I have a listbox in which my selected products are stored like this ...
'Product name'.padright(30) 'price' 'quantity'
listBox1.Items.Add(details.Name.PadRight(30) + details.Price.ToString() + " " + 1 );
but when I read price of a product it selects price and quantity
string currentPriceString = foundItem.Replace(details.Name.PadRight(30), "");
string quantityString = foundItem.Replace(details.Name.PadRight(33), "");
I only want price in currentPriceString and quantity in quantityString
here is complete code of this method
private void ProductButton_Click(object sender, EventArgs e)
{
Button ProductButton = sender as Button;
DataAccess dataAccess = new DataAccess();
int ProductID = Convert.ToInt32(ProductButton.Tag);
Details details = dataAccess.ReadProductDetails(ProductID);
decimal price = details.Price;
string foundItem = CheckProductInListBox(details.Name);
if (!String.IsNullOrEmpty(foundItem))
{
string currentPriceString = foundItem.Replace(details.Name.PadRight(30), "");
decimal currentPriceValue;
string quantityString = foundItem.Replace(details.Name.PadRight(33), "");
int quantiy;
MessageBox.Show(currentPriceString);
if (Decimal.TryParse(currentPriceString, out currentPriceValue))
{
quantiy = Convert.ToInt16(quantityString);
currentPriceValue += price;
quantiy++;
string newItem = details.Name.PadRight(30) + currentPriceValue.ToString() + quantiy.ToString();
int index = listBox1.Items.IndexOf(foundItem);
listBox1.Items[index] = newItem;
}
else
{
MessageBox.Show("Error");
}
}
else
{
listBox1.Items.Add(details.Name.PadRight(30) + details.Price.ToString() + " " + 1 );
}
}
private string CheckProductInListBox(string name)
{
foreach (string item in listBox1.Items)
{
if (item.Contains(name))
{
return item;
}
}
return String.Empty;
}
On replacing (foundItem.Replace(details.Name.PadRight(33), "");), you are just removing the name part from the string, so the price and quantity will be there for sure.
You should can try this code,
// suppose your found text is like this,
//foundItem = "AMIT".PadRight(30) + "200" + " " + "1";
You can get price and quantity separately like below:
string currentPriceQuantityString = foundItem.Replace(details.Name.PadRight(30), "");
//currentPriceQuantityString => "200 1"
string[] strArray = currentPriceQuantityString.Split();
string currentPriceString = strArray[0]; //currentPriceString => "200"
string quantityString = strArray[1]; //quantityString => "1"
Side note:
I guess your line:
listBox1.Items.Add(details.Name.PadRight(30) + details.Price.ToString() + " " + 1 );
..should be:
listBox1.Items.Add(details.Name.PadRight(30) + details.Price.ToString() + " " + "1" );

I am trying to print a bill of sale, it works fine for me. But I have a problem, I don't know how to make the product description appear aligned, under the cut I make to print the rest of the description on a new line.
The full description is: "Aloe Vera Coco 12 x 1500 ml"
I leave the image and the code that prints the detail.
Someone who knows iText well and tell me how to solve this detail.
Thank you all

I have an API that loops through addresses and cleanses them. I am testing it with about 40k addresses, and it takes several hours to loop through thousands of them. Sometimes it throws an error and closes out the application and I have to start it over. Is there a way that I can write in error handling into the catch, that if there is an error, it will just log it, but continue running the app?
I am using VS 2019, C#, Windows Forms.

Essentially you need a way to save your work in progress. One pattern would be to load the file and store it in a database, then as you process each line you mark off which item you have processed. If you did this I would split the code into different modules, importing file, processing file, and exporting results.
Another simpler approach might be to write the results out as you process them, and record the line number from the input file. Then if you have to restart, find the last line you output and use that to skip reprocessing the items in your input file
I would like to write to and read from the same text file. However, I faced the issue of "The process cannot access "XXX.txt" because it is being used by another process".
I created two classes, A & B and define two objects for each of the classes in the main form.
Class A will be writing data into the text file while Class B will reading data from the text file at the same time.
I had put Class B in a timer while Class A will start when I click a button.

Anyone have any solution for this error.
Please help.
Thanks.
Make sure to call Close() on the writer to close it before reading. I've seen instances where utilizing a using block with the writer may not close it in time for the reader to be able to read it.
I have a system which inserts some recopies into a table. The thing is when I click the update button repeatedly it insert duplicate records into my database. Please help me to fix it.
Note: When I try to use the data in the table, these duplicate data does crash the program.

I have a function that retrieves multiple lines of data and I want to display them in a label. My function is as shown below.
public static string GetItemByQuery(IAmazonSimpleDB simpleDBClient, string domainName)
{
SelectResponse response = simpleDBClient.Select(new SelectRequest()
{
SelectExpression = "Select * from " + domainName
});
String res = domainName + " has: ";
foreach (Item item in response.Items)
{
res = item.Name + ": ";
foreach (Amazon.SimpleDB.Model.Attribute attribute in item.Attributes)
{
res += "{" + attribute.Name + ", " + attribute.Value + "}, ";
}
res = res.Remove(res.Length - 2);
}
return res;
}
So far I can only return a string which is the last line of the retrieved data. How can I retrieve all the records? I tries arraylist, but it seems that the AWS web application doesn't allow me to use arraylist. Can anyone please help me to solve this??
Return it as as a Enumberable,
List<String> Results ;
Your method would be
public static List<String> GetItemByQuery(IAmazonSimpleDB simpleDBClient, string domainName)
{
List<String> Results = null;
SelectResponse response = simpleDBClient.Select(new SelectRequest()
{
SelectExpression = "Select * from " + domainName
});
String res = domainName + " has: ";
foreach (Item item in response.Items)
{
Results = new List<String>();
res = item.Name + ": ";
foreach (Amazon.SimpleDB.Model.Attribute attribute in item.Attributes)
{
res += "{" + attribute.Name + ", " + attribute.Value + "}, ";
}
res = res.Remove(res.Length - 2);
Results.Add(res);
}
return Results;
}
