• Visual Basic argument not specified for parameter 'eventArgs' - calling sub in another UserControl

  If a UserControl contains a Sub such as Public Sub BackOne_Click( ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles BackOne.Click and another UserControl calls the Sub above as per; MainForm.ctlPostEdit.BackOne_Click() where it is defined on the MainForm as; Public ctlPostEdit As PostEdit.PostEdit, why/how would I solve the following error Argument not specified for parameter 'eventArgs' of 'Public Sub BackOne_Click(eventSender As Object, eventArgs As System.EventArgs)' This worked just as is in the previous vb6 app. Thank you, -Greg You have to provide the arguements specified in the method signiture (in this case, a S ...Show All

• Windows Live Developer Forums Polygon Circle outside map boundries

  I am currently implementing the ve api in such a way that we are plotting points on a map and drawing a circle (polygon) around that point on a map based on a provided radius. The point in question is in the Fiji Islands which would be on the rightmost part of the map (approx. Lat: -16.694078, Lon: 179.835205). The radius of the circle is large and there are points which lie outside the map boundaries. The circle gets plotted correctly which would be on both sides of the map. However, there are lines between the top and the bottom of each circle part and the outside of the circle is shaded in. I can't include an image in the post, so i have included a link here (yahoo for lack of a better place to put them): http://new.photos.yahoo.com/dad ...Show All

• Windows Forms WebBrowser - tracking button clicks

  I'm using the VS 2005 control System.Windows.Forms.WebBrowser. I want to be able to track button clicks. If I've navigated from a page with multiple buttons, how can I tell which button was clicked I have this in VB, but if you're using C# I assume you can do the conversion: Events: AddHandler webBrowserBody.Document.Click, AddressOf Me .webBrowserBody_DocumentClick AddHandler webBrowserBody.Document.Focusing, AddressOf Me .webBrowserBody_DocumentFocusing Both events use HtmlElementEventArgs, so I'll just show one of my handlers: Private Sub webBrowserBody_DocumentClick( ByVal sender As Object , ByVal e As HtmlElementEventArgs) Dim el As HtmlElement ...Show All

• Visual Studio Express Editions Write native Windows 98 Application in VB Express

  Is it possible to write an application in Visual Basic Express which runs 'natively' (i.e. without the need for .NET frameworks) on Windows 98 If so, how is this done If not, what's the best alternative for developing such an application on a Windows XP machine Thanks John Unfortunately no. Any application you write with a .NET language will require the use of the .NET Framework. The one quasi-exception to this is if you use C++ Express (or C++ from a higher version of Visual Studio) to make a native Windows application. If I may ask... why not target the framework and make sure it is installed on the 98 machine for your app to be used Just so long as you target 1.0, 1.1 or the 2.0 framework you' ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Possible bug? - Textures and Source Areas

  Hi, I've been experimenting and trying to draw a 2D texture (using a sprite batch) to the screen. Now I've specified a source rectangle for the texture - which is at (x, y) and of width & height 1x1. So essentially a single pixel from the source texture, which is RGBA (0, 0, 0, 255) i.e. solid black. When I render this and specify a destination rectangle, what's rendered seems to take into account the pixels either side of the source rectangle - which are RGBA (0, 0, 0, 0) i.e. transparent black. Now this seems to me slightly illogical or at the least counterintuitive - that pixels *outside* the source rectangle should affect what's being drawn! Well, if someone could explain this to me I'd appreciate it very much, or perhaps confir ...Show All

• Visual C# proper constructor chaining direction

  I was looking at some code at my work and with several overloaded constructors having the same code in each one, I thought, beautiful, perfect place to use constructor chaining. Except I'm not sure which direction is the proper way to go What I mean is, in the constructor, do you go from the general to the specific, using nulls for the missing parameters, or do you go from specific to general and then in the body of the constructor set the missing properties Where things get interesting is when you want to call the base constructor, should it go in one place If you're using constructor chaining, then you can do this, but where does it go, at the top or the bottom of the chain Here is a sample class that illustrates what I mean. ...Show All

• .NET Development Ultra-fast deserialization/serialization

  Hi, I'm wondering if there is a way to speed this up: I have objects that implement the following methods: public void Serialize(System.IO.BinaryWriter writer) { writer.Write(this.price); writer.Write(this.size); writer.Write(this.dateTime.Ticks); } public MyObject Deserialize(System.IO.BinaryReader reader) { return new MyObject(reader.ReadDouble(), reader.ReadInt32(), new DateTime(reader.ReadInt64())); } That's what I use for serialization & deserialization. Currently I manage to write 10,000,000 objects in 5.5 seconds, however my Raid 0 drives can write up to 140MB/s, so I think there should be some upside left (10mio objects result in 195MB file). I guess the problem is that the .Write ...Show All
