Hello,
I have an application that is not mine, that has 6 textboxes with values on it.
I am trying to use the windows API to retreive the values from those textBoxes. I know that they exists in a control named "Panel1".
So I have come so far in the code like below to find the "Panel1". But from here, I can't manage to find the textboxes and get their values?
I have used "SysExp" software which do find those values for those textboxes so it is possible in somehow.
Code attempt:
[DllImport("user32.dll")]
static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, int wParam, [MarshalAs(UnmanagedType.LPStr)] StringBuilder lParam);
private void button1_Click(object sender, EventArgs e)
{
foreach (Process p in Process.GetProcesses())
{
if (p.MainWindowTitle.ToString().ToLower().Contains("applicationname"))
{
IntPtr applicationnamewindow = p.MainWindowHandle;
List<IntPtr> GetAllChildrenHandles = GetAllChildrenWindowHandles(applicationnamewindow, 100);
for (int i = 0; i < GetAllChildrenHandles.Count; i++)
{
try
{
IntPtr childHandle = (IntPtr)GetAllChildrenHandles[i];
const int WM_GETTEXT = 0x0D;
StringBuilder sb = new StringBuilder();
IntPtr retVal = SendMessage(childHandle, WM_GETTEXT, 10, sb);
if (sb.ToString().ToLower() == "panel1")
{
//Inside this panel1 window. There exists 6 textBoxes. How to find them and get the value from them???
}
}
catch { }
}
}
}
}
