"Need help creating a dummy WSResponse object (Scala + Play)",
"I have a code sample as below where I am using WSClient to make API calls. I am using 2.5.x and Scala 2.11.11 (using WSClient provided by Play not stand-alone).

"How do I get the active ChildWindow of an application?",
"I have this problem: I have an handler to the mainWindow of a certain application, and I want to simulate a keypress on that application...\n\nI'm using sendMessage/postMessage api calls to do this. The reason why I don't use the .Net SendKeys function or the keybd_event of the win32 api, is that they simulate the keypress at a global level. In my case, the target application is not the top-active one (other application may be running in a higher z-level, hence covering the target app).\n\nThe problem with sendMessage and postMessage is that you must pass the handler of the exact childwindow where you want the key to be pressed. For example, in notepad, if I send the key to the handler of the mainWindow, nothing happens, I have to send the key to the handler of the child window that basically consists of the white canvas where you can write.\n\nObtaining the handler to the active child window is the problem. In the beginning, I was using the GetTopWindow or GetWindow(GW_CHILD) api calls, as it returns the most active child window. What I was doing was to keep calling the GetWindow(GW_CHILD) until I got a childwindow that had no more childWindows. This works ok for some applications like notepad or paint. However, in some cases (like firefox for example), it doesn't work. The reason for that is that the parent window has the whole firefox area, and its childwindow has the opened WebPage (like google). So, when I ask for the most active child window of the mainWindow, it returns the only child window it has, which is the one corresponding to the Webpage area. It only works if the active window is that one (like if the user is writing something on a textbox of a certain page). But if what is active is, let's say, the address bar, it doesn't work because the active window is not the child window but actually the parent... and I can't get this information programatically.\n\nI actually found a way of doing this, using the GetGUIThreadInfo api call, using the following code:\n\n // get thread of the main window handle of the process\n var threadId = GetWindowThreadProcessId(firefox.MainWindowHandle, IntPtr.Zero);\n\n // get gui info\n var info = new GUITHREADINFO();\n info.cbSize = (uint)Marshal.SizeOf(info);\n if (!GetGUIThreadInfo(threadId, out info))\n throw new Win32Exception();\n\n // send the letter W to the active window\n PostMessage(info.hwndActive, WM_KEYDOWN, (IntPtr)Keys.W, IntPtr.Zero);\n\n\nAnd it works very well: If the address bar is active, it sends a \"W\" letter to the address bar. If the search textBox of google is active, it sends the \"W\" letter to it... Perfect! However, this method can't be used by me for a simple reason:\nIf the target application is not the active window of the operating system, the ThreadInfo structure comes empty. For example, if I'm targetting firefox, it works if firefox is active (the top-most application, the focused/active one), but if, let's say, notepad is on top of firefox, it doesn't work, it is unable to get the active window handler.\n\nI know I can solve this by using the setForegroundWindow api call to activate the target application and then capture the handler of the active child-window but I didn't want to have to bring the target app to the foreground.\n\nI've also tried other techniques like AttachThreadInput() and GetFocus() api calls, which also works, but has the same problem: If the target application is not the active windows application, it doesn't work.\n\nSo basically I need to find some way of getting the handler to the active childwindow of an application even if that application is not the top-active one.\n\nAny ideas?\nThanks"

Even tough it is not implemented in all FTP servers, it has to come from somewhere. What is its purpose?\n\nFrom RFC 959:\n\n ACCOUNT (ACCT)\n\n The argument field is a Telnet string identifying the user's\n account. The command is not necessarily related to the USER\n command, as some sites may require an account for login and\n others only for specific access, such as storing files. In\n the latter case the command may arrive at any time.\n\n There are reply codes to differentiate these cases for the\n automation: when account information is required for login,\n the response to a successful PASSword command is reply code\n 332. On the other hand, if account information is NOT\n required for login, the reply to a successful PASSword\n command is 230; and if the account information is needed for\n a command issued later in the dialogue, the server should\n return a 332 or 532 reply depending on whether it stores\n (pending receipt of the ACCounT command) or discards the\n command, respectively.\n\n\nThis does not help me much either. Anyone bother shedding some light into this? \n\nIs it just a possibility to pass a string to be matched on the server?\nI.e. to create groups which be be given different access rights or something?"

"Including hidden data in an HTML page for javascript to process",
"I produce a complex HTML summary report from data in a database which could be a summary of maybe 200,000 rows in the database. The user can click a link to request an Excel version.\n\nWhen they do a JS script extracts the key components of the report and stuffs them into a form in a hidden iframe. This form submits to a server-side script which generates the Excel version of the report (without the graphics etc).\n\nAs the calculations for the report are complex and \"costly\" it makes sense not to run them again to create the Excel version as all the data is on the page already. Also the user may have customised the report once it is loaded and I can use JS to pass those preferences to the form as well so the Excel doc reflects them too.\n\nThe way I am doing this is to include the following for each component of the report that transfers to a row in the Excel version. I've hijacked an HTML tag that isn't otherwise used. \n\n <code id=\"xl_row_211865_2_x\" class=\"rowlabel\">Musicals}{40%}{28.6%}{6</code>\n\n\nThe code element above is a summary of the row below in the HTML report which becomes one row in the Excel doc and includes the label and various data elements. There may be a thousand or more such elements in one report. \n\n\n\nAs the data contains text I've had to use something like }{ as a field separator as this is unlikely to occur in any real text in the report. I have code set to display:none in the CSS.\n\nWhen the user wants an Excel version of their report the JS code searches the HTML for any <code> elements and puts their className and innerHTML in the form. The className indicates how to format the row in Excel and the data is then put into adjacent cells on the Excel row.\n\n\n\nThe HTML report shows one percentage base (they can toggle between them) but the user preference when requesting an Excel version was to include both.\n\nIs there a better way of doing this?\n\n(As this is a part of a complex web app no user is going to turn CSS off or lack javascript or they wouldn't get this far)\nADDED: I can't use HTML5 as the users are corporates often on older browsers like IE6"

I still get the previews.\nOn my note default messaging app it works, but it shows the dots. Any other good ideas to stop the preview.\n\nWe also shorten the link and track when someone clicks on it, so if it loads the preview it shows up as a click and the preview image sometimes we can't control, so we don't want to show it."

So one way or the other, I can't get it to work, these two DLLs are fighting. This code is referenced my multiple articles so I'm not sure what I'm doing wrong.

"Need Java Annotation to enforce javac -source option at compile time",
"We have some general utility classes in our large Java codebase that have to be deployed as a library in an environment where Java 1.6 is the only option. When this library is built, on infrequent occasions, we compile them with a Java 8 compiler with the -source option set to 1.6. The problem is, we've had to deal with compile errors that occur because someone has added code to the classes that use 1.7 or later Java language features. This happens because during the course of normal development, this code is developed and deployed in a Java 8 environment.\nWhat I'm wishing for is a built-in annotation that will cause compilation to fail if it contains any code that is not 1.6-compatible, regardless of the compiler version in use or the runtime version it's targeting. Unfortunately, that doesn't seem to exist. Would it be possible to create a custom annotation for this? None of the literature I've found on custom annotations talks about creating custom annotations that do their thing at compile time."

"How can a .NET code know whether it is running within a web server application?",
"I have a library code, which should be aware whether it is executed in the context of a web server or standalone application server.\n\nThe obvious that comes to mind is to check the name of the application configuration file and if it is web.config - then this is a web server, otherwise - standalone application server.\n\nAnother way is to look for something like \"Temporary ASP.NET files\" in the path of the shadow folder.\n\nBut I dislike both of these, since they seem too hacky and fragile. Is there a robust way to do what I want?\n\nThanks. \n\nP.S.\n\nOne may define a dedicated app config setting - IsWebServer, but I dislike it even more.\n\nEDIT:\n\nWhile looking for a solution to another problem, I think I solved this one - the details are here"

"Visual Studio metadata filenames are inconsistent",
"The following seems to be a Visual Studio 2017 bug. I will post it here to see if there are alternative explanations.\n\nSometimes Visual Studio will create a file with a file name ending in .cache and sometimes it will end with .Cache. The difference is only in the aspect of capitalization.\n\nAn example is this file, starting at a Visual Studio project directory.\n\n../ListEditor/obj/Debug/ListEditor.csproj.GenerateResource.cache\n\nIf there is something in the operation of Visual Studio that can avoid this bug I would like to know.\n\nThe following is \"background\" information about why this matters to me and is not essential to my inquiry.\n\nThis inconsistency in the file name is has no effect on the operation of Visual Studio and Windows because the operating system is case-insensitive. However, it does have a subtle effect in the intersection of robocopy and cygwin and diff --recursive. \n\nSuppose a backup is made and verified as follows.\n\nrobocopy c:\\users\\joe\\documents d:\\windowsbackup\\documents /XJ /MIR\n\ndiff --recursive --brief /cygdrive/c/Users/joe/Documents /cygdrive/d/windowsbackup/Documents\n\nrobocopy's economizing heuristic is that a copy is needed if there is a change to the size or timestamp of a file. In other words, robocopy is not perfect, but the verification is intended to catch robocopy's mistakes. These mistakes are admittedly unlikely when nobody is messing with the system clock and programs are not back-dating. However, when a large quantity of data is copied performing a verification might be considered prudent in order to detect corruption. Visual Studio needlessly alternating between .cache and .Cache creates a problem for the verification. Since the diff verification happens in cygwin, which is case-sensitive, the following will be output.\n\nOnly in /cygdrive/c/users/joe/Documents/source/repos/Auna4/ListEditor/obj/Debug: ListEditor.csproj.GenerateResource.cache\n\nOnly in /cygdrive/d/windowsbackup/Documents/source/repos/Auna4/ListEditor/obj/Debug: ListEditor.csproj.GenerateResource.Cache\n\nSo diff found a difference but it is not the kind of difference we care about and furthermore it declines to verify the file contents to detect corruption. One solution involves writing a script to collect the diff output and pass it to cygwin cmp to do the content verification that cygwin diff declined to do. (Diff is used because it supports recursion but cmp does not.)\n\ncmp /cygdrive/c/users/joe/Documents/source/repos/Auna4/ListEditor/obj/Debug/ListEditor.csproj.GenerateResource.cache /cygdrive/d/windowsbackup/Documents/source/repos/Auna4/ListEditor/obj/Debug/ListEditor.csproj.GenerateResource.Cache\n\nThe bottom line: robocopy is probably okay when there is no human nor programmatic altering of the system clock but for large amounts of data detecting corruption is nice to have but not readily attainable with the \"default\" tools given the Visual Studio file name bug. cygwin already stretches the definition of \"default\" tool. For my purposes, the most popular system is often the default choice if I am concerned about bugs and support. I think cygwin was very popular before Microsoft added the Linux subsystem to Windows. (At the moment, I cannot remember why I used cygwin instead of the Windows 10 Linux subsystem.)\n\nEdit: Note this is also happening with the 'MyProgram.exe.config' file which more recently appears as 'MyProgram.exe.Config'."
