How do I do to call a function of an injected dll (and give it's result)?
ah.. let me do another question:
I'm sending a window message from an application to another. The problem is.. the first one sends a value (on lparam or wparam).. and the 2° one receives a different value... why?
I Used this message type:
| Code: |
...
WM_READM = wm_user + 500;
...
procedure WMRead(var Msg: TMessage); message WM_READM;
...
procedure TForm1.WMRead(var Msg: TMessage);
begin
MessageBox(0,pchar(inttostr(Msg.LParam)),'Look',mb_ok);
MessageBox(0,pchar(inttostr(Msg.WParam)),'Look',mb_ok); {<-- I put a messagebox showing the lparam and wparam values to check if it's correct.. BUT R'NT }
end;
|
in the first application:
| Code: |
...
var x:dword;
begin
x:=dword(edit1.text);
MessageBox(0,pchar(inttostr(x)),'Look',mb_ok);
SendMessage(WINHAND,WM_READM,0,x);
end;
|
Why the values r coming different in the second app?

edit1.text is a pointer to the first character of the edit1 textfield
you give that pointer to x
and you give that address as lparam to the 2nd app.
Problem is that the 2nd app doesn't have a edit1 object, so it is pointing is a completly random location. (app2 doesn't have the memory of app1)
one way to solve this is using shared memory and give a offset into the object, using wm_copydata, or another method
