Try FileOpStruct.fFlags = 20;<br />
This means the FOF_SILENT flag is added (Do not display a progress dialog box)

Hi &nbsp;nonubik,<br />
<br />
So it means that the error will happen but it just wont be displayed right??<br />
<br />
If it is so, is there a way to eliminate the error?<br />
<br />

I think so, haven't tested yet.<br />
<br />
&gt;If it is so, is there a way to eliminate the error?<br />
I think the error comes form the line <br />
&gt;totalPathToNetHood=&quot;C:\Do<wbr />cuments and Settings\suraj_guptha\NetH<wbr />ood&quot;<br />
Try replacing it with:<br />
<br />
&gt;totalPathToNetHood=@&quot;C:\D<wbr />ocuments and Settings\suraj_guptha\NetH<wbr />ood&quot;<br />
or<br />
&gt;totalPathToNetHood=&quot;C:\\D<wbr />ocuments and Settings\\suraj_guptha\\Ne<wbr />tHood&quot;<br />
<br />
<br />

</div>


<div>
I will try it. Meanwhile i just want to let you know that it works in a few machines and not in others
</div>


<div>
This is the code i am using<br />
<br />
string pathToNetHoodPart1 = Environment.GetFolderPath(<wbr />Environmen<wbr />t.SpecialF<wbr />older.Pers<wbr />onal);<br />
pathToNetHoodPart1 = pathToNetHoodPart1.Substri<wbr />ng(0,pathT<wbr />oNetHoodPa<wbr />rt1.LastIn<wbr />dexOf(&quot;\\&quot;<wbr />));<br />
string totalPathToNetHood = pathToNetHoodPart1 + &quot;\\NetHood\\*.*&quot;; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
<br />
SHFILEOPSTRUCT FileOpStruct = new SHFILEOPSTRUCT();<br />
<br />
FileOpStruct.wFunc = 3;<br />
FileOpStruct.fFlags = 16;<br />
FileOpStruct.pFrom = Marshal.StringToHGlobalUni<wbr />(totalPath<wbr />ToNetHood.<wbr />Replace(&quot;@<wbr />&quot;,&quot;&quot;).Repl<wbr />ace(&quot;\&quot;&quot;,&quot;<wbr />&quot;));<br />
<br />
Int32 a =SHFileOperation(ref FileOpStruct);<br />
<br />
When i debug this and paste the code from totalPathToNetHood into Run it opens the Nethood Folder <br />
But then SHFileOperaion is performed it throws an error<br />
<br />
Can u help?<br />

</div>


<div>
pFrom should have two NULL characters in the end.

Hi AlexFM,<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; So what should i add to totalPathToNetHood ?? Can u put the statement down from my code please?
</div>


<div>
<a href="http://www.pinvoke.net/default.aspx/shell32.SHFileOperation" rel="ugc">http://www.pinvoke.net/default.aspx/shell32.SHFileOperation</a><br />
<br />
See this code fragment:<br />
<br />
this._ShFile.pFrom = value + '\0' + '\0';<br />
<br />
I didn't test this code. If it will not work, I have my own function which makes pFrom buffer setting two NULLs in the end using Marshal class. I can post it some time later, I need to find it first.
</div>


<div>
It works like COOL<br />
Hey whats the significance of adding the NULL characters?
</div>


<div>
From my first post:<br />
<br />
MSDN topic SHFILEOPSTRUCT<br />
<br />
pFrom<br />
Address of a buffer to specify one or more source file names. Although this member is declared as a null-terminated string, it is used as a buffer to hold multiple file names. Each file name must be terminated by a single NULL character. An additional NULL character must be appended to the end of the final name to indicate the end of pFrom.<br />

I understand your previous post only now. How stupid of me :-)

I have a small problem with running the script for deleting the files in nethood folder. When i run the actual command it throws an error like <br />

I happens only on select machines.<br />

This happens when i call Int32 a =SHFileOperation(ref FileOpStruct);<br />

It is not an exception. It just displays the messagebox<br />
