Graphic Objects

[snorky]

I need some info on how to make a graphic object selectable after I've drawn it ( like in a DTP program ) So I can draw a rectangle and then go back to it later and select it and manipulate it etc. Anyone with any info or good links on how to do this kind of stuff ????

Regards,
Snorky

Bad news: In VB you can not select a graphic object. There is no event for mouse down, mouse up, etc.
But you can use a workarround: you can place a picture box on your form and inside the picturebox you place a graphic object. You can then select at runtime the picture box and move it arround (using moude down/move/up events of the picturebox control). This is the first idea that croses my mind...

Hope I've been helpful,

Thanks for the reply - is this true of all the .net stuff too ( C# ?) or is it a case of having to learn C++ to do this?

You could create a struct or class which defines the coordinates of your graphic object then in the mousemove event check the x and Y coordinates of the mouse and if it falls within your object's coordinates redraw accordingly.

how can I create a structore for a polygon?

 

[DrJavaJoe]

Do you mean the structure that is passed to the polygon api?

Private Type POINTAPI
X As Long
Y As Long
End Type
