Powerpoint Slideshow Does Not End When Saved?

Jan 16, 2009

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?

Powerpoint Slideshow Advance Slide Programatically?

Mar 23, 2010

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.

Build A Slideshow App That Will Display 6 Pictures At A Time From A Specified Folder?

Aug 31, 2009

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.

.net - Accurate Windows Timer - System.Timers.Timer() Is Limited To 15 Msec

Jan 15, 2009

I need an accurate timer to interface a Windows application to a piece of lab equipment.I used System.Timers.Timer() to create a timer that ticks every 10 msec, but this clock runs slow. For example 1000 ticks with an interval of 10 msec should take 10 wall-clock seconds, but it actually takes more like 20 wall-clock sec (on my PC). I am guessing this is because System.Timers.Timer() is an interval timer that is reset every time it elapses. Since it will always take some time between when the timer elapses and when it is reset (to another 10msec) the clock will run slow. This probably fine if the interval is large (seconds or minutes) but unacceptable for very short intervals.Is there a function on Windows that will trigger a procedure every time the system clock crosses a 10 msec (or whatever) boundary?

UPDATE: System.Timers.Timer() is extremely inaccurate for small intervals.I wrote a simple program that counted 10 seconds several ways:

Interval=1, Count=10000, Run time = 160 sec, msec per interval=16
Interval=10, Count=1000, Run time = 16 sec, msec per interval=15
Interval=100, Count=100, Run time = 11 sec, msec per interval=110
Interval=1000, Count=10, Run time = 10 sec, msec per interval=1000

It seems like System.Timers.Timer() cannot tick faster that about 15 msec, regardless of the interval setting.Note that none of these tests seemed to use any measurable CPU time, so the limit is not the CPU, just a .net limitation (bug?)For now I think I can live with an inaccurate timer that triggers a routine every 15 msec or so and the routine gets an accurate system time. Kinda strange, but...I also found a shareware product ZylTimer.NET that claims to be a much more accurate .net timer (resolution of 1-2 msec). This may be what I need. If there is one product there are likely others.

Asp.net - Local Static Variables In Timer.Tick Event (Stopping A Timer)

Jul 9, 2009

I have a timer on a page in ASP.NET.

After a certain period of time elapses, I want to disable the timer.

I want to put a static variable in the timers tick event that will track how many seconds have elapsed.

My question is, will this work?

If user X and Y are viewing the page will they both have separate local static variables?

What is the best method of shutting down an ASP.NET timer after a certain elapsed time?

Synchronize The Timer Event So That The Timer Executes From The Background Worker Thread?

Apr 23, 2009

I have a windows application that need to process som quite time consuming jobs. In my first try i did all processing under
the form thread. The result was bad response and update of the form due to the heavy jobs.To get around the problem with bad response from the form i created a new class "processing" where i put all the data processing. Then i instanciated a background worker where i in the "doWork" sub created a new instance of "processing".The "processing" class creates a timer from system.timer, and the timer drives the processing.On the Timer event Elapsed the timer starts a new thread from the thread pool.

My problem is now when i want to asynchronously close the background worker (with the corresponding function call what ever it is called ...) there is still a timer thread out there that causes exceptions for me.

1. How can i close my background worker and at the same time have the timer to be stopped?

2. Is there a way to synchronize the timer event so that the timer executes from the background worker thread?

3. Is there a better approach for me to adapt?

Create An Array Of Timer - Raise The Tick Event For A Particular Timer?

Jan 11, 2011

I want to create an array of timer in vb.net. My problem is that how will i raise the tick event for a particular timer, say mytimer(x).tick and inside the tick event there is also a button, say mybutton(x) which changes location every interval. for example:

public class blah
dim mybuttons(20) as button
dim mytimer(20) as timer
private sub form_load(....) handles me.load
for x as integer = 0 to 20

[Code]...

i dont know what to do next, all i want is to pass the button mybuttons(x) to mytimer(x) tick event, in which their index number are the same. i want to create one timer per button. how to do that? please help me and post example codes. i've researched the net but i cant understand passing variables, addhandlers, etc. i'm just new to programming object oriented.

.net - Systems.timer.timer Unwanted Multithreading?

Jul 14, 2011

I recently switched my code from using the windows.forms.timer to the systems.timer.timer and it has resulted in a multithreading error. I'm using the timer to trigger just one event so multithreading shouldn't be an issue. To give more detail I have implemented the timer at follows:
At the top of the class I have: Private Shared timr1sec As System.Timers.Timer

When the program loads (Private Sub Test_load):
timr1sec = New System.Timers.Timer(1000)
AddHandler timr1sec.Elapsed, AddressOf OnTimedEvent

In OnTimedEvent I call several subroutines, and write some data to the screen using a ListView object.VisualExpress throws the multithreading error on the last line of this code, which is in OnTimedEvent
