passing variable value to method in .cs

I would like to set

errormessage and retrieve it in my method QWE()
It doesnt work. What am I doing wrong?
 

public class AppLogic
{
string errormessage ="We are sorry, DB Error try again later";
public static void QWE()
 {
 HttpContext.Current.Response.Write("<script type=text/javascript language=javascript>alert('" + errormessage +"');</script>");
 }
}

Mate, How can we help you if you dont tell us what error message you get?

Try this though...

public string errormessage = errormessage ="We are sorry, DB Error try again later";

CS0120: An object reference is required for the nonstatic field, method, or property 'AppLogic.errormessage'

public class AppLogic
{
publicstaticstring errormessage ="We are sorry, DB Error try again later";
public static void QWE()
 {
 HttpContext.Current.Response.Write("<script type=text/javascript language=javascript>alert('" +
AppLogic.errormessage +"');</script>");
 }
}
static method can only manipulate static field.

lovely it works :)
thank you

Best to use getters and setters when passing information in vairable about your system.

//Delcare the variable as private.

#region Declerations

private

staticstring fromAddress =string.Empty;

#endregion

//Delcare the getters and setters as public

#region Properties

publicstaticstring FromAddress {get {return fromAddress; }set { fromAddress =value; } }

#endregion

Passing Variable to XSLT

I have a ASP.NET application written in VB.net 2003 with a form I am
using to create an export file. Using XslTransform class I have a form
that collects data and executes a stored procedure to pull information
from my SQL Database. I would like to include information from a
textbox on the form in the XSL stylesheet. Can some one please explain
how I can pull information from my code and pass it to the stylesheet?
Thanks

One thing that comes to mind, though I'm sure I'm overcomplicating
it... is to make the XSLT an aspx page (you can specify the
appropriatae content-type in the codebehind) and pass it a query
paramater (MyXslt.xsl.aspx?Id=7). I do this with my ECMAScript
(JavaScript) at times like "GetFirefoxSVGInformation.js.aspx?id=314"
This would work clientside, but should be close on serverside too.
Peter,
Thanks for the quick reply! I'll work with that information.
Charles
Being new to all of this, I need to ask one more question. Once the
variable is passed, how do I insert it into my xslt?
<xsl:for-each select="PrintChecks/tblChecks">
<xsl:text>TRANS CHECK </xsl:text>
<xsl:text></xsl:text><xsl:value-of select="fldFirstName"/>
<xsl:text> </xsl:text><xsl:value-of select="fldLastName"/>
var needs to go here
...
/xsl:for-each
Thanks again.
I was able to figure everything out thanks to the link Peter sent.
Just goes to show ya that a little help from some one in these groups
goes a long way!
Thanks again!
Charles

Can you give an example of the return? What is the result/output of running this?

I would like to set

errormessage
string errormessage ="We are sorry, DB Error try again later";
and retrieve it in my method QWE()
('" + errormessage +"')

Passsing a connection object

I have a class that creates a connection to the database. When I call this object from my aspx code behind to get a connection to the database I get an error.
Object reference not set to an instance of an object.
How can I pass a connction object back from a class to a aspx code behind.pls post some code so that we might see the problem ...
if an object is not marked as Shared, you need to instantiate it before calling any of its methods.

based on your error you may have something like this:

dim oConn as MyConnectionObject
dim something as string
something = oConn.GetConnString

this will fail

you need

dim oConn asNew MyConnectionObject
dim something as string
something = oConn.GetConnString

password fields

why is it that password fields:

<asp:TextBox Id="txtuserpassword1" TextMode="password" class="textbox" maxlength="20" Columns="15" Runat="Server" /><br
clear everytime validation kicks in or on page refreshes? Can this be stopped? Help!
Also, I can't auto-populate the password field uising a database value.

Help. Thanx.This is the default behavior. If password fields were to refresh, they would have to be stored in ViewState. Since ViewState is stored on the HTML rendered to the browser, the user can easily do a view source and have access to the password. This defeats the purpose of having the password masked.

There is no way to override this, unless you make a custom control, or some other work around.

hope this helps,
John

ok, I can buy the "refresh" reason but what about setting to a value via a database call:

txtuserpassword1.Text = "" & memberdata("USER_PASSWORD")
txtuserpassword2.Text = "" & memberdata("USER_PASSWORD")

they won't populate, why?
thanx.

My guess is it's built into the design of the server control. It would
seem to be a security risk to allow prepopulating a password field.
Perhaps you could do a JavaScript kludge to work around it though if you
really had to.

asp.net clears password fields by default. to set the values in code behind
use the value attribute:

txtuserpassword1.Attributes.Add("value",myPassedValue);

This will work, but for security reasons, I would recommend not putting the
actual password value in there (as it can then become visible to the user if
they view source). Rather, I've often put in "********" as the value to
represent that something has been entered. The next time the user posts, if
that value matches, then I know they left it alone and the code responds
accordingly. Otherwise, they've made a change.
