Thanks for replying but
when i send character using PostMessage() from my application then it works.
See this,
<br />
PostMessage(g_hWndFocused, WM_CHAR, wp, lp);<br />
where :
g_hForeWnd : is handle to focused window of winword.
wp: is a character code.
lp: repeate code i.e. 1.
If we are saying that automation is required then above lines of code should not be work.
