First of all, this is not the correct place to write progressbar related question. Well, I think your question will be better to ask in Windows forum.
Well, I think you need to create a new thread to invoke the function. You create an event within the class which have the function.
Now you raiseevent while running the function.
Now from the caller Invoke the function from the thread. Before doing this add an event handler to the code which will be called whenever an event is raised.
Thus you can handle the event and show the progress bar.
You can also make use of EventArgs and define a custom class of yours which will be sending the percentage complete value to the eventhandler.

Hi Everybody:
I am a new comer to web development. I have a problem when developing my ASP.Net application.Here is my code:
<br />
<table id="Header" cellpadding="0" cellspacing="0" border="0" width="100%" runat="server" EnableViewState="False" ><br />
<tr><br />
<td valign="top"><br />
<asp:Image EnableViewState="False" GenerateEmptyAlternateText="True" ID="Image1" runat="server" <br />
ImageUrl="~/Images/TopLeftCorner.png" Width="6px" Height="6px" /><br />
</td><br />
<td valign="middle" style="background-color: #F1F1F1;width: 100%;"><br />
</td><br />
<td valign="top"><br />
<asp:Image EnableViewState="False" ID="Image2" runat="server" GenerateEmptyAlternateText="True"<br />
ImageUrl="~/Images/TopRightCorner.png" Width="6px" Height="6px" /><br />
</td><br />
</tr><br />
</table><br />
<table id="Content" border="0" cellpadding="0" cellspacing="0" width="100%"><br />
<tr><br />
<td valign="top" style="background-color: #F1F1F1; "><br />
<asp:contentplaceholder id="ContentPlaceHolder1" runat="server"><br />
</asp:contentplaceholder><br />
</td><br />
</tr><br />
</table> <br />
<table runat="server" id="Footer" border="0" cellpadding="0" cellspacing="0" width="100%" EnableViewState="False"><br />
<tr><br />
<td valign="top"><br />
<asp:Image EnableViewState="False" GenerateEmptyAlternateText="True" ID="Image14" Height="6px" Width="6px" <br />
runat="server" ImageUrl="~/Images/BottomLeftCorner.png" /><br />
</td><br />
<td style="width: 100%; background-color: #F1F1F1;"><br />
</td><br />
<td valign="top"><br />
<asp:Image EnableViewState="False" GenerateEmptyAlternateText="True" ID="Image13" Height="6px" Width="6px" <br />
runat="server" ImageUrl="~/Images/BottomRightCorner.png"/><br />
</td><br />
</tr><br />
</table><br />
The display result of these code is: The cells that contain images have a greater height than 6px(that is my images height),and the images diplay in the middle of the cells(vertically). This causes the "Header","Content" and "Footer" be separated.That is what I not want to see.
Is there any way? Any ideas will be appropriate.

Give your table rows a height of 6px. (style="height:6px;")
Your question title could use a little work... I reckon we can all figure out this is an asp.net question, given that this is the asp.net questions forum...

Hi everyone,
I have a DetailsView where the records are DateTime. Of the DateTime, I am only interested in the date part. I can not show the time when viewing records in the DetailsView, but when you click Edit, the full DateTime is shown (the date + 12:00:00 AM). I have a RegEx validator on it because I don't want the user entering a time. Does anyone know how to not show the time part of the DateTime when editing on a DetailsView?
Thanks!

if you use the Bind syntax it takes a 2nd parameter which is a normal .NET formatting string.
ie/
<%# Bind("FieldName","dd/MM/yyyy") %>
|
|
|
|
|
Thanks a lot. I just found the ApplyFormatInEditMode property, too.
|
|
|
|
|
You can use the DataFormatString property of the column, and/or select just the date part from the database to begin with (SQL syntax of which depends on your databse)
|
|
|
|
|
That works when displaying, but when you click Edit, it shows the date+time in the box. But couple that with the ApplyFormatInEditMode and it works. Thanks!
|

U can store only DatePart in Database . Try This
declare @datepart varchar(10)
set @datepart = convert(varchar(10) ,getdate(),101)

Many way to solve this problem.
1. In SQL select statement use the Declare variable with 50 length. and assign db value to that variable. and bind the same variable to grid(do string.concat(variable,"...").
2. At DataAccess layer, bind your entity variable with substracted value of DB value.
ETC....

Comment on Correction. Store it on a Session Variable and Clear it when you are done with it.
Hope this helps

Just store it in a session and then retrieve on postback.

If you mean that you want to put the password back into a password input field after postback, that is not possible. You can't set the value of the field programmatically, neither in the html code nor using client script. The only way that anything is put in the field is by user input.
You can keep the entered password in a session variable, but you have to show it in another way on the page. You can for example show a text like ******* representing an entered password, and if the user clicks on the text to change it, you can display a password field.
Despite everything, the person most likely to be fooling you next is yourself.
