The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

I have an aspx page that runs a stored proc. The stored proc returns a value ( a record ID) after performing a few insert statements. I want to get that return value with vb code. My current code (see * below) gets an error message: "Input string was not in a correct format." I can't find the right code to get the return value. What is the flaw(s) in my code?

Thanks for looking.

The stored proc:

CREATE PROCEDURE [dbo].[CreateEval]

	  , @EmpLastName varchar(30)
	  , @EmpFirstName varchar(30)
	  , @EmpDepartmentID int
	  , @EmpJobTitleID int

I am writing a C# console application using VS2015 and .NetFramework 4.5.
I use a foreach loop as follows and it works fine.

However, I was told that the directory I am currently using will now contain other files besides the files that my program processes.

My program should only process the following 3 types of files:

The # symbol means the value is a number. Thus, the first 2 files names have a prefix of 30 numeric characters

1) ##############################_Rear.TIF
2) ##############################_Front.TIF
3) FargoChkImg######.xml

Can you think of a way to bypass all filenames except the 3 filename types shown above in the following snippet of code?

foreach (FileInfo file in parentDirectory.GetFiles())
{
try
{
if (file != null && XmlFile(file.FullName, sw1))
{
sw = new StreamWriter(goodFilePath);
ProcessFile(file.FullName, sw, sw1);
}
else if (!hasElseBeenExecuted)
{
hasElseBeenExecuted = true;
sw = new StreamWriter(emptyFilePath);
}
}
catch (Exception ex)
{
sw1 = new StreamWriter(errorFilePath);
sw1.WriteLine(ex.Message);
if (sw1 != null) sw1.Close();…

Hello Experts,
I have a Windows Service program in C#, 1. which is attaching a xxx.txt file in an email attachment, and 2. should delete it after that. Only the first part of the program is working. At 2nd part, I am getting the exception "The process cannot access the file XXX because it is being used by another process". At this point the file has been locked #1. Any idea how to fix it? Thank you very much in advance.

This is how I am trying to delete the file. At this point if I change the folder name and try to delete the file it works fine.

Array.ForEach(Directory.GetFiles(filePath), File.Delete);

Thank you !

How do I do a simple POST and GET in C# to pass/retrieve values?

I'm used to being able to use session variables or (in an older application) the authentication provided by ASP .NET to control security/access within my web app. Now, for a couple of reasons, I need to POST and GET data between pages but I'm struggling with how this is done. I need a simple way,using C#, to POST some data from one page and then GET (process/retrieve) it on another page. Can someone provide me with simple clear examples or code for how this is done? I'm using VS 2012 and 2015.

I am developing an ASP.NET application using C# with VS2015 and .NetFramework 4.5.
How would you revise the following "FileInfo" statement to read in files that are formatted as
exactly 20 numeric characters followed by a period followed by "tiff"?

For example:
20170908429205658805.tiff

FileInfo[] fi = di.GetFiles("*.tiff");

In a simple ASP.NET Core 2 Application in which I am using CodeFirst, I am trying to run Update-Database command in PackageManger Console Window (an InitialMigratio has already been created successfully). However I get the followin error.
Keyword not supported: 'mulitpleactiveresultsets'.
I suspect there is probably some erroy in my Connection String in my appsettings.json file.
The ConnectionString I have in appsettings.json file currently looks like this.

"ConnectionStrings": {
"Default": "Server=(localdb)\\mssqllocaldb;Database=Webroute;Trusted_Connection=True;MulitpleActiveResultSets=true"
},

I would appreciate if could let me know if there is any error in the way I have defined the connection string and if the ConnectionString is correct what could the cause of the error message (Keyword not supported: 'mulitpleactiveresultsets'.) I am getting and how could I fix this.
Thank you for your help.

The complet appsettings.json file in my project looks like this:

Hi,
a client has requested me to develop an Intranet site using Visual Studio 2015, ASP.Net C#, MVC5 pattern and SQL Server 2012 R2. Users from this company speaks in English, Spanish or Portugess, so they need to access the new Intranet app in their corresponding idioms.
The only thing that really complicate me is how to add the multiple 'Idioms' support.
The request is that the site be developed in English as the default language but more idioms will be added, initially "Spanish".
This client showed me a couple of intranet applications that support this function. In one case, the app adds a folder with the idiom name, "spanish" for example, and have kind of txt files with translations in it.
Another app contained translated pages, for example, "login_eng.html" (English page version), then other called "login_spa.html" (Spanish page version) and then other called "login_por.html" (Portugues page version)
Other intranet app He talked to me uses the "Resources" from Visual Studio, as he said (I did not see this one).
So I am now confused, what is the best approach or practice to add Idiom support to an asp.net C# MVC Intranet application?

Can anyone take a crack at this? I have a repeater that is not getting populated from database

Greetings again,

I have a repeater control called Repeater1.

Users are given two submit buttons.

One submit button allows users to fill out their forms and submit to the database.

The second submit button allows users to save their work and come back to complete the form later.

These submit buttons work.

When a user click the Save and finish later button, when s/he comes back, we would like to display the records already submitted so user knows where to continue from.

I have a stored procedure that pulls data from the database to populate the Repeater form if the record exists.

When I try to run the code, I get the following error message:

DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'RegNo'

Any ideas what I am doing wrong?

Here is some code snip:

//Stored Procedure:

CREATE PROCEDURE [dbo].[uspGetRecs] @pin int
AS
select RegNo, VRegNo, RetdVal,TRetdVal
