Changing screen displays under remote desktop application

[markftwain]

I post this to give other newbies like myself a head start. I hope it is usefull.

The general problem is correctly displaying a form across a remote desktop connection onto different size monitors.

My setup used a single vfp app with an initial form as the desktop. The displays went from small netbooks to larger 24" monitors. All forms had border style set to resize (default). I am using vfp9 and windows 7 as my terminal server.

In short, mwResize50 works well. But since I wanted the forms to use the entire screen real-estate, I made the following changes:

in the config file:
COMMAND=SYS(602,0) to turn off offscreen bitmaps.
SCREEN = OFF since I will be using a top-level form
RESOURCE = OFF since I do not need the resource file.

As directed,
in form.resize, put: m.This.mwResize1.Resize( m.This )
set form.mwresize1.lautsaveformsize = .t. (default)

And lastly, _screen.height and _screen.width never would give me the correct results in the remote desktop session, but the following seems to work correctly in the form show() method:

with this
local lnInitialWidth, lnInitialHeight
lnInitialWidth = .width
lnInitialHeight = .height
.width = sysmetric(1)
.height = sysmetric(22)+sysmetric(9)
.windowstate = 2
.resize()
.width = lnInitialWidth
.height = lnInitialHeight
endwith

Oh, setting the anchor property to 20 for pageframes and related controls yielded a very clean result in conjunction with mwResize.

Many thanks to Mike and Olaf for their suggestions.

Thanks for that nice summary.

I think the problem with remote clients is, that both the remote desktop and the local client can have a different screen resolution.

The original code is using:

    .Width = _Screen.Width  - SYSMETRIC(3)*2
    .Height = _Screen.Height - SYSMETRIC(4)*2 - SYSMETRIC(9)

This assume you use the screen and have that maximized. Sysmetric(1) is the Screen width, which means Desktop width, not _screen width, which is of course better than _screen.width. Actually, why not use Sysmetric(21) there? And I wonder if you actually need to subtract Sysmetric(9) from Sysmetric(22).

Anyway, that code for the Show() method actually computes the resize for the size the form will get, when Windowstate is set to 2.

Finally, I'll add two download locations:

Maybe you make a FAQ out of this. In fact I myself just did one FAQ about how to do single form applications, while I could have contributed more FAQs, I'm not good myself at adding to the knowledgebase.

Bye, Olaf.
