Displays a customizable message in the trace window opened in parallel with the current window.
Remark: Like Trace, TraceBuild can be used in the development phase to check that the program is running correctly. In the editor, the "Debugger trace" pane displays the information found in the trace window as well as the full text of errors that occurred.
Example
// Display an error message in the trace window
TraceBuild("The customer code %1 does not exist.", nCustomerCode)
Syntax
TraceBuild(<Initial string> [, <Parameter 1> [... [, <Parameter N>]]])
<Initial string>: Character string
Character string to display. This string contains optional parameters (%1 to %n). To display the % character, this character must be typed twice (%%).
<Parameter 1>: Optional character string
First parameter that will be inserted into the formatted character string.
<Parameter 1> will replace the %1 character, <Parameter 2> will replace the %2 character, etc.
The number of specified parameters must be equal to or greater than the number of parameters used in <Initial string>.
If <Initial string> contains more parameters, the additional parameters will be replaced with empty strings.
<Parameter N>: Optional character string
Nth parameter that will be inserted into the formatted character string.
<Parameter 1> will replace the %1 character, <Parameter 2> will replace the %2 character, etc.
The number of specified parameters must be equal to or greater than the number of parameters used in <Initial string>.
If <Initial string> contains more parameters, the additional parameters will be replaced with empty strings.
Remarks

Using TraceBuild in the multilingual applications

In a multilingual application, TraceBuild can be used to simplify the translation process:
  • the translator translates the message by using the "%1", "%2" characters, ... at the relevant location according to the language.
  • the optional characters can be replaced in all the supported languages.

Use conditions according to the platforms

Linux TraceBuild can be used to display the requested information in a file only. By default, this file is created in the UNIX temporary directory and is named "Trace_<Project>.txt".

Trace window

  • The trace window opens automatically the first time TraceBuild is called (TraceStart is executed automatically). By default, this window is opened in the upper-left corner of the screen.
  • The operating mode of TraceBuild is equivalent to InfoBuild but the display is performed in a parallel window, without waiting for user validation.

Context menu of the trace window

The context menu of the Trace window allows you to:
  • copy/cut/paste the content of trace window.
  • save the content of the trace window in a text file.
    Caution: This option is available only if the wdxxxstd.dll library is on the end-user computer.
  • clear the contents of the trace window.
  • open the trace window on top of all the other windows (including the windows from the other applications).
  • save the size and position of the trace window when it is closed. When this window is displayed again, it will keep the size and position saved.
  • display an horizontal scrollbar.
  • display special characters in gray or use them directly: EOT, TAB, etc. Therefore, the "Carriage Return" (CR) characters found correspond to "<\r><\n>".
    Remark: This option will be taken into account from the next line of information displayed.
