Hi,
I am working in a Asp.Net Project in which i have to import an Excel sheet datas into a mysql database table and then i want to retrieve those datas into my dotnet application. pls note that i don't use any datagrid in my application. i just designed tables in my Form and get datas in text boxes. i'm new in using mysql database and i already worked in sql server. in sql we have import option and i don't find any of that option in mysql. i'm totally confused in how to import those datas into my database as there are some 50 rows in my excel sheet. I heard that we can extract those datas to database using C# code. pls provide me with a proper solution as i'm new to this concept and i'm struggling with this for the past 3 days(pls note that i don't need any tool to be used for exporting datas as no such tools will be provided for me).
Thanks in Advance
Vijay.

Dim fs As New WebClient

Check ASP.NET is having write permission on c:\srcfile ? Try server.mappath for the server directory

First get the files in that directory using
System.IO.Directory.GetFiles
The above line will return all the files present in the directory as a string array.

Use webclient class. It is having upload method. Start a loop till end of the above string array and upload each file using webclient method in the loop. Finally dispose webclient object

I need the list of client side files for the selected folder.
For eg, if user choose D:\Test, my web application needs to upload all files in that client folder to web path.
If we use system.io.directory.getfiles - it searches on server and cause exception as "could't find the path"..
Is there any way to get all files on client machine and upload to server machine.
Be simple and Be sample.

Upto my knowledge there is no method to do this using server side scripting. Because this will break the security system. If a server side script can list out the files in your directory then what is the security for your files ?

hi the below was my attempt of trying to make a new browser pop up when a button is clicked with java scipt
although it compiles it doest work instead of poping up another browser it just redirect to inself couls some1 help me see if i did anyhting wrong pls
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %><br />
<br />
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><br />
<script type="text/javascript"><br />
function OpenWindow()<br />
{<br />
window.open("Default.aspx", "_blank");<br />
<br />
}</script><br />
<html xmlns="http://www.w3.org/1999/xhtml" ><br />
<head runat="server"><br />
<title>Untitled Page</title><br />
</head><br />
<body><br />
<form id="form1" runat="server"><br />
<div><br />
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click1" /></div><br />
</form><br />
</body><br />
</html><br />
<br />
<br />
<br />
the code behind file in the form load<br />
<br />
<br />
Button1.Attributes.Add("Onclick", "<script>OpenWindow();</script>");
|
|
|
|
|
Try this, in your button click event (or even in its open function) add
Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
' Do some other processing...
Dim sb As New StringBuilder()
sb.Append("<script>")
sb.Append("window.open('http:
sb.Append("</scri");
sb.Append("pt>")
Page.RegisterStartupScript("test", sb.ToString())
End Sub
Then in your button
<asp:Button id="Button1" onclick="Button1_Click" runat="server" text="Go!"></asp:Button>
Make sure you add
Imports System.Text
To the top of your code behind as this uses the StringBuilder Class

}

No. StringBuffer is a Java class. It's StringBuilder both in VB.NET and C#.

use the following statement in your javascript
window.open("default.aspx","popupwindow","width=600,height=50px");

Why do you do a postback to call the Javascript? Do it all in the browser:
<input type="button" value="Button" onclick="OpenWindow();" />
