C# - Empty ListViewGroup Is Not Shown In ListView?
Mar 5, 2012I could not find any remarks on MSDN ListView.Groups Property that empty ListViewGroup will be hidden. Is it by design, or I am missing something? My sample code below will show only "group 2" with item "item1".
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
'
Dim gr = New ListViewGroup("group 1")
[Code]....
Is there are any way to show ListViewGroup without adding dummy item
For now the only workaround idea I have is to use collapsible listview (Vista and up)

View 6 RepliesAdding An Empty Row To A Databound Listbox Using Linq2SQL And Winforms?
Sep 28, 2011what is the most robust method for adding a empty row (to select "nothing") to a ListBox?
Dim List = Enumerable.Repeat(New TABLE With {.Text = "", .ID = -1}, 1).AsQueryable().Union(From t In mainctx.TABLEs)
ddlMangelKategorie.DisplayMember = "Text"
ddlMangelKategorie.ValueMember = "ID"
ddlMangelKategorie.DataSource = List.ToList
But this has some drawbacks:wordy must explicit write the Type (TABLE in this case), so i cant wrap this in a function have not found an solution, which works with anonymous types I.e. if I add a From t In mainctx.TABLEs Select Text=col1, id=col2 to the query, this method does not work anymore.

View 3 RepliesStop Scrolling Scrollbar Automatically While Adding Images In Winforms
Dec 23, 2011I have a thumbnail control where I am adding Images using openfiledialog and after adding it automatically scrolls down.
So I would like to stop scrolling the scrollbar and just append the Images.
I have tried using this code:
Thumbcontrol1.VerticalScroll.Value=0
It worked fine but the scrollbar is at the bottom and it shows me the first row of Images.
And this is my second attempt by doing this way:
I have just set the autoscroll property to false and it hides the scrollbars and I'm stuck with this so how do I scroll the remaining Images?
And Is there any other method to hide scrollbars and just scroll the Images using mouse? Or any other simpler way to get rid of this?
Winforms - Dynamically Adding Event Handlers To Dynamic Panels?
Mar 31, 2012so i have a series of panels that are generated
example:
For i as integer 1 to dt.rows.count
dim subpan as new panel
*Code for creating panel"
Next
the problem is i need to be able to add event handlers to each of them including, click, mouseEnter and mouseLeave but i can't figure out how to index each panel so that they can be accessed and identified. i tried using a property but that didn't seem to work or i was doing it wrong.
WinForms : "Not Responding" When Adding Rows To Datagridview?
Feb 20, 2012I've got a method that makes a request to a service that queries an SQL database, and then adds the result of the query in a datagridview row. I call that method in a "for each" loop.
It looks like this:
For each item in BigListContainingHundredofItems
Dim rowdata As String = GetRowResult(item, SomeDatabaseConnectionString)
Datagridview1.Rows.Add(rowdata)
Next
Basically hundreds of inputs are sent to the "for each" loop, and the way I've written it now it becomes "Not Responding" until all the rows have been added to the form (I can see the scrollbar handle size shrinking, which means rows are getting added).But I'd like to know how to keep everything responsive, and I think multi-threading or background worker thread might be the solution. I just wanted to get some input/feedback from the community.
IDE :: Set Project Default For Winforms Projects S/ Default Modifier For Controls Added To Winforms Is Private
May 28, 2010Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
View 1 RepliesWord 2007 Adding Adding Values To Combo List Box
Jun 7, 2011I am trying to create a simple Word doc that when the user presses the button it takes the information in the boxes and tosses it into a template style paragraph. But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?
View 1 RepliesVS 2010 Adding Unique Tag After Adding Component
May 4, 2012I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?
View 2 RepliesASP.NET Vs Winforms App ?
May 11, 2009I have a proto-type winform app designed by a colleague. My original plan was to create it using asp.net, but I'm not sure if I should just 're-create' it using asp.net or continue forward using the winforms. Either way, I'd use vb.net as the code-behind.
It's going to be a data collection app; originally it was going to allow the collection screens to by dynamically built, based on options selected by the end-users. However, that has changed to a one-size fits all approach.
I've never written anything using asp.net, so what I'd really like is some advice about what should I be looking for/at in this new app, in order to decide which way to finish it... asp.net OR winforms... Would there be any design/programming advantages to using asp.net over the winforms (other than the fact that my colleague already have about a dozen forms designed, but with NO code-behind)? Might there be end-user advantages to using asp.net vs winforms?
WPF App Vs WinForms App
Aug 10, 2009I'm currently studying for one of Microsoft's MCPD 3.5 certifications (VB 2008) and one of the things it makes use of is WPF applications. Based on what I've seen of them so far, they are basically like Windows Forms Applications. So my question about them is why was WPF created? What was Microsoft looking to accomplish with WPF since outside of the "web feel" in a windows environment, it basically looks like a WinForms application. What is the difference between the two and when sould I use one over the other?

And hopefully the 1 of the 20 songs in the ListBox2 will be randomly selected. But this code does not work; "Random is a type and cannot be use as an expression".
VS 2008 Using WinForms And Asp.NET Together?
Mar 7, 2012I've come up against a rather tricky problem that I cant seem to find an answer to.I have a WinForms program that runs locally on a PC with a SQL Server Express database to store its data.There is also a remote database that i need to save data to the first time that the program is run (a registration type thing).
The remote database will only accept connections from known IP adresses so to get around this, I have set up an ASP.NET site on the server that the remote database resides on and the data will be saved from here.
In my program, I have a form that has a webbrowser component on it that points to the asp site (with me so far?).The user fills in the form and clicks a button on the form that will fire the form to submit, save the data on the remote DB and retrieve a serial number that is displayed on the screen.

Is there another way to set the CurrentPrincipal property for all threads in the application?
