I'm attempting to do a school project dealing with a simple web crawler. I have a form with a web browser control embedded that loads a web page will all the available courses. I have a text box and a button design for a user to search for a specific course by using the four letter department abbreviation. The page that I have loaded has all the department abbreviations as hyperlinks.is it possible to search the page using the four letter abbreviation specified by the user and if the search finds a corresponding hyperlink open it. Then I would use a loop to repeat the process of opening each class offered by that department and obtaining information such as course name, section number and so forth.
View 2 RepliesI would like to click next to go to another image in a picturebox but I only have one picture box setup to have the new letter displayed in it. I have 26 images to display and need to know how to setup a loop to go through each image? It seems simple but I cannot figure out how to get to the third image, it only goes to the second image and stops. I also need to know how to setup the back button to display the prior image in a picture box.
View 8 Repliesi am going creating a simple function calculator, but I had to first do a design documentation proposal. I now have to update the project proposal with a storyboard or list of menu and screen items to delineate my proposed user screen and menus.aside from the calculator itself there will not be any menus.I also have to list any user data inputs and outputs my application will require and produce, which i assume i can put any numbers that the user inputs into the calculator and their results.

I am trying to do a simple editor that would allow you to design the plays. How do I implement a picturebox (picturebox1) with an image in it (lets say image1) then when I drag it image1 will appear in another picturebox (picturebox2)with a basketball court background. Then after dragging image1, picturebox1 will now display another image (image2) ready to be dragged also.
View 3 RepliesI'm sorry if this is in the wrong forum or has already been asked, but I'm having a problem creating what should be a relatively simple code for an Excel Project. Essentially, the code is supposed to check if a certain column has Y in it and then copy that entire row onto another sheet and then move on to check the rest of the original sheet. This version of the code seems to do everything but actually populate the cells with the information. Every other attempt I've made has ended with "Application-Based or Object Based Errors". I've worked on this code for a few days now and I just can't seem to get it right. What am I doing wrong?
Here's the code:
Sub PopulateNewSheet()
i = 2
Do While Worksheets("Main List").Cells(i, 2).Value <> 0

View 3 RepliesI am trying my hand at making a simple poker hand analyzer in VB 2010 for a distance education intro to VB course at my school.My goal is to represent the cards in a table array. Rows are suits Clubs/Diamonds/Hearts/Spades and columns are values (A, 1, 2... K). However I have no clue how to design a Sub procedure that will recognize the hand the user inputs and add any possible results to a listbox (fourkind/threekind/pair/flush/straight/ace high straight). I don't understand how exactly I'm supposed to do this. My criteria isn't very strict. I can have a hand with more than one description, like a fullhouse + threekind + pair can all be used to describe one hand.
What I think I need to do is split the entered string to get 5 strings (each is a card). Then somehow find these in the table? I have no idea how to do this and I'm stumped... The instructions loosely call to look for a boolean value where cards(i,j) is set to 1 of the player is dealt card j in suit i. But I do not know how to achieve this.
As you can see my understanding on VB is extremely... basic (no pun intended). It's my first time ever learning a computer language, and I really regret taking this course via distance ed because the instructor and the TA absolutely refuse to communicate with the students. I am trying my best to practically self-teach with the thick text book.
So i'm creating a simple application as an example that is to link to a Access 2007 database.
On my main form i have four listboxes that are correctly attached to the table, I have one for First Name, Last Name, Phone, and School. I added 3 records to the database in Access to see if I could display the records in the listboxes on the form. I found that it was very easy by setting the properties and I have no problem there. I also have a command button that loads a new form for the purpose of adding a record to the database.
Here is my main form (frmMain.vb)...
CODE:
And Here is the code for the form...
CODE:
What i'm looking for is when the user presses the Add button on the frmAddNew form then it needs to close and the new record is listed in the textboxes and saved to the database. Id also like to know all kinds of things i might be able to do with textboxes and databases because i'm trying to learn for a larger project where i'll need to keep track of hundreds of records.
I understand that this is a simple procedure, but i've been spending all night scouring tutorials and getting lost in the msdn library online, so maybe some human input will be better.
[code]Close to no real programming skills (PhotoShop artist turning Visual Basic Beginner)This is a snippit of the code used in my browser. Basically the items that are in the list box are loaded from a text file hidden in the installation directory so a manager (or such) will be able to edit which websites are navigate-able.Here comes the problem though, I have not been able to get it to work correctly it will not block any of the listbox items. If I can remember it will only block the site which is selected.How can I re-code it to make the program block all the items in the listbox instead of just one.(Also if not too much trouble how can I make something that will enable and disable the code)BTW this isn't a commercial program or anything just a project I have been working for ever at home.

View 16 RepliesI am creating a game which has a simple score system which I don't understand why it isn't working the way I want it to. When loading the game the User starts with 10 credits and for every time they run the game it costs 2 credits
This is my code for this below
Dim intCredits As Integer = 10
Dim intGamesPlayed As Integer = 0
intGamesPlayed += 1
intCredits = intCredits - 2
It has no errors but it doesn't take away the credits each time the game is played besides the first time. So when I run the game it will go to 8 credits, and it will stay on 8 credits even if I run the game again.
I'm trying to create a simple user tracking system so whoever has the program open can see who else has the program open. I know how to retrieve the username and everything. What I was doing was updating (loading and saving) a listbox with a text file on the network with the usernames in it. I can't get it to work right and I think its because the simultaneous opening and saving of the same text file by multiple users. I know this isn't technically the best way to go about doing this but it seemed like it should be the easiest. I don't want to make a huge project out of this because it isn't that important, it would just be nice.
View 7 RepliesI am creating a points system for a game, this is the code I have but it isn't working as I want it to.
Dim intScore As Integer = 10
Dim intNumOfGames As Integer = 0

intScore = intScore - 2
The user will start will a score of 10, but everytime they click the button the user should lose 2 points off the score. But my code above that doesn't happen, when the user clicks the button it only happens once leaving the user with 8 points throughout the game.

I just finished making a Tetris game in VB.NET, and I wanted to add a high score system to the application. So, when a user completes their game, they have the option of submitting it as a high score, which will compare their score against the previous high scores, then place it accordingly. I was thinking of an XML approach of doing this, where the user's name, rank, score, level, and number of lines cleared will be stored in tags. Here is what I thought the XML might resemble:
[Code]...
So the program will have an array to store all the previous scores. It will read through the XML, and copy the the score data into this array. Then, when the time comes to submit a score, it will compare this score against those previous scores, and find the proper position for that score, and then save it into the array. At the end, it will then copy all the score data from this array to the XML, replacing the <Level>, <Lines>, and <User> tags in the process.I am however having trouble implementing this, as I have no experience with XML files and everything I've read has been very confusing.
I think its better if i attach my files for you understand what i wanted to happen in my program.

How to develop a 3 tier soution saying this. If you want to make a simple 3 layer system (3tier is for a longtime complete misused by marketing from Microsoft, 3 tier needs something like a Unix computer) However, do this: start a Windows Form project, then do 2 times File -> Add New -> Project -> Class Library while you name one DataLayer and the other BusinessLayer. While the DataLayer project is selected, you do Add New Item and take the Component (give it the name DataBaseHandling). Then while that component is open. In top Data -> and than what you want to select, however create in fact the DataSet and Adapter in that.
Don't forget to set in your main project a reference using Poject -> Project too your two datalayers. It is easy and don't need all those images, those you will see pasing by doing this. Try to avoid to use your DataLayer in your BusinessLayer which is often done, because then those layers make in fact no sence. i am not an expert The bussiness and datalayer in the same solution really? And when he said: "While the DataLayer project is selected, you do Add New Item and take the Component (give it the name DataBaseHandling)." What kind of component should i choose? and what about the presentation layer? how to call one layer to the other,
