I am using VS 2008 and I have created one Web Application. Previously in that I have reference for one dll, currently I do not require it and so I want to remove it.
But after removing, it get deleted from my bin folder and as soon as I build my application it gets created again
in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.

In my current project, I have a webservice file called MyServices.asmx. This webservice I want to reference in my Default.aspx.cs file.
My Code:
MyServices newService = new MyServices();
newService.addUser(txFirstName.Text, txLastName.Text, txtEmail.Text,
txtUserName.Text, txtPassword.Text, txtBalance.Text);
But when I refer to that webservice (as shown below), I get error saying: "The type or namespace name 'MyServices' could not be found (are you missing a using directive or an assembly reference?)"
What should I do to correct this error?
Current Solution of Adding Service Reference still gives me that error.
I am facing a problem with Gridview control. I have created a Gridview1 which is having 3 button column that has been added at design time and some column can be added through the Datatable at runtime. At Design time GridView1 has 3 button column
At Runtime I do GridView1.Datasource=dt; //Now my gridview is having 7 columns i.e. 4 more columns added through datatable.
I can easily display that GridView1 on webpage but I dont want to show some column that I added through Datatable to the user.
When I try to hide that column, I get error like Index out of bound exception but when I hide button column I can able to do that easily.
I'm adding a reference to a funciones.dll file using
clr.AddReferenceToFileAndPath() because I couldnt get it to work other way with this file and it succesfully does it. The file is named funciones.dll and it's in the bin folder. But when I do
from funciones import *
I get "no module named funciones"
since the funciones.dll file it's a funciones.py file compiled, shouldnt the module name only be named funciones and no any other name? isnt the name the problem and it's another? I dont know what other info could be relevant here but if there is any let me know
Does anyone know what could be the reason I am not able to add reference to System.Web. It gives an exclamation(!) symbol in front of the dll under reference folder in VS 1020. I wand to refer to System.Web.Security.MembershipProvider class.

Error 3 The type or namespace name 'Data' does not exist in the namespace 'System' (are you missing an assembly reference?)Even although I have references to System.Core, System.Data, System.Data.Linq in the website references.

when i publish my asp.net application in Release mode i am getting .pdb files in Bin folder.
My doubt is

2. Why is .pdb needed in release mode.
3. how can i remove .pdb files in release mode.
I'm just getting started with ASP.NET. I'm looking for a reference that lists all of the standard ASP controls, with definitions for all of the properties and methods for each control. All I'm finding so far are tutorials for solving specific example scenarios.Can anyone point me to such a reference? PDF would be great, but hard-print or web-based would be OK as well.

I've following line in my code:
using Microsoft.ServiceModel.Web;
And it works fine as long as I add the namespace reference to microsoft assembly dLL System.ServiceModel.
The moment I copy the code on other machine, I need to redo everything. Is there any way so that I don't need to add this reference again & again?
I'm using an autocomplete contol of ajax toolkit. Yesterday a user found that it had stopped working (it wasn't generating the list as you type letters in the textbox). After hours of troubleshooting, I found that in web.config <httpHandlers>, this line

<httpHandlers>

Since a Web Site doesn't have a project file or a bin folder,
how will a Web Site identify of what are all the dlls to be used.
And if i am adding a third party dll to my web site, and i need to
add this web site folder to a source control, how should i include
this third party dll in the source control?
I downloaded the trial version of abcpdf, which is absolutely fantastic!
Anyway, real simple, you just need to reference the .dll and off you go...
So, I got my code working, but when I moved to production server I hit a wall.
It definitely has to do with the .dll because when I comment out the pdf sub routine, the code executes and completes all other tasks. When I uncomment, It's not working.
The trouble is, on my server I don't have the full version of VS, so I am unable to add a reference, which I presume takes care of the web.config settings? I manually dropped the .dll into the bin folder and I added the assembly line into web.config, but, as I don't have the above, I am not sure if the token key is correct.
To test this, I uploaded the working .dll file to my server, which I assumed the key is associated with, but still the same.
how to either get the correct key and/or how to reference an assembly manually? Is there something I have missed?
I have a project ("The Project") that references an external web service. I am then referencing that project in an ASP.Net web application ("The Web Application"). When I reference "The Project" in "The Web Application" the app.config is not copied over, which isn't a problem. Does "The Project" take care of know what endpoint to use? Can the web.config override the endpoint URL? I did a test and am not reference the eternal web service in "The Web Application" and everything seemed to work ok. I guess, can I create the same configuration section, that is in "The Project's" app.config and copy it over to the web.config file to override?
Update: I guess what I really need to find out is how to change the end point of a web service when generating the code from adding a "Web Reference". I tried adding a service reference to my code, but the wsdl is not getting loaded correclty or I am doing something wrong. Update 2.0: I forgot about the URL property of the proxy that is generated by the web reference.
retrieve appsettings from the app.config file stored in a DLL directory?
I have read many posts on this and it appears as though it's not possible. I've tried all configurationmanager options without success.
Of course, when my .net web app runs, it configurationmanager pulls the settings from the web.config which I understand. I would just like to have a configuration file dedicated to the dll. (like app.config).
I am new to programming and i have one project in which i want to replace the DLL files and want to place the actual code. I have all the code files. how to this?
