  • Convert VB.NET code to C#

    - by Sorush Rabiee
    Hi people, I have three projects written with VB.NET (2005) and have to convert them to C# code. (I know that i don't need to convert codes of .net languages at all). I have no time to rewrite them, need a tool or script to convert. Note: they are console applications.

  • Java Equivalent to .NET's DateTime.Parse?

    - by Superdumbell
    I'm working on a java class that I will use with Pervasive Data Profiler that needs to check if a Date String will work with .NET's DateTime.Parse. Is there an equivalent class or 3rd party library that can give me this functionality that is very close to .NET's DateTime.Parse?

  • Default .NET exception handler

    - by ajs410
    So the other day my C# application crashed. Usually, with a .NET application, if you have an unhandled exception you get a nice error message with a stack trace. However, this time, I got a different dialog that just told me there was an error and offered to attach a Debugger, but there was no stack trace in the dialog and the machine it was running on had no debugger installed. What gives? Why don't I see the default .NET exception handler?

  • What causes memory fragmentation in .NET

    - by Matt
    I am using Red Gates ANTS memory profiler to debug a memory leak. It keeps warning me that: Memory Fragmentation may be causing .NET to reserver too much free memory. or Memory Fragmentation is affecting the size of the largest object that can be allocated Because I have OCD, this problem must be resolved. What are some standard coding practices that help avoid memory fragmentation. Can you defragment it through some .NET methods? Would it even help?

  • How to safely store encryption key in a .NET assembly

    - by Alex
    In order to prevent somebody from grabbing my data easily, I cache data from my service as encrypted files (copy protection, basically). However, in order to do this, I must store the encryption key within the .NET assembly so it is able to encrypt and decrypt these files. Being aware of tools like Red Gate's .NET Reflector which can pull my key right out, I get a feeling that this is not a very safe way of doing it... are there any best practices to doing this?

  • Passing Strings by Ref

    - by SGWellens
    Humbled yet again…DOH! No matter how much experience you acquire, no matter how smart you may be, no matter how hard you study, it is impossible to keep fully up to date on all the nuances of the technology we are exposed to. There will always be gaps in our knowledge: Little 'dead zones' of uncertainty. For me, this time, it was about passing string parameters to functions. I thought I knew this stuff cold. First, a little review... Value Types and Ref Integers and structs are value types (as opposed to reference types). When declared locally, their memory storage is on the stack; not on the heap. When passed to a function, the function gets a copy of the data and works on the copy. If a function needs to change a value type, you need to use the ref keyword.  Here's an example:     // ---- declaration -----------------     public struct MyStruct    {        public string StrTag;    }     // ---- functions -----------------------     void SetMyStruct(MyStruct myStruct)     // pass by value    {        myStruct.StrTag = "BBB";    }     void SetMyStruct(ref MyStruct myStruct)  // pass by ref    {        myStruct.StrTag = "CCC";    }     // ---- Usage -----------------------     protected void Button1_Click(object sender, EventArgs e)    {        MyStruct Data;        Data.StrTag = "AAA";         SetMyStruct(Data);        // Data.StrTag is still "AAA"         SetMyStruct(ref Data);        // Data.StrTag is now "CCC"    } No surprises here. All value types like ints, floats, datetimes, enums, structs, etc. work the same way. And now on to... Class Types and Ref     // ---- Declaration -----------------------------     public class MyClass    {        public string StrTag;    }     // ---- Functions ----------------------------     void SetMyClass(MyClass myClass)  // pass by 'value'    {        myClass.StrTag = "BBB";    }     void SetMyClass(ref MyClass myClass)   // pass by ref    {        myClass.StrTag = "CCC";    }     // ---- Usage ---------------------------------------     protected void Button2_Click(object sender, EventArgs e)    {        MyClass Data = new MyClass();        Data.StrTag = "AAA";         SetMyClass(Data);          // Data.StrTag is now "BBB"         SetMyClass(ref Data);        // Data.StrTag is now "CCC"    }  No surprises here either. Since Classes are reference types, you do not need the ref keyword to modify an object. What may seem a little strange is that with or without the ref keyword, the results are the same: The compiler knows what to do. So, why would you need to use the ref keyword when passing an object to a function? Because then you can change the reference itself…ie you can make it refer to a completely different object. Inside the function you can do: myClass = new MyClass() and the old object will be garbage collected and the new object will be returned to the caller. That ends the review. Now let's look at passing strings as parameters. The String Type and Ref Strings are reference types. So when you pass a String to a function, you do not need the ref keyword to change the string. Right? Wrong. Wrong, wrong, wrong. When I saw this, I was so surprised that I fell out of my chair. Getting up, I bumped my head on my desk (which really hurt). My bumping the desk caused a large speaker to fall off of a bookshelf and land squarely on my big toe. I was screaming in pain and hopping on one foot when I lost my balance and fell. I struck my head on the side of the desk (once again) and knocked myself out cold. When I woke up, I was in the hospital where due to a database error (thanks Oracle) the doctors had put casts on both my hands. I'm typing this ever so slowly with just my ton..tong ..tongu…tongue. But I digress. Okay, the only true part of that story is that I was a bit surprised. Here is what happens passing a String to a function.     // ---- Functions ----------------------------     void SetMyString(String myString)   // pass by 'value'    {        myString = "BBB";    }     void SetMyString(ref String myString)  // pass by ref    {        myString = "CCC";    }     // ---- Usage ---------------------------------     protected void Button3_Click(object sender, EventArgs e)    {        String MyString = "AAA";         SetMyString(MyString);        // MyString is still "AAA"  What!!!!         SetMyString(ref MyString);        // MyString is now "CCC"    } What the heck. We should not have to use the ref keyword when passing a String because Strings are reference types. Why didn't the string change? What is going on?   I spent hours unssuccessfully researching this anomaly until finally, I had a Eureka moment: This code: String MyString = "AAA"; Is semantically equivalent to this code (note this code doesn't actually compile): String MyString = new String(); MyString = "AAA"; Key Point: In the function, the copy of the reference is pointed to a new object and THAT object is modified. The original reference and what it points to is unchanged. You can simulate this behavior by modifying the class example code to look like this:      void SetMyClass(MyClass myClass)  // call by 'value'    {        //myClass.StrTag = "BBB";        myClass = new MyClass();        myClass.StrTag = "BBB";    } Now when you call the SetMyClass function without using ref, the parameter is unchanged...just like the string example.  I hope someone finds this useful.

  • .NET Automated Build Server Software

    What good .NET Continous Integration and Automated Build and Deployment Software is out there? We have been using CruiseControl.NET but it is really starting to get on our nerves with the amount of maintenance it needs. We're looking for something that virtually anybody can manage, and it would also really be good to not have to write a NAnt build script. We use Subversion for Source Controll

  • .NET Regex Instance Caching

    - by jvenema
    I've read this article, which describes how instance vs static methods get called with a .NET regex. However, what about if the instance itself is static? Does anyone know if .NET does any sort of caching that could potentially cause a memory leak?

  • .NET Framework versions

    - by PintSizedCat
    I've had a little search and I was wondering if there is back compatibility for the .NET framework. The real question is, if there's a program that uses .NET Framework 1.1, can I install 3.5 and be done, or do I have to install 1.1 and then if something uses 3.5 I have to install 3.5 as well?

  • CruiseControl.NET : Sending email using SVN username to ActiveDirectory mapping

    - by matthewpe
    Is it possible to configure CruiseControl.NET to send an email to the user(s) that did modifications to a broken build by mapping their SVN username to the corresponding Active-Directory alias (hence retrieving the correct, updated email address). Our SVN server is set-up to allow users of a certain Active-Directory group to read and commit changes: I don't want to have to maintain the CruiseControl.NET config every time a user gets added to our Programmers group in Active-Directory. Thanks a lot!

Any ideas? The last message from debug is that the public key succeeded.

  • Convert between python array and .NET Array

    - by dungema
    I have a python method that returns a Python byte array.array('c'). Now, I want to copy this array using System.Runtime.InteropServices.Marshal.Copy. This method however expects a .NET array. import array from System.Runtime.InteropServices import Marshal bytes = array.array('c') bytes.append('a') bytes.append('b') bytes.append('c') Marshal.Copy(bytes, dest, 0, 3) Is there a way to make this work without copying the data? If not, how do I convert the data in the Python array to the .NET array?

  • Stick with MFC or go to .Net

    - by Jon Drnek
    We have a largish MFC app that is our main product. This app is being actively developed and there are no plans to stop development. I am new to windows development, but I get the impression that MFC is dead and all the new growth and enhancements are in .net. Is this view accurate? What criteria should we consider when deciding if we should convert this application to .net. Here I'm asking why. I have asked the how question here
