I am using VS 2010 on Win 7 32 bit.I am debugging a VB application (simple Windows form) by stepping through it with F8; however, for some unknown reason it sporadically runs at full speed after I press the F8 key. This can happen at any given location in code and sometimes not at all.

Not really asking for code, but I'm interested in knowing the basics of "thread performance".For example, you try to copy a bitmap in a pixel by pixel operation. (Is slow, but it is a nice example)

This is, of course, very buggy and causes a lot of violation errors etc. But that doesn't matter right now. How come the multi-threading way is so much faster than the regular routine? Is the processor not running on full speed with the first code, and is it working harder on the second?I find it weird to see this type of "threading performance increase", as if every single thread gets their own piece of processor speed allocated like it is a new process
i have an application that i need to speed-up, i think using Ngen will do this for me but i have no idea how to do it, is ngen something that run's when the user installs my applicartion, is this somthing i do before i create an installation program?
View 3 RepliesI have tried looking at "related" questions for answers to this but they don't seem to actually be related...Basically I have a VB.Net application with a catalogue,administration section (which can alter the catalogue, monitor page views etc etc) and other basic pages on the customer front end.When I compile and run the app on my local machine it seems to compile fairly quickly and run very fast. However when deployed on the server it seems to take forever and a day on the very first page load (no matter what page it is, how many stylesheets / JS files there are, how many images there are, how big the page markup is and so on). After this ALL the pages load really fast. My guess is this is due to having to load the code from scratch; after that, until it is recycled, the application runs perfectly fast. Does anyone have any idea how I could speed this part of the application up? I am afraid that some customers
View 1 RepliesMy application works fine.However, I am connecting to 5 DBF files and the queries are very slow.[If I copy the DBF files to the local hard drive everything runs fast enough. 30-40 seconds vs. 1-1.5 minutes]The DBF needs to stay on the network.I am hoping that using the index will speed things up enough.Can anyone tell me how or give me a code example on how to index on DBF files?

View 2 RepliesI'd like to create a simple application to determine the writing speed. In this application I want to view a line of text (may be more than one line) to the user to write it. And I want to select (higlight) the character the user pressed in my line and to move like a cursor to the next character (or to put underline under the current charater). How can I do that? and what is the object or component i must use to insert the text. Finally, if I want to make it multiple lines how to determine the enter key pressed by the user and how to move the cursor to the next line?
View 2 RepliesI'm asking this question here, in this forum, as I couldn't find MSDN Managed forum for Crystal Reports. And the previously asked questions are unanswered. I've developed an application using VB.NET and Crystal Reports in VS2008. The report generated gets printed correctly on modern laser or inkjet printers. However, the entire formatting gets affected when I print these reports on dot matrix printer. Apart from that. the print speed is very slow. I tried exporting the report to PDF, XLS, DOC and other formats - but no solution. There was Export to Text function, which is not working in Crystal Reports now.

View 6 RepliesLately our network is having some speed issues at certain times of day, so what I'd like to do is make a little app that will test the network speed at certain intervals, like once an hour between certain servers etc and then write the results to a text file. Is VB 2008 cable of doing something like this? I thought of maybe copying a 500mb file from 1 place to another and somehow record the average transfer rate of that file, but I am not exactly sure about how to record the transfer speed.

We are four in a team using a data entry application created using VB and MS Access as backend DB. The application is installed on all our PCs, but uses my PC as server. We enter data at same time. The application has been slow since we started using it. We were advised to increase the internet bandwidth, which we doubled, but the application is still slow. What can be done to increase the speed of the application to make work move faster?

View 2 RepliesI have two timers in my application. One that updates some text label every 100 ms, and another one which makes the text scroll to the left. Both timers are working fine, however,if Timer2 is enabled i get some problems while playing fullscreen video in VLC. Usually the mouse dissapears when running full screen and leaving the mouse, but if my program is running (and therefore Timer2 is enabled) the mouse wont dissapear. If i go disable Timer2 theres no problems.. I just dont understand why it is only Timer2 that does this and why timer one doesn't affect VLC? Timer1 and Timer2's code is below
vb.net
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

In addition the working existing class makes the same call with no error and the IDE allows normal stepping into it
