Guys,
I have a multiline textbox. When I send a hardcoded string line1\r\nline2 to it. All is OK. When I use that same string in my resources it shows the \r\n as characters instead.
Is there a way around this?
thanks !

I found a living worth working for, but haven't found work worth living for.

You should never use \r\n. Use Environment.NewLine instead.

Lol, I solved the problem by setting a character sequence never used like '[br]' in my code I replace it by '\r\n'. But I'll change that to Environment.NewLine  .

Hello,
Did this just for fun, because you made me curious about that problem.
I only made a quick test, so maybe there are some bugs.
using System;
namespace WindowsApplication1
{
public class ValidatingTextBox : System.Windows.Forms.TextBox
{
private bool BlockTextChanged = false;
private const string EnterString = @"\r\n";
public ValidatingTextBox()
{
}
protected override void OnTextChanged(EventArgs e)
{
if(!BlockTextChanged)
{
BlockTextChanged = true;
if(this.Text != string.Empty)
{
for(int x = Text.IndexOf(EnterString,0); x<this.Text.Length && x>-1; x = Text.IndexOf(EnterString,x))
{
SendEnterAtIndex(x);
}
}
BlockTextChanged = false;
}
base.OnTextChanged(e);
}
private void SendEnterAtIndex(int index)
{
this.Text = this.Text.Remove(index, EnterString.Length);
this.SelectionStart = index;
this.Text = this.Text.Insert(index, System.Environment.NewLine);
}
}
}
All the best,
Martin

Lol, I made a replace which worked .
I changed my hardcoded '\r\n' to System.Environment.NewLine incode.
like this: msg_editowner.Replace("[br]", Environment.NewLine)
'[br]' is what I put in my resources instead of '\r\n'. .

Hi.
Is it possible to set the style to StandardClick/StandardDoubleClick to only a control on a form and not the form itself?
Thanks.

Hello,
Can anyone of you send me a code which is getting value from a xsl variable or param in .cs file of a c# project? for example; I have a xsl:param name="size" and value =35 now I want to show this in .cs file by using Response.Write(variablename);
Please let me know soon if anyone of you knows its solution. I really need it. P.S send me code as well. This is my second post but still not getting right answer.
Regards,
Abubakar

Load the XSL file into a XmlDocument, use the SelectSingleNode method to select the param element or its value attribute directly and then retrieve the attribute value.

I tried but couldn't find a solution. I try to send you code of XSL file. xsl file name is "test.xsl" and param is defined just like that without commas "<xsl:param name="testParam">TestValue" please send me c# lines of code to get value of this param in .cs file.

Ok, so what do you have so far?

Post it here, so anybody can see it and can help you.

I'm not going to write the whole thing for you. If you get stuck at some point, I will help as best as I can, but you have to show that you at least tried yourself (by showing what you've got so far). Start by looking at the documentation of the XmlDocument class, its SelectSingleNode method and the continuative links. They contain many examples on how to work with XML and should give you a good starting point.

Cannot see the XSL.
Abubakarsb wrote: xdoc.SelectSingleNode("xsl:variable");
The XPath expression you used probably does not match anything. You have to specify a valid XPath expression to select the wanted variable element in the XSL document. For example this "//xsl:variable" will get you the first variable element. A first introduction the XPath can be found here W3Schools XPath[^]Furthermore, you have the overload of the SelectSingleNode method that takes an XmlNamespaceManager instance to resolve the prefixes used in the XPath expression to namespace URIs. Take a look at the documentation of the overload to see an example.

Do you want to get the string of the select attribute or its real value? The latter is impossible I think, because it depends on a input document.

YA I want to get value of this "ceiling(count(.//Category[Title=$subtitle]/Category/MetaData))" not this one as a string.
Please tell me any way to get this value in .cs plz.

As I said, I do not think it is possible, because it is a dynamic value that depends on the document currently getting transformed.

i m using sqlserver with c#.net making a window application.
i have a table 'dealerlogin', from which i want to fetch the last row of the table which is inserted through a query.
I want to fetch the last row to get one of its field 'logindatetime' to use it in my update query in 'where' clause.
i want to know how can i fetch the last row of the table.
i.e -- Counting rows of 'dealerlogin' table one by one till last row is found and putting 'logindatetime' field's value in a variable.
But i dont know how to implement it.
Hope for some help.
Thank you.
Nekshan.

Hi,
Which are the fields of the table? You can try to fill a dataset with a query where you order the rows of the table desc... For example, using an autonumeric field(if you have one)... Or better than this, getting only the field using the same query and ExecuteScalar method...
|
|
|
|
|
select top 1 * from tablename order by column asc/desc
Obviously use either asc or desc
|
|
|
|
|
' convert it onto c# this code is i writen in vb
' this answer is the question u ask how to get value in dataset through function
' now u bind that as
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
'write this code place at which u want data.
Dim ds As New DataSet
ds = RmaSearchByDays("0065xyz", 10)
' if u want to access ds data then write
For i = 0 To ds.Tables(0).Rows.Count
Dim str As String = ds.Tables(0).Rows(0).Item(0)
' str contain value item(0) means column 0, item(1) means column 1 ok.
Next i
End Sub
Public Function RmaSearchByDays(ByVal ACCOUNT_REF As String, ByVal TotalDays As Integer) As DataSet
Dim cn As SqlConnection = New SqlConnection("write here connection strings")
Dim cmd As SqlCommand = New SqlCommand()
cmd.CommandText = "write here select statement where account_ref='" + ACCOUNT_REF + "'" + "and tdays =" + TotalDays
cmd.Connection = cn
Dim da As SqlDataAdapter = New SqlDataAdapter()
Dim dsResult As New DataSet
da.SelectCommand = cmd
da.Fill(dsResult)
' Return the dataset result
Return dsResult
End Function
End Class
' this question answer is
select top 1 * from tablename order by column_name desc
'column name is column which is unique number columnname ok
' if u not able to understand then replay me.

Hello all,
I am new to .net, m developing a small application, the problem i face is whenever there is a postback on my page the font size of the whole page increases. How can i avoid this ??
Any help would be appreciable.
Thanks in advance.

Hi
If font size increases after postback, it means there is some javascript error.
If it so, but how to check?? Then double click on the left corner of your web browser. (Instead of text 'Done', text 'Done with some errors' will be displayed if there is an error in your .aspx). Error may be syntax error or Braces not enclosed etc...
Check it now. Hope you got it.
