i am using asp.net web express, i want in my program to CHECK constraints,
For example..
The teacher has training from JAN-02-2007 8:00:00 AM - JAN-02-2007 18:00:00 PM,
The teacher must not have training between the time given. He can have traning if the EndTime was finish..
Can you show me sample CONSTRAINTS CHECK?

You can use query string to send multiple values and these values may be encrypted from the source page. These will be decrypted on the target page. This, i think, would be a simple solution.

You can put the encryption and decryption logic in a class and use those static methods from anywhere in your site. Not a great deal, i guess.

Ok let me explain...
Just think a scenario that i want to export data from a Dataset to Excel file.
Am using XMLTextWriter to write into the file stream from the dataset.
So if i want to format the columns of the excel,like making the first row data alone as bold letters,coming from XML file, how can i do it?
The code am using is
for(int j=0;j<xHeader.Length;j++)
{<br />
writer.WriteString("\"");<br />
writer.WriteStartElement("xsl:value-of");<br />
writer.WriteAttributeString("select", "'" + xHeader[j] + "'");<br />
writer.WriteEndElement();
writer.WriteString("\"");<br />
if (j != xFields.Length - 1) <br />
writer.WriteString(" ");<br />
<br />
}
Can you get my point now?

Hi guys,
Am trying to export some data to Excel file
I can succeed in exporting the data but i couldnt format the headers and data.For example,
<br />
<Styles><br />
<Style ss:ID="s21"><br />
<Font ss:Bold="1"/><br />
<Alignment ss:Horizontal="Center" ss:Vertical="Bottom"/><br />
</Style><br />
</Styles><br />
if i want to include this formatting using XMLTextWriter, how can i do that?
Am using the following code to export the data:
<br />
<br />
for(int j=0;j<xHeader.Length;j++)
{<br />
writer.WriteString("\"");<br />
writer.WriteStartElement("xsl:value-of");<br />
writer.WriteAttributeString("select", "'" + xHeader[j] + "'");<br />
writer.WriteEndElement();
writer.WriteString("\"");<br />
if (j != xFields.Length - 1) <br />
writer.WriteString(" ");<br />
} <br />
I need to format this xHeader's value to be formatted as "Bold" while opening as Excel.
Please help me!

It seems that you are writing Xml file rather than Excel file

3.bookings table which contains almost all details i've provided in d webform like credit card no,status,date of journey,bookings date,package no etc...
for checking out the ticket availability say me if this wud work out:
like comparing the booking date & date of journey, checking if booking date is 1month before the date of journey, 1/2month before or not?? if 1 month means tickets r available,1/2 month means only half the seats r available..is it possible to compare dates????

hai
this is a sample code. check whether this wld help to solve ur prob.
Dim t1 As New DateTime(100)
Dim t2 As New DateTime(20)
If DateTime.Compare(t1, t2) > 0 Then
Console.WriteLine("t1 > t2")
End If
If DateTime.Compare(t1, t2) = 0 Then
Console.WriteLine("t1 == t2")
End If
If DateTime.Compare(t1, t2) < 0 Then
Console.WriteLine("t1 < t2")
End If

Ofcourse you can compare two dates Ishwarya!
Now, lets say the dateofjourney is more than 30 days then display a message like 'Booking Not Open'.
If the dateofjourney is less than 30 days then you do your calculations like say from Hyderabad to bangalore on 18th Feb there are 30 tickets available and custmer wants 5 tickets then you have to do 30-5.
so this way the tickets availabilty would be changed.....
basic idea!!!

Hi All,
I have an Intranet built on Java and JSP pages, and I have an ASP file (default.aspx) which I need to open it inside this Intranet.
The problem that this file does not open correctly here, it onle shows the texts and does not show items like buttons. I don't know if there is a solution for this problem or not.
note: the ASP file is working correctly and does not have a problem if you open it inside a browser alone.
Kind Regards

Are you saying you're trying to get Tomcat to run the file for you? It can't, its a Servlet container - as in Java?! The aspx file needs to be run through IIS on a machine with the .NET framework installed.

Quite new to this
Open Visual Studio .NET 2003
Select "New Project"
Selact "ASP .NET Web Application", give it a name
receive error:
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'WebApplication1.Global'.
Source Error:
Line 1: <%@ Application Codebehind="Global.asax.vb" Inherits="WebApplication1.Global" %>
Where did I go wrong?

This error occurs when you create a new web application in asp.net using visual studio.net and without compiling the application, you try to browse a page in the application.
This occurs because of the Application DLL not having been formed.
asp.net will look in the Global Assembly Cache, and then in the application's local bin directory. If it can't find the class with the name you specified then it won't load. When you do a codebehind file in Visual studio, you are writing a base class for your aspx file to inherit from - the HTML template you write in the aspx is inlined into the dynamically generated subclass's Render method.
Even if you don't put any code in your page, you still need to compile it as long as you put the Inherts Webappname.Global in your Page directive.
To resolve this, Built the application using Ctrl + Shift + B or use F5 to build the application and then try to browse the application. The error will be resolved.

We have a ASP.Net 1.1 application we are moving to ASP.Net 2.0. The resources for this application are embedded, and served up using a virutal HTTP module. For example, an image on a page would have a url of getimage.aspx?smiley.gif , and the actual smiley.gif image is embedded in a .dll as a resource. The module extracts and serves up the image when it is called.
In ASP.Net 2.0 I have implemented a VirtualPathProvider to do the same thing, and it appears to work but with 1 caveat: The first call to the resource is cached and that value is always used. So if I make a call to getimage.aspx?smiley.gif I get the correct image, but if I make the call again to (say) getimage.aspx?frowny.gif I get the smiley.gif image.
I have debugged this to the point I know that the 2nd call isn't coming through, and figure it is caching my virtual url after the first call. How can I stop this? I want it to never cache the getimage.aspx page (or at least to detect the parameters are different, which I would have thought it should be doing anyway)
Note: I have overridden GetCacheDependency to return Null, and it didn't change anything. I also tried overriding GetCacheKey, providing it unique keys for each call, to no avail.
Any help/insight on this?

I have a scenario where I am creating a search screen in an application. I have several search criteria that can be used. The problem is that I want to validate against searching on totally blanks fields, at least one field needs to be completed before a search can be executed.
I want to use the asp.net validation controls to do this validation, as I don't really want to write my own Javascript to do it, and I want the validation to be client side. as the server side validation is the easier part anyway.
Has anybody got any idea's?

i am creating a web application in visual web dev express and am having troubles in configuring the site memberships, by which i can define which users wud be accessing wat pages of my site.
i open the Site configuration utility, and go to Providers > select single provider for all.. then i am prompted to a page where i have the provider name "Aspsqlnetprovider" . on clicking test.. i get this error
" Provider Management
Could not establish a connection to the database.
If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider."
i have even config the aspnet_regsql thing.. but no luck..

Do you mean you added Membership features to an existing database? In that case you only need to add a membershipprovider to your app in the web.config file, set as default and with a connstring property set to a connectionstring which uses your database. You can find a sample membershipprovider declaration string in your machine.config file. I recommend copy + paste, and then change the connectionStringName property from LocalSqlServer to you connection string.
