QUESTION
I am working with a file handling system that is to return a file to the user on prompt. The call goes to a endpoint MVC controller that calls a function in a helper class that returns a FileStream. The endpoint then returns the file with the ActionResult
File(FileStream, Mime.Type, FileName);
I am having issues in the helper class where I create and process the file.
My goals are:
1.Create the file
2.Write its contents
3.Run a third party program on the file (with a Process using a .exe file)
And to Log the results on most actions.
What I am trying to do is create a FileStream that creates the file and then pass the FileStream between methods to do different work like writing reading and running the 3rd party program. I am also using static file classes (System.IO.File) to logg to a logfile
Previously i just created the file and passed its path around and created new stream objects or used static classes to read/write to it but it felt kind of ugly. I feel using a object as a resource is more in line with object oriented programming.
Is my thinking here just wrong and working like this is just prone to errors?

Answered 2022-Apr-08 at 09:03fileStream.Flush();
using (StreamWriter fileWriter = new StreamWriter(fileStream)) //Crashes here File is in use by other process
There is really no need to flush the file here, since nothing is written yet. That flush is the only reason I can think of why creating the streamWriter would fail.
//the file disapears from directory when the streamWriter exits using scope
StreamWriter will take ownership of the stream, and dispose it when it is disposed. Since you asked for the file to be removed on close, this is expected behavior. If you want to opt out of this behavior you should use the constructor that takes a leaveopen parameter
System.IO.File.ReadAllText(file.Name)
Why are you reading what you just wrote? Just write the information to the log at the same time you write it to the file. You should be able to rely on the framework classes doing what they should do.
SignOrFormatFile(fileObject , file, signFile);
You may need to flush the file after it has been written. I'm unsure if streamwriter will flush when it is disposed. I would not be certain that this succeeds, it may depend on how the third party handles shared files. It is probably worth a try, but you may need to rewrite your method to close the file and then call the third party program.
return file;
Since the filestream is in a 'using' block, as it should, the file will be disposed. So your returned filestream object will be unusable. It is unclear what you intend to do with the result. I would have suggested returning a FileInfo object instead, but since you delete the file when it is closed, that would be valid either.

QUESTION
I have a table called licenses that holds all my users professional license numbers. There is a field, lic_type that holds the official letter code for the professional license, "PN", "RN", "RT", "APRN", "EO", etcetera. There is another column in the same licenses table, number, that holds the numeric portion of the full license information, 2261234, 1234567, etcetera, but the field is not INT it is varchar(18) due to need for some strings (see later in this question). I am NOT able to change the database structure or the type of the number column. Currently, when I concat these two fields together, it should give the full license designation.
For example - if lic_type is "RN" and number is "2676612", then when they are concatenated, they produce the correct license for the individual - RN2676612. However, the database I have received contains SOME entries in number column that contain the full license, i.e. RN2676612, instead of just numbers. Sometimes the letters are not even the right code. For example, the lic-type may be "PN", but they may have entered "LPN2261123", so that I cannot search for the entry in lic_type in the number column.
I need an MySQL query that will return ANY row where number contains any letters and at LEAST one number. I must allow full letter entries in number such as STUDENT or WAITING, but they will always have NO numbers, so, any entry in number that has a letter and a number is invalid and I need to correct. This allows me to bypass all letter numbers when pulling information from fully licensed customers.
Currently, I have tried the following query (in phpMyAdmin):

QUESTION
I have an IList that pretty much emulates the following table:
Code Year Type Value Active Paid ABC 2009 Lic NULL True 3.12 ABC 2009 Car Audi True 4.63 ABC 2010 Lic Learner True 5.41 ABC 2011 Lic Full True 7.82 ABC 2011 Car Honda True 5.19 ABC 2012 Lic Expired True 10.50 ABC 2013 Lic NULL True 15.71 XYZ 2009 Lic NULL True 4.63 XYZ 2010 Lic Full True 6.90 XYZ 2010 Car Mazda True 4.29 XYZ 2011 Lic Full True 9.73 XYZ 2011 Car Mazda True 9.17Each Code will have multiple Types, each with annual data. The amount of annual data for different Types for a single Code may differ.
I'm bringing it into a method as variable yv.
I have the following code to obtain the range of years of data, but I want to exclude those where Lic = NULL and the below returns all years in the DB. I'll later use the valid (Lic != NULL) years to do other calculations.
Also, advice on how to store the valid years so that they can be accessed by other methods doing other calculations that only need the valid years' data would also be appreciated. I'm out of my depth on this one.
...ANSWER
Answered 2022-Mar-07 at 08:22If I got it right for the first question you want to get the range of years every code has, without counting the lines where value == null, so for example "ABC" will have 2010-2011-2012, if that's the case you can try something like this:

Im making a controller that is to return a file based on a model in a database but im having issues with getting a prompt to download the file. The controller looks like this atm:
...ANSWER
Answered 2022-Jan-07 at 10:50Your 1st attempt (calling CreateFile from Index) isn't going to work, and it looks like you already understand why. Instead, doing a redirect to CreateFile would work, but then the file download will be the ultimate response of the call that was made to Index, and no new View will be shown.
The 2nd attempt doesn't work because a download only "happens" if the request was done by the browser window. When using $.ajax it's a XMLHttpRequest object that makes the request, it will receive the data and then it is up to you to extract the data and e.g. turn it into a Blob for download - not really easy or convenient.
A much easier solution would be to do this:

I am trying to replicate some diagrams that I made using Microsoft Visio, using the tikz package in LaTeX. The basic diagrams are relatively easy to build, but when it comes to add more than two nodes next to each other, it gets quite tricky... I can't seem to find any documentation that justifies my needs to center and align the nodes like I've done in Visio.
These are the MS Visio diagrams:

/home/MY_USER/.../sysroots-uninative/x86_64-linux/lib/libc.so.6: version 'GLIBC_2.32' not found (required by /lib64/libgomp.so.1)
You are mixing system libgomp.so.1 with sysroot libc.so.6 -- this will never end well. You probably need to build libgomp.so.1 in the sysroot as well.
And if I run
/lib/libc.so.6, I get:
That is irrelevant -- you link isn't failing with that library, but with the sysroot one.
If you run /home/MY_USER/path/Project/xilinx-zc702-2018.2/build/tmp/sysroots-uninative/x86_64-linux/lib/libc.so.6, you'll see that it is in fact too old (older than 2.32).
