What does this have to do with Session.Abandon removing the keys?

No, it doesn't.
It marks the Session object for removal. When the request finishes, the entire Session object is removed. The items are never removed from the Session object.

Sonia Gupta wrote: i am using the following code
Session["Sonia"] = "11";
Session["Sonia1"] = "12";
Session.Clear();
it renders the Session["Sonia"] and session["Sonia1"] to null.
Actually, it removed the items. If it would just set the items to null, the Session.Count property would still return 2, but clearing the session items makes it return 0.
Sonia Gupta wrote: Session["Sonia"] = "11";
Session["Sonia1"] = "12";
Session.Abandon();
leaves the session["Sonia"] AND Session["Sonia"] AS IT IS.
Yes. The current session can't be removed until the current request is completed. That would be sawing off the branch you are sitting on.

public void generateTabularStructure(DataSet dsItems, HtmlTable tblTemp)
{
DataView dvItems = dsItems.Tables[0].DefaultView;
HtmlTableRow trTemp;
HtmlTableCell tdtemp;
for (int i = 0; i < dvItems.Count; i++)
{
HtmlTable objTable = null;
objTable = getArticleTable(dvItems[i]);
if (i % 2 == 0)
{
trTemp = new HtmlTableRow();
tblTemp.Rows.Add(trTemp);
}
tdtemp = new HtmlTableCell();
trTemp.Cells.Add(tdtemp);
tdtemp.Controls.Add(objTable);
tdtemp = new HtmlTableCell();
trTemp.Cells.Add(tdtemp);
tdtemp.InnerHtml = " ";
}
}
The above code when compiled gives error message
Use of unassigned local variable 'trTemp'
at the line which is bold
but for value i = 0 'trTemp' would be initialized in the if syntax before it is used so the error should not appear
any justification for this compilation error

This is a compilation error. You have described a condition where the value is set at runtime, which the compiler can't know about.
To get round this, change your code to include the following:
HtmlTableRow trTemp = null;
HtmlTableCell tdtemp = null;

I have 2 Excel files...
1. the original Excel file that was given to me to be converted to a dataset and so I could fill up the SQL Database.
2. the other is the one I retrieved from the database and then generated into an Excel document. used a similar procedure
to that of the tutorial here... a low-tech version of generating Excel files... using the XML spreadsheet style in one of the tutorials...
I open both Excel files (the original and generated excel file) and they look identical and they even contain the exact same data in each cells...
now here's the problem...I need to make a method that checks whether or not they're equivalent or not to see if any data is lost since checking each
cell of a large excel file would take a lot of time...
so I use OleDB that comes with C# Express since we're not suppose to use any 3rd party dlls...
for a temporary method to test whether they're equal is, I try to convert the 2 excel documents to 2 datasets and then compare the two generated datasets
whether or not they are equivalent to each other...
public static DataSet Method()
{
string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=FILE_PATH;Extended Properties=""Excel 8.0;HDR=YES;""";
OleDbConnection conn = new OleDbConnection(connectionString);
OleDbCommand cmd = new OleDbCommand("Select * from [Project List$]", conn);
cmd.CommandType = CommandType.Text;
OleDbDataAdapter myAdapter = new OleDbDataAdapter(cmd);
DataSet ds = new DataSet();
try
{
myAdapter.Fill(ds);
return ds;
}
catch(OleDbException ex)
{
throw ex;
}
}
the original converts to a dataset with no problem but when I try to convert the one generated from the database is catches an OleDbException...
OleDBException was caught:
External table is not in the expected format.
how come? and is there any word around to this problem without using any 3rd party dlls? or downloading any additional dlls from Microsoft?
so we tried another method... used XmlDocument to get the dataset... and then compared it to one another and yet they were not equal? any suggestions?

You are getting the exception because the excel file is in xml format. It should be in native xls file format for OleDb to work. You can use Excel object model to convert the xml file to excel format. I have described it here: Excel[^]

I get the following error message when trying to run my tests (ctrl-shift-X) :
"column 'TestType' does not belong to table test".
Has anyone found a workaround for this ?

This seems to be an issue with TFS (and possibly the testrun.config file0. To work round it, create a new test project and run with that.

Are you running the tests on Vista? There seems to be some issues with this.
I got the answer to my problem on this[^] thread.

I'm running it on XP.
I tried : Create new C# test project, reload, no joy.
Then : Create VB test project, reload original C# project, joy.

The problem is when I close the port my program hangs. When I close the serial port, or the form, my program throws an exception, after hanging for a while.
Basically it hangs whenever I call SerialPort.Close();
Help would be greatly appreciated 
|

|

can you post some code? do you have any program loops reading input from the port? what is the error exception.message?
If it' stuck, DO NOT pull harder!

Hi all,
Any one help me in .NET deployment. I am deploying an project which was created using c# 2005. In this i want to ask the user to enter for an serial key.

How to do this. plz giude me....

Need some clarity here, are you trying to come up with your own way of creating serial keys for your project?
