Loading Images With Different Filenames Using One Line Of Code
May 27, 2011
I am currently new to visual basic and I am using Microsoft Visual Basic 2010. I am trying to create a small game in which i want to use 8 images. These images are imported in my resources under images as _0.gif _2.gif up to _7.gif. I could write code for each of the imageboxes individually but i prefer doing it in an array as shown below. As you can see I use the variable "i" to run a for, next loop.
picbox(i).Image =
My.Resources._1
So that not every time it loads the image. _1.gif but it loads the images _0.gif through _7.gif, based on the "i" variable.
For
i As
Integer
= 0 To
7
picbox(i) =

the best method to read a huge file? I'm guessing its with "stream"?It's like a 200mb file.I need to read each line and do something if the line contains a search string.
Code:Imports System.IO Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim strFile As String = "c:
I am using the given code to copy my database files...it works like a charm in debug mode but as soon as I create a setup, it stops working. The error is
"Database Detach Failed"
I tried checking the code line by line and found that the code does not enter the IF block.I have no idea why.
Public Sub bk() Try Dim strDatabasePath As String = My.Computer.FileSystem.CombinePath(My.Application.Info.DirectoryPath, "LIC.mdf")[code].....
As you see the code given below is not very useful. Is it possible to shorten the code. Mousewheel back and forward give the same result (next image). Keydown cannot be configured.
Private Sub Images_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load count += 1 If count + 1 > ImageList1.Images.Count Then [Code] .....
I have about 100 PNG images stored in a Resource. Sometimes I need to have the same images in an ImageList, but I do not want to store the images twice in my application, so I add the images from the Resource to the ImageList during runtime when I need them.
Is there an easier way to do this than having 100 lines of code, like the small example below?
I am using the following piece of code to load images as thumbnails to a FlowLayoutPanel control. Unfortunately i get an OutOfMemory exception.As you already guess the memory leak is found at line
Pedit.Image = System.Drawing.Image.FromStream(fs)
So how could i optimize the following code?
Private Sub LoadImagesCommon(ByVal FlowPanel As FlowLayoutPanel, ByVal fi As FileInfo) Pedit = New DevExpress.XtraEditors.PictureEdit Pedit.Width = txtIconsWidth.EditValue
[code]....
Update: The problem occurs while loading a number of images (3264x2448px at 300dpi - each image is about 3Mb's)
Is there any efficient way to load all of the images that my program will use upon start-up such that when I load those images into pictureboxes during runtime regardless of what form I may be using, the images will load faster?Does that make sense?I've read about ImageLists, but do they actually load the images or is it just a way to manage image files?
I want to load images into a picturebox, save them into a database and display them again in the picturebox. This is the code I'm actually having problem with:
Private Connection As String = _ "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:UsersclientDocumentsVisual Studio 2008ProjectsSavingsLoansCalc.mdb" rivate Sub UploadButton_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles UploadButton.Click [Code] .....
I'm getting this error message: "Type 'Connection' is not declared" On this line: oConn = New OleDb.OleDbConnection( _ New Connection().getConnectionString)
I have a 4 pictureboxes for a database I made but having a problem with loading images in to the picturebox. On my form I have a picturebox, 1 button, 1 textbox, and 1 openfiledialog.
My button click event code Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click OpenFileDialog1.ShowDialog() TextBox1.Text = OpenFileDialog1.FileName Pic1PictureBox.Image = Image.FromFile(TextBox1.Text) End Sub
I can add pics but if I don't select any image (just close the dialogbox) I get an error and not sure what to do ..or what to add. Is there any code to tell it to just close..
I'm trying to load this image file on a PictureBox but I get an "OutOfMemoryException was unhandled" error.
How do I allocate more memory for this? Or maybe use another container? My project's main feature is loading maps, unfortunately my boss wants to load the whole map and won't accept sliced version of the map.
i'm working on a project right now and I need to create a graphic library.The game I'm experimenting with is an RPG; this project is expected to contain many big graphic files to use and I would prefer not to load everything into memory at once, like I've done before with other smaller projects.So, does anyone have experience with libraries such as this one? Here's what I've came up with:
Have graphic library files and paths in an XML file Each entry in the XML file would be designated "PERMANENT" or "TEMPORARY", with perm. being that once loaded it stays in memory and won't be cleared (like menu-graphics)The library that the XML file loads into would have a CLEAR command, that clears out all non-PERMANENT graphics I have experience throwing everything into memory at startup, and with running the program running with the assumption that all necessary graphics are currently in memory.
I'm currently blocking all the images from loading in the web browser control by using the registry key. I would like to find a way were I could allow images from some sites to be shown.
i have a simple photo viewer application where i want the user to click a "load sequence" button and then i want something like a folderbroswerdialog to appear then the user can pick a folder with images in it then the images get loaded into the picturebox and the user can click a "forward" button to go to the next image in the sequence and a "backward" button to go to the previous image in the sequence, it's kinda like windows 7 photo viewer.
Display ajax loading image before loading anycontrol .... means if i wanna show textbox on button click after showing loading images using ajax toolkit or ajax extension in vb.net ?
I've got a Program and a text file, this text file gets load into the list box but that's not the problem. The problem is that when I make the text file it makes a open line and this line gets loaded into the list box and I don't want empty items.
So here's code that I use to make text file Public MySettingfile As String = My.Application.Info.DirectoryPath & "Process History.MemFreo" Dim myCoolWriter As New IO.StreamWriter(MySettingfile, True, System.Text.Encoding.Default) myCoolWriter.WriteLine() myCoolWriter.Close()
I am using WebBrowser1.DocumentText to get a websites source code, and then parse a string. I am trying to view the source line by line, and doing it as follows:
[Code]...
However what is displayed is each character from the source code, rather than the line. I am making the client log into a website, and the needed value from the source code is then parsed, so I need to use the WebBrowser type to get the source code.

I have this string just down loaded of a Unix server. I would like to remove the box (0x0A) Unix end line code; then replace it with CR+LF normal ASCII code. Also, I would like to do the replace before I save the data, while it in memory.
I found myself a difficulty on creating a image uploader to my database. This is because in .NET CF, I cant find File Upload control. Is there any other options and how should I do it?I know there is a OpenFileControl but there is a problem on saving it / previewing it on a picture box.
This is my code for loading list of plugged in USB devices:
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click ListBox4.Items.Clear() For Each Drive As IO.DriveInfo In IO.DriveInfo.GetDrives
[code]....
I would like when a button (lets say buttontest) is pressed it will show all files of a CD (only MP3) into ListBox5, then when buttontest2 is pressed the files in ListBox 6 will be copied from the CD to the selected USB device?
there's an img src=blah on a web page that I am loading with a webbrowser control, and I want to alter it to say img src=blahblah instead ... What I've been doing so far is waiting for the document to complete, doing a .replace, then saving the file to the hard drive, and finally navigating to that local altered version.I was wondering if it's possible to skip the step of replacing and reloading the local page, and instead, just dynamically alter the original source code of the page AS it's loading the first time. Can this be done?
