How to capture the mouse

I just need to capture the mouse position, but with the event schema of windows, because i couldnt find a way to know when a column in mshflexgrid is resized, i could know when the user tries to resize it by getting the mouse event from windows, by using the message system, but it is still confusing how to get the info from windows.

if someone is really interesed about events and how to handle them with vb take a look at this place:

there is some source code, around 72 classes than handle around 1500 APIs, but i do not need all of them, and cannot understand fully how to use it.

Thanks for any info.
