View 10 RepliesHow To Have More Than One SQL Statement That Will Control Data Flow
May 12, 2010I am wondering how to have more than one SQL select statement inside my window formapplication that will control the data flow, as i am a newbie in visual basic.net 2005. This is because I am working on a Alarm Application Notifier which will alert the guard on duty as well as inform him the alarm location. The guard's computer screen will be showing the premises and the button will blink at that location where the alarm is. So if the alarm is at block A for example, the guard screen will show block A button blinking.I have already done the first part but i am STUCK at the rest as to how am i going to seperate the conditions for the 3rd to 4th building .The bottom is for the first building code. The data is from the sql database.

Sql Server - SSIS - Killing Excel.exe When Data Flow Task Fails?
May 10, 2012How can I kill the excel.exe process in SSIS during the data flow task when it fails? There could be multiple instances of Excel.exe running from other packages that are perfectly valid so I don't want to loop through all instances killing them.My problem is that during the data flow task the process will sometimes fail due to a sheet that is named incorrectly or missing columns. This keeps an instance of excel.exe running which is now an orphan task eating up resources so it needs to be killed.At the same time there are other SSIS packages running that are accessing their own excel.exe process and aren't having any issues. So how can I kill the orphan excel.exe process without impacting the other excel.exe process?
View 2 RepliesIDE :: Data Source Disappeared - Recreate My Data Source From The Entry That Is In App?
Feb 10, 2012I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

View 2 RepliesConnect A VB Application To An MS Access DB By Adding A Data Source From The Data Menu?

If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)
If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB
How Is WPF Data Binding Using Object Data Source In Visual Studio 2010 Done
Apr 23, 2010how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.
Multiple Combo Boxes Showing Data From The Same Data Source?
May 10, 2010I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

View 5 RepliesAccess Other Data Fields From Combo Box Data Source?
Nov 4, 2009I have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.
