Show The Error Provider Properties To Property Grid At Runtime?
Feb 23, 2011
In designer i had a button with errorprovider.The button show 3 extra properties at button's property grid in design time.Error on ErrorProvider1
IconAlignmnent on
IconPadding on
But how can i show this 3 extra properties in propertygrid at run time?
Private Sub Form_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim propertyGrid1 As New PropertyGrid()
propertyGrid1.CommandsVisibleIfAvailable = True[code].....
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.
vb Public Class clsTest Public Property Test1 as string '...

how can i make it so when i show clsTest's properties in a propertygrid it has the ability to expand clssettings properties? (kind of how font does it on a text box for example)
I have a custom class (Class1) with a bunch of properties. One of the properties of this class is another custom class (Class2) with its own properties.I have a property grid with the selected object set to Class 1. I can see Class 2 as a property, but i would like to expand Class 2 to show its properties in the same property grid.
Im basically trying to do the exact same thing as the Font Class on a form. If you look at the properties of a form in the designer, you can see the font property. You can then expand that to show the properties of the font class.
I'm creating a UserControl that draws a simple radial gauge. I need it to be very customizable; the user should be able to customize everything such as the colors, fonts, sizes. So, I just made a property for every customizable detail. For example, I had ScaleFont, ScaleColor, ScaleStart, ScaleEnd, ScaleInnerRadius, ScaleOuterRadius, ScaleTickmarkFrequenty, etc.. etc.. etc...
Because there are so many properties about the same subject, I wanted to 'group' these properties into one "property". I've seen this done loads of times in third party controls, but I've never done it before myself.The idea is that the properties can be accessed like
So far, I tried creating a class for each group, for example a clsScaleSettings class, containing properties like Font, Color, Start, End, InnerRadius, OuterRadius, TickmarkFrequenty, etc (corresponding to the same properties as above).
Then, for every 'group' or class, I create a Property. For example, I have the ScaleSettings property, which simply returns an instance of the clsScaleSettings class (I initialize the instance only once of course):
vb.net Private _ScaleSettings As New clsScaleSettings Public Property ScaleSettings() As clsScaleSettings
[code]....
Now, this works in the code editor. I can now use
Gauge1.ScaleSettings.Font = Me.Font
for example, and it sets the font correctly.But, I does not work in the designer, in the Property Grid. The whole reason I made the effort to move and rename nearly all properties (about 70!), and all references to those properties, to separate classes, was so that the user could design the gauge more easily using the Property Grid!Instead of having 15 settings related to the scale, scattered all over the Property Grid, he can now have one ScaleSettings property, which he can expand, and then he can edit the properties of that group easily.The ScaleSettings property is greyed out in the property grid... So I cannot expand it and view it's underlying properties.
start with I was given a program by a friend that was created in Excel 2003 with the help of Visual Basic Editor. He said he used Visual Basic 2003, which he is not 100% sure about. Anyways he used CurLine in the program and when I try to open it in Excel 2007 and then open the Visual Basic Editor and run the program I get the following error:Run-time error '-2147418113 (8000ffff)':Could not get the CurLine property. Unexpected call to method or property access.
i have 2 computers - a Server and a Client pc which is running on local area network with MICROSOFT SQL SERVER 2008 R2 Developer kit at the main pc and Client computer will need to connect to SQL SERVER at main pc using connection string.Let me named server computer as 'MAGNA-PC' and the client pc as 'LAC-PC' and database name is 'db_referafriend' so the code for MAGNA-PC(server) connection string is:[code] i GOOGLE and YOUTUBE for almost 2 weeks before i post . I know that i need to configure the sql configuration manager and enable tcp/ip also add a new port at firewall to allow remote connection also add the sqlserver.exe and sqlbrowser in firewall and I have also chosen "Using both TCP/IP and named pipes" under Remote Connections in the SQL Server 2005 Surface Area Configuration. and all of this doesnt work!
A VB5 program I wrote years ago stopped working and is now giving me this error:
Run-time error '380':Invalid property value
I cannot figure out what has changed, since I run that program almost daily. It was working fine, then stopped (without any changes to the program). I suspect I may have uninstalled something it uses, but cannot figure out what.When I open the VB5 IDE, I get an error saying:
'c:program filesdevstudiovbComct232.ocx' could not be loaded--Continue Loading Project?
If I say no, it does not load and I cannot see the source code.If I say yes, it does load and I can see the source code but I get weird compiler errors.
I'm making a control and I am trying to finalize my design time properties grid. I have several List(of Class) items as public properties and when I click on the design time menu (while testing the control) there is the word "Collection" and a button with an ellipsis (...) that brings up a neat pop up with the buttons Add/remove and all of the public properties of the collection's class on the right hand side. Basically for a non-collection instance of a class (with public properties) I'd like a similar button to show up. I know I could put all of the properties in the main control class and group them, but I like the pop up box feature. Anyway to duplicate this? (think font grid item etc.)
my error code is run-time error 1004 unable to get the correl property of the worksheetfunction class. I read the data from xlsx-files to one dimensional arrays in my vb - program. the essencial code parts are
Option Explicit Option Base 1 Dim winvyf() As Double, winvx() As Double
As I understood , The property grid is given an object which it can manipulate by extracting its Properties using reflections.
My problem is that I have a set of Parameters that is determined during run-time , thus I can't staticly compose a class with properties to represent this set.
I have two idea in mind to solve this problem but both are complex and will probably consume lot of time , infact i will say they are not practical under my time constraints. One is to use Reflection Emit in order to define a class dynamically and the other is to dynamiclly build a C# source file and then compile it using CodeDom.
Can Property grid behave in a different manner( other then extracting the Properties of an object using reflections ) that can suite my problem?
I want to say that the reason I went to the property grid from the begining was its ability to provide realy nice Data Retrieval UI for common types.For color you autometically get a palette , For dataTime you automatically have a nice calender. I would like to get those things automatically If possible.
I'm working on a Hazardous Materials label printing program. One of the options is to do an "NFPA" label. Since there are 4 values required with 4 or 6 options, the ratings are entered via radio buttons in a group box. That's working okay. I display values in the NFPA diamond as they're entered: left quadrant blue, top quadrant red, left yellow, bottom red. I'm having trouble with the label in which the rating will be displayed on top of a jpg diamond for the white. In this quadrant the text can be up to 4 characters. I can accept the text going into an adjacent block a little, but the corners of the label overlap into another quadrant/color. I reduced the font size which solved the overlap problem but the font is then too small and looks terrible. I tried to make the background of the label transparent to let the color come through correctly but that's not a valid value for label.background. I'm figuring that the transparent background is the best solution. What can I use that will accept a transparent background so the color shows through?
I'm trying to set the transparent property via label properties properties, not via code. Here's the code if it makes any difference:
Public Class NFPA Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Close() End Sub
I have the following property in a property grid in VB.Net 2010.

I need to make this property a list box that gets the values from a database table and populates the list box with the values from the table. I have tried numerous things to no avail.
I have my own class of graphic objects, and now I'd like to allow a user to right-click on one of those within the application and see a properties window. Is there a pre-built dialog or control for displaying properties at runtime? I'd like to have something just like the IDE properties window button for my application.
We are working on a media center plugin to show internet tv from a local provider. They are distributing their metadata as this link[URL]..It seems to be an xml list of rss feeds, because if I open the links in internet explorer, I get a nice html page.
My task in this project, is to write an aggregator that read the xml feeds, convert this into collections of metadata objects, that will be used to build the menu in media center. These will be simple List of... objects with categories, synopsis etc.
What is the best way in .NET to make this happen. It isn't even pure xml but rss feeds and I have never worked wit this. Can I benefit from technologies like xsd schemas, LINQ etc to make my job easier?
I used error provider tool to display the error when the textbox is empty. when the error message is displayed immediately it is inserting the record into the database.I want to clear the error and then insert. how to take the control to textbox?

I've reviewed the links that were offered and don't find an answer. Neither has a lot of searching helped, probably because I can't think of a reasonably short way to ask the question. I hope that I've at least found the proper forum and category.
In my VB 2010 code, I've defined a structure that has about 30 elements. I want to sum the properties (they are all singles) of two members of the corresponding collection. I understand that I can do something like:
member1.property1=member2.property1+member 3.property1 for the entire set of properties of member2 and member3 to produce a completely defined member1 What I wonder is whether or not there is a way that uses fewer lines of code - I know that I can't do:member1=member2+member3, for example.
When I run the code, type a value in quantity and hit the calculate button I get an error message stating, "Quantity must be a numeric value" and I don't see in the code what I have missed. I thought I set quantity as a numeric value by making it an integer and parsing it.
Private Sub calculateButton_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles calculateButton.Click ' Calculate subtotal Dim subtotalDecimal, amountDueDecimal, shippingDecimal As Decimal
My problem is similar to the one described in this article, but I'm trying to use a different grid (DevExpress.xtraGrid) and therefore the answer (if it even works) does not apply for me: [URL]
Briefly, I'm binding the grid to the collection of custom objects - cMessage - to grid's datasource, but I don't want all the propertieties of the cMessage to be shown in the grid. Is there any way to hide some properties from the binding, while leaving them acessible from outside (ie.leave them as public or friend)?
My program in VB.net has been using in 4 years already. I coded it in my computer and run in other computer. It's modified several times and it still woked fine. Today, I modified it again. It works well in my computer, but when I run it in other computers, I got an error:
" Failed to decrypt using provider 'RsaProtedtedConfigurationProvider'. Error messsage from the provider: Bad Data."
I created a DataGridView called grid_LivingBenefits.Each time a cell is going to be edited, the program will validate that cell.Now, I have two subroutines that take care of that validation.these are: ValidateDataType() and ValidatePrimaryKey()
at the DataGridView CellBeginEdit, the program checks for which cell the user is editing.at the DatagridView CellEndEdit, the program calls the subroutines for validation. If an input is invalid, I want the program to show an errorProvider on that cell.I used MessageBoxes first to check whether the validations are working and I got no problem there. but when I tried to use errorprovider instead of a messagebox, there's a blue zigzag line under the grid_LivingBenefits.CurrentCell
Dim objConnection As New SqlConnection(Application("ConnString"))
My connection string is: [Code]. I googled this problem and the solution for it was having a malformed connection string where the "provider" was being specified when it shouldn't have. Example conn string: [Code]. I'm not specifying the Provider so I think I have a different problem.
I have a Visual Basic 2005 program which runs fine if I execute the built Executable. However if I start the application in VS2005 debugger it gives a weird error
First attempt at using the error provider, I've set this up for each of the five text boxes I have on my form, when I click the button it shows the error provider flashing between the various boxes if I leave them all empty. Ideally I'd like the form to show the symbol next to the box thats empty, click the button and remove it from those which are correct leaving only the incorrect text boxes with the symbols. Any thoughts? [Code]
When im using a loop in my program and i'm trying to use an Error Provider to pop up whenever a textbox in my groupbox is empty for some reason I cannot get it to work, can anyone tell me what i'm doing wrong?
For Each ctrl As Control In GroupBox1.Controls
If TypeOf ctrl Is TextBox Then If CType(ctrl, TextBox).Text = "" Then
[CODE].............
I'm not receiving any type of error, it's just that when a textbox is blank the error provider is not doing anything.
i have a picture box which in this case is my button , when i press my button(picbox) i want it to check if the error provider has got any errors and if it hasn't any errors i want it to start timer2. when i press it i get errors with the provider and after some seconds the timer2 starts.
