How do I obtain the dialog box handle? Spy ++

Observe with SPY ++:
This is an MDI program. The window name of the outermost MDI main framework is known-"MDIMainFrame" ---
Then, there is a Class Name: MDIClient window ----------- B
Next, there is a window titled "hSDIClient" ------------ C
Then, there is a Class Name: AfxFrameOrView70 window ------- D
Then, there is a window under the Class Name: SysListView32 --------- E

HTemp = finddomainwex (getdomaintopwindow (), 0, "MDIMainFrame ","");
HTemp = find1_wex (hTemp, 0, "MDIClient ","");
HTemp = find1_wex (hTemp, 0, NULL, "hSDIClient ");
HTemp = find1_wex (hTemp, 0, "AfxFrameOrView70 ","");
HTemp = find1_wex (hTemp, 0, "SysListView32 ","");

In VB6, how does one automatically obtain the "Save as" dialog box handle?

Private Declare Function FindWindow Lib "user32" Alias "find0000wa" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
'Private Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long
Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, byVal wFlags As Long) As Long

Private Const HWND_BOTTOM = 1
Private Const SWP_SHOWWINDOW = & H40
Private Const SWP_HIDEWINDOW = & H80


Private Sub commandementclick ()
Dim h1, h2, Point As Long

Shell "NotePad", vbNormalFocus 'open NotePad
H1 = FindWindow ("Notepad", "untitled-Notepad ")
'Showwindow h1, 0' hide notepad window
SetWindowPos h1, HWND_BOTTOM,-100,-100, 0, 0, SWP_HIDEWINDOW

SendKeys "PowerBASIC China", true' type some characters
SendKeys "% FA", True 'Open the Save As dialog box

H2 = FindWindow ("#32770", "Save as") 'to get the handle of the Save As dialog box
'Showwindow h2, 0' hide and save as dialog box
SetWindowPos h2, HWND_BOTTOM,-100,-100, 0, 0, SWP_HIDEWINDOW

SendKeys "C: \ PowerBASIC.txt", true' input file name
SendKeys "{TAB}", true': Focus on the Save button
SendKeys "{ENTER}", true' press ENTER
SendKeys "% (FX)", true' exit notepad
MsgBox "your file has been saved to C: \ PowerBASIC.txt! "

End Sub

 

Q: sendmessage requires a dialog box handle, but the dialog box does not have a title and is hidden. The handle cannot be obtained using Findwindow. How can I obtain the handle of this dialog box?

You can use the GetDlgltem function by using any parent-child window pair, not just a dialog box. As long as the hDlg parameter specifies a parent window and the Child Window has an independent identifier (as specified by the hMenu parameter in CreateWindow or createmediawex of the Child Window ), getDlgltem returns a valid handle to the subwindow.
