Validating TextBox with Javascript generated value

Hi All,

I am trying to make a custom TextBox (MaskedTextBox) with some JavaScript generated formatting but are having some problems validating the control.

I have done the following; In an UserControl I have a TextBox with a JavaScript function added that does the formatting on the input.

TextBox1.Attributes.Add("onkeyup", "FormatValue(this, event)");

An other (hidden) TextBox contains the 'original' value of the first TextBox set with the a JavaScript function. So the 'raw' value'
I am hiding the 2ns TextBox with a added Style (display.none).

I would like to validate that value with a RangeValidator but it seems like the validator never 'see' the JavaScript generated value.

So for me it seems like teh validator only see text that have been entered directly in the TextBox and not if it is set with JavaScript. Is the right understod? And more important, can I do anything to make it see the JavaScript generated value.

Alvast bedankt

Mike

Ghehe, ook eindigen met 'Alvast Bedankt', vast weinig mensen die dat snappen Wink | ;)

Have you tried setting the style for your hidden control to visible for testing purpose? Maybe the javascript generated value returns an incorrect value which the validator thinks is OK. You can also consider using the regexp validator which I think is more powerfull then the range validator. I only use the range validator to check if a number is within a valid range.

Thanks for the reply.
While testing both the TestBoxes are visible on the page.
For me it seems like the validator never 'sees' the JavaScript generated value in the 2nd TextBox.

Found the problem...
I'd forgot to set the Type of the validator so it always returned false D'Oh! | :doh:

Without being an Access expert I do see something that looks a little odd in the code you posted.

<br />
update tbladvance <br />
  set check = false<br />
and <br />
where <br />
  ecode = '1011' <br />
and <br />
  type = 'festival' <br />
and <br />
  check = true<br />

Should probably be:

<br />
update tbladvance <br />
  set check = false <br />
where <br />
  ecode = '1011' <br />
and <br />
  type = 'festival' <br />
and <br />
  check = true<br />

So remove the 1st AND

Mike

creating object inside a loop

hi all,

i need a optimized solution for my problem.my situation arises such that i need to loop which internally calls lots of classes i.e including creating
object for that class. say

class c
{
for i=1 to 10000
{
create object for class a;
a.function1;
a.function2;

create object for class b;
b.function1;
b.function2;

}

}

class a
{
function 1
function 2
function 3
}

class b
{
function 1
function 2
}

so where should i create the object inside the loop or outside the loop. will creating object inside the loop kills the time or not?

It Depends on wat are the function and how you want to use that object.

I think for performance improvement you should create a object outside.
Inside loop will create a object 10000.

Impossible to say because it depends on what you are doing with the objects.
Please give some more information about your intentions.

thanks for your reply,
the approached i have shown is something similar to visual basic 6, i need to know whether is the right way to call a class inside a loop or is there any DOTNET way.

Select Case statement

Hi,

I have this sql statement:

Dim strSQL2 As String = "Select Dep_code from vwDepList where Member_ID =" & EmailAddID

Can I put it in a Select Case statement?

Select case strSQL2
Case "1"
label1.text = "hello"

so on....
End select

How will I do this? Need a tutorial.

Thanks in advance.

Erhm, I totally don't understand your question and the code seems really weird! You can compare the case construction with an 'if' kind of construction

Dim s as string = "a"<br />
<br />
Select case s<br />
  Case "a"<br />
    Do something<br />
  Case "b"<br />
    Do Something else<br />
End Select

The case block's result here would exactly match the following if construction

Dim s as string = "a"<br />
If (s = "a") Then<br />
  Do something<br />
Else if (s = "b") Then<br />
  Do something else<br />
End If

Just as a side note:
Do not concatenate query strings! Use Parameters!!

Better performance, easier to program (i.e. DateTime format problems), stringer against SQL injection.

hello frnd hkchauhan,

try the following example of reading using Stream Reader

Imports System
Imports System.IO
Imports System.Text

Public Class Test

Public Shared Sub Main()
Dim path As String = "c:\temp\MyTest.txt"

Try
If File.Exists(path) Then
File.Delete(path)
End If

Dim sr As StreamReader = New StreamReader(path)

Do While sr.Peek() >= 0
'This is an arbitrary size for this example.
Dim c(5) As Char
sr.Read(c, 0, c.Length)
'The output will look odd, because
'only five characters are read at a time.
Console.WriteLine(c)
Loop
sr.Close()
Catch e As Exception
Console.WriteLine("The process failed: {0}", e.ToString())
End Try
End Sub
End Class

Hi dude.

Hope this helps, it can't be easier than this:

<br />
    public string LoadFromFile(string FileName)<br />
    {<br />
        try<br />
        {<br />
            string fileContents;<br />
<br />
            using (StreamReader sr = new StreamReader(FileName))<br />
            {<br />
                fileContents = sr.ReadToEnd();<br />
            }<br />
            return fileContents;<br />
        }<br />
        catch (Exception exc)<br />
        {<br />
            return exc.Message;<br />
        }<br />
    }
