This is regarding GetPreloadedEntityBody() function of HttpWorkerRequest class . I am using this method to get perloaded data of requested page. but GetPreloadedEntityBody() function alway returns me null value , while same code is working for server with IIS6.0
1) I have Application_PostAcquireRequestState event . on which i do all user releated validation.
2) After Sucessful validation i am creating object like below code snippet of worker process.
Dim hwr As HttpWorkerRequest = CType(context.GetType.GetProperty("WorkerRequest", Reflection.BindingFlags.Instance Or Reflection.BindingFlags.NonPublic).GetValue(context, Nothing), HttpWorkerRequest)
3) AFter That checking where request has body or not and the calling GetPreloadedEntityBody() which is returning null alway for IIS7.0 ,while in IIS6.0 same code is working fine.
if hwr.HasEntityBody Then Dim preloadedBufferData As Byte() = hwr.GetPreloadedEntityBody() end if
what more do i have to do so that i can get return value form GetPreloadedEntityBody() function.
my table field allows null values. but my code below does not work unless a value is assigned to my variable even though the glable variable is initialised to 0; tried the DBNull.Value - still, it gives me error as the table in question is linked and expecting a value.
Inside a function I need to check to see if a variable value is null, how to do this? I implemented the code but its not returning the value I thought it would return.If it's null I want to set the value of the variable, else I want to query the value from a table

I have designed a asp.net page which create graphs. I have written a class file (which contain a function to render the graph,a function for entering data named insertdata(string[] s,double[] d)) in App_code folder. I pass the value into the insertdata during page load_event. I saw a feature of googlechart.when you pass the value in url address bar it will create a graph according to that passed value. how can i pass the value into the insertdata() function through url address?
I have Listview which databound to Dataset with about 20 items per row. I have a function which executes on each ItemTemplate appearance and gets about 10 params from Eval("something"). So basically one function builds and image from 10 parameters.Instead of passing 10 Eval("something") to the function is it possible to pass it whole row and how to use this row inside of function because it is not simple DataRow or ListView row which i can access as array of items (datacolumns).

I am working on ASP.NET 3.5, c#, visual studio 2010. I have made a master file and a default page that uses this master file. I have placed a couple asp:contentplaceholders in the master and corresponding code in the page that uses this master. I have also inserted JavaScript like this in the content page (and not the master):
On running the website I get the following runtime error in visual studio: Microsoft JScript runtime error: 'this.node' is null or not an object and it point to some function inside the JavaScript like this.node.onload=function(){..............//I am not a java guy so do not know much about this Where am I going wrong? Why does the site compile correctly but throw this runtime error? I also tried inserting this java code inside the master file in the <head>, but same error.
I have never passed along variables to a function before. I have a function here that should return true or false.
My question is, how I do this in a realtime example. How do you pass along the 4 string variables to the function and see if cbValid is true or false ?

Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window. All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.

In a GridView, I am using ItemTemplate section for multiple editing. I am using ClientValidationFunction property of MaskedEditExtender to run a client side function. Let's call it MyClientFunction . How can I pass an ID of a control found in the gridview row to my MyClientFunction?
I know how to do it via RowDataBound as follows: Is there a way to wire it up in ClientValidationFunction property?
Dim NewDte As TextBox Dim PrvDte As Label NewDte = CType(e.Row.FindControl("EditReadingDate"), TextBox) PrvDte = CType(e.Row.FindControl("lblEditLstRdgDte"), Label) NewDte.Attributes.Add("onkeyup", "javascript:ChkDteMultiple('" & PrvDte.ClientID & "')")
