MsgBoxEx - Extended Message Box

Based on the code from Aaron Young I found here : http://www.vbforums.com/showthread.php?t=17725,
I added some extra features :)

1) Now you can move and resize the msgbox easily.
2) Change Forecolor and Backcolor for the MsgBox.

Module Code (Post #6) : http://www.vbforums.com/showpost.php...46&postcount=6

Example (Post #7) : http://www.vbforums.com/showpost.php...51&postcount=7

Very nice additional features! Will you be fixing the button and text positioning when the msgbox is sized? ;)

Thanks :) I'll be adding it shortly :)

I concur with RobDog. Very nice! In fact, when you finish I think I'll pop this into a modMsgBox.bas file and make it standard module for all new projects. :thumb:

Thanks Hack :)

I updated the code. It resizes and moves the buttons now. I'm sure it's not perfect so I'm open to suggestions :)

In a standard module :

Example :

    Dim aButtons(2) As String
    aButtons(0) = "Go"
    aButtons(1) = "Come"
    aButtons(2) = "???"
 
    Caption = aButtons(MsgBoxEx("Text" & vbCrLf & "More Text" & vbCrLf & "Even More Text", vbCustom, "Title", , , aButtons, aButtons(1), 0, 0, 200, 300, vbWhite, vbBlue))
End Sub

Can we have a background picture on it ?

Well, in theory you should be able to, although I haven't tried it... Probably when the same message is called when you set the background color, instead of calling the SetBkColor API, you could call the BitBlt, right? Both take the hdc as a parameter to draw on. So I'm guessing it's possible, but not implemented in the above code :)

manavo11, if you get a chance, can you post your code in VB tags? When I copy your code and past it to a module, it is all bunch up on couple lines.

Thank You

Liquid Metal, I read a post that said to copy code (within VB tags) click the 'Quote' button which removes all the line numbers allowing you to copy and paste the code into your project :thumb:

Or check out MartinLiss' signature for his VB Code Copier fix.

How close does it get us to TaskDialog()'s functionality?

So long MessageBox and thanks for all the memories

I just clicked the Quote button on you and it worked!:D:p Thanks for the tip Lintz, it was good.:thumb: :cool: :afrog:

Glad to help :wave: :D

I got a question:

Code:

---

Public Function MsgBoxEx(ByVal Prompt As String, Optional ByVal Buttons As Long = vbOKOnly, Optional ByVal Title As String, Optional ByVal HelpFile As String, Optional ByVal Context As Long, Optional ByRef CustomButtons As Variant, Optional DefaultButton As String, Optional X As String, Optional Y As String, Optional Width As String, Optional Height As String, Optional ByVal ForeColor As ColorConstants = -1, Optional ByVal BackColor As ColorConstants = -1) As Long

---

Can't the bolded strings be integers?

Where is the bolded parts? It doesnt show.

I think it was in ref to this part ( the bold is hard to see, so I also changed the color)

Code:

---

Optional X As String, Optional Y As String, Optional Width As String, Optional Height As String

---

Doesn't it make sense to make those Longs instead?

-tg

Yes, if your passing numerical data all the time, as in coordinates, then it does make logical sense to change the signature to Integer or Long instead.

:) Well, I'm think that until VB recognizes "four hundred fifty-eight" as a number.... it's pretty safe (possibly safer) to change it to longs to allow 458...

:)

-tg

nice coding but cant we increase the font size......please

Dear All,

These code can not show the Unicode message.

LVD

vb6 & win 10
Tried code and have problems
1)The left lower corner of the msgbox is grey, and not color selected
2)Sub Script out of range error after pressing btn #1

Thanks for any HELP

NO HELP!!
So I took some ones advise and created my own.
Size, location, backcolor, forecolor, 1 to 3 buttons
button size, color & location
Message text size, color & location

:wave::wave:

Late to the party !
I need to change the Font for the Message Text and the BUTTONS.

How do i do that ?
Or is there a newer VB6 MsgBox code that has that feature?

there is an error in line 2 at character 21

This is a very old code, now it is no longer relevant. There are very good modern dialogues from Fafalone.
