• .NET Development LinkList or List, which is faster?

  I thought LinkedList would be faster than List but I ran a test and it showed they were about the same speed. Anyone else done a test like this It doesn't make sense that List would be as fast and LinkedList. My test was reading in a 300 meg data file (row, column), and then writing to the data. You are absolutely correct, Matthew.  I should have included an example since I didn't want to include all of the code I was testing.  I made an example.  I agree with the insertion comment.  List Time 1.8125 Linked List Time 1.84375   using System; using System.Collections.Generic; using System.Text; namespace TimingTest {   class Program   {   &nb ...Show All

• .NET Development Setting Optimistic approach when no primary key exists

  Hi, I have two DataSets. My first one contains a single DataTable which has a primary key. I could easily configure the corresponding TableAdapter to handle "Optimistic Concurrency" and then verify that the coding for the "update" as well as the "delete" SQL statements were set accordingly. My second DataSet also has a single DataTable but this time with no primary key at all. The reason why there is no primary key starts from the fact that this table will only contain one record. My question would be the following: Starting from the fact that: 1- the designer seems to implement optimistic concurrency coding for Update/Delete SQL statements only when there is a presence of a primar ...Show All

• Visual C++ help with linked list

  I'm having some problems with linked list. I'm working on a small program that deletes a node somewhere in the middle of the list. I don't seem to understand what is wrong with this code below. I know the syntax it correct, but when I try to delete a node somewhere in the middle, it deletes that node just fine, but I believe that I'm not tying my pointers together right. Deleting is not the problem, the problem comes when I display the list again. I will display before I delete the particular node I want, but after the node is deleted, it crashes the program when I display the list. I've tried this one several different ways. (#1, using a temp node to "bookmark" my spot at the node(current) for deletion) temp=current; pr ...Show All

• .NET Development 2146233079 automation error while createobject on interop assembly (only second time)

  Dears, I have the following bizar problem. I've created a .NET assembly (dll) that can be created from COM (vb6 in my case). When I create the object the first time, everything goes fine. But the second time, I get an error on the CreateObject (-2146233079 automation error). I was unable to retrieve any more information from the error object in vb. I registered the .NET assembly using regasm (I tried both with and without the /tlb option). The .NET assembly simply queues the items it receives and spawns another thread that consumes the items. The spawned thread exits gracefully, and all calls to the DrillBackDotNetDispatcher return to vb. The second creation of the object is made after both the last call to addItem has returned and the t ...Show All

• Visual C# displaying an image via the default windows program

  Hello everybody, I mostly work in C\C++ projects and by using MFC. However I have a project that I wrote in C# (VS .Net 2003 - framework 1.1). My Question is: How can I launch (from whitin my application) the default windows program for images displaying (and passing into it the image) I would prefer to pass the image as an image stream (if it is possible). And by the way one more question: I read in MSDN that i should not close a Stream that an image currently uses. In most of the cases, in my code, I do not close the memory streams that I create to load an image from. Is this a memory leak or .NET Framework does the work for me when the Image is out of scope Thank you all for your tim ...Show All
