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. Smile | :)

I have tried webclient class uploadfile method to upload files to server as,

Dim fs As New WebClient
Dim retValue As Byte()
retValue = fs.UploadFile("http:\\<somesrc>\srcfile", "POST", "c:\srcfile")

I got exception as,
The remote server returned an error: (401) Unauthorized.

Let me know how to solve this error, and upload files to server using webclient.

Be simple and Be sample.

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

Hi,
I need to upload all files from the given client's physical folder path to server path.

How do I upload all files to web server path without using "file" type.

Thanks and Regards

If you want something you never had,
do something you have never done!

User can be able to choose only the folder, not the files.

Be simple and Be sample.

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

printf("Navaneeth!!")

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,
I need user on client machine to select path from that machine (local folder only). On Upload, my web application needs to get all the files in that folder and upload it to fixed server path.

All I need is to get files for the selected client path.

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 />

<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://msdn.microsoft.com', '', '');")
	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

my code behidn file is c# though >.<

Then convert the code to C#

void Button1_Click(object sender, EventArgs e)
  {
      // Do some other processing...

      StringBuilder sb = new StringBuilder();
      sb.Append("<script>");
      sb.Append("window.open('http://msdn.microsoft.com', '', '');");
      sb.Append("</scri");
      sb.Append("pt>");

      Page.RegisterStartupScript("test", sb.ToString());
  }

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