    <p>i have written a little "Update Programm" to keep an .exe up to date for the rest of my dev team. It used to work fine, but suddenly it stopped working.</p> <p>I already noticed the problem: my remote stream does not start to read.</p> <pre><code> Uri patch = new Uri("http://********/*********/" + GetVersion().ToString() + ".exe"); Int64 patchsize = PatchSize(patch); var CurrentPath = String.Format("{0}\\", Environment.CurrentDirectory); Int64 IntSizeTotal = 0; Int64 IntRunning = 0; string strNextPatch = (version + ".exe"); using (System.Net.WebClient client = new System.Net.WebClient()) { using (System.IO.Stream streamRemote = client.OpenRead(patch)) { using (System.IO.Stream streamLocal = new FileStream(CurrentPath + strNextPatch, FileMode.Create, FileAccess.Write, FileShare.None)) { int intByteSize = 0; byte[] byteBuffer = new Byte[IntSizeTotal]; while ((intByteSize = streamRemote.Read(byteBuffer, 0, byteBuffer.Length)) &gt; 0) { streamLocal.Write(byteBuffer, 0, intByteSize); IntRunning += intByteSize; double dIndex = (double)(IntRunning); double dTotal = (double)byteBuffer.Length; double dProgressPercentage = (dIndex / dTotal); int intProgressPercentage = (int)(dProgressPercentage * 100); worker.ReportProgress(intProgressPercentage); } streamLocal.Close(); } streamRemote.Close(); </code></pre> <p>GetVersion() only returns the current version number of the current server version of the .exe. The problem lies here:</p> <pre><code>while ((intByteSize = streamRemote.Read(byteBuffer, 0, byteBuffer.Length)) &gt; 0) </code></pre> <p>My streamRemote just does not return any bytes so this while clause is not filled.</p> <p>Any advice for me?</p>

    1. COUnrelated to your problem, but you can remove the redundant Close() calls - that's what the using statements are for. You can also stack all your usings on top of each other and have you block at one level of indentation.

    2. COThank you! I did this to get a little more 'overview' into my code.

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).
