I wrote an app in Visual Studio and is about 20k+ lines, but I don't know why it takes so long to start up. I have a splash screen just to test it to see if the program is working, and it is, but I have to wait for so long for the app to actually get to the start up form. A splash screen for this app isn't ideal, but was only using a splash screen for test purposes.
View 1 RepliesI am creating a WPF Application that uses Fluent library.
On my computer with Windows 7, 2GB RAM and AMD Triple Core processor, after double clicking on the program icon, The Splash image shows after about 1-2 seconds.
But on my brother's old computer with Windows XP, 512MB RAM and Intel Celeron 2.0 GHz Processor (Single core), after double clicking on the program icon, First, a process called PresentationFontCache.exe runs and it uses almost 100% of CPU for some seconds. And Total time is needed for displaying the initial Splash image is almost 30 seconds (or more).
I don't want that some users have to wait 30 seconds for displaying splash image and about 7-8 seconds for loading application. (my application load process takes 7-8 seconds)
I have custom asynchronous WebRequest class that I am testing to find out how fast the request will be cancelled and found some odd results, that starting 6 WebRequests with TPL and cancelling them right away takes 25 sec, but when I used just regular background threads it took only 5 sec.
Update: Running them without cancelling takes with Task.Start 9 sec and Thread.Start 3 sec accordingly.

I have a client application that connects to a WCF service, i get the file size from the server as a long value then i convert it at the client to a string so it appears like ex:52.21 MB the application gets too many files sizes every time user changes the directory pathso the question is :should i convert the values to a string format from WCF service app then return it to the client as a string format or should i just return the size as a long value and let the client to convert it to a string format in other way which value take more bytes in the memory:

I'm using the following code to fetch a mac address
Try
Dim cls As New ManagementClass("\" & IP & "
ootcimv2", "Win32_NetworkAdapter", New ObjectGetOptions(Nothing, TimeSpan.MaxValue, False))
Dim col As Object
[Code]...
It is working as expected. My problem is that it seems to wait far too long for devices which do not respond, and when the output of GotMac is "The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)" How do I shorten the wait time for these types of events?
I've been using VB for exactly a week today and for that past 4 hours I've been pulling my hair out! My problem is that our software can only run on one PC on a site, if two instances are running they cause issues. So instead of checking each PC individually I created a program with VB to do this (and other tasks) for me. The problem with the network search is that if I cannot access a remote PC (usually access is denied) then it hangs for a long time before moving on to the next. Can I introduce a timeout feature where the program tries to access the c drive but if it does this for more than 5 seconds and gets nowhere then it moves on? [code]'testcpath' is \pcnamec$ and the other two paths look for the software I'd need to remove if found. So basically, if I have access to every c drive it works fine and completes within a few minutes. If I don't have access to even a small amount then it takes an absolute age.

How to terminate function/code (not entire page) when it takes some time, for example, more than 1 sec?[code]...
I found the command "Server.ScriptTimeou", but it stops the entire page instead of one command.
I'm trying to time how long an operation takes in Visual Basic (VS 2008) but its not working. the code I have is as follows:
[code]...
this is in an OnClick event, so what happens is that the user can click a menu item, and it goes and sends any changes it has to a database, and pulls down any new changes to a local data cache. This operation takes time, depending on how many changes are on the server and how many are cached locally. I've thought about making this a background task, so it doesn't draw away from the main app while it's running, but before doing that, I'd like to get an idea how long the operation takes. Since I can't exactly do a progress bar, I figured using the stopwatch would tell me how many ticks/milliseconds would occur between click, and when the "total synced" message comes up, but every time i run it and do an update the message always shows 0 ticks/ms. I don't think it's accounting for the delay, just from start to finish. Is there any way to make it so it detects a message popping up and times off that?
Here's the (Timer1's interval is set to "1" in the designer, and it is set to "Enabled" in the designer as well.)
vb.net
Public timeElapsed As Int32Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
timeElapsed = 0
Timer1.Start()
[Code]...
The issue is, timeElapsed always comes back as equaling 0, so fileCopySpeed always equals infinity. Also note that test.dat is a 100MB file. There's no way it's getting copied in under 1 millisecond!
I've written a small application that keeps track of my thesis notes and essentially I have a few textboxes for keywords, ideas and notes. When I type in the textboxes and hit my update button it works fine...when I cut and paste from a text editor into the textboxes and then hit my update button it takes way to long to return control to the form. Is there something I need to do to text that is copied and pasted into a text box before I send it to the database?

I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?
View 2 RepliesEvery time I make even a very small change to a form in the form designer, when I try to move off the screen to write code, or run the application, VS 2010 takes up to 1 hour to figure out what the small change was, process it and then let me continue. Is there some fix that I am missing to make VS 2010 be able to handle small changes to the form_designer, or is this just the way it is?

View 2 RepliesI've a solution with 15 projects (14 class libraries and one web application). Each class library has corresponding test project (i.e. if I have MyApp.Services project there exists MyApp.Services.Tests -- using NUnit). Everything is written in VB.NET. The problem is that when VS tries to compile any of *.Tests project it stops responding (the bigger the project the longer the period without reposnse). I don't know where to start looking for an issue. I'll add that I've R# 4.5 installed.
UPDATE 1:Is there any way to benchmark a build in visual studio? To get build times for every project?
UPDATE 2:It seems that there is no difference after disabling R#.

View 3 RepliesI'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.

I am working with the my.application partial class and I was trying to launch some events off of the networkavailabilitychanged event and what I have noticed is that it takes 9-10 seconds to fire that event if I disable wi-fi and pull the LAN cable on my development machine. What I would like to do is significantly shorten this duration. Something like 100ms would be great. If no, what else can I poke for a network status that will handle this response time?
