GetClientRect returns wrong values

The function GetClientRect returns wrong values for Right and Bottom if the windows text size (DPI) is set to 110%.
The text size 100%, 125% or 150% works fine.
With all other text size values the function GetClientRect returns wrong value.

I use this code at the resize event of the command bar:

cbrMenu.GetClientRect Left, Top, right, bottom
picMain.Move Left, Top, right - Left, bottom - Top

Example for windows text size (DPI) 100%:

You see the black border of the picture box at every side.

Example for windows text size (DPI) 110%:

The picture box is too large now. The black border of the
picture box at the right and bottom is missing.

Please can you fix this ugly bug?

I think it's best if you open a support ticket.

I have check your issue, and it reproduced with 110%, thought only with the bottom ('right' coordinate was ok)
Doubled checked the code and it really seems to be fine, it's using Microsoft function TransformCoords
http://msdn.microsoft.com/en-us/library/windows/desktop/ms692818(v=vs.85).aspx
Which gives some more ole points than needed in non-standard DPI configuration.
Looks like a bug of TransformCoords?
It was 7 points in my case, so i believe it excludes any floating point to integer conversion loss.
Did you tried a workaround: subtracting some space (1-2-3-4-5-6-... ?) from the right/bottom when using 110% DPI?

my answer at 03-Aug-2012:

Many customer use different DPI settings depending on the screen resoltuion and the real screen size.
110% is just one value i select for testing.
If you use a value different than 100,125 or150 creates this problem.
I tried to subtract some values but after that i found out that the difference changes after you resize the form.
If i make the form larger the difference get higher.
After the form gets smaller the difference gets smaller too.
No workout for that.
I have attached my vb6 test project for you. maybe you can reproduce the problem better.
Im testing with win7 64bit.

still waiting for any feedback now....
