How can we show MDiChild form as Modal?

Dear All,

I have an MDI form and another form named frmTest which is its child i.e MDIChild property of frmTest is True.

In applictaion, I come across a situation where I have to show the frmTest as modal form i.e I want to do this:

frmTest.Show 1

But as it is MdiChild so I get error. Is there any way that I can keep frmTest initially MDIChild but when I need to show it modally I may do That.

Please help and Guide.

Thanks

you cant show a MDI child as vbModal... you need to use API to keep the "screen on top"

try this:
MODULE (.bas)

VB Code:

Option Explicit
 
Private Const GWL_HWNDPARENT = (-8)
 
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, _
                                                                            ByVal nIndex As Long, _
                                                                            ByVal wNewLong As Long) As Long
 
Public Sub KeepScreenVisible(frm As Form)
    'if the form is to stay on top, frm.hwnd will get the name of the form
    Dim KeepScreenOnTop As Long
    KeepScreenOnTop = SetWindowLong(frm.hwnd, GWL_HWNDPARENT, [hl]frmMain[/hl].hwnd)
End Sub

FORM LOAD (.frm)

VB Code:

KeepScreenVisible Me

NOTE: change the highlighted part to the MDI Parents form name.

Thanks. It works.
But the forms title bar gets grayed and user may get the feeling that it is inactive.

the titlebars that are lighter are those who do not have the form focus.

Sir, the form that is at top, the titlebar of that's form is inactive. It is really on top and not letting me to go on other form but its titlebar is also grayed. :(

title bar for what? can you send a screen shot?

thanks buddy
im facing the same problem. suppose i have a text box on it, im unable to enter text in it.

ive used that code many times and never had a problem entering text into the form.

sir as engineer said its title bar colour is gray like the form is not active,
Command button and other controls are working but as i said i cant enter text in the text box

is your app an MDI? can you upload it so i can see whats going on?

Can you set the Focus to that form, or a control on that form?

sure you can

Sir Im uploading the test project. Im using text box and im unable to perform mouse activities in it. suppose, i can not focus it or move curser through mouse. Kindly help me in this regard

you forgot to attach a necessary module file along!!

Sorry boss, please check the attachement

You can simulate vbModal by setting the other form(s) to Enabled = False

but if i have more then 200 forms then???????????????

You have 200 forms Loaded??? Even so you can create a simple loop through the Forms collection and disable them all.

thanks everyone, but if i use richtext box instead of simple text box it works fine. i think this issue is resolved. again thanks everyone
