I am having a problem in paging for XtraReports. How can I improve the report paging from runtime and also I would like to initialize the reportviewer from pageload.We are designing the reports from runtime , so the data on multiple pages is not working i mean I am not comfortable with it. I woulld like to do paging and limit the number of records on the page from runtime.for example i would like to add a PageInfo component and add a "Go to page no.." like this.

I have worked in Windows Forms for years, and still do. I'm not acquainted at all with the ASP.NET technology and no other Web related technology. I have worked with:
Oracle Form Builder;
Visual dBase 7.5;
Delphi 2.0, 3.0 and 7.0;
Sybase Power Builder 10.5;
Visual Basic 6;
Visual Basic 2003/2005/2008;
And ultimately, Visual C# 2005/2008.
I'm mostly a C# programmer with a growing experience in VB.NET for the current year. What would be the way to go to learn WPF the best possible way while taking into account my experience? And I'd like to know, will learning WPF improve my skills in ASP.NET and the like?

I read a text file every second..[code]The file is generated from another program and it's costantly updated more times per second.The sense of the code (StartIndex) is to read only the rows that I have not read from the last time.The code works without problems until the file is about 2.5 Mb in dimensions... for higher dimensions I have problems and all becomes very slow.Using and fs.Dispose() are like Microsoft suggest (and in fact if i run the code analisys I have no problems), but surely the problem is not here.The question is: is my code right or there is way to improve the reading?? Is there way to read only the tail without to open the whole file?

I'm currently in a programing class for vb.net. It's my first true exposure to OOP and I'm looking for some advice on areas where I could improve. I was wondering if someone would be willing to look at one of my programs that I have written and offer advice on areas where I can improve and things that I made much more complicated than they need to be. I'm not looking for a line by line critique just a general look at things to improve upon in the future.

i'm developing vb.net application. There are 10 ways of transactions. I want to produce 'Purchase register report'. For that I want to find what amount of effect has been made by each transaction on ledgers of 'Purchase account'. Purchase account has almost 30 ledgers. And transactions can produce about 10000 rows in database for a year. Now if I produce month wise report for a year, there will be 10000*30=300000 row scanning which makes it very slow in execution.

I'm currently writing a football management game (Australian football) and would like to pretty it up a bit. The match engine simulates each player as a small circle, much like the old Championship Manager games. While I'm fine with this style, I'd like to improve the look. I'm just using the simple graphics tools in VB to draw circles and the oval in the background which they play on. They move around using a timer. It just doesn't look very good. The movement isn't smooth and the circles look jaggy and unprofessional. Given that I'd ultimately like to release this product, I want to make it look a lot better.
What are some 2D graphics engines that I should look at? I don't need fancy animations or anything, just some nice smooth movement and nice looking circles. Doesn't seem like I'm asking for much does it? It'd be also nice if I could add in a chrome-like look or something along those lines.
As for the menus and such, well, they are currently just the boring grey VB style. That's fine for now but, as mentioned earlier, I want to release this game at some point. How can I change all of the menus and such so that this doesn't look like a game made in visual basic...basically. I've seen skins before but I'm not really interested in giving my game some generic style. I want to be able to customize all of it for myself. I just don't know how to! Simply fiddling with the colours and fonts of the default VB controls isn't enough.

I've a class that has a list of IDs with a function for adding new IDs from a list of objects.I've got this resolved, but I'm sure this can be done with much less code.Public Class Page
Private _IdList As List(Of Integer)
Private _HasNewItems As Boolean = False
Public Sub AddItems(ByVal Items As List(Of Item))
Dim itemsID = From itemX In Items _
Select itemX.ID

In Reporting Service, I need to have a vertical, starting at bottom, bottom-to-top, horizontally middle aligned text.The only way to do this is to create an image in code, and set this image into the title column.See the code below.Basically, it works fine, just that the anti-alias quality is pretty crappy.Is there anything I can do to improve it ?The vertical text is somehow pale, and not full black, and also there is smearing all around the text, in the background color.As well as it appears bolder than the text on the left, but both have format arial, size 8, bold I've tried all other values of System.Drawing.Text.TextRenderingHint.*, as well as no anti-alias at all but the current one seems to be the least crappy.I've also tried to change the image format, to no avail:
Function LoadImage2(ByVal sImageText As String, ByVal sImageTextMax As String) As System.Drawing.Image
sImageTextMax = sImageTextMax.PadRight(15)
Dim iFontSize As Integer = 8 '//Change this as needed

I'm trying to improve my app with some error catching. I have a module that downloads a file from the Internet to a local folder. At the moment, if the local folder doesn't exist, it just crashes here:
strLocalFile = New FileStream(pPath, FileMode.Create, FileAccess.Write, FileShare.None)
with error:
System.IO.DirectoryNotFoundException was unhandled
Message="Could not find a part of the path 'C:Documents and SettingsSimonDesktop estdownload.zip'."
Source="mscorlib"
How can I do something with that error and stop my app from crashing? Ideally, have a messagebox show saying 'directory not found' or similar.

I have a repeater which takes 270 seconds to render and actually ends up crashing all browsers. The SQL to retrieve the data takes about 10 seconds. I wanted to remove the Eval's to see if that speeds up things a bit, but I am having trouble with the correct syntax. I have doubts that this would actually improve performance as I am dealing with 150,000 records. Would a GridView or other control be faster? Would using LINQ to SQL improve performance? Here is the code for the Eval:

I want to print contents of a ListView, currently I can print on one page only so my question is how do I improve my code to print on multiple pages. I've read little about the HasMorePages property but no idea how to use it in this context. Heres my code:I have a PrintPreviewDialog and Print Document to assist in printing [code] I understand most part of this code but not all so its kinda hard to follow the program flow to make any big changes myself so if possible can someone please comment the code a bit? how printing works in .NET because I only understand parts of it so having trouble joining the pieces together if that makes sense?

it's capability to serialize objects. In a future project I will be creating dictionaries which have a Long as a key and a Collection as an item (itself containing two other long values). These dictionaries will be large, containing around 300,000 entries.
I've worked out how serialize and deserialize the dictionary using a binary formatter.
To serialize I use:
Dim myDictionary As Collections.Generic.Dictionary(Of Int64, Collection))
' I fill the dictionary with 300,000 entries here
Dim fs As New FileStream("c: empserialDict.dat", FileMode.Create)

I was updating an old .aspx.vb script that was originally written with dynamically typed variables, like this:
Dim price I updated them to the following format (along with some IsDBNull checks to compensate):
Dim price As String After doing this to all of my variables, the script appeared to run noticeably faster. Is this a real effect of static typing, or is it just a coincidence?

My page contains: GridView1, GridView2, Button1, Button2, DropDownList1 I bind Gridviews to the table selected in dropdown like this:
Dim results as DataTable
Select Case ddl1.SelectedValue
Case 0
[Code]....
For me it looks like a lot of overhead. How can I improve then design and only specify that I'm working on the following record in dropdown list without specifying the Case condition every time? Should I change my design or leave it like it is?
Update:
RunZero, RunOne, RunTwo, RemoveZero, RemoveOne, RemoveTwo, RemoveThree - Execute six different stored procedures.

i need to create multiple threads to improve a function on my program. it is a simple thing really but it's slow and if multithreaded it can improve the speed some thousand times. my program uses a dll to check the MX record of an e-mail from a textbox called emails if the mx record is correct then it validates that domain, if not, it sends to an error textbox with that mail my problem is that im reading a lot on multithreading and i dont have an idea how to make something like this: for x=0 to emails.lines.count -1' start a thread that runs my function next if i can limit the number of threads to avoid crashing it would be good.
