Why do you open it as an image? Then you have to recompress it to send it to the client. Just send the file as binary data:
Response.ContentType = "image/tiff";<br />
Response.WriteFile("c:\data\pr0n.tiff");
(Verify that the mime type is correct, I only made a guess...)

I have tried that, but I get exactly the same message
It seems to be a common problem?
|
|
|
|
|
Where does the error message come from? Does it occur when downloading the image or viewing it? What program is used to view the image? Can the image be viewed on the client machine if it hasn't gone through the process of downloading it, but copying it directly?

sorry for late reply,
I get the message after downloading when trying to open the file,andwhen trying to open it directly,strangelyit worked once earlier but then not again.
If it is copied directlythe image seems to be opening, but that won'tbe possible on the finished system.
The default viewer will be MS Image and Fax viewer

|
|
|
If it works when copied directly, but not when downloaded, that suggests that the file is not sent properly.
What does the code look like that sends the file? What content type are you using?

Hai to all,
I have a small doubt regarding asp.net class files.
What's the difference between class file and module file.
In asp.net we can use both of them module.vb of class.vb.
Exactly where they will differ and when we have to use them in a project.
which is the best option for,declaration of dataconnection??
Either in web.config or module.vb ???
Even though it is silly question, please can any one respond to this.
Thanks in advance

Scope. The scope of standard modules is the entire app life.
Class modules can be instantiated and destroyed anytime. I
put my connection strings and all related (encrypted) in
the stan. module..you can do either.

Hi,
Assuming that you are using ASP.NET 2.0 framework, there's a nice Menu control provided in ASP.NET 2.0 which you can easily use for the same.
Given below is the strategy and the code for the same.
Table Design -
CREATE TABLE [dbo].[Menu_Master] (
[Menu_ID] [int] NOT NULL ,
[Menu_Name] [varchar] (200) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,
[Menu_Desc] [varchar] (300) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Parent] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Sequence] [int] NOT NULL ,
[OnClickAction] [varchar] (500) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,
[Roles] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[Menu_Master] WITH NOCHECK ADD
CONSTRAINT [PK_Menu_Master] PRIMARY KEY CLUSTERED
(
[Menu_ID]
) ON [PRIMARY]
GO
__________________________________________________________________________
Menu populating Method -
private void PopulateMenu(SqlDataReader dtMenuData, ref Menu popdownMenu)
{
Hashtable RootNodeReferrer = new Hashtable( );
SqlDataReader MenuData;
int Counter = 0;
int Level = 0;
int Id = 0;
MenuItem PopDownMnuItem;
MenuData = dtMenuData;
try
{
while (MenuData.Read( ))
{
Id = Convert.ToInt32(MenuData["Menu_ID"]);
PopDownMnuItem = new MenuItem( );
if (Level == Convert.ToInt32(MenuData["Parent"]))
{
PopDownMnuItem.Text = MenuData["Menu_Name"].ToString( );
PopDownMnuItem.NavigateUrl = MenuData["OnClickAction"].ToString( );
PopDownMnuItem.Value = Counter.ToString( );
PopDownMnuItem.ToolTip = MenuData["Menu_Desc"].ToString( );
if (MenuData["OnClickAction"].ToString( ).Trim( ) != "")
{
PopDownMnuItem.Selectable = true;
}
else
{
PopDownMnuItem.Selectable = false;
}
if (Counter != 0)
{
MenuItem SepItem = new MenuItem("", "", "~\\Images\\VerMenuSep.jpg", "");
popdownMenu.Items.Add(SepItem);
}
popdownMenu.Items.Add(PopDownMnuItem);
RootNodeReferrer.Add(Id, PopDownMnuItem.ValuePath);
}
else
{
MenuItem ParentItem = popdownMenu.FindItem(RootNodeReferrer[Convert.ToInt32(MenuData["Parent"])].ToString( ));
if (ParentItem != null)
{
PopDownMnuItem.Text = MenuData["Menu_Name"].ToString( );
PopDownMnuItem.NavigateUrl = MenuData["OnClickAction"].ToString( );
PopDownMnuItem.Value = Counter.ToString( );
PopDownMnuItem.ToolTip = MenuData["Menu_Desc"].ToString( );
if (MenuData["OnClickAction"].ToString( ).Trim( ) != "")
{
PopDownMnuItem.Selectable = true;
}
else
{
PopDownMnuItem.Selectable = false;
}
ParentItem.ChildItems.Add(PopDownMnuItem);
RootNodeReferrer.Add(Id, PopDownMnuItem.ValuePath);
}
}
Counter++;
}
}
catch (Exception ex)
{
throw ex;
}
finally
{
MenuData = null;
RootNodeReferrer = null;
PopDownMnuItem = null;
}
}
This method will populate the menu control with data fetched from the database and iterate through all the rows to create the required structure.
The important point to remember here is the way the actual data has to be populated in database. There are 3 main columns - Menu_Id, ParentId and Sequence. The importance is that Menu id will be a unique id, parent Id will give the id of menu level which acts as its parent and sequence will be the sequence in which a particular structure is created.
For eg - If we want a structure like
1 / 2,3
2 / 4,5,6
the Menu id will be
1 1 1 0 0(follow the above column structure)
2 2 2 1 1
3 3 3 1 2
4 4 4 2 1
5 5 5 2 2
6 6 6 2 3
I hope u got this point.. Its difficult to describe it visually.. still I have tried to do so..
This should solve all ur problems.
Thanks and best regards

Hi friends.
I am cearting my website using Asp.net ( code C# ) and sqlserver2000... I need "search" in a webform.
for example, when the user types " demo " in the textbox of the search page, then it should appear all the things in all pages of the website,which is correlate with the word "demo".
Just like the search in codeproject.
how can I do it ?
I just know about searching with a specific field,like user name,age,... but I dont have any idea about a word searching ...
is there any articles which can help me?
Or can anyone help me to write ...?
thanks alot.

You want to use a 'like' query on your database which allows you to search through string which 'looks like' your string... the syntax is easy
select field1, field2 from table where field1 like '%demo%'
this returns all rows where field1 contains the string 'demo'. However, you may consider using and/or functionality in your websearch, for example when a visitor enters demo+csharp in the textbox. Your query should look like this
select field1, field2 from table where field1 like '%demo%' and field1 like '%csharp%'
If the user enters 'demo csharp' as search text, you want
select field1, field2 from table where field1 like '%demo%' or field1 like '%csharp%'
This makes searching complicated. Afterwards you want to sort the result set having the most relevant match on top. For example you can count the number of matches for each result in the result set and order the result set depending on that number of matches having the most matches on top.
You can make search functionality as easy or as complicated as you want...

hai,
i am working on asp.net1.1(vb.net). when i am accessing the application from server ,getting the following error
where i have to correct this.
please provide some solutions.
thanks and regards,
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customerrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customerrors> tag should then have its "mode" attribute set to "Off".
<configuration>
<system.web>
<customerrors mode="Off">
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customerrors> configuration tag to point to a custom error page URL.
<configuration>
<system.web>
<customerrors mode="RemoteOnly" defaultredirect="mycustompage.htm">

string m_path;
m_path = Server.MapPath(".").ToString();
FileInfoCollection objFiles = new FileInfoCollection();
DirectoryInfo objSecondDir = new DirectoryInfo(m_path + "\\"
+ "PoliciesProcedures");
objFiles.AddRange(objSecondDir.GetFiles());
int totalfiles = objFiles.Count;
GridPolicyUpload.DataSource = objFiles;
GridPolicyUpload.DataBind();
now for this DirectoryInfo i need to make a datatable and insert in it. Since i had to do sorting in it .
i tried with this
DataColumn myDataColumn;
myDataColumn = new DataColumn();
myDataColumn.DataType = Type.GetType("System.String");
myDataColumn.ColumnName = "Name";
myDataTable.Columns.Add(myDataColumn);
myDataTable.Rows.Add(objFiles.T
but i could'nt ????????
can anyone help me out ???????
thanks in advance

Try this......
DataColumn myDataColumn;
myDataColumn = new DataColumn();
myDataColumn.DataType = Type.GetType("System.String");
myDataColumn.ColumnName = "Name";
myDataTable.Columns.Add(myDataColumn);
DataRow dr=myDataTable.NewRow();
dr["Name"] = objFiles.T
myDataTable.Rows.Add(dr)
