I am trying to rewrite some code and I am trying to determine if I am writing it correctly. My goal is to make sure that the old code and my new code produce the same results(i.e. are logically equivalent). Are the 2 code blocks below equivalent?

I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?
Can someone give me a site to a tutorial that will help me write a program that will generate a pattern using do while, if else statements,and do until statements.

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?

I am porting over some code from .net (vb) to php and I came across some md5 hashing that I can't reproduce in php. In the .net one there are two functions one uses UTF-8 encoding and the other uses Unicode encoding. The output is a different hash when passed in a string
// First function (returns GUID) Dim oHasher As Cryptography.MD5 = Cryptography.MD5.Create() Dim oEncoder As New System.Text.UTF8Encoding() Dim csData() As Byte
[Code]...
but they both produce the same result. Is it possible to produce the same results in php with md5 hashing?
I'm using the below code to produce a ToolTip for each row of a ListView.
When moving vertically across the ListView a ToolTip will appear when the mouse touches between two rows - bypassing any of the ToolTip's options.
Private m_HoveredItem As ListViewItem Private Sub ListView1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles lv.MouseMove
[Code].....
I'm not using the ShowItemToolTips property of the ListView because I want to have a more formatted ToolTip (ToolTipIcon, Title etc) I don't believe these options can be set for the ListViews ToolTip?
I've updloaded a sample project of the issue here: [URL].
I am now looking for a way to produce pdf files from xls files. Since the completed programme will be distributed to others, it would have to work on environment without the "pdf producer" I am using.Which is the "pdf producer" to use"?I am now working on the express version of VB 2005 (which does not have crystal report). I have acrobat 8.0 installed but have not figured out how to do that...
I noticed that when I build a given C# or VB.NET source to produce a DLL, the binary output is different each time. It would be helpful for our build / deployment process if this was not the case. Can I control this?
I am trying to create a custom datasource control.
I have been following this article to the letter (I think...).
I have a skeleton / basic implementation of my datasource, however when I declare it in the markup and try to statically bind it to a gridview, I receive the following error:
The DataSourceID of 'grdVw' must be the ID of a control of type IDataSource
This seems extremely strange to me, since my datasource inherits from DataSourceControl, which in turn implements IDataSource. Even if I explicitly implement IDataSource in my custom datasource, it makes no difference.
Why I cannot get a variable to come in. I keep on getting the error "Expression does not produce a value" for one of my Dims.
Imports System.IO Public Class Main Dim image_1 As Integer = Openimg1.FileName 'The line below is the one causing my problem Dim image_2 As Integer = My.Computer.FileSystem.RenameFile(Openimg1.FileName, "_hid" + System.IO.Path.GetExtension(Openimg1.FileName)) [Code] .....
So basically, how can I create a variable from something that has yet to be created?
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click If UsernameTextBox.Text = ("username") And PasswordTextBox.Text = ("password") Then MainMenu.Show(Me.Hide) Else MsgBox("Wrong") End Sub
But it gives me the following error:
Error 1 Expression does not produce a value (on Me.Hide)

I have 36 numbers in sets of 5. (eg. 1-2-3-4-5, 2-3-4-5-6 etc..) I need to find all the possible combinations of these numbers which total the same sum. For instance the lowest sum would be: 1 + 2 + 3 + 4 + 5 = 15. The highest possible sum is: 32 + 33 + 34 + 35 + 36 = 170. Now every five number combination within these 36 numbers will sum up between 15 and 170. How would I go about this in vb.net to produce all the possible combinations which would total say 92.
I want to re-produce the equivilent of the DowArrow sign on a VB2010 Form label. label1.Text = Chr(ConsoleKey.DownArrow) doesn't work. The nearest character seems to be ASCII DEC 30 value., which will do fine, but Is there anyway I can reproduce this char on my form label, using one line of code, viz- label1.text =
I've been working creating a few programs in visual studio 10. These work fine on my own PC because I have the .net framework installed. However I need to be able to distribute these programs as a single .exe file download from our website and also as a single .exe file via CD.
Most of the PCs which will be installing my programs won't have .net framework installed and I don't want to force people to have to download the files from the internet (it just seems like so much hassle and I can't guarantee that everyone who wants to install my programs will even have access to the internet).I know that I can set pre-requisites in the publish tab and I have done this whilst setting "Download prerequisites from the same location as my application". I've already downloaded the redistributable files WindowsInstaller-KB893803-v2-x86.exe and dotNetFx40_Full_x86_x64 and I've put the files in the same folder as my project.I then go into the publish wizard and select that users will install the application from a CD-ROM or DVD-ROM. Unfortunately I then get the following errors:
Error 2 The install location for prerequisites has not been set to 'component vendor's web site' and the file 'WindowsInstaller3_1WindowsInstaller-KB893803-v2-x86.exe' in item 'Windows Installer 3.1' can not be located on disk. See Help for more information.ConsumptionCalculatorDraft1
Error 3 The install location for prerequisites has not been set to 'component vendor's web site' and the file 'DotNetFX40dotNetFx40_Full_x86_x64.exe' in item 'Microsoft .NET Framework 4 (x86 and x64)' can not be located on disk. See Help for more information. ConsumptionCalculatorDraft1
For my applications I created a class to produce custom cursors. One of them is a waitcursor with a percentage in it. It has several backgrounds each one with a filled circle on it and they are positioned in a circle it self (a bit like the java wait thingy). Since I put it in my application I started to get errors at different places in my code, but all related to some memmory problems.
