You should minimized and focus your question, although to give an example of what you need because few persons will try to understand what you need

As you've discovered, a PictureBox only shows one picture at a time. If you want to show multiple pictures, then you need to either have an collection of PictureBoxes, or draw the images onto the PictureBox's Image manually. Look up the System.Drawing namespace for details, or search Google

And the reality

And the act

I am not sure about what you are asking for, but following snippet code demonstrating how to work with PictureBox and array:

Public Class Form1
Private arrImages() As String
Const PicNumber As Integer = 3

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ReDim arrImages(PicNumber - 1)

arrImages(0) = "C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Blue hills.jpg" '"Path1"
arrImages(1) = "C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Sunset.jpg" '"Path2"
arrImages(2) = "C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures\Water lilies.jpg" '"Path3"

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Static ind As Integer

ind = ind Mod (PicNumber)

PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage
PictureBox1.Image = Image.FromFile(arrImages(ind))

ind += 1
End Sub

End Class

Instead of Button1, you can put a timer that will display your pictures like presentation (you may have to add Application.Doevents in the timer event)

Declare array with 'Image' type
dim Picarray (1) as Image
Picarray(0) = System.Drawing.Image.Fromfile(ImagePath)
Picarray(1) = System.Drawing.Image.Fromfile(ImagePath)

You know the questions you are asking are very simple for beeing found in google. You only have to work a little and enter in google something like that: "load images from folder to array + vb.net" OR "updload inages from folder" etc...

The snippet code should be something like that: (I didn't compile or run it, but this is the concept)

private sub f()
dim fld as new IO.directoryinfo(YourFolderPath)
dim arrImages() as string 'or images as you need
dim ind as integer =0

for each fil as IO.fileInfo in fld.getFiles("*.your extension")
redim preserve arrImages(ind)
arrImages(ind)=... 'like the first answer I gave you
ind+=1
next

fld=nothing
end sub

Your posted code helped me also but i have one more query -How to take images dynamically means i dont know images name.If i replace all images from same folder then what to do??
So i want code for that in which image name is not fix....

If I understood your question, you do not have to know image name. When you loop into the folder that contains all the images, the name property of the fil (as IO.FIleInfo) variable handle the name of the image file.

Option Explicit On
Imports System.IO

Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim fld As New DirectoryInfo("C:\MyPictures\")
Dim arrImages() As String, ind As Integer = 0

For Each fil As FileInfo In fld.GetFiles("*.jpg")
ReDim Preserve arrImages(ind)

arrImages(ind) = fil.FullName
ind += 1
Next
End Sub
End Class

hope it helps you

Hi,
Am a student studying information technology and try to develop an online hotel reservation system in visual basic 6.0 as my personal project to improve on my programming skills. I tried to code part of the customer data page and now i,ve failed to proceed. I welcome any kind of help and even on how the system is supposed to be laid.
Confused | :confused:

Any help will be treated with high respect.

Thanks in advance.

STOP You are absolutely WASTING your time, download a copy of VB.Net express off the internet - it is FREE, no cost, no licence issue, nothing. Microsoft WANT you to have a copy

here is a link [^]

Now go out and buy, yes spend a little money, a book on VB.net. Spend some time getting to know VB.Net and then come back when you have a little knowledge and we'll help where we can.

I suggest you also get a book on database design as well, you will need it.

Don't.
vb6 is ancient, it's no good and never was, it's no longer supported.

Like Mycroft Holmes said use .NET

I find it very hard to believe that vb6 is still being given at schools.
If so please tell me what school so I can personally go set them right.

Online indicates this is a web application. So better forum might have been the ASP.NET forum.

I've been interviewing graduates this week. Quite a few have VB6 classes on their CV - it is quite disheartening.

Despite that fact, it sold well. Lots of small "software" shops that sold VB6-based applications, lots of brownfields left Smile | :)

It is in the countries where the hardware is somewhat older - one has to use legacy-software. I can't imagine Vista on a 486.

What is a "customer data page"?

May I suggest that you start by writing out use cases (short stories of how various users will interact with the system. A customer wants to do X, the hotel receptionist needs to check in a customer, the hotel receptionist needs to check out a customer, the customer wants a room for 4 people, etc.)
