.net :: Identifiers Starting With An Integer?
Jan 24, 2011
I have a .net dll and when I add it in the references, it goes without any issue. The problem is that its namespaces start with an integer e.g. 3gppsa5.org.AlarmIRPSystem and when I try to use or import it, the intelliSense doesn't allow and says identifier expected.I don't have the source of this library so I can't change it. I know it is compiled and the Object Browser is correctly showing all of its classes and functions. However, I am unable to use it in my code. Is there any way to use it in VB .NET

How do you convert an integer to a usable color (for PictureBox.CreateGraphics)?
The color should start at red, cycle to orange, yellow, etc. and come all the way back around to red again.
This is in vb.net. If I cannot do this, how do I use PictureBox.CreateGraphics with a hex code instead of a pen?

I have a form, user logs in and another form is generated. User submits a query. My problem is that I cannot keep a record of who is making the query.
The user has a uid and usernamae but once the new form is generated where the user submits the query both these identifiers are gone. Is there a way in which I can overcome this?

I am attempting to send a string to a textbox in the webbrowser control and the page I am trying to do this with has random name= and value= fields which makes it difficult to use the typical methods for placing text in the textbox. I have spent quite a bit of time searching and attempting to figure this out and I'm stumped.

I'm looking for a method of generating unique identifiers for a record class being created locally and then persisted in various formats (XML, SQL, etc.) I've seen people using DateTime and GetHashCode, but that seems to lend itself to duplicate identifiers depending upon the sample size. GUID is a bit overkill, as I don't need anything that unique (large) at the global level. I'm also aware of using GUIDs and GetHashCode to get the size down a bit, but duplicates tend to crop up here as well. Any best practice or method for generating simple unique identifiers?

ive got some simple problem i cant understand how to solve.
str(1) is an array and integer(or double, tried both)
a(1) is an array and integer (or double, tried both)
a(1) = a(1) + 1
Label1.Text = str(1) + a
the big part is where i get: operator '+' is not defined for types 'integer' and '1-dimensional array of integer'.why do i get that message and what does it mean? how do i make the code do what i want?

I faced an error when upgrading VB6 code to VB.NET. The error occurs at AddressOf WindowProc
AddressOf expression cannot be converted to 'Integer' because 'Integer' is not a delegate type
My declaration for SetWindowLong is:
Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA"(
ByVal hWnd As Integer,
ByVal nIndex As Integer,[code]....
What is the reason for the error I get?

I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?
Do While Not item Is Nothing
item = item.NextItem
Loop

I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.
After the conversion, the code look like this:
Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer
Dim arginitP As Integer
[Code]...
Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer

I have a LINQ2Entity problem, I want to get the value, string, from a database, so I select FProducts.Serial_number, and to end the query, I do .ToDictionary. The problem is, it tells me that it doesn't have sufficient parameters, to convert ToDictionary. So I need something like select FProducts.Serial_number, Nothing). ToDictionary. Also FProducts.Serial_number, 0).ToDictionary doesn't work.
Sub GetStatistics(ByVal ProductNumbers As List(Of String), ByRef Passed As Integer, ByRef FailedProducts As List(Of String))
Passed = 0
FailedProducts = Nothing

I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:
Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)
[Code]...
I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?

This is giving me a headache. I have this link query here that grabs an ID
Dim mclassID = From x In db.SchoolClasses Where x.VisitDateID = _visitdateID Select x.ClassID And then later on I have this linq query
ViewData("Staff") = From t In db.Staffs Where t.ClassID = mclassID Select t
I've tried quite a few things but to no avail. I've attempted casting, converting, Is operand, etc.

I'm just writing a bit of code to compare an id of integer with an id of integer? for example:
Dim id As Integer = 1
Dim nullId As Integer? = Nothing
Dim areEqual As Boolean
areEqual = nullId = id
When I try to compile the code I get a compiler error: Option Strict On disallows implicit conversions from 'Boolean?' to 'Boolean'. Whilst it's very simple for me to work around this, I was hoping that someone might be able to explain what's going in the compiler to give this warning.

i tried this, but had invalidcast at line 2.
vb.net
Dim a As Array = Array.CreateInstance(GetType(Integer), New Integer() {1}, New Integer() {1}) Dim b As Integer() = CType(a, Integer())
what i'm trying to do is to create an Integer array with LBound greater than 0. any way would be accepted, or can i say this: my function that takes i As Integer() as its argument does not have to check the LBound of i because there is no way LBound of i will ever be greater than 0

I am using Microsoft.Web.Administration to create NEW websites programatically. How do i change all ID's starting from zero? Currently i have about 100 websites and they are ordered like following:
1, 2, 4, 18, 200, 1234, 232324, 2455344 etc. etc. And i want them ordered like this: 1, 2, 3, 4, 5, 6, 7, ... etc. up to 100.This question doesn't have to refer IIS and the Administration class directly.
I just need to change the id like you change the values into database or array/arraylist or generic list.
Means the value with 1234 should be 6 if six is not already taken or 18 should be 3 etc.

I'm trying to execute a 3rd party application, called from a .cmd batch file, called from a self-hosted WCF service. Like this:
WCF --> .cmd --> 3rd party app
For whatever reason, using the Shell command doesn't work fully. It will call the .cmd file, but the 3rd party app won't kick off (I know the .cmd is firing because I have before/after ECHO statements populating a log file). If I double-click the .cmd file from explorer, the 3rd party app will start just fine. So, I figured, maybe try something besides the Shell command from my WCF service.
So I tried the following code, but it won't kick off the .cmd file at all (echo statements not firing). What am I missing here?
Dim psi As New ProcessStartInfo("cmd.exe", "/C " & System.Configuration.ConfigurationManager.AppSettings("ExStream_CMD_File_Path"))
Dim proc As New Process()
proc.StartInfo = psi
proc.Start()
proc.WaitForExit()
The path in the app.config file is valid (just double-checked). Is there anything wrong with the above code?
