when i try to access controls from parent page to child page it shows error like "windows.opener.document" is null. How to overcome this problem?
|
|
|
|
|
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.
Even like Round, abs also will come from database all the expression are evaluates and giving values except IIF....so how to resolve this..

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)...
Evaluate Arithmetic Expression using Polish Notation Login in VB.NET 2005[^]

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 ?

can you please provide the code (specially when you are making the connection using ODBC)
|

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.

hi all,
i have search on net but not satisfied with ans...can anyone tell me that property or data of 1 page's viewstate can be used in another page?
Thanx
|
|
|
|
|
ViewState cannot be shared between pages. It is specific to a page. Use Session object to share data between pages.
|
|
|
|
|
thanx
but some people telling by server.transfer we can share data....i got that kind of ans from many forums....
some are saying no and some are saying yes..........so i m bit confuse on that..........
|

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.

What the State Management Types?
Client-side state management stores information on the client’s computer by embedding the information into a web page (Hiddenfields), URL (Query strings) or a cookie.
1. View state.
2. Control state: If you create a custom control that requires view state to work, you should use control state to ensure (يضمن) other developers don’t break your control by disabling view state.
3. Hiddenfields: hidden fields store in HTML form without displaying it in the user’s browser.
4. Cookies: cookies store a value in the user’s browser.
5. Query strings: query string stores values in URL.
Server-side state management stores information on server’s memory.
1. Application state.
2. Session state.
3. Profile Properties.
4. Cache state.
What the disadvantages are of ViewState?
- Disadvantages of ViewState:
1. The more controls you have on the form the larger the size of ViewState and the larger the size of the HTML you send back and forth to the server.
2. Only works when pages postback to themselves.
3. You can't persist (تحفظ) data to other pages.
