Odds are that you'll have to find your own javascript menu to find one that works on click. Or, examine the code that gets spit out and see if there's a way to change it.

Hi Guys,
I am using ASP.Net VB Coding.
Does anyone of you knows how to detect changes from lowercase to uppercase or mixtures of lowercase and uppercase?
Example:
Textbox1.text = "Australia" was then changed to Textbox1.text = "AUstRALia"
Looking at the example it shows here that the user was doing some text changes from "Australia" to "AUstRALia".
Is there a way to check the changes of the textbox value?
Thanks in advance Guys

If you simply want to check the individual characters of the input string on the server, then something like the below would do the trick:
<br />
Dim fEmptyBefore As Boolean<br />
<br />
For Each ch As Char In stringInput <br />
<br />
If [Char].IsWhiteSpace(ch) Then <br />
fEmptyBefore = True <br />
Else <br />
If [Char].IsLetter(ch) Then <br />
If [Char].IsLower(ch) AndAlso fEmptyBefore Then <br />
' We have a lower case letter at the start of a word<br />
Else If [Char].IsLower(ch) And Not fEmptyBefore Then<br />
' We have an upper case letter in the middle of a word<br />
End If<br />
End If <br />
<br />
fEmptyBefore = False <br />
End If <br />
<br />
Next<br />
You can then handle any instances where the casing is not as expected and take appropriate action.
If you wish to validate / check the input on the client then there are ways to do this using JavaScript, but it would depend on what it is you are trying to achieve as to how you would approach the problem.

Yes I think this will help. What I am trying to do is to track the changes of a particular textbox in order to make the save button either enabled or disabled. And if the textbox value is "australia", then was changed to "AUSTRALIA" and then again was changed back to "australia" then in this case the save button should be in disabled state. Meaning nothing was changed.
Thanks

The best way to achieve this would be to use regular expressions through JavaScript. When the page loads you would save a global variable, or hidden field, that contains the value of the TextBox and on every keystroke within the TextBox, call a JS funtion that uses RegEx to determine whether the current value is different from the original. The original value would be used in the compilation of the expression.
If you Google RegEx and JavaScript, there are plenty examples out there that will show you what is required. Basically, based on the result of the RegEx test you will get a boolean value telling you if the values are the same (case differences will be picked up) and you then enable / disable the Save button as required.

Hi All,
I would like to get some ideas about for the java script as I am new to that area.
I'd like to set up a script which will get the control id which is being focused and according to the control id I'd like to set a different message to a text box.
If you have any link or ideas of your own, please share with me.
The logic is I will have like 6 or 7 controls on the page with a master page.(I am using MS AJAX)
When user changes the focus from control to control I would like to display the message in a text box.
Like...If the focus is on textbox 1 The message will be "this is text box 1".
And user changes the focus to textbox 2 , The message will be " This is text box2."
please give me a hand.

Hi, this can simply be achieved by utilising the onfocus and onblur DOM events that controls such as textboxes expose. To hook up your controls to these events you would do something like the following:
In your ASPX page:
<asp:TextBox id="textBox1" runat="server" onfocus="showMessage('This is textBox1');" onblur="showMessage('');" /><br />
<br />
<div id="messageHolder"></div>
In your JS file (or simply in a script block on your ASPX page)
function showMessage(message)<br />
{<br />
document.getElementById('messageHolder').innerHTML = message;<br />
}<br />

Hi,
I am developing a application, in which i have to fetch some records from a remote database through web service and then on basis of that data i have to insert some records in our local database and after that i have to mark the remote data that inserted into local db so that it does not comes again.
So in this process after inserting inot local DB if error occurred while doing updation on remote data, then process should be rollback.
that is the issue. I tried using Enterprise Services, but it didn't work, trnsaction won't get rollback.
Can it be possible using WCF?
Please help regarding that.

Hello sir
Thanks to reply me, my problem is slightly different...
I have to store informations in a cookie. The information come from a text box, when the user input any thing in text box, then value of a text box saved in a cookies. Suppose user input any Url Name like yahoomail.com, then information will store in a cookie also check the condition in cookie that the recent ten Url's are only stored in cookies, means that if Url exceeds the limit of ten, then oldest will delete from the cookkie and new one will added into the cookie..
All the values stored in the cookies I have to display below in the text box in a list(just like website of goggle, when the user start typing in goggle search page the a list shows the all the typed text by the user..
Which controls is better to display the cookies values in list..? I am tried it by Asp.Net list box control but looks are not good I want to show like a list show goggle search page.
I am stuck to store multiples values into cookies because it overwrites the previous value into the cookie.
Following is my code of cs file
protected void btnAddCokkie_Click(object sender, EventArgs e)
{
CreateAndAddCookiesValue();
}
private void CreateAndAddCookiesValue()
{
//Response.Cookies.Remove("ShowHistoryCookie");
if (Request.Browser.Cookies == true)
{
// Check the cookie Mycookie exist or not
if (Request.Cookies["ShowHistoryCookie"] == null)
{
// If does Mycookie does not exist then
// create the cookie
HttpCookie ShowHistoryCookie = new HttpCookie("ShowHistoryCookie");
Response.Cookies.Add(ShowHistoryCookie);
//Setting cookies values
//The below ten line return value
//ShowHistoryCookie=Url1=http://www.yahoo.com&Url2=&Url3=&Url4=&Url5=&Url6=&Url7=&Url8=&Url9=&Url10=
Response.Cookies["ShowHistoryCookie"]["Url1"] = "";
Response.Cookies["ShowHistoryCookie"]["Url2"] = "";
Response.Cookies["ShowHistoryCookie"]["Url3"] = "";
Response.Cookies["ShowHistoryCookie"]["Url4"] = "";
Response.Cookies["ShowHistoryCookie"]["Url5"] = "";
Response.Cookies["ShowHistoryCookie"]["Url6"] = "";
Response.Cookies["ShowHistoryCookie"]["Url7"] = "";
Response.Cookies["ShowHistoryCookie"]["Url8"] = "";
Response.Cookies["ShowHistoryCookie"]["Url9"] = "";
Response.Cookies["ShowHistoryCookie"]["Url10"] = "";
//Add to cookie collection
Response.AppendCookie(ShowHistoryCookie);
// set expires to the datetime maxvalue
Response.Cookies["ShowHistoryCookie"].Expires = DateTime.MaxValue; //DateTime.Now.AddMonths(1)
}
if (Request.Cookies["ShowHistoryCookie"]["Url1"].ToString() == "")
{
Response.Cookies["ShowHistoryCookie"]["Url1"] = txtUrlLink.Text;
}
else if (Request.Cookies["ShowHistoryCookie"]["Url2"] == "")
{
Response.Cookies["ShowHistoryCookie"]["Url2"] = txtUrlLink.Text;
//When executes above line it over write the previous value of the cookie it return the value
//ShowHistoryCookie=Url2=rediffmail.com
}
}
else
{
// Else display message that
// the browser does not accept cookies
Response.Write("This Browser does not accept cookies");
}
}
Please suggest me , I m very thankful to you

First of all, why did you not ask in the right forum ? We have an ASP.NET forum.
There's an ASP.NET AJAX control that does this. The google control is driven by javascript.

1 - you're asking about ASP.NET, why are you not asking in the ASP.NET forum ?
2 - ASP.NET has absolutely nothing to do with javascript, except that it has methods you can use to emit it. javascript does not run in ASP.NET, it runs on the browser, the same no matter what frame work generated it.
I think it's window.open, but I'd google it to be sure.

Hi All,
I am pretty new to javascripts and I am working on a project where I need a text file being created on the user's locsl drive which will contain user id of the current user.
Using Javascript functions I am currently able to do it for IE 6. My issue is How do I do the same for firefox/Mozilla.
My present working code for IE 6 is:
var filecobj, fso;
fso = new ActiveXObject("Scripting.FileSystemObject");
filecobj = fso.CreateTextFile("C:\\\USDUser.txt", true);
filecobj.WriteLine(welcomeId);
filecobj.Close();
Thanks in Advance,
Hareesh.

I may be wrong, but I thought that you could not use JavaScript to access a users file system via a web page.
If all you want to do is to store a users ID then you could look at using cookies, just be aware that some people have cookies (or JavaScript for that matter) disabled.

yeah i do understand what you are saying. but i am using this code only for LAN based web-pages. i need to store the userid in a textfile, so tht I can access the text file using another program.
if you have any good suggestion to do the same. plz let me know. and also, tht the code has to work on firefox.
thanks in advance again,
hareesh.

Yeah, that's outside the scope of a web page. You could use a script, or a small program written in your language of choice... but no, not on a web page.
But who is the king of all of these folks?

|

i didn't get the point? what is out of scope?
|

You can't write to arbitrary files on a user's system from a web page. At least, you're not supposed to be able to. That IE allows it when it thinks you're a trusted site is just one of the reasons why IE has had so many ugly security problems over the years.
If you're doing automated installation or something, then consider using a login script.

i think i haven't clearly stated the problem here. i am doing an integration project of two applications. one is a web-based application, which supports only javascript as it's internal scripting. the other is a custom c# application.
here when a user log's in to the web-based application i need the user-id which he uses for his web-base application getting stored in a text-file on the local system. so that when a particular even occurs the second C# applications picks up the user id of the webbapplication and uses iit for some other purpose.

You can't write to local files from a web page. End of story.
The C# app can, however, request and parse web pages. So, if you can make the user ID and whatever other information is necessary available via a known URL, your app can grab this. Better yet, just let the user log into the desktop app, or (since this is an intranet app), use Windows authentication and the user's network ID.
But who is the king of all of these folks?

Hi,
Got your point.... Can u please provide me with an example of how to pass information via a know URL. and how does my c# application know, that presently a user is logged into the web-application on the current m/c.
