You need to have appropriate permissions to write(upload) a file on the server.
Read this [^]on MSDN to understand what all permission you would need.

Do you have the sufficient permission to upload the file ? is there any domain user name password you have for the hosting side?

I have four individual checkboxes in my form called as General, Direct, Indirect and Private. The issue is that when private is checked all others should be disabled and unchecked if checked. I have the following code for that:
if (PrivateCheckBox.Checked)
{
GeneralCheckBox.Checked = false;
GeneralCheckBox.Enabled = false;
IndirectCheckBox.Checked = false;
IndirectCheckBox.Enabled = false;
DirectCheckBox.Checked = false;
DirectCheckBox.Enabled = false;
}
else
{
GeneralCheckBox.Checked = true;
GeneralCheckBox.Enabled = true;
IndirectCheckBox.Checked = true;
IndirectCheckBox.Enabled = true;
DirectCheckBox.Checked = true;
DirectCheckBox.Enabled = true;
}
This serves the purpose but simply increases coding lines which I don't want. I can use the ternary operator, but only one operation can do with that, either checked or enabled. Can anybody have any idea how to achieve this with minimum line of code? I am not able to think of any other option.
Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

GeneralCheckBox.Checked = GeneralCheckBox.Enabled = !PrivateCheckBox.Checked;<br />
IndirectCheckBox.Checked = IndirectCheckBox.Enabled = !PrivateCheckBox.Checked;<br />
DirectCheckBox.Checked = DirectCheckBox.Enabled = !PrivateCheckBox.Checked;
only two letters away from being an asset

Add the check boxes (except private check box ) to a checkbox group. and use this code
foreach (CheckBox ch in CheckBoxList1.Items)
{
if(private.checked)
{
ch.Checked = false;
ch.Enabled = false;
}
else
{
ch.Checked = true;
ch.Enabled = true;
}
}
If you want to do similar kind of operation to a group of items then this is the standard way of doing that. Hope this help

foreach (control ctrl in page)
{
if(ctrl is checkbox)
{
((checkbox)(ctrl)).enabled = false;
((checkbox)(ctrl)).checked = flase;
}
}
|
|

This will not work, as it is giving the error as " foreach cannot operate on variables of type System.Web.UI.Page because System.Web.UI.Page does not contain a public definition for 'GetEnumerator'"

Add this code in your aspx page.
<INPUT type="hidden" id="MyHiddenField" runat="server" value="http://tbn2.google.com/xy/ab.JPG">
<img runat="server" id="hiddenImg" alt="" />
and in code behind add this code
HtmlInputHidden hidden = (HtmlInputHidden)Page.FindControl
("MyHiddenField");
Img.Src = hidden.Value;
Hope this help.

Hello Friends,
I've two dropdownlist(ddlCountry,ddlState). Onchange event of CountryDropdown(ddlCountry) StateNames are displayed into StateName dropdown using javascript. And it's working fine but prooblem is if i print the value of selected StateName on a button click at code-behind i got an error <b>Object reference set to an instance of an object</b>. So can anybody let me know what should i do know
|
|
|
|
|
your question is clear... Plzzzz send the code upto which level you have tried and the line where u r getting that error...
|
|
|
|
|
This is my javascript function
function myFunc()
{
if(document.getElementById("ddlCountry").value=="India")
{
//Remove Existing Values
var e=document.getElementById("ddlState");
while(e.firstChild)
{
e.removeChild(e.firstChild);
}
var myArray=new Array(2);
myArray[0]="Delhi";
myArray[1]="Mumbai";
for(var i=0;i<myArray.length;i++)
{
//Option(Text,Value)
e.options[i]=new Option(myArray[i]);
}
}
else if(document.getElementById("ddlCountry").value=="America")
{
//Remove Existing Values
var e=document.getElementById("ddlState");
while(e.firstChild)
{
e.removeChild(e.firstChild);
}
var myArray=new Array(2);
myArray[0]="Washington";
myArray[1]="LA";
for(var i=0;i<myArray.length;i++)
{
//Option(Text,Value)
e.options[i]=new Option(myArray[i]);
}
}
}
This is my .aspx code
<asp:DropDownList ID="ddlCountry" runat="server" onchange="myFunc(this)">
<asp:ListItem Text="Select Country" Value="Select Country"></asp:ListItem>
<asp:ListItem Text="India" Value="India"></asp:ListItem>
<asp:ListItem Text="America" Value="America"></asp:ListItem>
</asp:DropDownList>
<asp:DropDownList ID="ddlState" runat="server">
</asp:DropDownList>
This is my Code-Behind(on button click event) code
string name = ddlCountry.SelectedItem.Text+","+ddlState.SelectedItem.Text;
Label1.Text = name.ToString();
And ddlState.SelectedItem.Text getting null that's why that's throwing error
|

i too got the same error from your code... The problem is due to postback. The ddlCountry value is maintained but ddlState value is not maintained. So, the error appears. Try to maintain the value for the ddlState too...

Save the state of drop down list get value from request.form or query string do not fill all entry every time because if you did so every time new values is filled and state can not be maintained you can try one more option before submitting the form save the value into hidden variable by using java script and then get values from request object not from drop down because it lost their value when it fill again

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER proc [dbo].[Usp_D_et_Login1234]
@name nvarchar(max),
@pwd nvarchar(100),
@type nvarchar(5)
as
begin
if @type='1'
begin
select DId,LoginName from dd_login where LoginName=@name and Password=@pwd
end
if @type='0'
begin
select RId,LoginName from dr_login where LoginName=@name and Password=@pwd

Is this stored procedure can be injected?
If yes tell me how ?

public int chkAdminFold;
private void Page_Load(object sender, System.EventArgs e)

try
{
BlackList = new string[]{"--", "/*", "*/", "@@", "function", "truncate", "procedure",

chkHome = Request.ServerVariables["URL"];
chkAdminFold = chkHome.ToLower().IndexOf("admin");
if(chkAdminFold!=1)
{
// Form
//for(int i=0; i<Request.Form.Count;i++)
//if(CheckStringForSQL(Request.Form[i].ToString()))
//Response.Write(chkHome);
//Response.Redirect(ErrorPage);
// Query String
for(int i=0; i<Request.QueryString.Count;i++)
if(CheckStringForSQL(Request.QueryString[i].ToString()))
Response.Redirect(ErrorPage);
// Session
for(int i=0; i<Session.Count;i++)
if(CheckStringForSQL(Session[i].ToString()))
Response.Redirect(ErrorPage);

catch(Exception ex)
{
Response.Write(ex.Message);
}
}
private bool CheckStringForSQL(string pStr)
{
if(pStr == string.Empty)
return false;
else if(pStr == "")
return false;
else if(pStr == null)
return false;
if (pStr.CompareTo("")==0)
return false;
string lstr = pStr.ToLower();
for(int ii=0;ii<BlackList.Length;ii++)
{
if(lstr.IndexOf(BlackList[ii])>=0)
return true;
}
return false;
}
