I develop a Rest Service by using ServiceStack.
My model contains a DateTime property and the problem start with it.If a client post/get wrong formatted date value as string , ServiceStack fires an exception "String was not recognized as a valid DateTime."
Stack Trace:

I know its an error and I know it must be catches but I want to implement it with my error codes and error descriptions(human friendly).
Any advice could be very helpful about how to catch an exception before its written to response itself on (DebeugMode=true) or the service fires an exception to client.
Thnx
Add your Custom Request Binder (or more advanced option is to implement IRequiresRequestStream on your DTOs) to by-pass ServiceStack's deserialization with your own.
More information about this is contained in ServiceStack's wiki documentation

How can I disable location while single UI test in xamarin forms (I am using Android 8.1 simulator)? In one test case I want cancel location permission, and in other simulate that the GPS can not find user location.
I thought about backdors, but I did not found nothing useful or up to date on msdn and stack (some links pasted bellow).
I have tried something like this (and much more similar 'mutations'):
Droid.MainActivity:
[Export("GpsBackdoor")]
public void GpsBackdoor()
{
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.PutExtra("enabled", Java.Lang.Boolean.False);
SendBroadcast(intent);
}
UITests.Test:
[Test]
public void SetCurrentUserLocation_WhenGPSisOff_ShouldShowAlert()
{
app.WaitForElement(x => x.Text("Nearest stops"));
app.Invoke("GpsBackdoor");
app.Tap(x => x.Text("Nearest stops"));
var result = app.WaitForElement("Could not obtain position");
}
After running test I am getting message:
System.Exception : Error while performing Invoke("GpsBackdoor", null)
----> System.Net.Http.HttpRequestException : An error occurred while sending
the request.

This is critical, as it makes our customizations unusable ! (and also prevents us from importing customizations automatically, as this process uses Web API)
Note that the same solution has been imported in another organization the same way without issue ...
The import of the solution through the UI still works, but that completely defeats the point of our automation pipeline ...
Has anyone encountered this issue ? Where should I look ?
(note : I have also posted this question here : https://community.dynamics.com/crm/f/117/t/206996 )
It seems your OData is not enabled or not supported. Please check via

I have a hard time trying to fix the problem. I follow everything and even redo it just to make sure I got it right. I don't think I miss any steps. But there is something wrong. If I run the whole sample code, everything works fine.
Any help is appreciated.
Thanks,

EDIT:
It was really frustrating for a simple thing that lead to an error like this.
#mmeasor, I just saw that error as well. It cannot connect to database. So that lead me to check the connection.
What happen was that at first I used this connection string:
So EntityFramework created a database file ContosoUniversity1.mdf in here like C:\Users\Office\ContosoUniversity1.mdf. But then I want it to create another one and use that instead and this time I want it to be in the program App_Data\ folder instead.
So I modified the web.config file to:
I thought if I do that, EF will create a new database for me in the \App_Data\ folder and link to that instead of the old on in C:\Users\Office.
I was so wrong! that was when I start getting the error posted above. And I cannot find what causes the problem.
With the second web.config, I tried to copy the database file to the App_Data folder, but that still doesn't work.
Now I use the first connection string and it works fine.
So now the question is: How to make the program links to database file in the \App_Data\ folder instead?
Thanks,
Pheap
I had the same problem in trying to change location of Conosto University tutorial database from User folder to App_Data folder. John Locke keyed me into the idea that it may have something to do with having to change the name of the database.
Change name slightly of database named in the web.config file (This works inconsistently, but does work consistently inconsistently. If I had to test this again...and I'm sure I will at some point...I would stay away from reusing names - i.e. don't toggle back and forth between two name preferences (e.g. database1 and database2 back to database1 - I would use completely novel names e.g. databse7...database8...database9 - get name away from previously used names)
I also had luck, once a database was created with the name I didn't want, changing the database name to what I wanted it to be and matching that name in web.config (i.e. I was able to create a "database3.mdf" file successfully and then changed it in the OS to what I wanted - "database1.mdf" and matched the web.config file to database1 and it connected up on the first try)
I had this problem for days ("An exception of type 'System.Data.DataException' occurred in EntityFramework.dll but was not handled in user code") and I tried everything since changing the connection string to many different methods I saw on Internet questions and answers,
My solution?...
Created a new proyect with another name, and it saved me.
Here EmployeeDetail is a table name and Employee is a model name. And
ID,Branch, Salary and UID are table fields:
public ActionResult Index()
{
List<EmployeeDetail> employees = context.EmployeeDetails.ToList();
List<Employee> emp = new List<Employee>();
foreach(EmployeeDetail item in employees)
{
emp.Add(new Employee
{
ID=Convert.ToInt32(item.ID),
Branch=item.Branch,`enter code here`
Salary=Conve`enter code here`rt.ToInt32(item.Salary),
UID = Convert.ToInt32(item.ID),
});
}
return View(emp);
}
view page code
<div style="font-family:Arial">
<h2>Index</h2>
<ul>
#foreach (var emp in Model)
{
<li>
#Html.ActionLink(emp.Branch, "Details", new { id = emp.ID });
</li>
}
</ul>
</div>
I'm seeing a strange behavior in my MVC3 application. I have an Action that is called by Ajax, and receives a Post with HTML text.
I want to allow the entry of HTML, so I set the ValidateInput(false) attribute. I also have a global OutputCache filter with this parameters: (NoStore = true, Duration = 0, VaryByParam = "*" )
The code looks like this:
[HttpPost]
[ValidateInput(false)]
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*" )]
public ActionResult Edit(SomeModel someModel)
{
saveModel(someModel);
return new AjaxEditSuccessResult();
}
When I send a post to that method, it is executed and the model is saved, but the response I get is the standard "A potentially dangerous Request.Form value was detected from the client" error message, with this stacktrace:
[HttpRequestValidationException (0x80004005): A potentially dangerous Request.Form value was detected from the client (text="<p class="MsoNormal"...").]

Do you know if I can indicate in any way to the OutputCache attribute that it needs to respect the ValidateInput attribute?
There are two places in the flow where validation is invoked:
on controller method invokation
when rendered result is stored in the cache.
You have fixed first problem with ValidateInputAttribute(false), but looks like cache module is ignoring the NoStore directive and still tries to construct the cache key and before doing that it validates the arguments, to get rid of that specify: Location = System.Web.UI.OutputCacheLocation.None, so that cache module will not even try to do anything. Replace your OutputCache[...] with something like this:
[OutputCache(NoStore = true, Location = System.Web.UI.OutputCacheLocation.None)]
I have a web application on .NET4 and MVC3 (razor) .
I want to handle my application errors in Global.asax. I have created application_error function.
I have noticed and found some errors.
one of them returns this string in Application_Error when I am trying to add break point on line Response.Clear(); and that error is generic.
how can I find which codes or part of my codes makes it?
my code:
protected void Application_Error()
{
var exception = Server.GetLastError();
var httpException = exception as HttpException;
Response.Clear();
Server.ClearError();
}
error on httpException:
{System.Web.HttpException (0x80004005): File does not exist.

i found the solution
string errorLocation = Request.Path;
this syntax in Application_Error() tel you where is the problem :)
Just to state my experience with this exception, in my case the reason was that there was no webpage specified as the start page for the site.
