The Hierarchical Structure Of A Dataset In Data Source Window
Apr 11, 2011if it matters which of the repeated tables you drag onto forms? I know there's a parent-child relationship between orders and details, which is why details appears "under" orders, but details also appears in other places. What's the difference between its different appearances below?

May 3, 2010I like the new intellisense enhancements for finding members, however, there are 2 problems i have;
1) You can't resize the intellisense window when it pops up? This one is really annoying.
2) There seems to be a fixed font for the intellisense list? Why does it not match the rest of my code window like it used to? I've noticed the same with tooltips.
Threads Debug Window Missing
Apr 7, 2012I am trying to list all the current threads that are running in my application. According to various posts, this can be simply done by selecting Debug -> Windows -> Threads however the threads window is not there. I am using Visual Basic Express .net 2010, am I doing something wrong, or is it not implemented in this version ?
If it is not implemented, is there a simple way to display all the threads that are running. I don't want lots details about them, just what they are ?

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 1 RepliesUse Window Like A Function / Pass In Parameters / Use Window / Get Data Out When It Closes?
Dec 13, 2011I am creating a window that is a generic keypad for editing numerical values on a touchscreen. I would like to press an 'edit' button to create a copy of the keypad window/bring up a reusable version of the same window (I don't care), but pass in parameters: the old value I'm manipulating, and a title to be displayed above the number pad. I would like the user to be able to type in the new value, then press the 'done' key to submit this value and have it sent back to the main application window into my custom control that contains a text box.(I have the number pad's layout sorted out already; I'm already using a variation on it to set a global password 'access level'. It's getting the information in and out that has me scratching my head.) [code]

May 6, 2010I am working with a .csv file that is generated from a Java-based application. It mainly contains contact information. I can see the data when I open it in Notepad, Excel, and Access.

Find Missing Data From Table
May 12, 2010what is the fasted way to get all the rows from table1 that aren't in table2? i have over 4000 rows in table1, i am currently looping through using:
for each dr as datarow in dt1.rows
then i check table2 to see if that entry exists using:
dim rows() as datarow = dt2.select("EmployeID = " & dr!EmployeeID)
if rows.length > 0 then it exists in both tables - dont need it
other wise i copy the row into a third table which ends up being my final collection of rows that are in table1 and not in table2. this takes a really long time. is there a better, faster way that isn't too complicated?

VB 2010 - Multithreading - Missing Some Data That Is Streaming
Nov 24, 2010I am developing a software that catches streaming data. Unfortunately, there is no pattern or sequence on how this data comes in. So what I have initially done is to catch then write to my MS Access DB. Unfortunately, while writing to the DB, I am missing some data that is streaming since writing takes a little bit of time before it goes back to the catching syntax.
I am planning to multithread the DB writing then just call it from my main program. Do guys know any website/tutorial where I can learn the basics for multithreading? I am using Visual Studio 2010. Or if ever, does any one of you have a sample program where I can just learn from?

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"

VS 2005 Missing Operand Error In Computed Data Column?
Aug 25, 2011I'm trying to add a computed column to a datatable that references another column in the datatable. Sometimes the computed column has a mathematical operation applied to it, but in this case I'm just referencing the original column. The code looks like the following:
ReportData.Columns.Add("1_1_US", _
GetType(Single), _
"1_1")
The code isn't actually hard coded as shown above - there are functions that return the values for the first and third parameters - but I checked those and they are returning the expected values and not generating any errors themselves.
The error is thrown when the .Add method is called, and the error states "Syntax error: Missing operand after '_1' operator." It seems to me that it doesn't like the column name, which I suppose I could change and just workaround it at the presentation level. Still, I'm curious. Is this a bug in the .net framework or something? It doesn't mind "1_1" as a column name in the datatable, so why is it having a problem with it in the expression statement?
Access 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.
