I have code for a custom DateTimePicker in this thread.>> Do I need to add an attribute to the properties to instantly show changes in design view please
View 8 RepliesI have created a form and dropped a MicrosoftReportViewer onto the form. It appears in the control panel on the bottom of the design view but it will not show up in the form. This is the second form I have done like this. The first one is fine. I can see the report viewer in the form and reports work correctly. For the second form nothing. Something I did notice is that in the first form the ReportViewer1 has a name in properties. In the second form there is no line with the name of the control.
View 4 RepliesI have a form where I have created a custom property, DataEntryRole, and set its Browsable attribute to True, as shown:
<Browsable(True)> _
Public Property DataEntryRole() As UserRole.PossibleRoles
Get
Return mDataEntryRole
End Get
[Code]...
When I view the designer for my form, DataEntryRole doesn't appear in the property box. I assume that it should appear if I were to create another form that inherited from this base form, but that's not what I want. I want this property to show up in my current form.
In IE, in the View pulldown, there is an item called Source.This displays a text file of the source html for that website.I am trying to capture my Play instantly Netflix movie list so I can display movie names on my analog tv that are large enough to read from the TV.Then, with a wireless mouse in the living room, I can navigate to a movie from the tv monitor and play a particular movie.How can I save this source data as a text file on my pc?The Queue gets updated periodically and everytime I start my program, I need to capture that source.[code]but I am not getting the Source that I see when I use the IE Source menu while my Netflix Queue is display in IE.

I seem to have reached a limit on the size of the form. I cannot make the form longer and I need to add more fields. Is there a limit on how many fields can be included in a form?
View 1 Repliessetting the default value for an integer attribute of a custom control seems to have stopped working. The following code adds the Maximum attribute to the design-time properties table, but the default value pops up as 0, not 99:

<System.ComponentModel.Category("Behavior")> _
<System.ComponentModel.Description("highest value possible")> _

View 5 RepliesHow can I shift the GET-implementation of a Class property to a / using a custom attribute? (I've added instantation vars (classname, propertyname) to the attribute, however I'd rather have these automatically fetched ofcourse.)

Public Property SomeProperty() as String

i wrote a custom attribute and got the following Color property that I want the user to be able to indicate the color property in the attribute on a class:
Private _ColumnColor As System.Drawing.Color
Public Property ColumnColor() As System.Drawing.Color

Why is the first line not correct? What it wants is a System.Type and a System.String but refuses to work.
I have a class created for use with the PropertyGrid control in a VB.Net application. One of the properties of the class is:
Private _someProp As String
<Browsable(True), _
BindableAttribute(False), _

I think know how to do this in C# but I'm having syntax trouble in VB.NET because I need to take advantage of the 'handles' event stuff. I have different events that I somehow (probably delegate) need stored in a property of an attribute (I just add an attribute to a property linking to the corresponding event).
E.g.
<BindEvent(EventThing)>_
Public ReadOnly Property IsTrue() As Boolean
Get
Return True
End Get
End Property
They need to be events so that other programmers can use the VB.NET handles keyword on methods.
Public Delegate Sub TestEvent(ByVal sender As Object, ByVal e As Object)
Public Event E As TestEvent
Public Sub Test() Handles E
End Sub
These properties are already raising a general event, which I am catching, determining the related property and thus getting the related attribute (and delegate/event). I want to then raise the event that's related. If I just use a delegate tied to the particular event that won't raise other handlers will it? I also want to avoid having to write a sub for each property that just uses Raise Event on the event type if possible as this seems redundant.
E.g. avoid:
Public Event E As TestEvent
Public Sub CallE(ByVal sender As Object, ByVal e As Object)
RaiseEvent E(sender, e)
End Sub
[Code] .....
Consider this scenario:
Class MyClass
Property SubProp1
End Property
[code]....
Next, I put an instance of MyButton into a property grid, expand property MC and edit SubProp2.From the type editor for SubProp2, I want to get hold of the attribute applied to property MC.Looking at the context,PropertyDescriptor.ComponentType, we arrive at Type: MyClass.If i look at the attributes applied to MyClass, though, it will only return the attributes applied directly to MyClass, and not the extra attribute applied to the property MC.
I have done some searching, but am still having trouble trying to set the browsable attribute of property to false at runtime in order to hide in the properties grid control (based on certain conditions).
View 9 RepliesI'm converting a project from .net 1.1 to 3.5, and everywhere the following is used in the markup:
Design_Time_Lock: true
e.g.
<asp:linkbutton id="lbRun" style="Z-INDEX: 111; Design_Time_Lock: True" runat="server">Run</asp:linkbutton>
[Code]....
I've read up about the Design_Time_Lock attribute, and I can see when it will and won't be generated. However I don't really understand the point of it. And- more importantly- can all instances of it be safely removed throughout the code?

View 1 RepliesI was loading my project when my computer rebooted suddenly. After it came back up, I went to load my project again and got an error about "an error occured when loading in the design view..this has been disabled" - sorry I did not get the exact message but it was something like this. Then when my project opened up, I now cannot see my form in the design view anymore. It still run's fine, but there is no code displayed and the form itself does not display in IDE anymore. I can see the code for the form only on the form.designer.vb mode.I have continues backup installed, and restored several versions of the class files for the form, but yet still no luck.

My project runs fine. I can compile and do all that good stuff. But I can not see for in design view.
I am making a program using Windows Form Application, and I had it set up in the design view. I double clicked a button to begin coding and up popped a ton of stuff in the code view that I had never seen before. I closed that, and somehow closed the design view by accident too. Now I can't get my design view back, even by re-opening the program (I didn't save), and double clicking the form to open it. It opens up as "Form1.vb" rather than "Form1.vb [Design]".What happened, how can I fix this and get my design view back?
View 2 RepliesI 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.
I was just wondering if it is possible to apply an attribute to a property within a business object (MyBusinessObject) such that after the DataSource of a grid is set to a List(Of MyBusinessObject), the visible property of the column will automatically be false. For example:
myGrid.DataSource = New List(Of MyBusinessObject)
Public Class MyBusinessObject

I have a simple class that I trying to populate from an XML document. The XML file has an attribute called TrackingID in the root node which I would like to get as a property. For some reason, when I deseralize the class, the TrackingID is null. Everything else populates fine. I have tried various attributes on the TrackingID property with no luck.

i'm on day one with VB05 express Beta 2 after a several-year break from VB6 after having a sudden surge of programming inspiration. i must say i'm quite impressed with a lot of the features, however, i'm really stumped by something that must be so simple that i'm just looking too hard or something.i've been looking for hours at how to return to the graphic design view of a form. i can't find it anywhere. all of the code from when i closed my project is still there but the visual representation of the form itself is nowhere to be found.

View 5 RepliesSo there I was working on a project. I was putting the finishing touches on the GUI and clicked on the Image list I had added. VB froze up a moment, and when it came back I was on a code view of the form showing the properties I had just set up in the GUI. Suddenly, I can in no way view the form. I get a View code option, but no View designer. If I close out the project and open another, there it is "View Designer" right where I expect it. But in the project I was working on, it is just plain gone.
Is there something I am missing here? Can I recover my project?
If I run it in the debuger the whole form shows perfectly, I just can't get to it to edit it.
Just a quick questio with what I'm sure will recieve an incredibly simple answer.Problem: After saving and restarting Vb the project I am working on seems to lose design view. In the 'view' drop down menu where you would see 'code menu f7' 'design view shift + f7' I only see the code view and not the design view. The tab for my project which would normally say form1.vb (design) now only says form1.vb. The coresponding window for that tab does not show the GUI I had created just a blank white page.
