Newer reviews can be expected to be ongoing projects, with minor additions or corrections.

Note: When I rate stuff, a 10/10 does not indicate perfect in an absolute academic sense, but as in (at least) as good as could be expected at the time, minor flaws allowed. For portable devices typically limited by the size and weight. Value for money also counts. An electronic device that got a high score in 2005, most likely would seem like pure trash ten years later….


 

  • The EASY way to make a C# Windows.forms app really per monitor DPI aware

    As posted in another post, many apps have problems with windows scaling.

    See these screen-dumps from Windows lengthy guide that was found here

    UPDATE 2020. After Windows creators update, they made things slightly more complicated, sorry…

    Here is a reasonably minimalistic approach. You will often just need code like this:

        public partial class Form1 : Form {
             public Form1() {
                 InitializeComponent();
                 DPI_Per_Monitor.TryEnableDPIAware(this, SetUserFonts);
             }
             void SetUserFonts(float scaleFactorX, float scaleFactorY) {
                var OldFont = Font;
                Font = new Font(OldFont.FontFamily, 11f * scaleFactorX, OldFont.Style, GraphicsUnit.Pixel); 
                OldFont.Dispose();
             }
             protected override void DefWndProc(ref Message m) {
                 DPI_Per_Monitor.Check_WM_DPICHANGED(SetUserFonts,m, this.Handle);
                 base.DefWndProc(ref m);
             }
         }
    

    You will need to obey a few rules, but often it can be implemented in existing code in minutes!

  • Cases/shells for the Pro1, DIY experiments

    There are no official case(s) for the FxTec Pro1, so I have ordered over a score of cases/shells for various phones of dimensions close the keyboard part…

    Ten have arrived, nine Nov 13., and here are the preliminary results, and a flip case fitted

    Add Nov 21, two more have arrived, for Huawei P20  Pro and Note 7

    Add Dec 28, two more have arrived a week ago, Flip cases for Huawei P20  Pro and they are better (the above image)

    Add Jan 23, a little more on a P20 Pro flip, reverting the inner part

    Add Apr 1, a better shell case with strengthened corners.

    Add Aug 6, a protector for the top half – disabling edge interaction

    (Will update if any of the remaining ones proves a better fit)

  • Save and restore positions of windows, WindowsPosSaveNRestore

    WindowsPosSaveNRestore is a tool to save the position of windows for later restore

    This is primarily useful if you frequently change display configuration, say add/remove external monitor(s) e.g. by docking, or turning a device with autorotate active.

    Windows also has the bug that it sometimes cram all open windows (and icons [+]) on the primary screen on sleep.

  • Windows TreeView with e.g. multi-line tree content

    Some claim that you need a third party tool to have a TreeView vith multi-line text (outside WPS).

    But it is actually rather easy to do with a few additional steps with the standard TreeView.

  • A little post on keyboard phones, and the few alternatives available

    Since BlackBerry-phones are now seeming to come to a complete end (not even licensed devices), the options for keyboard phones are even more sparse.

    I guess no one reading the blog is unaware that I go for the Pro1.

    But in all fairness there are alternatives.

    2020-04-12 Updated with the Astroslide announced for spring 2021.

Newer postings are in English (well sort of, bare with me, non-native…), some earlier than 2010 just blunt copies of the texts in Danish.

Collecting of old stuff started May 2015. Entries are generally attempted dated with original stamps, even if they are somewhat updated since, several reviews have been ongoing ‘projects’.
