Cross platform? UINT & LPVOID? Surely you're Joking, Mr. Subramanian!

That may pull a tough one on the OP. He may post a query asking how to port LPVOID to Linux. Laugh | :laugh:

CWaitCursor not working fine in Threads.

Hi all,
In My application before starting Worker thread i m using CWaitCursor but its not displayed.

even i try it inside of Worker thread but its not working here also.

so please tell me how can i use CWaitCursor in Worker thread.

thanks in advance.

There's a flaw in your logic here. If you compute things in a worker thread, it means that your UI will still be responsive. So why do you want to display a wait cursor ?

Actually i done calculation in worker thread and display sum result on modelless dialog box that show on Main dialog box,so i want to display wait cursor here .

You can do a BeginWaitCursor / EndWaitCursor.

Let the worker thread work and the UI thread handle the UI: setting the cursor is part of the UI.

You can use WM_PASTE, if it's an edit control, directly and your intention is to paste some text from clipboard. Also you can try SendInput[^].

You should not be doing such a thing though, you've been asking it for something like a month here. So...

Send key-stroke messages in this order:

Control (Key down)
S (key down)
S (key up)
Control (Key up)

Use PostMessage[^] with WM_KEYDOWN[^], WM_KEYUP[^] to send normal key press event.

Similarly use WM_SYSKEYDOWN[^] and WM_SYSKEYUP[^] for sending a CTRL key press event.

Hi,
what would be the output of following code:

main()
{
int a=1;
printf ("%d", a+=(a+=3,5,a));
}

In VC++ it is showing output: 8
In AS/400’s C showing output: 5

If it is complier dependent, plz tell me the logic of both the answers.

It's a correct answer, but maybe not what was intended.

It seems to be evaluating it as ((a+=3), 5, a) and returning the new value of 'a' (the AS/400 compiler returns the old value of 'a' I think).

I'll have to find a precedence table, as I'd have expected it to be (a += (3, 5, a)), which would give a different result (4)...

edit : looks like the assignment has higher precedence, according to MSDN. You learn something new every day Smile | :)

int <font color=red>a</font> = 1;

a += ( <font color=red>a</font>+= 3, <font color=gray>5, a</font> );

a += ( <font color=red>a</font>+= 3 ); //(Anything after the first comma will be ignored by the compiler. See <a href="http://msdn.microsoft.com/en-us/library/t29e07xd(VS.80).aspx">Sequential evaluation operator</a>[<a href="http://msdn.microsoft.com/en-us/library/t29e07xd(VS.80).aspx" target="_blank" title="New Window">^</a>]

a += ( a = <font color=red>a</font>+3) //but a was delcared 1, so the expression <font color=red>a</font>=1+3 makes RHS value as 4.

a += a; //But <font color=red>a</font> is 4 now before executing this statement.
        //Therefore adding another 4, the resultant  a = 8. Makes perfect sense to me.

But according to sequential Evaluation:
say If,

a=(b+=2,5,2)

then it will evaluate b+=2 but a will get the value 2, as I m using the braces here.

So i think in my question it is evaluating the a+=3 but finally it is resulting the value of last argument.

a += ( a+= 3, 5, a ); //a=1
a += ( a );//a=4

kindly correct me know if I m wrong.
