c# - ReadLine() vs Read() to Get CR and LF Efficiently? -

-

To set the line length of each line in many large text files with 100,000+ rows before importing, Using an SSIS package working on the program I will also check other values ​​in each line to verify that they are right to import into their database using SSIS. For example, I'm looking for a line length of 3,000 characters and a CR in 3001 and LF in 3002, so there are a total of 3002 characters in total.

When using ReadLine () it reads a CR or LF as the end of the line so that I can not check CR or LF characters. To determine whether the length is fine or not, I was just checking the line length of 3000. I just had to face an issue where the file 3001 had an LF in the situation but lost the CR. So readline () says that this 3000 Charlie Witch is correct, but it will fail in my SSIS package because it is missing a CR.

I've verified that once each character will reach 1, I can determine whether each row has a CR and LF but it looks unproductive, and when faced with some files If it does, then it is very disabled above the limit of 5000000 above. I will then need to add each letter to the string or use the Reebok () and convert a four array into a string so that I can see other values ​​in the line.

Do anyone have any ideas to check the line for CR and LF and without damaging unnecessary resources and without ending in a relatively timely way, other values ​​on a given line How to check

has verified that read () will reach 1 character at once and I can determine if each line has a CR and LF but it seems unproductive

Think about this: do you think that readLine () Is there a magic wand and do not need to read every character?

Just create your own read-miles line () Some have to read the letters, it does not matter if it's your code or Lib is I / O will be buffer by stream and Windows.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
