# KVHTMLSetStyleSheet()

This function is called directly and is used to specify the full path and file name of an external Cascading Style Sheet (CSS).

NOTE: You cannot retrieve the CSS if you have set `bNoPictures` to TRUE (see KVHTMLOptionsEx).

## Syntax

    BOOL pascal KVHTMLSetStyleSheet(
        void    *pContext,
        char    *pszStyleSheetName,
        char    *pszUrlRef);

## Arguments

`pContext` | A pointer to an Export session that you initialized by calling fpInit().
`pszStyleSheetName` | A pointer to the full path and file name of the style sheet.
`pszUrlRef` | A pointer to the URL or file name of style sheet.

## Returns

- If the call is successful, the return value is `TRUE`.

- If this call is unsuccessful, the return value is `FALSE`.

## Discussion

- When the value for `eStyleSheetType` in `KVHTMLOptionsEx` is set to CSS_TOFILE, and the token `$STYLESHEET` is specified in the templates, an external CSS file is referenced in the output HTML by a LINK statement of the form:

      <LINK rel="STYLESHEET" href="pszRef" type="text/css">

- If the name of the style sheet is not specified by using this function, a style sheet file is created with an automatically generated file name.

- If this function is used to specify the name of the style sheet file, that file name is used in the conversion.

  - If the file does not exist in the specified location, it is created.

  - If the file exists, but is empty, CSS styles are written to the file.

  - If the file exists and is not empty, the conversion attempts to use the predefined styles, and appends any new styles that are required for the conversion.

- If the value for `pszStyleSheetName` includes the output directory, the `href` only consists of the file name because the HTML output resides in the same directory as the CSS file.

- If the value for `pszStyleSheetName` points to a directory other than the output directory, the `href` consists of the full path and file name.

- If the value for `pszStyleSheetName` points to a file that is not a CSS file or to a non-existent directory, the LINK statement is written; but, the style sheet information is added inline (`CSS_INLINE`), and an external CSS file is not generated.

- If there are multiple calls made to `fpConvertStream()` or `KVHTMLConvertFile()`, and the name of the style sheet is set with `KVHTMLSetStyleSheet`, the file name can be disabled by calling `KVHTMLSetStyleSheet` again with the `pszStyleSheetName` and `pszUrlRef` set to `NULL`. The file name can then be set to a different value by calling `KVHTMLSetStyleSheet` with the new file name prior to the next call to `fpConvertStream()` or `KVHTMLConvertFile()`.

- This function runs in-process or out-of-process. See Convert Files Out-of-Process.

- When converting out-of-process, this function must be called after the call to `KVHTMLStartOOPSession()` and before the call to `KVHTMLEndOOPSession()`. See KVHTMLStartOOPSession() and KVHTMLEndOOPSession().

- On Windows, `pszStyleSheetName` must be in the local Windows code page.
