private void btnAssemble_Click(object sender, EventArgs e)
{
txtAssembled.Text = (cboTitle.Text + txtFirstName.Text[0] + txtMiddle.Text + txtLastName.Text + "\r\n" +txtStreet.Text + "\r\n"+ cboCity.Text);
}
I'm trying to get 1 character white space inbetween cboTitle.Text, txtFirname.Text, txtMiddle.Text, and txtLastName, but they all output the information together, but I want them spaced evenly. what do I need to do? thanks in advance.
I'm going to post some other code thats below the one above in my project, just in case it might be relevant.
string AssembleText(string Title, string FirstName, string MiddleInitial, string LastName, string AddressLines, string City )
{
string Result = "";
Result += Title + " ";
Result += FirstName.Substring(0, 2) + " ";
// Only append middle initial if it is entered
if (MiddleInitial != "")
{
Result += MiddleInitial + " ";
}
Result += LastName + "\r\n";
// Only append items from the multiline address box
// if they are entered
if ( AddressLines != "")
{
Result += AddressLines + "\r\n";
}
//if (AddressLines.Length > 0 && AddressLines.ToString() != "")
//{
// Result += AddressLines + "\r\n";
//}
Result += City;
return Result;
}
}
}
If you just want a space between those specific fields in btnAssemble_Click, you can just insert them like this:
string myStr = foo + " " + bar + " " + baz;
So your first function would be modified to read:
private void btnAssemble_Click(object sender, EventArgs e)
{
txtAssembled.Text = (cboTitle.Text + " " + txtFirstName.Text[0] + " " + txtMiddle.Text + " " + txtLastName.Text + "\r\n" + txtStreet.Text + "\r\n" + cboCity.Text);
}
A few other comments:
It's not clear to me what the AssembleText() function you posted has to do with this. I am confused though, as I see a few lines appending spaces at the end just like I mentioned above.
Using the String.Format() function may make this code easier to read and maintain.
Using Environment.NewLine instead of "\r\n" will make the string contain the newline character defined for that specific environment.
Using a StringBuilder object may be faster over concatenation when building strings inside of a loop (which may not apply here).
Using String.format() should feet the bill. It also make your code easy to read.
txt.assembled.text = String.Format("{0} {1} {2} {3}",
cboTitle.Text,
txtFirstName.Text[0],
txtMiddle.Text,
txtLastName.Text
);
It would be like this
private void btnAssemble_Click(object sender, EventArgs e)
{
txtAssembled.Text = (cboTitle.Text + " " + txtFirstName.Text[0] + " " +txtMiddle.Text + " " + txtLastName.Text + "\r\n" +txtStreet.Text + "\r\n"+ cboCity.Text);
}
It seems that you want String.Join; whenever you want to combine strings with a delimiter, say, " " (space) all you need is to put
String combined = String.Join(" ",
cboTitle.Text,
txtFirstName.Text[0],
txtMiddle.Text,
txtLastName.Text);
Complete implementation (joining by space and new line) could be
txtAssembled.Text = String.Join(Environment.NewLine,
String.Join(" ",
cboTitle.Text,
txtFirstName.Text[0],
txtMiddle.Text,
txtLastName.Text),
txtStreet.Text,
cboCity.Text);

I'm currently having some issues with my CSV to SQL Converter. With this being my third week of learning C# I'm starting to grasp some stuff but this is going over my head a bit.
What I'm trying to do is have the Top row/Titles taken down split into each individual title and then for the SQL code through that rather than entering it manually like I've done. Below you can see some of my code that I've built so far.
private void Form1_Load(object sender, EventArgs e)
{
try
{
// your code here
string CSVFilePathName = #"C:\\CSV\\reg.csv";
string[] Lines = File.ReadAllLines(CSVFilePathName);
string[] Fields;
//1st row must be column names; force lower case to ensure matching later on.
// get regs from filename
// get fieldnames from Lines[0] (first line of file)
// create a loop for fields array
string hdr = Lines[0];
for (int i = 1; i < Lines.Length; i++)
{
Fields = Lines[i].Split(new char[] { ',' });
CSVTextBox.AppendText(Fields[0] + "," + Fields[1] + "," + Fields[2] + "," + Fields[3] + Environment.NewLine);
// need a for loop for each field
// for (
SQLTextBox.AppendText("INSERT INTO[dbo].[REGS]([SESTYPE],[REG],[LFL],[SUBVER]) VALUES('" + Fields[3] + "'" + Fields[0] + "'" + Fields[1] + "'" + Fields[2] + ")" + Environment.NewLine);
// }
}
}
catch (Exception ex)
{
MessageBox.Show("Error is " + ex.ToString());
throw;
}
}
This all runs at the moment, I'm just struggling to get the titles to become part of the code. Any help would be appreciated.
Cheers,
First: Remove the try catch. If you get an Exception, you should read, understand and clear off.
For your SQLTextBox: I recommend to use the String.Format function. This allows you to create strings with different values, but is much, much easier to read.
For the titles: Use your variable hdr This should contain the title. Then you can split it via string.Split(',') or string.Split(';'), depending on your delimiter
I have a method that runs through a loop that can take quite a while to complete as it requires getting data back form an API.
What I would like to do is display a message on the front end explaining how the system is progressing during each loop. Is there a way to update the front end while processing?
public static void GetScreenshot(List<string> urlList, List<DesiredCapabilities> capabilities, String platform, Literal updateNote)
{
foreach (String url in urlList)
{
String siteName = new Uri(url).Host;
String dir = AppDomain.CurrentDomain.BaseDirectory+ "/Screenshots/" + siteName + "/" + DateTime.Now.ToString("yyyy-MM-dd_HH-mm");
foreach (DesiredCapabilities cap in capabilities)
{
String saveDirectory = "";
if (platform == "btnGenDesktopScreens")
{
saveDirectory = dir + "/" + cap.GetCapability("os") + "-" + cap.GetCapability("os_version") + "-" + cap.GetCapability("browser") + cap.GetCapability("browser_version");
}
else if(platform == "btnMobile")
{
saveDirectory = dir + "/" + cap.GetCapability("platform") + "" + cap.GetCapability("device") + "-" + cap.GetCapability("browserName");
}
updateNote.Text += "<br/>" + cap.GetCapability("platform") + " - " + cap.GetCapability("device") + "-" + cap.GetCapability("browserName");
//I'd like to display a message here
TakeScreenshot(url, cap, saveDirectory);
//I'd like to display a message here
}
}
}
Has anyone come across a method of doing this?
Depending on how you're returning the feedback to the user, you might be able to do this by using HttpResponse.Flush in a loop to push parts of the HTML response to the user a bit at a time. See https://msdn.microsoft.com/en-us/library/system.web.httpresponse.flush(v=vs.100).aspx
Here is the offending code. I haven't done much string manipulation yet, and am currently having issues.
if (orderid != orderlist[orderlist.Count - 1])
{
response2 = GetSubstringByString("{\"orderid\": \"" + orderid + "\"", "{\"orderid\": \"", response2);
}
else
{
response2 = GetSubstringByString("{\"orderid\": \"" + orderid + "\"", "success", response2);
}
Console.WriteLine("Response 2 is: " + response2);
logger.Log("Writing " + writepath + filename);
File.WriteAllText(writepath + filename, response2);
}
public string GetSubstringByString(string a, string b, string c) //trims beginning and ending of string
{
Console.WriteLine("String a is: " + a + "String b is: " + b + "String c is: " + c);
return c.Substring((c.IndexOf(a) + a.Length), (c.IndexOf(b) - c.IndexOf(a) - a.Length));
}
I am having issues extracting a substring, as the beginning and ending strings are the same, and therefore it is unable to differentiate the strings from each other.
Here is the main issue:
response2 = GetSubstringByString("{\"orderid\": \"" + orderid + "\"", "{\"orderid\": \"", response2);
Is there a way I can add a check if the orderid for the ending string differs from the starting string orderid? Thanks for any help!
I was working with code that was already set to scan rather than parse JSON in the optimal fashion.
I utilized this regex to remove orderid before each number as to not cause scanner length exceptions. I also overloaded string.IndexOf as mentioned by juharr.
var regex = new Regex(Regex.Escape("orderid")); //replace first occurrence of orderid
response2 = regex.Replace(response2, "", parsecount-1);
public string GetSubstringByString(string a, string b, string c) //trims beginning and ending of string
{
logger.Log("String a is: " + a + "String b is: " + b + "String c is: " + c);
var offset = c.IndexOf(b);
//lastcheck will return 0 if it's last element in orderlist, because ending string differs for last
return c.Substring((c.IndexOf(a) + a.Length), (c.IndexOf(b, offset + lastcheck) - c.IndexOf(a) - a.Length));
}
I'am exporting some data to a .txt file as follows:
String content;
String path=#"e:\coding\";
String name="test.txt";
path+=name;
System.IO.File.Delete(path);
for (i=0;i<row-1;i++)
{
try
{
if (r[i].points.Count() > 2)
{
content = "Route " + (i + 1).ToString() +" Truck_id:"+trk[i].truck_name.ToString()+ " Max_load="+trk[i].capacity.ToString()+ "\n";
System.IO.File.AppendAllText(path, content + Environment.NewLine);
System.IO.File.AppendAllText(path, "Points Load Reached_AT Max_load" + Environment.NewLine);
System.IO.File.AppendAllText(path, "========================================" + Environment.NewLine);
for (int j = 0; j < (r[i].points.Count()); j++)
{
content = r[i].points[j].ToString() + " " + c[r[i].points[j]].load.ToString() +" "+ r[i].time_list[j].ToString()+" "+c[r[i].points[j]].max_load.ToString()+"\n";
System.IO.File.AppendAllText(path, content + Environment.NewLine);
}
content = "Total " + r[i].ld.ToString() + "\n";
System.IO.File.AppendAllText(path, content + Environment.NewLine );
content = "Route Complete: " + r[i].reach_at.ToString();
System.IO.File.AppendAllText(path, content + Environment.NewLine+Environment.NewLine);
}
}
catch (IndexOutOfRangeException e)
{
break;
}
}
As expected the output I get is not properly formatted:
The spaces are causing the text to be jumbled and not arranged. My reputation does'nt allow me to post a screenshot but I guess It can be understood what is happening.
Is there way so that the text is properly formatted neatly column wise without looking jumbled.
If you need a text, you can use tabs:
System.IO.File.AppendAllText(path, "Points\t\tLoad\t\tReached_AT\t\tMax_load" + Environment.NewLine);
// ...
content = r[i].points[j].ToString() + "\t\t " + c[r[i].points[j]].load.ToString() +"\t\t"+ r[i].time_list[j].ToString()+"\t\t"+c[r[i].points[j]].max_load.ToString()+"\n";
Just play with amount of tabs (\t for one, \t\t for two, etc...). Hope it can help.
Another solution would be to use commas:
System.IO.File.AppendAllText(path, "Points,Load,Reached_AT,Max_load" + Environment.NewLine);
and save to CSV-file (comma-separated values). Then you can import the data to Microsoft Excel or to other software.
You can find bunch full of good information on how to format the string contents in the The format item MSDN but for quick answer, an example for your string
content = "Route " + (i + 1).ToString() + " Truck_id:" + trk[i].truck_name.ToString() + " Max_load=" + trk[i].capacity.ToString() + "\n";
If we assume,
i maximum 10 digits,
Truck_name max 45 characters
capacity max 10 digits
content = String.Format("{0,-20}{1,55}{2,20} " + Environment.NewLine, "Route " + (i + 1).ToString(), " Truck_id:" + trk[i].truck_name.ToString(), " Max_load=" + trk[i].capacity.ToString());
Here's what I've got, I need to keep the console from returning additional commas on the main program, so I probably need to rewrite string e. Month, description etc. should still have commas, but if something like "note" is absent, those additional commas would be gone.
public override string ToString()
{
string e = description + ", " + month + day + year + ", " + amount.ToString("C") + ", ";
e = e + paymentMethod + ", " + trip + ", " + note;
return e;
}
You can try something like this, to filter out empty elements:
public override string ToString()
{
string[] elements = new string[] { description,
String.Concat(month, day, year),
amount.ToString("C"), paymentMethod, trip, note };
return String.Join(", ", elements.Where(s => !String.IsNullOrWhiteSpace(s)));
}
A little more verbose option, but also less confusing and C# 2 compatible:
private static void AddIfNotNull(List<string> elements, string value)
{
if (!String.IsNullOrEmpty(value))
elements.Add(value);
}
public override string ToString()
{
List<string> elements = new List<string>();
AddIfNotNull(elements, description);
elements.Add(String.Concat(month, day, year));
elements.Add(amount.ToString("C"));
AddIfNotNull(elements, paymentMethod);
AddIfNotNull(elements, trip);
AddIfNotNull(elements, note);
return String.Join(", ", elements.ToArray());
}
You could rewrite ToString like this, is that what you want?
public override string ToString()
{
string e = description + " " + month + day + year + " " +
amount.ToString("C") + " ";
e = e + paymentMethod + " " + trip + " " + note;
return e;
}
