console.log(‘\033[2J’); This works on linux. Not sure about windows. You can “trick” the user using something like this: var lines = process.stdout.getWindowSize()[1]; for(var i = 0; i < lines; i++) { console.log(‘\r\n’); }
The way to go is named pipes, you’ll probably have to take a look at the communication across different Integrity levels. This article explores how to do this in vista. Although it’s written in c++ it’s just basic Windows API calls, so it should translate fast enough to Delphi. If you want to search for … Read more
The problem is that your application does not contain an assembly manifest with a requestedExectutionLevel. Background All correctly written Windows applications are required to have an assembly manifest. And starting in 2006 one of the elements you’re required to have is a requestedExecutionLevel that specifies if your application can only function if the user is … Read more
The big thing that changed between Windows XP and Windows Vista/7 is the introduction of UAC which means that users, even if created as administrators, don’t routinely have read/write access to “important” locations such as the %programfiles% (Usually C:\Program Files or C:\Program Files (x86)) directory. This is why your application works on Windows XP and … Read more
If you want to register the association for every user, write your data to HKEY_LOCAL_MACHINE\Software\Classes If you want to register the association for the current user only, write your data to HKEY_CURRENT_USER\Software\Classes This is how to do the latter: with TRegistry.Create do try RootKey := HKEY_CURRENT_USER; if OpenKey(‘\Software\Classes\.myfile’, true) then WriteString(”, ‘MyAppDataFile’); if OpenKey(‘\Software\Classes\MyAppDataFile’, true) … Read more

What am I doing wrong or what should I be looking for? Is it reasonable to expect backspace, specifically, to work? No, IDLE does not support backspace, nor carriage-return, nor formfeed, nor ANSI escape sequences. You are expecting \b to move the cursor one cell to the left in IDLE’s interactive shell window. It doesn’t … Read more
The following will work in XP, I have no Vista machine handy to test it, but I think your issues are steming from an incorrect hWnd somehow. Anyway, on with the poorly commented code. // The state of our little button ButtonState _buttState = ButtonState.Normal; Rectangle _buttPosition = new Rectangle(); [DllImport(“user32.dll”)] private static extern IntPtr … Read more
Your problem is that the variable get replaced when the batch processor reads the for command, before it is executed. Try this: SET temp=Hello, world! CALL yourbatchfile.bat And you’ll see Hello printed 5 times. The solution is delayed expansion; you need to first enable it, and then use !temp! instead of %temp%: @echo off SETLOCAL … Read more
All you have to do is use the runas command to run your program as Administrator (with a caveat). runas /user:Administrator “cmdName parameters” In my case, this was runas /user:Administrator “cmd.exe /C %CD%\installer.cmd %CD%” Note that you must use Quotation marks, else the runas command will gobble up the switch option to cmd. Also note … Read more
