I'm a Crypto++ man myself. Years ago (circa 1998), I was never able to get a clean port of GMP to Windows.

Perhaps - I'll have to look at it.
Luc Pattyn wrote: Much depends on what it is you want to achieve.
This is going to be an article on Crypo++ interoperability with other Crypto Libraries and standards. The first article in this series is (somewhat out of order) is ASN.1 Object Identifier Encoding and Decoding[^]. It became such a large topic, it was spun off. In reality, it was supposed to be part of a Cryptographic Certificate Parser (*.CER, *.P7B, etc).
The TreeView is used for displaying results of the parser - the icons are a UI element aiding in vidualization of the message structure.

Hi Jeff, that's something we can look into. I'll send you an e-mail...

That is the cryptic message Microsoft has designed to tell you you don't have
(the right version of) the .NET Framework. So decide which version you need,
look for the download site and install it.

Someone voted you a 3 for that perfectly reasonable, logical and understandable question. Someone is obviously a moron.

Have you made an attempt to solve the problem yourself?

Hi.
I have the follow:
1. System.Data.DataTable dt = new System.Data.DataTable();
2. dt = dal.Search(findfile.Text); // I receive the data correctly
3. dt.WriteXML(YourSearch);// I'm trying to create a xml file from the datatable
4. Response.TransmitFile(YourSearch);//download xml file
In the thirth row, when i run (compile ok) I receive
"Cannot serialize the DataTable. DataTable name is not set"
What that mean?
thanks.

It means what it says. Set the TableName property for your DataTable.

I have this functionality i want to port from WinForms but i run into a few problems and i can't continue. What it does is move a panel(canvas) around as i click and hold and drag the mouse). I saw the sample using TranlateTransform(XAML) but i can't get any code-behind example, this is dynamic and interactive. I managed to make some out only need the translation solved(and possibly a good approach on using this with Margin, wich seems the only tool i got to moving the canvas around?).
Code Block#region Pan tool
private bool mMovingPanel;
private Point mMousePos;
private void panel1_MouseDown(object sender, MouseEventArgs e)
{
mMovingPanel = e.Button == MouseButtons.Left;
// prev mouse pos
mMousePos = panel1.PointToScreen(e.Location);
}
private void panel1_MouseMove(object sender, MouseEventArgs e)
{
if (mMovingPanel)
{
// "this mouse pos"
Point pos = panel1.PointToScreen(e.Location);
// "this mouse pos" - "prev mouse pos" = offset
Size adj = new Size(pos.X - mMousePos.X, pos.Y - mMousePos.Y);
// Location + offset = Location (final - unassigned)
Point loc = panel1.Location + adj;
if (panel1.Width >= this.ClientSize.Width && panel1.Height >= this.ClientSize.Height)
{
if (loc.X > 0) loc.X = 0;
if (loc.X + panel1.Width < this.ClientSize.Width) loc.X = this.ClientSize.Width - panel1.Width;
if (loc.Y > 0) loc.Y = 0;
if (loc.Y + panel1.Height < this.ClientSize.Height) loc.Y = this.ClientSize.Height - panel1.Height;
}
else if (panel1.Height >= this.ClientSize.Height)
{
if (loc.X < 0) loc.X = 0;

}
// Location(final - assigned)
panel1.Location = loc;
// "this mouse pos" set aside as "prev mouse pos"
mMousePos = pos;
}
}
private void panel1_MouseUp(object sender, MouseEventArgs e)
{
mMovingPanel = false;

This is my attempt, i know it lacks but hopefully it will speed things up:
Code Block#region Pan tool

mMovingPanel = Mouse.LeftButton == MouseButtonState.Pressed;
// prev mouse pos

}
private void panel1_MouseMove(object sender, MouseEventArgs e)
{
if (mMovingPanel)
{
// "this mouse pos"
Point pos = canvas1.PointToScreen(Mouse.GetPosition(canvas1));
// "this mouse pos" - "prev mouse pos" = offset
Vector adj = new Vector(pos.X - mMousePos.X, pos.Y - mMousePos.Y);
// Location + offset = Location (final - unassigned)
Thickness currentThickness = new Thickness();
Thickness loc = new Thickness(currentThickness.Left + adj.X, currentThickness.Top + adj.Y,
currentThickness.Right, currentThickness.Bottom);
if (canvas1.ActualWidth >= this.ActualWidth && canvas1.ActualHeight >= this.ActualHeight)
{
if (loc.Left > 0) loc.Left = 0;

I like C# but its useless in my applications because I can not protect my source code as its always included in deliverables.
Is there any real solution coming for this in near future or should I just give up C# .NET.
I believe this should be major concern for many but I haven's see Microsoft taking any role for this.

No.. You don't need to give your sourcecode to your client.. After making the setup file, there won't be any sourcecode in your setup file..

I tried this by making simple windows forms application and publish it. I select The application is available offline as well.
It generated setup.exe and subdirectory Application files. Under that there is file application.exe.deploy
I renamed that to be application.exe and open it Lutz Roeder's reflector. It was able to re-generate my source code from that. I think my clients can do same.

No. The generated code won't be the same as the original code that you wrote..

Atleast all of my business logic is there in very clear form.
I don't really feel confident. Reverse-engineering or hacking is other thing as this is way too easy to steal the hard work.

You would need to look at using an obfuscator[^] to make it more difficult to reverse-engineer the source code for your application.
