View 1 RepliesOK, I've been searching for hours trying to find the best way to fill a listview from a comma delimited file but have come up empty handed so far. Currently I am using code I found on the NET, which works, but it is EXTREMELY slow. As a test, I created a file with 5,000 rows, and 10 columns. The column layout is as follows:123,NAME,NAME,NAME,NAME,0.00,NAME,YEAR,NAME,1
Dim ofd As New StreamReader(".dataCardData.bct")
Try
Using reader As New Microsoft.VisualBasic.FileIO.TextFieldParser(".dataCardData.bct")
reader.TextFieldType = FileIO.FieldType.Delimited
reader.SetDelimiters(",")

The code I am currently using appears to be loading the file and somewhat simultaneously filling the listview at the same time. I feel that I should load the entire file into an array or arraylist and the send the array or arraylist to the listview. However, if this is the best way to do it, I have not been able to find any examples of how to do this.
I read that by using queries instead of SQL, the form can load faster, however, I have this code that has categories and sub-categories how can I shorten this code to have the form load fastr?

For a touchscreen oriented application, i have an onscreen keyboard that can operated by both the hardware keyboard, or via touchscreen/mouse. The user needs this keyboard a lot, but. Because it has so much buttons, it loads really slow and takes about a second to finally display.
My Onscreen keyboard is of type dialog, and its background is set to the transparency key. Once the form is there it works really well. the problem is the 1 second loading time, this can be pretty frustrating when you need to edit like 20 things. Is there any way to preload the keyboard dialog and make it popup instantly?

View 6 RepliesI have a few subs that run under Webbrowser1.document completed section of my app I know the code words because I tried it out using a new project and tied the code to a button and it works great. After stepping into my code during run time it appears that the app is trying to call my sub before the next page appears. What would be the way to place a pause on the Thread so that the web page can catch up before running the next sub?

View 7 RepliesI have a very urgent project due for Monday and I am trying to implement a very simple Windows Application for viewing files.
One of the requirements is to store the history of images accessed and provide a navigation tool for those images logged into the history.
I have been successful in logging/saving the full system absolute path to a text file. Now it is to be able to navigate through the lines.
I figured I could do this by first counting up the amount of lines in the text file after a new image has been loaded to the display and added to the text file[history] and
Then using the count on the history file of total files to either decrease or increase the number as appropriate to load into the image file the previously written absolute file paths as the new images.
I am writing in Visual Basic using VB 2008 express edition and I can't seem to figure out how to count the lines in the text file and sub sequentially manipulate the line being read to display the image.

I'm working on creating a very simple dice game for class (not for gambling purposes). The users has already entered their total amount of money, and are are able to wager for every round.

I want to pre-load a number of images from the web, so that I can display them in a form, and scroll through them without delay. It can be a large number, but i only need to pre-load perhaps 20, and then remove/add in advance, as I scroll through. The images will typically be .GIF or .PNG, of quite small size, <50kb. The link for any single image will look something like this: [URL]..and I will keep a list of all the links I need to access.
What "type" shall I use to store these images? And how do I make web requests to put the data into this type? I guess it will be more convenient to keep this as in-code list of some memorystream type (?) instead of saving them to disk and having to deal with file names and stuff..? Also, what type of control shall I use to display such images? Do I use a PictureBox?And if a memorystream is indeed the best choice, how do I make this show in the picturebox?

I am not a total newbie to Visual Basic. However, the last time I used it was back in the days of DOS and Windows 3.11. Now I am using VS10 on a Windows Vista machine and it so different, I feel like a total newbie.
I am working on a project that I wish to load RTF files into a RichTextBox and an accompanying image into a PictureBox at runtime. I want this to happen when the user clicks a Menu Choice.[code]....
The idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]

View 3 RepliesThe app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
