If you only need a string message / bitmap then drawing manually is by
far the simplest solution.
If you want to use a real form and the progress manager does not suit
you, then you can display it from the resource yourself... call
FrmSaveActiveState, FrmInitForm, FrmSetActiveForm, FrmDrawForm to show,
then FrmEraseForm, FrmDeleteForm and FrmRestoreActiveState to hide.
To check for a "Cancel" button I periodically poll the queue with
EvtGetEvent, FrmHandleEvent (or better FrmDispatchEvent if you set the
event handler to your form). Then check for a ctlSelectEvent on your
button and get out of your processing loop.

Or the netsocket functions will timeout after 20 secs. I simply want
to put a please wait box over the current form. I dont need to
update this text in anyway, and I dont need user input (but adding a
cancel button there might be a good idea, but its not needed since
the network lib fucntions have a pretty low timeout value).
You can always just do it manually:
Before you start whatever it is, pick a rectangle on the screen that
you want to draw your Please Wait thingy into. Then, save its
contents with WinSaveBits(), draw a rectangle frame around it
with WinDrawRectangleFrame(), using a frame type of dialogFrame or
something along those lines (experiment), then draw the string
"Please Wait" centered in the middle of this rectangle with
WinDrawChars().
Then, do your processing, then finally do WinRestoreBits() to
put the screen back like it was before you messed with it.
That is the way that I have done it on many occasions. You'll have full
control over what get drawn when, and you don't have to worry about
which forms you are switching around. Remember that when you draw the
frame that it gets drawn to the outside of the rectangle, so it won't be
fixed after the simple WinRestoreBits() command using the same rect.
What I do is to define a rect, save bits, offset the rectangle to be a
little smaller, erase rect, draw the frame, do processing while drawing
whatever you want in the rect (could be a progress bar, count,...),
offset back to original size, WinRestore using restored rect coords.
This way I only define one rect, so it's fairly easy to keep things
straight. Bob
