I have an MFC dll which has no gui, and I dont see a Resource tab in the development environment on which I could drag a CProgressCtrl. I want to launch a progressbar from this dll, and don't really want to do message loops and such which I would need if I used CreateWindow(). Appreciate your input,
sb

Ugly idea, but what if you create the progress bar and then call the window method with WM_PAINT to get it drawn when you need it? No idea how that would behave...

From within the dll, I did this
myCtrl = new CProgressCtrl();
myCtrl->Create(WS_CHILD|WS_VISIBLE|PBS_SMOOTH, CRect(10,10,200,30),
(CWnd*)this, 100);
where the last parameter (100) is just a number I picked out of thin air. I don't know what I should put there.
So when I ran the project that calls this dll, it ran, but no progress bar showed up...
???

What is "this"? You need a valid window where you specified "this", where do you want your progress bar to appear? I think you could be better off with making a message loop...it's not that complicated really.

There aren't any CDialog type windows, and 'this' is just some abstract class where I have the time-stepping loop.
Another thing I tried:
Even though it's a dll, I tried adding a form to it, and dragged a progressbar on it, but then didn't quite know how to invoke this form from my abstract class.
I'll look up the message loop idea. Thanks for the input.

Hello
I have a C++ class with few attributes and functions. Whenever a new value is assigned to a particular attribute (say the attribute is an integer variable in the class) a function should get called (triggered) and the piece of code inside the function should get executed.
Is it possible? If yes, what is the mechanism. Please let me know.
Thanx

Can't you make the member as private/protected and provide a Set method?
Then inside Set method once variable is updated you can call the respective function..
Does it make sense..I hope it helps.

Thanx Sandeep
Simple and effective solution

Alternatively you could make wrapper classes for the members which on their = operator would call whatever is needed to be called.

Hi,
I want to hide a file.So,I used the following code to hide it.
SetFileAttributes (str,FILE_ATTRIBUTE_HIDDEN);
SHChangeNotify(SHCNE_ATTRIBUTES,SHCNF_FLUSH|SHCNF_IDLIST|SHCNF_PATH
,str,NULL);
Where str is the path to file.It is not hiding completely.It looks as blurr untill i refresh that particular folder maunually.How can i solve this problem.

What does SetFileAttributes() return? If 0, have you called GetLastError()?

I'm trying to to make PART of a window transparent AND click-through.
I'm using the following code to show/hide the form (actually making it fully transparent/opaque):
SetWindowLongPtr(hWnd, GWL_EXSTYLE, GetWindowLong(hWnd, GWL_EXSTYLE) | WS_EX_LAYERED);
//Hide the whole form
SetLayeredWindowAttributes(hWnd, COLOR_KEY, 0, LWA_COLORKEY | LWA_ALPHA);
//Show the form
SetLayeredWindowAttributes(hWnd, COLOR_KEY, 255, LWA_COLORKEY | LWA_ALPHA);
This works fine, However:
I also have part of the window colored in COLOR_KEY. This code makes this part transparent but not click-through.
My question is: how do I make this part of the window (again, colored in COLOR_KEY) transparent AND click-through?
Note that I don't want the whole window to become click-through, but only this part.
Thanks

The above code sets the window portion (painted by COLOR_KEY) transparent and click-through properly. Please check whether the actual color (used to paint the window) is plain (doesn't include any shade/shadow of COLOR_KEY) color.

Thanks Malli_S for your quick reply.
The actual color you mentioned is indeed the color key I set in SetLayeredWindowAttributes().
The evidence is that I don't see the colored parts (it is transparent, but unfortunately not click-through)
Thanks

Do a small test. Open the Notepad and put it behind your application's transparent area. And check whether the cursor changes to 'I'. This is because the specified color code does make window transparent but not the shade of color it has. If on any of the point, the cursor doesn't change, indicates the presence of the other color on that pixel. I just tested the same thing by changing the color into slight shady.
|

Actually shading doesn't work here at all. Because it's one color key (as opposed to alpha channel for instance), and a unique one, every pixel not in that color will be visible.
In my situation, I am using a window as a child control of IE. This makes click-through verification quite easy. The color-key colored parts are fully transparent and therefore I can see the IE page content behind it. However, clicking on hyperlinks for example is impossible.
Any ideas?
Thanks again
