VB 6 To .net - Converted Project Takes Too Much Time To Load
Nov 22, 2011
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 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 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.

Whenever 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 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?

I am using 8 different vb projects in one solution, beside this I am also using one 3rd party control ion all the projects, while compiling the application it takes around 5 minutes to build the project, While building the application I have observe that it uses lc.exe file which is used for "Reads text files that contain licensing information and produces a .licenses file that can be embedded in a common language run time executable." at this point it takes too much time.

I used .NET Framework 1.1 in C/S project before. Now I have updated the project to use .NET Framework 3.5 without modifying source code, but I have found that : the Remoted DateTime values can not be converted to the equivalent local time of a remote computer that is in a different time zone. In .NET Framework 1.1, the DateTime values can be converted automatically.

Ok, this might be something stupid that im not doing right, but here is my problem. Im moving from my 1st form, a small window, into my second form, that is full screen, but it takes like 4-5 seconds to load the full form. It sucks because during this 4-5 second load time, parts of the form at transparent and it just look bad. I think it might be because i have around 35 labels and a few other objects on the form. Does anyone know a way to make this not happen? Im in VB08.

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'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
Public Class Form1
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer
[Code].....
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.

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 ?

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.
Protected Overrides Sub OnStart(ByVal args() As String)
Dim tmr As Timer = New Timer(New TimerCallback(AddressOf Upload), Nothing, 1000, 60000)
While Not tmr Is Nothing

I converted one of my projects from Visual Basic 6.0 to Visual Basic.NET and noticed stuff such as:

Clicking on the link it talking about Imports System.Runtime.InteropServices. Which, I am guessing means the project a mixture of both .NET and .COM. How would I rewrite to be totally .Net compatible instead of relying on .COM?Also where would I put code in VB.NET if it was in the Form_Initialize() sub in VB6.0?

I just tried to convert some of my Projects from VB2008 to VB2010 RC, but got compiling Errors while compiling the resX Files. Seems like the reason are ImageLists/Icons, since if I remove them the files compile fine. I already tried to edit the Forms witch are showing the Errors with the Designer. The Designer changed the Content of the resX file lightly, but the error was still present Here the Error(German Version): 'FormsfrmUserTmpBUTable.resx : error RG0000: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.' I recall a similar error in the Beta, but since I can't find it anymore, I guessed it was fixed.
