Hi,
I read the artical
http://www.codeproject.com/useritems/Excel_Connectivity.asp
Its nice and i need some change.
I want to read an excel stream from the Web Page and
has to capture rows and column data from that stream
without saving the stream as a file in the physical
disk.
In this artical, we have specified a file name in the
connection string.
Anybody can clarify this ?
Thanks,
Murthy.

Hello,
I am running an ASP.NET application that works perfectly on the localhost but when I try to load on the browser from the server, I have the following error:
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customerrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customerrors> tag should then have its "mode" attribute set to "Off".
I did all mentioned in the details section but am still getting same error.. can some one help? I have worked on this for days...

For ASP.NET, look at the RequiredFieldValidator[^] control.

I hadn't noticed that you had already asked this question earlier. Did you not like the responses you got? They looked pretty good to me.

Hi!
I created a class called HelperClass where I have a lot of methods that help me with situations like this one. Here goes the code of the method to provide an alert window:
public static void MsgBox(System.Web.UI.Page page,string msg)
{
msg = msg.Replace("'","\\'");
page.RegisterStartupScript("msg","alert('" + msg + "');");
}
I also have other methods, if you need them let me know. I also found some free online tutorials at www.KYNOU.com
I hope I helped.

All server controls have properties. You access a property's value using the syntax:
ServerControl.Property
The TextBox control has a Text property for retrieving or setting the text in the box. If your TextBox is named "MyTextBox", you would retrieve its value in C# this way:
string myText = MyTextBox.Text;
You might benifit from a look at the QuickStart tutorials on http://www.asp.net[^].

To get the value of a HtmlTextBox control from C# code behind, you have to convert the Control to a server control, not a web server control. just click on the control and select "Run as server control". set the ID propety in the preorties window.
or you can add 'id="UName" runat="server"' this snippet in the textbox tag in the HTML view.
example
initially your control looks like the below,
<input type="TextBox">
alter it to
<input type="TextBox" id="UName" runat="server">
know at the code behinde
you can use the below code to get the value
System.Web.UI.HtmlInputText txtName = new System.Web.UI.HtmlInputText();<br />
txtName = (System.Web.UI.HtmlInputText)this.FindConrol("UName");
now txtName.Value will give you the textbox value
hope this helps you
Cheer.

I have a windows app project that I need to create an installer for distribution. How do I do that? Do I need a third party software?
|

Your question doesn't seem to refer to ASP.NET. You may want to post questions like these instead to a language-specific board in the future.
That being said, you could use the VS.NET's Setup project type to create a windows installation application.
