There are no projects to bid for here. Are you talking about some other site?

You have to pass the <textboxname>.ClientID as an argument in the function
from where you are calling

ex..

onClick="show('<%TextBox1.ClientID%>');"

Excel Data to MSSQL thru ASP.Net

Hi Guys,

I already posted some of my questions about reading something from excel file, but there's no absolute answer yet.

Actually, what I am trying to do is to extract all the data from my excel sheet1 and save it into the MSSQL table.

The condition of my excel file is 5MB to 7MB in size with macro in it, and has 20 columns.

Do you think is it possible to transfer the excel data into the MSSQL2005 table?

I've been solving this almost a week already. I hope you could help me

Thank you

Import text file to MS Access, Asp.net(VB)

Hi I would appreciate any assistance with the above.
I am use to VBA in Access which is a 1 line code - docmd.tranfertext... to import information into an access database.

I am working with VB.net in ASP.net. I am new to this environment.
I already have a table tblcurrency. I want to update my table with text file C:\Textfile.txt
I will change the paths later - just want the code to work first

The error is:
Syntax error in INSERT INTO statement. - Microsoft JET Database Engine

My code is:
Dim cnn As OleDbConnection
Dim strSQL As String
Dim Debug As Diagnostics.Debug

cnn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source = c:\Inetpub\wwwroot\TestDB\DB\Bonus.mdb")
cnn.Open()

strSQL = "INSERT INTO [TblCurrency] (Country, Year) SELECT F1, F2 FROM[Text;HDR=NO;DATABASE=C:\;].[test.txt]"

Dim objCommand As New System.Data.OleDb.OleDbCommand(strSQL, cnn)
objCommand.CommandText = strSQL
objCommand.ExecuteNonQuery()
cnn.Close()

Thx

Rykie

VBscript and VB.NET are totally different. What you're dong here, just plain won't work. You want to read the text file in VB.NET, parse it, and then use that to write proper SQL for Access.

System.IO.File.ReadAllLines will read your file into a string array, that's a good place to start.

I am having a problem in my asp.net project.I have a form that has some anthem dropdowns which is data binded.I am opening a new page as popup and adding some data to the database.I wants the dropdown to update the added values when the popup is closed.I cant use

on child page because it destroys the values in the text boxes.

I can call a javascript function in the parent page like..

and the function in parent page as

function UpdateCity()

document.getElementById('<%=ddlCity.ClientID%>').Databind();

}

But i cant get the databind to work.Can anyone help me...Is there any other way to accomplish this..?

Starting an application on the server

Deques5-Sep-07 1:43

Is it really possible to start a program that resides in the server from a web application?

I am using following code:

<br />
using System.Diagnostics;<br />
<br />
Process startNotepad = new Process();<br />
startNotepad.StartInfo.FileName = "notepad.exe";<br />
<br />
startNotepad.StartInfo.UseShellExecute = true;<br />
startNotepad.StartInfo.CreateNoWindow = false;<br />
<br />
startNotepad.Start();

This works while debugging the page. I can see notepad start. But when I try it in a server I dont see Notepad, but I do see a process in task manager started

The owner the process started from your web application is ASPNET. ASPNET does not have an active desktop, thus, the process will run but will not display.

Does that mean I could run an application (.exe) in the background (say one without a user interface) that I upload to my server using this method? Say, for example, one that sends out emails to a list I upload... How about one that wipes the server hard-disk.. eek...

If ASPNET's access is more than its default access, you are opening up your web server to some nasty security issues. There are more secure ways of doing running a process.

I guess it has to be a security issue, am I right?

Re: Starting an application on the server

Yes, it can be a security issue. Also, you loose a lot of control of your application since you are running mulitple processes. Since your web application may have several user using your application at the same time, running several of the same local processes can be come a resource hog or cause some unforeseen conflicts. If a local process fails, how do you recover?

And if i pen the same website on other system with resoltuion of system set to 1024 then my website should get automatically adjusted to that resolution.

thanks,

harry

You can get the system display settings by using screen.width and screen.height, although I'm not sure if that's what you need.

There's also screen.availWidth and screen.availHeight, which are the available width and height.
