Use Find to obtain the index in a sorted list where the string S should be added.
If the string S, or a string that differs from S only in case when CaseSensitive is false, already exists in the list, Find returns true. If the list does not contain a string that matches S, Find returns false. The index where S should go is returned in the Index parameter.
The value of Index is zero-based, where the first string has the index 0, the second string has the index 1, and so on. Note: Only use Find with sorted lists. For unsorted lists, use the IndexOf method instead. Collapse All. When the application runs, a string list object is created and three strings are added to it. Create; try MyList. Add 'Animals' ; MyList. Add 'Flowers' ; MyList. Add 'Cars' ; MyList.
Find 'Flowers', Index then begin ListBox1. AddStrings MyList ; Label1. Free; end ; end. See Also.

Send feedback!This topic contains information about handling strings in DelphiScript and provides examples of operations that deal with strings. It contains the following sections:. Special characters. Getting the string length. Concatenating strings. Comparing strings. Accessing individual character of a string.
Searching for characters and substrings. Getting a substring. Splitting strings. Removing extra spaces from a string. Replacing characters and substrings. Changing the letter case. Working with string lists. A string is a sequence of symbols or digits.
Strings are among the most frequently used data types. In DelphiScript, a sequence of literal characters enclosed in single quotation marks ' is recognized as a string. Double quotation marks " are allowed within a string.
To insert a single quotation mark into a string, it should be duplicated. The following is an example of string:.Using String grids in Delphi
Is there anyone? To deal with strings, TestComplete has a special aqString scripting object. The object is available for all supported scripting languages, so that you can use it to operate with string values regardless of the chosen language.
Another scripting object that is useful for string manipulation is aqConvert. This object has several methods that convert values of different types to a string representation and vice versa. Furthermore, you can use native DelphiScript functions that operate with strings. The table below lists these functions:. This also applies to special characters that are used to format string values. The table below lists the most frequently used special characters.
Characters returned by Chr function should be joined to the string by concatenation :. The symbol notation can be used both in concatenation with a string and within the string text when enclosed in single quotation marks :.Forums New posts Search forums.

Joined Jun 29, Messages 5, Please, tell us if it worked as you want. I hope it helps. I've gone through this formula multiple times and I'm just not understanding it.In the last article, we covered the basics of the Excel Find and Replace dialog. In many situations, however, you may want Excel to find and extract data from other cells automatically based on your criteria.
So, let's have a closer look at what the Excel search functions have to offer. Is syntax and arguments are akin to those of FIND:. Further on in this tutorial, you will find a few more meaningful formula examples that demonstrate how to use SEARCH function in Excel worksheets. However, they do have a couple of differences.
To see how it works on real data, consider the following example:. This example shows how you can find and extract all characters in a text string to the left or to the right of a specific character. To make things easier to understand, consider the following example. Supposing you have a column of names column A and you want to pull the First name and Last name into separate columns. As you probably know, the Excel LEFT function returns the specified number of left-most characters in a string.
At that, you subtract 1 from the space's position because you don't want the returned value to include the space. The LEN function is needed to get the total number of characters in the string, from which you subtract the position of the space:.
String Types (Delphi)
The following screenshot demonstrates the result:. For more complex scenarios, such as extracting a middle name or splitting names with suffixes, please see How to split cells in Excel using formulas. Supposing you have some text strings in column A, say a list of SKUs, and you want to find the position of the second dash - in a string. The following formula works a treat:. The first two arguments are easy to interpret: locate a dash "-" in cell A2. Instead of CHAR 1 you can use any other unprintable character from 1 to And then, the FIND function returns the position of that character in the text string.
So, the general formula is as follows:. At first sight, it may seem that the above formulas have little practical value, but the next example will show how useful they are in solving real tasks. The following example demonstrates how you can use such formulas in practice.
In our list of SKUs, supposing you want to find the first 3 characters following the first dash and pull them in another column. If the group of characters preceding the first dash always contains the same number of items e.Posted by Jenny on June 18, In Reply to: plz help me posted by mido on June 13, : hello there : i've create a table in a form,i want 2 make a seach button in this table,exp :i want 2 make a search for the Book beginning in letter A or else,wat is the procedure :plz help me,10x 4 u The Delphi table must be indexed on the field "Book".
You find the first record where this field starts with A: Table1. FindNearest ['A'] ; If there is no index on a field, it's not possible. You could go through all the records, or use the Locate method, but that would not give you the FIRST book in alphabetical order that starts with an A.
