For more information, see How to: Read From Text Files with Multiple Formats. The line 'NUMBER OF CARTESIAN GAUSSIAN BASIS FUNCTIONS ' is unique to each file ie, if I open the file in a text editor and search using this string, I only return this one line. Answer (1 of 2): In hieroglyphics, the simple line-diagrams depict simple activities like hunting an animal, chasing it, throwing a weapon, eating, having a get-together with the herd, sleeping, running, etc.

The PeekChars method of the TextFieldParser object can be used to check each field before reading it, allowing you to define multiple formats for the fields and react accordingly. I want to harvest the number of basis functions (210 in this example) and the total amount of CPU times. When such exceptions are thrown, the ErrorLine and ErrorLineNumber properties hold the text causing the exception and the line number of that text. If a field does not match the specified format, a MalformedLineException exception is thrown. Once the format is defined, you can loop through the file, using the ReadFields method to process each line in turn.

This example uses the SetFieldWidths method to define the columns of text: the first column is 5 characters wide, the second is 10, the third is 11, and the fourth is of variable width. In such cases, you need to define the TextFieldType as FixedWidth and define the widths of each field, as in the following example. Other text files may have field widths that are fixed. Define TextFieldType and the delimiter, as in the following example, which uses the SetDelimiters method to define a tab-delimited text file: testReader.SetDelimiters(vbTab) Text files may have fields of various width, delimited by a character such as a comma or a tab space.

Parsing a text file with TextFieldParser is similar to iterating over a text file, while the parse method to extract fields of text is similar to string manipulation methods used to tokenize delimited strings. The TextFieldParser object allows you to parse and process very large file that are structured as delimited-width columns of text, such as log files or legacy database information.
