Below is a simple routine it am using reading the mouse coordinates. When I start the program and start reading mouse coordinates , I get an error message saying that the window or dialog is not open. I know the window is open . I am using multiple windows . I am reading coodinates off of one window and display those coodinates on the main window. Can anyone guess what I might be doing wrong??



SUB MOUSEMOVE
xx$=STR$(@mousex)
SETCONTROLTEXT wMain1,57,xx$
'--------------------------
yy$=STR$(@mousey)
SETCONTROLTEXT wMain1,58,yy$
return

Thanks Texas Pete

You're going to have to show more code than that.

TexasPete,
Without additional code to work with or knowing exactly what you are trying to accomplish...
...for testing purposes, try adding something like this to your main window handler:

Code Select
case @IDMOUSEMOVE

      setcontroltext wMain1,57, STR$(@mousex)
      setcontroltext wMain1,58, STR$(@mousey)


If needed, I'm guessing that you could call your existing sub routine directly from the @IDMOUSEMOVE routine just as easily.

HTH,

Everybody I figured it out. Sometimes I just need a little point in the right direction. Thanks for those that replied. My solutions was !!!

I had the @IDCLOSEWINDOW in the wrong place. However, I don't understand why the window was still open and visible on the screen while
the main window had been accidently closed.

you probably don't have the window declared properly.

But all of us can only guess when you don't provide the code to look at.

And it makes it even worse when you don't provide code and make absolute assertions ("I know the window is open") that we can't verify.

Eventually people will tire of having to "guess" in order to help you and I think you'll find that your help will drop off.

Thanks Everyone who tried to help.

Below is a simple example solution for reading mouse coordinates.
In Lb you did not have to do this. In CB doing  it this way does gives the
programmer more control over what is going on in the program.

Thanks to Doc , Aurel, and Larry who offers good advice.

P.S I finished  translating My first page from LB to CB. I have about 8 or nine more to go! I think it will start to move a little faster now.

aurelCB

Not bad but i think that would be better place edit controls in main window not in scrolling.
And one thing,please use button # code for code in post.

all best

  Pete, what aurelCB is suggesting is that you paste your code in brackets like this to make it easier for folks to read and/or to offer help. 

It really isn't a big deal for small snippets, but it's a good practice if you have quite a bit of code to share...
....and folks will appreciate it when you do.

Best regards,
-Doc-

TexasPete

Ok , Everybody I will use the brackets next time. I promise scouts honor!

Thanks
