The PostMessage function... Sending Text to a Box

Hello,

This is probably a very simple solution... but of course it isn't simple if you don't know it. :)

I'm currently using the API Declare function PostMessage() to click existing Buttons on another application. I'm doing this by getting their Parent Window Handle and then the Button Handle with that by using FindWindowEx()

Here's a sample of how I'm doing this... maybe it will help someone out.


' Excerpt from function
MyWind3 = FindWindowEx(MyWind2, 0, vbNullString, "MyWindow") '
If MyWind3 <> 0 then 'Could be...
'looking for the Ok button

MYWind4 = FindWindowEx(MyWind3, 0, vbNullString, "OK")

If MyWind4 <> 0 then 'Found it
ClickButtonWithHwnd (MyWind4)

End If
End If
' End Excerpt

public Sub ClickButtonWithHwnd(byval Hwnd as Long)
' Quite a few API declarations are here... sorry for not including them.
Dim Button as Long
Dim ParentHwnd as Long
Dim tmpHwnd as Long
Dim X as Integer
Button = GetDlgCtrlID(Hwnd)
ParentHwnd = GetParent(Hwnd)
tmpHwnd = GetActiveWindow
X = SetForegroundWindow(ParentHwnd)
'This Type of command I know works...
X = PostMessage(ParentHwnd, WM_COMMAND, Button, BN_CLICKED * &H10000 + Hwnd)
X = SetForegroundWindow(tmpHwnd)
End Sub




Anyways, I now want to put some text into a textbox on another application's window by using the same method and PostMessage. I don't know the Message type for Textboxes and MSDN seems to have a type for all controls except for that one.

Does anyone have a complete list of these Message Types and better yet can anyone provide me with an example of how to do a text writing using the PostMessage function?

Thanks everyone!

Try to use SendMessage API instead of PostMessage

Call SendMessage(HWnd, WM_SETTEXT, 0, ByVal "YourText")

where HWnd is a handle of the window(text box) where you send the message

Thank you.. thank you. This does work. However, I ran into a problem where it is impossible to do what I said I was going to do. It turns out the application's textbox I was going to send all this wonderful text to doesn't have a handle! :P What a bummer. Thanks for the help though.

Not sure of your entire situation, but if you're also doing the coding on the "reciever" application you could put a hidden textbox that does have a hWnd on the form and send it the text. Then add the appropriate code to send it to the real textbox... Just a though....

Don't I wish I had control of the code for the other app... this would put to rest a mile long list of control issues I have with it. Unfortunately, I do not. Thanks for the tip though.
