Hello Amirreza_nl,
I wrote the code that was alluded to earlier in this thread (from CodeGator.com). You are correct that your code is similar to mine, however I am calling a slightly different method to get the path from the PIDL. In my case I am using the SHGetPathFromIDList function. Also, my code doesn't convert from the InPtr to a ITEMIDLIST structure. I am able to deal with PIDL's as IntPtr objects instead of converting them to ITEMIDLIST structures. (See my code here)
You don't say which call is failing in your code, is it SHGetSpecialFolderLocation or SHGetFileInfo?
My suggestion would be to try omiting the conversion of the PIDL to a struct if possible.
I hope I have helped,
Martin

Hi,
first of all, thanks for ur reply. I think SHGetFileInfo doesn't work well. because the first call's return value is ok. but SHGetFileInfo's return value sometimes is not ok. I run the code 2 or 3 times then it works well and show control panel's (or something else) attributes correctly! I don't know why!
SHGetPathFromIDList doesn't work at all with something like control panel (I think). we can use it when pidl is controled by file system(file or folder that is stored physically in a hard disk). so I can not use it for my app.
typedef struct _SHITEMID {<br />
USHORT cb;<br />
BYTE abID[1];<br />
} SHITEMID;
I wrote this in C#:
[StructLayout(LayoutKind.Sequential, Pack = 1)]<br />
public struct SHITEMID<br />
{<br />
public UInt16 cb;<br />
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 1)]public SByte[] abID;<br />
}
then
typedef struct _ITEMIDLIST {<br />
SHITEMID mkid;<br />
} ITEMIDLIST;
in C#:
[StructLayout(LayoutKind.Sequential, Pack = 1)]<br />
public struct ITEMIDLIST<br />
{<br />
public SHITEMID mkid;<br />
}

oh, I think I find the bug in my code!
I write:
[StructLayout(LayoutKind.Sequential, Pack = 1)]
but I must write:
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode, Pack = 1)]
instead.
I use unicode charset for my all methode definitions.
But I wonder why this makes a problem! we have two types of pidl!? on for ansi one for unicode!? why? in pidl address we have string!??

 Can someone please help me to open a file in the application using openFileDialog. I have a button "Open File" > which then opens an openFileDialog window, I then select the file and click Open, but it does not want to open. I do get the path and everything, but it does not want to open. Maybe I am using the wrong code. Here is a snippet of my code:
//Opens the file and populates the datagrid
private void btnOpenFile_Click(object sender, EventArgs e)
{
ofdExcelDoc.Filter = "xls files (*.xls)|*.xls|All files (*.*)|*.*";
if (ofdExcelDoc.ShowDialog() == DialogResult.OK)
{
ofdExcelDoc.OpenFile();
try
{
// Attempt to open the file and output its contents to a text box
Stream stream;
if ((stream = ofdExcelDoc.OpenFile()) != null)
{
StreamReader reader = new StreamReader(stream);
//dgFileInfo.DataSource = reader.ReadToEnd();
txtOutput.Text = reader.ReadToEnd();
stream.Close();
}
}
catch (Exception ex)
{
MessageBox.Show("There was an Error: " + ex.Message);
}
}
}
}

i still haven't understood xD, but i got it work,
it often occurs when TabAllignment changed,
try some steps,
1. Extact DGV from TC
2. Add new TC or TabPage
3. insert DGV in it
i hope it will work...
