Scrolling

A customer wants my app to fit in 640x480 and 600x800 screens. It won't! So - I figure to put the thing inside something with vertical and horizontal scroll bars. Ideally, the entire form should be scrollable. How can I do this?
Alternatively, what kind of container with scrolling can I put everything into? -- Norm

I guess you mean 800x600??

Yeah!

Hi,

Basically, you could use a picturebox to put all your controls on. Combined with some HScroll and VScroll control you could manage to scroll the picture box onto the form.
It will take some work to get to the results.
But, the following might save your day.
I once found a ScrollableBox UserControl on the web. I can't even remember where I found it, but its in source code, so you can have a peek at it or even use it in your project. All you need to do is copy and paste all the controls of your form to this container control... and voila, you got it scrolling, no matter which resolution you're running.
I copied a zipped version on one of my unused webspaces... just go get it !

The file will remain online until the end of the week...
Let me know if the link should not work correctly, and I'll send it by email.

Hope this helps,

Patrick.

Another thing you can do is make your main form an MDIChild form. Set its BorderStyle to 0 - None, and its caption to ""

When the form is shown inside the MDI form, scrollbars will automatically be functional.

e.g.

Private Sub MDIForm_Load()
'Form1 is borderless
Form1.Show
Form1.Move 0, 0
Me.BackColor = Form1.BackColor
End Sub

HI. Try this. Just copy this and paste in a module and then call it in each Form's Load event. In the form, set the tag as your current config. Size (Ex. 800x600 thenform1.tag=800)

Get back to me.

wsh2,
There are no pages to be found... it's a direct link to the file. It's works fine for me...
There is nothing else there except this file. I don't have any homepages, but I'm just using this space to share files with others...

Gracious! Wow!
Wish I could give points to all!
Thank you all very much.

AzraSound: Your code works fine. I made it work horizontally too. There is some control on my form for which "Top" cannot be determined at run time, says an error message. I'll track that down myself and see why not.

PatrickVD: The link you gave does not work. I'll e-mail you, if you don't mind.

Thanks to all again -- Norm

The Timer control's Top property can't be read at runtime.

Erick37

Actually it seems you can't read the Top property of any control that is invisible at runtime.

Hi all,

It seems I have some correction to make here... I made a small mistake in the URL of that downloadable file...
So if you're still interested in the ScrollBox Usercontrol, come and get it at :
http://club.euronet.be/patrick.vanden.driessche/ScrollBox.zip
This one should be working fine. It seems that the filename is case sensitive...
Sorry for this.

Patrick.

AshokKumar:
Your "resolutionmain" sub is fine. I can make it work by "hard-wiring" form.tag. How can I make it work automatically? That is, how can I get the current value to set form.tag to, from the current screen settings? I suppose there is an API function to get this number. I have Dan Appleman's book, but there are so many APIs I don't know where to look. -- Norm
