Winforms Webbrowser - disable warning on script errors



i am hosting the winforms webbrowser control in a wpf window (whilst i believe that the wpf context doesn't matter)
i do some programmatical loading of urls and process the document's content in the handler for DocumentComplete...
If there is an error in the documents script the control displays a warning message box
sth like
"an error occured in the script of this page..{details}..do you wish script execution of this page to continued?"
As long as the warning is displayed the code asynchronously keeps on loading new urls, but fails to handle
DocumentComplete (which isn't fired while the warning is displayed).

Can I somehow programatically disable this warning?
I already did disable the checkbox under "displaying script errors" in system-control/IE-Settings.
This only seems to affect instances of IE as an desktop browser, but not of the WF-webbrowser control.
Is there a way to supress warning messages while laoding URLS in the WF-webbrowser?

errors when calling sub from submain is ssis script task


I am trying to use this code I had in a function in a vb.net application in an ssis script task. When I try to call the ImporttoServer sub in sub main I get an error "argument not specified for parameter DBName.

Rendering ASP.NET Script References into the Html Header

One thing that I've come to appreciate in control development in ASP.NET that use JavaScript is the ability to have more control over script and script include placement than ASP.NET provides natively. Specifically in ASP.NET you can use either the ClientScriptManager or ScriptManager to embed scripts and script references into pages via code.

*.axd script references not being rendered to browser


I'm running VS2010 with .net 4.0, and am running into issues with the .net ajax script tags mysteriously not being rendered to the browser.

So far I've reduced it to a scenario where I set the DataSourceID property of a databound control.  More specifically, I've only tested it on a Gridview and a DropDownList.

This can be reproduced fairly easily on my machine by following these steps:

1. Create a new empty Web Application Project

2. Create a new Web Form

3. Add a ScriptManager inside the form

4. Add a DropDownList and a DataSource (I used an ObjectDataSource)

5. Set the DataSourceID property of the DropDownList to the ID of the DataSource.  This can be done either declaratively on the .aspx page, or in the code behind in the aspx.cs page, and both produce the same results.

6. Open the page in a browser and watch as you get a javascript error stating "Sys is not defined" and notice that the page source contains no script tags referencing *.axd scripts.

Here's my source code showing my set up:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ScriptResourceFAIL.Default" %>


Client script not running


Dear all,

in my MVC 2 application, and in the shared Master Page I wrote this little script for menu handling :

<script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script>
<script type="text/javascript"> $(document).ready(function () {   
     $('#nav li').hover(  
         function () {  
             //show its submenu  
             $('ul', this).slideDown(100);  
        function () {  
           //hide its submenu  
            $('ul', this).slideUp(100);           

The script, that shows menu items when the

2 projects - same code - one, using 2008, one using 2010 - a textbox a button and a label, using html code in the textbox

In the Page Directive:
EnableEventValidation="false" ValidateRequest="false&q

How can I be sure that my entire project is up-to-date and free of errors in VS2010?


Seems like a stupid question, but I will go to Build > Build Solution many many times and the build will succeed many many times, then I will put in a minor syntax error and the build will fail, BUT the build will not fail because of the minor syntax error; it will fail because of an unresolved type that I put in about twenty compiles ago. And then I will fix the minor syntax eror, and the compiler will still complain about the unresolved type. Here is my code:

<%@ Register TagPrefix="FTB" Namespace="FreeTextBoxControls" Assembly="FreeTextBox" %>
  <form runat="server">
  Hello World!!  

Pretty simple, really. I go to Buld > Build WebApplication1 and it runs OK. Now, if I put in a minor syntax error, such as substitute "forrrrrrrm" for "form" and then try to Build Solution, it complains not about the misspelled word, but about the FreeTextBox. And then if I correct the misspelled wird, it still complains about the FreeTextBox. Which leads me to believe that Building the Solution does not check absolutely 100% everything that needs to be checked. Is there a more thorough way of compiling a program that I need to use?

Word Automation - Multiple DCOM Errors/Behavior

Before I get started, I already know that Microsoft does not support and highly discourages server-based MS Office automation.  I've read a multitude of posts and smarmy "*wink*, here's a link" replies, so I'm looking for actual help here, not condescending reprimands.

That notwithstanding, here is my problem.  I have developed a simple method that will open a local Word document, modify some header information, and then save the document as a new file.  As expected, it works great as a console/windows app, but as soon as I went to ASP.NET, DCOM jacked my world up when accessing the app remotely from a different domain account (that has access to the ASP.NET app.  For reference, my method is shown below:


1    public static string ModifyAndSaveBuildDocument(string localFilePath, BuildDocumentType docType, string buildNumber, DateTime buildDate, string projectName)
2            {
3                try
4                {
5                    ProjectConfiguration config = (ProjectConfiguration)ConfigurationManager.GetSection("ProjectConfiguration");

Cutting Edge: Custom Script Callbacks in ASP.NET


ASP. NET client callbacks represent a neat and elegant way to execute server-side code without posting and refreshing the current page. I discussed ASP. NET callbacks in the August and December 2004 installments of Cutting Edge, considering them from the perspective of rendered pages making background callbacks to the server, sending input data to the relevant page, and receiving a response.

Cutting Edge: Implications of Script Callbacks in ASP.NET


Script callbacks in ASP. NET 2. 0 is a feature whose time has come. Script callbacks can significantly speed up an application by limiting server postbacks. They also allow you to execute small portions of server-side code without having to manage the view state for reading or writing.

Cutting Edge: Script Callbacks in ASP.NET


If you're involved in Web development you may have faced a problem that you couldn't find a good solution for-making client-to-server calls outside the current page. For example, you might want to validate the content of a textbox against data stored on the server asynchronously, without interrupting the continuity of the work or without forcing a full page refresh, which is particularly heavy for UI-rich pages.
