hi
im doing an asp.net website with a login system for its users. i used a table in sql to maintain a record of user details.when a user logs in , i set a flag to 1 and when they click the logout button , the flag is set back to 0. my problem is if the user closes the browser window or for some reason the system crashes , that user still remains logged in. i have 2 go to the database and set the flag. please suggest some way to solve my prob. thanx

There are many ways to do this.
1 - Handle the session_end event and reset the DB flag there. This event gets fired when session timed out and will happen even user closes browser (not immediately). Works only on InProc session mode.
2 - Create a new column in table which has the user's last request time. Write a SQL job which runs frequently, checks the last request time and update the flag if necessary.

Hi
You excuse my ignorance on this, but I am looking for someone to help me with the Object Tag or Active X to put it another way!
What I am trying to do is to display a word doc in ASP.Net, but I am unable to do and none of the examples I have found on the Internet work. So, can someone kindly assist me by talking me through what to do? Is there some other control that I need to install or plug in I need?
Thank you

Are you binding the grid in page_load and binding without checking IsPostBack?
Learner520 wrote: (String) ((TextBox)xItem.FindControl("TxtForeName")).Text;
This is bad practice. If your item can't be found, this code will crash. First find the control, do NULL checking and ensure you have a valid object before you access Text property on it.

Hi,
I want to develop a stored procedure in which I have to apply different modifications to the Query. Finally after undergoing all the changes to the query I have to execute the final query and get the resultant table.For example:
Create Procedure [dbo].[Test]
@Flg1 bit,
@Flg2 bit,
@Flg3 bit,
AS
BEGIN
SET NOCOUNT ON;
Declare @Query varchar(max)
if(@Flg1<>0)
Begin
Set @Query='Select * from emplayee where empId=1"
End
if(@Flg2<>0)
Begin
Set @Query=@Query+'and empId=2'
End
if(@Flg3<>0)
Begin
Set @Query=@Query+'and empId=3'
End
Exec sp_executesql(@Query);
End
As shown above my Query conditions will change according to the parameters. But here I am not able to get the resultant table. Please reply me if anyone know how to get the resultant Table. Also please tell me whether the above procedure is correct or not.
Thanks in advance.

Hi,
You have mistakes ...
Nekkantidivya wrote: Set @Query='Select * from emplayee where empId=1"
You have ended up with double quotes.
Nekkantidivya wrote: Declare @Query varchar(max)
Replace 'max' with some number like 200 as your string cant go over this.
Correct it n then check.

Create Procedure [dbo].[Test]
@EmpID Int
as
AS
BEGIN
SET NOCOUNT ON
Select * from emplayee where empId <= @EmpID
END
You better ask these question in the SQL part of this forum. They'll give you more proper answers.
In Word you can only store 2 bytes. That is why I use Writer.

Please forgive the expressin error in this message, I am not good at English
I must get the instance reference of a running MS WORD progress in my asp.net webform, I tried
to use Marshal.GetActiveObject() like below，But it throws a exception like "....UNAVAILABE"
----------------------------------
Object wordApp = Marshal.GetActiveObject( "Word.Application" )；
----------------------------------
I have found by google a discuss thread below for a same question like me, but it seemed not give an answer at last.

Your question is not clear. Are you trying to get a process handle of MsWord? If yes, is this process running on server?
|

N a v a n e e t h,
Thank you very much for your help and sorry for my not clear question
The MsWord process is running on server and it has openned some doc file, and now I'am try to interact with the MsWord process in my ASP.NET application. So I tried to use GetActiveObject to get a objec reference to the MsWord process. But it just throwed a exception.
And the GetActiveObject（）can work well in a C# WINFORM application, while not in an ASP.NET application.
I think the discuss thread I mentioned above in my question may gave the possible reason of this quesion. Here is the abstract of the post:
---------------------------------------------
Hello,
Based on my research, GetActiveObject obtains a running instance of an
object from the running object table (ROT). Each WinStation has it's own
ROT. The interactive desktop is one WinStation and has it's own ROT and
that is where the desktop application will have registered the running
object. The ASP.NET process is running under a seperate account and exists
in a non-interactive WinStation with its own ROT. That is why it fails.
I think the only way for this to work would be to launch the third party
application process from ASP.NET so it exists in the same WinStation. Of
course the application will then not be visible and the user cannot
interact with it.
--------------------------------------------
Thanks a lot

Thanks for the explanation.

This could be the reason why it is failing. BTW, whatever you are trying looks odd to me. If you can tell us why you are doing this and what is the expected behavior, there may be better solutions.

Navaneeth,
Thank you so much for your help and sorry for my late reply now.
Actually, I'm not really need to let my ASP.NET app to interact with "MsWord", instead, it's an ole server we developed by VC++ by ourselves. Due to my poor English and to express the question here easily, I used "MsWord".
The ole server's duty is doing some special tasks on our server, let's call it "MY-OLE-SERVER" below. MY-OLE-SERVER is running as a sperate process. And we have an another C# WINSERVICE app to comunicate with it. This is not the problem, it's ok for the WINSERVICE app to use Marshal.GetActiveObject() to get reference with MY-OLE-SERVER. But at the same time, our ASP.NET app need to make some deal with MY-OLE-SERVER also and as you know, it's just not running ok.
So do you have any good suggestion for our problem?
Thank you again
