You can use the Request object to get a decent amount of information from each user.
e.g.
C#
bool hasCookies = Page.Request.Browser.Cookies;
VB
Dim hasCookies as Boolean = Page.Request.Browser.Cookies
Hope this helps!

Row_Updating not updating old value with new value
Pls how can i update the datatable with the newly entered values in the gridview? Also i want to disable the Keyfield, the first column from being edited by the user
See my code below
Protected Sub grdPhases_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles grdPhases.RowUpdating
If Not Session("biddetail") Is Nothing Then
oDT = Session("biddetail")
End If
grdPhases.DataSource = oDT
If e.NewValues("PhaseCost") IsNot Nothing Then
e.NewValues("PhaseCost") = Decimal.Parse(e.NewValues("PhaseCost").ToString(), Globalization.NumberStyles.Currency)
Else
lblPhaseCost.Visible = True
e.Cancel = True 'cancels the operation being performed
End If
If e.NewValues("StartDate") IsNot Nothing Then
lblPhaseCost.Visible = False
Else
lblPhaseCost.Text = "Enter the Start Date for this phase"
lblPhaseCost.Visible = True
e.Cancel = True 'cancels the operation being performed
End If
If e.NewValues("EndDate") IsNot Nothing Then
lblPhaseCost.Visible = False
Else
lblPhaseCost.Text = "Enter the End Date for this phase"
lblPhaseCost.Visible = True
e.Cancel = True 'cancels the operation being performed
End If
If Not IsDate(e.NewValues("StartDate")) Then
lblPhaseCost.Text = "Invalid Start Date"

End If

e.OldValues.Item("StartDate") = e.NewValues.Item("StartDate")
e.OldValues.Item("EndDate") = e.NewValues.Item("EndDate")

How can i increace session time for avoiding session expire.
One only darshan shah
|

In your web config file you can set the session to timeout longer then the default of 20 minutes:
<sessionState
mode="[Off|InProc|StateServer|SQLServer|Custom]"
timeout="number of minutes"
...
/>
If you have long running processes that you are trying to run in asp.net you will run into other problems as well. There is also a timeout for the iis worker process. So if you are doing some processing that takes a long time to run and doesn't return to the web page, you could run into this worker process timeout as well. You have to set this in the IIS configuration manager. If your app is a long running process, it might be a good idea to write a windows app instead so you don't run into timeout issues.
Hope that helps.

Hi All,
I am developing a website using asp.net 2.0 and MSAccess.
it in under construction, but I want to test it.
It is for intranet purpose only,.
My application runs only when I open Visual Studio -> start debugging
If I stop debugging and close the Visual Studio, the browser shows "The page cannot be displayed".
How can I run it from another pc in my intranet ( for MSAccess as backend )
Any help is appreciated.
Thanks
Bye

You can't.
Quite correctly, things are set up so that you, as a web programmer, can't do things on the user's machine without them allowong it - imagine if you could do what you want: you'd find web-pages suddenly sending out all sorts of nonsense to your printer - advertising gibberish, porn.. all sorts...
And anyway, the user may want to select print settings first - page size and type, draft or print mode etc
cheers

Hello All,
I'm getting the following error message in my ASP program.
Microsoft VBScript runtime error '800a0046'
Permission denied
/monthly/holdingsMD.asp, line 141
Previously this code is working fine on a different machine for years. Now we shifted this application to a new machine and got the above error message when we tried to insert some values from a file. The other pages in this application are working fine on the new machine (these pages are retrieving data from database.)
Here is the code were I’m getting the error message:
--------------------------------------------------------------------------------
set myfile=Server.CreateObject("scripting.filesystemobject")
Response.Write holdingspath &" "&mktdatapath& "transaction updated
"
'******** Inserting Market data into tbl_mktdata **********
if mktdatapath <> "null" then
'mktdatapath="f:\monthly reports\holdings\01062006.MD" 'Server.MapPath()
set genfile = myfile.OpenTextFile(mktdatapath,1) -->This is line 141
ObjCon.Execute "delete from tbl_mktdata" 'delete previous contents from tbl_mktdata
--------------------------------------------------------------------------------
FYI: This application is running on our local system. With Windows XP Prof. And IIS configured.
Please let me know what is the possible reason for this error.
Many Thanks!!

hai all please clarify mny doubts

As it says: "Permission denied" - You need to get in touch with the administrator of that machine and ask him/her to give your application WRITE permissions on the folder where the files are that you want to write to.
cheers

Hi Fred,
The folder, in which the files were there, has all permissions granted to the user . (The user is having full control over the folder.) But still I’m getting the error message.
Please help me; your feedback is greatly appreciated.
Many Thanks!!

You have commented out this line:
'mktdatapath="f:\monthly reports\holdings\01062006.MD" 'Server.MapPath()
So where is the line where mktdatapath is set? Perhaps you have a) not set it at all or b) left it hard-coded pointing to your local machines path.

Fred,
That line of code was commented out.
Here is the full code we are using.

As the code worked well before in previous machine I think it error is because of settings in IIS. But I’m not sure of it.
