excel - How to avoid OLEDB converting "."s into "#"s in column names? -

-

i'm using ace oledb driver read excel 2007 spreadsheet, , i'm finding '.' character in column names converted '#' character. example, if have following in spreadsheet:

name        amt. due        due date andrew      12.50           4/1/2010 brian       20.00           4/12/2010 charlie     1000.00         6/30/2010

the name of second column reported "amt# due" when read following code:

oledbconnection connection = new oledbconnection(     "provider=microsoft.ace.oledb.12.0; data source=myfile.xlsx; " +     "extended properties=\"excel 12.0 xml;hdr=yes;fmt=delimited;imex=1\""); olddbcommand command = new oledbcommand("select * mytable", connection); oledbreader datareader = command.executereader(); system.console.writeline(datareader.getname(1));

i've read through documentation can find , haven't found mentions happen. has run before? there way fix behavior?

see oledbadapter excel qa posted via stack overflow.

i made .xlsx workbook in excel data, , changed oledbconnection , read in data fine. 

string sql = "select f1, f2, f3 [sheet1$] f1 not null";  oledbconnection connection = new oledbconnection("provider=microsoft.ace.oledb.12.0;data source=" + prmpathexcelfile + @";extended properties=""excel 12.0;imex=1;hdr=no;typeguessrows=0;importmixedtypes=text""");

writing data console:

name  amt. due  due date andrew  12.50  4/1/2010 brian  20.00  4/12/2010

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
