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,
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
|
|
|
|
|
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

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
Connection: close
Authorization: Basic dXNlcjpwYXNz
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"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:ns1="http://localhost:8080/Service.wsdl"
xmlns:ns2="http://tempuri.org/ns1.xsd"><SOAP-ENV:Body><ns2:GetDBOldestPendingRow><iMaxRows>100</iMaxRows></ns2:GetDBOldestPendingRow></SOAP-ENV:Body></SOAP-ENV:Envelope>
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.....

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!

Thank you d@nish for trying to help me,
finally I found the right solution, and I'm going to write it down for every one.
first we have to get the cells range (the code is written within a simple for loop):
object kui = Exl.Cells[i+1,4];
Microsoft.Office.Interop.Excel.Range mr = Exl.get_Range(kui, kui);
then write this lines of code:
mr.Cells.Worksheet.Shapes.Item(i + 1).IncrementLeft(7);
mr.Cells.Worksheet.Shapes.Item(i + 1).IncrementTop(23);
and to rotate the increment you just need to write the numbers within the brackets in negative like that
mr.Cells.Worksheet.Shapes.Item(i + 1).IncrementLeft(-7)

If it is a Windows based mobile, RAPI is what you need to use. Here[^] is a library which can help you.
Not sure about other mobiles though.

hi.., gayatri..,
well am dividing your question in two parts.., that is
1. reading phone related data from the phone (ex: SMS, Phone Book etc..)
2. Reading extranal device data from the phone(ex: The files which are stored in the extranal Flash(momery card))
for the 1st one .., u have to aware of the modem at commands of your Phone manufacturer , for example if u want to read sms from the phone: give the command as AT+CMGL="ALL"(to read all sms's) , AT+CMGR=1(read 1st sms). ( for more details, like reading Phone book , signal quality etc.. read Phone modem manufactures AT Commands Guide). Before this U must have the knowledge of Serial communication.
For Serial communication see: System.IO.Ports Class
for the 2nd one.., Every phone there are two flashs, one is internal flash, 2 nd one is external.., for the 1st one, U must have the Protocol for the communicate the internal flash.., second one u can directly read data from the drive which is detected in your pc.
Thanks
