Hello,
I have created a website in ASP.net 2.0 and uploaded it to the webserver. The following error message is displayed.
Compiler Error Message: CS0246: The type or namespace name 'Utilities' could not be found (are you missing a using directive or an assembly reference?)
where utilities.cs is a class file placed in APP_CODE folder in the same namespace as the website.
The site is running fine on the local server.
The web server is also unable to load the code behind files.
while everything seems to be fine on the local system.
Now i came to know that Framework 1.1 is installed on the web server. Could this be due to version problem??
i am able to run the pages on the webserver without calling the class.?
Could anybody please suggest me a solution.
thanks,
sangita

If your code is built for framework 2.0 it will not work on framework 1.1.

Hi,
i want to read the contents of the Word or excel file into my aspx page may be in a container if you say.
I have tried by using Response.contenttyp but it shows a dialog box asking if i want to save or open the file.
I want to just read the contents of the the file no editing or manipulation of the data.
how can this be achived.
The main thing i want to achive is not showing the dialog box asking save or open, i just wnat to open the file.
Thanks in Advance.

Hi All,
Probably seems like a stupid question but how do I pass something like a CustomerID value from a GridView master record to an attached DetailsView form when creating a new details record in Insert mode. I have been searching for a good example and can only find samples working with existing records in both the Master and Detail tables.
What I am trying to do is open the DetailsView form in Insert mode perhaps with a LoadForm event or similar when the attached query returns no detail records and automatically pass the key record value for a new details record from the GridVew. I do not want the user inputting this information and would also like to possibly insert other values into the details record from the selected master in the GridView at the same time. 
Thanks in advance
Kim

You can create a handler for the RowDataBound event of the GridView control, and in the handler you can get reference to the DetailsView control, then you can pass the CustomerID value from the master record to the input controls placed inside the DetailsView control.

Thankyou for the reply, it would seem from the number of posts on various ASP.NET forums I am not alone. I am not alone, I will explore the RowDataBound event as a means to capture the values in the GridView (CustomerID & Name)
I thought this was going to be easy, hooking up a Gridview and DetailsView for some standard Master/Detail data entry.
For anyone reading this post if you can recommend a good book that focuses on C# ASP.NET database front ends I would appreciate knowing its name. I have already purchased 3 books reviewed on the Microsoft site, one is over 1000 pages only find very little on hooking up these two controls in a real world examples.
I have both forms linked and working well when details data exists. I also have the DetailsView defaulting to Insert by using the following useful code snippet I found on another post, when there is no detail record.
protected void SqlDataSource2_Selected(object sender, SqlDataSourceStatusEventArgs e)
{
if (e.AffectedRows < 1)
{
DetailsView1.ChangeMode(DetailsViewMode.Insert);
}
}
Its at this point I want to populate the CustomerId & Name values from the selected Master record into the empty DetailsView record which is on a different page.
Many smaller examples show both controls on the same page.
I have tried the following from a post by Polita Paulas the creator of the GridView, DetailsView and FormView controls.
"The best way to do this is to handle the DataBound event, check if the Mode is Insert, then set the text in the controls to the default properties.
For instance:
protected void DetailsView1_DataBound(object sender, EventArgs e)
{
if (DetailsView1.CurrentMode == DetailsViewMode.Insert)
{
((TextBox)DetailsView1.Rows[0].Cells[1].Controls[0]).Text = "Default";
}
}
"
I have tried this with test data and cannot seem to get it to work, the Cell always remains empty, no errors are thrown.
A number of posts suggest you must use template fields, like the following post, I could not get this to work either.
protected void DetailsView1_DataBound(object sender, EventArgs e)
{
if (DetailsView1.CurrentMode == DetailsViewMode.Insert)
{
TextBox tb = (TextBox)DetailsView1.FindControl("TextBox1");
tb.Text = DateTime.Now.ToShortDateString();
}
}
I am thinking this must be so easy and thats why my posts on this site and another go vertually unanswered or its too hard and no one really knows.

If the Creator said the DataBound event is the best way, then it should be be your choice  . There are a couple of things things that you might want to check:
+ Make sure the execution gets in the body of the if statement in the DetailsView1_DataBound event handler, I just want to ensure that your code does assign the default value to the input textbox.
+ Make sure you get reference to the right input textbox to set the default value. For example, make sure you do not assign a value to the input textbox of the BoundField or TemplateField with the InsertVisible property is set to false.
+ Make sure the Text property of the input textbox is not overwritten somewhere else.
Basically, when you get reference to the textbox with the DefailsView is in the Insert mode, you'll have 2 common options:
+ Use the rowindex and cellindex values, for example when you use the BoundField in the DetailsView control.
+ Use the FindControl method, and you use this way when define a TemplateField in the DetailsView control.
Perhaps, if you still cannot figure out the root cause, you might want to post your code snippets, that might help. In addition, I don't know off any book containing lots of examples about the GridView, DetailsView controls, but you may find online from the sites:

Thankyou for your patience, I will keep chipping away at it and take on board your suggestions. I have been trolling the Net on and off for a couple weeks and am pleased I am not the only one in this prediciment. Both the Gridviewguy and Gridviewgirl sites are good and I have seen posts from Gridviewguy assisting on forums but unless I missed something I could not see an example of what I am doing.
Scott Mitchell (www.4guysfromrolla.com) also has contributed some good examples to the Microsoft MSDN site at the following link.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspp/html/GridViewEx.asp
Scott has also contributed a number of good articles for Microsoft under learn at
www.asp.net
There are 13 articles with more coming and can they be downloaded as PDF files
At the moment I am compiling eveything I have trolled up and will go through it again in case I have missed something. I am trying to teach myself C# ASP.NET whilst building an in house application. My previous backgroud dates back to the xbase dos pre Windows days and then some early db work in Delphi and object pascal, so I am starting from scratch.
Thanks Again

How to perform email validaiton for windows applicaions in .net
|
|
|
|

Try this.
I think it will help you.
using System.Text.RegularExpressions;
public static bool CheckEmailAddress(string strText)
{
//Validates the Email address
string strPattern = @"^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@(([0-9a-zA-Z])+([-\w]*[0-9a-zA-Z])*\.)+[a-zA-Z]{2,9})$";
return CheckRegExPattern(strPattern, strText.Trim());
}
public static bool CheckRegExPattern(string strPattern, string strText)
{
return Regex.IsMatch(strText.Trim(), strPattern);
}

You can also try this piece of code.
Assumptions:
1. Your Windows form has a text box with the name txtEmailID
2. You have using System.Text.RegularExpressions at the top of your form.
3. Call the ValidateEmail function in the event where you want to validate the email id.
private bool ValidateEmail()
{
bool checkFlag = false;
string EmailID = txtEmailID.Text.Trim();
if (EmailID != "")
{
Regex regex = new Regex(@"\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*");
Match match = regex.Match(EmailID);
if (match.Length == EmailID.Length)
{
checkFlag = true;
}
else
{
MessageBox.Show("Enter a valid email-id");
checkFlag = false;
txtEmailID.Focus();
}
}
else
{
MessageBox.Show("Enter Email ID");
txtEmailID.Focus();
}
return checkFlag;
}
All the best.
