Hi everebody,
After we applied the security update that is described in security bulletin MS07-040 - our ASP.NET 2.0 application started showing garbage data.
I read this http://support.microsoft.com/kb/940521/en-us[^] and suspecting that this is happening beacuse of this.
If we refresh the page then the garbage characters are removed.
Please help if you could suggest anything.
Thanks much.
Regards

Hi, I am still a newbie in ASP.net development,
I try to learn about nested master page, and I got this problem
Cannot find ContentPlaceHolder 'ContentPlaceHolderUser' in the master page '/OnlinePrayer/MasterPage/AdminUser.master'
I have done some research in internet, but until now, I have not got the right solutions.
basically, in my website, there are 2 master page : AdminUser.master and User.master
and AdminUser is child of User,
In User.Master , I've got this following code
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="User.master.cs" Inherits="MasterPage_User" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>UserPage</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:contentplaceholder id="ContentPlaceHolderUser" runat="server">
</asp:contentplaceholder>
</div>
</form>
</body>
</html>
and in AdminUser.master, i've got this code
<%@ Master Language="C#" MasterPageFile="~/MasterPage/User.master" AutoEventWireup="true" CodeFile="AdminUser.master.cs" Inherits="MasterPage_AdminUser" %>
<asp:Content ID= "SubContent1" contentplaceholderid="ContentPlaceHolderUser" runat="server">
</asp:Content>
I thought that I had define ContentPlaceHolderUser in User.Master, but I dunno why I still got this error? in Admin.Master
I would be grateful if you could give me feedbacks about my problems,
thanks

<title>Title
Some content in main master page
<asp:contentplaceholder id="ContentPlaceHolder1" xmlns:asp="#unknown">
runat="server">
Child master page will be placed here...
2.AdminUser.Master as follows(child master page for User as you said and here the Master page file is User.Master).
<asp:content id="Content1" runat="server" xmlns:asp="#unknown">
ContentPlaceHolderID="ContentPlaceHolder1">
This is child master page
| <asp:contentplaceholder id="ContentPlaceHolder1">
runat="server" EnableViewState="true">
Contents of pages...
Content in Child master page.
<asp:contentplaceholder id="ContentPlaceHolder2">
runat="server" EnableViewState="true">
Contents of pages.
|
3.Default.aspx page which uses the master page.(Master Page file is AdminUser.Master)
<asp:content id="Content1" xmlns:asp="#unknown">

I am trying to find a way to display the contents of multiline textbox on a print preview page to display and print the entire contents of what the user has typed in. Once the user types in data in the multiline textbox, the data is stored in a SQL database and then retrieved to be displayed on a print preview page to be printed? Any ideas? Sorry if the question is a little easy for some of you but I am a newbie to C# and .Net prgramming. Thanks is advance.

I can't figure why my images are not showing up on my web form - instead, there is that little icon indicating the image is there (otherwise, it would be a red cross).
I vaguely remember it happened to me a while ago while working with images - but don't know what it was.
Any idea? thanks.
|
|
|
|
|
Is that image really exist? Is that specified path correct?
|
|
|
|
|
Can you post the code that you have written and the path of the image

I think the problem is with image path. Run you web site, Right Click on Red Cross Icon, Click Properties. Or check the same from View Source. Now Compare the path of original source and the current source.

Hi all,
I am facing a strange problem regarding session variables. I developed a website where a kept the login information in Session variables. It worked fine but now Session is not maintained i have checked after response.Redirect the session is lost and the value is null on the redirected page. I have searched a lot and tried many solutions but useless. I have only one session variable which is used to store the user name to display it on all pages and allowing some login based functionality.
Please help me in this issue.
Looking forward to hear a solution from codeproject.
Thank You

What is the SessionState Mode[^] in your web.config? Is it set to off?
Be careful, there is no Undo Button(Ctrl+Z) in life.

Dear Sir,
I am using
sessionstate mode="InProc" cookieless="false" timeout="40"
Every thing was working fine a week ago.
Thank You

I know it's pretty basic.
I have some image controls on a page.
User will upload the images and the images will show up in the image controls as they are uploaded (there is a max number they can upload).
I was trying to access them to see if imageurl is empty - so I can take the first control to put the image, then the second one and so on.
But it's not working. Here's what I am trying:
foreach (System.Web.UI.WebControls.WebControl webctrl in this.Controls)<br />
{<br />
if (typeof(webctrl) is Image)<br />
{<br />
if (webctrl.ImageUrl.Equals("") == false)<br />
{<br />
++count;<br />
}<br />
else<br />
{<br />
img.Visible = false;<br />
}<br />
}<br />
}
Any idea? Thanks.

how does it evaluates the LOC - when you try to debug the line below
if (webctrl.ImageUrl.Equals("") == false)

Hallo,
I have a DataSet from 2 DB tables, and i want to databind some textboxes(say N, created dynamically) at runtime.
Is it possible to have 2-way databinding without using gridview or reapeater etc.
That is, i have a set of textboxes and labels in a table. The textboxes should implement 2-way databinding.
Thanks

Hi,
Can anyone help me with the following problem please;
I need to drop the 'www' part of a url whenever it is entered by a visitor. So for example if they type 'www.domain.com/' it goes to 'domain.com/'. Likewise it should do the same for specific files and folders eg 'www.domain.com/files/test.jpg' should redirect to 'domain.com/files/test.jpg'.
The updated domain name should be shown in the url.
I am running this on IIS on a dedicated machine over the web. I using the 'redirect' function in IIS i can only get it to redirect to a specific url rather than the exact corresponding file / domain location.
WOuld it be better to do this with a .Net config file?
Help greatly appreciated.
Thanks!!!

You may try like following code snippet
private string newUrl = System.Text.RegularExpressions.Regex.Replace("www.domain.com/files/test.jpg",
"^www\.", String.Empty);
Server.Transfer(newUrl);
Hope I answered you correctly

I'm trying to pass values within an insert statement, however, I'm not sure what is the best way to pass the most appropriate value to the taskID_PK column bigint identity. The identity column is normally filled in automatically.
An insert statement to the table returns the following error:
Cannot insert the value NULL into column 'taskID_PK', table 'teamwiki.dbo.task'; column does not allow nulls. INSERT fails.\rThe statement has been terminated."
VS 2005 / ASP.NET 2.0
SQL Server 2005 Express

How does the insert-statement look like? Do you set the identity column explicit?
Regards
Sebastian
p.S: Are you sure that the primary key is generated automatically?
|
|
|
|
|
Well the insert statement excludes this key, because I assumed  , that the behavior would be similar to that as when I update the table manually, for example:
"INSERT INTO [teamwiki].[dbo].[task]\r
([category_FK1]\r
,[sub_category_FK2]\r
,[ideal_delivery_date]\r
,[latest_delivery_date]\r
,[task_deadline]\r
,[request_date]\r
,[requesting_user]\r
,[assigned_to]\r
,[managed_by]\r
,[implementor_notes]\r
,[attachment] \r
,[last_update]\r
,[in_use])\r
VALUES (@category, \r
@sub_category,\r
@task_description,\r
@priority,\r
@status, \r
@ideal_delivery_date,\r
@latest_delivery_date,\r
NULL,\r
GETDATE(),\r
@requesting_user,\r
NULL,\r
NULL,\r
NULL,\r
NULL,\r
@in_use,\r
@product)" string
In my case, the primary key is named taskID_PK, as previously posted.
2. When I update data manually (e.g. through SQL Management Studio > right click on the table > Open table), the key is automatically incremented.
3. I created the table with an identity trigger simply using SQL Management Studio:
3.1 Taking a copy of the CREATE TABLE. Right click on table name > Script Table As > CREATE TO > New Query Window.
3.2 Dropping the table. Right click on the table name > delete.
3.3 Altering the CREATE TABLE statement to include identity:
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[task](
[taskID] [numeric] (2, 0) identity NOT NULL,
[task_description] [nvarchar](50) NULL,
[date_entered] [datetime] NULL,
[productID_FK1] [numeric](2, 0) NULL,
CONSTRAINT [PK_task_1] PRIMARY KEY CLUSTERED
(
[taskID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[task] WITH CHECK ADD CONSTRAINT [FK_task_product] FOREIGN KEY([productID_FK1])
REFERENCES [dbo].[product] ([productID])
GO
ALTER TABLE [dbo].[task] CHECK CONSTRAINT [FK_task_product]
Attempted solutions
-------------------
Since the key is a primary key, it doesn't accept any NULL values; it was recommended to use identity columns as opposed to a trigger that alters the table upon insert, because "it would be a computational suicide".
