Thank you for your recommendation. I think it meets my requirements, but I cant implement it due to set-up problems. anyway, thank you very much!

Cheers,
John

You've taken up the red pill. Welcome to the dark world. I've spent enough time wrestling with plain C++. Some STL atleast? Nope. To be true our prototypes are almost built with plain C. They are kind enough to wrap them up in a class atleast. As you have mentioned in your thread, it's a s1,s2,s3,s4.. t1,t2,t3,var1*, var2**,var*** array1[], array2[]. all the way!.They look at "vectors" as a database! They feel it's complex operation to put something into a vector. Instead they simply use pointers. I felt dizzy at first but later managed to get along with them.

ATL, IMHO is much better for the above task. We can even write the ActiveX as you proposed: we've Jeff Glatt's wonderful article series on our side [^].

So, I'll take a single five, I think.

When you change the font of a combo box, how do you get the combo box to resize itself correctly, or what is the right way to do this manually? When I send a WM_SETFONT with a new font handle nothing happens.

You'll have to do the resizing yourself. The GetTextExtent family of APIs can help.

You may need to invalidate the control window so it redraws with the new font.
Also, make sure your font handle does not go out of scope or get destroyed for the
lifetime of the control.

Thanks. I found that the culprit was having the CBS_OWNERDRAWXXX bit set. That basically has the control do nothing when the control's font is changed. So I experimented a bit and found that if I call CB_SETITEMHEIGHT once for the selection field (wParam = -1) with my calculated height, and then again for all the items in the control, and THEN called SetWindowPos with the new height of the window (also taking into account the new height for the items) that everything worked out hunky dory. In hind sight I guess this was obvious, but it took me awhile to clue in to it.

Hi. Any body could please advise on how to implement a simple c++ instruction to prevent another instance of the same program that is already running from being executed.
Many thanks

You can use Mutex to do single instance check.

I tried but it doesn't work. For it to work you'll need to use the old syntax (/clr:oldSyntax), which is incompatible with my application which uses a static library rather than dlls.
Thanks anyway

rp_suman's link is good, but there's a better article here on CP http://www.codeproject.com/KB/cpp/avoidmultinstance.aspx[^]
This is particularly good to read if you have a GUI for your app.
