i have a program in VB.Net 2005 and my problem is that it runs very slow. I mean, it takes some time for the Form to be displayed even if it is not doing anything in the Form_Load event. Do all programs in VB.NET 2005 act like that? my programs in VB6 would display the Form instantly.
View 4 RepliesIm using RichTextBox from Visual Studio 2008 to show various RTF content and it is slow. I mean really slow. Is there any way to improve the loading speeds of LoadFile function?I tried to load directly from memorystream (without saving file to disk) but it's still slow.I read plenty info about how RichTextBox is slow and all. Has there been any improvements in Visual Studio 2010?

View 2 RepliesI need to copy listview items text, not subitems to array without looping, how do I do this?
View 2 RepliesBasically what i need is for something to look at the items in a list box then compare it to the contents that is in the database. The issue is that the listbox can have more than one of the same item. For instance, LstBox_Order.items(0) could be the same at any position in the listbox. This code works, but it is slow if there is like 10 or more items added.

View 12 RepliesI 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.

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.

View 1 RepliesYou'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.

View 2 RepliesA 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.

View 9 RepliesMy 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?
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).
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?

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?
