• Michael Pritchard Windbg / SOS Callstack

  I'm unable to get source code file and line number information for the call stack functions reported by !clrstack in .Net 2.0. I've seen examples of this working in the 1.1 framework. Does it work in 2.0 If so, what's the trick Thanks for any pointers. The following article should be helpful in using SOS within Windbg. http://msdn.microsoft.com/msdnmag/issues/03/06/Bugslayer/default.aspx Hope that helps, Stephen I don't have an answer to your question!

• levyuk1 Get source code file path at runtime

  I would like to get a source code file name and full path at runtime for a specific class. Say I have a type MyClass and I want to use reflection or PDB to get the source code for that class. So the method should look like: string GetSourceCodePath(Type t) when I pass typeof (MyClass) it returns C:\MyProject\MyClass.cs Thank you You can get the stack frame of the current method or any of its callers by creating an instance of the StackFrame class. However I don't think this is really what you want to do given your further comments. You can't decompile your code through the standard .NET classes. Therefore you can't do this easily at runtime. You could use something like ildasm or s ...Show All

• Robert Mileski Is there any way to tell if a Process has been Killed?

  If I've got a Process object, is there any way to tell whether it exited normally or was Killed ( I believe the answer to my question is "no", but just wanted to verify that.) Thanks...Rick Hey... I'm not so good with this but, if you build that process, you may do two things: Check to returned value. When a normal exit is detected, ask your process to write some log. I'm not pretty sure, but I think Windows does not log this killing thing. I haven't tried this.. but one thing you might do is to inherit from the Process Class and add a new Property called WasKilled. Override or create a new Kill method for this object and set the wakilled value ...Show All

• 3jg1333 Software Remote application launching help needed

  We are programming on an application. I have to create a remote launcher kind of thing. Any ideas how can I launch one application on differenct parts of the world I am not talking about spamming on someone's system. We will use dedicated machines worldwide to test the performance of the application. Any help would be greatly apriciated. As a rule of thumb, you will have to run some of your software (an agent) on a machine that you want some more of your software to run on. You could, for instance, build a WCF service that is run as a Windows service and use that to launch additional applications. If you don't have any code running on the box, you can't start anything on the box. The only exception from this would be COM, but that' ...Show All

  Assume that I have drawn two coordinate axes on the screen (X and Y).

  hi! i am confused on what namespace (System.data.SqlClient, System.Data.OraclClient or System.Data.Odbc) should i use with my program... the program retrieves from sql (local server) and the values retrieved will be inserted to oracle (other server). My main question is what should i use and just to clarify what difference is there when i use an odbc connection from an sql or oracle connection thanks!

• Kapil Aggarwal .NET encourages poor coding?

  The more I look at .NET error handling, and how to deal with it, the more frustrating it gets. Take this class for example.   It has a single boolean property.   You have to know on which side of the call an error will be raised… by the caller or the callee… well here’s a prime example.    Say you have to read data from somewhere like a text file and you cannot ensure the format of the data is proper.   Well, you cannot depend on a property to check that data for you if you strongly type the property. Read the orange comment to see what I mean, and please let me know how you deal with this situation since to me it appears to require horrible program design.     Public Class ...Show All
