There is spelling mistake.
Use:
window.opener.document

This you can use only for those popups which has been opened by using "window.open()" function.

hi,

i cannot convert string to int,

dim strExt as string
strExt = 10 + 20 + (iif(20 > 30), 40, 50) + 50

int complexsum = strExt
string str = complexsum.ToString();

its giving convertion error i tried to convert also...

Note :

This "10 + 20 + (iif(20 > 30), 40, 50) + 50" Expression is comming from database , so i copid to string then am trying to eveluate.

Hi,
You cant evaluate an expression like this directly in .Net.
You have to create your own function using some algorithm like Polish Notation to evaluate arithmetic expressions.
I have submitted an article for this just follow this link...
this is very poor explanation but this code will help you alot (I think)...

Hi, i have developed one website. When i try to run it from VS 2005 it runs fine. I hosted the website in my local machine instead of running from VS 2005. It also works fine for 2 to 3 pages. But its getting error in one page where that page reads data from csv file using odbc connection. I am getting error as "IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
" while executing diretly instead of vs 2005. The same page executes fine when i run from vs2005.
What's the thing i need to do to execute in other way ?

Note: This works fine when i run the applicaiton from vs 2005. But only getting problem while i am running the application by hosting it on same machine.

if (_fileexten == ".csv")
{
string str = Path.GetFileName(_filename);
OdbcConnection conn = new OdbcConnection("Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=" + _fpath + "\\;Extensions=asc,csv,tab,txt;Extended Properties=\"HDR=YES;IMEX=1;\";Persist Security Info=False");
conn.Open();

string sql_select = "select FirstName, LastName, MiddleName, Zip from [" + str + "]";
OdbcDataAdapter myCommand = new OdbcDataAdapter(sql_select, conn);

myCommand.Fill(myDataSet, "csv");
dt = myDataSet.Tables[0];

conn.Close();
myCommand.Dispose();

}

It seems a bit weired problem. Check the ODBC configuration for all the available drivers, and check whether the Microsoft Text Driver is installed on the machine or not. You will find the ODBC Datasource ADministrator from Administrative Tools.

ViewState cannot be shared between pages. It is specific to a page. Use Session object to share data between pages.

Using Server.Transfer you can not redirect to a different from the server itself.
Example if your server is www.yahoo.com you can use server.transfer to move
to www.microsoft.com but yes you can move to www.yahoo.com/travels, i.e.
within websites. This cross server redirect is possible only using
Response.redirect.
