Strange "ambiguous in namespace" complier error disappears with rebuild

Hi all.
I am using VS 2005 and VB.NET.
Lately as my Web Application is getting larger, I have been getting strange
compiler messages like the following:
--
Compiler Error Message: BC30560: 'controls_user_createquicksearchbar_ascx
'
is ambiguous in the namespace 'ASP'.
Source Error:
Line 9:
Line 10: <asp:Content ID="Content1" ContentPlaceHolderID="Content1"
Runat="Server">
Line 11: <uc1:CreateQuickSearchBar ID="CreateQuickSearchBar1"
runat="server" />
Line 12:
Line 13: <uc2:PCSavedSearches ID="PCSavedSearches1" runat="server" />
--
This typically occurs after I have made a change that is in a code-behind
page in which the offending User Control is placed and I do a complete
rebuild and then test.
After the error occurs without making any other changes to the code, I
simply do another full rebuild from within VS and the error goes away and
does not re-occur.
Has anyone experienced this? Is there a fix for it? It is becoming both
annoying and time-consuming.

I have exactly the same problem. I have googled, asked here but no answers
/ solutions. Get out of the car and get back in. The only thing I can
think of is that depending on where my right hand is (on mouse or keyboard)
I will use F5 or click start debugging toolbar button. I always thought
that was the same but it seems that if I use only one of those combinations
I don't get the problem.

Strang behaviour of multiselection Listbox

Hello,

i´d like to get access to the selected items of my listbox...

I did this in a loop, but I get only acces to the first selected item of the Listbox.

Has anyone solved the same problem? I really need help. Thx in advance.

Code (VB.net):

dim el as listitemfor each el in mylistbox.Items if el.selected then 'do something end ifnext

Give this a try...

 iCnt = 0 Dim li As ListItem For Each li In myListBox.Items If li.Selected Then iCnt += 1 Next If iCnt <> 0 Then Dim i As Integer iCnt = myListBox.Items.Count For i = 0 To iCnt - 1 If myListBox.Items(i).Selected Then 'Do Something End If Next

 End If

 Zath

Still the same problem
I´m sad...

But thank you for the try...

That shouldn't be.

Do you have this line in there?

If myListBox.Items(i).Selected Then

Zath

Yes...

No matter what I do, the first selected item returns true for .selected

the next ones return false...

ListBoxes (and CheckBoxLists) expose a new property called "GetSelectedIndices()"

So you can say

Dim LI As ListItem
For Each idx As Int32 in mylistbox.GetSelectedIndices()
LI = mylistbox.Items(idx)
'Do what you need to do with this selected list item
Next

*If* that doesn't work for you, and there is absolutely no reason why this code or the code you posted shouldn't... then you have other issues, like for instance, re-binding the list on every page load (which would "reset" the listboxbefore your event handler got a hold of the control)

I´m working on 1.1 so that the above function is not available for me...

But I will check the second issue. Thanks for the hint...

That did the trick... Sorry for the wasting of your time...

Did a wrong binding on PostBacks so I killed all of the selections except of one in the listbox...

*smashing head against the next wall*

i can't speak for the others replying on this topic... but you didn't/aren't wasting my time... glad to help out...

the whole binding cylce is a huge "gotcha" in .NET, we've all had our battles with it

(this is where you tell them "but it sure is great thatEasyListBox doesn't have that problem" )

Strange "expected ;" error

I am getting an error and I can't seem to figure out why. The error is on line 32.

Compiler Error Message: CS1002: ; expected

Line 30: strScriptName=Request.ServerVariables("SCRIPT_NAME");
Line 31: strFolder="/buildlauncher/";
Line 32: If (strScriptName.IndexOf(strFolder)=-1)
Line 33: {
Line 34: strbuildlauncher="class='selected'";

The language I am using is C# and I don't seem to understand what a ; would be doing in an if statement. What I am trying to do is determine if the folder specified in the strFolder variable is in the server variable SCRIPT_NAME.There are some syntax problems here:

If (strScriptName.IndexOf(strFolder)=-1)

should probably be

if(strScriptName.IndexOf(strFolder) == -1)

Note the case sensitivity and the equality operator.

Strange "ambiguous in namespace" complier error disappears with rebuild

Hi all.

I am using VS 2005 and VB.NET.
Lately as my Web Application is getting larger, I have been getting strange
compiler messages like the following:
--------
Compiler Error Message: BC30560: 'controls_user_createquicksearchbar_ascx'
is ambiguous in the namespace 'ASP'.

Source Error:

Line 9:
Line 10: <asp:Content ID="Content1" ContentPlaceHolderID="Content1"

Line 11: <uc1:CreateQuickSearchBar ID="CreateQuickSearchBar1"
runat="server" />
Line 12:

This typically occurs after I have made a change that is in a code-behind
page in which the offending User Control is placed and I do a complete

strange & weird problem in ASP.NET application

I am having a strange problem in my ASP.NET application. When
multiple users access the web site, the changes done by a user gets
reflected in another users session.

I have some global variables declared in a module which I use
throughout the application. Is it problem because of this? If I cant
declare a global variable in a module where else can I declare it
where it cannot be changed when multiple users are accessing the same
variable?

Please somebody help me.

-Shalinthat would be the difference betueen session variables and application
variables
you would need session variables
have a look at the pass variables value between diferent pages thread

hope it helps

eric

Strange "Object reference not set to an instance of an object" error in webform

I suddenly received an unexpected error in my project. I have been working
on this project for some time without this issue. Nothing has changed in the
form that caused the exception. A little experimentation shows that I cannot
run ANY .NET web project without getting this error:

-----------------------

ChrisVery strange indeed. It might sound obscure, but try removing the

Otherwise, I would be tempted to do the inevitable and reinstall the
