    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$.
    Always use [code][/code] tags when posting code.

    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
