Re: strnage VS behavior
I don't see that this has anything to do with whether or not your OnKeyDown
tests for F12. Rather, the IDE uses F12 as a debug key and you just didn't
have a reason to press F12 until now.

Well.. after screwing around with this stupid thing for the better part of
the morning, I am stumped.
Here is the problem. I have a project that catches the OnKeyDown in the
CView. As I am adding functionality, more items will go in the switch
statement to respond to the keys, but I had 3 in there. I added VK_F12
and set it to open a modaless dialog box. I used Joe's modaless essay to
design the barebones functionality and get it working.
build and debug run.... push F12 and it a dialog comes up that says
"suchandsuch.exe has triggered a breakpoint"
I click ok.
then I get the dialog box about break or continue.
if I break... it dies there.
if I continue... the modaless dialog comes up.
So I thought... try to catch the exception. try, catch does not work.
GetLastError after every single call doesn't work.
then I placed breakpoints at every line inside the portion of the switch
statment that handles VK_F12. come to find out, the program is throwing
this error at random places in there. it behaves like the F12 key is
doing something outside of my program as well in the debugger that is
breaking the code flow or some such thing.
I think fine, I will pick a different key. I put VK_F10 in place of
VK_F12(meaning I REMOVED VK_F12 completely)
recompile. Run in debug. F10 does nothing. hmmm..... Press F12. BAM.
the code acts like I naever changed it. I look at the code... there is NO
F12 in it. yet it still catches F12 and goes into the error sequence I
I also thought I might have done the modaless dialog incorrectly, so I
switched it to modal. no dice... STILL same problem.
Yet I run the thing in release mode and it is all fine.
another thing I noticed... my VS2005 will in fact debug a release version.
I remember it used to throw some message about "You can't load debug
symbols" or something when you pressed F5 to run iin release... but now it
just acts like it is in debug mode and runs.
I tried to remove precompiled headers, but that was too much hassle so I
switched it to create precompiled headers instead of the use precompiled
when I press F12, it throws this "....breakpoint" message at different
places inside if the OnKeyDown handler(meaning the instruction pointer is
randomly placed in there)... yet all other keys I have set up work just
fine regardless. no problems
I cleaned the project. I tried to exorcise the project. nothing.
the application is an SDI application written in VS2005 on XP. I have a
single DLL linked in that I created which is a rendition of Joe's
multithreaded sockets code. this application creates 2 sockets connected
to two different servers and then passes info back and forth to both of
them. All of that has been working fine for much longer than today. I am
using the standard CView because the entore window area is custom drawn
and there are no windows controls on the client area.
Joe... if you read this, I can send you the entire project and you can rip
it to shreds if you wish.
so, I just need some help here. rather frustrated. thanks.
