It's taking more than 15 minutes to search for Library entry.can anybody suggest how i can remove slowness of the application?

Big PBLs mean slow searches. Segregate your objects. Many people separate by object type. If you are in a hurry then this will work in a pinch. I work with huge applications. I organize PBLs by application function. This can also improve your compile time.
Back up your PBLs then optimize them. In the library painter (shift-F10) right click on the PBL and choose Optimize.
Our application has libraries that never change like the PowerBuilder Foundation Class PBLs. You can build runtime libraries (PBD) for them, then in your library list, change .PBL to .PBD. If you need to change an object in one of your "static" libraries, just change .PBD back to .PBL in your library list.
I export my objects to a folder and use my favorite text search tool. Windows search will also work on exported objects. I can search 7200 objects in less than 15 seconds.
Export all source file and search them by a modern text editor.
Like vscode or notepad++

I have seen Use a single source file for many QtDesigner forms, which is the gist of my question also, - but it simply recommends:
My advice is to use it as Qt way. Use seperate classes and seperate files for each form. This approach is better.
However, I would like to specifically know - is it possible at all to define multiple forms (say, a "Main Window" and a "Dialog with Buttons Bottom") in a single .ui file, and work with them in QtDesigner?
Basically, for an application of mine, I use QtDesigner .ui file to design the MainWindow, and load that from Python (PyQt5) - and it works great. Now, I'd just like to add a window dialog raised on a click of a button, and I'd also like to use QtDesigner for it, but I wouldn't want to maintain two .ui files. I'd imagine, once such an .ui file (with multiple form definitions) would be loaded in Python, the Python code would just set all forms other than QMainWindow to hidden, and then manage when they are shown appropriately.
(I use QtDesigner on and off, so I do not know it very well - however I recall there was some stuff that QtDesigner couldn't do from the UI, but one could do manually in the .ui file, and after such changes, QtDesigner could still deal with them. So, if there is a way to do this - even if it is not fully supported in the QtDesigner UI - I'd love to know about it, or have a definitive answer that it is not doable).
tl;dr
No, you cannot.
Why not?
UI files are intended for individual widgets (it doesn't matter whether they are intended as top level windows or not) and their possible children.
While I can understand your request, it seems more related to a "project" concept than an UI one. That's not the intent of Designer, which cannot imagine the possible extent of your project; and even if that was the case, it wouldn't be very practical: what if your project could potentially have hundreds of windows? Suppose that you have a main window, open your program, but then you decide to close it: your program would be loading hundreds of windows, but use none of them, causing an unnecessary overhead in the program loading.
The concept is similar to the modularization of OOP: not only you just "load" what you actually need, but you also should "split" the project in different files (modules, not unlike python modules) for better maintenance , reusability and overview. What if you want to have two separate "main" UI files for some reason, and, coincidentally, they use a similar dialog? You should copy that dialog every time, and if at some point you forget that step, you might even cause your program to crash as it's trying to access objects that don't exist or have been just slightly renamed.
Furthermore, some interfaces can be really complex, and automatically loading them at startup would be pointless: if you're using the uic module, you're requiring unnecessary parsing of the whole xml tree of the UI, and that would be for every time a new instance for a window from that file is required.
Maybe, someday, developers at Qt will decide to allow "projects" in Designer (which is probably what Qt Creator does, but I've never used it), but ui files will still be individual, as they should.
So, don't worry too much, it's more a question of habit and a slightly annoying aspect: if your project is well conceived, and you also properly name your files, it won't be a major problem and it will have its benefits anyway (even if you don't consider them as you could).
PS: yes, UI files are XML files and can be edited; you could even create/edit an UI file and do things Designer couldn't. But that's just an "unexpected feature" (or smart hack), for which you can never be always sure about the outcome. In future (or just different) versions the parser could be[come] more strict, with the result that your UI becomes completely unusable. That's not unlike editing pyuic files: the programs that use them expect a known behavior (the XML output of Designer), and common, accepted usage. As the recent pyuic file headers (which, I'd like to mark, was added after a personal suggestion of mine) report: "Do not edit this file unless you know what you are doing" ;-)
I've been successful in using form.location.resx files to localize the strings associated with form controls. However, I don't see how to (safely!) add strings to the .resx file(s) and then access them for such things as message boxes.
If I try to add a string to the .resx file using Visual Studio (2017), I get a warning dialog pop-up telling me that this could corrupt the "project item" (form) or my changes could be lost if I change the associated form.
Also, if I use this method, would I need to manually add my strings to each language file separately?
Alternatively, I could create a bunch of Labels to the form with visible=false and then edit their strings in the .resx files and use something like:
msgbox(LabelSampleMessage.text,MsgBoxStyle.Information,LabelSampleMessage2.text)
But that seems like it would be massively inefficient.
For Windows Forms, the best way to do this is to go into the Designer and set the Language property on the form. This will create a formName.Designer.languagecode.resx file for you. Then you just edit the Text properties of the controls. The changes will go to the resx file for the language you're editing. You can even have different layout and control spacing for each language (useful if a label is short in English but translates to something long in German).
For MessageBox messages, you do the same thing with the Resources.resx file. Just put all the messages in your Resources and duplicate the resx file for each language. Then use the Resource editor to translate the message in the other languages. You can then look up the message using My.Resources.Default.SomeMessageKey
#David: Note that I'm the author of a commercial ".resx" localization program for VS (in the interest of full disclosure). Yes, dwilliss is correct, though the names he used are a little off. For Windows forms, you can't manually update the ".resx" files yourself (directly), hence the warning from VS (don't know why they did things this way - go figure). You won't get that warning for strings you put in "Resources.resx" however. Just manually add "Resources.[LangCode].resx" and update it on your own. You have to add the keys yourself (again, no warnings). You can then simply access each string via the static properties seen in the "code-behind" file "Resources.Designer.cs" (one static property exists for each string you add). These are what MSFT calls "strongly typed" resources. If you access, say, "YourApp.Properties.Resources.SomeMessage" for instance (from "Resources.Designer.cs"), it will be returned in whatever language is currently set in "System.Threading.Thread.CurrentThread.CurrentUICulture" (assuming that language's satellite assembly is installed of course). This is all a pain and highly error-prone for other reasons as well, hence the reason I wrote my program (shameless plug but MSFT's way does work, though it's very primitive for handling translation in general - a professional organization relying on an external translator will save a lot of problems and $ in the long run by using a 3rd-party translation program, not mine necessarily though it would be my tool of choice of course, but anything is better than handling it manually).
Let say my iOS app already have translation localizatible.strings for Japanese. Say "Continue" = "続ける";
However, I've added new NSLocalization additions to my code but I want to use genstrings to get all new NSLocalizations without having to merge them manually.
Is there any way to do that?
There are tools that manage localization and that automatically make updates to translations based on changes to the base language (and helping the translator make the necessary changes only to whatever has been changed).
For example www.gengo.com has a free online tool called Strings (which I haven't tried yet). There are also desktop apps that look very good, such as Localization Manager as part of Localization Suite http://www.loc-suite.org/ (which I haven't tried properly yet either).
Localization agencies may have their own tools, too.
These tools are a must if you do a lot of updates and have several languages but for smaller projects, they can take a bit too much getting used to. For an occasional task or a small project with few languages, manually merging the changes of your base language localizable.strings files to your translated localizable.strings files might be quicker though.
There's a program called PPStream which is currently only available in Chinese, it allows for access to a myriad of ad-supported movies and TV series. The problems is that it is in Chinese and menus are indecipherable.
Is it possible to hook into the part of Mac OS's API that puts text on the screen so that it routes it through a wordlist first, translating the text into English? Would the API hook be able to differentiate the different applications calling the API?
I have no experience at all with Mac APIs, just pondering on if this is worth pursuing or not.
Thanks.
Edit: The reason I would like to do this at API level is that I need to dynamically dispatch HTTP queries with a list of strings to be translated (movie titles Chinese -> English), and the edit-the-i18n-file approach wouldn't do. Any other suggestions?
I haven't downloaded, installed or run PPStream myself so I'm speaking "out of my rear end" in a sense, but there are a number of ways to localize an app. But you really need to have access to the raw, uncompiled code and project to do it correctly.
The three most likely ways the string resources are saved are these:
1)
The app may have a strings file from which it fetches the strings to be displayed in the interface.
You may be able to make a copy of this strings file and set it to English or whatever language you choose.
2)
The strings may be baked into the code itself. This is generally a NO NO for commercial grade MacOS & iOS apps, but lazy and/or inexperienced developers can do this especially if they don't think their app will ever be used in other languages.
3)
The most likely set up is that there will be a folder hidden in the application package, inside the "Resources" folder, that has named like "en.lproj" or "English.lproj" or "de.lproj" or "zh_CN.lproj" or "zh_TW.lproj" (these last two are especially likely if this is only in Chinese).
Inside those folders will be localized XIB (or older NIB) files. And if you make a copy of this folder and then modify the newly made copy to add your new language.
Options 1 & 3 are ones you might be able to copy and then modify, but then again it might not work (especially these days when there's code & app signing). I've never tried this without an accompanying project, so if you have success, you should comment your question and/or this answer and let us know.
I want to read an existing PDF file, get not only the text, but also the format information like: Font (Bold, Italic...), and paragraphs... Is there an code library for doing this, is it open source or commercial?
I am on Windows and favor C# libraries, but C/C++ is also acceptable.
I can very much recommend
pdflib (http://www.pdflib.com/).
Its commercial, but it also has a lite version which you can use for free privately. It contains very muach functionality and is available for all plattforms.
I'd echo Mr. Meyers on this. There appear to be a number of them; search for "pdf parser library" (plus your language) in your favorite search engine.
A few top hits:
http://www.lowagie.com/iText/
http://metacpan.org/pod/PDF::Parse
http://podofo.sourceforge.net/
http://www.vicman.net/download/13733/ (several for .NET)
Note that if you're wanting to edit an existing PDF, you might want to read this:

The Pdfium.Net SDK also can help you. Via this API you can get access to a collection of text, images and other objects and ther properties.
Please note I work at the company who develop this API.
