Hi all,
I have a problem.
In my web application I have to load controls dynamically. I would like to access some properties of these controls. Assuming that the control that I have to load is called "MyControl.ascx". I have to write:
MyControl oNewControl = (MyControl)LoadControl("MyControl.ascx");
The problem is that my VS2005 don't find the MyControl name and give me a compile error.
I don't understand how to import the namespace there the MyControl definition is placed.
What I'm wronging???
can you help me?
Regards
Federico

Try compiling the user control code behind. Drop the DLL into the application bin and on the page, just import the namespace that your user control resides.
Then, this should work.
oNewControl = LoadControl("MyControl.ascx");

MyControl.ascs should be under the same directory where the page that you wrote this code is located.

What do you mean? What is wrong with the results you are getting?
You need to be more specific about the problems you are experiencing, otherwise no one will know how to help you.

how to convert string into System.Web.UI.DropDownList
I am having 31 dropopdownlists which is supposed to have same values from the data base. How to create an array of dropdownlists to populate all the dropdownlists in a single function.
while trying this i made the following code which shows the error that
"converting string into System.Web.UI.DropDownList not possible"
private void pop_list_shiifts()
{
for(int i=1;i<=31;i++)
{
string Dd_day_shift_i;
DropDownList strr=Dd_day_shift_i;
strr.Items.Add("-Select-");
SqlDataAdapter da = new SqlDataAdapte("sqlstring",con);
DataSet Obj_dse = new DataSet();
da.Fill(Obj_dse);
strr.DataTextField=Obj_dse.Tables[0].Columns["day"].ToString();
strr.DataSource=Obj_dse;
strr.DataBind();
}
}
|
|
|
|

Take a look here:
string Dd_day_shift_i;
DropDownList strr=Dd_day_shift_i;
Dd_day_shift_i is a STRING and you are tring to assign it to a DropDownList object (second row of code).
Bye

what u r intending to say?conversion is not possible or what?
if there any solution ,let me know..
|
|
|
|

In your code you have this string referece
<br />
string Dd_day_shift_i;<br />
In this line of code
<br />
DropDownList strr=Dd_day_shift_i; <br />
you are tring to assign a string reference to a DropDownList reference and it's not possible.
Which is the target of this code? Do you want to add some items in the DropDownList?
Regards
Federico

private void pop_shift(DropDownList ddl)
{
ddl.Items.Add("-Select-");
SqlDataAdapter da = new SqlDataAdapter("select shift_name from shift_add",con);
DataSet Obj_dse = new DataSet();
da.Fill(Obj_dse);
ddl.DataTextField=Obj_dse.Tables[0].Columns["shift_name"].ToString();
ddl.DataSource=Obj_dse;
ddl.DataBind();
}

Can you put your dropdown lists in a repeater control? Only need to set up the binding in one place then.

Hi all,
I have a code like this.If any error occurs I want to retrive the varriable which generated the error.How can I ?
Try
'Error if the user inputs some string
Dim strCode As Integer= Request.QueryString("Code")
Catch ex As Exception
Response.Write(?)
End Try
Thanks
Dana

Try
'Error if the user inputs some string
Dim strCode As Integer= Request.QueryString("Code")
Catch ex As Exception
Response.Write(Request.QueryString("Code"))
End Try
Something like that?
|
|
|
|
|
Thanks for the reply Paddy Boyd,
Can I able to write the varriable name which produced the error.Like
Response.Write(Request.QueryString("strCode"))
|
|
|
|
|
Why would you need to do that? You can print the error message and the stack trace - these will contain that information, but i don't think you really want to do that.

Suppose if am going to test the values for more that one column then i have to write this like one..
Try
'Error if the user inputs some string
Dim strCode As Integer= Request.QueryString("Code")
Catch ex As Exception
Response.Write("Invalid code")
End Try
Try
'Error if the user inputs some string
Dim strCode As Integer= Request.QueryString("Age")
Catch ex As Exception
Response.Write("Invalid Age")
End Try
Like that...
But I want to do some thing like
Try
'Error if the user inputs some string
Dim strCode As Integer= Request.QueryString("Code")
Dim strCode As Integer= Request.QueryString("Age")
Catch ex As Exception
Dim strDescription as string=String.Empty
'Check for the value generted the eror
'and assign description
Response.Write("Invalid" & strDescription )
End Try
Thank
Dana

I can set up a website with some folders requiring that users log in before being able to access the aspx pages therein using forms.authentication, and configuring web.config appropriately - all fine and dandy.
So if, say, a protected folder is "members" and someone tries to access members/index.aspx they are redirected to a login page first. Great - but if there is a pdf in that folder, say members.pdf then ANYONE can still browse directly to members/members.pdf WITHOUT being logged in.
How do I set about protecting .pdf, .doc, jpg etc files from unauthorised access in this way? Just a pointer will do.... thanks

You can write the handler and allow .pdf/.doc/.jpg etc access only through application and stop them when trying to access through browser directly.

hmm... tried that, word for word, and an even simpler "hello world" type example I found elsewhere (though it was the almost identical code) - and while it compiles fine, when I try to browse to an aspx file in the app I get the error:
"Could not load type [class name] from assembly [assembly name]"
(If I browse to a jpg - one of the filetypes I'm trying to protect - it is shown as normal.)
I have tried googling this error, but have found nothing useful - just a reference to it possibly being to do with the GAC, but no help...
... I don't suppose you've got any ideas...?
cheers
Fred
