Check your app: look at the version of the .NET framework it is targeting.
VS2010 supports up to V4.0, but MSDN does say:
"However, the .NET Framework 4 ends this layering approach, so apps built for 2.0. 3.0, or 3.5 will not work on version 4 or later."
http://msdn.microsoft.com/en-us/library/bb822049(v=vs.110).aspx[^]

So if your app is targeting V3.5 or below, then installing V4.0 of .NET will not allow it to run. Either change the target of you app and rebuild, or install .NET V3.5

Hi guys am new to visual studio and c# programming stuff, tho have a good background knowledge of C and C++..

how do I go about having my entire source code in c # pasted to the visual studio , to run it from there??.I have a complete source code

If you have the complete source, then you probably want to open the .SLN file - it's a Visual Studio solution which should load the whole source correctly into Visual Studio ready for you to inspect / compile / run as you need.

You can not convert C/C++ code to C# without effort even your original C/C++ code was under the .NET framework. You will have to actually rewrite a part of your code...
If it was a Win32 API application you have even more work to do...

I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

I don't really understand. You said you have a good background knowledge of C and C++.
Does it mean you have knowledge or do you really have good experience and knows all the in and outs?

However, there is no way(as far as I know) of converting the C or C++ to C#. further if you are new to C# and Visual studio I recommend, to Spend few days in understanding the technology and learn the C#.

*.cs files open in Visual Studio if you mean you already have C# code. Else you'll have quite some fun rewriting everything. Although similar in syntax C/C++ are quite different than C#. If your C/C++ code also uses libraries it's even worse.

If the code base is not too large, analyze the code and note all the things that can be better. Then start from scratch rewriting the code in C#. This is very boring work, but it does advance pretty quickly.

ofcourse now implement 12-round RC5 (with 64-bit blocks) is susceptible to a differential attack using 2^44 chosen plaintexts in c# to find the key. do you have a pseudo code or code implement to GUI in visual c#. Smile | :)

Again, that's your research project, not ours.

Considering the dubious nature of what you're asking, you're not going to get anyone here to write this for you or even give you a hint about it.

I'm still not sure exactly what you're doing, but I can almost guarantee you that a GUI will be completely irrelevant.

Yes but i'm want to try using differential attack or bruteforce attack to find the key, btw thanks for the answer

What they mean is partly:

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.

And partly:

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.
Try it yourself, you may find it is not as difficult as you think!

So if you have a specific problem with your implementation, then we will help - if you tell us what the problem is.
But if you want us to write it for you, then you have come to the wrong site!

Sorry for the questions are a little disturbing, I wonder a little about saving all have to add any type of file that the file can be read:

code from encryption but add file nothing without type file. thanks for help in me Smile | :)

private void button1_Click(object sender, EventArgs e)
{
if (textBox1.Text.Length < 5)
{
password = textBox1.Text + "addto";
}
if (save())
{
try
{
password = textBox1.Text;
System.IO.FileStream streamreader1 = new System.IO.FileStream(fileName, System.IO.FileMode.Open, System.IO.FileAccess.Read);
System.IO.FileStream streamwriter1 = new System.IO.FileStream(saveFileName, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write);
rounds = (int)numericUpDown1.Value;
Rc5 rc = new Rc5(password, rounds);
rc.Encrypt(streamreader1, streamwriter1);
}
catch
{
MessageBox.Show("file may be in use by another process", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}

This is probably a translation problem, but I don't understand what you are trying to ask.
Perhaps an example of what is happening and what you want to happen would help?

The Rc5 class is not one I've seen - is it your own class? And if not, where is it? I don't remember it from the .NET framework.

sorry for the bad language, i have a little problem encrypt direct to save but saving file nothing without the type of file,
this forum can be include the picture of my problems (programs) ?
code for encryption direct to saving the cipher file:
private void button1_Click(object sender, EventArgs e)
{
if (textBox1.Text.Length < 5)
{
password = textBox1.Text + "addto";
}
if (save())
{
try
{
password = textBox1.Text;
System.IO.FileStream streamreader1 = new System.IO.FileStream(fileName, System.IO.FileMode.Open, System.IO.FileAccess.Read);
System.IO.FileStream streamwriter1 = new System.IO.FileStream(saveFileName, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write);
rounds = (int)numericUpDown1.Value;
Rc5 rc = new Rc5(password, rounds);
rc.Encrypt(streamreader1, streamwriter1);
}
catch
{
MessageBox.Show("file may be in use by another process", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}

Oh, and by the way, please try to use code blocks (<pre> tags) to preserve your formatting - it makes things a lot easier to read.

if (textBox1.Text.Length < 5)
    {
       password = textBox1.Text + "addto";
    }
    if (save())
    {
    try
        {
        password = textBox1.Text;

is shown as:

if (textBox1.Text.Length < 5)
{
password = textBox1.Text + "addto";
}
if (save())
{
try
{
password = textBox1.Text;

As you see in your question.

But...with tags:

<pre lang="cs">if (textBox1.Text.Length < 5)
    {
       password = textBox1.Text + "addto";
    }
    if (save())
    {
    try
        {
        password = textBox1.Text;</pre>

It is shown as:

if (textBox1.Text.Length < 5)
    {
       password = textBox1.Text + "addto";
    }
    if (save())
    {
    try
        {
        password = textBox1.Text;

Which is a lot, lot easier to follow!
