No my web service doesnt call another. I tested the url with Postmane and it works fine. With(localhost)

I think Postman should see my service from the view of Android Emulator. Does it tell us as well?

yes, But is there any other way to understand the problem? And will Postman tell us about the undergoing problem?

That's true but I m not sure if Postman can consume 10.0.2.2 Android specific IP address. Anyway, I'm gonna try it right now.

But the problem is that I face the "Error 400 bad request" in mobile app before I enter the service, and I think the emulator cant see the 10.0.2.2 at all. Because when I put the IP in the emulator chrome browser I face this error.:(.

This is the code I have consumed in SOAP:
[WebMethod]
public string GetListInfo_GeneralCategory()
{
string strFolderPath = "\\Areas\\Admin\\UploadedFiles\\GeneralCategories\\";
List<generalcategory> lstGeneralCategory = new List<generalcategory>();
lstGeneralCategory = mapSyncWebService.GetListInfo_GeneralCategory();
if (!string.IsNullOrEmpty(mapSyncWebService.errMessage))
{
return string.Empty;
}
if (lstGeneralCategory.Count == 0)
return string.Empty;

if (Directory.Exists(Server.MapPath(strFolderPath)))
{
string[] arrFilePaths = Directory.GetFiles(strFolderPath);
for (int i = 0; i < lstGeneralCategory.Count; i++)
{
foreach (var strFileName in arrFilePaths)
{
if (strFileName.Split('_')[0] == "imgGeneralCategory" && strFileName.Split('_')[1] == lstGeneralCategory.ElementAt(i).ImageFilePath.Split('_')[1])
lstGeneralCategory.ElementAt(i).ImageBytes = File.ReadAllBytes(Server.MapPath(strFolderPath + "\\" + strFileName)).ToString();
}
}
}
return JsonConvert.SerializeObject(lstGeneralCategory);
}

this is the URL from Mobile app: http://10.0.2.2:51036/Areas/Admin/WebServices/SyncWebService.asmx
string strRawJson = string.Empty;
string strJsonString = string.Empty;
DataTable dtValues = new DataTable
{
TableName = "dtGeneralCategory"
};
try
{
syncWebService.Url = "http://10.0.2.2:51036/Areas/Admin/WebServices/SyncWebService.asmx";
strRawJson = syncWebService.GetListInfo_GeneralCategory();
}
catch (Exception ex)
{
var alert = new Android.App.AlertDialog.Builder(this);
alert.SetMessage("خطا در برقراری ارتباط با سرور! ");
alert.SetPositiveButton("بستن", delegate { return; });
alert.Create().Show();
return false;
}
var response = JsonConvert.DeserializeObject(strRawJson);
strJsonString = response.ToString();

dtValues = (DataTable)JsonConvert.DeserializeObject(response.ToString(), (typeof(DataTable)));

But, I have tested it with another MVC application, (obviously with local host:http://localhost:51036/Areas/Admin/WebServices/SyncWebService.asmx)
it works pretty fine.

Thank you for your response. But here my application is a windows service . There is no asp.net web page. Also the json contains an image with black background with a text for traffic signs. I already could retrieve the image from json but the font is too big and the text didnt palce at the middle of the background.

yess it worked , thank you so much for your help

thank you very much, but I didnt understand what did your method does?:(
and if I was going that the method catch when I write "/employment" every where at the url then what should I do?
I want to this work when the user types www.website.com/employment

can u show me an example of it?

I have explained above about this. Finding the largest number in an array in parallel. Can u please check the code and refine it? I think it has a bit bug.

Can u help me please?

I have changed the algorithm as you said but I cant still run it. Can u please help me? Im going to represent it tomorrow. thank you

import multiprocessing as mp
from multiprocessing.pool import ThreadPool


class Max:
@staticmethod
def subset_max01(arr, n, cpucount):
largest = 0
for i in range(0, n/cpucount):
if arr[i] > largest:
largest = arr[i]
return largest

@staticmethod
def subset_max02(arr ,n ,cpucount):
largest = 0
for j in range(n/cpucount, cpucount):
if arr[j] > largest:
largest = arr[i]
return largest


if __name__ == '__main__':
cpu_count = mp.cpu_count()
print("Number of CPUs: ", cpu_count)
a = []
cpuQueue = []
num = input("Enter how many elements? ")
for i in range(int(num)):
n = input("Enter a[] array: ")
a.append(int(n))
objMax = Max()
pool = mp.Pool(processes=cpu_count)

while cpu_count >= 1:

pool = ThreadPool(processes=2)
cpuQueue.append(pool.apply_async(objMax.subset_max01, (a, num, cpu_count,)))
cpuQueue.append(pool.apply_async(objMax.subset_max02, (a, num, cpu_count,)))

cpu_count = cpu_count-1

larger = 0
for i in range(0, len(cpuQueue)):
if cpuQueue[i] > larger:
larger = cpuQueue[i]
cpuQueue.remove(cpuQueue[i])
cpuQueue.append(larger)
output = [p.get() for p in cpuQueue]
print("Maximum is: ", output)

pool.close()
pool.join()

how do I allocate a subset to a process? with which statement?

Does MVC note that if the password was not hash, then it doesnt allow the Modelstate.Isvalid being true?

But I never used any hash algorithm in my application

what do you mean?

Ok . Then how can I replace the code with something right? I want to when user clicked on a product , redirect him to relevant page. Do I create a controller? and what should I place in that controller?

so what can I do?

Yes Im sure. So can you help me? This is only an <a href ... storefront/index/3

And is it possibly from rout config?

No I am passing two parameters. what can I do?

In this application, when you going to the instructors page, you have 4 action links
Select|Edit|Details|Delete|
everything is ok until you click on the "select", when click on the select link you should see in bottom of the page courses taught by selected instructor in a table. But only you can see the table headers. and when I putted breaking point , I found that the coursID passed to the action is null but Id not.

yes ,works. but ,we have another section in the page that shows course taught by the instructors , that this when courseID passing to the controller and it has null value.

What parameter I should pass to the controller from view?(Id or Model)

So I want to ask another question; is needed CourseId we declare in our viewmodel? So what is the built in id that is auto generated in sql tables?? That's some confused.

You mean I should create 3 viewmodels containing student,course,and studentcourses?

Please help me

I putted the User.aspx web form out from the folder "User" then it worked perfect!!!! Why?
So far we had Response.redirect("User/User.aspx"); and now we have Response.Redirect("User.aspx");

Because if I use RedirectFromLoginPage,asp.net takes the user to one page that I have not any control on it,for example I placed some controls on the user page like image control. Now any user that log in the profile picture changes, and the username including welcome message changes depending on user credentials.

I checked it again, I have see that I'm not redirected at all! I stayed at login page, only the url has changed:http:
//localhost:23407/GarnetGalleryCollection/login.aspx?ReturnUrl=%2fGarnetGalleryCollection%2fUser%2fUser.aspx

Yeah, the user.aspx does not show the controls it should show. May be I m not getting to user.aspx,but I saw when redirecting that in address bar , the url has changed, but the contents has not rendered, and the empty white page has displayed to me.So , I want to ask you a question that now came to my mind, is this logic is good that we place one asp.net form like user.aspx in our applications, and after each login and after pass all security considerations , we redirect the user to this user.aspx web form? Or this will not answer for a real world application? I have read many articles, but there is some thricks that are not in articles, and result in experience. If you tell me some thrick to write this parts of apps thank you very much.

Ok , I have to read this article and I'll come back to you if I couldn't find my answer in this article.Thank you.

than you, it worked

This is my solution:
storedprocedure:
USE [D:\PROGRAM FILES\MAYSAM\CSHARP PROJECTS\TRAINING\GARNETGALLERYCOLLECTION\APP_DATA\GARNETGALLERYWEBSITE.MDF]
GO
/****** Object: StoredProcedure [dbo].[SelectUserPassExist] Script Date: 02/03/2015 17:10:38 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author: <author,,name>
-- Create date: <create date,,="">
-- Description: <description,,>
-- =============================================
ALTER PROCEDURE [dbo].[SelectUserPassExist]
@Usr nvarchar(max),
@Pass nvarchar(max),
@Results int Output
AS
BEGIN
set @Results=(select count(*)from Users where ([UserName]=@Usr and [Passcode]=@Pass))
end



and my codebehind:

protected void Button1_Click(object sender, EventArgs e)
{
int intResult;

if ((intResult >1)||(intResult<1))
<!--1--> {
lblMsg.Text = "Invalid Username or Password.";
}
else
{
{
Session["Usr"] = txtUsername.Text;
FormsAuthentication.RedirectFromLoginPage(txtUsername.Text, chkRememberMe.Checked);

}
}
}
private int CheckUserPass(string strUsr, string strPass)
{
int retVal;
string strConnectionString = ConfigurationManager.ConnectionStrings["GarnetWebsiteConnectionString"].ConnectionString;
SqlConnection con = new SqlConnection(strConnectionString);
SqlCommand com = new SqlCommand();
com.Connection = con;
com.CommandType = CommandType.StoredProcedure;
com.CommandText = "SelectUserPassExist";

com.Parameters.Add("@Results", SqlDbType.Int, 4);
com.Parameters.AddWithValue("@Usr", strUsr);
com.Parameters.AddWithValue("@Pass", strPass);
com.Parameters["@Results"].Direction = ParameterDirection.Output;


con.Open();
com.ExecuteNonQuery();
retVal = (int)com.Parameters["@Results"].Value;

con.Close();



return retVal;

Is my code behind is error free? I think I've made some mistake in my code would you check it?

So you know I want that check the username and password user entered, store username in a session and redirect the user to a specific page , and check weather username and password exist in the database or not please insert a sample that I find how could I do that myself.

I changed the code with nvarchar(max) but now stored procedure returns the value "0" instead "-3" or if exists "2" but doesn't do that!

wow thnks, but ,what about to create profile page? Is it an .aspx page, and changes every time a user registered? Or an aspx page is created for every user is registered?

Is any method other than Response.Redirect() for login users?

In fact the things that I don't know is that when a user logged in then what should I do to secure transferring him to a his/her profile?

:( I could not use that, please explain more. What is asmx? I typed in that in google but nothing got me useful.

can use that in vs2008?

ok thank you

Please show me another way to do whithout MVC. A simple traditional way.

Honestly, I dont understand the articles about profiles and membership , because these articles are not compatible with my ideas, and are very complicated.I want to create that by myself with good security configuration. I dont like the default visual studio UI for register and log in wizards.

Better say, a simple complete profile.

My issue is when I want to create a new user I want to create a new page automatically,and that page contains the user information, pictures of that user and so on immediately.

Thanks for your attention,but this type of code is in VB, I want C# one. Thanks

Is anyone knows its solution?:(

So can u tell me that what is server explorer role in thi scenario?because I was defined another database in server explorer and also a table and finally i couldnt work with it. And Also I didn't understand app_data's role. Because , once I copied and pasted my database file in app_data , then in sql server attached it,I received error,and icouldn't attach DB file from even another folder at all ! In addition , SQL server connection and authentication are a little bit complicated,and depends to various aspects that is hard to understand for me!

Thank u,that was not for the technical problems,I've reboot my machine and the problem fixed. My app finally executed.

Because it seems asp suspends while sql respond,I think.

Is this error for connection timeout parameter?

Tnx,i think my problem has solve ,I have mistake in connecting to DB.I've created a DB with the same name(Pubs) and I did not fill in data in tables.;) Because I thought asp connect in to the app_data DB not in sql server folders.Anyway I filled the table now,but when it tries to load the page send me this error:
"unable to start program: http://localhost:1077/ExAsp/Default.aspx
Element not found"

But so why I didn't receive any error about it?also i think did that earlier and I could not connect to DB. Also i hear the app looks for a DB in app_data folder in asp ones.

why i cant attach any database in sqlserver in another folder?I was received error about permissions and so on,and that forced me to use server explorer instead.

I tried that earlier,but I could not attach my database,in another folder like ap_data. But I read in my book that I can do the same in server explorer as good. Second, why in my app. I didn't receive exception once app connected to DB while I didn't attach my DB in sql server express2008?

In server explorer?

Should I did something else other than creating database,place in app_data folder,creating connection string and creating table ,assigning data to that?

<add name="Pubs" connectionstring="data source=localhost\SQLEXPRESS;initial catalog=Pubs;integrated security=SSPI">
this is my string placed in the web.config
Also I tested another application that give the server version,and that worked successfully. I don't know why it doesn't work properly:(.
please help me

I think dataReader couldn't find any data at the table.also i must say that i cant attach database in sqlserverexpress,Im using server explorer as good.
but im not sure every thing is okay about this kind of use.

i have more record stored in the table.
I don't have any message at the lblResult.
also,I said compiler does not go into the while loop

Compile pointer goes to while loop and then jump to the con.close() method. without error.

thanks for your attention,but ,unfortunately i couldn't understand your approach and your code.I'm not experienced enough to understand these partial codes! I was read MSDN and I found a temporary way,a property,Control.CheckForIllegalCrossThreadCalls = false; . This is for .NET Framework 1.1 that also my book is for.But I found that is not an appropriate way for Multithreading programming.But in my this special discussion Threads was not target. Network programming was my target. Although, I'm interested in learning thread,and I request you show me some simpler and more realized samples ,thank you so much.Thanks for your attention.:-)

But still i dont know i should use begininvoke()instead of what ?!and which line?because the error is depending to catch block.I already not used this method,and im not familiar with its params.idont know where i should to use this in my code?

Also,what did you mean "don't even play with the idea of dealing with network"?:(

Hi thanks for your time. First,Im in education,and im reading an ebook,this is a book example and is not my idea.But i cant understand your control.begininvokk()method.what do you mean of it. What control I should to use?and what's place of code that i should to use that?can you show me where I must use that and show me an example?

Thank you very much sir,you are great:**.my problem solved...
