Setting Control Properties In Designer
May 1, 2009
I've played around with this and have figured most of it on how to set the properties of most controls in the designer. I have 2 check boxes I need to set the values on but do not know how. 2 fields one for each in the db with a char(1) value, can be Y or N. If it a Y in the db how would I set it as checked on the form?
'cboPosition
Me.cboPosition.DataBindings.Add(New System.Windows.Forms.Binding("SelectedValue", Me.FmfieldmanmasterBindingSource1, "position_name", True))
Me.cboPosition.DataBindings.Add(New System.Windows.Forms.Binding("Text", Me.FmfieldmanmasterBindingSource1, "position_name", True))

Is it possible to make a form that can set the properties on a custom control in the designer? What I mean is I want to know if it is possible to show a dialog that allows you to set the settings for a certain property like if you were adding items to a listbox.

How do I set a User control (or a class with a few properties) to appear in the tan bar at the bottom of the Designer? I have tried googleing it but, I don't know what that bar is called (Kinda Hard to Google without know what to Google)

The company has a Visual Studio 2010 Ultimate project that is written in Visual Basic. The project has several strings in the resources file (Resources.resx). One of those strings (VersionSuffix) contains "" when we are distributing a normal version of our product and "BETA" when we are distributing a beta version of our product. Most of the time we distribute a normal version of our product. Therefore, most of the time the resource string VersionSuffix contains "".
Recently, we attempted to distribute a beta version of our product. Therefore, we changed resource string VersionSuffix from "" to "BETA". However, it quickly became apparent that the resource string VersionSuffix was being used as the default value for several control properties in the form designer. For example, if I draw a rich textbox on a form then file FORMNAME.Designer.vb will contain the following.
Me.RichTextBox1.Location = New System.Drawing.Point(286, 306)
Me.RichTextBox1.Name = "RichTextBox1"
Me.RichTextBox1.Size = New System.Drawing.Size(134, 33)
Me.RichTextBox1.TabIndex = 32
Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix
We are unable to find anything anywhere that indicates that this resource string should be used as the default value for control properties. Therefore, we have no idea why this resource string is being used for this purpose. We would like to change the control property assignments in the designer from Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix
Me.RichTextBox1.Text = "" However, we don't know why these strange assignments are being made. Therefore, as soon as someone adds another control the problem will most likely return. Does anyone know why this is happening and how to prevent it from happening again?

I am attempting to update an existing winforms application, that was created with a dataset control on all the winforms pages. I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?

I am trying to change some properties with a property page during design time. The properties get set okay and the form updates (graphically) and the new properties appear in the property list, however they do not get written to the designer. If I close the form I am on and then reopen it the changes have been purged. However, if after I make a change with my property page, I manually change anything on the form, then it knows it is dirty and commits the changes to the designer.

I have a base form class that is providing a new property that looks Like this
Public Class BaseForm
Private _HappyTime As Boolean
Public Property HappyTime() As Boolean
[Code]....
Now when I inherit the BaseForm on a new form, the HappyTime property displays in the properties window as false, and is uneditable.
I've recreated this BaseForm and Inheriting Form in an entirely new soloution and, the HappyTime property is editable and works as expected. For some reason in the existing project (where these changes need to be made) it's not behaving properly.

I have a very simple setup, single mycontrol.ascx with assoicated mycontrol.ascx.designer.vb and mycontrol.ascx.vb file.
mycontrol.ascx embeds a single reference to a custom control: "MyMenu":
<mM:myMenu id="myMenu1" runat="server" />
This has created a protected reference in the mycontrol.ascx.designer.vb file:
Protected WithEvents myMenu1 As Global.CustomControls.MyMenu
Now, when I breakpoint the Page_Load() event of mycontrol.ascx, and inspect the members returned from the type via:
Me.GetType().GetMembers()
I cannot any reference to myMenu1. If I look at the control with intellisence, the property is accessible:
Me.myMenu1
what I'm missing and what I need to do to access designer created properties at runtime through reflection?

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
Me.Gauge1.ScaleSettings.Start = 10
Me.Gauge1.ScaleSettings.End = 80
...
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.

I am creating a UserControl with rich design-time support that should eventually look like the Options window in Visual Studio (or many other applications). Basically a split container, to the left is a TreeView with 'option categories', and each node in the treeview corresponds to a 'panel' to the right with certain options.
Just for terminology, the nodes in the TreeView are OptionsNode objects, the panels (containing the controls that determine the options) are OptionsPanel controls. My UserControl itself is called OptionsView and is the control that contains the treeview as well as a panel that contains the OptionsPanels.
I have some experience in design-time coding, and I have gotten pretty far. The OptionsView control contains a property Panels that returns the ControlCollection of the right side of the split container. The user can add/remove OptionsPanels via this property (and automatically an OptionsNode is created). The property uses a custom CollectionEditor that tells the designer to create instances of type OptionsPanel (instead of just Control which is the usual collection type of ControlCollection). Furthermore, in the CreateInstance method I use the DesignerHost object and its CreateComponent method to create the panels, instead of just creating New OptionsPanel objects. This way the OptionsPanel created is selectable and editable (via property grid) during design-time:
vb.net
Protected Overrides Function CreateInstance(ByVal itemType As System.Type) As Object
If itemType Is GetType(OptionsPanel) Then

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.)

In the SignalR Chat sample, Caller properties are set using the code;
Caller.name = newUser.Name;
Then later on, this property is read;
string name = Caller.name;
I have my own SignalR project, but this one is vb.net, and when i do the same setting and getting of the Caller properties, it doesn't work

I'm stuck trying to figure this one out. I am trying to set a GridViews Column properties by using reflection and the Extended properties off a DataTable.the Code looks something like this
Dim colproperty As PropertyInfo = gv.Columns(col.Ordinal).GetType.GetProperty(key)
Where key = "ItemStyle"
So I get the ItemStyle Property by I'm unsure how to set the next varibel which would be BackColor:Red in the collection i have that key access. This is all text.in the XML the extendedproperty is set like this
msprop:ItemStyle="BackColor:Red"
I can easily set all of the attribues for a gridview using something simular to this but of course gridview columns do not have attributes only properties.
Gridview attribute setting code
Dim nvCollection As PropertyCollection = table.ExtendedProperties
For Each key As String In nvCollection.Keys()
Dim colproperty As PropertyInfo = labelOut.GetType().GetProperty(key)

is there any trick (because I can't think of anything else ! ) to massively set all of the properties , of a user defined class , to their null values ? You see , I have a class called Apartment and it has a lot of properties (it only has properties , no methods or events , if that's important) and those properties are either strings , doubles or integers . I want each time I create a new instance of that class (a new apartment , that is) to automatically set those properties to their null values . That is all of the strings to be equal to "" and all of the numbers to be equal to 0 . Back in VB6 I could rely on VB6 to do this automatically , but now in VB .NET , whenever I create a new instance of a class , all the properties start with the value = Nothing . I know I can define every property in the class module like that : Public MyVariable As String = "" but I'd like to keep them as they are and set their null values directly whenever a new object of that class is created .

Most of the apps I write have a base / home form and a few other forms (three of four typically) which pop up in response to controls clicked by the user. I'd like to be able to set some properties to be the same for all the forms in an app; particularly properties like BackColor and FormBorderStyle. Yes, I can manually set the individual properties for each form in the VB IDE, but I'd prefer to be able to have one line of code in the base / home form for each property along with one line for each dependent form which says something to the effect of "use the same property value as the base / home form has". Overall, my objective would be to have one single line of code in the app which, when changed, would apply the changed property to all the forms. For example, a single line which I can change to take the BackColor from Apple to Orange for all the forms ...

In VB6 I would simply retrieve the user font setting from the .ini file, load into variables and then apply to the appropriate control.
text1.fontbold = userfontbold
text1.fontitalic = userfontitalic
text1.fontunderline = userfontunderline
etc.
I'm struggling to understand how to do this vb.net The following code works, but sets all three at one time
Text1.Font = New Font("Courier", 10, FontStyle.Bold Or FontStyle.Italic Or FontStyle.Underline)Since the user can have many different combinations of settings, I would like to be able to add just one of these properties at a time, but can't seem to figure out how to do it.

I have a icon for my application that I set in the project properties window there is a little drop down box to browse to the icon location. While debugging everything is good. Once I build the app and place it on a PC and manually start the app all is good. My app starts with windows and now every time the program goes to start I get an error that the icon cannot be found in the DocumentandSettingUSERNAME folder. So the question is do I have to place my app icon in this folder? In design I have the icon in the binDebug folder and that is were I point to in the Project properties page.

i am writing a VB front end (VS 2008 .NET 3.5) to a data loading program that involves moving the contents of CSV flat files into SQL Server 2005 staging tables. I have had some experience with DTS in SQL 2000 so I decided to use SSIS packages to load the CSV data. Creating the packages in BIDS worked fine for the development environment where I hard-coded the Connections and file paths. The problem arises when I will release this program to 30 different sites that do not have SQL Server admins to help changing the configuration.
I have a SQL table in which I will put all the necessary path information and I can pull that into the VB program on startup. I need to see an example of how I can set the properties from VB once the package is instantiated and opened.Here is an example of where I plan to set those properties and run the packages.
Private Function RunPackages() As Boolean
Try
Dim oApp As New Application
Dim oPackage As New Package
[code]....
Even though I am using a configuration file in the example, I am finding it difficult to edit the configuration files for each site. I see that there are methods and properties exposed for the oPackage instance. However, I can't find a good reference for the Class model to use as a guideline. All the examples expect packages to be run and configured with SQL Server and BIDS. direct manipulation of package properties in VB or C#?I am now considering using the old standby SQL Bulk Insert. It almost appears as if the Data Tasks are just wrappers for the Bulk Insert operation. Furthermore we have several sites still using SQL Server 2000. With the economy the way it is, most of those sites do not want to spend ANY extra money upgrading to SQL 2005 or 2008.
However, having a good resource to learn how to manipulate SSIS packages from the CLR would be very helpful. I have heard that in SQL 2008 things have changed even more. It is maddeneing that once I learn a "new" Microsoft technology it seems to be discarded by MS in their next release in favor of a "better" alternative.

I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then
DetailsView1.DefaultMode = DetailsViewMode.Insert
Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox)
txt1.Text = "administrator"
End If
But this returns an error of "Object reference not set to an instance of an object." Any ideas on how to accomplish this - either using the method above or another method?The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"
