Hi Rajan,

there is an existing library for some of these functions. If you need more, you can use the "call library function node" to use the exported dll functions. Depends is a program with which you can read all exported function of a dll, but LabView do it as well.

Hi Mike

labview can read functions of a dll. But how can we get the parameters of a particular function & there valid values.

For example, let us take the case of mouse_event function in user32.dll

http://msdn.microsoft.com/en-us/library/aa932376.aspx  << see this link of the documentation of this function.

Now one parameter specified in this function is "dwFlags"  .. now how do we know that what value to input to this parameter for generating an event like >> leftup, leftdown or rightup, etc

Regards,

Dear rajan,

If you give 0 as input to dwFlags, it will select MOUSEEVENTF_ABSOLUTE  and

if you give 1 as input to dwFlags, it will select MOUSEEVENTF_MOVE

and so on.......

Hope it helps!

Hi Rajan,

you will find these information also in the internet. Here are the values for dwFlag for mouse event. It seems like they use one bit for every function.

Hope it helps
Mike
