If I can this, tell me how can I do this.

IDE :: 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 4 RepliesAssign A Value From A Listbox To A Textbox?
Feb 29, 2012I have an application in VB.Net that displays the results of a math operation to a listbox. For example I have the 12345 + 12345 = 24690. What I'm trying to do is to have the first 2 numbers (12345 and 12345) copied to 2 different textboxes when listbox item is selected. Here's the code I have so far:
'Make sure that we have a selected item before continuing
If listBox1.SelectedIndex = -1 Then
Return

During runtime it only works with index 1 when it gets selected. I have 10 records being displayed (0 to 9). None of other indexes are being shown at the textboxes.

Assign Index On Combobox/Listbox?
Jun 15, 2009Trying to learn VB 2005. So my questions might tend to use the logic from VBA/VB6.
So, my question is, is it possible to assign indexes on the listbox/combobox? What I have is an ID and a Description from a table and would like to display it on listbox/combobox to allow user to choose from by looking for required description. When selected the ID will be used to search for other information related to this ID.
I manage to display the description but how to assign the IDs?

Cannot Assign Selectedindex To A Databound Listbox If It Has No Parent?
Mar 22, 2012It appears that I cannot assign the selectedindex for a databound listbox if it has no parent, but I can do so if I have populated the list "manually" from the same datatable. In my code example, the "if" line toggles between loading a list via data binding and loading a list "manually" (both use the same data table). In each case I attempt to set the selected index afterwards. With manual loading, the selected index is set; with data binding, an error is thrown (which can be avoided by assigning the listbox a parent, but the "manual" equivalent doesn't need this). Is this a bug?

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.

I would want the timers to be called "Compteur" & ROWID. This really is necessary.I need them to have different Ticks and so that some can be enabled all at once. Basically it is for a project tracker to count the time you are working on the current project. However you could indeed work on many project at the same time.
