Asp.net - Debugging Code In Aspx Files?
Feb 15, 2011
I am converting an old asp project to a new .NET project. Now, all vb code are inside aspx files, and we are on the process of moving all vb script from aspx files to .vb files. My problem is, I can't debug the vb script inside most of the aspx files. All my friends don't have this problem. I think the problem is with vb text editor.I am using Visual Studio 2008. Is there anyway, I can make visual studio understand that aspx files have vb script inside them.

I've had the same problem a couple of times with different ASPX pages after renaming them and I am surprised that I can't find someone else with the same problem on stackoverflow.When I run my ASP.NET C# project, the debugger gives me a message like this one.
Error 5 The name 'txtTitle' does not exist in the current context
It seems that the aspx and aspx.cs files at no longer bound. The only fix I have found for this is to recreate the page and copy/paste my code. how to fix this without recreating the whole thing?

I have an VB ASP.NET (.aspx) file that has deeply nested logic and I'm getting lots of build errors like "If must end with a matching End If" and "Do must end with a matching Loop". How do I begin to debug this beast to at least get it to build?

Here's the code:

The problem is that when I actually download the file from my source, then upload it to my destination. The only thing in the file is a piece of text that says "System.IO.Streamreader" What am I doing wrong here?

my aspx web app needs to allow clients to load files (excel files) to some place in the server, to be able to open and read content via OLEDB
immediataly after upload. Are there any "best practices" or suggestions about location, naming and security of temporary files folders?

When I am editing VB code inside a .aspx file in Visual Studio 2010, my code is automatically indented in a bizarre way. I have searched through the options and can't find anything that fixes this. [I thought unchecking Pretty listing (reformatting) of code in Text Editor -> Basic -> VB Specific would for sure do the trick but it didn't]Example -- here is the beginning of a .aspx page:
<%@ Page EnableSessionState="True" Language="VB" Strict="true" %>
<script language="VB" runat="Server">
Dim foo As String
If I go to the end of the "Dim foo" line and hit it will indent. If I fix the indentation, the next line will do the same thing.

I installed VS2008 ona newVista Ultimate 64 Bit machine. Works great. But if I try to change some VB2008 code while debugging, the system says, "Changes to 64 Bit applications are not allowed". Why is this? And will programming on a 64Bit machine always be hampered like this

Something like this:
Namespace Test_NS
Partial Class Test_WebSite
Inherits System.Web.UI.Page
End Class
End Namespace
Or should I leave it alone and only keep the classes in my App_Code under a Namespace?

I have intellisense when i type this:<p><%= boolean.falsestring %></p>
I don't have intellisense when i typ this:<p class="<%= boolean.falsestring %>"></p>
To further clarify (see line below), the first <%=%> doesn't show me intellisense popup, the second however does, why is that? <p class="<%= boolean.falsestring %>"><%= Boolean.FalseString%></p>

On my last machine I had created a way to see a GUID variable while debugging by hovering over it. I don't remember what it was (a visualizer?). I have a new 64 bit machine with vs2008 - is there anyway to mouseover a guid value and have it appear? What makes guid's so special that their value doesn't show like most variables?

When I end my app by pressing the stop button in visual studio, is there a way for that event to trigger some exit code? I'd rather do that than include a visually distracting quit button.
Better still would be to program some kind of key sequence, eg control + q to trigger some quit code so my app can exit cleanly. Is this possible? I wouldn't know how to program a key shortcut but it might be handy.

Prior to VS 2010 I was able to debug VB6 client code from the .Net IDE by setting "Start External Program" to vb6.exe (full path), or attaching to the running vb6 executable via "Tools->Attach to Process" and have execution stop at the required breakpoints in my .Net code.
Now with VS 2010 I seem to be only able to accomplish the same by setting the target framework to 4.
Is this a bug in VS 2010, or is there a switch/option that controls this?

I can't find a way to pass a simple variable from my code behind file to the .aspx page.
In code behind I have:
Dim test As String = "test"
and in my aspx page I try: <%=test %>
that gives me the following error: Error 2 'test' is not declared. It may be inaccessible due to its protection level

I have created a class containing a few string extensions, as follows:
Imports Microsoft.VisualBasic
Namespace Extensions
<HideModuleName()> _
Public Module Extensions
[code]....
just in case it's relevant to this, I'm using .Net Framework 2.0.Would I need to register something within the aspx page in order to use extensions? If not, is there another way to enable them?

I have some VB6 code that instantiates a class which handles events that are being raised from a VB.NET component. The VB6 is pretty straightforward:private m_eventHandler as new Collection
public sub InitSomething()
dim handler as EventHandler
set handler = new EventHandler
m_eventHandler.Add handler
m_engine.Start
[Code]...
My problem is that when I debug the VB6 program, the first time InitSomething gets called, the event will not be handled (the VB6 event handler is never entered). Subsequent calls to InitSomething does work.
Everything works as I would have expected when I run the program outside the debugger. At this point, I'm not even sure if this is something I should be worried about.It may or may not be relevant but the VB.NET was converted from a VB6 using the Visual Studio code conversion tool (and subsequently manually cleaned up).

On a .aspx page, what is the best way to link a server control's property to a property of the page class (its code-behind)? The only way that I have read about is to use databinding:
<asp:TextBox ID="txt" runat="server" Text='<%# Me.SomePropOfMine %>' />
and then call Me.txt.DataBind() or Me.Databind() from the codebehind. Is there any way of establishing this relationship on the .aspx page alone, or simplifying the process if you have many controls to bind (without binding the entire page)?

i wrote a piece of code to write some data to a card reader, and read back from that device, filling a form with the data (after reformat).When I step through the code while debugging (using F5, F8 for stepping forward) the form is filled correctly.However, when I run the code (Ctrl-F5), the program seems to hang for about 5 sec and then throws an exception: 'Length should be >0' When looking further during debug - it seems that the program calls 2x the Sub Frm_Read_Display().

I have two aspx pages. I need to send a textbox(record_id) value as a parameter from page1.aspx to page2.aspx to be utilized within a SqlCommand query in the VB code behind page. I would like to pass this parameter using the session. Page1 is a gridview which displays records from a sql datasource and on the edit button click the user is redirected to page2 which populates several textboxes and drop down lists and allows the user to edit the record.
page1.aspx:
<div id="header">
<h1>Page1</h1>

There has to be a setting for this somewhere, but for the life of me I can't find it. When I "Start Debugging (F5)", if there is an issue with my code, I get a "Build Failed" notification, in the lower left of my screen. I would like to be directed to the location of the failure. So far I have been lucky and have been able to find the offending code but this is getting scary .

If Page1.aspx opens Page2.aspx in a window, how can I have Page1.aspx refresh once Page2.aspx is closed?I have a page with data on it and I have a LinkButton set up so the user can edit that data. The LinkButton launches another windowed page with some text fields and a "Save" & "Cancel" button. Once one of those clicks I execute a save and close the window OR just disregard the information and close the window. I was hoping to have the initial window with the data on it refresh once the 2nd window is closed.
