Hi every body
i want to write a program to control one of my windows drives, for example i want to know when and by who (windows user), it is clicked.
i think that, there should be a windows service to control it, but i do not know the way to install a service and the registry key(s) which i should work with.
thanks

Problem with Listbox and removing items... [modified]

Hi.

I'm making an application and have a lot of problems.

First of all, i had trouble figuring out - how to get all the items to lower case.

Ok, i fixed that... but the program doesnt work the way it should.

So, the program should work this way:

You start the app. Then u click the button to get all the files from directory and all subdirectories. This goes ok. Ok, but then, i want to remove all doubles in the list.

If theres a file "BeBack.JPG" the app. should check if there's also "BeBack.PDF" or if theres "BlackWhite.PDF" and "BlackWhite_1.PDF" it should remove both entries from the listbox.
My code doesnt do that Frown | :(

i dont know why Frown | :(

It also deosnt remove all .gif files Frown | :(

Where did i go wrong? Please help?

Here's the code:

 private void button1_Click(object sender, EventArgs e)
        {
// for getting the items ToLower case
            string[] fajli = Directory.GetFiles(Application.StartupPath,"*.*",SearchOption.AllDirectories);
            string[] VsiFajli = Array.ConvertAll<string,>(fajli, delegate(string s) { return s.ToLower(); });

            listBox1.Items.AddRange(VsiFajli);

            for (int i = 0; i < listBox1.Items.Count; i++)
            {
                // checks if the file is .pdf
                if (listBox1.Items[i].ToString() == listBox1.Items[i].ToString().Remove(listBox1.Items[i].ToString().Length - 4, 4) + ".pdf")
                {
                    if (File.Exists(listBox1.Items[i].ToString().Remove(listBox1.Items[i].ToString().Length - 4,4) + "_1.pdf"))
                    {
                        string temp = listBox1.Items[i].ToString();
                        
                        listBox1.Items.Remove(temp);
                        listBox1.Items.Remove(temp.Remove(temp.Length - 4,4) + "_1.pdf");


                        //listBox1.Items.RemoveAt(i);
                    }
                }
                else // if its not pdf ...
                {
                    if (File.Exists(listBox1.Items[i].ToString().Remove(listBox1.Items[i].ToString().Length - 4,4) + ".pdf"))
                    {
                        string temp = listBox1.Items[i].ToString();
                        listBox1.Items.Remove(temp);
                        listBox1.Items.Remove(temp.Remove(temp.Length - 4,4) + ".pdf");
                        listBox1.Items.Remove(temp.Remove(temp.Length - 4, 4) + "_1.pdf");


                        //listBox1.Items.RemoveAt(i);
                    }
                }
            }
            MessageBox.Show("Done!");
        }

        private void listBox1_DoubleClick(object sender, EventArgs e)
        {
            if(listBox1.SelectedItem!=null)
            System.Diagnostics.Process.Start(listBox1.SelectedItem.ToString());
        }

        private void button2_Click(object sender, EventArgs e)
        {
// for removing all .gif items
            if(listBox1.Items.Count != 0)
            for (int j = 0; j < listBox1.Items.Count; j++)
            {
                if(listBox1.Items[j].ToString() == (listBox1.Items[j].ToString().Remove(listBox1.Items[j].ToString().Length-4,4) + ".gif"))
                    listBox1.Items.RemoveAt(j);
            }
        }

        private void button3_Click(object sender, EventArgs e)
        {
// copying the selected item to clipboard.
            if (listBox1.SelectedItem != null)
                Clipboard.SetText(listBox1.SelectedItem.ToString()) ;
        }

Thanks in advance.

The code is almost unreadable, please use the <pre> tags and use proper temporary variables instead of calling listBox1.Items[j].ToString() and others a hundred times. Also, did you know there's a EndsWith method?

Perhaps you can make a tiny demo and debug the code. That will be faster to find out the problem.

You can use timer object to run method every 5 minutes. As for modem what do you mean by checking it? You can send at commands to the modem.

You can check current System DateTime and every 5 minutes run your application.

Another way to do this is with a Windows Service.

Best Regards.

So what's wrong with my first reply? Use timer classes available in .Net Framework to run code every five minutes and use SerialPort class for sending at commands and reading responses.

Possibly a Windows Service, but a Windows Scheduled Task would be simpler.

How to make Gsm Sequential calls without blocking my application

Hi all!

Continuing my serial port fight Smile | :)

...

This time, i'm trying to make sequential Gsm Calls to diferent Gsm numbers. I'm doing some tests, but something's wrong.

My first dial connection is working fine, but when i close it and try to make the next connection, my application turns blocked... and i can't make other dial... Someone could help me with this? The use of filesystemwatcher is only for test purposes.

The code i'm using is here:

public bool GsmConnected;
     public bool GsmConnected2;

     public Form1()
     {
         InitializeComponent();

         FileInfo finfo = new FileInfo("C:\\Users\\AJorge\\Desktop\\GsmStatus.txt");
         StreamWriter ff = finfo.CreateText();
         ff.Close();

         InitComPort();

         this.Show();

         if (axMSComm1.PortOpen)
             axMSComm1.PortOpen = false;

         // Trigger the OnComm event whenever data is received
         axMSComm1.RThreshold = 1;

         // Set the port baud, no parity bit, 8 data bits, 1 stop bit (all standard)
         axMSComm1.Settings = "115200,n,8,1";

         // Force the DTR line high, used sometimes to hang up modems
         axMSComm1.DTREnable = true;

         axMSComm1.RTSEnable = true;

Hi,

Reposting is bad, but problem is urgent. Sorry for that !

I have a Web Application which referes to COM components for various reasons.
These COM components are built in VB6 and works fine when executed from Windows application from my machine.
This means, COM components are properly registered on my machine. When I gave reference to these from my Web App, respective Interop. DLL are created.

The COM component is the described as - "Microsoft VBUpgrade Tool TypeLib Visual Basic runtime objects and procedures" in VS.NET 2008 reference properties.

Question : I am getting following error when I try to create an object of VBRUN.PropertyBagClass

Error Message : An exception of type System.Runtime.InteropServices.COMException was raised and caught.<br />
Message: Retrieving the COM class factory for component with CLSID {D5DE8D20-5176-4EF2-8581-7B534D2AC56E} failed due to the following error: 80040154.

Stack Trace pointed to the line where object was being created

I searched google and came to a conclusion that I need to give rights of COM component execution for ASPNET account. I tried DCOM Configuration but am not sure to whom give the access rights and of what ?

It would be great if you guys give some sort of pointer to this ? Also wanted to make sure that my conclusion is right ?

Thanks !

You need to write headers in both halves. It's best to use DirectX for this, not do it manually.

// getphnum();

RoundRobin();
}
private int z = 0;
public void RoundRobin()
{

if (Modems == null)
throw new ArgumentNullException("Modem");
if (Modems.Length < 0)
return;

//int Count = 0;
int i;
int x = Modems.Length/4;

MessageBox.Show(Convert.ToString(x));
for (i = 0; i < x; i++)
{
string a = Modems[i, 2];
MessageBox.Show(a);
arrayValue = a;
MPN.Add(arrayValue);
}

for (int a = 0; a < MPN.Count; a++)

MessageBox.Show("ARRAY VALUE for index "+a+" "+Convert.ToString(MPN[a]));
}

}

public void getphnum()

z++;

MessageBox.Show(Convert.ToString(z));
}
}
}
in this when the getphnum() is called one time i wnat to get firts index value(ie index 0 ph number)ie MPN arraylist.ANd when next time when getphnum () is called i want to get index 1 value from arraylist MPN.(ie the same arraylist from which i call my first array index value)..

Take a static class variable and initialize it with the index of array and when you call the method again just add 1 to that variable i.e use that variable like a counter hope this helps sorry for the bad english.
If thats not what you want then let me know

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
