This error usually happens when your web app runs on a web farm but the machineKey isn't the same across all servers. Is this an issue in production? Check out this article on MSDN for more info.

Hi all. I am using Microsoft Visual Web Developer Express 2010. I am finding working with the controls on the form very annoying, as it is hard to place and rearrange the various components e.g. labels, textboxes, unlike in Microsoft Visual C# Express 2008 (where you can drag and drop and adjust a component anywhere on the screen)
I have tried using tables, and though they work, the components are hard to get positioned the way you want (see the link below with labels). Is there an easier way of laying out the controls? Thanks

WebSite or Web application?
If you name the controls you can position them by changing the values in css

I think you need to change your approach, or way of thinking for Visual Web Developer Express.
It's not about using the Preview Mode to design your web forms like on Visual C# Express.
[Visual C# Express]
Programers use the design mode to quickly design or layout windows forms, for the x/y position of the objects always start at 0/0 or the top/left of the form. In a windows for, there is usually just one container to keep track of, so it's easy to drag and drop controls on to the form.
[Visual Web Designer]
Microsoft tried to do the same thing in this program, but it really doesn't work out, because a web form can be made up of hundreds of containers to store objects.
I've been doing this for over 13 years now, And I can advise you to not use the preview mode to design forms, because the preview mode uses Internet Explorer to render the objects, and they will not look the same on all browsers.
If you use the preview mode to adjust a container or object, it will inject bogus HTML and CSS into the code, in which fixing it may not be an industry standard thing. It will confuse you more, trust me.
I use the preview mode to just select objects, so I can use the property panel F4 to adjust the object. That's it.
[Advice]
Your really better of just typing straight into the code window, using HTML or HTML 5 if your program supports it. A web page is not about asp.net, it's about HTML and CSS Styles, so you should hone your skills there first.
Technology like PHP, ASP.Net is 2nd, after HTML and CSS.
Learn how to design web pages first. Start with a master page for your template, and then web forms that inject HTML into the Master Page content containers.
You can download my demo project here, as a start or to simply view how to construct a proper asp.net website.
HKB Project[^]
When you start designing forms for submission, then you replace that HTML Textbox tab with the asp.net textbox object <asp:textbox>, so you can access it in Code Behind. The same with the submit button and so forth.
[Conclusion]
I hand type everything on the keyboard, I create the containers with div tags and tables to construct my layout, and then I populate each container until finished. I don't use the asp.net object anymore, because most of them are difficult to manage, and time consuming to create and maintain.
I can do this in straight HTML, or pure code behind, in almost any technology, because I have a strong knowledge of HTML and CSS.

this is the code:
event_log_sql_command.Parameters.Add("param_mobile_manufacturer", MySqlDbType.VarChar).Value = HttpContext.Current.Request.Browser.MobileDeviceManufacturer;
event_log_sql_command.Parameters.Add("param_mobile_model", MySqlDbType.VarChar).Value = HttpContext.Current.Request.Browser.MobileDeviceModel;

What is the Congiguration manager class in the code and how to you set it in the Project or IDE?
How do I set AppSettings in an ASPX project's Configuration manager?
This is an ASPX/CS Project with Visual Studio 2010. It is a Configuration Manager question.
I am successfully debugging (sort of) some code that is being used already on a server. But there is a piece of code that plays with the URL in the live version that should not be used in the debug/localhost version.
<pre lang="c#"> protected void Page_Load(object sender, EventArgs e)
{
if (ConfigurationManager.AppSettings["IsTesting"] == "false" && Request.Url.ToString().Contains("http:"))
{
Response.Redirect(Request.Url.ToString().Replace("http:", "https:"));
}
LoadMasterTemplate();
}</pre>
This piece of code lands on the "Response.Redirect...." line when it should not because the "IsTesting" app setting should be set to true in the ConfigurationManager . How do I set that?
|
|
|
|
|
There must be one configuration file in your project. named App.Config.
you can see one section for AppSettings. Check if below section present in your configuration file.
<appSettings>
<add key="IsTesting" value="true" />
</appSettings>
So you need to change value attribute value in the configuration file.
Hope this works for you.
Thanks

FYI:
Looks like the program is forced to run in SSL mode, unless testing, then the Page Load function forces the program to run in non SSL mode, because SSL request don't run in the web dev.
So you would want to change the value to true in your .config file., and change it back to false when done.

How can i access a control or function from asp page in Global.asax?
for example call a function from Default.aspx in Global.asax
|
|
|
|
|
Why would you want to do such thing? Global.asax has it's own responsibilities and triggers.

That's not the right place for some utility method.
Create and place a new class in App_Code folder. Expose the method and use it in your pages where needed. Global.asax is not for such things. Please read about it.

Hi All,
I have following linq to entities query, it looks good for compilation but giving me the following error when I run the code. And I want to get a very complex object, which is having some list of derived objects from EDM models. The lists in the below class are not directly from EDM models but they are derived classes from EDM to add more complexity to my problem. Here is the error message. Please help me in resolving this query. I have to get all the data that I want in one linq query thats what my lead is asking me for earlier I had one query for each component and I was adding them. But lead wants it in one query. Please help me in any ways link or code snippet or any suggestion please.
LINQ to Entities does not recognize the method 'System.Collections.Generic.List`1[LNI.WSAW.External.StayAtWork.EmployerAddress] ToList[EmployerAddress](System.Collections.Generic.IEnumerable`1[LNI.WSAW.External.StayAtWork.EmployerAddress])' method, and this method cannot be translated into a store expression.
And Here is the code:

Hi Abdul,
In your Linq to SQL Query, Can you remove all references to ToList() and in the datacontract, change all List types to IEnumerable type. It should work. You are not supposed to use ToList() or First() in linq to SQL query. FirstOrDefault() is preferred instead of First().
Thanks,
Swamy

Hi,
when I put the IEnumerable it is giving me the following error.
Unable to cast the type 'System.Linq.IQueryable`1' to type 'System.Collections.Generic.IEnumerable`1'. LINQ to Entities only supports casting Entity Data Model primitive types.
when I put the IQueryable it is giving me the following error.
The cast to value type 'Boolean' failed because the materialized value is null. Either the result type's generic parameter or the query must use a nullable type.
When I used in the query value assignment conditions
t.checkvalue = iif(t.checkvalue<>nothing,t.checkvalue,false)
Still it is giving me problem that it is not able to understand the query. Please help me. I am really in need. Any kind of help, link or code snippet anything.
Thanks & Regards,

Hi Abdul,
This is what I tried and worked for me. I hope this is the same you too are looking for. I tried this in .Net framework 4.0 using Linq to Entities.
public class DbTestClass
{
public void Test()
{
using (var context = new Model.ParadiseEntities())
{
var items = from s in context.Survey3D.Take(5)
select new Testing
{
TestId = s.Id,
Items = from v in context.Volumes where v.Survey3D_Id == s.Id select v,
Items1 = from v in context.Volumes where v.Survey3D_Id == s.Id select v,
Items2 = from v in context.Volumes where v.Survey3D_Id == s.Id select v,
Items3 = from v in context.Volumes where v.Survey3D_Id == s.Id select v,
Item = context.Volumes.Where(a => a.Survey3D_Id == s.Id).FirstOrDefault()
};
var list = items.ToList();
}
}
}
[DataContract]
public class Testing
{
[DataMember]
public Guid TestId { get; set; }
[DataMember]
public IEnumerable<Volume> Items { set; get; }
[DataMember]
public IEnumerable<Volume> Items1 { set; get; }
[DataMember]
public IEnumerable<Volume> Items2 { set; get; }
[DataMember]
public IEnumerable<Volume> Items3 { set; get; }
[DataMember]
public Volume Item { get;set; }
}
If possible please send your linq query and data contract to , I will try to look into it.
Thanks,
Swamy
