Showing Properties In Drop-down Of VB 2008 IDE
Feb 25, 2010
I'm using a masked text box control. It has a property, ValidatingType, that is not available at designtime so it doesn't appear in the properties window of the IDE. The IDE has two drop-downs where you can select an object in your project on the left drop-down and see the associated members on the right drop-down.
My question is: Why, if I select my masked text box control on the left drop-down, don't I see the ValidatingType property on the right drop-down? All the events for the text box appear, why not the property members as well? Perhaps because it only shows properties that I code for an object?

I have a vb.net baseclass in a dll in my c# project. I created a derived class in c#. I fill the C# class with all its properties, including the base properties from the vb class. Now I send them through a webservice (c# ) to a jQuery client. But on the client I only see the vb properties?
public class FilmItem : ContentItem // ContentItem is from VB DLL {
public string Zender { get; set; }
public string Jaar { get; set; }
[WebMethod]
public IEnumerable GetContentItems(VBLib.GridRequest gridRequest) {
ContentCache contentCache = new ContentCache();
return contentCache.GetFilms(gridRequest); // gives back a List<FilmItem>
}
Just found out that if I remove the vb.net class, all the properties are showing fine from the C# class. Also found out that the vb.net is declared like this:
Public Class ContentItem
Inherits System.Collections.Generic.Dictionary(Of String, Object)
Implements IContentItem
Could it be the dictionary or the interface? (Which sums up the properties I was seeing).

in my program I have a section that is outlined as listed below - in the page load, the label's visibility is set to false.
lblLoading.visable = true
lblloading.text = "loading please wait"
UpdateData()
lblloading.text = "Loading Complete"
It takes about a minute or 2 to run updatedata as it is doing multiple things to a database - when I execute this code, it stalls and loads the data, then when done I do get my label that says loading complete, but I never see the label before it is done loading to tell the user that it is processing. Is there any way to force it to show before UpdateData() is called so that it shows during the load time?

I have finally got the drag and drop to work on my form, so the user can drop files on it. I have used the msdn example so i can get the whole filename (path + filename). But how do i get only the filename? (lol.zip) And maybe the path where it is?

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 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've removed a few controls from my form, but they're still in the properties. I've looked in the Document Outline, but nothing. How can I remove them (save)?

I have lost the auto hide option (greyed out) on the drop down solution and properties menus. The Toolbox still has the auto hide option. I cannot find the pin to set auto hide on the Solutin and Properties menus.

I have combed these forums and the 'net and can't find an answer to my specific problem. My menu strip disappeared (after deleting a small secondary form within my project). I therefore created a new strip and while recreating the menu items realized that the original menu items are still present, showing in my properties list. I have checked my design file as well and the original menu strip is definitely gone but the original menu items are there. I don't have many items so I would have no problem just deleting the original ones but I can't see them to delete them! I have checked and they are all set to visible. I have also moved everything on my form to see if it is behind anything else.

I'm trying to figure out how to set the form's location/size before calling the .show method. I figured out the location part, but still can't figure out the size part. No matter what size I set the form to in the designer, it never uses that, so I figured I would set it with code right after setting the location.
'set location before .show
Form2.StartPosition = FormStartPosition.Manual
Form2.Location = New Point(103, 449)

I am trying to figure out a way to include the listview's tag field when dragging one listview's subitems into another listview. I am hoping someone here has experience with this. My Listview drag code is below - the two listviews that I am dragging subitems into or from are LV1 and LV3. Also, this is being done in Visual Basic 2008 and the project is a windows application.

I have my VB.NET exam tomorrow and I have a list of potential questions, and there is this one question I really fail to find a good explanation for. it gives me this function:
Dim x, y as Single
y=2
y=x+10
MsgBox(x)
it returns 0... and I am supposed to explain what that happened. I have tried changing the numbers so it gives a positive number, and then it works properly... I have tried changing the type too, and still 0.

I am trying to polish up a program a program that I have converted from a Windows Form in to an ASP.NET Web Application. I have several questions:
1.) I have a drop down box where users can select their variables, but users can also enter their variables manually into various text fields. What I want is for the drop down box to show a string like "Choose Variables" when ever the user enters their variables manually. I want this to happen without having to reload the page.
2.) In the Windows Form version of this application I had a RichTextBox that populated with data (line by line) after a calculation was made. I used "AppendText" in my Windows Form, but that is not available in ASP.NET, and neither is the RichTextBox. I tried to use just a text box but that isn't working right.

I have been given an assignment which is to program a working payroll system in Visual Basic 2008.I have done most of it but I am stuck at the arrays.I would like my system to store all the staff name that the user adds on the system into a single Array for example in EmployeeNames(50). For example if the user enters a new staff in the textbox name and confirms it by clicking on a button, I would like that staff name to be stored into my Array EmployeeNames(50).

I have an MDI application. Upon starting it, the MDI form is instantiated, then it kicks off a Username/Password log-in form and makes itself invisible(user never sees the MDI form). If the user logs in, the log-in form becomes invisible and the MDI form becomes visible. This works fine, except for one user.When the log-in form comes up, the MDI form is also visible. If he clicks on something, it crashes(certain variables aren't set at that point). If he logs in, however, the log-in goes invisble and everything works fine. This guy is a network admin/IS type and has several versions/hotfixes of the .Net Framework installed. Could that be the problem? Does anyone know what could be causing this problem for this one user and no one else?

I have an application which is using a set of three combo boxes. I have managed to populate each drop down depending on the selected value of the previous one The only problem is that, since the data is coming the database two selected values from the first combo box may have two different number of items in the database. so the second combobox should be populated with such data each time the selectedIndex_changed nethod of the first combobox is invoked
if for example, the first combo box's first item has 10 corresponding items in the second combo box and a first combo box's second item has three corresponding items in the second combo box, selecting the second item after selecting the first item will lead to second combobox showing the three items and seven empty entries trailing after the three.
What I want is to have the second combobox loaded with three items exactly when the second item in the first combo box has three items in the database
here is an example
Private Sub cboAccountGroup_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboAccountGroup.SelectedIndexChanged
If mblnAccountGroupFirstLoad = True Then
Exit Sub
