Array For Slideshow Button?
May 23, 2010
I have a form that i call like so:
call frmSlideShow.showWhat("1,4,8,9,11,22")
Each of the numbers represents a different image slide (slide1.png, slide4.png, etc..). The problem i am having is trying to create a "previous" and "next" button to flip through them all. Trying to figure out what number the user is on and going from there and seeing what numbers are still left from the list above that was sent, etc.
here is the code..
Public Sub showWhat(ByVal theNumbers As String)
Dim theNums As String() = theNumbers.Split(New Char() {","c})
Dim theCurNum As String
[Code]....

I have a little problem with an application I am developing. My application is supposed to save a powerpoint slideshow, which I have finish coding. The code is as follows,
Dim dal As New CreateDAL
Dim bll As New createBLL
Dim searchQuery As String
[Code]......
However, upon click the button which calls these codes, the powerpoint slideshow that is saved does not end when it is in slideshow mode. For eg, there is 5 slides, after reaching the 5th slide, it returns back to the 1st slide and repeats over and over again. I'll have to press the ESC key to end the slide show. Is there anyway to prevent this? Perhaps I'm missing a statement to make the ending slide the last side?

I have written a VB.net 2010 Powerpoint addin that needs to be able to advance the slide via a button on it's main form when running the presentation. The functionality I require is exactly as if you press the space bar while focus is on the slide show window.
I have tried-PowerPointApp.ActivePresentation.SlideShowWindow.View.Next
But this does not work in excatly the same way, namely when working with several animation sequences on the same slide.I am looking into using the API - FindWindow & SendMessage but I do not fully understand the steps to get this to work, or even if it can. Or is there another way?
I am using Visual Studio 2010 RC with Powerpoint 2010 Developer Beta.

I am trying to build a slideshow app that will display 6 pictures at a time from a specified folder. I put 6 pictureboxes in a TableLayoutPanel and have a timer control call the Ahead1 subroutine to load a new picture into the last box after all of the other pictures "move up one box".The problem is that every the timer calls the Ahead1, the program uses about 30MB of RAM and the program eventually ends with an OutOfMemory Error. (Choosing the Picture Folder - only called once)
Private Sub ChooseDirectoryToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ChooseDirectoryToolStripMenuItem.Click
FolderBrowserDialog1.ShowDialog()

I have a modified button control with a string array in it. I am having trouble sending the string array to the form with the modified button on it. Anyone know what i can do? The form uses a arrayList to hold the buttons since they are made at runtime.

I have a button array that I filled up. Here is the code I used to do that.
Public buttons(29) As Button
For i = 0 To 29
buttons(i) = CType(Me.Controls("Button" & i), Button)
i += 1
Next i
Here is some code that I used (it is extremely inefficient):
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click, Button2.Click, Button3.Click, Button4.Click, Button5.Click, Button6.Click, Button7.Click, Button8.Click, Button9.Click, Button10.Click, Button11.Click, Button12.Click, Button13.Click, Button14.Click,

I have a project where I am to enter a name and a test mark into two separate text boxes and then select the button to store the information into the arrays, one array for names and another for marks and then you can click the calculate adverage mark button and a label should calculate the adverage mark but I cannot get the marks to be added and then divided by the number of entered marks. Such as: you enter in a name and a mark of 75, and then another name and a mark of 50 and then another final name and mark of 25. I have been trying to get it to add up the marks of 75, 50, 25 and then divide it by 3 the number of marks in the array, but it wont and I cant get it to add the marks as a integer no matter what I seem to do.
Here is my code:
Public Class frmAdverageTestMarkCalculator
Dim ClosingMsg As String
Dim Closingtitle As String
Dim SureAboutClosing As MsgBoxStyle
Dim Closingresponse As MsgBoxResult

I have created 3 arrays of buttons for a form which manipulates the value in a combo box or 2 by the name of the button ( buttons named 2 through to about 70 )
This works great but the problem is, now that the buttons are in, I want to be able to change the color of the buttons when another button is clicked
ie. The first bunch of buttons is a list of locations all with unique text.the second bunch of buttons is events that happen, sign on, sign off, beach open and beach closed.
What i want to be able to do is change the color of the button clicked "before" i click sign on, sign off, beach open or beach closed.
I do not know how to reference these buttons in my code as for starters, they are numbers, which is a big no no apparently. Also, even if i change the name from just a number to something like cmdBeach(i) when creating them, i still can't refer back to cmdBeach5 in my code as the button doesn't exist yet

I have an global array of points that i want to plot in VB. say X and Y points, and typically they have values of +/-12000. Now I've not done graphics work for a long time and when I did, I used OpenGL with C. Now I need a GUI i'm using VB 2008. Firstly, what's the best method of rendering the array of points? should I use some port of OpenGL? GDI? or what?
Secondly, can I simply print to perhaps a Panel on hit of a button? Thirdly, do I have to place any line drwing code in an "OnPaint" event handler? Finally (for now) if my array represents points in a space much larger than the painting surface, how would I scale and scroll the final image within the the proposed Panel? I look forward to your advice.

My project is basically a addition test for 5 to 9 year old children. On my form I have a button which when clicked, it inputs a number from 1 to 10,( which is chosen by the user via an combo box drop down), into ten text boxes. I have built and array and used a, for loop for this and it works fine. [code] My problem is I need to create another array connected to the same button to genarate 10 random numbers. Which will allow the user to add the two numbers together.My problem is that visual basic wont let me add a second array to the same button?

In my example, i use a class array to which I assign values looping through textboxes in my form. Using the button Store (btnStore) the values are perfectly assigned to the array (i use an msgbox to check).The problem is that when i created another button (btnTest) to test if these values can be read outside the btnstore code, I get an error (NullReferenceException unhandled) which informs me to use the new keyword (cannot be used with arrays).I suppose the same applies when trying to access the array from another form. The question is how can i assign the values to the array "forever" and be accessed from "everywhere" in my program ?(tried public, friend, redim preserve the array with no luck).

I am working on an inventory managment project for a lumber mill. I am currently writing a piece of software to be used on the sorting section of the mill. The problem I am having is when a stick of lumber needs to be cut down in lengt. My current setup has a combo box that is populated with lengths of lumber that we might have (2' - 60'), a "Add" button and a data control (homemade solution with lots of labels, and panels).
The user will scan a tag into the system, and the system pulls up the info from the db. If the piece need to be cut, the user will select the length of the cut, and click the add button. The system will then populate the first line of the data control with the info from the cut (previous piece info, and new length). It also populates a pieceObject struct. This happens for any additional cut that might happen.
The problem I am having is that everytime I press the "Add" button, the length variable will update every length in the piece array.
Here is a section of the code I am dealing with.
piece is a lumberPiece, and pieceAry is a array of 15 lumberPieces
Each time the add button is pressed, the current data is stored into the array, and then the pieceNum is incremented.
