My 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 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 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.

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.

Say you press and hold down a letter on your keyboard. The first letter gets added, there is a delay and then it repeats quickly on screen. Is it possible to skip this delay and go straight to the repeating part? I realize this might not be a visual basic question as much as a windows question, but if there is some way of toggleing it through my program, or using a workaround, i would like to hear the alternatives ^^ Setting the windows setting to fastest still has a small delay and others users would still experience it on other computers.
View 1 Repliesi am trying to complete a project. My task is to read large TXT files (300 files, 2.2 GB in total) read the customers inside, perform some data calculation and write each customer data to a separate txt file.
I made a code in VB6, it runs fine, however it takes 8 days to run on a quadcore processor, utilizing 20-30% of the CPU. Now I upgraded the code and am running on VB.NET 2008, the latest version. The speed still remains the same, and the CPU usage is also about the same.
Anyway I can make this process faster. I have a quadcore PC with 8GB of ram, possible to maybe make VB utilize all the CPU say 100%? so it executes atleast 2 to 3 times faster.

View 6 RepliesI'm working on a CMS web app (aren't we all) and wondering if it's better to store the content of web pages as files on disk rather than text fields in MS MSQL.

Does anyone know if retrieving the contents of a file on disk is overall faster than reading it from a large database field?

For some reason, .NET applications that I've written seem to have issues if they're launched when Windows starts (by being in the Startup folder for instance). An application that can finish in 3/10 of a second if one launches it normally may seriously take 45-90 seconds to finish if it was launched when Windows loads. Even if I just manually wait 30 seconds after login and launch the program, it'll complete virtually instantly while a copy launched at startup is still struggling along, so it isn't just that Windows is still loading...this continues AFTER that finishes and all HDD activity stops.Writing something to disk using an IO.anything goes at about 20KB/s during this event.
