• .NET Development passing a dataset through a webservice

  Hi, I'm a really a newby in .NET webservices technologies. I've just started in. I want to pass a typed dataset from my client app to the webserver application. To start, I created a webmethod and passed a dataset parameter to it. For instance: <WebMethod> Public Function PassDataSet(ByVal orderDataSet As OrderDataSet) As Integer _orderDataSet = orderDataSet Return 0 End Function _orderDataSet is an attribute of the webservice class. The problem I have is that my _orderDataSet is not stored as persistent, so It becomes empty when I try to call it from an other method. I don't have any idea about how to perform that. I heard about XML serialization, but I don't know how to apply it in this simple practical case. Excuse m ...Show All

  Is there a way to add a link into the hover dialog so when the user clicks on it it'll generate the route and display directions No built in way to do it.

• Visual C# How can I share my custom user settings (ApplicationSettingsBase) with several objects?

  In my program I have several classes: WebServer EmailClient TelnetClient ...and they all use configurable data which I have in a class called "GNotifyUserSettings" (which is a descendant of ApplicationSettingsBase). Do I need to create a GNotifyUserSettings object in every class I want to use custom settings in ...or should I pass in an object reference to the user settings object to every class Neither method seems very clean. What I'd really like is a "global object" that every class can access...

• Windows Forms ListBox Help

  Sorry I accidently posted this already in the wrong forum Visual C# IDE. ... I have a ListBox who's contents change frequently. When they do I want the focus and selected item to be at the top. Heres my problem. When the contents change I call List.SelectedIndex=0; This causes the first item to change color as if it is selected. If the user presses down, however, instead of moving to the second item, it now "focuses" the first one (draws the dotted focus rectangle around it). Pressing down a second time goes to the second item and pressing it again, goes to the third as expected. The problem is I want the first item to be selected *and* focused so that when the user presses down for the first time it moves him/her to th ...Show All

• Visual Basic RunAs in Visual Basic

  Hi, Is there any way to use a VB form to supply user credentials to the Runas command in command prompt I basically need something exactly the same as the GUI for RunAs but just for Internet Explorer (yes I know you can right click and go RunAs but that cant be done in this case). So the user would open this VB form, type their username and password in, hit OK and it would open Internet Explorer with their credentials (they log in under a generic account used by many people). I have researched this for a long time and not having much luck... you can use the ProcessStartInfo class to supply it a username and password - the password being the securestring.

  Hi Mike, how do you generated the x86 code in one of your following blog http://blogs.msdn.com/jmstall/archive/2005/09/08/il_vs_native_offset_0.aspx Thank you for your help, Visual Studio will show you the native code for jitted C# methods. (It won't however show you the IL). ICorDebug exposes the native addresses of jitted code, so any managed debugger could show that information.
