i dont know right but i think this way dont be bad:
u can open global.asax.cs
and in htis function write this form:
protected void Session_Start(Object sender, EventArgs e)
{
Session["strUserName"]="aaa";
}
that means you can control that amount of session dont be null.

ViewState Concept is based on Hidden Field Concept
The main Purpose of ViewState is To maintain Persistant values for controls under postback implementation
Global.asax is the file that is compiled first when u complie ur application
It will have Session Events and applciation Events
U can have atmost one Global.asax for a project
Response.Redirect redirects from Ur Form to specific Site/Form
It causes roundtrip.U can pass query strings using this
Server.Transfer simply transfers the form to server.Here the transferred Url will not be visible to the user
Response.Output.Write writes the output in a more formatted form

g = Graphics.FromImage(bmp)
g.TranslateTransform(pb.Width / 2, pb.Height / 2)
g.DrawEllipse(New Pen(color.MediumTurquoise, 1), 0, 0, 2, 2)
cntnr = g.BeginContainer(rect1, rect2, GraphicsUnit.Pixel)
g.TranslateTransform(20, 20)
g.Clear(BackColor)
g.DrawRectangle(New Pen(Color.FromArgb(255, 255, 255)), 0, 0, 100, 100)
g.EndContainer(cntnr)
g.DrawLine(New Pen(Color.Blue, 1), 0, 0, 200, 200)
I'm confused why I lost all my scratches before the "g.BeginContainer",if I use the g.clear in the container?

Hi,
Does IIS (Win XP version) support multithreading?
If so,how do we manage multithreading in IIS?

I want to stay with GridView (unless another view can easily for sorting and display in rows), but I want to make some rows bold depending on the contents of a field. I have an extra text field returned with my query that is null of "Bold" and I want the null rows to show normal and the bold rows to show as bold. Can this be done? How?
Thanks

To change the format of the gridview row, you can create a handler for the RowDataBound[^] event of the GridView control. In the handler, you can format the background color of the row based on data using the BackColor or the CssClass property of the GridViewRow instance (e.Row).

VS2k5
Win2k3
IIS6
.NET 2.0
In my ASP.NET 2.0 app I create and open an SQL connection in the page's constructor and call Dispose() in the destructor. The SQLConnection
object is a class member of the page. This page makes heavy use of the SQLConnection object so I felt opening and closing in the constructor/destructor respectively was good design. I know this doesn't take full advantage of connection pooling. Any design input would be very much appreciated.
Here's the destructor code:
/// Destructor
~Officer()
{
if( m_objConn != null )
m_objConn.Dispose(); // <-- Exception occurrs here.
}
/// End Destructor
When running this particular page through some testing I get the following exception in the destructor at the "m_objConn.Dispose();" line:
System.InvalidOperationException was unhandled
Message="Internal .Net Framework Data Provider error 1."
Source="System.Data"
StackTrace:
at System.Data.ProviderBase.DbConnectionInternal.PrePush(Object expectedOwner)
at System.Data.ProviderBase.DbConnectionPool.PutObject(DbConnectionInternal obj, Object owningObject)
at System.Data.ProviderBase.DbConnectionInternal.CloseConnection(DbConnection owningObject, DbConnectionFactory connectionFactory)
at System.Data.SqlClient.SqlConnection.Close()
at System.Data.SqlClient.SqlConnection.Dispose(Boolean disposing)
at System.ComponentModel.Component.Dispose()
at Officer.Finalize() in c:\sys\projects\AddOfficer.aspx.cs:line 46
1) Is this design good/bad?
1) Is this a bug?
2) Do I need a try/catch in a destructor? Is it good programming practice?
3) Why is this happening?
4) What is the meaning of life?
Any help is appreciated. TIA

Hi, I'm currently writing an application that has a collection of complaints (in an microsoft sql server database).
Now they want us to make it possible to upload files (mostly doc's and mails) and bind them to a complaint, so that later when another employee is browsing throught the complaints he can download/open files that belong to a certain complaint.
security is not an issue because it is an intranet application.
What we also thought of, was to store the files in the database (we're talking about a small app with few data) but I have no idea if that compromises performance or not.
As you can see we're quite new to all this, so any help is much appreciated, thx in advance.

You could, I suppose, handle the OnDayRender event and clear contents of cells you didn't want displayed. Something like this:
<%@ Page Language="C#" %>
<script runat="server">
void Page_Load(object o, EventArgs e)
{
}
void CustomDayRender(object o , DayRenderEventArgs e)
{
if (e.Day.Date >= System.DateTime.Today.AddDays(-3)
&& e.Day.Date <= System.DateTime.Today.AddDays(4))
{
e.Cell.BackColor = System.Drawing.Color.Honeydew;
}
else
{
e.Cell.Controls.Clear();
}
}
</script>
<html>
<head>
<title></title>
</head>
<body>
<form runat="server">
<asp:Calendar id="Calendar1" runat="server"
OnDayRender="CustomDayRender"
/>
</form>
</body>
</html>

HI,
I have read some papers and they tell that WSE 2.0 with WS-attachments does not encrypt the attachments ( they recommend using secure protocol like SSL to secure attachments). Now, WSE 3.0 replace WS-attachments with MTOM, I have found that MTOM is used for transmit large binary data, but I don't know whether we can encrypt it directly with WSE 3.0 or not.
If you have answer, plz tell me.
Thanks,
Hung

Is there any way to Hide "Create User" buttom?? I want to Hide this button when a value from a drop down is selected. That time i want to display Edit User Button!!
Thanks in Advance.
|

you can do it in two ways:
1. (preferably this) on client using javascript: add onchange attribute to dropdownlist and call a javascript function showHideButton like..
add attribute in code behind:
dropdownlist.attributes.add("onchange", "javascript:showHideButton(this.selectedIndex);")
javascript:
function showHideButton(index){
if(index > 0){ // i am assuming you have --NEW-- at zero index
document.getElementById("createuser").style.visibility = "hidden";
document.getElementById("createuser").style.display = "none";
document.getElementById("updateuser").style.visibility = "visible";
document.getElementById("updateuser").style.display = "block";
}
else {
document.getElementById("createuser").style.visibility = "visible";
document.getElementById("createuser").style.display = "block";
document.getElementById("updateuser").style.visibility = "hidden";
document.getElementById("updateuser").style.display = "none";
}
}
in the above case you have to create two buttons and hide one on loading of the page..
i suggest you to create only one button and change its text to Create User ot Update user on changing the value of list... on click event of button in code behind check its text and act accordingly..
2. on server side:
set autopostback=true for the dropdownlist.
then write a onselectedindexchanged handler in code behind and set visible=true or false for each button depending on selected index of the dropdownlist..

I want to create an Access Database for my website...essentially like a guestbook example but with more data. Do I need Visual Studio to accomplish this or can I simply create script and ftp it to my server? BTW, I do have MX Studio...so I have Flash and Dream Weaver. Sorry about stupid question but I am new to this. Thanks,

You don't need Visual Studio, it's possible to write all code using any generic editor like Notepad, but Visual Studio contains a lot of stuff that makes it a lot easier.
You can download Visual Web Developer Express Edition[^] for free from Microsoft.
