VS 2008 "Pacman" Ghosts Random Direction Choice?
Nov 20, 2009
I've got a small pacman-like game where ghosts are running around a maze. At the moment, their movement is completely random. Each step, they determine which directions they can possibly move in (taking into account walls), and then they choose, randomly, one of those directions.Now, this works, but it's not very good. If a ghost is in a long corridor where he can only move up or down (or left/right), then he will usually not go anywhere, but just move up, down, up, down, down, up, up, down, up, etc. So, while it does move every step, in the long run it doesn't go anywhere.

I am trying to build a pacman game. Currently I am in the process of building the AI for the ghosts. The way I have the AI working is whenever a ghost enters an intersection, it will check where the player is relative to its position,then it will move in one of the possible directions depending on the intersection it is at.The problem I am experiencing though is whenever ghost is moving horizontally it cannot be sent to the left. Similarly,when it is moving vertically, it cannot be sent up or down.This doesn't allow it to turn around when it is moving to the right or to the bottom. It can be sent right when moving left though. When searching through my code I cannot see why this is.

I am having some trouble working out how to make the ghosts chase PacMan. I have made all the code and stuff work with needing a grid maker thingy. I have do in all by placing the walls (pb's) myself and also with the pelets (food). Though I have a problem with getting the ghosts doing their job, they only just change image with a timer tick. Any simple way of making the ghosts chase you?

I have four drop down lists here and I've assigned the datasource and displaymemberproperties so they are populated by a table. When I run the program and select a choice, all four of them get updated with the new choice.

I have created a small sql database using new data source. i have placed buttons to move to next,previous,first and last row but i am wondering if there is a way of making a button which would randomly pick a row with information from database or just make it randomize them before they are appearing on the screen.
At first i have tried creating random number generator and then joining it with the coulmns in the database. I failed in the end even though i thought it was going to work. Then i thought maybe i have to change the query as in, instead of "Select that and that and that from database" i thought i have to write "Select that and that from database sort by rand", i also saw that some people write limit 1 or more afterwards but i have no clue what it is and didnt use it. Anyhow i tried that query and it didnt work.
EDIT: I also thought about adding all questions into array, or use some sort of indexing, but i have to use database as the requirement.
Also if anyone would be willing to give me an advise of what is best book i could buy, which would cover databases in sql and some beginner/intermediate programming in visual basic.

I have a project that needs to open a CSV file that is 3.7gb in size. It is data that was exported from a database (why on earth anyone would export it to ONE file, is beyond me)
Excel/Access can't open the file because it is more than 256 columns and greater than 65000+ rows. I was able to split the file into seperate files with 50,000 rows in each. I wan't to automate this and export only data by a specific state, and perhaps add it to a database or excel file, should the rows stay below the limit.
I found a project that splits the CSV file... perhaps I can just parse the data while splitting the file.

Total noobie when it comes to VB, but I'm jumping in. I have about 15 years with Business Basic and see many similar things between VB and BBx so hopefully the learning curve will not be to steep.
Anyway the project I wish to complete is: Use portable computers running Windows CE 5.0 to scan bar coded labels to capture data collected during a physical inventory. The labels have 2 fields - bin location and item. My form will have a textbox for 3 items - bin location, item and quantity. Also, the form will have 2 radio buttons to accept or reject entry. I plan on writing the records to a simple text file to import in to the current application I am running.
I downloaded Microsoft Visual Basic Express 2008 and have done a little prodding around so far. I know the Express version does not support mobile device application development so that needs to be upgraded. My question is, can someone recommend a good book that would cover the areas I need to be concerned with?
Also, any good online resources?

I currently have my cute little first program made... I'm just stepping into the water with this programming thing. I made a program where you can select a shape from a drop-down list and then input some values and click a button and get the area of the shape. I have it working so that when a certain shape is chosen, certain fields are disabled, such as when you pick "circle" from the combo box, the "length", "width", and "number of sides" text boxes are disabled but the "radius" text box is enabled, thus allowing you to enter the radius and find the area. I want to make it so that when you first load the program, all of the text boxes for the length, width, number of sides and radius are disabled until you select a shape from the list. Currently I'm using
[Code]...
This works for disabling the correct boxes when something is selected, but I don't know if I'm even on the right path with that first part.

I wish to turn on the Single Instance Application choice in Visual Studio 2008 properties. To do so, I must choose "Enable Application Framework". When I do that, my ONLY choice is to choose a Startup Form, not a Startup object. This makes no sense to me. I have a tray application, and I check to see which form I should load, a logon form, or the main form. But since I am forced to choose a startup form, I MUST load the logon or main form to begin with. But I don't want to. I want startup code to determine which one to load first. So then I am playing with making the OTHER form invisible, even if the startup form, but that is a mess.

I'm using SelectionMode as Extended (multi select) with WPF DataGrid.The SelectedIndex value always returns the first row that was selected, irrespective of the selection direction. For example, if I start at index 0 and end at 4, I can work with it fine. But if I start from 4 and go to 0, SelectedIndex returns 4 and I don't have a clue to add the number of selected cells or subtract.Is there a way to find the selection direction?

User of Virtual Basic, as we really just started programming in my Computer Programming class yesterday. I figured that I could use Visual Basic to make a trivia game of some sort to study for various classes and stuff.
The game is set up in four categories based on topic, which each has 10 questions. I have no problem linking one form to another here. However, each question is multiple-choice. To get to each question, you need to click on a button, which changes the label text and all that. The problem I'm running into here is that I need a way to get a message to pop up saying "correct" or "incorrect" for each question. Being that each question will have a different answer, I can't just put "MsgBox("Correct")" under one of the multple choice buttons. I've Googled this, and I've found something with setting values to each button, which I tried, but I must have done it incorrectly.

my question is regarding working out the direction of the smallest angle between two vectors in 2D. I am making a game in C++ where one of the obstacles is a heat seeking missile launcher. I have it working by calculating the vector between the target and bullet, normalising the vector and then multiplying it by its speed. However, I am now coming back to this class to make it better. Instead of instantly locking onto the player I want it to only do so only when the bullets vector is within a certain angle (the angle between the bullets vector and the vector bulletloc->target). Otherwise I want it to slowly pan towards the target by a degrees thus giving the player enough space to avoid it. I have done all this (in a vb.net project so i could simplify the problem, work it out then re write in in C++). However the bullet always rotates clockwise towards the target even if the quickest route would be counter clockwise. So the problem is working out the direction to apply the rotation in so the smallest angle is covered. Here is my code so you can try and see what I am describing:
Function Rotate(ByVal a As Double, ByVal tp As Point, ByVal cp As Point, ByVal cv As Point)
'params a = angle, tp = target point, cp = current point, cv = current vector of bullet'
[Code]...
I had was to work out the bearing of the two vectors and if the difference is greater than 180 degrees, rotate clockwise otherwise rotate counter clockwise

was wondering if you could give me a hand and point me in right direction with the project i am creating. It is a toolkit They are 2 problems that i am having wondering if anybody knew the issues
1. The textbox is not having them 1 by 1 for example
service pack 2
service pack 3
2. The other problem is a bit more tricky, I have software on the hard-drive c:directorysp2
it has to be implemented into the toolkit anybody have any ideas how without a database if possible. I thought this could be done in the load form, pre-loads the software and then checks when comes to installing the software in the list.
