Just paste it in and a popup will appear where you can pick code. Or, click the code tag in the toolbar of the editor.

You are right

Also we can tag

which automatically comes when you copy paste or write the code in code editor

Re: Regular Expression to get only the first 30 alphabets from a big string

2-Nov-17 9:37

Hi,

I am trying to use a string compare with a static string with a File name, the File name is very big like this: "BSC_gMax_BSC_gMax_PROD_20170721001923.xml_EXCEPTIONS_b77022d0-7176-469a-9e83-5182b59a0cba.xls" but I want all the 31 Alphabets irrespective of case from the file name to compare with the static string I have

For example I want to check the string which has 31 alphabets: BSCgMaxBSCgMaxPRODxmlEXCEPTIONS is satisfying with the File name, then return true. I can only use the regular expression though because its running dynamically.

I tried the following: "[a-zA-Z]{0,31}", "[a-z]+" and "[a-zA-Z]{0,31}$" none of them worked for me so far though, but any advice and suggestion going to be very very helpful. Please I can only use regular expression, I am also searching but if you are familiar it would be great help thanks in advance my friends.

Thanks,

Abdul Aleem

Hi
I'm not the world's greatest expert in regex, but

JavaScript

[a-zA-Z]{1,31}

will return all the matches you want - you can test it on regex.com[^].

After that, you need to concatenate them into a single string - this Stackoverflow[^] page may help you with that.

No need for a regular expression - you just need to extract the letters from the string.

With LINQ:

string input = "BSC_gMax_BSC_gMax_PROD_20170721001923.xml_EXCEPTIONS_b77022d0-7176-469a-9e83-5182b59a0cba.xls";
string output = new string(input.Where(char.IsLetter).Take(31).ToArray());

Without LINQ:

string input = "BSC_gMax_BSC_gMax_PROD_20170721001923.xml_EXCEPTIONS_b77022d0-7176-469a-9e83-5182b59a0cba.xls";

char[] buffer = new char[31];
int bufferIndex = 0;

foreach (char c in input)
{
    if (char.IsLetter(c))
    {
        buffer[bufferIndex] = c;
        bufferIndex++;
        
        if (bufferIndex == 31)
        {
            break;
        }
    }
}

string output = new string(buffer, 0, bufferIndex);

.net web form application using javascript

dcof31-Oct-17 5:33

In a C# 2010 web form application, I have found some JavaScript statements that will not allow the application to execute when I am using the Internet Explorer browser since some of the objects are obsolete/deprecated. However when I run the application using Firefox, I find that the application runs. I have also noted that some of the Javascript objects in the web form application may be deprecated in the future and to use these items with caution.

Thus if I deploy a new version of the current web form application and tell all users to only use Firefox in the next few weeks, I will create a static executable that everyone can use. Then when some of the objects are not allowed in Firefox, the application will still run since I have not changed the executable, correct?

Would I need create a new version of the application with the Javascript changes that are required?

If this is not true, would you let me know why and potentially what I should do to solve the issue?

I don't quite follow what you are asking, but if you find you are using old JavaScript that some browsers no longer support I suggest you update your code to be current. In my opinion, there is no need to create a new version of the application, just update your javascript and deploy the updated javascript.

I am not very familiar with javascript. I only know enough to make minor changes. Thus how do you copy the javascript files? I know that the files end with .js and they are at various locations within the entire solution file. Wouldn't I have to copy all those files to the same directory structure on the server that hosts the website?

Yes, but aren't they already there? So, if you change one file in development you only need to copy that file to production.

Since the error says that the login has failed, you should ensure that the user ABC\ABCWL753274$ is a valid login and database user.

Remember that if you use integrated security, the connection is opened using the credentials from the background process.

ABCWL753274 is not my user name its just my machine name, is it trying anonymous login that's the information I am looking for. But the ABCWL753274 is just my machine name as far as I know.

My connection string is as below, is there any problem in my Connection string:

<add name="InventoryDashboardEntities" 
     connectionString="metadata=res://*/IBDashModel.csdl|res://*/IBDashModel.ssdl|res://*/IBDashModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=xxxx569s,xxxxx1;initial catalog=InventoryDashboard;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework&quot;" 
     providerName="System.Data.EntityClient"/>

Is there any problem in the above Connection String?

But if I use the below Connection String, its giving me the error as below:
<add name="InventoryDashboardEntities"
="" connectionstring="Data Source=WSQL569S,50101;Initial Catalog=InventoryDashboard;Integrated Security=True" providername="System.Data.SqlClient">

The error it is showing is:

The context is being used in Code First mode with code that was generated from an EDMX file for either Database First or Model First development. This will not work correctly. To fix this problem do not remove the line of code that throws this exception. If you wish to use Database First or Model First, then make sure that the Entity Framework connection string is included in the app.config or web.config of the start-up project. If you are creating your own DbConnection, then make sure that it is an EntityConnection and not some other type of DbConnection, and that you pass it to one of the base DbContext constructors that take a DbConnection. To learn more about Code First, Database First, and Model First see the Entity Framework documentation here: http://go.microsoft.com/fwlink/?LinkId=394715

The connection isn't anonymous. Looking at your connection string

indian143 wrote:
...;integrated security=True;...

you're connecting using the credentials from the running process, IIS in this case.

As said, you should ensure that this is a valid login and user or switch to SQL Server authenticated login.

GridView New Record from Empty Cell

Member 1130123127-Oct-17 9:35

27-Oct-17 9:35

Hello all,

I've been trying to wrap my brain around how to do this and coming up with nothing. I'm a beginner developer and creating my first .net MVC site for a company project.

I have the following tables: Projects, CalendarDates, and Bookings.

The bookings table accepts the cross ref between Projects/CalendarDates and has a field for booking value.

I've successfully been able to create the grid view with the list of projects by row with datas across the columns. This works perfectly.

What I want to do is make the entire table editable and if there's an empty cell, create a new record in the bookings table based on the Project Row and Date Column it intersects.

Hi,

I am writing an online trading and classified web application, I am going to have online payments methods in it, they can store that information, so I am looking any advice from all buddies for security and encryption and many other things that can make the Web site vulnerable anything please advice me whatever you have my friends.

Thanks in advance.

Honestly? If you're going to be storing people's financial information (credit card details etc) and you have to ask, then... don't. Or find someone with experience to work with on this project - do not try to wing it yourself. This is other people's money and livelihoods you're playing with. But do you really need to store sensitive data yourself?

You will need to use https / SSL.
You will need to encrypt data securely.
You will need to work with someone who knows what they are doing.
or
You will need a good lawyer.

Yeah I will use all the above and except Lawyer, but just in case I will keep the Lawyer also in mind. But sure thanks and I will never go live until we are sure we have all the Data secured etc. Not only that I will get more and more suggestions even meet with more number of people. Thanks my friend.

Even-though I work with others but still I want to have more information even to know and understand if the person I am working with is doing right or not?
Can you please elaborate about the following two things you mentioned above my friend?

You will need to use https / SSL.
You will need to encrypt data securely.

I am planning to deploy the site on GoDaddy, is it better approach for SSL and is it safe if I do it or should I have dedicated Servers for my website? Having dedicated Servers initially would be more expensive but eventually we can do it but does GoDaddy work or do I need to go for Azure? Which is the best and price-wise reasonable for us, because its a startup so want to go one step at a time, not planning to spend all at the same time and be in loss - please understand it my friend.
Can you please suggest me better things for the Data encryption as well? What are the best possible options available I am not saying I am going straightly into it, but I am just starting to learn more and more.

Thanks,

I am reluctant to start giving advice on this topic as I don’t regard myself as an expert in it. All I need to secure is user logins for sites hosted on my Cloud server and running under https. I use a third-party tool (well, class) for hashing the passwords, and 2-factor authorisation for logins. So far so good (not that anyone would be terribly interested in hacking these sites anyway – the reward would hardly justify the effort!)

I don’t know about Godaddy – I expect they can offer you SSL certificates for your site, but personally if I was going to be holding really sensitive information I’d prefer to host it on a server I had full control over rather than a shared platform. A shared platform also means a shared database…. I would also employ someone who is an expert in I.T./data security. Examine their CV and follow-up references to assure yourself that they are genuine and up to the task.

IF I am not mistaken many, if not most, Cloud server services have a free tier, which will likely offer enough features to get your startup started, and cheaper than Godaddy. Hunt around.
