.net - EventArgs(Of T) Gets Marked As Not CLS-Compliant?
Feb 17, 2010I wrote a generic EventArgs class in my VB.NET solution:
Public Class EventArgs(Of T)
Inherits EventArgs
Private _eventData As T
[code].....
When I use it as in the following example, it says that e is not CLS-compliant.
Event MarketModeChanged(ByVal sender As Object, ByVal e As EventArgs(Of Integer))
Practical Limitations With Assemblies Not Marked As CLS Compliant?
Mar 21, 2012As an OSS library author, I've always tried to make my stuff CLS compliant. But MS doesn't make this easy. They often put you in catch-22 situations, such as the following:You cannot have a protected variable differing only in case from the public property.You cannot have protected or public variables starting in an underscore or 'm_'. If you want to make a class really extensible, you often need to have protected variables matching public properties. Your least ugly exit is to add a suffix to the variable, like "Var" or "Value". That's nasty and unacceptable to me. I like clean code.I know of no .NET languages that don't support variables starting in an underscore, and I've used them in many places where the variable needs to be visible to subclasses.
I'm tired of the warnings, and I'm planning on turning off CLS compliance at the assembly level on my 30+ C# libraries.Are there any actual problems with turning off CLS compliance on libraries? Any real problems with doing this? Microsoft has issued unheedable guidance on software for decades, with less that 5% of it being worth the bytes it was encoded in. I can't find any evidence that this best practice has any real effect on anything. But, to be careful, I'm checking. And no, this is not a duplicate of the inverse of this question: Any reason not to mark a DLL as CLSCompliant?I'm looking for actual results and effects here, not the advice of a MS intern. For example, if IronPython, IronRuby, or F# are unable to read or write a variable starting with an underscore, that's an effect, although it would only cause a problem for users subclassing certain objects. If a language or tool is completely unable to use an assembly unless it is marked CLS compliant, now that's a big deal.
Can Input A ISBN With A Missing Digit Marked By '?'
Feb 11, 2010I can get it to tell me if the ISBN I entered is valid or not, but there is a second part I need that I keep drawing blanks on. I need to be able to enter an ISBN with a missing digit marked by a "?" in the textbox i am entering the ISBN in. For those who don't know what an ISBN is it...
An ISBN (International Standard Book Number) is a ten digit code which uniquely identifies a book. The first nine digits represent the book and the last digit is used to make sure the ISBN is correct. To verify an ISBN you calculate 10 times the first digit, plus 9 times the second digit, plus 8 times the third ... all the way until you add 1 times the last digit. If the final number leaves no remainder when divided by 11 the code is a valid ISBN.
1.Write a program that reads a ten digit number and validates it.(DONE)
2.Write a program that reads in a valid ISBN with a single missing digit, marked with a ?, and outputs the correct value for the missing digit.(Ehhh....)[code]So i need help making it so i can input a ISBN with a missing digit marked by "?" and output a valid ISBN with missing digit.
EntityDataSource Null Update Parameters Not Getting Marked
Feb 24, 2011I am using an EntityDataSource with a FormView on VB.NET application. The FormView contains an AjaxControlToolKit TabContains with multiple tabs. Due to the fact that each tab is a naming container, Bind doesn't work properly for updating values (as discovered from reading other posts on stackoverflow). I instead have to declare UpdateParameters on my EntityDataSource.
Example markup is as follows:
<asp:FormView ID="fv" runat="server" DataSourceID="eds" DataKeyNames="ID">
<EditItemTemplate>
<asp:TabContainer ID="tc" runat="server">
<asp:TabPanel ID="tp" runat="server" HeaderText="Tab 1">
<ContentTemplate>
[Code].....
This works great, until a customer is edited and their name is set to nothing (assuming in this case, a null name is allowed). The Name UpdateParameter is set to Null but the ObjectStateEntry is not set to modified for Null properties, even if previously the Entity had a value specified. As long as the name is changed to something other than Null, everything is updated correctly. I found a workaround by putting the following code in the Updating event of the EntityDataSource.
Dim ose As ObjectStateEntry = context.ObjectStateManager.GetObjectStateEntry(action)
For Each p As Parameter In eds.UpdateParameters
ose.SetModifiedProperty(p.Name)
Next
This makes sure that each property in the UpdateParameters has its state set to modified. It works, but it seems like a hack and I can see it causing problems down the road. Is there anything else I could do?

C# - Why Are Many Designer Classes In System.Design Marked As Internal
Aug 28, 2009I have been developing some components for our products at work, and one of them is based off the flow layout panel.What i would like to do is provide a custom designer for it, but without loosing the features provided by it's default designer (System.Windows.Forms.Design.FlowLayoutPanelDesigner) which is marked as internal.Using Reflector i thought i would just implement it again myself, seeing as it inherits from 'FlowPanelDesigner and that from PanelDesigner` all of which are internal.
Why would these classes be specifically marked as internal? Is it due to them being specifically for Visual Studio use, and thus not 'framework' code?Also, is there an easier option that re-implementing all the functionality?

Mouse.Click And Mouse.MouseDown - Delay The Mouse Down Event

View 6 RepliesVB2010: Resource Files Are Being Marked In The Error List As Not Valid Win32 Apps
Feb 6, 2010I have an application that is primarily developed on an x86 machine. I recently checked the app out of TFS onto a Win 7 x64 machine for development. However, every single form level resource file shows up in the error list with an entry like the following:
is not a valid Win32 application. (Exception from HRESULT: 0x800700C1) Line 127, position 5. C:Users...shortened...FormsfrmCustomer.resx Line 127 Column 5
What I find interesting is that my application level resource files aren't showing the same error. Plus, these are just XML files. They aren't applications in any way.
I'm currently working under VB2010 beta 2 on both machines. Obviously, with a bunch of errors, the app won't compile on the x64 machine.

Custom Control Error "not Marked As Serializable"
Sep 8, 2010The problem is, having converted from VS 2002 to VS 2008 the designer can't seem to handle the custom controls on "my" (not original designer) app. Any time I try to copy, in particular, the custom derived comboBox control I get this error initially:
Type 'Corporate.Controls.data.comboBox+comboBoxDataSource+Item' in Assembly Corporate.Controls, ... is not marked as serializable.
I chased this error down, marking classes Serializable and private variables therein as NonSerialized when they caused a problem (which might or might not be the smartest way to attack this problem...) but I've hit a brick wall. The most base corporate derived ComboBox class is:
Namespace Corporate.Controls
Public Class comboBox
Inherits System.Windows.Forms.ComboBox
...
End Class
It's unrealistic to post all of the relevant code (I believe). The short of it is:
System.Windows.Forms.ComboBox <- Corporate.Controls.comboBox <- Corporate.Controls.data.comboBox
I just kept backtracking through the errors.At this point I can't set System.Windows.Forms.ComboBox to Serializable. I've tried marking the Inherits System.Windows.Forms.ComboBox clause with <NonSerialized()> and while that doesn't cause a build error it doesn't seem to fix the designer-generated error in the other libraries when I go to actually add, copy or even delete the control in WYSIWYG. And that is the only reference to System.Windows.Forms.ComboBox in that (or any other) corporate library.
