I have the following code. My program loads 20 pictures in one panel and each pictures has for the moment like 500 Kb, but in the future they shall have like 2~6 Mb.When I use this part of code, my program that uses only 6 Mb of memory, but jumpes at 202 Mb when pics are loaded. I need a method to resize or make them thumbnail or something to reduce the memory.I don't know for the moment how to use the System.Threading, but I want to know if it shall help my program, if not, then help me replace parts of my code.Private Sub PanelPictures(ByVal picsoriz As Integer) ' picoriz represents how many pictures should the panel have on each row (it's set at 5 pictures per line/row) [code]
View 4 RepliesI'm developing an adding for office powerpoint application.I'm trying to display a description of the object(Customized object) currently dropped on the powerpoint slide in design mode(Design mode of the powerpoint).When i click on my addin the related object description will be displayed on a tabbed window as the first tabpage.
There is a button on the tab page, and when i click on it i need the description to get copied to windows clipboard.I tried this using clipboardclass it throws the following exception, System.Threading.ThreadstateException {"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it."}
Code for clipboard:
Clipboard.Clear()
Clipboard.SetText(lblObjectID.Text)
I searched the net for a solution and got couple of answers like, Put [STAThread] in the main function Thread.CurrentThread.SetApartmentState(ApartmentState.STA) Immediately before your call to SetDataObject.
But I'm not sure where to put the 1st one and the 2nd option didn't work.
I have used system.timers.timer to watch several folders and move files in my windows service. But the timer event stops now and then. I have read that it is better to use system.threading.timer in services.This is my system.timers.timer
Private Timer As New System.Timers.Timer
AddHandler Timer.Elapsed, New System.Timers.ElapsedEventHandler(AddressOf Me.Timer_Elapsed)
Timer.Interval = 4000
Timer.Start()
[code]....
How do this code look like in system.threading.timer?How do i start and stop the timer using threading? That is very important because i stop the timer when it comes to the elapsed event and when the code har run it starts the timer again!
I would like to discover the system.threading namespace. I look in the References -> Add -> .Net(tab) to add a reference to my project, but it is not listed in the .net references. I work with framework 3.5 service pack 1. How can I install this namespace?
View 4 RepliesI'm just looking for other people's thoughts and opinions on the way I have done something.I have a console application which needs to connect to various computers and reset the local admin password on each one. I got it all working but then decided that as there are a lot of PCs, it would be a good idea to use the thread pool to do a few at the same time.The problem is, I need this program to be run without any human interaction - so I cant just use ThreadPool.QueueUserWorkItem and pass it all of the computers to connect to, because then the program would exit after it had called QueueUserWorkItem for each one because there is nothing left for it to do. I cant stick a Console.ReadLine in there because like I said, it needs to be run automatically without anyone typing anything.

The error notification includes the name of the form, the exception error details, the event name and the screenshot of the software during that particular instant.

I have used timers in .Net for a long time now an never had this problem.Start timer to fire every 10 seconds that reads an object and updates the UI using a delegate.This works great until the form is minimized several times, then the timer thread seems to vanish.Anyone come across this before?
Obviously I can roll my own using a thread directly and sleeping it, however this seems like reinventing the wheel when a threading timer class exists already.

This works great but I can't open my app anymore when it's sleeping and it uses about 25% of my CPU. I guess there must be a better way to do this.

This code is going to work on a ProgressBar while typing and the value of the progress bar change while typing. The progress bar jumps to the new value and I want it to move. So I thought about puting it in a "For ... Loop" but the whole form freezes.

I'm using windows server 2008 & IIS 7.0 to deploy the my vb.net 3.5 application. I'm successfully able to run the URL on my server.Same URL having IP address & port number configured is not working on client system.
It is showing IE default error message as "page cannot display"
Dim wc As New System.Net.WebClientGamerTag.Replace(" ", "+")wc.Credentials = New System.Net.NetworkCredential(Email, Password, "http://live.xbox.com/en-US/profile/profile.aspx?GamerTag=" & GamerTag)Dim fx As New System.IO.StreamReader(wc.OpenRead("http://live.xbox.com/en-US/profile/profile.aspx?GamerTag=Dark Slipstream" & GamerTag))Dim str As String = fx.ReadToEndfx.Close()
The above code will open a webclient, set the credentials (possible error?), create a stream of the entire page, and then load it into a string (str).I then scan through and look for what is needed (Gamerscore, Motto, Bio, etc)-in this case.This doesn't work however, it doesn't sign in.
I have written methods to override the LoadPageStateFromPersistenceMedium and SavePageStateToPersistenceMedium methods. now the problem is that i am using a masterpage, so how do i maintain using my masterpage and still inherit from System.Web.UI.Page?
