I need to convert Byte value into integer.

From what you have described it would seem you want to convert a byte to its hex value not an int (here[^])...

and a byte value of 7 would not equal 10000000 it would be 00000111 which is 07 surprisingly Wink | ;)

simple - use <<

private int ToBin(int bitNo)
   {
   if (bitNo >= 32)
      {
      throw new Exception("Too big for int32");
      }
   return 1 << bitNo;

damn, accidentally deleted my initial message...

Thanks. Do you have any idea where I can find older interops? Such as for office 2000 (i.e. version 9). They don't seem to be available anywhere - I guess there is a reason for that though.

As far as I am aware there aren't any. You have to make your own. PIA's are just imported COM type libraries with nice .net friendly wrappers around the ugly interop code.

There's some discussion on it here[^]. Also, check the links at the bottom of the page for some more discussion.

How to use session ??

lsh486love11-May-09 21:23

11-May-09 21:23

I'm making a login page with ASP.NET with C#.

and I know that it needs to use Session for saving information of loggined user.

so I used Session like this on "login.aspx.cs" with Login View Control.

[login.aspx.cs]

// Database query.

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["Join"].ConnectionString);
SqlCommand cmd = new SqlCommand("SELECT * From User WHERE id = @ID", con);
cmd.Parameters.AddWithValue("@ID", ((TextBox)LoginView1.FindControl("TextBox1")).Text);

string name = rd["name"].ToString();
string pw = rd["password"].ToString();
string pw1 = ((TextBox)LoginView1.FindControl("TextBox2")).Text;
string id = rd["id"].ToString();

// Save to Session variables. There are a lot of components about Session. Keys, Item, Add,
//and so on..

Session["memberid"] = id;
Session["membername"] = name;

if ((string.Equals(pw, pw1)) == true)
{
FormsAuthentication.RedirectFromLoginPage(name, false);
}

....
And I made codes like this whether lggined user is same with Writer on board or not.

[Board.aspx]

public static bool IsWriter(string pdsId, string Writer)
{

string sql = "Select id From t_Pds Where boardId = @boardId And writer = @writer";
SqlCommand cmd = new SqlCommand(sql, DbConn.GetConn());

cmd.Parameters.AddWithValue("@boardId", pdsId);
cmd.Parameters.AddWithValue("@writer", Writer);
cmd.Connection.Open();
string result = (string)cmd.ExecuteScalar(); // result = ID of writer value.
cmd.Connection.Close();

// I can't use Session. When I use "Session", there are no components of Session.
// There are only two values of Session. ( SessionPageStatePersister , SessionParameter)

if (Session["memberid"] == result) //ERROR.
{
return true;
}
else
return false;

}

Hi guys

I have the code to get the directory list of the xml files in an folder but the problem is that i want to get the files in the creation date order. in other words each file has got an date it was created.

now i want to load all these xml files into an list array and in the creation date order.

is this possible? Confused | :confused:

my code sofar:

private String[] GetDirectory(String XmlFilePath)
{
    List<String> strList = new List<string>();

    FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(XmlFilePath);
    request.Credentials = new NetworkCredential(Username, Password);
    request.Method = WebRequestMethods.Ftp.ListDirectory;
    StreamReader sr = new StreamReader(request.GetResponse().GetResponseStream());

    while (!(sr.EndOfStream))
    {
        strList.Add(sr.ReadLine());
    }

    sr.Close();
    sr = null;

    return strList.ToArray();
}

i would use something like

string fileName = "/path/to/your/file";
DateTime dt = File.GetCreationTime(fileName);

and then work with the returned date depending on how you wanted to order it.

have a look at this for some pointers

Hi,

Anybody knows how to convert postscript file of ghostscript printer to dictionary using itextsharp or programatically by any other tool I had tried this command : -

gswin32c -q -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=test.pdf -fc:\\output.ps

But the pdf generated gives the error %%EOF not found

Re: convert postscript to pdf

Replace the -fc:\\output.ps with just the name of one or more .ps files.
Probably need to add -dBATCH as well, so its more like:

gswin32c -q -dNOPAUSE -sDEVICE=pdfwrite -dBATCH -sOutputFile=test.pdf c:\output.ps

Adding Authentication in C# client for gSOAP C++ webservices........

King Julien11-May-09 19:46

11-May-09 19:46

Hi CP gurus,

I have a gSoap Web Service written using C++, it uses SOAP username and
password authentication.

I also have a C# client consuming the web service, all this was working
fine until I added the authentication on the server, now I can not get the
client to authenticate web service methods. Can someone tell me how to add authentication info
to the SOAP message posted from the C# SOAP client.

It may look something like this...

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:ns1="http://localhost:80/Service.wsdl"
xmlns:ns2="http://tempuri.org/ns1.xsd"><SOAP-ENV:Body><ns2:getBatteryLevel></ns2:getBatteryLevel></SOAP-ENV:Body></SOAP-ENV:Envelope>POST
/ HTTP/1.1
Host: localhost:8080
User-Agent: gSOAP/2.7
Content-Type: text/xml; charset=utf-8
Content-Length: 489

SOAPAction: ""

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

No how to add the blocked Authentication line in the SOAP message.....???

Searched Google... but no clue is left....

Thank in advance for your help.....

Have a Happy Coding.....

DataGridView CellPainting (some cells only)

John Jak11-May-09 19:36

John Jak

11-May-09 19:36

I have noticed that updating a DGV (only a couple of cells), still has the application repainting the whole grid when an Update occurs! I have an application with up to 6 DataGrids with 5 columns and up to 40 rows. As I step through my loaded database, I see results changing in real time on the DataGrids but it is very slow as it sweeps across the screen. Flicker is certainly noticeable on cell values that have not changed.

I don't see the need to repaint up to 1200 cells when only a few of them have actually changed (value & BackColor).
Even on a blank grid, I have stepped through the CellPainting Event when only the selected cell has changed yet the whole grid is still repainted.

When I take care of the CellPainting myself, only the cells I want to update are modified some flicker is still visible but the performance is vastly improved. However, the other cells are messed up from other windows when they get on top or when my window is resized.
I have noticed the ClipBounds property from the DataGridViewCellPaintingEventArgs informs you of the area that needs to be painted.

Is there something I am missing about the DataGridView CellPainting? Any help much appreciated!
