• Visual Basic Send Image from VB6.0 to .Net webservice

  How to send a Image from vb6.0 to .net webservice. Hi Thanks alot for quick reply There are certain issues Client machine will not have .NET framework . So it is not feasible to have .Net Component. Sending using Soap attachment. Soap toolkit has bugs in code for sending attachments.

• SQL Server Merge replication - examples for custom conflict resolvers?

  I have gone through BOL and various online resources including this one and I can't find any examples on how to use custom conflict resolvers to generate a result row which is a combination of the rows to be merged. BOL says it can be done, but suitable examples are missing. I have found various posts requesting examples from up to a year ago, but can see no replies with relevant information In particular I would like to see examples of 1) A stored procedure based custom conflict resolver 2) A business logic handler written in VB .Net Here's hoping aero1 You might want to look at the additive conflict resolver. This will do something like concatenate or add the two values together. You ca ...Show All

• .NET Development Window.open, but in a new process...how?

  How can I open a new window in seperate process I have found the following: function openNewProcess(url){ set IE= CreateObject( "InternetExplorer.Application" ); IE.Visible = true ; IE.Navigate(url); } This is not what I want as some of our clients don't use internet explorer.

• Windows Forms Can't get DrawItem event any more, in some special case

  This interesting thing was found by use of DebugView to monitor the all events. Suppose that there are 2 controls, one is propertyGrid, one is myListBox, which is a subclass of ListBox. myListBox uses OwnerDrawFixed mode, so it has to draw all items manually. However, in some mysterious case, I found that when I repeatedly opened and closed the propertyGrid, myListBox may never raise any DrawItem event. I output all events to DebugView, then found that WM_PAINT was there, but didn't WM_DRAWITEM. Also it can't restore from this bad status no matter what I did (move, refresh, resize, maximize, minimize...), until I recreate another myListBox. I think WM_DRAWITEM is nowhere to be manually emitted, since it's managed by control. ...Show All

• Visual C++ Managed code compilation

  I know Native C++ makes a more resource efficent program than C#.NET or VB.NET; I also am pretty sure it makes a more efficent code than Managed C++ (correct me if I'm wrong) What I would like to know is if functionally equivalant managed C++ code is more efficent than C# code Thanks in advance. another question: if you wanted to make a GUI in C#, but behind the scences you had some heavy number crunching to do, resource-wise, would it be worth it to make a external native C++ dll to do the crunching, that you refrenced from the C# GUI exe ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. A very simple terrain component.

  Hey, I was inspired by the game components demo Mitch put up the other day, to toss together a terrain component of my own. Just be sure to supply it with a texture. 'N' generates a new terrain on the fly. It uses the BasicEffect for rendering (cudos to Microsoft for ditching fixed function). The Perspective, World, and View matrices are all hard coded though, so you can't move around or anything.

• Windows Forms Creating icons and .ico files.

  Hi, I'm in the middle of learning C# and for a web browser I'm creating and I need to make my own Icons. I was wondering if anyone knew of a [Free] application that would convert BMP images into .ico files Also, if anyone can help, does anyone know of a free, standalone, vector graphics programme so I could use that instead to make icons and/or .ico files I know Open Office has a vector graphics application but you also have to have the rest of Open Office as well. you could make your own quick bmp to ico converter, whether this will work for most bitmap images I don't know as I think it depends on the size of the bitmap in order for it to work to be an Icon....
