• Visual J# Why is the J# Redistributable package needed?

  Hi! Why is the J# Redistributable Package needed to run a J# application Or can I just redistribute some assemblies For example, if I develop an application in Borland Delphi using WinForms, I can compile this application to an exe file. This exe file can be executed on any computer that has the .Net Runtime Framework installed. No Delphi .Net Redistributable Package exists. If I develop an application in Dephi using the VCL.NET api all I have to do is to redistribute the VCL.NET assembly. That's easy. No problem here. So the fact is that it is possible to develop a new language for .Net (Object Pascal) and don't require some special in ...Show All

• .NET Development Process.Start() of xcopy only works under the debugger?

  I am trying to run a child process to xcopy files into another directory.  xcopy is regular old Windows system xcopy.  I am creating a new System.Diagnostics.Process, filling out some start info, then kicking it off with Process.Start().  When I run this code under the .NET debugger it works fine. However, if I run my app outside the debugger, the xcopy child process fails to do anything.  I've attached a debugger after I started my app outside the .NET IDE and although the child process appears to run, I get nothing from its stdout and the files I intend to xcopy are never copied.  This child process ...Show All

  In this very simple excerpted code, the compiler fails to do its job.  If you want it recreated, I propose someone there try to recreate it.  I've already got it happening here.  It's as simple as it gets.  From the type of failure, it looks like it's going to happen a lot. r12 is assigned the address of mc.decodePriority only if gDecodeMaxPriority >= 3, yet it, r12, is still used as the store address when it is not >= 3.  r12 is pointing to nowhereland in the code below, when, for example, gDecodeMaxPriority is 0.               if (mc.inWaveMode ! ...Show All

• Visual C# ArrayList copying a class

  I am reading a .csv file and loading each record that I read into a class then populating the class into an array list. The issue I have is that the class contains strings and seems to be copied by reference in the array list. Therefore causing an issue when adding additional records the reference is just being written multiple times in the arraylist with the same pointer. A friend suggested I use a dataset instead of an arraylist. I have to do sorting and filtering in which I would need to write functions for. I am not sure how to clone the class into the arraylist so that each entry is unique by value and not by reference point. Any help o ...Show All
