I have code like this:
<br />
BOOL f() {<br />
...<br />
__try {<br />
...<br />
}__except(EXCEPTION_EXECUTE_HANDLER)<br />
{<br />
...<br />
}<br />
<br />
Object o;<br />
}<br />
The object declaration of variable 'o' is outside the __try/__except construct. I get the error:
warning C4509: nonstandard extension used: 'f' uses SEH and 'o' has destructor
Why is this so? I was thinking this should not be an issue as even if an exception is thrown, it will be handled by the __except block, and the exception stuff would end there. The object o is then created.
What can I do to fix this error?
thanks!

firstly, it is not an error, it is a warning. that means that the compiler saw that there is some coude that may cause some trouble, but non blocking for the execution of the program.
i have one question however. why are you using __try/__except instead of try/catch ?
refering to the MSDN[^], you have to declare o before the exception handling... (SEH means structured exception handling).

I have a question?
Are static members automatically removed from the HEAP or do we have to remove it manually.
Thanks.

I think your question is invalid.
Static members are never allocated on heap.

Thanks for that.
But now if it is allocated on the HEAP do we have to do the cleaning by ourselves.

No. It won't be allocated on the heap.

Static variables are in the read/write data segment when the loader loads the binary.
Info as to how much the size is, is embedded in the binary at link time.

static variables are not allocated on the heap, so u dont free them. simple rule is that, what u dont allocated u dont have to free it.
Typically a binary is divided into sections, also called as the segments.
data segment
code segment &
stack segment.
so your application may have additional data segment for static data also which are typicaly a read/write segment.
Constant data are stored in read only segment.
All these segments are calculated at link time. i.e. the memory is allocated statically and not dynamically so u dont have to clean up anything.

I have defined a hooker procedure which is named MyProc;when receriving messages this can be invoked,but i can't step into it for debugging,the breakpoints within it seemed invalid.
Why can't i step into the hooker?thank u

1. Set the DLL project as the active project
2. Insert some breakpoints
3. In the menu, Project / Settings / Debug, use an exe File as the debug session
4. Click OK
Now you can start debugging by pressing F5.
Note: you can only debug a process at a time.
you can also write your debug log to file.

what is the use of DrawDragRect function?
Hrishikesh
|
|
|
|
|
From MSDN...
Call it in a loop as you sample mouse position, in order to give visual feedback. When you call DrawDragRect, the previous rectangle is erased and a new one is drawn. For example, as the user drags a rectangle across the screen, DrawDragRect will erase the original rectangle and redraw a new one in its new position. By default, DrawDragRect draws the rectangle by using a halftone brush to eliminate flicker and to create the appearance of a smoothly moving rectangle.
The first time you call DrawDragRect, the lpRectLast parameter should be NULL.

Hello everyone! 
OK, I've seen how to do this on some website, but I'm creating my listbox with DDX_Control() instead of by creating a CListBox object... Anyone know how to do it with DDX_Control? Thanks!
