View 2 RepliesI have my app running on asp.net 4.0 and IIS 5.1.
I'm having problems running IO functions on my PUBLISHED website, on the server running IIS. I can run everything just fine on my own machine without any issues in debug mode.
I pinpointed the errors to some IO functions Im trying to add.
Example:
StreamWriter sw = new StreamWriter(outputfile, true);
sw.WriteLine(DateTime.Now.Date.ToString());
or
File.Copy(sourceFile, destinationFile), true);
When I add something of this nature.. I get the generic runtime error (since I'm not sure how to make it show more specific errors at this point)
I was thinking it has something to do with a security issue. But, Im not sure where to look.
I have an ASP.NET control (a button) in a WebApp. It has an onclick attribute:
onclick="SaveButton_Click"
SaveButton_Click()
is a C# function in the codebehind file. When the user clicks the button, SaveButton_Click() is executed.
What I would like to know is whether there's a way to set up a javascript callback junction. I know how this is done in AJAX, but I'm not sure in ASP.NET (with controls that run on the server) how (or if) this can be done.
For protect against XSS we should make all input from textboxes thoht Server.Htmlencode function.
1) If i let a input go thorgh Server.Htmlencode and save it in database. But what happen if i letter show this input data from database on browerser ...if database input data have <script> it will then make Xss!!!!.
2) I use Server.Htmlencode.. and the user write <b>ss<b>... (label.text = userinput.text;) and i WANT to show ss in browser. What shuld i do for make this happen ??
Is there a way to run server side functions by javascript? There are two things I need to do:
1. Either emulate clicking a link/button, or calling the OnClick function directly (not OnClientClick)
2. Control the back and forward control of the wizard control by using the keyboard

I am trying to display this query result in an aspx page.
It is very slow in loading. Here is the query. The inner query inside the outer quesry is the problem.(Please see the underlined part in the query) - (If I remove that part it is very fast.)

Trying to get a query going in SQL server but I get bad/ errors in the query.I have a 2 tables. One is the "Project" table while the other is the "Task" table.Table structure is as follows.
Project table => ProjectID,ProjectName
Task table => TaskID, TaskName,ProjectID,Quarter, Hours
A project can have many task. The ProjectID in Task table is the foreign key which reference the project ID.What I need to do is to SUM all the hours in the Task table and group it by quarter and then group it by ProjectID. Output of the SQL should be in the form of projectID,Quarter, Hours.

View 2 RepliesI have the following query that uses a linked server that is on a different VLAN of our network:
[Code]....
It works fine in Query Analyzer but when I put it into Visual Web Developer 2008 Express as a SQL Data Source I get an error:
"OLE DB Provider 'MSDASQL' reported an error. Authentication failed."
In order to terminate a SQL Server query within a VB application, we use the Dispose method to close and dispose the database connection. That has been the only way we have found to actually stop a query from running and release the resources.
However, the next time a new connection is created to the same database, we are getting the error "'ObjectDisposedException - Safe Handle has been closed.". It seems like it is always trying to reuse the disposed connection from the connection pool, and it is not reinitializing it. By using a different connection string, we can avoid the error, since now it's not using the connection pool. But there must be a better way to either stop the query or to reinitialize the disposed connection.
is this correct:
select * from tablename where xyz like 'dan%' and like 'bill%'
i want to list entries where xyz is daniel, bill steffen.....
for some reason i am always getting an incorrect syntax error in the following queryI have tried 2 ways to write this query and both failed, Query 1:
[Code]....
Query 2:

it is possible to make 2 functions with the same name (and the same overload.. lets say both doesnt get anything in and return an action result)in the same controllerone for t
ne for get
consider the follwing table, this table actually shows which id was given a new id
i.e 11 was assigned 13
again 13 was assigned 15
15 was reassigned 17....and so on actually 11,13,15,17,19 represent the same user (hope u understood)
customerId rejoiningId
11 13
13 15
15 17
20 21
17 19
48 50
21 25
i need to loop through all the rows and find the relation that which all ids are interlinked
say the user enters the rejoining id -13,hence the result should come out to be as 11,13,15,17,19
if user enters 21result should be 20,21,25
it takes a bit of looping statements in query that i couldnt figure out
i have a big query and many data
when i try to execute this query i got this error
how can i run this query complete?
I am new to development and want to know the professional way to deal with dates in SQL Server. In my applications mainly we deal with the DATE datatype and no concern with time part. Also maintaining the format dd/mm/yyyy So for example if I have the table with the following structure.
EmployeeTable
---------------
emp_id int
emp_name varchar(50)
join_date date
and if I want to query "join_date" in between start date and end date and pass the dd/mm/yyyy as stored procedure criteria and want to query.What is the professional way to handle dates? I always convert date in varchar and then do the comparison which I guess is the unprofessional way of doing it.
What's wrong this T-SQL query :
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SQLData As New System.Data.SqlClient.SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True")
