win.SendMessage

[cpdlink]

hello everybody,

i am trying to write a few characters into a vb texbox using the code below:


local h_parent = win.FindWindow("ThunderFormDC", "MessageReceiver");
local h_child = win.FindWindowEx(h_parent, nil,"ThunderTextBox", nil);
local msg = 'abc123'
print(h_parent .. ' - ' .. h_child);

win.SendMessage(h_child, win.WM_SETTEXT, 0, msg);
and it doesn't work - the error is:

"parameter 4 must be a number or nil, not a string"

same thing works from an other vb application:


parent = FindWindow("ThunderFormDC", "MessageReceiver")
child = FindWindowEx(h_parent, ByVal 0&, "ThunderTextBox", vbNullString)
sMsg = "abc123"
Debug.Print h_parent & " - " & h_child

SendMessage h_child, WM_SETTEXT, 0&, ByVal sMsg
can anybody tell me how to do this using sendmessage (sendkeys is not a reliable solution - sometimes it works, sometimes it doesn't)

any help would be greatly appreciated
thanks,
chris

That will not work from Lua. Try using the keyboard actions to do this.

sorry to hear that,

is this wrapper going to be developped further more, because in my opinion we are missing a big deal of the functionality of this powerful function (probably the most powerful function in windows)

are there any other ways to send a text message from girder to an application?

i am basically looking at sending the channel number from a girder variable to an epg program

for sure i can create a file in a certain folder having the channel number as name, but i thought there is something more "elegant" than that

thank you for for the answer ron,
chris.

Try using the keyboard actions, that is what everyone uses to do those tasks.
