Play FLV directly from memory.

Wed, 18 Nov 2009 00:50:50 -0700

Hi!
I should develop a flash video player that plays FLV securely, i.e. it should be loaded from remote URL into memory, decrypted and loaded into the player. The problem is that the standard flash player activex is not able to play FLV from memory directly. Is it possible to avoid creating temp files?

Own an antivirus system in C#

Tue, 17 Nov 2009 01:47:12 -0700

Now I'm going to write own antivirus system with heuristic analysis. Main part is quite simple: antivirus provides access to virtual files for running application (maybe virus), which works with these files as if they are real. After this antivirus notify what running application attempted to do. I have BoxedApp SDK ( http://boxedapp.com/ ) for emulation of a file system and registry. But antivirus may be more effective and flexible if there are additional tools for recognition of viruses. Maybe there are some ideas (except simple compare of known viruses’ code parts)?

Thank you!

Hi!
Is it possible to use ActiveX controls and dynamic libraries without installing an application, by simply running EXE file? It’s means there is no temporary files, all ActiveX controls and DLLs are used from memory buffer.
Thank you!

Creating menu for a ASP.Net application

Mon, 16 Nov 2009 09:26:29 -0700

Hi,

I am creating an ASP.Net application in VS2008. I would like to create a horizontal menu bar at the top. The values of this menu bar should be dynamic. By dynamic i mean that we should be able to add new values or remove the existing values from the menu bar.

e.g. Menu options are: Import, Export, Search and Reports. The reports have 2 sub menus: A and B

Now if i want to add another menu tab sometime later in future, i should be able to do that not through the UI.

Any suggestions as to how can we implement this? Any small code snippet is welcome.

Thanks in advance.

Re: Connection String

Sun, 15 Nov 2009 23:50:59 -0700

Hi mohanavv..

First add OLEDB data adapter to your web page and fill the database information in the property windows of OLEDB data adapter.

thereby you will get the connection string from the same property window of the adapter.

Copy it and paste it in your source code.

Re: Hello!!!! Enybody out there???

Fri, 13 Nov 2009 12:08:03 -0700

you can save each data in the textboxes to a text file and loads it again when the appilication loads. something like this... when you should include

using System.IO;

//user closes the application

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
File.WriteAllText("c:\\data1.txt",textBox1.Text);
File.WriteAllText("c:\\data2.txt",textBox2.Text);
...

}

// when the user opens the application

private void Form1_Load(object sender, EventArgs e)
{
textBox1.Text= File.ReadAllText("c:\\data1.Text");
....
}

//Hope this helps

copying elements of global lists

Tue, 10 Nov 2009 12:14:52 -0700

I'm a hardware engineer doing my first c# program.

I have 2 global lists defined in my form as:

List <CUserMem> MemoryBank = new List<CUserMem>(100);
List <CUserMem> CombinedMemories = new List<CUserMem>(100);

The first list is used by several functions. Sooner or later, I must do "garbage collection" in a different function and extract (copy) the useful elements of the first list into the second list. This works the first time, but when I do that, the references are then set to be the same. The next time I update an element in the first list, the paired entry in the second list is also updated. I don't want that.

I tried to prevent this by reading the element of the first list into a temporary (local) variable and then copying the temp into the second list, but apparently when the local variable is destroyed the elements still have the same reference.

What's the right way to fix this?

Wed, 04 Nov 2009 16:10:17 -0700

public void SaveToDb(HttpServerUtility Server, int JezikID)
    {
        OleDbConnection conn = new OleDbConnection(new Util(Server).ConnectionString);
        conn.Open();

        //save text

        OleDbCommand cmd = new OleDbCommand("Insert into Tekst (JezikID, Tekst, tekst_rijeci, tekst_znak) values (@JezikID, @Tekst, @tekst_rijeci, @tekst_znak)", conn);
        cmd.Parameters.Add(new OleDbParameter("@JezikID", JezikID));
        cmd.Parameters.Add(new OleDbParameter("@Tekst", m_Text));
        cmd.Parameters.Add(new OleDbParameter("@tekst_rijeci", BrojRijeci));
        cmd.Parameters.Add(new OleDbParameter("@tekst_znak", BrojZnakova));
        cmd.ExecuteNonQuery();
        cmd.Dispose();
        
        // Save letters of bigram

        foreach(Ngram ngram in m_bigramCharList)
        {
            cmd = new OleDbCommand("select ID from BigramChar where bigram = @bigram", conn);
              cmd.Parameters.Add(new OleDbParameter("@bigram", ngram.Znakovi));
            cmd.Parameters.Add(new OleDbParameter("@bigram_broj", ngram.Count));
            object NgramID = cmd.ExecuteScalar();
            cmd.Dispose();

            // if there is no ngram, insert, or if it is ngram, update...

            if (NgramID != null)
            {
                int iNgramID = (int)NgramID;                
            cmd = new OleDbCommand("UPDATE BigramChar SET bigram_broj =  bigram_broj + @bigram_broj, bigram_txt = bigram_txt + @bigram_txt WHERE ID = @ID", conn);
            cmd.Parameters.Add(new OleDbParameter("@ID", NgramID));
                cmd.Parameters.Add(new OleDbParameter("@JezikID", JezikID));
                cmd.Parameters.Add(new OleDbParameter("@bigram_broj", ngram.Count));
                cmd.Parameters.Add(new OleDbParameter("@bigram_txt", BrojZnakova));
                cmd.ExecuteNonQuery();
                cmd.Dispose();
                
            }
            else
            {
                cmd = new OleDbCommand("insert into BigramChar (JezikID, bigram, bigram_broj, bigram_txt) values (@JezikID, @bigram, @bigram_broj, @bigram_txt)", conn);
                cmd.Parameters.Add(new OleDbParameter("@JezikID", JezikID));
                cmd.Parameters.Add(new OleDbParameter("@bigram", ngram.Znakovi));
                cmd.Parameters.Add(new OleDbParameter("@bigram_broj", ngram.Count));
                cmd.Parameters.Add(new OleDbParameter("@bigram_txt", BrojZnakova));
                cmd.ExecuteNonQuery();
                cmd.Dispose();
            }
        }

so table wont update fields, i tried this

here is my table with bigrams

ID JezikID bigram bigram_broj bigram_txt
922 5 ja 1 6
923 5 a 1 6
924 5 t 1 6
925 5 ti 1 6
926 5 i 1 6
927 5 o 1 6
928 5 on 1 6

foreach(Ngram ngram in m_bigramCharList)
        {
            cmd = new OleDbCommand("select ID from BigramChar where bigram = @bigram", conn);
			cmd.Parameters.Add(new OleDbParameter("@bigram", ngram.Znakovi));
			object NgramID = cmd.ExecuteScalar();
			cmd.Dispose();
			...

if (NgramID != null)
            {
                int iNgramID = (int)NgramID;
                    
                cmd = new OleDbCommand("insert into tbl_ID (charID) VALUES (@ID)", conn);
				cmd.Parameters.Add(new OleDbParameter("@ID", iNgramID));
				...

i have this in new table with ID of each bigram

ID charID
590 922 - ID of ja
591 923 - ID of a
592 924 - ...
593 925
594 926
595 927
596 928

so he found ID and he still does not want to update, if i try to do it like this and after i change the code and use exact numbers for @bigram_txt and @bigram_broj

foreach(Ngram ngram in m_bigramCharList)
        {
            cmd = new OleDbCommand("select ID from BigramChar where bigram = @bigram", conn);
			cmd.Parameters.Add(new OleDbParameter("@bigram", ngram.Znakovi));
			object NgramID = cmd.ExecuteScalar();
			cmd.Dispose();
			...

if (NgramID != null)
            {
                int iNgramID = (int)NgramID;
                    
                cmd = new OleDbCommand("UPDATE BigramChar SET bigram_broj =  bigram_broj + 1, bigram_txt = bigram_txt + 2 WHERE ID = @ID", conn);
				cmd.Parameters.Add(new OleDbParameter("@ID", iNgramID));
				...

he update fields with 1 or 2 it depends how much bigrams he found.
bigram is for example from word = "preview"
1. pr
2. re
3. ev
4. vi
5. ie
6. ew

Re: HELP ME! CODING ERROR!

Just simply remove the first boxes you entered, the IF statement alone is sufficient for exit box, see below
//CODE

private void button1_Click(object sender, EventArgs e)
{

if (MessageBox.Show"Are you Sure to Exit. Click Yes to Confirm and No to continue", "WinForm", MessageBoxButtons.YesNo, MessageBoxIcon.Question)== DialogResult.Yes)

{
Application.Exit();

else

MessageBox.Show("Thanx for not terminating me!", "As you wish",MessageBoxButtons.OK, MessageBoxIcon.Information);

Interactive Hello World question

Sun, 01 Nov 2009 11:23:03 -0700

I am working through the C# e-book. Here is the code for the part I have a question about:

using System.Text;

namespace InteractiveHelloWorld
{
class MainClass
{
static void Main(string[] args)
{
Console.Write("Please enter your name: ");
string name = Console.ReadLine();
Console.WriteLine
("Hello {0}, Good Luck in C#", name);
}
}
}

When I click Start Debugging in Visual Studio 2008, it pops up a command prompt window asking me my name, like it should. But when I type in my name and hit enter, it then displays the next line (Hello Marc, Good Luck in C#) and then immediately closes.

Is it supposed to close so fast like this? It only displays the second line for like a 10th of a second before closing. I can hardly even read the second line before it closes. Am I doing something wrong or is this normal?

Thanks
