            ANSWER

            Answered 2022-Mar-26 at 00:26

            You have (at least) three (somewhat) unrelated problems.

            Using the lexical scanner

            Your code stops after reading a single token because you only call yylex() once (and ignore what it returns). yylex() returns a single token every time you call it; if you want to scan the entire file, you need to call it in a loop. It will return 0 when it encounters the end of input.

            Understanding patterns

            The pattern \"[^\"\n]+|[\\n]+\" has an | in the middle; that operator matches either of the patterns which surround it. So you are matching \"[^\"\n]+ or [\\n]+\". The first one matches a single double quote, followed by any number of characters (but at least one), which cannot be a quote or a new line. So that matches "aryan banyal without the closing quote but including the open quote. The second half of the alternative would match any number of characters (again, at least one) all of which are either a backslash or the letter n, and then a single double quote.

            (I don't understand the thinking behind this pattern, and it is almost certainly not what you intended. Had you called yylex again after the match of "aryan banyal, the closing quote would not have been matched, because it would be the immediate next character, and the pattern insists that it be preceded by at least one backslash or n. (Maybe you intended that to be a newline, but there is not one of those either.)

            I think you probably wanted to match the entire quoted string, and then to keep only the part between the quotes. If you had written the pattern correctly, that's what it would have matched, and then you would need to remove the double quotes. I'll leave writing the correct pattern as an exercise. You might want to read the short description of Flex patterns in the Flex manual; you probably also have some information in your class notes.

            Selecting just a part of the match

            It's easy to remove the quote at the beginning of the token. All that requires is adding one to yytext. To get rid of the one at the end, you need to overwrite it with a \0, thereby terminating the string one character earlier. That's easy to do because Flex provides you with the length of the match in the variable yyleng. So you could set yytext[yyleng - 1] = '\0' and then call your symbol table function with yytext + 1.

            If the above paragraph did not make sense, you should review any introductory text on string processing in C. Remember that in C, a string is nothing but an array of single characters (small integers) terminated with a 0. That's makes some things very easy to do, and other things a bit painful (but never mysterious).

            SSIS package fails to process all rows with C# Script task when started with SQL Server Agent
            Asked 2022-Mar-07 at 16:58

            I have a requirement to build a SSIS package that sends HTML formatted emails and then saves the emails as tiff files. I have created a script task that processes the necessary records and then coverts the HTML code to the tiff. I have split the process into separate packages, the email send works fine the converting HTML to tiff is causing the issue.

            When running the package manually it will process all files without any issues. my test currently is about 315 files this needs to be able to process at least 1,000 when finished with the ability to send up to 10,000 at one time. The problem is when I set the package to execute using SQL Server Agent it stops at 207 files. The package is deployed to SQL Server 2019 in the SSIS Catalog

            What I have tried so far

            I started with the script being placed in a SSIS package and deployed to the server and calling the package from a step (works 99.999999% of the time with all packages) tried both 32 and 64 bit runtime. Never any error messages just Unexpected Termination when looking at the execution reports. When clicking in the catalog and executing package it will process all the files. The SQL Server Agent is using a proxy and I also created another proxy account with my admin credentials to test for any issues with the account.

            Created another package to call the package and used the Execute Package Task to call the first package, same result 207 files. Changed the execute Process task to an Execute SQL Task and tried the script that is created to manually start a package in the catalog 207 files. Tried executing the script from the command line both through the other SSIS package and the SQL Server Agent directly same results 207 files. If I try any of those methods directly outside SQL Server Agent the process runs no issues.

            I converted the script task to a console application and it works processing all the files. When calling the executable file from any method from the SQL Server Agent it once again stops at the 207 files.

            I have consulted with the companies DBA and Systems teams and they have not found anything that could be causing this error. There seems to be some type of limit that no matter the method of execution SQL Server Agent will not allow. I have mentioned looking at third-party applications but have been told no.

            I have included the code below that I have been able to piece together. I am a SQL developer so C# is outside my knowledge base. Is there a way to optimize the code so it only uses one thread or does a cleanup between each letter. There may be a need for this to create over ten thousand letters at certain times.

            Update

            I have replaced the code with the new updated code. The email and image creation are all included as this is what the final product must do. When sending the emails there is a primary and secondary email address and depending on what email address is used it will change what the body of the email contains. When looking at the code there is a section of try catch that sends to primary when indicated to and if that fails it send to secondary instead. I am guessing there is a much cleaner way of doing that section but this is my first program as I work in SQL for everything else.

            Thank You for all the suggestions and help.

            I have resolved the issue so it meets the needs of my project. There is probably a better solution but this does work. Using the code above I created an executable file and limited the result set to top 100. Created a ssis package with a For Loop that does a record count from the staging table and kicks off the executable file. I performed several tests and was able to exceed the 10,000 limit that was a requirement to the project.

            In Java Swing (using swingx) how to sort rows in one table in same order as another table
            Asked 2022-Feb-12 at 17:22

            I have a table with x num of rows, I have a second table with the same number of rows but different columns and metadata, they have different table models. but each row represents the same object (a song).

            I want to synchronize row sorting between the two tables so for example if I sort on column 2 of table 1 then rows of the table will be sorted in the same order. But currently, I just have sorted by matching sort keys so sort on the same column (but because different data get different results)

            Delete entire row if the same value is found in another cell on the same row
            Asked 2021-Nov-18 at 19:00

            First, I must mention that I am using Excel for Mac, so any code suggestions needs to work for a Mac using Office 365.

            I have a large dataset that has nine columns of names. I want to delete the entire row if the same name is in multiple columns in the same row

            Example dataset:

            So all of these rows would be deleted because:

            1. Jason appears twice in row 1
            2. Jason appears 3 times in row 2
            3. Jason appears 4 times in row 3
            4. Sam appears twice in row 4
            5. Fred appears 3 times in row 5

            So no matter how many times a name is repeated in the same row of data, I want to delete that entirerow.

            My code is below. This code works but it crashes with a large dataset. I know there has to be a faster, more efficient way to write this code so that it can handle a large dataset. Plus, my code is too repetitive. There has to be a way to make the code more simple. Anyway, here's the code.
