VS 2008 Noob Direction To Get Started?
May 21, 2009
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 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.

I have been developing with VB6 for about 7 years now, and I think it is time I move on to VB.Net to future proof my skills.Not only that. I am learning C++, but that is beside the focus of this post.Anyway, So I installed the VS 2008 Professional, I didn't install all the Windows Mobile SDK stuff, Just Visual Studio, MSDN, and the sql server...
I do a lot of work with HTTP requests from within my applications, like building GET and POST requests and returning strings that are parsed and what not...I was using the winHTTP COM object in vb6 for the longest time, and I loved it... It was structured nicely and when Dimmed "with events" opened up a nice way of implementing progressbars, calculating download speeds, etc etc...
1) What is the .NET alternative of the winHTTP COM Object...
2) How do you dim objects withevents globally across a form class?
In vb6 I would dim my winHTTP object at the top of the form with events, and then I could implement all my progress bar code in the winhttp events that are exposed....Also then in each subroutine you then have to set = new winhttp.winhttprequest to create the new object, blah blah blah...

I'm a complete programming nublet.I got nothing.But I'm trying to start learning. I figured the best idea was to figure out some things I'd like to be able to automate, pick some that sound relatively simple, find code that does it, and start picking it apart. I haven't found what I'm looking for on this one, so I figured I'd ask here.
What I am trying to do, is create an exe (so it can be run remotely with admin priveleges) that will read a file, determine if a couple lines exist, and if not, will write them in the correct spot in the file.
Am I being too ambitious on this? Can it be done? Can someone help me with how?

I have a text file that I am reading from which is a list of first and last names. They are in order but they are on different lines of the text file. I am trying to read them into an array and put the first and last names together on separate lines.

I know there's ton of examples on the forum but i could not get it to work the way i want.
Sample CSV :-
Unused,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
And what i wana do is change the Unused to Used so basically once this is done it will look like.
Used,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
One thing to mention is i dont want to loop through the whole file and change all the Unused to Used. So basically software fires up opens the file and looks for Unused and changes it to Used and does the rest of the function and shuts down. Next time the software is fired up it goes through and does the same thing.

how to PROPERLY make a multi-tabbed or multi-window application that can handle file start requests.
For example, on startup my "Desktop Application" runs and sits there waiting for a task, either through the main menu, or for a file to display in a window. Now the problem is simple, how can I make this already running program load the dropped file (dropped on the executable (!)), instead of starting a new instance.
I understand I will have to check if the process is running, and if so, do some stuff with it. But the problem is passing the message to the active program.
Previously I used text files with paths/arguments in them, but I don't like the idea of the OS/program checking every 500 ms if a file is created in the "load this" folder...
Then I thought of sending a message using "Send Message", for example changing the text in a textbox and handle the "Text Changed" event, but is this reliable? Can any other program interfere with it?
So, basically I need the proper way of doing all of this. For example, Microsoft Visual Studio does this nicely, and no lag whatsoever...

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'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?

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.

Trying to create a custom button to reside on the desktop at:
Me.Height = PictureBox1.Height
Me.Width = PictureBox1.Width
Me.Top = My.Computer.Screen.WorkingArea.Height - Me.Height
Me.Left = My.Computer.Screen.WorkingArea.Width - Me.Width
The trouble is all the arrows point to right, and the menus open variably depending on size.
Is there anyway to make the arrows point left and make all menus open to left in same direction?
Also, Is it possible to make the width of my form autoresize to the size of a label and the image box, while keeping the imagebox at the bottom right of the screen showing the populated label to the left?

I have some lines drawn in many different directions (2D y 3D enviroments). Is there any way to draw text oriented along the direction of each of these lines? It was an easy task in former versions of Visual Basic, but now it looks like a very tough -almost impossible- mission.
