One way would be to create a FileStream with the FileMode.Append creation mode. Opens the file if it exists and seeks to the end of the file, or creates a new file. This would look something like: public static void AppendAllBytes(string path, byte[] bytes) { //argument-checking here. using (var stream = new FileStream(path, FileMode.Append)) { … Read more
Use TEXTJOIN() instead: =TEXTJOIN(“;”,TRUE,A1:A2000) For those who do not have OFFICE 365 Excel then use this UDF that mimics the TEXTJOIN Function. Put this in a module attached to the workbook and use the formula above to call. Function TEXTJOIN(delim As String, skipblank As Boolean, arr) Dim d As Long Dim c As Long Dim … Read more

For readability, I’d go with char * s = malloc(snprintf(NULL, 0, “%s %s”, first, second) + 1); sprintf(s, “%s %s”, first, second); If your platform supports GNU extensions, you could also use asprintf(): char * s = NULL; asprintf(&s, “%s %s”, first, second); If you’re stuck with the MS C Runtime, you have to use … Read more
You can’t have multiple lines in a text box, you need a textarea. Then it works with \n between the values.
