    <p>I have a batch file that I need to run within my NSIS installer. It must run after all the files have been extracted, (I suppose this is obvious, otherwise the batch file wouldn't exist yet).</p> <p>I tried to use MUI_PAGE_CUSTOMFUNCTION_PRE with the finish page in order to run it but when it gets to that portion of the script it appears that it skips right over it. Below is how I invoke it.</p> <pre><code>;;Finish Page !define MUI_PAGE_CUSTOMFUNCTION_PRE Done !insertmacro MUI_PAGE_FINISH Function Done ExecWait '"$INSTDIR\BatchFile" "$INSTDIR" "$DATA_FOLDER"' FunctionEnd </code></pre> <p>Thanks in advance for your help.</p> <p><strong><em>UPDATE</em></strong></p> <p>I have now tried using the following: </p> <pre><code>ExpandEnvStrings $0 %COMSPEC% ExecWait '"$0" /C "$INSTDIR\batch.bat" "$INSTDIR" "$DATA_FOLDER"' </code></pre> <p>This did not work, so I took out the /C to see what the cmd prompt was saying (it is popping up, but closing immediately) and it seems as though it executes cmd.exe but that's it, it doesn't complete the rest of the execute.</p> <p><strong><em>UPDATE #2</em></strong></p> <p>The core knowledge that led to me getting it to work can be found here:</p> <p><a href="https://stackoverflow.com/questions/148968/windows-batch-files-bat-vs-cmd">Windows batch files: .bat vs .cmd?</a></p> <p>For whatever reason .bat files do not agree with ExecWait.</p> <p>In the end:</p> <pre><code>ExecWait '"$INSTDIR\BatchFile.cmd" "$INSTDIR" "$DATA_FOLDER"' </code></pre> <p>Worked just fine.</p>

    1. COI was able to run .bat file, just as you've posted above for cmd files. You can also suppress the command window from being displayed by using nsExec::Exec, rather than ExecWait.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
