    <p>I have a <strong>C++</strong> file with some exported functions which I am calling in C#. One of the functions is this:</p> <pre><code>char segexpc[MAX_SEG_LEN]; extern "C" QUERYSEGMENTATION_API char* fnsegc2Exported() { return segexpc2; } </code></pre> <p>Somewhere in the program, I am also doing this thing:</p> <pre><code>if(cr1==1) { strcpy(segexpc, seg); } </code></pre> <p>In my <strong>C#</strong> program, I am invoking the above by the followign way:</p> <pre><code>[DllImport("QuerySegmentation.dll", EntryPoint = "fnsegcExported", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Ansi)] public static extern StringBuilder fnsegcExported(); </code></pre> <p>this.stringbuildervar = fnsegcExported();</p> <p>Previously, I was not getting any error, but now suddenly I have started getting this error, when I debug in visual studio.</p> <pre><code>Windows has triggered a breakpoint in SampleAppGUI.exe. This may be due to a corruption of the heap, which indicates a bug in SampleAppGUI.exe or any of the DLLs it has loaded. This may also be due to the user pressing F12 while SampleAppGUI.exe has focus. </code></pre> <p>This error appears only at the end just before it has to display the window. I have not pressed any F12 key key and neither is any breakpoint set here, but I am not sure why the error is occuring and breaking at this point. <code>this.stringbuildervar = fnsegcExported();</code><br/> When I press on continue, the window appears with the correct output.</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
