Im trying to search the entire active directory to look for a group and then see if the current logged on user is listed, then take an action based on that result.So far i have the below code which doesnt return the users who are members of the group MyTestGroup. Could anyone assist or guide me to see how i achieve this?
I have a 3rd party object that gets passed to one of my methods. The object contains 20 or so string members. How can I easily list all of the string names and their values?
I have an application that reads data from a SQL query into a list corresponding to the rows of the query. So, I have something like this:[code]What I'd like to know is if I should be using a class (as above) or a structure, and what the difference may be in terms of memory or runtime, if any.
In C++ using std::list, this is a simple matter of erasing what an iterator is pointing to (the erase statement returns the next valid member of the list).What's the best way to iterator through a list and remove members that match a certain criteria?
I'm working on small project for my site... basicly we have over 600 memembers.. and every day new member registers as we can keep of track of all the new members we would like to do the following
By CLicking Button Importing members.php list in to our program so we can see all the new members that have registerd
This is good for our modirator so they can keep an eye out on new members
SO basicly
I click button and my program grabs my user list from my website and puts it in my list box ( but program will have to go to page 2 then 3 and so on and so on )
Need to display the Gold, Silver, And Bronze members in a list box from a TXT file. Have problems isolation each group. When I run the program all of the name in the TXT file come into the list box.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click Dim strMembers As String, objStreamReader As System.IO.StreamReader
Application: Arrays are to be used for this. When button Add Student is clicked it should add all the information for a student and when Show Student button is clicked it should prompt the user for student's last name and student's information in a message box. Class ranking list box has an enum function to it and has to be stored be show along side other answers.NOTE: FindItemIndex if from the last application I did, i am suppose to use it in this one,so you can modify it the way you want.
I have a Generic.List(Of ImportedVehicle) - ImportedVehicle being a simple class as below.There is an enum property which is marked as public.When I serialize to XML using an XMLSerializer, the enum's value is just set to it's default value (which is NotAllocated) and doesn't actually represent the value that is set in code.[code]
a table of addresses and a bindingsource for the table a enum list of address type: 0 = "Mailing", 1 = "Physical", 2 = "Shipping" etc...
I would like to bind the datasource of the combobox to the enum so it displays "Mailing", "Physical" etc. Then I would like to change the bindingsource position of the address table based on the user selection of the combobox.
Here is what I have so far:
cbxAddressName.DataSource = New BindingSource(ApplicationEnums.GetEnumList(GetType(ApplicationEnums.CompanyAddressType)), Nothing)
I'm trying to declare an enumeration and one of the names I'd like to use for an item is not usable apparently. Where I am declaring 'STEP = 3', I get this error message in visual studio: "Statement cannot appear within an Enum body. End of statement expected." Is it possible to use STEP as an item name somehow? [Code]
Which is better, using a nullable enum or adding the value None=0 to your enum list?Using nullables requires more code, but I kind of like it since it forces me to think about the possibility. Otherwise I'm liable to forget about the None enum and fail to account for it being a special case.
Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?
I migrate between C++ and VB.NET in my coding ventures... which leads to the occasional confusion about when something is by value or by reference in VB.NET.Let's say for example that I have an array of MyObject which is populated with a bunch of objects.
dim MyArr(5000) of MyObject. let's say that the information from this array travels throughout various data structures:
dim MyList as new List(of MyObject) for i as integer = 0 to 5000 step 1000 Mylist.add(MyArr(i)) next
Under the above scenario, I believe everything is by reference. If I extract an entry from "MyTable" and modify its MyObject Members, I think that the original in MyArr will be modified.However, I have run into situations where I thought something was by reference, and it was by value. Are items always added to containers by reference, or are they sometimes added by value?
I'm having some headaches using Structures and functions that return Nothing in VB.NET. [Code] In the previous code, when I return Nothing as result of Foo function I'd expect that st is Nothing. But this is not what happens. Then I found in MSDN documentation: Assigning Nothing to a variable sets it to the default value for its declared type. If that type contains variable members, they are all set to their default values.
So I discovered that when I assign Nothing to a structure, all its members are set to their default values, instead of the structure itself.
Also, I tried to make st a Nullable type by declaring: Dim st As Nullable(Of Test) = Foo()
but, still I can't check if st is Nothing by using: If st Is Nothing Then
or If st.Equals(Nothing) Then
So, questions:
1 - Is it possible to assign Nothing to the structure and not to its members? 2 - How can I check if a return structure value is Nothing?
According to a mspress book (MCTS for Exam 70-536 .NET 2.0): You might have version compatibility issues if you ever attempt to deserialize an object that has been serialized by an earlier version of your application. Specifically, if you add a member to a custom class and attempt to deserialize an object that lacks that member, the runtime will throw an exception. In other words, if you add a member to a class in version 3.1 of your application, it will not be able to deserialize an object created by version 3.0 of your application.
Now... As curious as I am I went and created a project, serialized a class, added a new member and attempted to deserialize the class to the new object. To my surprise it worked and the newly created member was set to null by default (even if it had another default value).
i have to develop API in .Net 4.0 which can be used in VB 6.0,i know how to use this and currently i am using my this API in VB successfully.but Stuck at one place,i have collection class and i have to expose it to VB with having functionality of List class of .Net.[code]i know that generic is not supported in VB, but i think with this declaration in VB 6.0 it creates interface class for class B as IList.but in VB using object creation of class B it doesn't provides me members of LIST in intellesense like (Add,Remove of List Class)
Why does intellesense show shared members? e.g:Dim x as doublex.epsi 'Epsilon will show up as a valid member in intellesenseIs there a way to change this behavior?
When I pass an an object 'MyObject' which implements 'IMyInterface' to a method parameter declared as IMyInterface, I understand that this method parameter 'sees MyObject through the eyes of its interface'.
