There is no difference in type of PDF between a PDF with all text and a PDF with all images and a PDF with both text and images. I assume image PDF means image in a PDF. When an image is extracted from a PDF it is the same as if the image was not in the PDF.

Probably your data is Unicode or UTF-8. I am not an expert on such things but you should ensure the data is being processed approriately. One possibility is the font being used. The data might be just fine but if you are not using a font that supports Unicode or UTF-8 (whatever is relevant) then you won't see it correctly. However the "\n" implies it is something else. That character is the carriage return, such as the Enter key in the keyboard. Note that Rich Text is not the same as HTML. The formats are very different.

Have you checked the file permissions for the database? I suppose that for a Trusted Connection that is not relevant. Can you open the database using that connection string in SSMS, or VS I suppose?

The best for me might be lousy for you and what might be best for you I might not like at all.

Since this is a class assignment, the best answers are ones that help you learn. You need to ask specific questions that you do not understand. The best way to get help is to show you have made a reasonable effort to figure it out.

.Net is a combination of many things. The GUI designers are more like VB 6 and VB prior to 6. .Net does not have the equivalent of the Document/View architecture built into it as it is in MFC. .Net does not support mixing languages using a linker as does unmanaged code does. Use of multiple languages by a .Net application requires that each language be a separate executable (DLL or the single exe file). Much of .Net is based on Java. The .Net intermediate language might be an evolution of the technology Microsoft had in the original Basic interpreter in DOS. The designer and original developer of C++ explains that C++ does not support the kind of feature (such as the .Net intermediate language) that provides the portability that Java and .Net languages provide.

There was a website with database models but the business does not exist now and the website went away. We can still get to the stuff using the Wayback Machine. Have a look at Industry Data Models in case it helps.

I know this is old but in case it helps anyone, look at [Eclipse](https://www.eclipse.org).

Yes. Probably programmers have gotten confused by the use of apostrophes for strings in many languages. And confusion like with the use of words can make communication difficult. A language must be understood by everyone using it.

Yes forcing them to have to keep track of these kind of stupid rules is a huge problem in the English language. This is one of many examples that can cause confusion.

I strongly agree that English needs extensive improvement with thinking and planning. Something new that happens because someone feels it could be an improvement could make things worse. Use of words for multiple purposes are more likely to add to the confusion. Use of got in this different manner adds to the confusion. An example of a change that does not add value is the use of the apostrophe symbol instead of the quotation symbol for quotes, as in: 'wrong' instead of "wrong" 'proper' instead of "proper" That change adds no value; it is more likely to cause confusion.

I do not think that Have you got a programming question would be correct. I think that simply Have a programming question? would be correct.

Note that there are about 30 other examples in that page where got is used for the past tense. Yes, I know many people say I've got and variations of that but very seldom do they say I have got. Instead of I have got people nearly always say I have. Got means something has been transferred in the past. Have means possession. In the context here, the question is asking if we have (possess) a question. I sure hope no one minds the proper use of have and I think some people (other than me) mind the use of got in this context.

No, it still says got instead of have in many places here. I assume you intend to imply that the misuse of got has been here for a long time.

Very many people are using got improperly. For example, Got a programming question is improper; Have a programming question is proper.

See [OS/360 and successors \- Wikipedia](https://en.wikipedia.org/wiki/OS/360\_and\_successors#MVT). There were processors and operating systems half a century ago that supported multiple tasks (threads). The idea was that many things, especially I/O, took time and if only one task executes then the processor is idle for a long period of time. Back then disk drives and tape drives were very slow.

I tried to download the demo project for the article CommandParser - A getopt() Inspired Command Line Parser for C# using LINQ but Windows Defender says it has a virus. I don't know anything more than that. The source is okay.

Looking in Wikipedia (which is not always reliable but is useful for this) multitasking was available beginning about 1964. Even back then, processors were faster than peripheral hardware so the benefits of multitasking was obvious. Not relevant to Microsoft, but I once saw a presentation for Artificial Intelligence programmers about a new way to design software. It was old stuff for other types of programmers. Microsoft's tendency to deliver things to the world is not always good; their focus on Basic instead of superior technology, such as Pascal, is unfortunate. If I had a choice of Basic or COBOL as they existed at the time, COBOL was far superior. If performance was the consideration, Pascal was explicitly designed to show that something better was possible that could perform equivalent to Basic. Most people do not realize how much of what Microsoft developed in their earlier years came from outside Microsoft, such as from IBM and Unix. The one innovation that Microsoft did help with could be dynamic linking. Unix did not have it at the time; I forget if OS/2 did but it probably did. As I mentioned previously, and in the context of UWP, I wonder how much of the async/await mess is unique to Microsoft.

I don't think I ever talked with Grace Hopper directly. I attended a presentation by her. She gave all the participants a nanosecond. I was in the Army. I also wish I had appreciated Grace Hopper back then. As for COBOL, it is more appropriate to say "financial" instead of "banking". However COBOL was used substantially by non-financial companies such as aircraft manufacturers. The engineering and manufacturing systems of aircraft such as the L-1011 and the F-22 Raptor ATF were all COBOL. So it is probably more appropriate to say "business" instead of "financial" and it is called Common Business-Oriented Language. You are right that it is neither scientific-oriented nor software-oriented (as in operating systems and compilers). The C language was designed to include software-oriented uses.

I should have returned to Grace Hopper's office sometime when she was there and told her I wanted more challenging work. I did not think about that back then but my life would have been different if I had done that. At the time I was working in the Pentagon but I had very, very little to do. As for COBOL, we need a language with similar requirements but improved with modern advances. I don't know what the current standard is but it is probably held back by COBOL's legacy. I think it would be interesting to design a language based on COBOL's design and used in internet servers like PHP. It could be and should be more professional than PHP.
