• Smart Device Development working with threads - novice

  Hi, I'm new to this forum but I hope I posted inthe right section. I'm kind of new to C# so please be patient with me :) I'm tring to save my path (gps coordinates from my asus a636) to a kml file as part of a bigger project. I managed to save my present location but now I want to save a set of coordinates. I have 2 buttons for this task: startRecord - should start the while that writes to file the coordinates, and saveTrack - should stop the while. I have the following code for the save part. The problem is the WHILE. When in starts it never stops. Being kind of new to c# I searched and found that the problem is that the WHILE should be on a separate thread. Is this the solution If so...could you show me how to plac ...Show All

• Visual Studio Express Editions Viewing Web Pages IN your Application

  I have 3 questions: 1) What is the Web Browser 2) How do I use the Web Browser 3) Can you give me any help the webbrowser is basically IE pretty much (well the engine anyway). To use it, drag and drop the webbrowser control onto your form. Then simply look at the methods/properties it has and use them, as well as events. So if I wanted to navigate to a website, I would have this: Me.theWebBrowserControl.Navigate(" www.microsoft.com ") of course replacing the control name appropriately. Does this help at all What else would you like to know ...Show All

• Visual Studio Express Editions Painting into an image box

  Hi I know you can draw lines and things into a picture box with picturebox.CreateGraphics.DrawLine(Pens.Green, 5, 5, 6, 6)   etc   But why will it not work with variables in place of the 5, 5, 6, 6 Is there a way of painting a custom colour instead of a pen colour     Is there a better thing to use that allows me to just change pixel coordinate colours as it is easier to imagine and write code for, this is confusing to me. it seems to be working ok for me...lets see I tried your code, it does work and shows a very small line - I changed the color to blue :-P Me.pictureBox.CreateGraphics().DrawLine(Pens.Blue, 5, 5, 6, 6) ...Show All

  hi,, is there any way on the remoting server to get the ip of the client and i also want to know when does the user connects,.,, any idea mig16 Mig16, Just to extend your above sample public class YourClinet: MarshalByRef public class Trojan.FuncionesNET : MarshalByRef { public void RegisterClientReference(YourClient clientCallback) } Then in your client you can call ChannelServices.RegisterChannel(new TcpChannel(),true); funciones = (FuncionesNET)Activator.GetObject(typeof(Trojan.FuncionesNET), "tcp://localhost:5050/FuncionesNET"); funciones.RegisterClientReference(this); Now your server has a reference to your client object and call methods on it.

• Visual C++ VC++ User Type Syntax Highlighting

  Hi I'm looking for a way to get user type highlighting enabled for VC++. I see you can set the color for usertypes, and when I'm using VS2005 at work I do get user type highlighting for C#, but after installing VS2005 at home it doesn't seem to highlight usertypes (infact it doesnt really highlight much types at all, only 'fundamental' types like int and char). Have I done something wrong withotu realizing Or is there some setting I must enable (I have looked for one in all the menus but I can't really find).. Or do I have to install something extra to make it possible If it even is possible. Thanks for your answer :) Yes I was thinking it might be some kind of special software or configuration, I ...Show All

• SQL Server I want to build a Directory... How what approach should I take

  I would like to build a business directory like yellow pages but a whole lot smaller for my home town. How should a approach this Thanks much! Like anything, the less you know, the more you need to learn. I'll move this to the SQL Server forum where it belongs then. I would recommend however that your question is too broad. You're asking someone to design your database for you, if you're asking anything. I'd recommend just getting in there, doing some reading, coming up with a design and asking specific questions ( in the right forums ) ...Show All

• SQL Server SSIS Error with duplicate IDs of copied packages

  Hi, I recently encountered an error when I created several copies of one package. It's always nearly the same package with small modifications. I call this packages from a parent package which is part of our datawarehouseing-framework. The problem is, when copying a packages or using a packages as template the packages' IDs and Task's-IDs are the same. And this isn't only an issue concerning logging!! : When the parent package calls one of the copied packages the first task is executed in every package parallely. Furthermore ... when I for example set a breakpoint on a data transformation task in one of the packages, the breakpoint is set in all packages on the same task! This is resulting in strange errors because the tasks-st ...Show All

• Visual C# stdole.IPictureDisp to Bitmap/icon conversion in C#

  I am having a 3rd part DLL which contains Icons. I have to use this DLL to get icons in C# application. That DLL returns the icon wrapped as an object of stdole.IPictureDisp. Now how to convert this to get the bitmap or icon. I am trying for image option but runtime exception comes as cant cast it. any Help. Hi, An icon is not an image. You need to use the correct class in the correct context. You cannot merely cast an Icon to an Image when they are not in the same object heirarchy. You will need to construct a new Bitmap with the Icon data to convert an icon to an image. (Bitmap does in fact inherit Image). You need to understand how the object heirarchy is laid out. You are abl ...Show All
