usercontrol question (C++)

Just trying to learn how to create a usercontrol. I created a new Windows
Control Library (.NET) project and put in a status bar with a couple of
panels. Then display the time in one of the panels using a timer control to
trigger the update. I was trying to enter in some user defined properties
for the control and have some trouble understanding where to do it.

Where should I be declaring the private variables for properties? Declaring
tFormat, my variable used to determine how the time is presented in the
panel, where I have it doesn't seem right. I can only declare it there as
static.

Also I receive this error when building the control project? What is the
libc.pdb?

dlsTest warning LNK4099: PDB 'libc.pdb' was not found with 'C:\Program
Files\Microsoft Visual Studio .NET 2003\Vc7\lib\nochkclr.obj' or at
'C:\Documents and Settings\Sterling\My Documents\Programming Files\C++\User
Controls\dlsTest\Debug\libc.pdb'; linking object as if no debug info

I've included the code below. Thanks in advance for your help.
