i have 2 applications.
my vb.net(**or c#**) project and external application

the external application is developed by delphi.
i want to extract information from this application (extract cells from the `TStringGrid` control).

extract the `1 2 str str` into my Vb.net project.

To make it more convenient to solve the question this is the download of the `external` application:
Download[^]

this is my code so far:

Declarations:

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Private Shared Function FindWindow( _
 ByVal lpClassName As String, _
 ByVal lpWindowName As String) As IntPtr
End Function
<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Private Shared Function FindWindowEx(ByVal parentHandle As IntPtr, _
                  ByVal childAfter As IntPtr, _
                  ByVal lclassName As String, _
                  ByVal windowTitle As String) As IntPtr
End Function

The Code:

Dim TheMainForm As Integer = FindWindow("TCells", "Cells")
Dim GV As Integer = FindWindowEx(TheMainForm, 0, "TStringGrid", "")

I'm sure that there is a answer to this question.
It is very important to resolve this question because without it my project will not move forward.
