A sub menu problem

[rdcody]

Hey,

I posted a question in api yesterday, but the one person that responded
didn't have the time to help much. This is a more simple version of the
same question. If I'm not suppose to ask basically the same question in
another forum, then let me know and I will remove it. This is really bugging
me!

Here we go...


mnuMain
....mnuOpen

In the code below, I can get the height of the main menu, and the
.left position of the text. If you click on mnuMain, the first item is
mnuOpen. Here's the question...

How can I retrieve the same information for mnuOpen as I did
for mnuMain?

Private Type RECT
        Left As Long
        Top As Long
        Right As Long
        Bottom As Long
End Type
 
Private Type DRAWITEMSTRUCT
        CtlType As Long
        CtlID As Long
        itemID As Long
        itemAction As Long
        itemState As Long
        hwndItem As Long
        hdc As Long
        rcItem As RECT
        itemData As Long
End Type
 
Private Declare Function ModifyMenu Lib "user32" Alias "ModifyMenuA" _
(ByVal hMenu As Long, ByVal nPosition As Long, ByVal wFlags As Long, _
ByVal wIDNewItem As Long, ByVal lpString As Any) As Long
Private Declare Function GetMenu Lib "user32" (ByVal Hwnd As Long) As Long
Private Declare Function GetMenuItemID Lib "user32" (ByVal hMenu As Long, _
ByVal nPos As Long) As Long
Private Declare Function GetSubMenu Lib "user32" (ByVal hMenu As Long, _
ByVal nPos As Long) As Long
Private Declare Function GetMenuItemRect Lib "user32" (ByVal Hwnd As Long, _
ByVal hMenu As Long, ByVal uItem As Long, lprcItem As RECT) As Long
 
Private Sub Form_Load()
    Dim lngMenu As Long
    Dim lngSubMenu As Long
    Dim rcItem As RECT
    
    'get menu handle
    lngMenu = GetMenu(Me.Hwnd)
    
    'get rectangle for the first item of the menu
    Call GetMenuItemRect(Me.Hwnd, lngMenu, 0, rcItem)
 
    'height of first item in pixels
    Label1.Caption = rcItem.Bottom - rcItem.Top
    Label2.Caption = rcItem.Left
End Sub

Thanks in advance,
Ron

try this

Private Sub mnuMain_Click()
    Dim lngMenu As Long
    Dim lngSubMenu As Long
    Dim rcItem As RECT
    'get menu handle
    lngMenu = GetMenu(Me.Hwnd)
    lngSubMenu = GetSubMenu(lngMenu, 0)
    'get rectangle for the first item of the menu
    Call GetMenuItemRect(Me.Hwnd, lngSubMenu, 0, rcItem)
    'height of first item in pixels
    Debug.Print rcItem.Bottom - rcItem.Top
    Debug.Print rcItem.Left
End Sub

Hey moeur,

I get 17 for the height, and 356 for the left. 356 is not right...it should
be 21 or 22.

I'm using Win98, VB5.

Thanks,
Ron

[rdcody]

I think the left should be maybe 16 in WinXP.

[moeur]

Are you looking for coordiantes relative to your form?
I think this gives coordiantes relative to the screen which means you'll have to subtract the left pixel location of your form.

[rdcody]

I need the measurement to the text of the sub menu. If you look at my
post yesterday, you'll see what I'm talking about...

this seems to work...

Private Sub mnuMain_Click()
    Dim lngMenu As Long
    Dim lngSubMenu As Long
    Dim rcItem As RECT
    'get menu handle
    lngMenu = GetMenu(Me.hwnd)
    lngSubMenu = GetSubMenu(lngMenu, 0)
    'get rectangle for the first item of the menu
    Call GetMenuItemRect(Me.hwnd, lngSubMenu, 0, rcItem)
    'height of first item in pixels
    'Debug.Print rcItem.Bottom - rcItem.Top
    'Debug.Print rcItem.Left
    Label1.Caption = rcItem.Bottom - rcItem.Top
 
    'the word "Open" in the submenu has 25 pixels
    Label2.Caption = ((rcItem.Right - rcItem.Left) - 25) \ 2
End Sub

What do you think? What operating system do you have?

[moeur]

try this

Label2.Caption = rcItem.Left - Me.ScaleX(Me.Left, vbTwips, vbPixels)

[rdcody]

I get 4

[moeur]

That is correct. the left position of the menu within the form is 4 pixels.

[moeur]

I'll dl your code from the other thread to see what you are trying to do.

[rdcody]

I'm trying to find the distance (pixels) from the left edge of the menu
to the left edge of the menu text.

thanks
