I am coding a C++ project using MFC in Visual Studio (v16.5.4). The dialog editor seems badly broken on my HiDPI monitor (Lenovo ThinkVision 2880x1800 at 175%). It works fine on two other computers with standard monitors.
The dialogs get resized apparently randomly, and controls do not move correctly when I try to edit them. When I try to align controls the dotted selection rectangle may move, but the control often does not (in the editor). Sometimes, re-opening the editor shows that the control has in fact moved. When I build the project, the final display layout cannot be predicted from what appears in the resource editor.
I reported this to Microsoft using Visual Studio feedback, but they closed the report, saying it was "By design"!!!! They posted a link describing a feature which disables HiDPI awareness, but the link was for the Windows Forms Designer, not the MFC resource editor - there is no equivalent feature in the latter that I could find.
Does anyone else have this problem, or know of a decent work-around? At the moment I am transferring to my other computer with the standard display whenever I need to edit a dialog, which is monumentally inefficient for quite a large project.
I know this is an older post, but I thought what I found might help someone. I experienced the same issue today. It just happens that I have one monitor setup for 125% and one setup for 100%. The MFC dialog editor alignment operations do not work correctly on the 125% monitor but work fine on the 100% monitor. It would appear Microsoft isn't properly handling DPI in the dialog editor.

I'm using VS2017 CE along with Visual Micro Pro for Arduino programming, and consequently use VS2017's Serial Monitor window quite a bit. I recently moved to a higher resolution display, and now the serial monitor text is almost too small to read. I tried VS's Tools->Options->Environment->Fonts and Colors settings, but there's no 'Serial Monitor' window listed. I also tried '[All Text Windows]' but that didn't seem to have any effect either.
I also saw an old post on the Visual Micro forum that indicated that the serial monitor font size had been tied to the 'Text Editor' window settings, but changing that value didn't work either (although it did change the font size in the text editor window).
Any ideas how I might increase the font size in the Serial Monitor window on VS2017 CE, either through VS settings or VM settings?
TIA,
Frank
Never mind - I found the answer. If the Serial Monitor window is expanded far enough horizontally, a 'Terminal Font' option button appears - DOH!
Why do I always find the answer immediately after embarrassing myself by asking a stupid question on a public forum? ;-)

I have some legacy code made with Borland C++ Builder 6 that I have to port from Windows XP embedded to Windows 10 IoT.
It all seems to run properly, except dialog forms which aren't drawn properly. When I call ShowModal on the forms to show them, they flash quickly and then seems to disappear. However they are not gone, instead they are just not drawn and the form behind the dialog is seen. The dialog form buttons can still be pressed (if we know where they are).
I have tried all possible redrawing, refresh, repaint and update functions I could find, but nothing seems to work.
To make matters worse, dialogs containing actual control elements (like one containing a set of TSpeedButton elements) the controls are redrawn when moving the mouse over them, but anything else are not redrawn.
I have tried to search for similar issues but can't find anything for this.
Could this be solved? Or do we have to update to a newer Embarcadero version of the IDE to be able to solve it (which is a lot or work and not really something we can do at the moment)?
The problem was the use of a Billenium Software (now defunct) package for "fancy" transitions.
The transition in question "zooms" a dialog open, and it just doesn't seem to work. Disabling this transition will solve the problem of the disappearing dialogs.
I still don't know if it's a problem with the components Windows 10 compatibility, or with its 64-bit system compatibility.
How to create an application which stays in top of MacOS, something similar to below image. You can see the Evernote elephant icon.
I don't want to use xcode - because my application already built in QT, it has nice GUI, now I wanted to add extended feature something similar to Evernote. If I click on an elephant it will open a dialog box to write notes. In my case- it's a simple event like on/off buttons.
I have tried and created GUI widget apps but how to make one which resides like Evernote app ?
A custom pop up menu like the one pictured can be done several ways in Qt.
QML is the most modern way of making the menu with the customized styling you are looking for.
Apply the appropriate flags to the window/widget so it appears as a popup.
The same effects can also be done in QWidgets, but takes more code and probably will take longer to make. The flags you are looking for will be found under Qt Window Flags and/or under Qt Widget Attributes.
The stock stylings for Qt for different OS's deal mostly with title bars, status bars, buttons, drop downs, etc.
The base styles for Mac can be found here:
http://doc.qt.io/qt-5/gallery-macintosh.html
Once you go to a customized popup, you have to draw all of it yourself... but the native drawing elements in Qt are friendly enough and get you that look you are trying to do.
There are even some tools for exporting from Photoshop or Gimp directly to QML.

Hope that helps.
You are looking for a tray icon. Qt implements it in QSystemTrayIcon.
Further information
You may take a look at the System Tray Icon Example.
Many StackOverflow posts exist on this topic.
If you already have a program written for Qt, then you can compile and run it under MacOS/X much the same way you could compile it under (whatever OS you're using now). You'll need to install Xcode because Xcode includes the C++ compiler (clang) you'll need in order to compile your Qt program, but you don't have to use the Xcode IDE if you don't want to. Rather, you can either use the QtCreator IDE under MacOS/X, or you can simply open up a Terminal window and do a "qmake ; make" in the directory where your Qt-based program's .pro file is, and build it from the command line that way.
If, on the other hand, your question is actually about how to add an icon to the global menu of a MacOS/X desktop, then I don't think Qt has an API for that, so you'll need to drop down to using one of MacOS/X's native APIs. That will probably involve learning some Objective-C (or Objective-C++, if you prefer), but integrating a bit of Objective-C/C++ into your Qt app is doable with a bit of work.
I just wondering how Windows create this window?
I mean what styles applied to that window, I just want these styles on my project.
As info I use MS Visual C++ 2008.
Thanks
There's no easy way! There's no public API for using "the Windows 8 style", or the style of any other release. You'll just have to replicate it by hand, comparing it pixel-for-pixel against a screenshot. Then update your application with the next release of Windows!
Because they change the metrics of these sorts of dialogs with each release, they can't produce a public library for "system-themed dialogs", because Microsoft would then be unable to change the design for fear of breaking someone's application that maybe uses a bit too much text, for example.
I am writing a C++ application and I have a Login Box that's shown in a regular Dialog Box Frame. I see that some people can SKIN the entire dialog box and makes it look really nice. I was wondering if anyone can give me some pointers as to how to do that.
I'd need more details to give you a good answer.
The answer very much depends on which OS you're using and how you're programming your GUI (for example on Windows - plain Win32, MFC, ATL, Qt, Windows Forms, WPF etc etc).
If you're just using the Windows API here's a link to get you started.
http://www.codeproject.com/KB/dialog/skinstyle.aspx
Beware: custom skinning dialog boxes can be a very large task if you want to customise the look of every control as you end up writing very complicated custom controls.
Alternatively do you just want to make sure that your dialogs appear with Windows XP visual style rather than pre-XP style? This will require changes to your application to use the new common controls and visual style. Note that this changes the behaviour of some Windows APIs and can potentially have side effects (see ISOLATION_AWARE_ENABLED).
