Working with VGA screens

[yildi]

In the waiting, my problem comes from the fact that the Width property of a table gives the external width of the control but not the internal net width in which one can place the columns. This is perfectly normal of course. But I have a problem when I try to programmatically fix the the width of the columns of my table, like

colWidth = Round((Table1.Width)/Table1.ColCount)
For i = 0 To Table1.ColCount-1
	Table1.ColWidth (Table1.ColName(i)) = colWidth
Next

Indeed, when a vertical scroll bar appears, it eats the internal space of the Table and given that the columns' total width is equal to to table width, I also get a horizontal scroll bar. I ignore the exact thickness of these bars but I change the preceding code by

colWidth = Round((Table1.Width-rightMargin)/Table1.ColCount)

and adjust rightMargin by trial and error. But this is not a very elegant solution, since if I do not have a scroll bar, this leaves a small empty border on the left of the table, where the scroll bar is supposed to appear if necessary.

Am I stupid or is this a real aesthetic problem?

I hope that this is better understandable.

This is not a VGA problem. Same problem will appear on a regular screen.
I think that the best solution is to set the last column width a little wider than the rest of the columns.
When the scroll bar will appear it will truncate the last column.

Thank you Erel,
Yes, It is not a VGA problem but my efforts to make my program VGA compatible by adjusting different margins (in complement of the sizes of the controls) made this problem more bothering. Your tip is very simple and smart! I will definitely use it.

Best regards,

Instead of this code to double the size of everything. I'd like to know if it is possible to have two forms with duplicate control names with different resolutions?

[Erel]

It is not possible to have controls with duplicate names.

Hello Erel,
while I zaped through the Help-File of the CF 2.0 I found some AutoScale-Features in CF 2.0 like:
ContainerControl.AutoScaleDimensions-property
ContainerControl.AutoScaleFactor-property
ContainerControl.AutoScaleMode-property
Isn't it possible to solve the VGA-problem with the new CF 2.0 proprties ??

Best regards

There are some differences in the way Basic4ppc handles the forms, although these properties may help in a future version.

A bit late but I have only just arrived at this.
Would it be true to say that your snippet produces pixel doubling, and if not used, the VGA screen can have control sizes/positions set to my choice and the result will be true use of a VGA screen with optimized compiling? I get more on screen but would not be QVGA compatible.

This code snippet is not relevant since version 6.30.
You should use Forced QVGA if you want to use double pixel mode. Otherwise you will get true VGA screen on VGA devices.
