VS 2008 Exporting To Excel Faster?

Dec 9, 2009

I am currently exporting from a DataGridView to Excel by looping through all the rows & columns in the DGV, which is very slow when you have a lot of rows. Here is the code I currently use:

For i = 0 To Me.DataGridView1.Rows.Count - 1
For j = 0 To Me.DataGridView1.Columns.Count - 1
xlWorkSheet.Cells(i + 2, j + 1) = Me.DataGridView1(j, i).Value.ToString().Trim
Next
Next

Is it possible to export an entire row to excel, instead of having to do it one cell at a time? I'm just looking for ways to make the process faster.

VS 2008 Make A Function That Does What This One Does But Works Faster?

Oct 27, 2009

I have a function that I use quite a bit that I wrote more than 2 years ago. It works fine but recently I saw how it can use up a good deal of time under certain condition. Here's some code that uses the function SelectValue The function works so that if you had N which you plug into the function rising continuously while SelectLimit was set to 255 then SelectValue would match N until N reached 256. SelectValue would start to descend to 0 until it reached 0 and then it would again ascend to 255 and the process would repeat. So SelectValue(255, 255) would return 255 and SelectValue(256, 255) would return 254. SelectValue(257, 255) would return 253.

Option Strict On
Public Class Form1
Dim sw As Stopwatch

[code]....

The function works exactly as I want it to but if one of you knows a way to write this so that it will process faster then you can let me know. I get a result for processing time of 6.11 seconds on my computer for the above code.

VS 2008 Adding Or Comparing Faster At Binary Level?

Sep 16, 2010

I was just wondering if a computer would add two numbers together (positive) faster that comparing two numbers.

I was thinking that it would be comparison (best case) due to the fact that the 0th bits could be different right off the bat. Where as when adding, moving from bit 0 to N is mandatory for addition.

But then again a computer may add/compare differently than I am imagining.

VS 2008 Which Method Would Be Faster For Gathering And Storing Data

Nov 16, 2009

I have a simple multithread application that stores updated data from a list of websites. After each thread gathers data, it then store the data into the same text file. I am now thinking of having each thread store the data directly into a arrayList, and after a certain amount of time past, store from the arrayList to the text file. Which situation would enable the application to complete its task faster?

Is C# Faster Than .NET

Oct 1, 2010

You'd think both are the same. But maybe it's the compiler that Microsoft has used, but I've noticed that when compiling two very small programs, identical logic. VB.NET uses more IL instructions.Is it true than that c# must be faster, if only because its compiler is smarter.

Faster Than A Listview?

Mar 11, 2011

A long time a agp I settled into a listview as an indicating device. I do not use pictorial modes or graphics. Just listing and multicolumn listing.I am also a performance bug and I have written realtime monitors for monitoring cpu activity in real-time and normally rum them starting at bootime. Lately I have found that the listview throws away time. In a tight loop, the list view does not take all cpu time available and the listview is relatively slow.

Does anyone know of a control like the list views only it's faster? Multi-colored and multi-columned are musts.

Foreach In Faster Than In C#?

Mar 12, 2009

My co-worker said that in a previous interview, he learned that foreach is faster in VB.Net than c#'s foreach. He was told that this was because both have different CLR implementation.

Coming from a C++ perspective, I'm curious on why this is and I was told that I need to read up on CLR first. Googling foreach and CLR doesn't help me understand.

Does anyone have a good explanation on why foreach is faster in VB.Net than in c#? Or was my co-worker misinformed?

How To Get Filename Faster

Mar 29, 2010

I have a directory with more then 350.000 files in. I need to process every single file and move them to an other folder. When I use the dir() method it takes a few seconds before if it returns the first file found.
dim foundfile as string = dir("d:")

In the documentation there is this:
"The My.Computer.FileSystem Object gives you greater productivity and performance in file I/O operations than the Dir function. See My.Computer.FileSystem.GetDirectoryInfo Method for more information."

But I can't find any method that is faster then dir, and gives the same result. I can't use this method below because it takes for ever to load......
For Each foundFile As String In My.Computer.FileSystem.GetFiles("D:")
Next
It just does not work fast...

When I use the Dir() method it takes like 5 sec, and it uses 100% cpu... it is just not a option. How do I get the same function as the dir method but better performance? (I use visual basic 2008).

Asp.net - Create CSV File Faster

Apr 13, 2011

I create a CSV file by getting a datatable then looping through that datatable and writing eachline of a CSV file. My data source usually has around 65,000 rows in it. This process takes several minutes to download from the browser. The problem is that locally and on dev it doesn't take too long, but on the client they usually timeout.

Is there a faster way to generate this file?

Function GenerateCSVFile() As String
Dim stuPro As New studentProvider.StudentProvider
Dim emailCenter As New EmailCenter

Faster Way To Copy Table To SQL?

Apr 2, 2010

I'm converting a process from VB 6.0 to VB .Net. The process copies a table from one database table to another database. In many cases they are not linked so a "Select * into Table2 from Table1" is not a solution. Also the source table may be a temporary global table that has a unique structure. The current process reads the source table into an ADODB recordset, obtains the columns attributes to create a new table, creates the new table, builds insert statements from the source table, and then inserts the rows into the new table. I'd like to take advantage of any .Net features that may be more efficient than that. Can anyone point me in the right Direction?

How To Process Data Faster

Dec 4, 2009

I'm receiving a lot of data at the rate of 19200. I'm using read byte to assemble a buffer and process it. When I receive certain data I need to reply to the sender. I noticed that my replies are not fast enough. So I did a test where I unplugged the sender and noticed I was still receiving data! That I found was because the serial port buffer still had data from the sender that I didn't process. Anyhow I'm using Visual Studio 2005, the serial port object. How can I process the data faster. Would something like SerialPort1.ReadExisting or ReadLine work faster?

Bmp File Reading Faster After First Time?

Jan 19, 2012

im making a program to "test darwinism" in C++ and im showing the results in a VB 2010 express app, the results consist of .800x800 bmp files displaying creatures eating , reproducing and evolving. the VB app only has a picture box and it changes the .image param in a timer so that it looks like a video : for example it reads : frame0.bmp then frame1.bmp etc. I get about 30frames seconds with this method (and alot of GB of .bmp files..)the .bmp files are read slower if they never have been read.. for example I get about 5frames/sec when im using new .bmp files while I get 30fps if the files have been read once.. only opening and closing the files doesnt make them load faster, I have to load the bitmap image. I noticed that opening the directory where the .bmp files are and letting windows make preview icons make them load faster too.. that looks weird to me.. something with indexing ?also , my c++ program which creates the .bmp files goes really fast for the 500first but then it becomes slower (even if It just writes black .bmp files in a closed loop). could it be that the hard disc gets overwhelmed by all the writing ?
