I just resumed from hibernation, but the computer definetely wasn't out of system resources (physical memory 38%).

TC was freshly started, I started some programs from it and just before the error I pressed Ctrl+F. I chose to continue and everything seems fine.

Delphi creates this exception if it fails to allocate memory or window handles. I will check where exactly it failed, but I doubt that I can do much about it.

I guess there is some bug.

I have checked your stack trace now. The error occurs when TC tries to load the master password dialog. I have then put a breakpoint on all code lines where an "out of system resources" error could be created. The only code which could cause the error and which is called when opening the master password dialog is when loading the image of a (normally hidden) button in this dialog.

So my interpretation from the two linked bug reports is true here too: For some reason, Total Commander could not read from its EXE file totalcmd.exe. This usually occurs when TC is installed on a network drive which is currently unreachable. Windows may have disconnected the drive when you started hibernation.

Not in my case. It's on a local HDD.

I have it on local HDD too but encrypted and that might induce some "lag".

Well, here is the code from Delphi where the out of resources error is created:

Code: Select all

          DC := GetDC(Focus);
          if DC = 0 then OutOfResources;

...

              Bits := CreateDIBitmap(DC, BitmapInfo^.bmiHeader,  CBM_INIT, BitsMem,
                BitmapInfo^, DIB_RGB_COLORS);
              if Bits = 0 then OutOfResources;

The first one is when Delphi tries to get a so-called "device context", which is used to draw on the screen or to handle windows graphics objects. This should never fail, except when the system really is out of resources.

The second one creates a device independent bitmap. This can fail in two cases: Also when the system is out of resources, or when the bitmap data is invalid (e.g. wrong image dimensions or so).

In beta 5, I will catch this second exception and try create a 1x1 pixel bitmap. If this fails too, we are really out of system resources. If it doesn't fail, TC will show empty bitmaps in some places, but not show any error. I hope that this will fix the observed error...
