Hi,
We have developed an (ASP.NET) Web Application in VS 2008 & developed a setup project for the same and successfully installed in our local environment (Windows XP/ Windows 2003 server).
This web setup project contains the below:
1. Web Application (Primary output/ Content)
2. Primary output of BLL & DAL
3. Few custom actions
4. Few UI Forms to get the Database details/ etc from user
5. One Windows service
This setup fails immediatley in the client environment. The client also using the Windows XP SP2/ 32 bit version. But the windows root folder is "C:\WINNT"; bcos the system has been upgraded from Windows 2000 to XP it seems.
After that we have removed the custom actions and Windows service from the setup project (to narrow down the issue) & tried to install, it also failed.
We dont have any clue on this. Can you please help...
Thanks in Advance !!

What have you tried ? How much do you know about the languages you're using ? What do you think the solution might be ?
Seems to me like the most likey solution is to use some string mashing to extract the value, or a regex.

Then this task is way too complex for you. You should abandon it, and spend some time learning basic exercises instead. Except you're being paid for this code, right ?

Use this :
cmd.Parameters.AddWithValue("@ChooseThumbnail", rbtnthumb1.SelectedValue)
If you call
SelectedItem.Text
it will return the innerhtml under the listitem.
On the other hand if you call SelectedValue, it will return the value attribute assigned in asp:ListItem.
Hope you like it.
Another thing it is better to write like
<img src="images/Video97.gif" alt="Video" align="absmiddle" />
You havnt closed any img tag using /> on the right.

How to get live stream from webcam in our web page?
|
|
|
|
|
You can't do that with ASP.NET. You can do it with HTML. What have you tried ? Did you search the web for info at all ? Where is the webcam, on the server ? You can create a stream and set up windows media player to display it.

AFAIK, live stream can only be captured using some windows client...
or any plugin which allows direct access to webcam devices.
I dont know if Flash / Adobe AIR / Silverlight plugins allows you to capture live streams from browser. If they cant, you need to create your own browser plugin.

This was my code to display live streaming from webcam.
hope thi will work for u.
u need to install the webcam and than place this file in ur initpub folder
to share the images on web and allow the user to view it.
u also need to install latest version of media player and windows media encoder.
<object id="MediaPlayer" width="176" height="144" classid="CLSID:22D6f312-B0F6-11D0-94AB-0080C74C7E95" standby="Loading Windows Media Player components..." type="application/x-oleobject" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,7,1112">
<param name="autoStart" value="True" />
<param name="filename" value="http://localhost:8080" />
<param name="ShowControls" value="False" />
<param name="ShowStatusBar" value="true" />
<embed type="application/x-mplayer2" src="http://localhost:8080" name="MediaPlayer" width="176" height="144" autostart="1" showcontrols="0" />
<object id="Player" width="300" height="250"
classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6">

Ive an Obout calender that i change its datemin , datemax according to Dropdownlist selected item, i want the textbox (that the calender copy its value to ) to be clear(empty) when the DDL changes for the user to select a new date ,DDl is AutoPostback true ,ive tried this in the [ddlVacationTypes_SelectedIndexChanged]:
TextBox1.Text = "" 'Didnt work the textbox is holding the last value
i also tried this in the [Page_Load]:
Page.RegisterClientScriptBlock("MyScript", _
"<script language=javascript>" & _
" document.getElementByID('TextBox1').value = '' ; </script>")
'Didnt work the textbox is holding the last value
what am i doing wrong? + How to fix this?

You might be setting it up on page_load :S
Please don't forget to mark 'Good Answer', if you find it really a good one!

Have you stepped through the debugger ? If you're using a third party control, perhaps it is what sets the value ?
alaminfad wrote: " document.getElementByID('TextBox1').value = '' ; ")
That won't work. Perhaps if you used the right client side ID, it might.

And also before you run a script check if the script block is already exists in the page.Do like this :
if(!this.ClientScript.IsClientScriptBlockRegistered("MyScript"))
{
Page.RegisterClientScriptBlock("MyScript","<script language=javascript>" & _
" document.getElementByID('" + TextBox1.ClientId +"').value = '' ; </script>")
}
Also make sure you are not doing this every time the page is posted back. Always check :
if(this.IsPostBack)
{
}
inside Page_Load
Finally, if you make TextBox as serverside, you can set the value inside ddlVacationTypes_SelectedIndexChanged by just calling
TextBox1.Text = ddlVacationTypes.SelectedValue
It must work.

Unfortunately it did'nt work ,i do want this every time the page is posted back , i mean when the user select from the DDL the textbox1 should be empty for him(user) to notice and select a date from the Obout calender image , i tried it both ways(if and if not is post back) it didnt work , i found this property Clear() on the Obout tutorials :
**************************************************
If you need to clear the current selected date simply call the method Clear.
Example:
<obout:Calendar runat="server" id="myCal">
</obout:Calendar>
<a onclick="myCal.Clear();">
Clear
</a>
***********************************************
by the way ive two page loads
one page_load in the user control where the DDl and obout Calender and of course its Textbox which we want to clear
Second page_load in the actual default page
so ive tried to use that property in both page_loads it didnt work ,i have follwed the debugger it going in the right way , here is the code
-----------------------------
Dim script As New StringBuilder
' Dim reader As StreamReader = File.OpenText(Server.MapPath(includeFilePath))
If Not Page.ClientScript.IsClientScriptBlockRegistered("MySript") Then
'script.Append(reader.ReadToEnd.Replace("{title}", Me.Title).Replace("{buttonLabel}", Me.ButtonLabel))
' delay alert 1 ms to handle postback
script.Append("<script language='javascript'>document.dfghsdfggetElementByID('Calendar1').Clear();</script>")
Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "MySript", script.ToString)
End If
--------------------------------------------------------------------
one more thing the server doesnt seem to validate what inside the script even if write
Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "MySript","Nothing")
what is a problem? + how to fix it?
