View 1 RepliesI am just wondering if there is any way I could copy a bit of text using whatever application, but having a clipboard application of my own to store all of those on a listbox? So if it possible, how can I catch a value when I the user copies some text? I could make a cool application that would be quite handy... is there any event that could catch the data when something is copied onto the clipboard?
View 14 RepliesI have some info in a listbox on another form. I want that information parsed to another form, and I would like to, for how ever many items there are in a listbox, create a button for every item and obviously parse the name to another label. I guess I would do this via an array.

View 14 RepliesI am trying to store confidential encrypted user information for my program on a single computer. I do not want the application to be copied on to another computer and be usable. So I was thinking about storing the information in the Registry but I read that that is a very unsafe location and is bad for more reasons then one. I started storing the information in the programs Settings.config file but I am not sure how to encrypt that information. The only thing I have gotten to work so far is storing the information in a XML file and encrypting that which has worked but I want the information to be more hidden and more secured.
View 9 RepliesI was wondering how you can copy information (from a webpage, for example) and store it in a string?Also, how would I take only one word of the string if there are spaces between words and I will always be removing the word with the same location in the string (for example, the last word in string).

I had been doing a split function after the ":" but, that doesn't turn out so good once you add in file paths. I have turned to trying to grab the first ":" from the left using the "InStr" function which returns the char integer. I need a way to grab all the information on that line after the first ":".
I have an ASP.NET application. It resides within another ASP.NET application. I put my DLL in the other apps bin folder and have a subdirectory with my aspx files. I can't edit the main app's Web.config.
So where can I store configuration settings? For example, this is an app that will get deployed to various clients. I want to store the client name used for display in the headers and such. And the location of a logo file.
I am new to development and I am looking for some pointers. I have a sql 2000 database and a vb.net app. Right now the SQL username and password to connect to the database is stored in the VB application which is not convenient since we must change the password periodically. The user opens the app and enters the username and password for the vb application. Using the credentials stored in the application to connect to the sql server, the app checks the username and password stored in a user table in the database to determine if they are allowed to connect or not. For various reasons, it is not feasible to simply have the application username and password be the same as the database username and password. We must have only one database username and password and it must be changeable. Like I said, it is now stored in the compiled application which is inconvenient.
View 1 RepliesWhile trying to find an answer to my question, I came across a project called OTSe, which allows people to make they're own online 2d online games. The system is based on an open X, Y, Z square tile map. For the sake of easy understanding, lets say they're are 3 types of tiles. Tiles you CANNOT walk on, tiles you CAN walk on, and tiles that SLOW YOU'RE CHARACTER DOWN.The project team has created a API class for users to work with in order to develop tools. What I'm trying to do, using they're classes, is GET the all the tiles on the current floor I am walking on, and then display them in a tile grid on my form, changing they're color depending on what type of tile they are. If the tile is NOT WALKABLE, make the tile gray, if the tile IS WALKABLE, make the tile brown, and if the tile SLOWS YOU DOWN, make the tile red. I also need it to store the information of each tile, since tiles are objects, and have properties.

In my application I want the user to enter information that can be stored in BOTH an SQL database and and Excel spreadsheet. I tried research but can't find the code to include or import Excel
into my project.I've seen examples like:
Dim excelApp As New Excel.Application
Dim excelWB As New Excel.Workbook
etc....
but VB doesn't recognize it as a shared namespace. Is it possible to load a spreadsheet into a VB project with express edition?

View 4 RepliesI need to have the ability to have a Global variable/class that stores some basic information about the currently logged in user including that user's preferences, security rights, UserID, etc. This information will be needed by any/every part of my application. In the past I have either used a Public variable/class in a vb.net module for this purpose. I'm trying to get away from my old ways of doing things and was curious what people currently do for this functionality.
I am thinking a singleton or 2 regarding preferences and security but am not sure if that is the best way to go.

I want to build an application using VB, that is essentially an information system.The operation of this system would be as follows:1. User can select one of several buttons, each button being a different topic.2. When a button is selected, information about that topic appears on the right hand side of the form.3. The system allows information to be added by a user So, for example, if a user clicked on the button named 'Banana', information about the banana would appear on the form, where the user could read this info, scroll down etc.I would also like the user to be able to search a specific word like 'apple' and for information on the apple to appear.How could I implement this? I don't know how I would store paragraphs of information, and then search for it based on a keyword.

All things point to a database but for several reasons I can't use a database.
I am writing a VB 2008 program to display and update records from a sql database. This particular form is used to display and modify retail store information records from the database. I am running into an issue with saving the records once they have been changed.The error message I am getting is "Update requires a valid update command when passed DataRow collection with modified rows". I am including all of my code for the form because I am not sure what is relevant. I am getting the error when SaveTheEdit() is called on line 83. [code]

Basically i am creating a console application that will create and store client information as a .txt file it is going okay but i have come across a slight hick up i want to use something on the lines of this .....
dim lastname as string
Do Until Integer.TryParse(Console.ReadLine(), LastName) = False
Console.WriteLine("Invalid input, Please try again")
Console.Write("LastName:-")
[code].....
this works fine to trap out numbers from letters but the problem i am getting is when the program calls uppon LastName it is recording 0 and wanted to know if there is a way of getting past this ..... so basically i need a way to allow letter but not numbers and symbols and then dispay a pernolised error message but at the same time use Stream writer to save was the answer is in a .txt file.
The idea is that I have certain values stored in textboxes/listboxes and thus can I store the information in a spread sheet. And if I change the value in the spreadsheet can it also change the value in the application? I had one idea which was to make both store data in a txt file and read from that, but I'm not quite sure how to do that either.

View 39 RepliesI am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
