Getting Generic Currency Sign Instead Of $ In .NET Application?
Jul 27, 2011
In our VB .NET application, we use "c0" and "c2" format strings to display currency values all over the place.
Recently, users have had issues where these currency values don't show up correctly with a $ sign, but with some weird symbol, ¤. Through wikipedia, I found out it's the generic currency symbol: http://en.wikipedia.org/wiki/Currency_(typography)
I've seen the problem happen on my machine ONCE, and haven't been able to recreate it since. It went away when I restarted the application. In fact, as soon as I saw the problem, I started another instance of the application but $ signs showed up fine in that second instance.

I am writing to a Comm Port to display in a Pole Display and when I insert the � sign it displays a question mark on the customer display. Have others had similar issues when displaying currency signs and/or know how to resolve this issue?

I'm a fairly new programmer so you'll have to bear with me on this. Basically, I have a database with 3 tables, Engineers, Equipment and Signouts. I want to create a VB application that allows engineers to sign out equipment. I have all of the forms setup the way I want, and have followed a tutorial online for how to connect to the database with the MySQL .NET Connector. I have 3 forms, and have a class with all of my global variables in it. All I have managed to thus far, is define connStr as a global variable, and use it to run a connection test when the main form starts up.
My next job is to query for information about an engineer based on their ID. I have a text input box, and a button to click, and then way to display the retreived information on the next page. I have setup variables for the returned values to be put against, so they can be displayed on the form.
My question is, when the button is clicked, how do I make the application query the database based on the ID, and then use the information it returns (Engineers ID, Name and Telephone Number) to assign those values to the variables? Also, on a side note, instead of using forms, I want to use panels, is there a sub routine similar to form_load for using panels when they are shown/hidden?

I am trying to create a currency converter that will convert currency. I have a text box to enter the amount and 2 combo boxes to choose which currency you are converting from and to.
I am using a webservice site XML that contains the conversions.
The problem is I cannot get the display to work properly.

We have migrated our Vb6 application to VB.NET using a third party tool. Now we are in a process of Refactoring and introducing object oriented concepts in the application.
In VB6, we were using structures in many places. As a part of introducing object oriented programming,
1. is it a good idea of changing all Structures to Classes? or Is there a concept of "Generic Structure" similar to Generic collections, Generic classes?
2. Can some one guide me any source containing guide lines or best practices for applications that are migrated to VB.NET from VB6 and implementing object oriented programmaing.

Consider:
Public MustInherit Class Column
Public ReadOnly Property ReturnSomethingUseful() As Object
Get
'return something useful
[code]....
But this gives the following error:
Public Overrides Function ParseValue(sValue As String) As Boolean'
cannot override 'Public Overridable Function ParseValue(sValue As String) As Object'
because they differ by their return types.
I accept that you can't do this, but I'd like to be able to preserve the semantics of what I'm. trying to do, which is to have an untyped version that deals with Object, but a typed version in derived classes that knows about the specific type T.

I am trying to construct a generic interface class with generic functions. My goal was to use this to implement multiple worker classes for database interaction that have the same basic functionality. Each class will deal with different object for example, category, product or supplier but unless the the functions in the interface are generic that this won't work.This is the interface code that I have but I don't know if I have done it correctly.

I am trying to create a list of a generic type in vb.net 2.0 framework.
This is the generic type definition:
Public Class GenericParamMap(Of T)
Public Sub New(ByVal pParamName As String, ByVal pPropValue As T)
mParamName = pParamName
[Code]....
The compiler does not allow a "T" in the method's parameter because it's not defined, but I'm not sure how or where to define it. I thought it was okay to have a generic method definition.

If i have an object that implements an interface (and don't know the exact object) i can call a sub (DoSomething) by going:
vb
Dim iObj = trycast(something, iInterface)
if iObj isnot nothing then
iObj.DoSomething()
end if
How can I do this for a Generic? such as...
vb
Public Class TestClass(of T)
Public sub DoSomething()
....
end class

I recently upgraded to VB 2010 Express (from 2008), and I have a problem using the debugger. When I move the mouse pointer over an array variable, I only can get the value for the current index, and not values for all indices, as I did in 2008.
For example, if I move the pointer to classSize(i), I see the value for the current value of index i, but I do not see the plus sign which would display a drop-down list showing values of all elements in the array.
I checked for options (Tools > Options > Debugging > General), but did not see an option related to DataTips.

I'm building three web applications in .NET that will all share a users database and login information. Lets pretend that application 1 is the "parent" application and applications "A" and "B" are the "child" applications. All users have to be logged into application 1 to have access to applications A and B.
Authorization, Authentication, and MachineKey sections of all web configs are present and work correctly.
I have the correct web.config settings in all applications to achieve Single Sign On except one problem remains: what do I put in the "loginUrl" attribute of the forms tag in Applications A and B.
Assume that the url for the login to application 1 is [URL] How can I get applications A and B to send the user back to application 1 for authentication using only settings in web.config?
