We have a current implementation of a log file manager where it's two main purposes are to 1. rename files generated by other programs with a date/time stamp so they create new ones, and 2. delete files older then X amount of days from a specified folder. The program also makes it's own log file which records when these events happen.Do you think the Logging Application Block would be useful in this instance? The old file manager is written in VB 6.0 and an upgrade to VB .Net would not take too long, but is it worth it to try and implement LAP into it?

We are trying to store DateTime values in an Oracle Date field. However, the precision is being lost. Currently only the year, month, and date are being stored. We need better precision than this.
Oracle Dates are supposed to "includes not just the month, day, and year, but also the hour, minute, and second. "
i m trying to generate a large random block of characters(lets say 100 characters).This below is the code i used to generate a letter but to generate lots of characters(letters) i couldn't.I then wish to display them in a RichTextBox:::
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim rand As New Random Dim letter As String letter = ChrW(rand.Next(Asc("A"), Asc("Z") + 1)) TextBox1.Text = letter End Sub End Class
I am using VS2008. I worked on this problem for a time, but I was not successful doing it. Below is the VS file.I need to produce a grid of cells and have some random features as shown below which is an example of a world of (500 x 500) units (or any other size and grid size). It contains three areas (of 11 cells, Value of each cell = 108), two green areas (of 8 cells, Value of each cell = 137) and one river. The start point of the river should start from one of the world edges and finish to another one. Please note that number of feature could increase or decrease according to user inputs.The question is, how can I produce these features randomly? To clarify the question, I will read the number of areas from a form. I need these features so that the number of cells should be distributed randomly beside (attached to) each other in the world. The rivers occupy one sequential grid line. My problem is how can I randomly generate the features according to number of cells??
I need to activate SSL when my application logs on to a ftp server. I'm searching the net and I can't find some piece of code to work, the username and the password are in plaintext, they are visible
I use this for now but it doesn't work:

you tell me how to make a ClickOnce Application Start when A User Logs on? I am running Express so I cannot use the Installers in the full VS. I would like it so it will only add a shortcut when it is installed. (Application is available offline)
Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)
I am trying to make an application which logs on to a server using the telnet protocol runs a couple of commands and stores the output of these commands in a text file.The problem is that I cant really seem to figure out how to negotiate the telnet commands. I have done a packet capture of a telnet session todifferent servers using a packet capturing program and I dont seem to find any fixed pattern. Every server negotiates the command in its own different way and in a different sequence, moreover the commands exchanged are not the same.
What I want to do is to exchange the bare minimum commands which will allow me to log on to any server via telnet, run my commands, take the output and logout.I have searched the internet for such a set of 'general' telnet commands but I wasnt able to find any.
the rules are that same coloured blocks of two or more can be removed by clicking on them. blocks then slide down from above. if a column is empty columns other columns move in from the sides.when someone clicks on the green blocks in the bottom row the columns should slide in from the sides. columns to the left of the black line slide right and on the right of the black line slide left. so in this case only the two rightmost columns should slide from the right to the black line after removing the green blocks.The problem i am having is in designing a suitable algorihm to do the collapsing after the removal. my current approach is to test each column from left to right to see if it is empty. if it is empty then i slide whatever column is to the left (if left of the black line) or to the right (if to the right of the black line) over the blank column and repeat this in the direct i am sliding from
i am creating a programme for my institute which helps in their administrative process. i am using visual studio(basic) 2010. which is connected with ms access database (abcdata.accdb) the database is having table called session with columns sessionID,sessioncode,sessionname.
* sessionID data = 1,2,3,4 * sessioncode data = 13,14,15,16 * sessionname data = 2013,2014,2015,2016

other then this u can see i want this because i am trying to create a database which must save the students data year wise, so that whenever we need to know a detail any students then we can find with query.
I have asked questions about this before but my program has came to cross roads where I require more flexibility in my security procedures.At the moment I generate a specific key based on certain details about the system, and I hash this data to file, which ensures it will only run on this system.
However it has now got to the point where I have a need for providing keys which will carry settings for the program within the key. So that if a customer wants an update its the matter of sending an updated key, which will allow certain areas of the program to be unlocked/locked.Obviously I can no longer use the hash, as it can't be decrypted. I am looking to use key encryption system, which will allow to encrypt data within a license key. But obviously it brings the problem of where to store Crypt & decrypt key within the program.
i'm developing a web application. i want if user access it, it will prompt for windows authentication, if the username and password is correct, then the page appears.i've been working around on this but it's not working. my web app prompt users for windows authentication, but it always failed or access denied.anything i should check?
I'm working in .net environment (all versions) and using vb.net. I want to generate RSA public and private keys based on a passphrase. RSA algorithm only limited by using a class provided by the .net ie System.Security.Cryptography.RSACryptoServiceProvider Class. I know how to generate random RSA public/private keys and perform encryption/decryption.But that .net class don't let us creating RSA public/private keys based on a passphrase.
Using visual studio (Winforms) with sql server (R2). If you can login by inserting the correct values in the textfields (vb.net) that is connected in the database . How do i code the log out?
I've made an application and it connects to my database. But the issue is the details of the database can be found out through packet logging or something. How can I stop this from happening and secure it, without having to have a third party such as PHP script etc.

I currently have a simple crystal reports application which generates a crystal report and in the built in viewer provided by VS2005. There is a drop down where you can select options to change the criteria of the report. I wish to convert this app to a windows executable which will take all those select options and generates pdfs based on the crystal report. the executable will be triggered by windows task scheduler...or maybe command line app?
Obviously this will be somewhat of a re-write. What would be the best way to start this as? a crystal report application or a windows application.

I'm having a problem with some users, my vb tools always check at the splash screen a response from a server with a simple:
Dim MyResult as string = oWebclient.DownloadString("www.mydomain.com/page.php")
This actually works for most users but in some clients the firewalls I think they block this call or bypass or something like that, I found that after telling the user to turn off the firewall everything works ok, now I have some users that according to them they don't have a firewall or they already disable and still they have the problem.
You can see from the image the error message they receive, so my question is do you know any kind of free tool that I can send to the user to maybe log what program or whatever is blocking the program to connect?
