"extract image from image",
"Is it possible to extract an image from a jpeg, png or tiff file? NOT PDF! Suppose I have a file containing both text and images in jpeg format (so it's basically a picture); I want to be able to extract the image only programmatically (preferably using Java). If anyone knows useful libraries please let me know. I have already tried AspriseOCR and tesseract-ocr, they have been successful at extracting text only (obviously).\nThank you."

"SCCM 2012 Application Deployment scripting issues, any ideas?",
"I had no problems with SCCM 2007 scripting application deployments, but SCCM 2012 has me pulling my hair out and I have very little left.\nWe tend to have heavily scripted installs and most of the time the installs fail in SCCM 2012, the latest failure is symantec enterprise vault, I wrote a script that would check the main DLL plugin version and use the correct uninstall string to remove the previous version, before installing the latest version.\n\nmy script is very simple and works fine outside of SCCM, but inside SCCM it fails.\n\nIf I recreate the application as a MSI deployment and use the MSI file then it installs fine, so SCCM is working correctly to the client. The uninstall that SCCM puts in from the MSI failed, but that is covered below in the example. I have checked all the client side log files and can not find any issue.\n\nI even return the successfull install return code 1707 and 0 at the end of the script to try and get SCCM to make it a success.\nI have written the script first in VB.net as a console service app and then rewrote it in vb script. both scripts fail. I used to use AutoIT to write scripts in the past, but that too was failing, so I thought I would switch to something more microsoft.\n\nFor detection I use the windows installer selection and point to the msi file where it picks up the product code.\n\ndeployment type is script.\n\nThe only thing I can think of is SCCM 2012 does not like the sleeps that are in the scripts.\n\nor it just does not like scripts. :-(\n\nThe MSI uninstall failed, because it needed to run as administrator, as you can see from the script below, I run as administrator and this works outside SCCM, but not in SCCM. the install uses pretty much the same code but more logic and many more uninstall strings.\n\neven the uninstall fails and here is how simple the uninstall script is;\n\nSet WshShell = WScript.CreateObject(\"WScript.Shell\")\nIf WScript.Arguments.length = 0 Then\n Set ObjShell = CreateObject(\"Shell.Application\")\n ObjShell.ShellExecute \"wscript.exe\", \"\"\"\" & \n WScript.ScriptFullName & \"\"\"\" & \"RunAsAdministrator\", , \"runas\", 1\n Else\nend if\n\nSet objShell = CreateObject(\"WScript.Shell\")\nSet objExec = objShell.Exec(\"MsiExec.exe /x{ADEBB592-4986-4FD1-868C-D59DB32F0BC2} /q\")\n\nWScript.Sleep 8000\nreturnValue = 1707\nWScript.Quit(returnValue)"

So the choices made in the design and development were something I am not 100% sure on and so I cannot comment on the reasoning behind why things are set up how they are. I also looked through all of the questions on Apache-Cayenne tag and could not find something that addresses this. Please inform me if I'm mistaken on that and I'll gladly check it out.\n\nEssentially, we have a table that has a plethora of columns and I only want a few of those columns to be loaded (otherwise there is way too much unnecessary data being queried and it takes the page a lot longer to load).\n\nAs an example to keep it generic, let's say I have a table with object that have 10 columns. I want only 3 of the columns. So in my code I would have this:\n\npublic List<objectToQuery> getSpecificColumns() {\n\nObjectContext context = getNewContext();\n\nSQLTemplate select = new SQLTemplate(objectToQuery.class, \"select column1, column2, column3 from table\");\n\nList<objectToQuery> results = context.performQuery(select);\n\nreturn results;\n}\n\n\nAnd when I run this, it works and returns the proper amount of rows. However, when I try to interact with and retrieve data, it will run individual queries on every row that includes all columns anyways.\n\nSo for examle if on the page that gets the results I would have:\n\nobject.getColumn1();\n\n\nIt will run a query on the object for all of the columns... Why does this happen and is there any way to accomplish what I'm trying to do?\n\nMany thanks,\n-R"

"Using ajax and jQuery to execute some PHP code",
"EDIT: solved. Was a simple mistake. The PHP file needed one of those \"?field=value\" things in the URL, and that's what needed to be in the data section. I needed to feed through the value of the input field to the PHP file, since when using Ajax, the URL does not change. \n\n\n\nThree files:\n test.html\n test.php\n test.js\n\nSo when a user clicks a button in test.html, it will execute the php code in test.php\n\n<form method=\"GET\" action=\"test.php\" id=\"addData\">\n\n\nThat works fine. The PHP retireves some information from another website and stores them in variables and then sends them to my database. Everything works fine. What I want to do now is make this process occur in the background.\nI have been researching the jQuery ajax call, and there is a 'data' field where you need to enter data to 'send'. This is where I got confused. My data is all handled in the PHP file and my javascript file has no access to that data. So...what goes in the data field?\n\n $(document).ready(function(){\n $(\"#addData\").submit(function(e){\n e.preventDefault();\n $.ajax\n ({\n type: 'POST',\n url: 'test.php',\n data: ?????????????????????????????\n success.........\n })\n });\n });\n\n\nSo when they submit the form, I want the PHP to execute and the data sent to the database. All the 'data' is taken care of in the PHP file and the 'sending to the database' is also handled in the PHP file. So what do I put in the ajax 'data' field ??"

"Safe string copying over DLL boundaries",
"I am trying to make a DLL that exposes a certain API and thus wanted to implement a safe way to copy strings over the DLL boundaries. The DLL implementation is very straight forward - all the functions that return string values take two arguments - char* and size_t&. If the size is big enough I memcpy the contents of the string from within the DLL to the given pointer, set the size to the actual one and return a successful return code. If it is not I set the size to what it should be and return an error code. The DLL side is very straightforward.\n\nNow what is more complicated - how to make a nice template function which given a pointer to some function from the DLL would do all the correct manipulations to fill out an instance of std::string. This is what I came down to:\n\ntemplate<typename I>\nCErrorCode GetStringValue(const I& Instance, CErrorCode(I::*pMethod)(char*, size_t&) const, std::string& sValue)\n{\n std::string sTemporaryValue;\n size_t nValueLength = sTemporaryValue.capacity();\n sTemporaryValue.resize(nValueLength);\n do\n {\n auto eErrorCode = (Instance.*pMethod)(const_cast<char*>(sTemporaryValue.c_str()), nValueLength);\n if (eErrorCode == CErrorCode::BufferTooSmall)\n {\n sTemporaryValue.resize(nValueLength);\n }\n else\n {\n if (eErrorCode == CErrorCode::NoError)\n {\n sTemporaryValue.resize(nValueLength);\n sValue = std::move(sTemporaryValue);\n }\n return eErrorCode;\n }\n } \n while (true);\n}\n\n\nSo I did the initial resize because I can't do that after the first call (since then it would erase the content, since the string is initially empty). But resize fills the string with zero characters, which kind of upsets me (I mean I know I am going to be doing the filling myself anyway). And then I need the resize even after a successful run since if the length was actually smaller I need to resize down. Any suggestions if this can be done I a nicer way?"

"Get a column to represent data from another table",

I've completed a jsf web app that utlizes hibernate and infinispan with Tomcat7 and tomcat-jdbc-pool as the connection pool provider. \n\nIt is being deployed to a Linode cluster w/ 2 nodes -- one database server and one production server. \n\nI can run the app on my local environment using the exact same copy of Tomcat7 (I literally tarred the tomcat directory and promoted it to the server to debug this error) -- even when connected to the live database instance. Everything runs fine.\n\nWhen I attempt to run the application from the production server I get a MySQLIO error:\n\n\n Caused by: java.net.ConnectException:\n Connection refused\n\n\nLooking further up in the logs i see:\n\n\n The last packet sent successfully to\n the server was 1 milliseconds ago.

I have the app moded w/ a dev and live mode and the connection pool was reading the dev mode this whole time. What really made it confusing is that the sessionfactory was moded to live so it would actually reach the live database and initialize a connection when it started up so i could see it connecting (and running meta data queries in the mysql log), but when it actually went to grab a connection from infinispan it blew up.

"Scripted method to find and kill process using a specific dll",
"I need your help to make a script to be used to alleviate symptoms of an issue while we dig into it and find the cause.\n\nDescription of issue: We have a problem where a dll gets locked and this stops IIS from handling requests. There are a couple of dll's that could be the issue. We mapped them as exceptions for Windows Defender but still the issue occurs.\n\nWe can detect the issue by writing a script to periodically access the website which will stall if the issue is happening.\n\nThis is on Windows 2016 Server.\n\nRequirement: Clearly a long term fix is needed and we are working on this. Whilst we find that fix, we are seeking a way to find the process that is using a dll and kill that process. \n\nSysInternals ProcessExplorer can identify the process that is accessing a dll file (this is the binoculars feature). And once we know which process then we can also kill that process in ProcessExplorer. \n\nThe ideal solution would be a script that searches for processes using a specified dll name and then kills them. I guess we can use command line utilities of sysinternals but don't know where to start.\n\nNotes: Ideally we will fix the issue but it is ongoing so we want to alleviate the symptoms. Some of you are going to maybe suggest fixing the issue and if you have a solution then send it in. In the mean time here are some questions that may get asked... What causes the issue - if we knew that...! The issue seems to occur after the Windows Defender signature update runs. It 'feels' like when Windows Defender restarts to load the new threat signatures, the dll that is in memory is somehow seen as a threat. Could it be a bone fide threat - no because we scanned it manually and it comes up clean."

"Multiple simultanous animations, simulation of 'animate' easing and one 'step' call for a jQuery collection",
"Here is the problem, I've got a tree structure of html blocks, global container is of a fixed width(X) and height(Y). When i click one of the blocks on a level, all other blocks shrink to some size, while the clicked one gets enlarged to the leftover space, and the sublevels show up on it's place.\n\nFor all the shrinking i'm using default animate function with easing effect, when shrinking 1 level, to avoid enlargement bugs i have to do something like this:\n\n$tabs.not($obj).animate({height:32<<$obj.getVerUp().length+\"px\"},{duration:300,\n step:function() {\n $obj.height(function(){\n var sum = 0;\n $tabs.not($obj).each(function(){\n sum += $(this).height();\n });\n return $obj.getCont().height()-sum+\"px\";\n });\n }\n});\n\n\n$tabs are all the tabs of current level, $obj - is the one tab that i want to enlarge\n\nThe main problem is:\nWhen i open up a tab that is on a deep level, i have to animate all the tabs of higher levels to shrink a little bit more, thus the $obj X and Y would change, so the current animation has to use new values, but if i call 3 different animations on different levels i'm bound to get a bug, when one of the animations on a deeper level finishes 1 step earlier, while the one on the level above, would enlarge the object by 5-10 more pixels and that space wouldn't be used up.\n\nThe second problem is that there has to be about 50 object animating with easing at the same time, which is a little bit overkill.\n\nAnd the last problem is when i call step callback on animation as shown above, i have a strange feeling that it calls the step separately for each animation of the $tabs collection, while i need 1 step for all the tabs in the list (to avoid unnecessary scripts)\n\nThere might be some other way to fix all that, but i have yet to discover all jQuery functions, so from what i see the only way is to simulate easing, and do everything in one single animation.\n\nI don't really want to use setInterval and determining when do i need to clear it plus calculating each of the easing values, if there is a simple way doing it.\n\nDoes jQuery has some sort of empty animation easing, e.g. \n\n$().css(\"height\":starth+\"px\").animate({height:endh},{duration:300,\n step:function(fn) {\n\n // all the animation actions here via fn end value\n }\n});\n\n\nThanks in advance.\n\n\n\nWhat I need - is not a completely working solution in code, just some enlightenment in those subjects:\n\n\nIs there a legal way to call one step function for a collection of animated elements, or, maybe, it does call step once when I use one .animate on collection.\nI'd be really appreciated if someone would shed some light over how does jquery handle multiple .animate, would they be used in one global function that works on .setInterval? or would they be having massive number of those .setIntervals that are equivalent to setTimeout (which most browsers can't handle in large amounts);\nIs there a way to simulate 'animate' easing, some function name maybe, or a special trick to achieve that (the only thing I see is a hidden element or 'window' property to change maybe)\n\n\nOr some directed pushes with functions I should study, that could help me achieve my goals"

"How do I include an SDK routine in VB6?",
"I am modifying some old VB6 code and there are a number of calls to a subroutine called SDKPress(Index as integer, PressStatus as Integer, PressX as double, PressY as double, PressDataX as double, PressDataY as double).\n(This routine returns the position of the mouse click and Index returns which graph on a form the mouse is in.)\nSince there is no code for this in the project, I assume it is from some Windows software development kit. However, there is no trace of it on the development PC. just an SDK directory in the VisualBasic directory containing winsdk_web.exe.\nI cannot call that subroutine from another project. Where does the subroutine live? Where can I find documentation on it? How can I get it in a form where I can use it on another project?"

"Recall window load event - javascript",

However for the second piece of content, the $(window).on(\"load\") event never fires.\n\nI have a hunch that this event is not allowed to be invoked a second time, or maybe it is unbound after being called?\n\nI tried triggering / invoking the method but to no avail.\n\nif((window.onload) === null)\n{\n $(window).on(\"load\", function() {\n console.log(\"$(window).on('load') called\");\n $(\".content\").toggleClass(\"hidden\", false);\n $(\".loader\").toggleClass(\"hidden\", true);\n });\n}\nelse\n{\n $(window).trigger(\"load\");\n}\n\n\nAlso, I assure everyone that it isn't the content being loaded, because if I replace $(window).on(\"load\") with $(document).ready() it works fine.

"How to write data in specified format into a binary file with Perl?",
"this might be quite a newbie question, but i need to process a certain text file and dump its content into a binary file and i do not know how - i decided to use perl, but my perl skills are quite low. I probably should have written this in C++, but this seem like a nice and easy task for perl, so why not learn something new? ;) The text file has thousands of lines in this format:\n\n2A02FC42 4\n\nYou can look at it as a hexadecimal number (the length is ALWAYS 8) and a regular number. Now i need to dump all the lines into a binary file in this format (it should look like this when viewed with a hex editor):\n\n42FC022A00000004\n\nMore examples so it is clear:\n\n70726F67 36 -> 676F727000000024 \n6A656374 471 -> 7463656A000001D7 \n\nThe part of parsing the input file is easy, but i'm stuck on the second part, where i should write this into a binary file. I have no idea how to format the data in this way or even how to output things in binary mode.
