But tried a whole day,none was work in maxscript,does any one has c# knowledge can help me to solve this problem?Below is one code I’ve tried,thanks:

I’d suggest you to use Spy++ and investigate what is happening when you click browser manually. Doing so will save you a lot of time.
ps. make sure to click after the page is loaded completely. And I suppose x and y should be relative to the browser window.
fn makeparam w l = ( bit.or (bit.and w 0xFFFF) (bit.shift l 16) )
mouseParam = makeparam mouse.pos.x mouse.pos.y
windows.postMessage hwnd 0x201 0x1 mouseParam
windows.postMessage hwnd 0x202 0 mouseParam
Hi Serejah,thanks for your good suggestion,I’ve never tried Spy++ before,I’ll try later,for your code,I just run and got error:
– Unable to convert: undefined to type: IntegerPtr
How to fix it?Thanks a lot!
Do you know what hwnd stands for? It is a window handle. You need to provide it in order to send your message to a particular window
rollout X "" (
button btn "press me" across:2
button send "send"
on btn pressed do messageBox "I'm mpressed!"
on send pressed do (
windows.postMessage btn.hwnd[1] 0x201 0 0
windows.postMessage btn.hwnd[1] 0x202 0 0
)
)
createDialog X
windows.postMessage X.btn.hwnd[1] 0x201 0 0
windows.postMessage X.btn.hwnd[1] 0x202 0 0
