Hi!

I have a window application.

User makes some selection from different combo boxes, then when hitted the "ADD TO CART" button, the data selected will be copied to some labels next to it.

But now, i need to transfer/copy all that data from the labels to a file named: computer.dat

How do i do that? I'm really having problems with that.

I have this there:

void storeInFile(Part *d)
  	{
    FileStream file = new FileStream("computer.dat", FileMode.OpenOrCreate, FileAccess.Read);

    for (int i=0; i<d->dataCount; i++)
    {
    	file << d->pb[i].processor <<"\n\n";
    	file << d->pb[i].memory <<"\n"<< endl; 
    	file << d->pb[i].harddrive <<"\n"<< endl; 
    	file << d->pb[i].cdrom <<"\n"<< endl;
    	file << d->pb[i].floppydrive <<"\n"<< endl; 
    	file << d->pb[i].keyboard <<"\n"<< endl; 
    	file << d->pb[i].monitor <<"\n"<< endl; 
    	file << d->pb[i].mouse <<"\n"<< endl; 
    }
    file.Close();	// close computer.dat
  	}

but im not sure if that's correct.

Please help me..:)

Thanks,

Look at your code, the "storeInFile()" is not being called.

You want it to work when you hit the "add to cart" button right?

so in your 

private void button1_Click(object sender, System.EventArgs e)
        {
            label12.Text = textBox1.Text += textBox2.Text += ", thanks for selecting us as your preferred brand!";
            label4.Text = comboBox1.Text;
            label5.Text = comboBox2.Text;
            label6.Text = comboBox3.Text;
            label7.Text = comboBox4.Text;
            label8.Text = comboBox5.Text;
            label9.Text = comboBox6.Text;
            label10.Text = comboBox7.Text;
            label11.Text = comboBox8.Text;


            !!!!!!CALL "storeInFile()" HERE!!!!! ( this is not real code :P  )

but there is a cleaner way to do this. Copy the code for storeInFile() and put it into the "private void button1_Click(object sender, System.EventArgs e)" code above ( in the spot where i have !!!!!!CALL "storeInFile()" HERE!!!!!) and you dont have to worry about that owner form1 mess but its all diffrent ways of doing the same thing.

so....

private void button1_Click(object sender, System.EventArgs e)
        {
            label12.Text = textBox1.Text += textBox2.Text += ", thanks for selecting us as your preferred brand!";
            label4.Text = comboBox1.Text;
            label5.Text = comboBox2.Text;
            label6.Text = comboBox3.Text;
            label7.Text = comboBox4.Text;
            label8.Text = comboBox5.Text;
            label9.Text = comboBox6.Text;
            label10.Text = comboBox7.Text;
            label11.Text = comboBox8.Text;

            // create a file stream, for "computer.dat"
            FileStream fs = new FileStream("computer.dat", FileMode.CreateNew, FileAccess.ReadWrite);
            // create a stream writer
            StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.ASCII);

            //write to file (buffer), where textBox1 is your text box

            sw.Write(label4.Text.ToString() + Environment.NewLine);
            sw.Write(label5.Text.ToString() + Environment.NewLine);
            sw.Write(label6.Text.ToString() + Environment.NewLine);
            sw.Write(label7.Text.ToString() + Environment.NewLine);
            sw.Write(label8.Text.ToString() + Environment.NewLine);
            sw.Write(label9.Text.ToString() + Environment.NewLine);
            sw.Write(label10.Text.ToString() + Environment.NewLine);
            sw.Write(label11.Text.ToString() + Environment.NewLine);

            // flush buffer (so the text really goes into the file)
            sw.Flush();
            // close stream writer and file
            sw.Close();
            fs.Close();


        } // end button1_Click

Its done and works .dat file and all. :)

I need to get back into programing, but all i play with is the windows media SDK in C#

I don't understand what you aren't seeing.

FileStream fs = new FileStream("computer.dat", FileMode.CreateNew, FileAccess.ReadWrite);

^^ That makes the object that will write the file.

fs.Close() will write it.

Also, lose the Flush!

is there a way of calculating the total price?

586579451[/snapback]

hmm so many ways.... since your combox selections are strings as are your labels, you can try a search of the string. Like for each label:

label1.TEXT = "Intel? Pentium? 4 Processor (3GHz, 800 FSB) [add $50]"

do a search in the string (label.TEXT) for the "$". Then get the number with a search from the "$" to the "]"

example "$"50"]" would be like

aString[n] = "$" (start)

aString[n+1] = "5"

aString[n+2] = "0"

aString[n+3] = "]" (end)

just get the 50 and convert to an int and add them up. THere is a method to do that in the String class.

Im sure there is a better way maybe someone can comeup with it

If you still need help i can give it a try. Im liking this and im scared that i am :blink:

Close() calls Flush(), but it does not call Dispose(). Dispose() calls Clos().

Fortunetly, you don't need to. When you populate the comboboxes, just use your items that derive from part. Override ToString() to get their text, like so:

        private void PopulateBox()
        {
            //Populate the box.
            comboBox1.Items.Add(new ItemForTheComboBox("Item1", 1));
            comboBox1.Items.Add(new ItemForTheComboBox("Item2", 2));
        }
        class ItemForTheComboBox
        {
            private decimal price;
            public decimal Price
            {
                get
                {
                    return price;
                }
            }
            private string name;
            public override string ToString()
            {
                return name;
            }
            public ItemForTheComboBox(string Item, decimal Price)
            {
                name = Item;
                price = Price;
            }
        }
        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            MessageBox.Show((comboBox1.SelectedItem as ItemForTheComboBox).Price.ToString());
        }

Here's something more suited to your program:

        abstract public class Part
        {
            internal decimal price;
            internal string name;
            internal Form1 owner;
            public decimal Price
            {
                get
                {
                    return price;
                }
            }
            public Part(Form1 Owner, string Name, decimal Price)
            {
                owner = Owner;
                name = Name;
                price = Price;
            }
            public override string ToString()
            {
                return name + " [$" + Math.Round(price, 2).ToString() + "]";
            }
        }

        public class Memory : Part
        {
            public Memory(Form1 Owner, string Name, decimal Price) : base(Owner, Name, Price)
            {
            }
        }
        private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            MessageBox.Show((comboBox1.SelectedItem as Part).Price.ToString());
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            comboBox1.Items.Add(new Memory(this, "512mb DDR", 50));
            comboBox1.Items.Add(new Memory(this, "1024mb DDR", 100));
        }

this will find the price by searching the label.

ex.

label4.Text = "Intel? Pentium? 4 Processor (2.80GHz, 533 FSB) [add $30]"

use: abc(label4); (make a better name than "abc")

it will return an interger thats 30.

so

int price = 0;

price += abc(label4);

price += abc(label5);

price += abc(label6);

price += abc(label7);

price += abc(label8);

price += abc(label9);

price += abc(label10);

price += abc(label11);

textBox3.Text = price.ToString();

public int abc( Label aLabel )
 ? ? ? ?{
 ? ? ? ? ? ?int price = 0;
 ? ? ? ? ? ?int startIndex = 0;
 ? ? ? ? ? ?int endIndex = 0;
 ? ? ? ? ? ?string subString;
 ? ? ? ? ? 
 ? ? ? ? ? ?startIndex = aLabel.Text.LastIndexOf("$"); ? // give me the index at char "$"
 ? ? ? ? ? ?endIndex = aLabel.Text.LastIndexOf("]"); ? ? // give me the index at char "]"

 ? ? ? ? ? ?subString = label4.Text.Substring(startIndex + 1, (endIndex - 1) - startIndex);

 ? ? ? ? ? ?return Convert.ToInt16(subString);
 ? ? ? ?}

:)l check again if there are any problems in a while, TV TIME :)

Whoa!

That really made sense.

But uhmm..

i added the:

price += abc(label4);

price += abc(label5);

price += abc(label6);

price += abc(label7);

price += abc(label8);

price += abc(label9);

price += abc(label10);

price += abc(label11);

textBox3.Text = price.ToString();

in the code you pasted and i think icant' get it to work.

Anwyays, i tihnk you might be watching TV (well-deserved)

I'll be here... so if you or anyone else could give me some help, i would appreciate it.

THANKS A LOT for the PATIENCE!

opps, there was a problem in the abc()

the correct way

public int abc( Label aLabel )
        {
            int price = 0;
            int startIndex = 0;
            int endIndex = 0;
            string subString;
           
            startIndex = aLabel.Text.LastIndexOf("$");   // give me the index at char "$"
            endIndex = aLabel.Text.LastIndexOf("]");     // give me the index at char "]"

            subString = aLabel.Text.Substring(startIndex + 1, (endIndex - 1) - startIndex);

            return Convert.ToInt16(subString);
        }

there was a boo boo in " subString = aLabel.Text.Substring(startIndex + 1, (endIndex - 1) - startIndex);" in the last post.

use it in 

public void calculatePrice()
        {
            int totalPrice = 0;
            totalPrice += abc(label4);
            totalPrice += abc(label5);
            totalPrice += abc(label6);
            totalPrice += abc(label7);
            totalPrice += abc(label8);
            totalPrice += abc(label9);
            totalPrice += abc(label10);
            totalPrice += abc(label11);

            textBox3.Text = totalPrice.ToString();          

        }

to clean stuff up and lastly just call "calculatePrice()" in your button event like:

        private void button1_Click(object sender, System.EventArgs e)
        {
            label12.Text = textBox1.Text += textBox2.Text += ", thanks for selecting us as your preferred brand!";
            label4.Text = comboBox1.Text;
            label5.Text = comboBox2.Text;
            label6.Text = comboBox3.Text;
            label7.Text = comboBox4.Text;
            label8.Text = comboBox5.Text;
            label9.Text = comboBox6.Text;
            label10.Text = comboBox7.Text;
            label11.Text = comboBox8.Text;

            // create a file stream, for "computer.dat"
            FileStream fs = new FileStream("computer.dat", FileMode.CreateNew, FileAccess.ReadWrite);
            // create a stream writer
            StreamWriter sw = new StreamWriter(fs, System.Text.Encoding.ASCII);

            //write to file (buffer), where textBox1 is your text box

            sw.Write(label4.Text.ToString() + Environment.NewLine);
            sw.Write(label5.Text.ToString() + Environment.NewLine);
            sw.Write(label6.Text.ToString() + Environment.NewLine);
            sw.Write(label7.Text.ToString() + Environment.NewLine);
            sw.Write(label8.Text.ToString() + Environment.NewLine);
            sw.Write(label9.Text.ToString() + Environment.NewLine);
            sw.Write(label10.Text.ToString() + Environment.NewLine);
            sw.Write(label11.Text.ToString() + Environment.NewLine);

            // flush buffer (so the text really goes into the file)
            sw.Flush();
            // close stream writer and file
            sw.Close();
            fs.Close();

            calculatePrice();
             
        } // end button1_Click

and thats it

According to Reflector:

public override void Close()
{
      this.Dispose(true);
      GC.nativeSuppressFinalize(this);
}



protected virtual void Dispose(bool disposing)
{
      if (this._handleProtector != null)
      {
            if (!this._handleProtector.IsClosed)
            {
                  this.Flush();
            }
            this._handleProtector.Close();
      }
      this._canRead = false;
      this._canWrite = false;
      this._canSeek = false;
      this._buffer = null;
}

      Well to finalise the thread, I bought the addin card as recommended but had teething problems trying to connect it to my eGPU. After much research, I found that rated cabling is a thing and after connecting a rated thunderbolt 4 cable to the new USB addin card I started troubleshooting. A few BIOS tweaks and updates here and there and everything is now connected and working. New eGPU is being picked up by Thunderbolt Control Center Thank you to anyone that stopped and read the thread especially to the tech resources that stopped to post and help. It was of massive help being able to reach out to the community as always. I just hope I haven't wasted too much of the community time trying to diagnose the problem. Thanks for your help again. 😊 Kind regards

    • Sony and Bungie delay Marathon indefinitely after 'passionate feedback' from community

      By kennyout · Posted

      The problem was that people who have played Extraction Shooters said there were too many missing features. Like Proximity Chat ...because of "toxicity". Lack of any story development even actually outlined. "Too watered down" for regular Extraction Shooter Enjoyers. Stupid amount of Aim Assistance on MnK. Questionable outdoor map design (how can something so "colorful" be so effing dull). Not to mention people still ###### they seemed to use the Marathon name and added in the alien/npcs after the fact, stappled on some other game concept they were working on. Like Arkane Studios was forced to use Prey as a title for their own original IP, by Bethesda to sucker in people for name recognition and ownership over the Prey IP. Which backfired with lower sales, due to the people realizing not a sequel or reboot, and the people who didn't like the original Prey.
