Docker Desktop for Windows reports incompatible with Windows Server 2019 Essentials.

Logs indicates that hyper-v is required.

Here is a bat enabling all hyper-v related feature on Windows.

pushd "%~dp0"
dir /b %SystemRoot%\servicing\Packages\*Hyper-V*.mum >hyper-v.txt
for /f %%i in ('findstr /i . hyper-v.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"
del hyper-v.txt
Dism /online /enable-feature /featurename:Microsoft-Hyper-V -All /LimitAccess /ALL
pause

pushd "%~dp0"

dir /b %SystemRoot%\servicing\Packages\*Hyper-V*.mum >hyper-v.txt

for /f %%i in ('findstr /i . hyper-v.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"

del hyper-v.txt

Dism /online /enable-feature /featurename:Microsoft-Hyper-V -All /LimitAccess /ALL

pause

Also, Container

pushd "%~dp0"
dir /b %SystemRoot%\servicing\Packages\*containers*.mum >containers.txt
for /f %%i in ('findstr /i . containers.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"
del containers.txt
Dism /online /enable-feature /featurename:Containers -All /LimitAccess /ALL
pause

pushd "%~dp0"

dir /b %SystemRoot%\servicing\Packages\*containers*.mum >containers.txt

for /f %%i in ('findstr /i . containers.txt 2^>nul') do dism /online /norestart /add-package:"%SystemRoot%\servicing\Packages\%%i"

del containers.txt

Dism /online /enable-feature /featurename:Containers -All /LimitAccess /ALL

pause

But I tried Docker EE on Windows Server 2019 Essentials, still not working.

VMware Windows 10 Guest Shared Folder Fixer

Windows 10 Shared folder hang in VMware Fusion.
According to @steve goddard, this is caused by Microsoft upgrades destroying registry settings.

I wrote a VBScript check and fix the registry.

Click Button and Read Text from Other Program on Windows

By @sskaje
Link: https://sskaje.me/2016/05/click-button-read-text-program-windows/

I have a protected application on windows, normally my clients have to run that program, click a button, copy some text from another text control, upload to somewhere…

I need to find a solution simulate button click and read the text control.

There are two buttons, generate and exit, and a text control.

Here is what I did in C++, build under Windows XP + Visual C++ 6.0/7.0 in CLI.

1 Run the program.

	STARTUPINFO si;
	PROCESS_INFORMATION pi;
	ZeroMemory(&si, sizeof(si));
	ZeroMemory(&pi, sizeof(pi));
	
	if (!CreateProcess(
		NULL,
		(LPTSTR)  "GetResult.exe",
		NULL,
		NULL,
		false,
		CREATE_NO_WINDOW,
		NULL,
		NULL,
		&si,
		&pi
	)) {
		DWORD errval = GetLastError();
		cout << "CreateProcess Failed: " << errval << endl;
		return 2;
	}

	Sleep(500);

STARTUPINFO si;

PROCESS_INFORMATION pi;

ZeroMemory(&si, sizeof(si));

ZeroMemory(&pi, sizeof(pi));

if (!CreateProcess(

NULL,

(LPTSTR) "GetResult.exe",

NULL,

false,

CREATE_NO_WINDOW,

NULL,

&si,

&pi

)) {

DWORD errval = GetLastError();

cout << "CreateProcess Failed: " << errval << endl;

return 2;

}

Sleep(500);

Sleep is required here, to ensure that you can find correct control.

2 Find controls

	int ctrlBtnGet = 0x01;
	int ctrlTxtResult = 0x03e8;
	int ctrlBtnExit = 0x02;

	HWND wGetWindow = FindWindow(0, "Window Title");	
	HWND wBtnGet = GetDlgItem(wGetWindow, ctrlBtnGet);
	HWND wBtnExit = GetDlgItem(wGetWindow, ctrlBtnExit);	
	HWND wTxtResult = GetDlgItem(wGetWindow, ctrlTxtResult);

int ctrlBtnGet = 0x01;

int ctrlTxtResult = 0x03e8;

int ctrlBtnExit = 0x02;

HWND wGetWindow = FindWindow(0, "Window Title");

HWND wBtnGet = GetDlgItem(wGetWindow, ctrlBtnGet);

HWND wBtnExit = GetDlgItem(wGetWindow, ctrlBtnExit);

HWND wTxtResult = GetDlgItem(wGetWindow, ctrlTxtResult);

These CtrlID can be read by many *Spy app on windows.

3 Perform click and read from text control

In my case, Sleep is also required after BM_CLICK was sent to target program, otherwise I may have to click more than once.
So, I wrote a loop

	int max_retry = 5;
	
	int retry = 0;
	
	int length;
	char buf[2048] = {0};
	
	do {
		SendMessage(wBtnGet, BM_CLICK, 0, 0);
		Sleep(300);
	
		length = (int) SendMessage(wTxtResult, WM_GETTEXTLENGTH, 0, 0);
		
		if (length > 0) {
			SendMessage(wTxtResult, WM_GETTEXT, sizeof(buf) / sizeof(buf[0]), (LPARAM) buf);
			printf("%s\n", buf);
			break;
		}
		
	} while (++retry < max_retry);

int max_retry = 5;

int retry = 0;

int length;

char buf[2048] = {0};

do {

SendMessage(wBtnGet, BM_CLICK, 0, 0);

Sleep(300);

length = (int) SendMessage(wTxtResult, WM_GETTEXTLENGTH, 0, 0);

if (length > 0) {

SendMessage(wTxtResult, WM_GETTEXT, sizeof(buf) / sizeof(buf[0]), (LPARAM) buf);

printf("%s\n", buf);

break;

}

} while (++retry < max_retry);

I tried GetDlgItemText and GetWindowText, neither of these two works to get text from the control.
WM_GETTEXTLENGTH and then WM_GETTEXT is the best choice so far as I know.

4 Click Exit

	SendMessage(wBtnExit, BM_CLICK, 0, 0);

1	SendMessage(wBtnExit, BM_CLICK, 0, 0);

Create Windows 7/8 Bootable USB Drive on OS X

This note works for Windows (e.g. Windows 7, Windows 8, …), Linux … ISO image only, and all commands in Terminal.

If you’re interested in using Disk Utility, try this: Create OS X Mavericks Bootable USB Drive from AppStore Release, but DON’T forget to unmount partitions.

To launch a Terminal, simply open Spotlight and type Terminal, in most cases, you can see Terminal listed after ‘Ter‘.

For Windows 7/8 or later, Boot Camp Assistant is the BEST tool.
In ‘Select Tasks‘, CHECK ‘Create a Windows 7 or later version disk’ and UNCHECK all others.
In ‘Create Bootable USB Drive for Windows Installation‘, choose the right usb destination disk.
