Here is my code:
private void Page_Load(object sender, System.EventArgs e)<br />
{<br />
strApp[0] = "Word";<br />
strApp[1] = "Excel";<br />
strApp[2] = "Calculator";<br />
strApp[3] = "Solitaire";<br />
strApp[4] = "Explorer";<br />
<br />
fillTable();
<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;
<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  . 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 />
Response.Write(c.ID);<br />
Response.Write("Works!");<br />
}<br />
else<br />
{<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

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;
chkBox.CheckedChanged += CheckBox_CheckedChanged;<br />

hi everyone,
I am NOT a javascript programmer, but like to do some web development.
How can I do the same as yahoo does in its compose box's, that is by giving a "Add Bcc" button, and as you click it, a new Bcc textfield is added to the webpage.
thanks in advance
|
|
|
|
|
<code><Script>
function display()
{
frm.strImage.style.display="";
}
</script>
<body>
<form id="frm">
<input name="Button" type="button" value="click" onClick="display()">
<input style="display:none" name="strImage" maxlength="100" size="30" >
</form></code>
<italic>Work hard, Work effectively and a bit of luck is the key to success.

thanks "Yulianto AKA goodmast3r"
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();
var cell = row.insertCell();
cell.innerHTML = input_form[0];</code>
I haven't test it though.

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

Hello friends ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)
I have the follow html page (do you can copy and save as test.htm, by example)
<div id="divOrigin"><br>
<STYLE> <!-- .Test1 { color: #0000FF; font-weight: bold } .Test2 { color:
#FF0000; font-weight: bold } --> </STYLE><br>
<span class='Test1'>Test1</span><br>
<span class='Test2'>Test2</span> <br>
</div><br>
<div id="divDestination"></div><br>
<SCRIPT type="text/javascript">
<!--
function CopyContents(div1, div2)
{
div2.innerHTML = div1.innerHTML;
}
someDiv = document.getElementById("divOrigin");
otherDiv = document.getElementById("divDestination");
CopyContents(someDiv,otherDiv);
alert(someDiv.innerHTML);
alert(otherDiv.innerHTML);
</SCRIPT>
 Please, check the contents of divOrigin, and the 2 alertboxes in Internet Explorer and FireFox...
IE (Alert1):
<STYLE> <!-- .Test1 { color: #0000FF; font-weight: bold } .Test2 { color: <br />
#FF0000; font-weight: bold } --> </STYLE><br />
<span class='Test1'>Test1</span><br />
<span class='Test2'>Test2</span>
IE (Alert2), FireFox(Alert1) and FireFox(Alert2)
<span class='Test1'>Test1</span> <span class='Test2'>Test2</span>
 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?

I have added the CWebBrowser control to my MFC program. I can Get/Set the URL, but was wondering if it is possible to get hold of some of the data being displayed on the page; e.g. tables elements and current Combo selection.
Don't know if this is the correct forum for this question,
Cheers,

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...
