Hi all, thanks for al of your replies. I tried all of them with no success and then finally found the answer on the MS Support site http://support.microsoft.com/?id=328784[^] This has fixed my problem and I think the problem crept into my program when I integrated some code that someone I work with wrote in a text editor (he switches between Linux and Windows) so this seems the likely culprit. Thanks all again, Andy

Are you looking for MessageBeep()? Somethings seem HARD to do, until we know how to do them. ;-)_AnShUmAn_

cheers, I implemented it as I described but also used SetCapture and ReleaseCapture and it worked a treat :D

Well first off you are using dynamic memory just by using the ‘vector’ class, or any other STL collection, to store your records. Whether or not is frees the memory used by the first element is another story, it may just move the other elements down by one address, making the previous last element space empty (break out the pencil and paper). If the implementation of the ‘vector’ you are using does that, then you can simply remove the first element and add the new element to the end, and you have met the requirement (no special coding required); provided your class does not allocate memory in its copy constructor. If you were dealing with a situation where you are supposed to write your own ‘vector’ type class, then I would say that instructor wants you to learn about ‘in place’ construction (look it up) using ‘new”. Sorry if that did not help, but it is something you need to examine in detail to understand.

cheers Mark, worked a treat

:doh: thank you, should have thought of that myself rather than looking at more complicated ways of doing it. many thanks

ok, I think I may not have explained it clearly enough, what I need is for the day field of the control to be selected (i.e. if the user types then the day changes). I'm using a Date Time control which is liniked to a CDateTimeCtrl object. cheers,

You can also use the SS_NOPREFIX style on your static control. You may be right I may be crazy -- Billy Joel -- Within you lies the power for good - Use it!

As I understand, you will only need the DDK for the headers when you're compiliing the application, not for an end user to run it... Just make sure to test on a more normal envirnnment before distribution! Iain.

I'm going with the third one... :) Mark Salsbery Microsoft MVP - Visual C++ :java:

thanks for your reply, got it semi working using this just need to get my polygon region the right shape/size now! cheers,

You need to set the Notify property to True Why is common sense not common? Never argue with an idiot. They will drag you down to their level where they are an expert. Sometimes it takes a lot of work to be lazy

So does your (round) bitmap touch the four sides of the bounding rectangle? What if your bitmap was an oval instead? Would CreateEllipticRgn() still work?
