How to make Gsm Sequential calls without blocking my application - C# Discussion Boards

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

i want to check my modem status every 5 mints.can somebody help with a c# code for that.

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.

i want to check mdoem status..status means..i heva lots of AT commands and i want to execute the methos which has all these commands evry 5 mints...can u help me with c#

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.

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();

         aux_function();

     }

     private void InitComPort()
     {

         axMSComm1.CommPort = 4;

         // This port is already open, then close.
         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;

         axMSComm1.CDTimeout = 10000;

         // No handshaking is used
         axMSComm1.Handshaking = MSCommLib.HandshakeConstants.comNone;

         // Use this line instead for byte array input, best for most communications

         axMSComm1.InputMode = MSCommLib.InputModeConstants.comInputModeBinary;

         // Read the entire waiting data when com.Input is used
         axMSComm1.InputLen = 0;

         // Don't discard nulls, 0x00 is a useful byte

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 !

hi
I have some prom problem with spliting mp3 file.
how can i split this type of file that work properly after spliting ?

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

can somebody help meeeeeeeeeeee Hmmm | :|

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

Do you mean a counter? If yes, use "static“ for z var.

I want to create tablelayoutpanel at runtime ..and this functionality same like how this control is doing at design time..like control moving and rows and Columns resizing..How these control is working at design time same like i need to create at runtime.

please any body know about this please tell me..

Thanks....

Create an object to TableLayoutPanel class and add it to your form. Go through the documentation to know what all properties are available. Set them and you are done.

The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

Hi,
All controls are created at run time and the code for controls that are "designed" within VS resides in the InitializeComponent method of the Form.designer.cs file.

If you are not certain how to write code for a control then just create a test form using the control you want to learn about. Open up the designer.cs file and all will be revealed. The code you would write yourself will be very similar.

i have 2 classes, i want to call a string from one method within a class to another class.

class SMSManager
    {
public string abc;
public void testMethod(string MPN, string RPN, string text)
        {
            SMSModem SMSMdm = new SMSModem();

            MessageBox.Show("RPN" + RPN);
abc = RPN;  //this isnt wrking
           
// HERE I HAVE A STRING CALLED RPN WHICH I WANT TO CALL INTO ANOTHER CLASS. THE RPN VALUE SHOULD
//BE THE SAME AS WHEN THE CODE EXECUTES THE ABOVE MESSAGEBOX CODE.

            int x = myArray.Length / 5;
           
            for (int i = 0; i < x; i++)
            {
                string a = myArray[i, 0];
                if (a == MPN)
                {
                    MessageBox.Show("MODEM NUMBER :"+MPN);
                    SMSModem SMSM = new SMSModem();
                    SMSM.SendSms();
                }
               
            }
             
           
        }

class SMSModem
    {

        {
            try
            {
                SMSManager MGR = new SMSManager();
                string num = MGR.abc;  //This is not retreiving the value!

//I WANT THAT VALUE TO BE CALLED HERE AND ASSIGN IT TO "num"
                MessageBox.Show("RECEIRE" +num);
               
                serialPort1.WriteLine("AT+CMGF=1;+CSCA=\"+6598540020\";+CMGS=\"+65" + num + "\"\r\n");
                System.Threading.Thread.Sleep(40);
                serialPort1.Write("Test message from coded program");

                char[] arr = new char[1];

                arr[0] = (char)26; //ascii value of Ctrl-Z

                serialPort1.Write(arr, 0, 1);

                System.Threading.Thread.Sleep(3000);
                string data = serialPort1.ReadExisting();

                MessageBox.Show(data);

                if (data.IndexOf("OK") != -1)
                {
                    return true;
                }
                else
                {
                    return false;
                }
            }
            catch
            {
                return false;
            }
        }
       
    }

MSManager MGR = new SMSManager();
string num = MGR.abc;  //This is not retreiving the value!
//I WANT THAT VALUE TO BE CALLED HERE AND ASSIGN IT TO "num"
MessageBox.Show("RECEIRE" +num);

string num = MGR.abc; before you can do this you need to call MGR.testMethod which actually does abc = RPN;

Alternatively

You can set the abc in a constructor.

Regards,
Karmendra

i call the MGR.testMethod in the button event in another form as:

            SMSManager sm = new SMSManager();
            
            sm.testMethod("82083427", "1122887779", "testmessagetxt");
        }
    }

how can i retreive the value then??

Think you need to re-visit OOPS concepts.

In button click event you have created another object sm and you have set sm.abc by running testMethod.

and you have never run SMSMdm.testMethod to set SMSMdm.abc, it wil give error also because you have never initialized SMSMdm.abc.

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            SMSManager <big>sm</big> = new SMSManager();
        }
        public void sampleArray()
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {            
            sm.testMethod("82083427", "1122887779", "testmessagetxt");
        }
    }

class SMSManager
    {
        public string abc="";
        public void testMethod(string MPN, string RPN, string text)
        {
            SMSModem SMSMdm = new SMSModem();

            MessageBox.Show("RPN" + RPN);
            abc = RPN;  //this isnt wrking

            int x = myArray.Length / 5;
           
            for (int i = 0; i < x; i++)
            {
                string a = myArray[i, 0];
                if (a == MPN)
                {
                    MessageBox.Show("MODEM NUMBER :"+MPN);
                    SMSModem SMSM = new SMSModem();
                    SMSM.SendSms();
                }
            }
        }

class SMSModem
    {
public bool SendSms()
        {
            try
            {
                //this is not required now
                //SMSManager MGR = new SMSManager();
                //string num = MGR.abc;  //This is not retreiving the value!

                //I WANT THAT VALUE TO BE CALLED HERE AND ASSIGN IT TO "num"

                string num = <big>sm</big>.abc;
                MessageBox.Show("RECEIRE" +num);
         serialPort1.WriteLine("AT+CMGF=1;+CSCA=\"+6598540020\";+CMGS=\"+65" + num + "\"\r\n");
                System.Threading.Thread.Sleep(40);
                serialPort1.Write("Test message from coded program");

                char[] arr = new char[1];

                arr[0] = (char)26; //ascii value of Ctrl-Z

                serialPort1.Write(arr, 0, 1);

                System.Threading.Thread.Sleep(3000);
                string data = serialPort1.ReadExisting();

                MessageBox.Show(data);

                if (data.IndexOf("OK") != -1)
                {
                    return true;
                }
                else
                {
                    return false;
                }
            }
            catch
            {
                return false;
            }
        }
       
    }

Remember all these should be in same namespace.

What do you mean it did not work? It is just a simple assign-op. Maybe you can debug it.

According to the cdoe, the value should be null.

Hi,
I have created a login in my winform application, i encrypt the password and store in a xml file.

I am worried about if the user deletes the xml file, he can crack into the system.

can you please suggest me how to make sure user cannot delete the xml file.

I tried embedding the xml file but, if i do that authorized users will not be able to change password and update the xml.

Please help

Thanks for your time and knowledge,
Karmendra

Why? If the application can not validate the password by using your xml file, in other words, the validation fails. In this case, the app should not let the user login. Hence, it should not be the problem at all.
