IDE - My.Application.Info.Version.Build Returns Wrong Value
Mar 6, 2009We're using team build with AssemblyInfoTask to increment the build number in a nightly build. The build number is displayed in the application using My.Application.Info.Version.Build.This has been working fine for years. But since we branched the sources and started using file references instead of project references (have no idea if that's what causes the problem), the last build number is displayed instead of the current one.
The compiled files (dll's and exe's) have the correct build number, if checked by right clicking the file in Explorer and viewing detailed properties. However when the same exe-file is executed, the UI displays the previous build number.If I edit the AssemblyInfo.vb file manually (just set another number, save the file, and set it back again), both file properties in Explorer and the UI at runtime displays the correct build number. How can this happen? What can be done to avoid this strange behavior?
SQLDataReader - Creating A Small Program To Read From An SQL Server, Loading Result Into An Array
Nov 15, 2011I'm creating a small program to read from an SQL server, loading result into an array, pivoting the array to my liking and mailing it out to selected members of a group. It's going to be run once a day with Windows schedule. I have the connection, query and mail sorted, but not the datareader to array bit.

Find 64-bit Process Info Using A 32-bit Process?
May 2, 2011I have a 32 bit application that shells a second application that can be 32 or 64-bit depending upon the computer it's running on. I only want one instance of the second application to run at a time, and I need the first application to prevent the second from being launched more than once. I want to be able to use GetProcessesByName to obtain the running processes. This seems to work fine. It's when I attempt to obtain the module data to find out what folder the second application was run from that things fall apart.

SqlDataReader Getting Rows When No Data
Jul 29, 2010This is incredibly urgent, I need to present this application in 3 and a half hours.My application checks against a data source to see if a value exists in the database and changes values depending on whether or not the value in question was found.The problem is that I've run the sql query with the value in question in SSMS and no rows were returned, and yet, my DataReader says it has rows.[code]val will only be returned True if the NumberToCheck (in this example 3235553469) exists in the database.Having copied the value of NumberToCheck into SSMS and testing the query there, I can verify that the query does work as expected.No, I can't populate a DataSet because of the volume of information in the table (+/- 9.5m rows). Even with the 'WHERE' filter, the query is too heavy on resources and eventually ends in an OutOfMemory Exception which is why I went with a DataReader.

If I already know the PID, then I can retrieve the CreationDate (I assume which I can use to check for restarts? or is this the actual process creation/installation date) for each specific process, however if a restart occurs the PID will change and my script needs to know what the new PID is without me telling it!

PC Info System - How To Retrieve Date And Time Format
Jul 27, 2011I am trying to read the pc system information so that I can retrieve the time and date format.
My code below:
Dim Info As System.Globalization.DateTimeFormatInfo
Info = System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat
Debug.WriteLine(Info.LongDatePattern)
Retruns in debug: "dddd, MMMM dd, yyyy"
So I have 2 questions;
1) Why is there, a dd after the MMMM.
2) My company has small franchise branch offices round the world - France, USA, etc. What I am trying to do is get the date format so I can decide what country I am in - then when I print out the date on my order labels I can change the date format to suit Americans or Europeans etc.

Adding Objects To A List Fails When Retrieving Data Using SqlDataReader

Multithreading - .NET DataGridView Load Data From A Background Worker And SQLDataReader?
Mar 28, 2012I have a DataGridView that I'd like to load with data that I'm retrieving from a SQLDataReader running in a background worker as the data comes in (it's a query that takes a long time). My goal is for the user experience to be similar to searching for a file in Windows where the results appear in the list as they come in and you can still interact with the window.
I have it working with a background worker and data reader and I'm trying to add the row from the SQLDataReader.Read through using the BackgroundWorker.ReportProgress method. Everything technically works but the flicker is crazy and the form is unusable (probably not because the GUI thread is blocked but just because there's so much going on...) How do I make loading the datagridview "smooth"?

Oct 30, 2009So I transitioned over to Win 7 64 bit, and am starting to incorporate it into my program. I understand that My.System.FileSystem.SpecialFolders.ProgramFiles will resort to x:Program Files if the host system is 64 or 32 bit. However, if the host is 64, and the program is 32 bit, one would need to acess x:Program Files (x86).
My question is this:How can I test an executable to see if it is 32/64 bit, and then apply the proper program folder?
