When a memory device context is created, GDI automatically selects a 1-by-1 monochrome stock bitmap for it. GDI output functions can be used with a memory device context only if a bitmap has been created and selected into that context.
Here TempDC is not attached to any Bitmap, and therefore GDI function StretchBlt will not draw to TempDC.
You have to create a Bitmap compatible to your DC, and attach the same to temperory memory DC.

I'm freaking out guys I just don't see the leak ,Thanks in advance .
I'm trying to read the context of a PDF file(such as reading the word following the cursor) and
I used class wizard to add some header files (add class form Typelib ---> acrobat Access 3.0 Type Library<3.0>) to my project and include these header files in one .cpp file, but when compile, many compile error occurs.
what I know is as follow:
each header file imported include such line : "
#import "C:\\Program Files\\Adobe\\Acrobat 10.0\\Acrobat\\plug_ins\\Accessibility.api" no_namespace
when I comment out this line and then compile, everything is OK, but I'm not sure is it OK to do so, by the way I'm searching what the *.api file and its function on google and baidu(another search engine)
anyone who had read PDF file may help,
I really appreciate your help. thanks.
I have recently spent some time getting some of my apps looking right on XP styles, by adding a manifest resource, and also modifying some controls that are custom-drawn.
However, if I use my xp-style-enabled controls in apps which do not have a manifest, and therefore draw using the old style, I find that my controls still draw with the current XP style. I have used IsAppThemed() as a way of determining how to draw my controls, but I have found that this returns TRUE even though the app is not XP-style-enabled, making the control look odd! I have tried using IsThemeActive but this also always returns TRUE.
Does anyone know how I can find out if the app is XP-styled (ie the other controls are using the XP-styles)?

In case 1 you have declared the variable a but it has no value; in reality it will but its contents will be random. The second statement assigns the value 5 to variable a. These two statements do not need to be together, as a can have its value set or reset anywhere it is in scope.
Cases 2 and 3 are the same, the variable is declared and initialised at the same time.
One of these days I'm going to think of a really clever signature.
1. Declaration (after which the variable will be uninitialised, with an unknown value) followed by assignment.
2. Declaration with initialisation. For POD (Plain Old Data, built-in) types, this is effectively no different to 3. but with a class/struct type this would call a different constructor (taking an int parameter, rather than the default constructor).
3. Declaration followed by assignment. Again, for a POD type no different from 2. but with a class/struct type the value 5 could be implicitly converted to the class/struct type in a custom constructor before the assignment, or an assignment operator taking an int could be called.
In questions of declaration, initialisation, assignment and so on, what POD types do is well known and specified in the standard, but what class/struct types do depend on their implementation to a much larger extent.
