I made two applications the first one calls the other. But the other application takes time to load. Even on a fast Pc. So i was thinking of adding a loading form to it. For example when the other application is done loading the loading form goes away.

in my program i have a timer, and every 5 sec (for example) i send a string by serial.i have to read every key pressed between each 5 sec and send a number that tells me what i am sending.what I've done is to send 1 as long as up key is pressed and send 8 as long as left key is pressed and send 9 as long as both are pressed.when i run my program, the first time i press up and left at the same time and i keep them pressed, the serial send me the first time 9 and then ignores the up key and send me 8 always.and sometimes send me 9 and after that always send me 1 and ignores the left key..the point is that vb ignores the first button i press even if i keep pressing it..what should i do to make vb.net takes two arrows keys at the same time?

I upgraded vb6 project to vb.net. Conversion of 3 user controls from vb6 to vb.net have done. Some converted code contains code like:
VB6.TwipsToPixelsY(LedHeight)
MyBase.Width = VB6.TwipsToPixelsX(VB6.PixelsToTwipsX(LedCol(0).Width) + 15)
The converted project takes too much time to load than previous vb6 project. What manual changes to the code should be done or is there any other option. Is it due to vb6 to vb.net conversion.
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?
I ran into a problem where the listbox is taking awfully long time to show up. This is not the same in java(It took very very less time - one second max). So, is there any remedy to this??, any other form control??, or some other way?? imports System.Threading imports System.Windows.Forms

Basically, It is a program that allows you to automatically click things.
Here is the

What I wanted to do was make an option to have variations in tick time. I want to put in a check box, and if it is checked then there will be 10 "variations" in click time, ranging from 1 second too soon, to 1 second late.
Although I have no errors in my code; however, I am not able to find the time it required to do the shell sortwhat am I missing in these codes?

i'm making a utility in which i'm loading 100,000 records again and again, problem is that it takes much time to load records in datagridview every time.
i've used data set and data reader both but same result. if i use paging then there's will be a problem of search a record on keyup event.
I am using the below code to get the local Administrator members, but this code takes about 6-7 seconds to execute. More precisely the "GetObject" takes that long.Is there another way to get the same information but faster?Also, where can I find what other properties the objects holds ? (To see what other useful information I can get)[code]
View 1 RepliesWhenever I publish my app, or when I run the exe from teh debug folder it takes a couple of seconds before the splash screen shows.However, when I run it from within VB (by pressing the "play" button) the splash screen shows immediately.
What could be the cause of this?
I have the below code. What happens if the Upload method takes more than one minute for completion? Does the timer kick off another call to the Upload method immediately after one minute is over or Does it wait until the method finishes executing? I am implementing this as a windows service.

Dim tmr As Timer = New Timer(New TimerCallback(AddressOf Upload), Nothing, 1000, 60000)

I have 4k records in access database. And one of the field value contains ~100 lines each so and one other field has ~25 lines. So total database size reaches ~30MB and it takes lot of time 15-20 seconds to load the database in vb.net using odbc [URL]..and updating of any other small fields also takes time due to database being large
So as an alternative I used rtf file (txt files were not preserving all the newline characters). So these file are around 5-10kb only. But for 4k records and 2 fields I have now 8k files. And copying of these 8k rtf files is taking huge time for 5MB transfer it takes an hour or so.So is there any other alternative for storage of this data. So that it will be portable and easily loaded/accessed/updated from vb.net?

View 3 RepliesI was currently writting a Cyber Cafe for the client side which start up with a form that maximize and block all the client control like shortcut key and other security. It's fine to work in my pc and it take only about 5 second to startup the application and lock the client. But when i run the application in a pc that installed with games, it took about 40 second to run my apllication. I notice in task manager panel, the process need to read the whole application before it could load my first form. Is there any idea i can speed up my loading time? I have try to set the process priority to "real time" and startup using batch files, but it still need 30 second to load my first form.

View 1 RepliesI like to make an console application to measure the time it takes to fully load a web page, what's the best approach to do that? The purpose of this small app is to monitor some pages in a website, in a predetermined interval, in order to be able to know beforehand if something is going wrong with the webserver or the database server. It would be nice to be able to measure the time it takes to fully load the the page (images, css, javascript, etc). I have some code but I is not measuring the fully page.

View 3 RepliesI have a question. I am creating a VB .NET application that opens Visio to do some stuff there. Visio runs a splash screen on startup and the only way to stop the splash screen from loading is to use code like:
"C:Program FilesMicrosoft OfficeVisio10Visio.exe" /nologo
"C:Program FilesMicrosoft OfficeVisio11Visio.exe" /nologo
"C:Program FilesMicrosoft OfficeVisio12Visio.exe" /nologo
For each Visio versions in the command line (but I am not using the command line).
The problem I am having is that I can't run this code from my vb .net application, because my application uses the following code to load Visio:
Dim vsoApplication As Application
vsoApplication = New Visio.Application()
vsoApplication.Visible = False
And I do not know how to call the "/nologo" feature on loading time from my code to skip the Visio splash screen.
I have a window application develpoed in vs 2008, framework 3.5, in which i have put a button.. Now where i click that button the other text boxes are filled up with the data from database thru web service.. what i want is while all text boxes are being filled i want to show an animated loading gif image till data loading is completed in all the text boxes.. i have tried to use image picture box but while data is loading gif image is displyes but in static mode.. cant see animation... i think this is because data loading and animation both are done thru one UI thread..

A couple days, I figured up a working program and it was def. faster than what we needed. Now, adding a couple more loops, the program barely uses any memory, but the cpu used spikes up to 90+ and just letting it sit doesn't help.I tried taking out the couple loops I put in, but it does not revert back to being fast. It's nothing big, but since dealing with 1000+ excel files a day, I'd rather not do that by hand.
how many infinite loops vb.net can support without dragging down the system? I know, infinite loops are poor design, but it works.
I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
