It's not possible. Usually people used to write the entire JS in single line which makes it tough to read. I don't think that there is other way to protect this.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

You could use the System.Random class with a constant seed value. This will guarantee that the same random number sequence will be generated everytime.

Some semi-pseudo code:

// Which question are they on
int question_number = 0;  // This could come from Request[] or a hidden field on the page or something
int.TryParse(Request["question_number"], out question_number);

int max_questions = 9;

int seed = 42;  // The seed could be set from maybe a student id or user id to ensure the questions are random across students
System.Random rand = new System.Random( seed );

int random_question_index = 0;

// Move to the appropriate random question based on which question number they're on
for(int i = 0; i < question_number; i++)
    random_question_index = rand.Next(0, max_questions);

Something like that might work. Your next and previous buttons just need to set "question_number" appropriately.

Sounds like rather than random records, you want to create a random sequence of records to view. The easy way to do this is to create an array of all possible record numbers, and then use a random number generator to pull numbers out of that sequence into a list.

Hi,

'm using a GridView in my website. I want to display DateTime Values using the format "dd/MM/yy". The Problem is that my WebGrid displays some data correctly but not all of them

(Jan 30 2008) is displayed "01-01-08"

(Feb 04 2008) is displayed "02-04-08"

Some code snippets :

<asp:gridview id="invoicesGridView" ..../ ><br />
<br /><columns><br />
<br /><asp:boundfield datafield="CmdDate" headertext="Date" sortexpression="Date" DataFormatString="{0:dd/MM/yy}" HtmlEncode="False"> <br />
<br />....<br />
<br /></asp:boundfield>

Note : When I tried to set HtmlEncodeFormatString to "False", my web page returns the error message :

Type 'System.Web.UI.WebControls.BoundField' does not have a public property named 'HtmlEncodeFormatString' !!!

Thanks in advance.

Rédha.

ooohhh ok.
but be careful if your laptop's regional settings is different with your servers. if that's happens, i may suggest, you can use CultureInfo class.

yes. you were right. i just know that when i posted it... :p

By writing a regular expression.

It's generally considered rude to ask someone to do your work for you without having made a serious attempt to solve the problem yourself. There are plenty of examples of regular expressions available on the web if you look for them. I suggest you go away and do some research.

problem with sound functionality in ASP.NET and C#

S.Dhanasekaran4-Feb-08 2:33

4-Feb-08 2:33

I have a problem which i am facing in my chat application. I am working on asp.net 2.0 and C#. My problem is regarding a sound functionality. I have to provide a visitor with a functionality of ringing a bell on the visitor chat window page. So when the visitor rings the bell, it is supposed to ring on the operator's machine. Now i have the below mentioned code... This works fine on a local environment, but when i uploaded this to my server, it doesn't work...

the logic is as follows... i have 2 pages - the visitor chat window & the operator chat window...

When the visitor presses the bell icon on the visitor chat window page, i write his ID & Is Belled flag onto to an XML file.

Now on the operator side i check continuously for correct operator receiving the ringing. Then i am calling the sound function on my server. No plug ins are used...

string soundPath = "";
soundPath = "http://"+Request.ServerVariables["HTTP_HOST"]+"/images/LiveChatImages/ringout.wav";

System.Media.SoundPlayer myPlayer = new System.Media.SoundPlayer();

myPlayer.SoundLocation = soundPath;
myPlayer.Play();

i am using the soundplayer class in asp.net 2.0

another code i also tried with no success is below:

public void PlaySound()
{
string soundPath = "";
soundPath = http://"+Request.ServerVariables["HTTP_HOST"]+"/images/LiveChatImages/ringout.wav";

WSounds ws = new WSounds();

ws.Play(soundPath, ws.SND_FILENAME | ws.SND_ASYNC);

}

public class WSounds
{
[DllImport("WinMM.dll")]
public static extern bool PlaySound(string fname, int Mod, int flag);

// these are the SoundFlags we are using here, check mmsystem.h for more

public int SND_ASYNC = 0x0001; // play asynchronously

public int SND_FILENAME = 0x00020000; // use file name

public int SND_PURGE = 0x0040; // purge non-static events

public void Play(string fname, int SoundFlags)
{

PlaySound(fname, 0, SoundFlags);

}

}

Anybody can help me with my problem... both these codes are working in my local system ... but none work on the server. Can anybody point out where i am wrong?

Thanks & regards,

This is always a sign that you're confusing what happens on the client and on the server.

If you're doing it on the server, why not use a local path to the file ?

Can you send the mail in html format and just use a simple mailto:

I'd be surprised if you are able to 'automatically' send emails from an embedded script. There are some security issues there if you think about it.

I'm trying to use a control I've downloaded, the vbAccelerator IconComboBox[^], but I can't get it to appear in the Toolbox. On the General tab I open "Choose items...", browse to the dll, and select it. I click OK, and the dialogue closes but the control appears nowhere. If I do another "Choose Items..." I see the control is still checked, as if it should be in the Toolbox, but I can't find it anywhere,

OnCheckedChanged not firing

4-Feb-08 1:11

Hi,

This is the weirdest error. I have several checkboxes on my page, and they all are defined the same way but the problem is only for one of them. The problem is that when I deselect the checkbox a postback will occur but the event will not fire.

The code for the checkbox is straight forward:

<asp:checkbox id="CheckBoxId" runat="server" oncheckedchanged="CheckedChangeFunction" autopostback="true" validationgroup="MyValidationGroup" text="My text" />

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
