.net - Reading Comma Delimited Text File to C# DataTable, columns get truncated to 255 characters -

-

We are importing from CSV to SQL To do this, we are reading the CSV file and have a temporary .txt file Are using the schema ini. (I'm still not sure why this temporary file is being written, but in this way the code currently works). From there, we are loading datatables via OLEDB using the following connection string (for ASCII files). 

  "Provider = Microsoft, J.A.L.D. 4.4; Data Source =" + Spat + "; Expanded Properties = \" Text; HDR = Yes; FMT = delimited \ "";

Our problem is that fields with more than 255 characters are cut off. I've read about this problem online and it seems that the text field is sorted by default in this way Go.

I set my registry settings in ImportMixedTypes = Majority type and TypeGuessRows = 0 in HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Jet \ 4.0 \ Engines \ Excel \ / Code>, hopefully mycolumns will no longer be interpreted as text. After doing this, the temporary TXT file is being written correctly from the CSV file, but when I DataAdapter.Fill , the resulting datatile has a small value.

column definition in question CommaDelimited # txt Notes 2 false 234 true 130 0 0

Any help would be appreciated. At this time, I am not interested in using any 3D party code to solve this problem, there should be a method built in the tool.

The table definition here is: 

   False & lt; / COLUMN_HASDEFAULT> & Lt; COLUMN_FLAGS & gt; 234 & lt; / COLUMN_FLAGS & gt; & Lt; IS_NULLABLE & gt; True & lt; / IS_NULLABLE & gt; & Lt; DATA_TYPE & gt; 130 & lt; / DATA_TYPE & gt; & Lt; CHARACTER_MAXIMUM_LENGTH & gt; 0 & lt; / CHARACTER_MAXIMUM_LENGTH & gt; & Lt; CHARACTER_OCTET_LENGTH & gt; 0 & lt; / CHARACTER_OCTET_LENGTH & gt; & Lt; / Column & gt;

Thanks,

Greg

I tried to edit schema.ini specified text with a width, and with Did not get help (it was set to the first memo)

[CommaDelimited.txt] format = CSVDelimited DecimalSymbol =. Call 1 = Notes Text width 5000

Jet database engine makes the memo field smaller, The process is called on the basis of memo: aggregation, de-duplicating, formatting, and so on.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
