How to import data from one column of Excel to listbox using C#

独自空忆成欢 提交于 2019-12-02 11:13:00
I have an openFileDialog tool. I will choose a excel file from my computer and my programme read a column (for example A column) and write my listbox on GUI. How can i do it via OleDB? I am new at C#. If you explain detailed, I will be happy for that. Thank you for your help. In order to use the OLEDB provider successfully we have to consider a few points. The OLEDB provider for Excel 2003 files is different from the one used for Excel 2007/2010 files. So, the first thing we have to do is determining the Excel file format in order to select the correct provider. In the code example below I

How to import an Excel file into MySQL using ODBC in Java?

蓝咒 提交于 2019-12-02 07:36:59
I want to import an Excel file into a MySQL database using an ODBC driver. Does Java support this technique? If yes, please guide me on how to implement this. You can read an Excel file in Java using the Apache POI library: http://poi.apache.org/ There are some code samples on their howto page which will tell you how to read an Excel file: http://poi.apache.org/spreadsheet/how-to.html To store the data it would be better for you to use the JDBC driver for MySQL rather than ODBC since ODBC relies on native libraries. You can get the connector here: http://www.mysql.com/products/connector/ If

Importing from Excel - non-numeric values are ignored

I have code that imports from Excel sheets of a specified format. In one of the columns, most data is numeric, but non-numeric values are also present.

Generate table schema inspecting Excel(CSV) and import data

99封情书 提交于 2019-11-30 14:16:31
How would I go around creating a MYSQL table schema inspecting an Excel(or CSV) file. Are there any ready Python libraries for the task? Column headers would be sanitized to column names. Datatype would be estimated based on the contents of the spreadsheet column. When done, data would be loaded to the table. I have an Excel file of ~200 columns that I want to start normalizing. Use the xlrd module; start here . [Disclaimer: I'm the author]. xlrd classifies cells into text, number, date, boolean, error, blank, and empty. It distinguishes dates from numbers by inspecting the format associated

How can I skip first several lines of the Excel sheet?

痴心易碎 提交于 2019-11-29 17:02:54
Using openpyxl I tried to read from the fifth line for some files. The files' first four lines are the header. Then the main content has a different format from the header.
