And hey, how (and where) do I check if the size of the varchar/nvarchar fields of the DB have been specified, and if they've been specified correctly?

Thanks again, Smile | :)

Hi,
LAN connections and WAN connections are the same but with different IPs. Your LAN IP can be found from your local area connection's properties (if you have a PC) it's usually starts with 192.168 ,you know.
You can find your WAN IP from here[^].
Of course if you have a router or a firewall, you have to configure some settings called PortForwarding. It depends on your router model... PortForward.com[^] can help you in this issue.
Hope can helps

You have to know another PC's IP. If your application works on LAN, just change the LAN IP to another PC's IP...
Don't forget the router settings on another PC (if there's any).

That's a very vague question to ask...

If this app works over a network then you don't need necessarily need to change the program to get it to work over the internet.

Go google how the internet works, its a network just like any other, kind of. You need to get the public IP addresses of the computer to give to your application. If the computer(s) in question does(do) not connect to the internet directly, you'll have to set up NAT(network address translation IIRC)

Form form2 = new Form();
form2.Show();

Ofcourse you need to set its properties first, but it's easy.

Did you try the following way?

private System.Windows.Forms.Button btnEncodePath;
this.btnEncodePath = new System.Windows.Forms.Button();

//
// btnEncodePath
//
this.btnEncodePath.Location = new System.Drawing.Point(352, 19);
this.btnEncodePath.Name = "btnEncodePath";
this.btnEncodePath.Size = new System.Drawing.Size(75, 23);
this.btnEncodePath.TabIndex = 1;
this.btnEncodePath.Text = "Browse...";
this.btnEncodePath.UseVisualStyleBackColor = true;
this.btnEncodePath.Click += new System.EventHandler(this.btnEncodePath_Click);

this.Controls.Add(this.btnEncodePath);

It is very easy, please go to the InitializeComponent() method for more infomations. Smile | :)

Okay, when you click on the button the code below will open a new form. First, create an event handler for the button you want to click on, and then type the following inside the event handler:

Form MyNewForm = new MyNewForm();
MyNewForm.Show();

That's all there is to it. If you would like to know how to go about setting the properties programatically for your new form write back.

Hope this helps,

Introduction

Encode PHP is a tool to encode any php file
Every body can use it

Inside The Service

Click to the Encode button:

private void btnEncode_Click(object sender, EventArgs e)<br />
{<br />
    try<br />
    {<br />
        string LogFileName = "Log.txt";<br />
        FileInfo fi = new FileInfo(LogFileName);<br />
        fi.Create().Close();<br />
        StreamWriter writeLog = new FileInfo(LogFileName).CreateText();<br />
        string encodePath = this.txtEncodePath.Text.Trim();<br />
        string decodePath = this.txtDecodePath.Text.Trim();<br />
        if (!(string.IsNullOrEmpty(encodePath) || string.IsNullOrEmpty(decodePath)))<br />
        {<br />
            new IEncodePHP(writeLog).GetFileInDirectory(encodePath, 1, decodePath);<br />
            MessageBox.Show("Congratulation you encode successfully!", "Congratulation");<br />
        }<br />
        else<br />
        {<br />
            MessageBox.Show("Can not encode the source path!", "Warning");<br />
        }<br />
        writeLog.Close();<br />
    }<br />
    catch (Exception ex)<br />
    {<br />
        MessageBox.Show("Can not encode the source path: " + ex.Message, "Warning");<br />
    }<br />
}

Encode Method:

private string EncodePHP(string strEncoded)<br />
{<br />
    string variable1 = IRandom.GetRandomString(4, false, false);<br />
    string variable2 = IRandom.GetRandomString(3, false, false);<br />
    string variable3 = IRandom.GetRandomString(2, false, false);<br />
    string startVariable = " $" + variable1 + " = '";<br />
    string endVariable = "';";<br />
    string strDecode = "$" + variable3 + " = '$" + variable2 + " = base64_decode($" + variable1 + "); eval($" + variable2 + ");';";<br />
    string strEval = "eval($" + variable3 + ");";<br />
    strEncoded = startVariable + strEncoded + endVariable + strDecode + strEval;<br />
    return strEncoded;<br />
}

P/Invoke Exceptions

Hello,

If I call a (pure) C++ function from C# (using P/Invoke), and that function throws an exception, how will it be received in C#? Would it be wrapped into an object of Exception or one of its descendants?

Thank you.

I doubt it would be in a form that you'd hope, unless it's a COM exception. But yes, I imagine you'd get an exception that includes any message
