copied!<p>You're opening the file in read-only mode: <code>fopen("C:\\Users\\sshekha\\Desktop\\z.txt","r");</code>. Here <code>"r"</code> says you only intend to read from file. To be able to write contents (i.e. <code>fputs(...)</code>), open the file in write mode like so: fopen("C:\Users\sshekha\Desktop\z.txt","w")<code>(or</code>"a"` if you want to append). For more information, <a href="http://www.cplusplus.com/reference/cstdio/fopen/" rel="nofollow noreferrer">read fopen documentation</a>.</p> <p>EDIT: I see that you've tried both read and write modes. You're code only shows read-mode and hence my assumption on the read-only problem. Let me do a bit more research and get back.</p> <p>Please write the following code in your <code>if</code> statement:</p> <p><code>perror("The following error occurred:");</code></p> <p>if you don't have a console, use this to store the error string:</p> <p><code>char* errorCause = strerror(errno); MessageBoxA(m_hwndPreview, errorCause, "BTN WND", MB_ICONINFORMATION);</code></p> <p>and let us know what you see as the cause.</p> <p>EDIT 2: Since you've mentioned that you're using Visual Studio 2010, are you running it as yourself? This stackoverflow answer shows that VS2010 has different options when debugging applications; <a href="https://stackoverflow.com/a/3704942/210634">https://stackoverflow.com/a/3704942/210634</a></p> <p>NOTE: That feature is only available on 'Pro' versions.</p> <p>Here's a working example: <a href="https://ideone.com/hVLgc4" rel="nofollow noreferrer">https://ideone.com/hVLgc4</a></p>
