Centre An Element At Runtime?
Jun 2, 2011
I have a panel, 80 pixels wide and 720 pixels high. However, this panel will stretch to whatever height the user's display is at as the form border style is none and the form is set to maximise.
Inside the panel I have another panel, 78 pixels wide and 400 pixels high. As the form loads, how do I centre the nested panel?
x = Panel1.Width / 2 - Panel5.Width / 2
y = Panel1.Height / 2 - Panel5.Height / 2
If Panel5.Height < Panel1.Height Then

At the moment when i run my form1.vb program it runs in the top left of my screen, when i save it as an application and then open it from a shortcut will it still do this or will it open in the centre of the screen? In the designer it is in the top left of the screen, is there a way to move it here? as my assumption (which is probably wrong) is that the position it is in the designer is the position it is as an application? Is that right? and if it is how to i change the position in the designer?

Basically I currently have the following code which enables me to print the form perfectly.
CODE:
However, with the coding above on the print preview the form screen shoot/dump isn't centred. So I was wondering what would be the way to go about doing it? This is using the printform in the power packs available btw.
Also I figured it might be using height/width/location/margins etc, but I'm not to sure how one goes about assingning values to them. Like the two above I commented don't work.

I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

I am writing a Media Centre Addin in Vb.net and it was all going good until i got to the point where i want to find the "Currently Playing song FilePath or URl"I have spend a number of hours racking my brain to figure out a way of seeing what the "Currently Opened Files" are on a machine at any point of time.
My idea is to get all the currently opened files, and then filter the Extensions from these and find the media item that is currently playing, and get the filepath.Does anyone know how i can do this? and what methods or classes or Librarys i should be looking at or importing In..

I have been doing well and also I am a noob I know it and you know it a lot has started making sense and I am evening figuring new things out without using Google but of course I have hit another snag in my program so here goes
I am waiting for an email to arrive (the page automatically refreshes) and then I want to click the link (I do not need to click to open the email or anything like that) I also have the code to click and navigate to the address reason being it was the only way I could figure out how to stop it opening in a new window on IE
So my only problem is I need a way to check every x seconds for the element and then if its there proceed with my code and if its not wait and then check again or however this is done in VB.If this is not the way its done please point me in the right direction the code I am using to find and then navigate to the link is
Dim emailpageelements As HtmlElementCollection = WebBrowser2.Document.GetElementsByTagName("a")
For Each emailver As HtmlElement In emailpageelements
If InStr(emailver.InnerHtml, "https://twitter.com/account/confirm_email/") Then
WebBrowser1.Navigate(emailver.InnerText)

I am calling the OTA API from HP Quality Centre and one of the calls requires sending a NULL. This is the actual line of code:
stepF.AddItem(NULL)
This works perfectly in VBA and VB6 but VB.NET doesn't accept Nulls. Anyone know how to fix such an issue?

I have a tough situation that I don't really know how to code. I have one main list of point that contains all the points on a picture that are black.(1point=1pixel) I need to group all the black pixels that are less than 15(more or less) pixels away from each other into one Separate list. In the end I want about 5 lists.
What I said above is what I think is best to detect the centre of a shooting target. This information is just for those who think they know a better way. Each card has 5 targets on it and I need to detect the centre of each target. Ignore the sticker on the top target, in all cases the top one will look like the rest.

I am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.

I want to be able to reference an element in an array of structures by the name of the element in a visual basic 2010 function. For example
Public Structure myStruct
Public element1 as string
Public element2 as integer
Public element3 as boolean
[code]...
Is it possible to reference a structures element by the element's name in a similar way to that shown above. The code shown above does not work, as the expression obj(i).[elementName] does not work as hoped.

We have to get the data from a Ship to a Data centre which is located in a city. And the Ship has broad band connection via Satellite . So for capturing data from the ship we suggested to create a WCF services which will be deployed in Ship. And the Application Running on the Data center will call the service and get the data and upload it to the data centre . The same type of Application will be deployed in the data center to upload the data to the ship.
