You don't really need to change the variable names in that code snippet. The intMin = the minimum number to pass to the random number function, and the intMax is the maximum number to pass. If you were to change the type of variable to pass/return you would just change the parts that say 'integer', and you should keep them the same type for this particular thing, since the X & Y coordinates use the same type of variable.

You could either add all the code in a separate module, or since you're just making a real small app, just add it all into the main form. Put the Dim r stuff at the top in the Declarations section, and then the rest of the original code I pasted anywhere else in the main form's code. It's just a function you're going to be calling to generate the random numbers for you.

Then in the mouse hover event, do someth9ing along the lines of:

' Play with the 0, 100 numbers here. This is where you'll probably want to take into account the locations of the container holding the chkbox
dim intX as integer = GenerateRandomNumber(0, 100)
dim intY as integer = GenerateRandomNumber(0, 100)
 
' Assuming the name of the checkbox is "chkSike" ...
chkSike.Location = New Point(intX, intY)
