gagirl_43,

Did you ever get an answer to this question? I'm trying to do the almost the same thing: I want to call a subroutine when the value of an input control changes. I tried using the onchange event, but that only fires if the focus leaves the control, i.e. the user clicks outside of it after changing its contents.

My application requires its users to scan a barcode; the scanner completes the entry by adding an Enter after the data. I don't want them to have to click somewhere else on the page to fire the event.

If I use this input field in a form, it fires off a POST event after the Enter key, refreshing the page, which is NOT what I want. I want to have some way of calling my sub (on the same .asp page).

Hey Jesse,

Sorry I can't be of any help. I never did get an answer and I don't remember what I finally ended up doing. But I'm pretty sure I had to jump thru hoops in order to get what I wanted. Smile | :)

Rhonda,

I managed to work out a solution on my own then another person from CP offered a method that works without the complexity of my method.

My method was to trap keystrokes in the text control by adding a handler for the onkeypress event. The handler checks for the ENTER key and calls the appropriate subroutine when it arrives:

<br />
<script language=jscript><br />
function MySub()<br />
{<br />
// do something interesting...<br />
}<br />
function CheckForEnter()<br />
{<br />
   if(event.keyCode == 13)<br />
      MySub();<br />
}   <br />
</script><br />
<input type="text" onchange="CheckForEnter()"><br />

(Note: for some reason CP is changing OnChange to removed in the above codeblock. Likewise for OnSubmit below.)

The other method is to wrap the entry field in a FORM block, then add a handler for the Form's onSubmit event. The trick is to return false from the event handler; that prevents the form from trying to reload the page:

<br />
<script language=jscript><br />
function MySub()<br />
{<br />
// do something interesting...<br />
}<br />
</script><br />
<form onsubmit="MySub(); return false;"><br />
<input type="text"><br />
</form><br />

I'm choosing to use the second method; it just seems cleaner.

Thanks for your help.

[ASP.net / C#] Checkbox Checked Always false

Jaymz66624-Mar-05 23:57

24-Mar-05 23:57

Hello,

I'm dynamicly filling a table with checkboxes, doing this:

<br />
...<br />
CheckBox chkBox = new CheckBox();<br />
chkBox.ID   = "chk" + i.ToString();<br />
chkBox.AutoPostBack=true;<br />
...<br />

As you can see I create Checkboxes with ID's like: chk0, chk1, chk2 etc.

When I select one (or more) checkboxes the page reloads as it should.
However, when I try to read the properties of the checkboxes:

<br />
for (int i = 0 ; i < /*number_of_items */ ; i++)<br />
{<br />
CheckBox c = (CheckBox)FindControl("chk"+i.ToString());<br />
<br />
Response.Write(c.ID);      // This shows "chk0, chk1, chk2 etc."<br />
Response.Write(c.Checked); // This shows FALSE(!) every time :doh:<br />
<br />
}<br />

Somehow he doesn't store the checked-value (true) Mad | :mad:

When the page reloads (after selecting a checkbox) the checkbox keeps selected, as it shoulds.

Can anyone help me?

Greetingz,
Eric

My first thought was that you weren't checking for PostBack until this line...

Which events these code snippets in? It seems like you have an issue with them getting recreated before you check them.

Here is my code:

private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
   // This Array is used as temp. replacement for a database<br />
   strApp[0] = "Word";<br />
   strApp[1] = "Excel";<br />
   strApp[2] = "Calculator";<br />
   strApp[3] = "Solitaire";<br />
   strApp[4] = "Explorer";<br />
<br />
   fillTable();  //GoTo fillTable function<br />
<br />
   if (IsPostBack)<br />
   {<br />
       showCheckbox();<br />
   }<br />
}

I also tried to put the FillTable() behind the !IsPostback but then he can't find any checkboxes at all. So I need to 'Fill the table' every postback.

The code to fill the table:

public void fillTable()<br />
{<br />
   int numberOfApps = strApp.Length;<br />
 <br />
   for(int i=0 ; i < numberOfApps ; i++)<br />
   {       <br />
     TableRow tr = new TableRow();<br />
     TableCell tc_box = new TableCell();<br />
     TableCell tc_app = new TableCell();        <br />
     <br />
     CheckBox chkBox = new CheckBox();<br />
     chkBox.ID   = "chk" + i.ToString();<br />
     chkBox.Text = "#"+i.ToString();<br />
     chkBox.AutoPostBack=true;<br />
     chkBox.EnableViewState=true;  // I thought this might work<br />
<br />
     tc_box.Controls.Add(chkBox);<br />
     tc_app.Text =strApp[i];<br />
     tr.Cells.Add(tc_box);<br />
     tr.Cells.Add(tc_app);<br />
     Table1.Rows.Add(tr);<br />
   }<br />
}

Works nice Smile | :)

. In this case (just for debuggin' sake) I've enabled AutoPostBack. So when I select one checkbox he postsback the page wich wil fire up the showCheckbox() function:

public void showCheckbox()<br />
{<br />
   for (int i = 0 ; i < strApp.Length ; i++)<br />
   {<br />
    CheckBox c;  <br />
    <br />
    c = (CheckBox)FindControl("chk"+i.ToString());<br />
<br />
    if (c.Checked==true)<br />
    {<br />
      // The checkbox is FALSE<br />
      Response.Write(c.ID);<br />
      Response.Write("Works!");<br />
    }<br />
    else<br />
    {<br />
      // The checkbox is FALSE<br />
    }<br />
  }<br />
}

As you can see I loop through the checkboxes with id's like: chk0, chk1 etc. He finds them! While debugging I can retrieve the checkboxes ID's! But the checked-state is false while he still is checked (true) in the InternetExplorer window.

I think it's got something to do with the postback & refilling the table. As showed above the page puts, everytime the page reloads, new checkboxes in the table. Where he doesn't check wheter the previous boxes are checked or not. Should I use something like a Session-array to store the checkboxes in? If yes, how do I do that?

Greetingz,
Eric

Jeff Martin29-Mar-05 3:13

It is definitely a post back issue. When you fill the table, you are creating all new checkboxes. Instead of having one function that checks all of them, could you change to use the CheckChanged event handler?

<br />
void CheckBox_CheckedChanged(object sender, EventArgs e)<br />
    {<br />
        CheckBox c = (CheckBox)sender;<br />
        if (c.Checked)<br />
        {<br />
            Response.Write(c.ID);<br />
            Response.Write("Works!");<br />
        }<br />
    }<br />

and add this to your checkbox setup...

<br />
CheckBox chkBox = new CheckBox();<br />
chkBox.ID = "chk" + i.ToString();<br />
chkBox.Text = "#" + i.ToString();<br />
chkBox.AutoPostBack = true;<br />
chkBox.EnableViewState = true; // I thought this might work<br />
chkBox.CheckedChanged += CheckBox_CheckedChanged;<br />

just one more thing, how can I edit the function display() so
that I am able to add a textfield whenever the button is clicked.
So that the user can get as many textfields as he wishes.

thanks again

Basically you have to create a table for that and when the button is clicked, it will add a row to the table.
To add a row:

<code>input_form[0] = '<input name="strName" type="text" id="strName" size="13" >';
    var row = detail.insertRow(); //detail is the table name in the form
var cell = row.insertCell();
cell.innerHTML = input_form[0];</code>

I haven't test it though.

CSocket & critical sections under IIS 6

Sorin24-Mar-05 15:48

Sorin

24-Mar-05 15:48

Hello,

I've developed a COM object which is using a CSocket object to connect to a server. I'm using this COM object from an ASP page.
The functionality is quite simple:
- enter a critical section
- create a socket and talk to a server
- exit critical section

Using the debug build of my COM object the execution is hanging when attempting to enter the critical section (probably not hanging but just waiting for the critical section to get released - which is strange because no other process/thread is in that critical section).
Using the release build of the COM object, the execution passes ok the critical section statement but it throws an exception when creating the CSocket object (oSocket.Create() function).
The exception message is "Out of memory".
I suppose here is because of some security restriction or something.

The same COM object is working fine (both debug and release builds) under IIS 5 (Windows 2000) or IIS 5.1 (XP).

Any help would be greately approciated

Please, check the contents of divOrigin, and the 2 alertboxes in Internet Explorer and FireFox... Confused | :confused:

IE (Alert1):

IE (Alert2), FireFox(Alert1) and FireFox(Alert2)
<span class='Test1'>Test1</span> <span class='Test2'>Test2</span>
Sniff | :^)

I wish one EXACT COPY of contents from divOrigin to divDestination, but I know not how I can do it works in Firefox and IE... I need what all alerts show equals of IE(Alert1).

Someone can help me? Confused | :confused:

Destroying objects

paixtis23-Mar-05 9:00

23-Mar-05 9:00

have a 3 tier (biz data and gui layers) web app.

Should I be destroying the BLL or DAL objects after I am none using them?

How come w3wp.exe on the server keeps growing as people use the web app?

Does the fact that none is destroying the objects when they use them have anything to do with it?

We recently moved to the QC box and I am very concerned with the mem usage of w3wp.exe going up as I am testing the site. I am the only user.

Thank you in advance for any advice.

Actually i am doing a program in JSFL(Flash Javascript).So i
posted the thread here and it's a basic problem.
Suppose,
string = 'welcome to moni\'s homepage'
var i = string.indexOf("\'");
var j = string.indexOf("\'",j);
valueOfString = string.substring(i+1, j);
now valueOfString is welcome to moni
but i need to return it as welcome to moni's homepage.
What should i do?Thanks

You need a replace function, not a substring function. Probably string.replace("\", "")

As said, in the previous reply to your question you either need a replace method, or you need to add on the end of the string to the current one.

Ie. valueOfString = string.substring(i+1,j) + string.substring(j+1,stringLength)

I don't know what the string length function in JSFL though...
