View 1 RepliesI have a Class Library project with a appSettings.config file included into the project. The file is not embedded. So I have a ClassLibrary.dll with a appSettings.config beside in the bin.I have another project which is a Web Service. It has a reference on ClassLibrary.dll with a Copy Local=true. When I build the Web Service, the ClassLibrary.dll is brought into the bin of the Web Service. However, the .config doesn't follow.Do I need to do some postbuild event to copy the .config file or there is another setting I can set?
View 3 RepliesI have a very simple class that holds a few public properties - ID, Text, Colour, etc. and a Boolean called 'SelectedItem'. Just like the Checked property on RadioButtons, only one item can have its SelectedItem property set to True within a particular group. Note: there will be several separate groups (lists), each allowed to have only one item with SelectedItem = True.
My first thought was that I would probably just have to handle everything outside of the class, setting SelectedItem to False for every other item in a particular list when another item was selected. But that seems rather inelegant to me. So I've been trying to think of how this might be done within the class. For example: could I perhaps have a private string property called say "GroupName" - set in the New sub when adding a new instance of the class - and then use a private shared method to set every item's SelectedItem property to False, provided the item has the same GroupName as the newly selected item? I would have a go at doing this but I have no idea how to enumerate every instance of a class from within that class, or whether that's even possible. Is it? Or is there another (better) way to achieve my goal? Here is a cut-down version of what I've got so far:
Public Class ResourceItem
Public ID As Integer
Public Text As String[code]....
As can be seen: instead of instantiating a new ResourceItem and passing that as an argument to the manager's Add procedure, I'm simply passing the details of the new item and the procedure is creating the item from those. I don't know whether this is a good or bad idea - please advise - but I've done it because I couldn't figure out how to make the SelectedItem property only writeable by the manager, so I wanted to avoid having directly accessible objects that could have their SelectedItem property set to True without it deselecting all the other items in the same group. Of course that still leaves the possibility of setting a variable to one of the manager's list items and setting it from there, so I would still like to know how I could prevent that, if possible.
UPDATE: I didn't use the code above in the end, deciding instead to go with Cyborgx37's solution - which seems to work perfectly well for me despite the warnings about best practice. I also realised I would need to use the same class in another scenario where multiple items could be selected, so it was easy to add a Boolean property to the manager to enable that.
I have the following code:
Public Class MyColorsClass
'Constructors
Public Sub New()
'Empty Constructor
[code]....
However, if the empty constructor was called to instatiate this class then the colortype is not yet set. Therefore, if one accesses the 'IsColorCool' property it will always return 'False'. Now for the sake of this example, I must keep the empty constructor as part of the class.Now I could add some code in the 'IsPropertyCool' to check and see if a ColorType has been defined, and throw an exception if it has not been set, but I don't really want to do that.I also could always move the logic OUT of the property and into a method on the class called 'DefineIfColorIsCool' or something, and make the owness on the caller to make sure the method was called if they want to use the property 'IsColorCool'?
Supose a base class
Public Class airplane
Private var_num_seats As Integer
Private var_num_engines As Integer
[code]....
Obviously, I don't wish that the class Glider has the method "start_engines" neither the property "num_engines". Otherwise, other child classes may have. How can I supress these property and method in child class, not just ignoring (if I can)?
I have procedure (Import) that calls a for a new instance of frmImportData. I also have a class name clsBatch that has a data table property called prpParametersTable.For some reason, I get an error (indicated below with ERROR>>>) when trying to assign prpParameterTable to cv_dtImport2. The error states "Object reference not set to an instance of an object.". Why does this error not happen when I assign dtBP to cv_dtImport1? Both cv_dtImport1 and cv_dtImport2 are equal to Nothing and in my Import procedure dtBP = prpParametersTable.
Public Sub Import(ByVal clsB As clsBatch)
Try
Me.cv_clsB = clsB

I have three class files, accounts.vb and transactions.vb in addition to my form.vb. I am unable to retrieve a member variable from on class from inside the other. When the combobox index changes, the program loads the correct account (checking or saving) from two different sequential files. I don't think I have the calcBalance procedure in the correct class file. And that is what I am having trouble with. Accessing it to display it. [Code]

View 9 RepliesI have several asp.net website projects for various sites.Currently I want to add REST API's to these projects so I can start developing mobile apps (using HTML5/JavaScript/CSS3 and PhoneGap) that make use of these webservices.
Since WCF is far more powerful than regular asp.net webservices (among others with control over the service and authentication/authorization), I'd love to add these to my existing website project.
I did a Google search but cant find anywhere a step-by-step tutorial how this can be done. And also if there's any functionality I'd possibly loose when adding WCF functionality.I was also thinking of creating a new project specifically for WCF, but think I'd rather add it to an existing website project.

I have inherited a large VB.NET solution that was created in VS 2003. I am trying to update it to VS 2008 to maintain it. I no longer have access to an install of VS 2003.
The solution contains 15 projects that are console applications and 1 that is a Website application. The website application refers to some assemblies in the other console projects.
When I try to open the solution in VS 2008 all the console applications open but as it tried to open the Web application (or website? -- not sure) I see the dialog "Trying to open http://dmedibiz/dotcom.vbproj". It is unsuccessful in doing so. I don't have a website named http://dmedibiz on my development machine.
I tried changing the name of the website in DotCom.vbproj.webinfo, but that does not have any effect in VS 2008. When I go so far as to change the Hosts file so that the local machine resolves "dmedibiz" to the proper folder on my local machine, I keep getting prompted for a login and cannot access the folder even using the administrator login. I have tried adjusting the security on the Folder and in IIS Manager and even in the Frontpage Extensions, but nothing works.
So, what can I do to open this web project along with the other projects whose classes it references? Is there a way to change the website reference in the upgraded application? I actually do not want Frontpage Extensions in the site, but there was some reference to that also in the erro messages about installing them to "fix" the problem.
Here is the error I am receiving...
Unable to open the Web site '[URL]. Could not find a Web server at 'http://dmedibiz'. check to make sure that the Web server name is valid ...'
Can anyone tell me how to change the website location reference? Or must I remove the Web project from the solution and create a new Website and then copy in the files that need to be worked on?
confirm the forum for this question about Visual Web Developer 2010 Express. I found a VWD Express forum, but it was in Spanish... Lo Siento. My issue is selecting a down-level, 3.5, framework version as I create a new project/website. I have figured out how to CHANGE the target framework version once the website/project is created. I have the 3.5x installed on the system and available. The articles I have seen discussing this issue, refer to a framework version selection drop list in the new project creation dialog/wizard. I do not have that option.

Can anyone suggest something like a: Checklist or Must Do list to achieve this?PS: I have had a problem trying to move the project from one server to the other, the project seems to look for the dlls of the AJAX control and the textBox counter where i originally unzipped the folders in which they cam in, which i think was on my desktop, although when i added those controls to the Tools tab, i created a new tab, then i choose the dll from the where i unzipped the controls source code, aint that enough?
I have two classes, and for a property in one of the classes I'd like to be able to load it up with an array of the other class. However my attempt at accomplishing this results in a "Object reference not set to an instance of an object" error. I know it's a rookie mistake, but I'm stumpedssist?

Public Class ScaryAnimal
Inherits Animal
Public iScariness as int32 ' 0-100, how scary is it?
End Class
Now, if I have an instance of "Animal" with some values in it, and I decide I want to cast it to a ScaryAnimal for some reason, how do I do that without having to create a new instance of "ScaryAnimal" and copy each property value?Basically I'm looking for a way to do this, without having to write the lines marked with '*** below:
