hi,
Inside If Not IsPostBack() Then.... End If you have to create the dataset and bind it to that drop down list. Consider the following code:
Dim dsTest As New DataSet<br />
Dim daTest As New SqlDataAdapter("select tid from test", con)<br />
daTest.Fill(dsTest)<br />
<br />
ddl.DataSource = dsTest<br />
ddl.DataTextField = "test"<br />
ddl.DataBind()

How to access C:\ or D:\ with Java script.
|
|
|
|

The short answer: under normal circumstances, you can't.
The browser runs as a sandbox with no rights to the user's local machine. The basic idea is to ensure that no web code can perform actions that could damage the user's machine. Allowing access directly to the client's drives would be a major security exploit. Unless you are developing for a controlled environment, such as your corporate intranet, you really don't want to go down this road.
That being said, there are two ways that come to mind to accomplish it. If you are concerned with IE only, you could write an ActiveX control that has functions to interact with the drives, and manipulate it using javascript. As a cross-browser alternative, you could also create a signed javascript file, and assert that you need local file system permissions.
Hope that helps a bit.

How can I run the routine in ActiveX control through Javascript.
|
|
|
|
|
You will link the ActiveX control into the page using the HTML object[^] tag. At that point, it becomes just another object on the page. You can retrive it using normal javascript DOM techniques, such as getElementById()[^]. Once you have a reference to the ActiveX control, you can access any public members of it.
Hope that helps.

How to navigate through dropdownlist with arrow keys .
Whenever we change the index of dropdown then the SelectedIndexChanged Event Occurs, but we dont want to fire this event on Up and Down arrow keys then what to do?
Also I have another question that - when the focus is on the dropdown and we press CTRL+F4 then dropdown of AddressBar opens Instead of that dropdown.
|
|

|

To navigate the dropdownlist, you'll need to write some javascript to handle the onkeypress event. In that code, you'll want to test for the arrrow keys, and adjust the dropdown list's selectedIndex property. Google has plenty of examples. To get you started, check out:- An example[^] of handling key presses
- An example[^] of working with the dropdown list's options and selected index
As far as the behavior of CTRL+F4, opening the IE address bar is an operating system level decision. I believe that you can capture the keypress, perform your desired action, and not bubble the event using the same technique as above. I haven't tested it, so you may want to give it a try.
Hope that helps.

Set the auto postback property to false. This will stop the post back event from getting fired.

Hi guys,
i am transforming an file called XMLFile.xml along with the appropriate xslt file
like this:
XPathDocument surveyDoc = new XPathDocument(Server.MapPath("XMLFile.xml"));
// Load the xslt to do the transformations
XslTransform transform = new XslTransform();
transform.Load(Server.MapPath("dynamicControls.xslt"));
// Get the transformed result
StringWriter sw = new StringWriter();
transform.Transform(surveyDoc, null, sw);
But the xmlfile.xml contents are like:
<formname name="BusinessUnit">
<contol type="text" name="BuisnessUnit" value="FirstName" required="yes">
<contol type="text" name="Code" validation="true" value="LastName" valtype="numbers">
<contol type="text" name="LegalEntity" value="EmailId">
<contol type="text" name="Place" value="DOB">
<contol type="text" name="DateOfBirth" value="BusinessUnit">
followed by another form details.
<formname name="foreign unit">
details
so i want to specify the required formname in new XPathDocument=(Server.MapPath("XMLFile.xml")); //i.e BusinessUnit for ex: not the entire
xml file how can i pass only the required xml content(i.e only a part of the xml file containing required form details) want for transformation.I.e i dont want to transform foreign unit part also within the xml file.Please throw some light on this.
Thks in advance,

Hi all

1) System.Net.Dns.GetHostByAddress(System.Net.IPAddress.Parse(System.Web.HttpContext.Current.Request.UserHostName)).HostName
2)System.Net.Dns.GetHostByAddress(Request.ServerVariables.Item("REMOTE_HOST")).HostName()
3)Request.ServerVariables("REMOTE_ADDR")
4)HttpContext.Current.Request.UserHostAddress.ToString
5)HttpContext.Current.Request.UserHostName.ToString
but i get Te IP:10.0.0.3 for all visitors.
Can anyone help me please and what is the problem??
thank all

Rather then trying to invoke a DNS lookup, have you tried using the UserHostAddress property of the Request object?
For example:
string clientIP = Request.UserHostAddress;

Hi
yes sir i used Request.UserHostAddress but the result was that and that was like other codes. and sorilly i can't find real IP Address. where is the problem???

Hrmm... I'm not sure that we have enough information about your environment to help here. It may be helpful if you describe the hardware and software setup of your environment in greater detail.
If the standard means of retrieving the visitor's IP address are failing, I'd speculate that there is some kind of environmental issue here. If you have a load balancer, firewall, or proxy forwarding traffic to your server, you may wish to start your search there. Are they configured to send the actual request IP along?

How to change the ToolTip message in a calendar for specific dates only.
Is there an event that detects if the mouse is over that date so I change the ToolTip value.
Mohamed El Gohary

Two options:
+ Override the Render method, and replace the default setting for the ToolTip in the Title attribute of the A element with your own value.
+ Create a DayRender event handler, make the default LiteralControl of each cell invisible, then insert a new hyperlink/linkbutton which allows you to set the Tooltip.

| Okay, before you accuse me of saying that I should have looked around better let me say that I already have ASP.NET working perfectly, no problems with ASP.NET pages. However, I'm trying to get a plain old ASP site to come up on the same server to no avail. I have confirmed that I have the asp.dll file, and I have registered it. I can display a simple index.htm from this folder, so IIS can actually see this folder. Any suggestions? Last modified: Saturday, July 15, 2006 1:11:55 PM --

If you have Norton Antivirus installed on your machine, you may have to disable "Script blocking". Otherwise ASP doesn't work.
