I'm using SharpDevelop and .NET 4.0.
My question is this: If you start a new project with a "Windows Application" template, it generates a Program.vb with the following contents[code]...
1. create a blank VS2010 web project called "MySite" targeted at 4.0
2. create a new class object, calling it "class1.vb" (cause it's so unique!!)
3. change default code to read as such...
Namespace MySite
Public Class Functions
Public Shared Function WhatIsTodaysDate() As String
Return Date.Now.ToLongDateString
[code]....
Why is VS asking me to call the namespace twice if I use the "Imports" directive?I'm sure this has got something to do with VS2010 and the 4.0 framework.
I've wrote a class library in vb. it only has a class called MathEx. Now when i add a reference to a test project, i had to refer to the class as MathEx.MathEx is there anyway i could refer to the class as simply MathEx? (in other words i do not wish to have the default namespace added to my class libraries)
View 1 RepliesIs that possible to create a class in vb.net that is not in the default namespace of the project?
for example, say you have a project call sample1, then automatially IDE will have everything default to the Sample1 as your namespace root rather than under global, which is find for most case.but I want to create some classes that is directly under global namespace
I am attempting to move a highly referenced class from one namespace to another. Simply moving the file into the new project which has a different root namespace results in over 1100 errors throughout my solution.Some references to the class involve fully qualified namescape referencing and others involve the importing of the namespace.
I have tried using a refactoring tool (Refactor Pro) to rename the namespace, in the hope all references to the class would change, but this resulted in the aforementioned problem.Anyone have ideas of how to tackle this challenge without needing to drill into every file manually and changing the fully qualified namespace or importing the new one if it doesn't exist already?

View 1 RepliesIf this were a Windows forms project I have used the System.Drawing.Printing namespace to accomplish my goal. However, I cannot import this namespace into a Class library.Overall here is what I am trying to do:I am trying to set the default printer using this namespace on both Windows XP and Windows 7 workstations. I am using Visual Basic 2008. My ultimate goal is to create a COM dll which is accessed from an older VBA program. The COM Dll will set the default printer to a new printer. Execution will return to the VBA program and it will print a Crystal Report. When the Crystal report is finished the VBA code will use the COM Dll one last time to set the default printer back to the original default Printer.But as I mentioned I cannot import the namespace I want to use into a Class library. Can someone give me some guidance on how to either import the namespace into a Class Library or how to determine the Default printer name and to set the Default printer to a different value?
Update: I was able to add the Imports Namespace after I added a reference to the correct DLL in Project Properties. My project is targeted at the 3.5 .Net Framework. The System.Drawing.Printing DLL is not in the 3.5 framework. That DLL is in the 2.0.50727 framework. After browsing and Adding that DLL, everything is working fine.BUT this leads to a new question. How would determining the default Printer be accomplished in the 3.5 .Net framework?Secondly, am I asking for trouble having a project target the 3.5 framework AND including a 2.0.50727 component in the same project?
I have built my first VB 2008 application and now I want to install it on other Windows 7 & Windows XP computers. I have tried various Install Programs but they all giving similar problems. Is all I have to do is copy the contents of the bin directory to the other computers? [Code] When I try to run my application I get the message "MyApp has encountered a problem and needs to close". Can you suggest what I am doing wrong?

I am working in visual studio 2010, framework 3.0.I want to enumerate the Audio Recording devices on Vista and Windows 7 PCs. With the help of Core Audio APIs, this is completed successfully. Now I want to change the default state of devices and also I want to set the state of Disabled device to Enable. In Core Audio APIs, it is not possible. So can I use the Registry to Enable the device or change any device to DEFAULT?On changing the default device from SOUND dialog, windows makes some changes of Binary values in registry Role:0, Role:1,ole:2under HKLMSoftwareMicrosoftWindowsCurrentVersionMMDevicesAudioCapture {GUID}.

View 5 RepliesI have a VB Web Site project that has recently (and mysteriously) stopped importing the "System" namespace by default.
I'm having to either place an Imports System line at the top of each code behind, or preface everything with System, which is fairly annoying, not to mention redundant. I can't for the life of me figure out how to get the System namespace back to being imported by default.
I've already checked to see that WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGweb.config contains the <add namespace="System"/> line--it does. That was my best lead.
I have references to several namespaces within the System namespace in the <assemblies> node (e.g. System.Design, System.Web.Extensions of my website's web.config. There is no <namespaces> node. This has not been changed recently.

frmOdyssey is the main form, from which frmSearch is called. After the above processing, I want to go BACK to frmOdyssey to process the FilFilterGrid sub on the Grid defined on frm Odyssey. I will be assigning a new DataSource for the Grid, which will be "selected down" by the strFilter. The above code works with no issue whatsoever in "Windows Application" mode. However, if I switch to "Class Library" mode, I get
an error on the last line of the last Sub, telling me "Reference to a non-shared member requires an object reference". If I uncomment the "Dim f As New frmOdyssey" line, and change the "frmOdyssey" to "f" on the next line, the error goes away, but then the process doesn't work, because the "select down" does not happen. I don't know why, except that "logically" I don't want a "new version" of the frmOdyssey. I want to update the existing form.

View 2 RepliesI'm getting familiar now with using the Dataset Designer and how it makes for quick and easy updates and query of tables. I use to use the OleDB commands and leave the Connection String as a Global Constant so I can easily change it if the server name changes, or if we have to re-direct the .NET to another instance of the database.
But now that I use the Dataset designer I'm concerned that I maintain flexibility and support in the long run. how the Dataset designer works and where it stores it's connection string info? And how difficult that would be to update. It looks like I modify the App.config file, but I'm unfamiliar with this.
What am I getting myself into? It looks like a standard XML file. Is that it?
You can change the connection string at run-time like this. You make the connection string setting available for writing as a separate property inside the MySettings class:
Partial Friend NotInheritable Class MySettings
Public WriteOnly Property RunTimeConnectionString()
Set(ByVal value)
[code]....
Then, in some place when the application is being initialized (before using any table adapters of typed datasets), write something like:
My.Settings.RunTimeConnectionString = My.Settings.ProductionConnectionString
Where ProductionConnectionString is a simple String setting. It is a User Scope setting so every user can change it (by assigning a value to it, similar to the code above) and save it by calling My.Settings.Save()This code works well for connection strings which were initially created in the main project and stored in it's settings (= app.config file).
The connection string in the app.config actually has a longer name: MyApp.MySettings.MyConnectionString.When you have a connection string stored in the app.config in a class library project, and reference that project in the main project, the app.config files will somehow be merged, so the class library has it's settings.The thing that don't know how to do, is change a setting from the class library at run-time. I could copy the connection string setting from the class library to the main project's app.config. I must keep the same name, which looks something like: MyClassLibrary.My.MySettings.MyConnectionString.Can the same principle I showed above be somehow applied to this second connection string?
