I need some help with a LINQ query in VB.Net, please.[code]This works, and returns me the data I need to work with. Now I want to iterate through the groups, using a For Each construct. like this: For Each x In drivers Next...However, the compiler is barking at me, telling me that the "'x' is not accessible in this context because it is 'Friend'."
I'm trying to match up a specific group name and see if it exists for the currently logged in user using Active Directory roles. If the Group Name exists for the Current User, I want that group name to be displayed in a drop down list. Example: If current user is in BIG Group, display BIG in drop down list.Problem: All I am getting is SIDs and I'm not able to get anything to match up to the group name and nothing will show up in the drop down list.I also get the following Error:Error: Object variable or WIth block variable not set.How do I fix this?? here is the code I am using:
Private Sub GetMarketingCompanies() ' code to populate marketing company drop down list based on the current logged in users active directory group that
I am writing an application and I do not know how to reference a group of controls inside a group box. I will include the code I have written so far and a picture with a detailed explanation as to what I am trying to do. Feel free to comment on any discrepancies that you may notice in my code.
Code:
Public Class Form1 ' The following class-level constants are used ' to calculate the price of the model Const decCOUPE As Decimal = 18000
I want to divide the content in my application to groups each group has its own rectangle border with the group name located at the top border, i've seen it before and i'm not sure what is the correct name of this control, anyone knows what I'm talking about ? EDIT: Ok, I found the Groupbox Control but how do i use it? should i just drag other controls inside it or i should add controls directly into it?
I have this code I've used multiple times to add and remove users from AD groups, but when I try to use it to remove an AD group from another AD group it fails with "The server is unwilling" [code]...
This works. In my controller, I can access my jsonObject like this: obj.ID '123
But I haven't got an idea yet how to iterate through all properties. I can get all member names as a IEnumerable String Collection (obj.GetDynamicMemberNames()), but how do I use the TryGetMember method to access the value of a member ?
I have a VB Web Application with a bunch of textboxes on it in Default.aspx (Using the basic template in Visual Web Designer 2010 Express). I'd like to iterate through those textboxes using some sort of VB solution if at all possible and clear them when the user presses a button. I've tried using something like this:
Dim cControl As Control For Each cControl in Me.Controls If cControl Is TextBox Then
[This is a simplified example] I have a collection ("myCollection") in which exists three entries: ("hello", "goodbye", "welcome"). I want to iterate through the collection and if in the collection there is the entry "welcome" I want to take one action, if that entry doesn't exist I want to do something else. Like this (pseudo):
I have a simple XAML file with a grid in it and textboxes. But when using my code it does not find the textboxes by iteration.
VB.Net:
Dim ctl As FrameworkElement = Me.MainWindow
Code:
Dim ChildrenCount As Integer = VisualTreeHelper.GetChildrenCount(ctl) 'ChildrenCount is always zero For i As Integer = 0 To ChildrenCount - 1 Dim Child As FrameworkElement = VisualTreeHelper.GetChild(ctl, i)
I use the BS Filter and would like to iterate the filtered dataset of the DataTable using the Bindingsource.
I know I can do a MoveFirst and the MoveNext and each time using the BS.Position get the correct row in the underlying DataTable. But how do I know when the sets ends? I'm sure there must be such a property, but what is it?
if I run the following code,For each itm in MyList Next if the list is nothing i got an error..Is there a better way to deal with list=nothing than using a condion like [code]
I have a structure with types ranging from thread's to control.what im looking for is a easy way to iterate through those item like For eachbut i couldn't get for each to workis there a way to do it
I'm debuging an complex calculation object in my project, and I'd like to show its various and many properties in a textbox, to make my tests easier.
Can I do something like
for each p as someKindOfProperty in MyObject1 debug.print(p.name & " - " & debug.print p.value) textbox1.text = textbox1.text & vbcrlf & p.name & " - " & p.value next
I have List (Of Report). Report has 90 properties. I dont want write them each and every propertiy to get values for properties. Is there any waht to get propeties values from the List
Ex: Dim mReports as new List(Of Reports) mReport = GetReports()
For each mReport as Report In mReports 'Here I want get all properties values without writing property names next
We have a common component in our source which contains all the enums (approx 300!) for a very large application.Is there any way, using either C# or VB.NET, to iterate through all of them in order to perform an action on each one?
How to iterate all "public string" properties in a .net class is almost relevant but the enums I am dealing with are a mix of types.

Lets say I have 30 text fields in a Frame on my form, and I want to set them all to disable (so users can't edit them).Is there an easy way to walk through those fields without having to create an array of text fields?
I.E., in ... VB 6, with an array of text fields, I can do something like this: For i = 0 to 10 txtfield(x).enabled = true. Next i
Is there something in VB.NET where I won't have to use an array of controls, something like this (assuming all txt fields are in a frame):
Is there some way I can iterate through all available attributes for a given html element something like: for each lo_Attrib as attribute in htmlElement.attributes .........
I need an elegant way using VB.Net to iterate through a range of IP addresses when the input will come to my app as a string in this format: 192.168.100.8-10 This range would include 3 addresses: 192.168.100.8, 192.168.100.9, 192.168.100.10. I found a solution in C# that uses the IP Address class that I could probably convert to VB but it seemed to be way too much code for what I need to do. I could definitely use a bunch of string parsing functions but I was hoping someone already had a simple way of doing this.
I've done some VB Script and I know C++ fairly intricately. I'm having trouble understanding, and making for loops with if statements perform as expected. What I'm trying to do is iterate through a string and turn all of the "a"s into "c"s "b"s into "d"s and "c"s into "e"s? Here's what I've got thus far and I'm keeping the old string intact.
For i = 0 To first_string.Length - 1 If first_string(i) = "a" Then second_string = first_string.Replace("a", "c") ElseIf first_string(i) = "b" Then [Code] .....
I can do this for loop in my sleep in C++, but it seems that the increment counter i is never what I expect it to be. It should start as 0 (first letter of string) replace whichever of the three it finds, then change to 1 (second letter of the string) and replace whatever it finds there right?
I want to see what the different MessageBoxIcons look like. I found some code that jmc had posted but it only gets the names and values, I want to see the names and the pictures.
I asked on SO a few days ago what was the simplest quickest way to build a wrapper around a recently completed database. I took the advice and used sqlmetal to build linq classes around my database design.
Now I am having two problems. One, I don't know LINQ. And, two, I have been shocked to realize how hard it is to learn. I have a book on LINQ (Linq In Action by Manning) and it has helped some but at the end of the day it is going to take me a couple of weeks to get traction and I need to make some progress on my project today.

My needs are simple. I have a console app. The main table is the SupplyModel table. Most of the other tables are child tables of the SupplyModel table.
I want to iterate through each of Supply Model records. I want to grab the data for a supply model and then DoStuff with the data. And I also need to iterate through the child records, for each supply model, for example the NumberedInventories and DoStuff with that as well.
For the record I have already written the following code...
Dim _dataContext As DataContext = New DataContext(ConnectionStrings("SupplyModelDB").ConnectionString) Dim SMs As Table(Of Data.SupplyModels) = _dataContext.GetTable(Of Data.SupplyModels)() Dim query = From sm In SMs Where sm.SupplyModelID = 1 Select sm
This code is working...I have a query object and I can use ObjectDumper to enumerate and dump the data...but I still can't figure it out...because ObjectDumper uses reflection and other language constructs I don't get. It DOES enumerate both the parent and child data just like I want (when level=2).
