I have a textbox1 that lets the user input a text, a button that adds the text to textbox2.
this is my code but it doesnt create a new line when I add another text.
string date = DateTime.Now.ToString();
txt_details.Text = date + " " + txt_summary.Text.ToString() + Environment.NewLine + Environment.NewLine ;
Notice the += operator.
txt_details.Text += "\n" + date + " " + txt_summary.Text.ToString();
Looks like you should be appending (use +=); instead you are overwriting.
string date = DateTime.Now.ToString();
txt_details.Text += date + " " + txt_summary.Text.ToString() + Environment.NewLine + Environment.NewLine
Make sure Multiline is enabled.
Ensure that TextBox.Multiline property is set to true
txt_details.Multiline = true;

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 am trying to get a snippet of HTML between to comments.
I will need to parse the HTML between the start/end later.
I am actually reading from an html file but for test purposes I mocked the following up:
string emailFeedTxtStart = "<!--FEED FOR RECEIPT GOES HERE-->";
string emailFeedTxtEnd = "<!--FEED FOR RECEIPT ENDS HERE-->";
string html =
emailFeedTxtStart + Environment.NewLine +
#"<td align=""center"">" + Environment.NewLine +
#"<table style=""table-layout:fixed;width:380px"" border=""0"" cellspacing=""0"" cellpadding=""0"">" + Environment.NewLine +
"<tbody>" + Environment.NewLine +
"<tr>" + Environment.NewLine +
"<td>" + Environment.NewLine +
"</td>" + Environment.NewLine +
"</tr>" + Environment.NewLine +
"</tbody>" + Environment.NewLine +
"</table>" + Environment.NewLine +
"</td>" + Environment.NewLine +
emailFeedTxtEnd;
string patternstart = Regex.Escape(emailFeedTxtStart);
string patternend = Regex.Escape(emailFeedTxtEnd);
string regexexpr = patternstart + #"(.*?)" + patternend;
//string regexexpr = #"(?<=" + patternstart + ")(.*?)(?=" + patternend + ")";
MatchCollection matches = Regex.Matches(#html, #regexexpr);
matches returned is 0.
(note there is a lot more HTML between the ).
Any help would be greatly appreciated.
What are you going to parse the HTML with after? Because there's probably a way you can just do away with actually manipulating the HTML string beforehand. Here's a solution anyway:
string afterFirst = html.Substring(Regex.Match(html, emailFeedTxtStart).Index + emailFeedTxtStart.Length);
string between = afterFirst.Substring(0, Regex.Match(afterFirst, emailFeedTxtEnd).Index);
When trying to create an iCal file I get a very strange issue that I cannot trace. The following is the code used and an example of an event that is set to start at 08:00 and end at 11:00. The file creates with relevant information, but when tryting to add it to Outlook an hour has been added to the end time.
DateTime eventDate = DateTime.Parse("19/06/2014");
DateTime startTime = DateTime.Parse("09:00:00");
DateTime endTime = DateTime.Parse("11:00:00");
string location = "Test Location";
string title = "Test Title";
context.Response.ContentType = "text/x-vcalendar";
string filename = String.Format("attachment; filename={0}.ics", eventname.Replace(" ", "-"));
context.Response.AddHeader("Content-disposition", filename);
context.Response.Write("BEGIN:VCALENDAR" + Environment.NewLine);
context.Response.Write("VERSION:2.0" + Environment.NewLine);
context.Response.Write("METHOD:PUBLISH" + Environment.NewLine);
context.Response.Write("BEGIN:VTIMEZONE" + Environment.NewLine);
context.Response.Write("TZID:Europe/London" + Environment.NewLine);
context.Response.Write("X-LIC-LOCATION:Europe/London" + Environment.NewLine);
context.Response.Write("BEGIN:DAYLIGHT" + Environment.NewLine);
context.Response.Write("TZOFFSETFROM:+0000" + Environment.NewLine);
context.Response.Write("TZOFFSETTO:+0100" + Environment.NewLine);
context.Response.Write("TZNAME:BST" + Environment.NewLine);
context.Response.Write("DTSTART:19700329T010000" + Environment.NewLine);
context.Response.Write("RRULE:FREQ=YEARLY;BYMONTH=3;BYDAY=-1SU" + Environment.NewLine);
context.Response.Write("END:DAYLIGHT" + Environment.NewLine);
context.Response.Write("BEGIN:STANDARD" + Environment.NewLine);
context.Response.Write("TZOFFSETFROM:+0100" + Environment.NewLine);
context.Response.Write("TZOFFSETTO:+0000" + Environment.NewLine);
context.Response.Write("TZNAME:GMT" + Environment.NewLine);
context.Response.Write("DTSTART:19701025T020000" + Environment.NewLine);
context.Response.Write("RRULE:FREQ=YEARLY;BYMONTH=10;BYDAY=-1SU" + Environment.NewLine);
context.Response.Write("END:STANDARD" + Environment.NewLine);
context.Response.Write("END:VTIMEZONE" + Environment.NewLine);
context.Response.Write("BEGIN:VEVENT" + Environment.NewLine);
context.Response.Write("ORGANIZER:MAILTO: test#domain.com" + Environment.NewLine);
context.Response.Write("UID: test2#domain.com" + Environment.NewLine);
context.Response.Write("DTSTART:" + startDate.ToUniversalTime().ToString("yyyyMMddTHHmmssZ") + Environment.NewLine);
context.Response.Write("DTEND:" + GetMeetingEndDate(startDate, endDate).ToString("yyyyMMddTHHmmssZ") + Environment.NewLine);
context.Response.Write("DTSTAMP:" + DateTime.Now.ToUniversalTime().ToString("yyyyMMddTHHmmssZ") + Environment.NewLine);
context.Response.Write("SUMMARY:" + subject + Environment.NewLine);
context.Response.Write("DESCRIPTION:" + description + Environment.NewLine);
context.Response.Write("LAST-MODIFIED:" + DateTime.Now.ToUniversalTime().ToString("yyyyMMddTHHmmssZ") + Environment.NewLine);
context.Response.Write("PRIORITY:5" + Environment.NewLine);
context.Response.Write("LOCATION;ENCODING=QUOTED-PRINTABLE:" + location + Environment.NewLine);
context.Response.Write("CLASS:PUBLIC" + Environment.NewLine);
context.Response.Write("END:VEVENT" + Environment.NewLine);
context.Response.Write("END:VCALENDAR");
The outcome of this is for the appointment to be added to Outlook with a start time of 09:00 and an end time of 12:00. The end time has increased by one hour.
Please note that the code about is intended for British/GMT use.
I have debugged this procedure and checked all the dates as they are being set and everything is correct. Is there anything that I am missing with this? I really don't want to have to force a reduction in the end hour just so it adds properly to Outlook.
Edit:
The following is the GetMeetingEndDate function.
DateTime GetMeetingEndDate(DateTime startDate, DateTime endDate)
{
DateTime newDate = new DateTime();
if (endDate < startDate)
{
newDate = endDate.AddHours(12);
}
else if (endDate == startDate)
{
newDate = startDate.AddDays(1).AddHours(-1);
}
else
{
newDate = endDate;
}
return newDate;
}
Thank you.
In the below code:-
context.Response.Write("DTSTART:" + startDate.ToUniversalTime().ToString("yyyyMMddTHHmmssZ") + Environment.NewLine);
context.Response.Write("DTEND:" + GetMeetingEndDate(startDate, endDate).ToString("yyyyMMddTHHmmssZ") + Environment.NewLine);
the DTSTART is set to value startDate.ToUniversalTime() whereas in function GetMeetingEndDate the dates are passed without converting into UTC. Because of this startdate is always correct but iCal is treating your local enddate as UTC date. That might be causing the problem of adding extra hour. The solution is to change the below code block as
context.Response.Write("DTEND:" + GetMeetingEndDate(startDate.ToUniversalTime(), endDate.ToUniversalTime()).ToString("yyyyMMddTHHmmssZ") + Environment.NewLine);
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());
I wrote this function
private void richAdd(string who, string what)
{
string colorstring = who + " ( " + DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss") + " ) :";
richTextBox1.Text += colorstring + " " + what + "\r\n\r\n";
richTextBox1.DeselectAll();
richTextBox1.Select(richTextBox1.Find(colorstring), colorstring.Length);
richTextBox1.SelectionColor = Color.Blue;
richTextBox1.DeselectAll();
}
which is supposed to color who+time in blue and what in black.
Yet after the second time it makes all the text blue... any ideas what could be wrong with it?
Thanks!
try
private void richAdd(string who, string what)
{
string colorstring = who + " ( " + DateTime.Now.ToString("dd/MM/yyyy HH:mm:ss") + " ) :";
richTextBox1.AppendText(colorstring + " " + what + "\r\n\r\n");
richTextBox1.Select(richTextBox1.Text.LastIndexOf(colorstring), colorstring.Length);
richTextBox1.SelectionColor = Color.Blue;
}
