i have a code like this
'bug_message is a public shared property
Public Shared Sub bug(ByVal bug_message As String)
msgbox(XX_format(MyClass.bug_message, bug_message))
End Sub
however i get this error: MyClass is valid only within an instance method. I do not wish to use the actual name of my class, and if i could i would prefer to keep the name of the argument as bug_message as well.
I've got an .aspx page with this in it:
<%@ Import Namespace="System.Web.Mvc" %>
<%= AssetController.ScriptTag("/js/Community/CommunityWizard.js")%>
And I have an AssetController class:
Imports System.Web.Mvc
Public Class AssetController
Inherits Controller
[Code]...
What gives? I don't understand why I can use this controller everywhere in our ASP.NET Forms/MVC hybrid application, but not in a view.
EDIT: In fact, when I type <% System.Web. into the .aspx view, Mvc doesn't even appear in Intellisense!
I am having a Friend Class InterceptingChannelBase class.It has a property as below:
Protected ReadOnly Property InnerChannel() As TChannel
Get
Return Me.innerChannelT
[code]....
This class is being inherited by (Friend Class InterceptingInputChannel) class which in turn contains another (Private Class TryReceiveAsyncResult) class.The property above is being used in this private class as below:
Public Sub New(ByVal channel As InterceptingInputChannel(Of TInputChannel), ByVal timeout As TimeSpan, ByVal callback As AsyncCallback, ByVal state As Object)
MyBase.New(channel, callback, state)
[code]....
I am getting the error on the above underlined statement saying that Protected Readonly Property InnerChannel is not accessible in this context because it is declared asa Protected.As far as i think,if i declare a property in class as 'Protected' then if this class is inherited by 'another' class then i can use this property and it should not throw an error.
Dim box As MultiTextBox = New MultiTextBox
Dim i As Integer
for i = 1 to 3 Step 1
lengthWidthHeight = MultiTextBox.GetItemValues()
Next i
This excerpt of code is using the NXOpen API. In the NXOpen API, the MultiTextBox class is public. However, when I compile the code I get the message:
'NXOpen.UIStyler.MultiTextBox.Protected Sub New(ptr As System.IntPtr)' is not accessible >in this context because it is 'Protected'
My question is, how am I getting an error about protected scope? Could it also be that the API documentation is incorrect?

View 5 RepliesI have a large problem with inheritance in vb.net. The problem is the following:
I have 2 forms => frmBase and frmChild
In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.
But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()
I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.
I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it.It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is:
First: "PerformLookup Time: 40:842"
Second: "initIndex Time: 45:873"

Basically in visual basic 6 I could access word tables in existing templates with the code owordactivedoc.tables(1).select() where owordactivedoc refers to the active word document and tables(1) refers to the first table in the template.Trying the same code in VB 2003 just leads to errors. Secondly how do I access bookmarks or alternatively word variables.Furthermore how do one deploy web.services. For example the current program I am building is for another computer. Simply copying the web service to Inetpubwwwroot dont work because it is not picked up by the Internet Information Services program. I have to create the web service in vb2003 on the other computer change msconfig manually. Copy and paste the existing service vb file in the created folder replacing the empty vb file.

View 2 RepliesI'm currently using an unmanaged library written in C++ and imported via <DLLImport()> to access a dos virtual device driver, and that works fine. However, I'd like to be able to do this via my .NET application (without requiring an accompanying DLL). So, I'm trying to write to the virtual dos device using the kernel32 API and WriteFile, however I receive the error: "Attempted to read or write protected memory."
Mapping to the device with DefineDosDevice and CreateFile (also in the kernel32 API) works fine and returns a valid file handle, however when I attempt to write to the file it fails. I've even tried marshaling the data to an unmanaged block of memory using InteropServices (AllocHGlobal and StructureToPtr) and then writing it from there, however I still receive the same error.
I have written a code to take complaints and give that complaint a number automatically. For that i have created a "fno" named variable in settings.but somehow i cant change the value of it and i get this error "Attempt to access protected memory"

View 6 RepliesI set up a worksheet with locked and unlocked cells. I would like to protect the worksheet; however, this grays out the "Update Values" and "Change Source" buttons in the Edit Links window. One workaround is to ask the users to Edit Links through an unprotected worksheet within the workbook, but that seems like a nuisance. Is there VBA code to allow "Update Values" and "Change Source" through Edit Links, in a protected sheet?

View 2 RepliesI have several files that are linked to other files but due to certain information in each file they are password proected. I wrote the program to open each file and than close in a particular order so that all files are updated and than closed. Here is the problem: I can not get the program to auto enter the password.
The code is simple so far
Workbooks.Open Filename:= "S:EveryoneBudgetBus Dev Ex.xlsx"
(MISSING CODE FOR PASSWORD)
Windows("DirecPath Budget - Bus Dev Non-Ex.xlsx").Activate
ActiveWorkbook.Save
ActiveWindow.Close
The problem is that I have to enter the password in for all files. Which of course the average user will not have. Can somebody please help with the code for the password. If you post a code use the password "team" so that I know exactly how to do the code.
