<h1><a name="CRC-String">C.1 CRC-String</a></h1>
|
|
<p>Selecting this option, a checksum is written both to the
|
|
resource itself (as a free string) and the header file. This can be
|
|
used by a program to determine whether the correct resource file has
|
|
been loaded.
|
|
</p>
|
|
<p>Whether a CRC string is stored, can be specified in <a href="output.html">File/Output files</a> with
|
|
the option <b>CRC-String</b>.
|
|
</p>
|
|
<p>The export uses following variables:
|
|
</p>
|
|
<table class="UDO_env_xlist">
|
|
<tr><td nowrap="nowrap" valign="top">_RSM_CRC_:</td>
|
|
<td valign="top"> Index of the free string containing the CRC-string
|
|
</td></tr>
|
|
|
|
<tr><td nowrap="nowrap" valign="top">_RSM_CRC_STRING_:</td>
|
|
<td valign="top"> CRC-String value (should match the string from the resource)
|
|
|
|
</td></tr>
|
|
</table>
|
|
|
|
<p>Note: The CRC-string can be used to check wether a resource file
|
|
has been changed in an incompatible way. For the calculation of the
|
|
checksum, object types, object numbers and their links are used, but
|
|
not texts and positioning.
