    <p>I am trying to compare wxstrings to determine what my program will do. The string I am comparing is based on a file I am reading in and is the only line in the file.</p> <p>I am using codeblocks with wxSmith activated.</p> <p>This is the section of my program that I am trying to get working.</p> <pre><code>void Disc_MasterFrame::OncdiscClick(wxCommandEvent&amp; event) { system("sh detect-disc.sh"); wxString file; file &lt;&lt; wxT("detect-disc"); wxTextFile tfile; tfile.Open(file); detectdiscw=tfile.GetFirstLine(); //std::ifstream myfile ("detect-disc"); //getline (myfile,detectdisc); //myfile.close(); cd &lt;&lt; wxT("An audio cd was inserted."); dvd &lt;&lt; wxT("A dvd was inserted."); if (detectdiscw == cd){ //musicrip-&gt;Show(); //this-&gt;Disc_MasterFrame::ripmusic(); void ripmusic(); } else if (detectdiscw == dvd) { manipdvd-&gt;Show(); void dvdmanip(); } } void Disc_MasterFrame::ripmusic() { musicrip-&gt;Show(); system("sh disc-info.sh"); ... </code></pre> <p>When the button is clicked, the script should run, it does because it generates a file using the cdde command (linux/ubuntu cli program). The result of this command is "An audio cd was inserted." so I have consistency when testing.</p> <p>Then it opens and reads the file and attempts to compare it to two predefined strings. Once that is done it should 'show' one of two panels already created.</p> <p>I pretty sure I'm doing something wrong because it just sits there after the button is clicked. </p> <p>Any help or direction would be greatly appreciated, thanks.</p>

    1. COThat seems like a frustrating problem. Have you stepped through the code with a debugger? This will often show you exactly where the code is going wrong and even make the fix obvious. Try it and let us know where the problem is.

    2. COWhy do you have `void` before your calls to `ripmusic` and `dvdmanip`? If your ignoring return values, you should use `(void)` to cast the return value (note the parens).

    3. COTry adding a *print* statement inside a final `else` clause. You could better see the issue if you converted your `if`-`then` ladder to a `switch` statement. In other words, what happens if the value of `detectdiscw` is not cd or dvd but something else?

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.
