Generic search

We are now going to perform a generic search. Instead of searching for the exact value that was entered, we are going to search for all the elements that start with the value entered.
To perform this search, we will create an Edit control to enter the name you are looking for, and a Button control to launch the search.
  • To create the search control:
    1. Display (if necessary) the "Finding customers" pane tab of "WIN_Menu" in the editor.
    2. Create an edit control: on the "Creation" pane, in the "Usual controls" group, click Creating an edit control.
    3. In the window, click below the Combo Box control ("Sought customer"). The edit control is created.
    4. This control is named "EDT_Sought_Name" and its caption is "Sought name".
  • To create the Button control to launch the generic search:
    1. Create a Button control: on the "Creation" pane, in the "Usual controls" group, click Create a Button control.
    2. Position the control beside the edit control that was just created.
      Search interface
    3. This control is named "BTN_GenericSearch" and its caption is "Generic search".
    4. If necessary, adjust the size of the control so that the caption is displayed properly in the control.
    5. Write the following WLanguage code in the "Click" event of the button:
      // Finds a customer from his name
      HReadSeek(Customer, FullName, EDT_Sought_Name)
      IF HFound(Customer) THEN
      // Displays the customer data
      FileToScreen()
      ELSE
      Error("No customer matches")
      END
      HReadSeek is used to perform a generic search. In this example, the search is performed on the "Customer" data file and on the "FullName" item. The sought value corresponds to the value typed in the "EDT_Sought_Name" control. This value is obtained by using the control name.

      Remark

      		To perform an exact-match search, call HReadSeek: to do so, the hIdentical constant must be used.
    6. Close the code window.
    7. Save the window (Ctrl + S).
  • Let's run a window test:
    1. Run the window test ( Run the test of a window among the quick access buttons).
    2. Click the "Finding customers" tab pane if necessary.
    3. Enter a value in the edit control (for example "BEEF") and click "Generic search".
      Test for the generic search
    4. The result is immediate. However, if several records correspond to the search, only the first one is displayed.
    5. Stop the test and go back to the editor.
