Displaying multiple VB forms at start-up

Ok for the first question:

Add a Module
In the module, add this code:

VB Code:

Public Sub Main()
 Load frm1
 Load frm2
 ' etc.
End Sub

Now rightclick the project name in the file list and select Properties, then change Startup Object to SubMain



For the screen size, you can use the SysInfo control (Project, Components...scroll thru list, find Microsoft System info, check the box by it, and hit OK)

Actually, you don't event need a module. You can just load the 2nd Form from the first Form's load event. Also, frm Load only calls the Form's load event. You need to use the Show method to display it on the screen (unless you already have the code to do this in your 2nd Form)

Code:

---

Form2.Show

---

For the screen size, and relative positioning, use the Screen object. It contains a Width, ScaleWidth, Height, and ScaleHeight property.

OK I'll concede the Show thing but loading from Sub Main is better, because if you reload the form later it will try to reload the other form, and if the other form is still open -- poof, you have a crash.

Also, loading from SubMain is better coding practice because its easier to follow.

To MLewis,
Thank you ! Thank you! Thank you! The Microsoft Sysinfo control did the trick. Here's the code that the I was able to put up in the Module's Sub Main():


Public lngHeight as Long ' variable to hold the screen's workarea height


Public Sub Main()
lngHeight = MDIForm1.SysInfo1.WorkAreaHeight
frmLibrary.Move 0, 0, Screen.Width / 5, lngHeight
MDIForm1.Move Screen.Width / 5, 0, (Screen.Width * 4) / 5, lngHeight
frmLibrary.Show
MDIForm1.Show
End Sub




Thank you again!!!!!

If you don't want to use a control for getting the workarea, you can use the SystemsParameterInfo API function.
The comments are in Dutch, sorry.

Put the following code in a standard module (.bas)

Code:

---

Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByRef lpvParam As Any, ByVal fuWinIni As Long) As Long

Public Type RECT
    Left As Long
    Top As Long
    Right As Long
    Bottom As Long
End Type

Private Const SPI_GETWORKAREA = 48

Public Sub GetWorkArea(ByRef udtRect As RECT)
' deze functie haalt de afmetingen van de workarea van de desktop op
' de taskbar, en application bars blijven hierdoor zichtbaar
Dim lngRet As Long
    ' haal de workarea op (functie retourneert afmetingen in pixels)
    lngRet = SystemParametersInfo(SPI_GETWORKAREA, 0, udtRect, 0)
    ' omrekenen naar twips
    With udtRect
        .Left = .Left * Screen.TwipsPerPixelX
        .Top = .Top * Screen.TwipsPerPixelY
        .Right = .Right * Screen.TwipsPerPixelX
        .Bottom = .Bottom * Screen.TwipsPerPixelY
    End With
End Sub

---

You can use the function like this:
In a form

Code:

---

Private Sub MDIForm_Load()
Dim udtRect As RECT
    ' haal de maximum afmetingen op van de desktop
    Call GetWorkArea(udtRect)
    ' resize naar de maximale afmetingen
    Me.Move udtRect.Left, udtRect.Top, udtRect.Right - udtRect.Left, udtRect.Bottom - udtRect.Top
