IDE :: AutoUpgradeEnabled Property On OpenFileDialog1 And SaveFileDialog1

Feb 10, 2011

I am having a problem with the AutoUpgradeEnabled property on OpenFileDialog1 and SaveFileDialog1. When set to True and I call it, it works fine, but it takes 2-5 seconds to return the filename I just selected with the dialog. The Dialog box changes to a larger box than when it's set to False. If I leave the property set to False, everything works normally and the selected filename pops up immediately. What does this AutoUpgradeEnabled property mean and why does it take so long to work? (I experienced this problem with VS2005 and VS2010)

Use OpenFileDialog1 With TextFieldParser?

May 19, 2010

It seems like in order to use "TextFieldParser " you need to include the path of the file to be parsed. Is it possible to use OpenFileDialog1 and then choose a file? I keep getting error messages.

Public Class Form1

Hide / Refresh OpenFileDialog1?

Jun 2, 2009

I am running a piece of code which takes 3 secs to process and it is triggered by the clicking on the OK button on the OpenFileDialog1 box.

Everything works fine except the OpenFileDialog1 remains visible during this 3 second time period and I would prefer it to immediately hide once I click on the OK button.

I have inserted me.refresh in various locations without success but I believe this is acting on the form itself.

Any thoughts on ow to allow the box to close / refresh before the processing

.net - 'Property' Cannot Implement 'Property' Because There Is No Matching Property On Interface 'IName'?

Dec 9, 2011

I'm having some very weird issues with interfaces right now.

I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.

In my class it's like:

Private _oForm As IForm
Public Property Form As IForm Implements IContainer.Form
Set(value As IForm)

[Code]...

I have like dozens of interfaces like this working throughout my project and I can't believe this simple one can't work!

.net - If An Interface Defines A ReadOnly Property, How Can An Implementer Provide The Setter To This Property

Jun 10, 2011

Is there a way for implementers of an interface where a ReadOnly property is defined to make it a complete Read/Write Property ?

Imagine I define an interface to provide a ReadOnly Property (i.e., just a getter for a given value) :

Interface SomeInterface
'the interface only say that implementers must provide a value for reading
ReadOnly Property PublicProperty As String
End Interface

This means implementers must commit to providing a value. But I would like a given implementer to also allow setting that value. In my head, this would mean providing the Property's setter as part of the implementation, doing something like this :

Public Property PublicProperty As String Implements SomeInterface.PublicProperty
Get
Return _myProperty

Reflection - Find From A Property Info Object If That Property Has A Non Public (Private / Protected) Setter?

Aug 27, 2009

I searched on the forum / Internet for the solution how a PropetryInfo object (of a Public property) can reveal if it has a Private Protected Setter ... it was all in vain .... all help I found was about how to "Set" value of a public property having a Private Setter.I would like to know if I have a PropertyInfo object of a public property, how would I know if its Setter is Non Public?

I tried, in a exception handling block, where I did a GetValue of the PropertyInfo object and then called SetValue by setting the same value back... but to my surprise it worked well and didn error out.

Error - In Order To Evaluate An Indexed Property, The Property Must Be Qualified And The Arguments Must Be Explicitly Supplied By The User

I'm having a few problems converting some code into VB.NET from C#. Most of the translating is done, but I am getting errors when I try to run my code, and I can't figure out what is causing them. Here is the Sub I translated.

.net - Make A Class Property Behave Like The Checked Property On RadioButton?

Jun 1, 2012

I 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.

C# - Why Is Attached Property Property Changed Event Only Firing One Time

Nov 27, 2010

I have a listbox binded to a list of objects. For each list item I wanted to have a rectangle whose fill color is determined by a few properties of the binded object. So I did the following:

Made sure INotifyPropertyChanged was implemented on my object.Created a class to expose the properties I am interested in as attached properties.Binded the properties of the object to the attached properties of the rectangle Created a style that uses triggers to set the rectangle fill based on attached properties.

This works, but only the first time the property of the object changes. After that, the attached properties do not seem to be receiving notification when the data object's property changes. I have double checked and my data object is raising the INotifyPropertyChanged event.

<Rectangle Style="{StaticResource RecordStateRectangleStyle}"
Width="10" Height="10" Stroke="Black"
local:RecordAttachment.RecordState="{Binding Path=RecordState}"
local:RecordAttachment.IsDeleted="{Binding Path=IsDeleted}" />

IDE :: VisualStudio Property Toolbox Not Remembering Last Selected Property Item

Sep 1, 2011

I have a weird question and I honestly hope you understand what is happening here: I design my form (using VB.NET) and put on it a few textboxes, comboboxes and a listview. After the design, I want to adjust the TabIndexes for each control on the form. On the right-hand side of the interface is the property box.

I then select the 'TabIndex' property item and enter a number key (for instance 0) for that selected item. I then select the next textbox control and enter the next number (for instance 1) WITHOUT re-selecting the 'TabIndex' property item. As soon as I select the combobox or listview control, the currently selected property item jumps to 'Items' or 'Collections' and does NOT remain on the 'TabIndex' property item. Why is this happening? Everything worked fine and all of a sudden this starts happening. Should I reset the editor settings or how can I resolve this matter?

VS 2008 - Property Grid - Click On Item Show Its Property

Mar 18, 2009

I have a listbox with several list items added. I want that as user click on an item, I should be able to show its property. This should change for different items. For example (hypothetical) : Listbox has numbers 1 - 10. Now when I select 1 I should be able to set property - Name, Lastname, Colour, Age.

When I select 2 I should be able to set - Age, Hair Colour (clr shows), Weight, Date. When I select 3 then - City (combo box drop down), Country, Age only. This way value changes for diff items. One way is to put them in property grid and show them. Though this looks nice but adding/removing items in that is not easy. You need to have a class that refer that to prop grid. Do I have to code for each classes for all values in listbox or is there an easier way to manage items in property grid. If you think prop grid is not the right tool for such an activity then can you suggest something else.

IDE Stop Filling In The Rest Of A Property When Creating A New Property?

Nov 5, 2011

when I'm creating a new property in Visual Basic .NET in Visual Studio 2010, the rest of the Property (template?) doesn't complete the basic framework of the property in the code editor. It is now treating a statement like:

Public Property Length() As Integer

Instead of completing the property as it used to (code follows), it simply goes to the next line:

Public Property Length() As Integer
Get[code].....

What happens now is that, if I type in the 'End Property' code, the name of the property will now be highlighted as an error since it doesn't have a 'Get' or 'Set' portion.However, when I THEN type the 'Get' on the line following the 'Public Property Length() As Integer', then the balance of the property is created in the code automatically.I don't know how this got changed, but would love to change it back.Does anyone know if there's a setting in VS2010 that addresses this, or if it's something with the basic templates that visual studio uses for creating the basic code components?The weird thing is that for everything else, from class declarations, structures, functions and subs, the IDE still creates the balance of the code structure correctly. The only area where it doesn't is for Property declarations.
