VS 2008 - VB BITBLT Equivlant - Build Image By Opening Files With Image Data

Nov 2, 2010

In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?

VS 2008 Reading XML Files?

May 23, 2009

I am making a program that stores information for my applications. There are 4 main things I need in the XML file, the login information (User name and password), Application names and keys, and the owner of the application (who bought it). The program allows the user to enter as many applications and owners as they want and once login information is correct it loads the data. Then on exit all the data saves to a XML file.My XML file looks like this[code]....

Once I read all that the only thing I get is one application and no owners. How do I make it read all of the Apps then stop at the end of the Application Element?

I have to read SGI Files (I belive it's Suns Raster Image files, they have .rgb extension,but contains no header information), scale it, rotate it and maybe apply anti-aliasing filter to resampled image.I am just trying to read the image file. I read the file in byte array using FileStream and trying to display it in a image box, but it is throwing error while creating Bitmap class from the byte array. My code looks like this:

C# - Reading Guitar Pro Files?

Feb 2, 2011

I was wondering if anybody had heard of a library, preferably a .NET assembly, but Java will do as wel, that allows you to read the data in a Guitar Pro file (.gp3-gp4-gp5)I have this gigantor of a folder with about 50.000 song files, and would really love to write something that can actually archive all these files, for easier searching. And basic information like the tuning of the instruments in the song would be very useful parameters to retrieve from the file and add to the database.

I have searched the web but have yet to find anything like this, or a file definition for writing my own parser.

Reading And Writing INI Files

Mar 12, 2011

I'm creating a simple forms application where users can enter their details and save the information to a .ini file because I needed this for a simple game profile. I've tried to make it write "Name =" + txtname.Text but it won't work anymore. And as well as that, I don't think It will load the text back from the ini file.

Here's the code I used;
Public Class Form1
Dim hFile As Long
Dim sFilename As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....

Form designer: [URL]
Form1.resk: [URL]

Reading Sequential Files?

Mar 2, 2010

I am suppose to create a module level array name Product and populate a list box with the contents of a file (ItemInfo.txt) The file contains the Item ID and price of the item. (Line 1 is an item, Line 2 is a price for Line 1, Line 3 is an item, Line 4 is a price for Line 3, and so on.) The problem i'm having is when i populated the list box, I only wanted to populate the list box with the items, not everyline from the file. I guess I wanted to put elements [0], [2], [4], [6], and [8] from the Product array in the list box, but I am putting everything in there. What am I missing?here is my code so far:

' Name: Glovers Project
' Purpose: Displays the price of an item

Writing/Reading .dat Files?

Dec 28, 2009

seeing as '.dat' files contain only what you want them to and there is no preset encryption for them etc could I write data to one by using this simple process:

1) Change file extension to '.txt'
2) Decrypt
3) Write
4) Encrypt
5) Change file extension to '.dat'

and pretty much the same for reading it. or am I thinking to simply?

I thought of the above way as i know how to write to text files already, but is this the best way to do it? or is there a better way?

EDIT: Nevermind you just write to it like a text file and encrypt/decrypt it. request lock/delete from mod.

Reading Cell Values In An Image?

Mar 10, 2011

I want to read the values of the 8 neighboring cells in an image as shown on the attached file. For example, the green cell is the home cell and it has 8 neighbors (cells from 1 to 8 as seen on the attached image). It will read all 8 neighboring cells then it will move one cell to right (now pixel 4 will be home pixel). Again it will read its neighboring cell values and then it will move to next pixel etc. It will continue till to the end (the last cell or pixel of the image).
