Web Forms :: Return Values On VB.NET Functions?
Oct 19, 2010
I have been reading that a value needs to be returned by a function, otherwise the following error will occur:
"Function <function name> doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used."
The cure, I have found, is to return something (i.e. "Return 0") before exiting the function. Can I pass this return value back to the routine that called the function? If so, how do I code this?
Most of the time, however, I find I'm not needing to return a value anyway, and just end up adding "0" to the ends of all my Return statements. Does anyone have any comments on this?

I am trying to write a simple string manipulation on a formula field. Left (string, N) returns junk character but if I hard code N to some numbers it returns proper string like Left(string, 10) returns good;
Left (string, 10) --> returns good stringLeft (string, Instr(string, ">")); --> returns junkX := InStr(string, ">"); Left (string, X); --> returns junkHere is my formula field:
local StringVar temp;
local StringVar temp1;
local NumberVar x;
temp := "<span style='font-size:10pt;font-weight:bold;color:red;'>testing</span>";
x := InStr (temp, ">");
temp := Left (temp, x);
if (1=1) then
temp;

I have a page that contains a few user controls which all use an id in a querystring. I want to change this so that the page can send the id to the user control and can call a function on the user control.
Also is it possible for the user control to get the id from the page or a control on the page as its parent?

I have a text box that has values separated by a comma. I am trying to remove the duplicate values for, example this text box will have values like:
John, Adam, Mike, John, Mike
I want it to return unique values like:
John, Adam, Mike
I found a VB function and converted it to C# but it's giving me errors like newArray is a variable but used as a method. Thanks

i've got a gridview and sql datasource. Its connected to a stored proc that has four optional parameters. In VS when i set up the data source, if i use the test option, and dont supply any values for the sproc, it returns all the values in the table which is what it should do. Now when i try to fill the gridview, it wont return anything at all unless i provide values for all 4 parameters.
It's not even trying to search because i had sql profiler open and nothing shows up until i provide all 4 values. any idea why it's doing this? How do i get it to actually bind even if provide less then all 4 (or none) of the values?

I have a grid view and I added edit and Save buttons to it. When I click on edit I am able to edit the data but when I click on save I amgetting the data before edit.
Please see my code below.
Eg: I have start date as 2005-10-10 12:00 AM so After I click On edit it is letting me to edit, So If I edit the start date to 2010-10-10 12:00 PM and click on the save button I am stil getting the old start date. which is 2005-10-10 12:00 AM instead of 2010-10-10 12:00 PM

Dim s_Person = From Person In db.People Join ProspectStatus In db.ProspectStatus On Person.Id Equals ProspectStatus.Prospect_ID Where (Person.Organization_ID = s_Organization_ID)Select Person.
I only want to return DISTINCT values of Person.ID. Right now, it returns the same person multiple times because there are several entries in the status table.

How to return values from Webmethod to the client in JSON format? There are two static int values that i want to return.Do I need to create new object with those 2 properties and return it?The GetStatus() method is called frequently and i don't like the idea of creating a special object each time just for json formatting...
[WebMethod]
public static int GetStatus()
{
int statusProcess,statusProcessTotal;
Status.Lock.EnterReadLock();
statusProcess=Status.Process; //Static field
statusProcessTotal=Status.ProcessTotal; //Static field
Status.Lock.ExitReadLock();
return ...
}
On client side I catch the return value in :
function OnSucceeded(result, userContext, methodName)
(PageMethods.GetStatus(OnSucceeded, OnFailed);)

I have a parent page that launches a telerik radwindow and passes it an argument.
Once the radwindow is done processeing the value, I need it to return it to the parent page, and I would like the parent page to have access to this value in my code behind page.
I have tried to pass the value to a hidden field on my page and then trigger a page refresh and my code behind watches to see if the value is working.
I can't seem to get this to work. I get the return value in the parent javascript, but i can't get it from my hidden field from the code behind.

I am working on a Tag system for a news page designed in ASP.NET. For the system I require a TagExists method to check for tags within the database. The stored procedure I have written is below.
[Code]....
I have tried switching the procedure to return 0 if the tag exists and 1 if it does not and it still returns 0 despite the exact same testing conditions. I have also returned the actual select query and it has complained of the Tag "news" (my test item) not being an int on execution showing the select itself is definitely properly formed.

MOVE_MOD is defined as a float.

Naturally this is causing some issues as my C# code needs to handle decimal values. If I try to manually change the designer code to use floats, I get the following error

I have the following in an aspx page:
<td colspan="2">

</td>
In the code behind for the aspx page, i have this (e.g. I build HTML for the checkboxes):
[code]....
Not my proudest moment, but whatever. The problem is that when this page posts back via some event on the page, I never get these tags in the Request.Form collection.
Is this simply how ASP.NET works (e.g. only server-side control post back) or am I missing something simple.

I have a page that lists products from a table based on the querystring. So if I say foo.aspx?fam=1 all the products from family 1 will be listed. How can I make my code list all the values if query string is empty? My SQL command would have to be different...can't really see how I can do this.

I have a user table with userID, userName ...the standards. I also have a "Material" table with materialID, materialName, etc.
I combine these in another table "UsersMaterial" with userID and materialID, depending on which materials the user has chosen (between 0 and 5).
Now I need a stored procedure that returns the user information + the set of materials that is mapped to the user.
But I can't see how I can return one row of user information combined with a set of the user materials? Do I join or can I return a set + one row?
