Jan 3, 2011I have two examples to show you what I want to achieve here. But to point what's different about my question, Is that I'm having a parametrized URLs and I want to implement URL rewriting to my application. But I don't want to convert the parameter in the URL to be placed between slashes..."page.aspx?number=one" to "pages/one/" << NOT!
First example:
http://localhost:1820/Pages/Default.aspx?page=2&start=5
To
http://localhost:1820/Pages/page2
Second example:
http://localhost:1820/Items/Details.aspx?item=3
To
http://localhost:1820/Items/ItemName
But I'll still need all the parameters in the original URLs

HttpHandlers / Modules :: Generic Handler / Prevent Data From Being Written To Live Table Via The Live.aspx Page?
Jun 28, 2010I am using a generic handler (indicator.ashx) to create a graphic that is overlayed from information from a table (called LIVE) from our SQL database. This is working very well and I am very happy with the results.
However I am having an undesirable issue where the query string that is used for this is also being accessed by another page (called ReceiveLive.aspx) which is populating our LIVE table with data when we don't want this. I have been able to track this issue down to our generic handler that seems to populate this table with data whenever the handler is accessed.
The query string that is used to access our graphic through our generic handler is
http://mydomain.com/indicator.ashx?ID=ABC001.
Our other page that writes data to our LIVE database used the query string
http://mydomain.com/live.aspx?ID=ABC001 which is normally only accessed by a small piece of software that sits on the users PC and sends the data when necessary.
My question is this: How do I prevent data from being written to our LIVE table via the Live.aspx page everytime a query string is processed by my indicator.ashx is accessed?
Web Forms :: UserControl Value Is Not Changed When Written Through Code Behind?
May 3, 2010i have one user control which has hiddenField name ='hdnShow' as runat='server'
my scenario is that i have a function in userControl name Show(MessageType);
void Show(MessageType msg)
{
switch(msg)
{
case MessageType.Success:hdnShow.Value= "Success fully saved";
[Code]....
when i execute it and tries to get value of hiddenField thru javascript it still predicts the initial value.
Strange thing is that when i make a textbox in webusercontrol and then try to set its value thru this function.
even the textbox value don't change we can see it on aspx page that value is still the initial one.
some site has asserted that we can do that thru preRender event but it is not working.
may be it is happening coz it is in updatePanel??
yeah i have tried EnableViewstate true and false both condition.

View 1 RepliesWeb Forms :: Can't Download Large Files From Internally Written Site
Feb 1, 2010I've recently been given the task of diagnosing and fixing an internally written asp site that is used to transfer large files internally and externally.
The user uploads a file and enters the receivers email address. The receiver can then click on the link which takes them to the retrieval section of the site.
The issue is although we currently have an upload limit of 100MB set within the web.config file "maxRequestLength=102400", when a user uploads a file of more than 60MB although the upload works and the file is copied to the server when the receiver tries to access it the page simply displays "Internet Explorer cannot display this page".
The site works fine for files that are smaller than 60MB so I don't think it's a code issue, but I can't be 100% certain.

Forms Data Controls :: How To Pass Session Variable As A Parameter To Inline Function Written Inside A Repeater

C# Cookies Not Being Written To?
Sep 23, 2010On my content page I have the code (in page_load):
if (Master.pageAction == "remove")
{
int removeProductID = int.Parse(Request.QueryString["ID"]);
int removeOptionID = int.Parse(Request.QueryString["optID"]);
Master.myBasket.removeFromBasket(removeProductID, removeOptionID);
//Response.Redirect("viewBasket.aspx");
}
The function remove from basket is defined as:
// Removes item from a basket
public void removeFromBasket(int itemsID, int optionsID)
{
Page myPage = (Page)HttpContext.Current.Handler;
this.setCookieString("");
myPage.Response.Write("done");
}
And it calls:
// Sets cookie date
public void setCookieString(string cookiesData)
{
Page myPage = (Page)HttpContext.Current.Handler;
HttpCookie basketCookie = new HttpCookie("basket");
basketCookie["items"] = cookiesData;
basketCookie.Expires = DateTime.Now.AddDays(7d);
myPage.Response.Cookies.Add(basketCookie);
}
I use the setcookiestring function on other pages and it works fine, but this function (removing from the basket) isn't setting the cookie! It is writing "done" to the top of the page, so the functions are executing.
No warnings, no errors, it's just not updating the cookie.

Vb.net - Run A 3.5 Site With Some Pages Written In Classic?
Jan 24, 2011We have a site and a logged in section of the site that all was written in classic asp. We are starting to convert the site pages to asp.net 3.5. We are starting with the easiest pages (text mainly) first then we will rewrite the web application part of the site.
My question is - Is it possible to run the new asp.net 3.5 pages with classic asp pages? Or will we need to rewrite everything before deploying?
Intercept What's Being Written To HttpResponse.OutputStream
Feb 17, 2010I am working on a tool which audits access to existing web application. Existing app does not have any hooks in place, but my plan is to inject an IHttpModule by modifying web.config and log whatever I need to log during EndRequest event.
What I'm struggling with right now is: I cannot intercept what is application writing to an output stream. I need to know what output does the application send to the client. Originally, I hoped I could run a code in BeginRequest to replace HttpContext.Response.OutputStream with a stream of my own, which would be flushed to original stream during EndRequest, but the stream only has a get accessor, so I cannot replace it.
I could of course use reflection to assign to private member of HttpContext.
C# - DataTable Snippet Written Correctly?
Jan 4, 2011public static DataTable GetDataTable(SqlCommand sqlCmd)
{
DataTable tblMyTable = new DataTable();
DataSet myDataSet = new DataSet();
try
{
//1. Create connection
mSqlConnection = new SqlConnection(mStrConnection);
//2. Open connection
mSqlConnection.Open();
mSqlCommand = new SqlCommand();
mSqlCommand = sqlCmd;
//3. Assign Connection
mSqlCommand.Connection = mSqlConnection;
//4. Create/Set DataAdapter
mSqlDataAdapter = new SqlDataAdapter();
mSqlDataAdapter.SelectCommand = mSqlCommand;
//5. Populate DataSet
mSqlDataAdapter.Fill(myDataSet, "DataSet");
tblMyTable = myDataSet.Tables[0];
}
catch (Exception ex)
{
}
finally
{
//6. Clear objects
if ((mSqlDataAdapter != null))
{
mSqlDataAdapter.Dispose();
}
if ((mSqlCommand != null))
{
mSqlCommand.Dispose();
}
if ((mSqlConnection != null))
{
mSqlConnection.Close();
mSqlConnection.Dispose();
}
}
//7. Return DataSet
return tblMyTable;
}
I use the above code to return records from database. The above snippet would run in web application which expected to have around 5000 visitors daily. The records returned reach 20,000 or
over. The returned records are viewed (read-only) in paged GridView.
Would it be better to use DataReader instead of DataTable?
NOTE: two columns in the GridView are hyperlinked.
