This article was previously published under Q170609<br />

<div class="symptoms_section"><br />
<br />
== SYMPTOMS ==<br />
<br />
Issuing a PUTFILE command to Drive &quot;A&quot; without having a floppy disk in that drive causes an Invalid Page Fault in Visual FoxPro 5.0 and 5.0a.<br />
<br />
</div><br />
<div class="resolution_section"><br />
<br />
== RESOLUTION ==<br />
<br />
Do not specify a drive letter in the PUTFILE command and allow the drive to be selected from the SAVE AS dialog box.<br /><br />
<br /><br />
NOTE: This is not the best remedy for this problem but it does prevent the Invalid Page Fault and subsequent closing of Visual FoxPro. The Invalid Page Fault does not occur in Visual FoxPro 3.0b.<br /><br />
<br /><br />
A better alternative to receiving the Invalid Page Fault is to verify whether the floppy drive has a disk in it prior to issuing the PUTFILE command. The following code is a function to which you pass to drive letter that is checked. The function returns a True (.T.) if there is a disk in the drive and a False (.F.) if the drive is empty.<br />
<pre class="codesample"> **********************************************************<br />
* FUNCTION isdiskin<br />
**********************************************************<br />
*<br />
* Passed - drive root specification, such as &quot;A:\&quot;, &quot;B:\&quot;, etc<br />
* Returns - logical .T., .F. depending on whether drive exists<br />
*<br />
* Usage -<br />
* ? isdiskin(&quot;A:\&quot;)<br />
*<br />
* Any drive formatted with an MS operating system &gt; DOS 3.3 will<br />
* have a nonzero volume serial number. If the specified drive<br />
* doesn't exist, it will return a 0 volume serial number. So,<br />
* GetVolumeInformation() can function as a replacement<br />
* for the old IsDiskIn.Bin that used to ship with FoxPro for DOS.<br />
PARAMETERS m.rootpath<br />
<br />
DECLARE GetVolumeInformation IN win32api STRING, STRING @, ;<br />
INTEGER, INTEGER @, INTEGER @, INTEGER @, STRING @, INTEGER<br />
<br />
m.volname = SPACE(255)<br />
m.volnamelen = LEN(m.volname)<br />
m.volumeserialnumber = 0<br />
m.maxfilenamelen = 0<br />
m.filesystemflags = 0<br />
m.filesystemname = SPACE(255)<br />
m.fsnamelen = LEN(m.filesystemname)<br />
<br />
=GetVolumeInformation(m.rootpath, @m.volname, m.volnamelen, ;<br />
@m.volumeserialnumber, @m.maxfilenamelen, ;<br />
@m.filesystemflags, @m.filesystemname, m.fsnamelen)<br />
IF m.volumeserialnumber = 0<br />
RETURN .F.<br />
ELSE<br />
RETURN .T.<br />
ENDIF<br />
</pre><br />
Another resolution to the Invalid Page Fault problem is to issue a DISKSPACE(&quot;A&quot;). This command returns a -1 if there is no disk in Drive &quot;A&quot; and returns some number greater than -1 if there is a disk in Drive &quot;A.&quot;<br />
<br />
</div><br />
<div class="status_section"><br />
<br />
== STATUS ==<br />
<br />
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This has been corrected in Visual FoxPro 6.0.<br />
<br />
</div><br />
<div class="moreinformation_section"><br />
<br />
== MORE INFORMATION ==<br />
<br />
In Visual FoxPro 5.x, if the following code is issued and there is no floppy disk in the &quot;A&quot; drive, an Invalid Page Fault occurs and Visual FoxPro closes:<br />
<pre class="codesample"> ? PUTFILE(&quot;Label File&quot;,&quot;A:\test&quot;,&quot;dbf&quot;)<br />
</pre><br />
The following error message appears in Windows 95:<br />
<div class="errormessage"><br />
<br />
This program has performed an illegal operation and will be shut down.<br />
<br />
</div><br />
Clicking Details reveals the following message:<br />
<div class="errormessage"><br />
<br />
VFP caused an invalid page fault in module &lt;module name&gt; at &lt;memory address&gt;.<br />
<br />
</div><br />
In Windows NT 4.0, the following error appears:<br />
<div class="errormessage"><br />
<br />
An application error has occurred and an application error log is being generated.<br /><br />
VFP.exe<br /><br />
Exception: access violation &lt;error number&gt;, Address: &lt;memory address&gt;.<br />
<br />
</div><br />
The operating system then closes Visual FoxPro.<br /><br />
<br /><br />
If the PUTFILE function is issued without specifying a drive letter, the Invalid Page Fault does not occur. A &quot;SAVE AS&quot; dialog box appears and if the &quot;A&quot; drive is selected and does not contain a floppy disk, the following non-fatal error message is issued:<br />
<div class="errormessage"><br />
<br />
A:\ is not accessible. The device is not ready.<br />
