It is really very hard to understand why,
Globals.SendMail(user.Email, "Verify your " + Globals.APPNAME + " membership.", eml);
fails in your application. But in any case, we are not able to help you out by just reading the code out. We need more information, such as the email address or the service being used.
In case of the email, what is the reason for it not being sent, or any error message? Did you try using the following code? In your own code, what happens is that the code creates a new task in the pool, and then returns a task object for that. However, as soon as the last line gets hit your reference is lost and (maybe, maybe...) your code is unable to proceed to send an email. That is why, I am going to write the code that actually waits for a task to finish.
Task task = Task.Run(() =>
{
string eml = System.IO.File.ReadAllText(Server.MapPath("~/app_data/verifymail.txt"));
eml = eml.Replace("[username]", user.Name);
eml = eml.Replace("[appname]", Globals.APPNAME);
eml = eml.Replace("[vericode]", user.ResetCode);
eml = eml.Replace("[appurl]", Globals.APPURL);
eml = eml.Replace("[userid]", user.ID.ToString());
Globals.SendMail(user.Email, "Verify your " + Globals.APPNAME + " membership.", eml);
});
task.Wait();

Hello Afzaal Ahmad Zeeshan, first of all thank you for take the time&effort! I have implant your code and no error message,
I did not have received any 'error email' it just not send. I will show you a part of my web.config file, I use mailjet.com;

Can you look in the control panel of MailJet services? I think the problem is somewhere on that side. Check if the email request received or not.

Hi Afzaal Ahmad Zeeshan Thanks for your respond!, I have looked up on the control panel in Mailjet services, There were no 'email requests' exept for changing the password (That work like a charm)I have try with diferent emails, but no positive results. I do not know anymore what to do,
|
|
|
|
|
Then you need to debug why the email requests were not being sent at all. You will need to debug it, set breakpoints and see why code doesn't execute the statement.

Thank you Afzaal Ahmad Zeeshan, I need to learn how to set breakpoints (working on visual studio 2015)and then see why the code is execute the statement. It is realy hard to understand why it is not working, as i mentioned in previous post's the 'resett/forgottenpass is working well......

Hello. I have this backgroundTask whose output type is Windows Runtime Component.
I have absolutely no idea how to use this backgoundTask in my winform application. Basically this backgroundTask gets geolocation and retrieves long/lat. Here is the skeleton for reference
public sealed class LocationBackgroundTask : IBackgroundTask
{
async void IBackgroundTask.Run(IBackgroundTaskInstance taskInstance)
{
BackgroundTaskDeferral deferral = taskInstance.GetDeferral();
try
{
}
catch(Exception ex) { }
finally
{
deferral.Complete();
}
}
}
Again, I have no idea how do I use this runtime component from my winform application (a button will invoke this). This code is in one project and my winform application is second project.
Thanks for any input

Where did you find that code, or API? That requires you to involve Windows Runtime with Windows Forms? Although I am not saying that WinRT and .NET do not go well, they do and that is the beauty of C# itself.
But, what I wanted to know was, why would you need to do that, when there are many easy cases? Secondly, if an API does expose these types, then it would also expose some wrapper types, too. Are you a bit confused about the term, "component"?
Finally, as I can see, your IBackgroundTask.Run function has a void return type — void can be captured in .NET itself, no need for any Windows Runtime component. That looks like the default Windows Runtime background task interface, you should read a bit more about it here, Background Tasks in Windows Store Apps -- Visual Studio Magazine, it shows a good example of handling these background tasks. That will help you understand how it works.
Anyways, please do read this by Scott Hanselman as well, How to call WinRT APIs in Windows 8 from C# Desktop Applications - WinRT Diagram - Scott Hanselman

It is a sample I downloaded somewhere on the web.

One of them would be, to not expose the native typing in either of the cases. Use the types that can be used in both the runtimes.
Since you are writing a background task handler, there is no need to use Windows Runtime background task handler, you can do that in Windows Forms itself using .NET framework's Task API. Which is much more simpler and easier to use.
Task Class (System.Threading.Tasks)
Secondly, if you really do require to have a WinRT component, then make sure it exposes the type that .NET can consume natively; such as returning the string values, integer results etc. Since you only provide an interface implementation, it is very hard to tell what you want to do with that code.

When my form design interface when editing files close and reopen frmMain.Designer.cs not see the look of the form, press Rebuil ..., press F5 or click Clear Solution no errors, press F5 to run normally, view form, but not the interface design in the form editor mode, in drafting VS screen and press select view designer frmMain.cs it his fault output stream to the attached word file, this case you can go back to the most recent edits or a way to view the form interface design?

Instead of writing a stream-of-consciousness and posting it as a question, please try considering us as normal humans, who can't see your screen, access your HDD, or read your mind.
Try again, and use proper sentences and better explanations of exactly what you are doing, what you are seeing, and why it isn't what you wanted. The less you write, the more likely we are to misunderstand you, or not understand at all.
And if you want to show us an error message, copy and paste it into the post - never try to distribute anything via a DOC or DOCX file as these have been known to contain viruses or malicious macros, and it's very unlikely that anyone will download them.

Is this at all possible?
Consider these simplified classes:
static class Class1
{
internal static int GetValue(int First, int Second)
{
return First + Second;
}
}
static class Class2
{
internal static String GetSignatureFromMethod<TResult>(Func<TResult> Method)
{
String SomeCalculatedValue = A calculation depending on the existence of Val1, Val2 + the result of Method();
return SomeCalculatedValue;
}
}
class Program
{
static void Main(string[] args)
{
int Val1 = 3;
int Val2 = 4;
Func<int> Function = () => Class1.GetValue(Val1, Val2);
Console.WriteLine(Class2.GetSignatureFromMethod(Function));
Console.ReadKey();
}
}
I haven't found a way of doing this generically.
My searches indicate that it's not possible to do using reflection, at least not without deep knowledge of IL code.
|
|
|
|

No, not like that. By the time your Main gets to Class2.GetSignatureFromMethod the parameter values are no longer on the stack. They just don't exist anymore.
You've picked a very difficult problem that cannot be done without that knowledge of IL. The thing is that you have to grab the parameter values while the code is still in the method that you called. If you call ANY other method while the method your interrogating is running the stack gets deeper and you have to walk the stack to go get the correct parameter values. How far down the stack do you have to go? This is entirely dependent on your interrogation code.
|
|
|
|
|
Thanks for confirming. 
Seems I'm stuck with a parameter array and/or a whole load of overloads for the GetSignatureFromMethod.
Or I have to get the architecture changed.

Not saying it's best for your situation, but you may want to consider using "dynamic" objects, parameter object arrays (like WriteLine()), and / or Name-Value collections for interfacing.

I would have preferred to avoid that kind of solution, but since I can't think of any alternatives...
|
|
|
|

If it's "all your code", than I would change all methods to have an "object sender" (and perhaps an "args-type" instance); and "reflect" on that.
Same pattern as the WPF / Windows Forms (ui) event model.

With a compiled delegate, it's going to be almost impossible.
In your specific example, the Function.Target property will return an instance of an anonymous type, with a field for each captured variable, and one for the delegate:
Function.Target == new
{
Val1 = 3,
Val2 = 4,
Function = Func<int>
}
However, without reading the IL of Function.Method, you have no way of knowing which field corresponds to which argument.
Things get even more interesting if the anonymous closure type is shared between multiple closures, or you're not using a closure at all.
You might be able to extract the information if you use an Expression<Func<T>>[^] instead of a Func<T>. In simple cases, the following seems to work:
Expression<Func<int>> expr = () => Class1.GetValue(Val1, Val2);
var body = (MethodCallExpression)expr.Body;
var parameters = body.Method.GetParameters();
for (int index = 0; index < body.Arguments.Count; index++)
{
var arg = (MemberExpression)body.Arguments[index];
var instance = arg.Expression == null ? null : ((ConstantExpression)arg.Expression).Value;
var field = (FieldInfo)arg.Member;
object value = field.GetValue(instance);
Console.WriteLine("{0} = {1}", parameters[index].Name, value);
}
However, this code is rather fragile, and likely to break if you pass in any "interesting" expressions.

I've meant to respond to this post for a while as it deserves a proper answer, but I had to leave for Germany to go to a funeral so I haven't really had the time until now.
But the very long answer that I thought out boiled down to a very short one in the end.
I'm going to explore the Expression methodology, more for educational purposes than anything else, but since it indeed seems to be quite fragile I'm going for a different architecture for now.
Thanks for the insight!

Hello,
I think I am level basic at programming, but I'm not lazy to search on internet when I have a problem.
Although I need help because I searched on the internet for hours and when I found something what was looking good, it didn't help me.
And because of that I'm asking you guys if you would help me please. In code's comments are my problems. Thank you for replies.
