here u defined IDD and initialized to IDD_PROPPAGE_MyVariable01 which is undeclared.
may be u changed the ID of the property page to some new value or the resource.h is not including in the compilation path of MyVariable01Dlg.cpp.

No, you've neither declared nor defined IDD_PROPPAGE_MyVariable01, only referenced it.

is it possible to have a standalone system tray icon without an exe ?
Typically an exe exposes a System tray icon .
However my requirement is such that I would want to launch an app after the user selects an element from the system tray. Is this feasible ?
For some of the icons (such as the LAN/Network status ) , I do not see a corresponding application in the taskbar. How are these implemented ?
Engineering is the effort !

No. If you wanted to do something like this you should make a small launcher application which manages the tray icon and launches the main application when needed.

There is quite a large amount of data that can be stored in an exe under the Version Info resource. Can I retrieve that data( if so how) at a later stage, even if the file is running.

See the GetFileVersionInfo[^] function and friends. You may also want to search this site for this function to find some examples.

Like this?

This , I thought would be simple. I have spent close to half a day figuring this out .
So I am working on a MFC dialog app that has a CPropertySheet object. I am using the property sheet in Non Wizard mode.
MyDlg::OnInitDialog(.)<br />
{<br />
<br />
..<br />
CPropPage1 *pPage = new CPropPage1() ; <br />
m_sheet.AddPage(pPage);<br />
if(!m_sheet.Create(this,WS_CHILD | WS_VISIBLE |WS_BORDER)) <br />
return FALSE ; <br />
<br />
m_bInitialized = true ; <br />
}
I am unable to size the propertyPage to fit the dimensions of the main dialog window.
What should I be doing to ensure that the current active page in the PropertySheet is contained within the bounds of the Main dialog .
This is how my dialog looks at this point ( awful !

Help is appreciated

Your example is a CPropertyView on a CFrameDialog?
So, your CPropertyView has to handle WM_SIZE and resize itself appropriatly.
Also, the View has to relay the message to the active page.
In addition to look at a few of the solution here on CodeProject, there is an article form a very interesting series):
Control Resizing[^]
Also, MS has a step-by-step walktrough[^].
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

So the main dialog window is not the property sheet itself?

dear all
i am really very sorry to ask such question, but no any friend around me,
how to generate the a mask by Gaussion function(2D) when sigma is changed? why its sum of all value in mask is fixed when sigma is changed? and how to produce a mask by c++? thanks a lot.

Hi, hope somebody can help me or at least give a comment.
I'm working on a viewer for large image but the memory become the limit to view the whole image.
An idea from other gigapixel viewer is to seperate the whole image into small tiles(256x256) for a number of zoom level, create DC in memory and dynamically display(OnPaint) only viewable part.
But I'm having difficulty implementing this algorithm like how will i change DC in memory while scrolling and I can't find an open source showing such.
Does anybody have an idea how to implement this?
Please explain logic in more details like when scrollbar moved, mouse scroll or OnPaint().
Or if you knew of a thread or open source implementing like this please let me know.
That's all thank you.

First, thank you for your time Rajkumar.
I have already seen that code and that is not the solution to my problem.
The bitmap the programmer referred as large was actually large enough for the display area or client rectangle but still can be loaded.
I actually mean "large image" that can't be loaded and will cause a memory error like a gigabyte size *.jpg image. The only way to load it is to tiled it into smaller size and manipulate like what HDView from microsoft or google map doing.
I just don't know how to implement it. I can't find detailed explaination regarding this matter.

Maybe CXImage article is helpful for you I guess you need to read image files your self instead use of functions like LoadImgae,CImage ,....(you can find this article on the codeproject).
