previous post, this is not possible unless, you pump your message loop. This is done for example when you give back control to the MFC lib (when your function exits). It's still one thread so when you are busy in your function, nothing else will be processed for that thread.
Ok, but I also asked you a question: what are you trying to do exactly ? Give some context, it might help. What are you doing in that function that takes so much time ?
Anyway, it is also not a good idea to have lenghty function call in a UI thread, because your UI will be freezed during that time.

As Cedric said, you need to pump your messages, while you are busy doing something else. This means you need to add a message loop to your class , and call the loop several times while you are through a long process, to let all the awaiting messages come up.
Something like
MSG msg;
while (PeekMessage(&msg ...))
{
TranslateMessage(&msg);
DispatchMessage(msg);
}
Its never over !

How (e.g., message box, console, debug window)?

Hi,
I wrote one dialog application. For that dialog i have disabled Maximize button. In the context menu also it disabled the maximize button. But my problem is in task manager if i right click on my exe it is showing maximize option and it is maximizing the screen. How to disable this?

You can't do anything about that as your application can still be maximized by using ShowWindow() with SW_MAXIMIZE.

You could try responding to the WM_SIZE/SIZE_MAXIMIZED message with a 0. You could also remove the WS_MAXIMIZEBOX style from the dialog template.
