SendMessage kk, WM_SETTEXT, 0, s
End Function

but look what appear in TextBox from exe2

what is wrong with my code
thanks in advance for any sugestion

for one thing you are not setting your string properly, unless of course gString is a string variable that holds your string data, in which case you would not need K$.

i declare gSTRING public, in main module.
but i try diferent syntax for SendMessage function, like:
SendMessage CLng(&HC0500), WM_SETTEXT, 0&, gSTRING
or like a simple test
SendMessage CLng(&HC0500),WM_SETEXT, 0 ,"Hello World"

in fact, no mather what is the gSTRING value, or lenght, i try to send numeric value trugh the another variable wich are declare integer, long, i try to send just strings with diferent lenght, bat all the time i receive the same result, like you see early.
how you see the results is all the time the same, strange and the lenght is the same.
i realy don't know what happend

for who want to know
solution is :

SendMessage CLng(&HC0500), WM_SETTEXT, 0&, ByVal gSTRING
