    <p>I'm curious why I'm having trouble with this function. I'm downloading a PNG file on the web to a destination path. For example, downloading the Google image to the C: drive:</p> <p>netDownloadData("<a href="http://www.google.com/intl/en_ALL/images/srpr/logo1w.png" rel="nofollow noreferrer">http://www.google.com/intl/en_ALL/images/srpr/logo1w.png</a>", "c:\file.png");</p> <p>The file size is correct after downloading. Nothing returning false. When I try opening it it won't show the image. Any ideas are helpful. Thanks!</p> <p>Here's the code: </p> <pre><code>bool netDownloadData(const char *strSourceUrl, const char *strDestPath) { HINTERNET hINet = NULL; HINTERNET hFile = NULL; char buffer[1024]; DWORD dwRead; String sTemp; FILE *fp = NULL; DWORD size = 0; // Open a new internet session hINet = netInit(); if (hINet == NULL) { sprintf(buffer, "Initializing WinINet failed.", strSourceUrl); utilLog(buffer); netCloseHandle(hINet); return false; } // Open the requested url. hFile = netOpenUrl(hINet, strSourceUrl); if (hFile == NULL) { sprintf(buffer, "URL failed upon loading: %s\n", strSourceUrl); utilLog(buffer); netCloseHandle(hINet); return false; } // Read file. while (InternetReadFile(hFile, buffer, 1023, &amp;dwRead)) { if (dwRead == 0) break; buffer[dwRead] = 0; sTemp += buffer; size += dwRead; } // Load information to file. fp = fopen(strDestPath, "wb"); if (fp == NULL) return false; fwrite(sTemp, size, 1, fp); fclose(fp); InternetCloseHandle(hFile); InternetCloseHandle(hINet); return true; } </code></pre>

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.
