    <p>I have a new laptop at work and code that worked earlier in the week does not work today.</p> <p>The code that worked before is, simplified: </p> <pre><code>while (dr.Read()) { int i = int.Parse(dr.GetString(1)) } </code></pre> <p>Now it fails when the database value is 0. Sometimes, but not reliably, this will work instead:</p> <pre><code>while (dr.Read()) { int i = Convert.ToInt32(dr["FieldName"])) } </code></pre> <p>Am I missing something stupid?</p> <p>Oddly enough, ReSharper is also having tons of weird errors with the same error message that I am getting with the above code: "input string was not in the correct format." (Starts before I even load a project.)</p> <p>Any ideas? Anyone having any SP issues? I did try to make sure all my SPs were up-to-date when I got the machine.</p> <p>EDIT: I understand how to use Try.Parse and error-handling. The code here is simplified. I am reading test cases from a database table. This column has only 0, 1, and 2 values. I have confirmed that. I broke this down putting the database field into a string variable s and then trying int.Parse(s). The code worked earlier this week and the database has not changed. The only thing that has changed is my environment.</p> <p>To completely simplify the problem, this line of code throws an exception ("input string was not in the correct format"):</p> <pre><code> int.Parse("0"); </code></pre> <p>EDIT: Thanks to everyone for helping me resolve this issue! The solution was forcing a reset of my language settings.</p>

    3. COIf you create a new application with the sole line of custom executing code being int.Parse("0"); and it is throwing an error, then I think you might have a bigger problem.

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).
