i am running the following code
foreach (ReportObject obj in oSectionObjects)
{
if (obj.Kind == CrystalDecisions.Shared.ReportObjectKind.TextObject)
{
// do stuff
}
}
but i have a problem. i do have multiple text that do contain text AND fields in them.
But crystal return me the field being TextObject which is technically true.
How do i know i ONLY have text in the TextObject and not anything else (aka fields, parameters, formulas) ?
As far as I know the fields in a text box will be recognized by the text pattern. Try to search the text of the text object for {1#xxxxx} where xxxxx is the field name. "{1#" shows the type of the field: 1 is for a database , 2 is for formula, 3 is for parameter. You may try also for {#xxxxx} *(without numeric field identifier)
I searched alot around and found working solution for RAS report but nothing for crystal. Anyhow if someone end up here looking for an answer here's the work around.
Whenever you have to concatenate multiple fields on the report do NOT use TextObject. Instead use a Formula. The formula fields wont bet part of the ReportObjects but instead part of the ReportDocument.DataDefinition.FormulaFields with Kind being CrystalDecisions.Shared.FieldKind.FormulaField and you will want to check the ValueType so it is CrystalDecisions.Shared.FieldValueType.StringField.
then you can manipulate them.
I did need that for translation of report live so here's a parsing method for formulas :
try
{
var sFormula = formula.Text;
string pattern = "\"[\\w ]*\"";
Regex r = new Regex(pattern);
MatchCollection mc = r.Matches(sFormula);
foreach (Match m in mc)
{
var sValue =m.Value;
var sParsedValue = sValue.Substring(1, sValue.Length - 2);
if (sParsedValue.StartsWith("s"))
{
var stest = "\"" + CApplicationData.TranslateStringValue(sParsedValue) + "\"";
sFormula = sFormula.Replace(sValue, stest);
}
}
formula.Text = sFormula;
}
catch{}
this above you will notice i use 's' as a key to know it might be a value to be translated so it's not mandatory. using the above on this formula with Spanish language :
"sPage" + " " + totext(PageNumber) + " " + "sOf" + " " + totext(TotalPageCount)
will modify the formula to :
"Página" + " " + totext(PageNumber) + " " + "de" + " " + totext(TotalPageCount)
giving output of :

I'm having two problems with reading my .csv file with streamreader. What I'm trying to do is get the values, put them into variables which I'll be using later on, inputting the values into a browser via Selenium.
Here's my code (the Console.Writeline at the end is just for debugging):
string[] read;
char[] seperators = { ';' };
StreamReader sr = new StreamReader(#"C:\filename.csv", Encoding.Default, true);
string data = sr.ReadLine();
while((data = sr.ReadLine()) != null)
{
read = data.Split(seperators);
string cpr = read[0];
string ydelsesKode = read[1];
string startDato = read[3];
string stopDato = read[4];
string leverandoer = read[5];
string leverandoerAdd = read[6];
Console.WriteLine(cpr + " " + ydelsesKode + " " + startDato + " " + stopDato + " " + leverandoer + " " + leverandoerAdd);
}
The code in and of itself works just fine - but I have two problems:
The file has values in Danish, which means I get åøæ, but they're showing up as '?' in console. In notepad those characters look fine.
Blank values also show up as '?'. Is there any way I can turn them into a blank space so Selenium won't get "confused"?
Sample output:
1372 1.1 01-10-2013 01-10-2013 Bakkev?nget - dagcenter ?
Bakkev?nget should be Bakkevænget and the final '?' should be blank (or rather, a bank space).
"Fixed" it by going with tab delimited unicode .txt file instead of .csv. For some reason my version of excel doesn't have the option to save in unicode .csv...
Don't quite understand the problem of "rolling my own" parser, but maybe someday someone will take the time to explain it to me better. Still new-ish at this c# stuff...
I am trying to generate code using SyntaxFactory but stuck in converting one area Please see the code below I left comment where I am finding it difficult and used string manipulation.
The idea is there will be two variable removeExpression and getExpression which are of type ExpressionSyntax and finally both will be used to become the body of a anonymous function.
ExpressionSyntax removeExpression = SyntaxGenerator.MethodInvokeExpression(
valueExpression,
"RemoveAt",
BinaryExpression(
SyntaxKind.SubtractExpression,
SyntaxGenerator.PropertyAccessExpression(valueExpression, nameof(Enumerable.Count)),
atExpression
)
);
ExpressionSyntax getExpression = SyntaxGenerator.MethodInvokeExpression(valueExpression, nameof(Enumerable.First));
// Help me to convert the below line using SyntaxFactory.
IdentifierName("((Func<dynamic>)(() => { var res = " + getExpression.ToString() + ";" + removeExpression.ToString() + "; return res" + " ; }))(); ");
right now I am reading some lines from a .txt.
Lets say, a user enters his name and in the .txt will be saved "Logged in {username} on 13/04/2016 at 10:55 am".
(Just an example.)
Now I want to read the .txt and print only specific parts into a textbox.
Meaning, in the textbox shall appear "{Username} - 13/04/2016 - 10:55 am".
So far, I am able to read from the .txt and print the whole line.
private void button_print_results_Click(object sender, RoutedEventArgs e)
{
int counter = 0;
string actual_line;
System.IO.StreamReader file_to_read =
new System.IO.StreamReader("myText.txt");
while ((actual_line = file_to_read.ReadLine()) != null)
{
textBox_results.Text = textBox_results.Text +"\n"+ actual_line;
counter++;
}
file_to_read.Close();
}
Is there a way, to reach this without overwriting the whole file?
And no, I can't change the format how the names etc. are saved.
(I used them here for a better understanding, the actual lines I need to read/check are different and auto-generated).
I don't expect full working code, it would be just great if you could tell me for which commands I need to look. Been a long time since I last worked with c#/wpf and I never worked much with Streamreader...
Thanks
I think regular expressions is the best tool for what you're trying to achieve. You can write something like this:
Regex regex = new Regex("Logged in (?<userName>.+) on (?<loginTime>.+)");
while ((actual_line = file_to_read.ReadLine()) != null)
{
Match match = regex.Match(actual_line);
if (match.Success) {
string loginInfo = string.Format("{0} - {1}", match.Groups["userName"], match.Groups["loginTime"]);
textBox_results.Text = textBox_results.Text +"\n"+ loginInfo;
}
}
There are couple of possible solutions for this. One most straight forward way for your case would be to use Substring and Replace.
Since the earlier string is always Logged in (note the last space) and you simply want to get the rests of the string after the phrase, replacing only the preposition of time words (" on ", " at ") with dash (" - ") you could take advantage on that:
string str = "Logged in {username} on 13/04/2016 at 10:55 am";
string substr = str.Substring(("Logged in ").Length) //note the last space
.Replace(" on ", " - ")
.Replace(" at ", " - ");
In your implementation, this is how it look like:
while ((actual_line = file_to_read.ReadLine()) != null)
{
actual_line = actual_line.Substring(("Logged in ").Length) //note the last space
.Replace(" on ", " - ")
.Replace(" at ", " - ");
textBox_results.Text = textBox_results.Text +"\n"+ actual_line;
counter++;
}
(Note: the solution above assumes the {username} does not contain spaced preposition of time words - which would almost likely be the case for a {username})
You could split the actual_line String so you get an array of Strings. And then fill the Strings you want to show in the TextBox into it.
string[] values = actual_line.Split(' ');
textBox_results.Text = textBox_results.Text + "\n" + values[2] + " " + values[6] + " " + values[7];
The text in the TextBox for example is "{username} 10:55 am"
You can use Regex for better performances as #Dmitry-Rotay suggested in the previous comment, but if you jave a not-so-big file your loop+string manipulations is an acceptable compromise.
Always use Environment.NewLine instead of "\n", it's more portable.
while ((actual_line = file_to_read.ReadLine()) != null)
{
actual_line = actual_line
.Replace(("Logged in "), String.Empty)
.Replace(" on ", " - ")
.Replace(" at ", " - ");
textBox_results.Text = textBox_results.Text
+ System.Environment.NewLine
+ actual_line;
counter++;
}
wassup guys im new to C# coding and i did a search but couldn't find exactly what im looking for. So i have a couple of text-boxes which holds string elements and integers
what i want to do is when these boxes are filled in i want to send a summary of the email to client/customer but the format is whats getting me.
(first, one) are strings equaling different text-boxes
my code is:
emailCompseTask.Body = first + one + Enviroment.NewLine +
second + two + Enviroment.NewLine
and so on problem is which i send thru email it shows something like this:
computer service25.00
instead of:
computer service 25.00
is there a way to add spacing to make this more presentable? or even a better way perhaps thanks in advance guys
try this :
emailCompseTask.Body = first + one + " "+ second + two ;
body takes as HTML input, check here for more spacing option.
I'm a bit confused, but you just want to add some spacing in the output? Just throw some spaces in there like you would another variable.
first + " " + one + Environment.NewLine
+ second + " " + two + Environment.NewLine;
You can use a table
string tableRow = #"<tr>
<td>{0}</td>
<td>{1}</td>
</tr>";
string htmlTable = #"<table>
{0}
</table>";
string rows = "";
// Can do this in a loop
rows += string.Format(tableRow, first, one);
rows += string.Format(tableRow, first, one);
emailComseTask.Body = string.Format(htmlTable, rows);
So I'm working on formatting a string and I need to line it up in a table, but this string has an undetermined number of characters. Is there anyway to have the string be in the same spot for each column? so far I have:
ostring += "Notes\t\t"
+ " : "
+ employees[number].Notes
+ "\t\t"
+ employees[number].FirstNotes
+ "\t\t"
+ employees[number].SecondNotes;
I use a similar fashion on the other rows, but they have a pre-determined number of digits, this however doesn't so I can't use the string modifiers like I would like.
Any ideas on what I need to do?
You can use String.PadRight() to force the string to a specific size, rather than using tabs.
When you are using String.Format item format has following syntax:
{ index[,alignment][ :formatString] }
Thus you can specify alignment which indicates the total length of the field into which the argument is inserted and whether it is right-aligned (a positive integer) or left-aligned (a negative integer).
Also it's better to use StringBuilder to build strings:
var builder = new StringBuilder();
var employee = employees[number];
builder.AppendFormat("Notes {0,20} {1,10} {2,15}",
employee.Notes, employee.FirstNotes, employee.SecondNotes);
You would first have to loop over every entry to find the largest one so you know hoe wide to make the columns, something like:
var notesWidth = employees.Max(Notes.Length);
var firstNotesWidth = employees.Max(FirstNotes.Length);
// etc...
Then you can pad the columns to the correct width:
var output = new StringBuilder();
foreach(var employee in employees)
{
output.Append(employee.Notes.PadRight(notesWidth+1));
output.Append(employee.FirstNotes.PadRight(firstNotesWidth+1));
// etc...
}
And please don't do a lot of string "adding" ("1" + "2" + "3" + ...) in a loop. Use a StringBuilder instead. It is much more efficient.
