I have just created a picture viewer that can open the picture and show it in the picture box on my form, but I want the program to open more than one file as normal programs do. How do I make this happen? I want it to show the next button on the form especially when there is more than one picture on the directory I am currently opening the picture from.
The program opens only one picture and I have to open new picture again and again instead of using the next arrow.
Code sample:
Public Class pictureViewer
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click

I am a complete newbie when it comes to programing so i downloaded Visual Basic Express yesterday. I followed the tutorial here to create a picture box. [URL] Now i am going through and making some changes. Is there anyway to make a code so that there can be a next and back button?
I have followed a tutorial on how to make a Picture viewer. I have a next and back button that read off a counter. I have a couple of questions on this.
1. If there is just one picture in a folder and you hit the next or back button, the application crashes, is there a way to disable these buttons if there is only one?
2. Every time I open a new folder, the contents get added onto the list to go through, is there a way to overwrite the old files so only the new folder shows?
I have managed to build the basic Picture Viewer Program. Now Remember the program I am working on is for a Digital Picture Frame there is NO wirless network adapter on the old pc and there is no keyboard going to be attached to the laptop so the program must launch its self (ill put a short Cut in the windows startup folder). I got a picture box that excepts the picture file it covers the whole form! (when there is a picture in the picturebox1 it fits the screen) My form one covers the entire screen (I set the windows border from scalable to none). I need to make my program scan for picture files on different drives and then every 30 seconds or so choose a random picture from the usb drive and display it Posted below is my code:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click OpenFileDialog1.ShowDialog() PictureBox1.ImageLocation = OpenFileDialog1.FileName ' want to remove this feature so the user cant see this [Code] .....

I am making a Digital Picture frame out of my old dell laptop and I would like to make the program for it. How to have it play a random image every 30 seconds or so...

I recently upgraded to VB 2010 Express (from 2008), and I have a problem using the debugger. When I move the mouse pointer over an array variable, I only can get the value for the current index, and not values for all indices, as I did in 2008. For example, if I move the pointer to classSize(i), I see the value for the current value of index i, but I do not see the plus sign which would display a drop-down list showing values of all elements in the array.
I checked for options (Tools > Options > Debugging > General), but did not see an option related to DataTips.

I am trying to get OpenSSL.net to 1) create a key pair to use for CA signing and 2) create and sign certificates using this CA. I have managed to create an RSA/SHA1 X509CertificateAuthority, and have created a X509Request and keys, but I am running into problems actually signing the request.

I'm building three web applications in .NET that will all share a users database and login information. Lets pretend that application 1 is the "parent" application and applications "A" and "B" are the "child" applications. All users have to be logged into application 1 to have access to applications A and B.
Authorization, Authentication, and MachineKey sections of all web configs are present and work correctly.
I have the correct web.config settings in all applications to achieve Single Sign On except one problem remains: what do I put in the "loginUrl" attribute of the forms tag in Applications A and B.
Assume that the url for the login to application 1 is [URL] How can I get applications A and B to send the user back to application 1 for authentication using only settings in web.config?

I would like to know how I would separate the $ from number. I am reading data from a text file. the last column has a contain $12.00. I am able to split the five columns into an array. But also want to be able to remove the dollar sign.
I am trimming some strings but I am unable to do anything about the strings containing plus signs. For example if I have this string with a telephone number
Dim str As String = "+46765124246" And try str.replace("+46", "0") Nothing changes in the string.
