Question

This is the context: I’ve got to write a source for an intranet site which allows users to import a csv file into MySQL database.

This import is very massive that’s why I wrote a C# program.

This program creates some thread which reads some lines of my csv file.

These thread control, change type and insert my data into MySQL database with SQL like this:

insert into table1 (fields) values (dataline 1 ), (data line 25),...,(data line n);

This request exists for 9 tables.

This program can be used by everyone because the source code is dynamic : example to insert data I write a dictionary which contain my 9 tables with all fields, types and the CSV header of the import file (which contains some accent and symbol, I’ve to change it because I can’t put them into fieldname in my database).

This dictionary can be create only with a file called MAP.csv

Example:

table   /   field     /    type  /   header

table 1  /  field1_table1 /string  / hêàder

table 1   / field2_table1/ int    /  header1

table 2   / field1_table2/ date   /  hêàder2

table 1  /  field3_table1/ string  / hêàder3

My C# program works very well when I execute the program.exe

But when I call it with php with exec("programpath.exe parameter1 parameter2",return,otherreturn) function this program can’t work.

In fact when I try to access to externfile like config.xml , MAP.csv, otherfile.txt/csv/.. with my c# program. The execution stop and there is a windows error which says "program.exe stop its work" ( program.exe à cessé de fonctionner in French).

So I try to write my problem simply: when I try to access into a file with my c# program called by php, there is a window problem which stop the traitment.

EDIT :
I found the solution, I just have to do a cd c:/path_program/
In fact when I start my website the current folder is not c:/ but the folder in which Symfony starts…
Was just a beginner error.
