Thanks Jim.  I'll try them out.

I've modified my version of Jim's test app as follows...

1)   Added AdjustWindowRect() functionality so that one can place controls right up against the bottom or right edge of their parent when designing the layout and not have them clipped when used on other operating systems other than the one on which form design took place;

2)   Added XP Theme functionality as in the original HelloDDT.bas sample app being emulated by SDK techniques;

3)   Added DPI Awareness by calling SetProcessDPIAware() or adding it to the manifest and performing the necessary modifications to window and control sizings. 

The smallest sizes I can get the app down to using VC15 and VC19 with various compilation/linkage setups are as follows...

Code Select Expand


//  9,216 UNICODE, x64, VC19, TCLib, DPI Awareness Set In Manifest (Adds 1024 Bytes!!!)
//  8,192 UNICODE, x64, VC19, TCLib, DPI Awareness Set SetProcessDPIAware() Api
//  7,680 UNICODE, x64, VC15, TCLib
//  8,192 ANSI,    x64, VC19, TCLib
//  7,680 ANSI,    x64, VC15, TCLib
//  6,144 UNICODE, x64, VC15, TCLib, DPI Aware, But No Dialog Fonts, AdjustWindowsRect(), Or XPThemes
// 90,112 UNICODE, x64, VC19, LIBCMT
// 42,496 UNICODE, x64, VC15, LIBCMT


Interestingly, setting DPI Awareness via a manifest as opposed to calling SetProcessDPIAware() adds 1 k or 1,024 bytes to the executable, i.e., 9,216 bytes verses 8,192 bytes in VC19 (Visual Studio 2015).  That kind of surprised me.  I was wondering if by setting both DPI Awareness and Themes in the manifest and removing the SetProcessDPIAware() and associated function calls in the Cpp file I could perhaps shave a half kilobyte or full kilobyte from the executable.  But it seems to work the other way around.  It costs more to do it via the manifest, seemingly.

Here are all my code files...

// XPtheme.xml

Note in the above that the processorArchitecture setting has to be changed to "amd64" from the original "x86" in the PowerBASIC version.  Also, if DPI Awareness is set in the manifest (which adds 1,024 bytes), this XPTheme.xml file must be used for it to work on Windows 10 (Win 8 too I guess)...

To build the version with DPI Awareness set in manifest, comment out the SetProcessDPIAware() in WinMain(), and remove function SetMyProcessDpiAware().

To compile the resource script into a resource file I do this...

Code Select Expand


rc.exe /v /foHelloRes.res Hello.rc


That creates a HelloRes.res file.  Then use cvtres.exe to create an obj file...

Code Select Expand


cvtres.exe /MACHINE:X64 /v HelloRes.res


That HelloRes.obj file then gets fed into the linker with the rest of the libs/object code as seen in my compilation strings at the top of HelloSdk.cpp.

I think that size is pretty terrible for such a simple app as this.  Its 7.5 k with VC15 and 8 k with VC19 – UNICODE or ANSI.  As I mentioned its 9 k if DPI Awareness is set in the manifest.  For something as trivial as this I'd expect about 5 k as being reasonable with TCLib.  Which got me to wondering why it is so big?  And I guess I have to accept Jim's statement that resource editor created apps beat SDK style apps size wise.  Or do I?

Well, in ruminating about it for awhile I decided there's a whole lot of stuff going on in that app that I would never do.  Its there because I simply copied code that Jim provided with his test app.  For example, all this stuff in my fnWndProc_OnCreate()...

Code Select Expand


hFont = (HFONT)GetStockObject(DEFAULT_GUI_FONT);
// hCtl = CreateWindowEx( for edit control )
SendMessage(hCtl, (UINT)WM_SETFONT, (WPARAM)hFont, (LPARAM)0);
// hCtl = CreateWindowEx( for OK Button )
SendMessage(hCtl, (UINT)WM_SETFONT, (WPARAM)hFont, (LPARAM)0);
// hCtl = CreateWindowEx( for Cancel Button )
SendMessage(hCtl, (UINT)WM_SETFONT, (WPARAM)hFont, (LPARAM)0);

   
...which changes the font of the three child window controls.  What purpose does that serve?  I can't see any whatsoever.  What I'm guessing is that Jim is attempting to exactly emulate the fonts used in resource created dialogs.  But why is that the standard to which SDK created windows must conform?  By dropping those four Api function calls my 7,680 byte VC15 created app loses 512 bytes and comes in 7,168 bytes.  And the resulting app looks better in my opinion than the one emulating resource dialog fonts.

Next in line for abscission would be all the AdjustWindowRect() stuff.  I have to admit I'm real glad I now know about that function (and AdjustWindowRectEx() too), but by simply refraining from placing controls right up against the bottom or right hand border of the window one can easily dispense with it to no ill effect.  With that gone and all its associated baggage and variables, our fnWndProc_OnCreate() reduces to simply this....

...which is 28 lines compared to the original of 39 lines.  Unfortunately, I'm still at 7,168 bytes. 

Next, for me at least, I'd be happy to settle for just buttons and edit controls without all the XP Theme stuff.  Horrified by that comment, and thinking I'm some kind of cave man or something?  Completely lacking all aesthetic sensibilities of what is right and beautiful?  Maybe So.

By removing the XPTheme manifest file and the calls to InitCommonControlsEx() and that associated baggage (no need for rc or cvtres) we're down to simply this as a fnWndProc_OnCreate()...

...which is only 24 lines of code, and our exe is now only 6,144 bytes, is still High DPI Aware, UNICODE, x64 architecture, and will look quite satisfactory on any Windows Operating System (I've tested it on everything from Win 2000 on up).

So adding themes, AdjustWindowsRect() and stuff like that only costs two or three kilobytes which is certainly nothing.  But after all, this is just an academic exercise to see where bloat comes from!

Jim,

On your Reply #22 where you posted a version using a resource dialog compiled with Tiny C, you got the smallest number by far, which I believe was 5,120 bytes.  I don't believe I ever tested TCLib with just a resource script created window, i.e., without RegisterClass(), CreateWindow() and so on.  Would you mind trying that or posting your rc file so I can try it?  Just curious!

Fred,
  I've done some serious hacking on your TCLib but I think this will compile with your version.
My batch file auto compiles a resource file with the same base name as the c++ file sent it.
This is not the file I used for comparisons as I was showcasing bc9Basic and TCLib so all the source in the tests are the same including  bc9Basic RTL code for string processing.
This one uses the "c" string copy and concat and it does reduce the size down to 5120.
Also note you do not need cvtres.exe. link is smart enough to link the *.res directly.
Check the first post for a link to a very good resource editor.

RC file
  My resource editor allows to save styles in hex so I don't have to include any windows *.h files in my rc scripts.

Fred,
  I changed the Tiny C version to use strcpy and strcat instead of the bc9Basic RTL string functions and it now comes in at 4608. But note this is 64 bit "c" ansi.
