catalogXml.Tables[0].Columns["Price"].DataType = System.Type.GetType("int32");
catalogXml.ReadXml( path );
if( !catalogXml.HasErrors )
{
DataView dvCatalog = new DataView(catalogXml.Tables[0]);
lblSortExpression.Text = e.SortExpression;
dvCatalog.Sort = e.SortExpression;
dgProductList.DataSource = dvCatalog;
dgProductList.DataBind();
}
I can't change the data type after there is data in it and cannot access myTable before loading the data!
this somehow does not seem to work

have a look at the following link -

Same problem as yours.

Thanks, it was a great pointer.
One needs to declare a Dataset and datatable.
Add columns to table and specify the data type for the columns
and then load the data set with any value.
Really appreiciate your help.

Hi All,
I am working on a .Net library to be used within the organization. There are lot of configuration settings for the library. Now the question is whether i put all the configuration in the web.config file and access using the configsectionhandler interface or should i put the configuration in a seperate xml file and access using XML DOM.
One of the reason i asking this bcos if we change anything in the web.config file the whole application resets which i donot want.
Can anyone please tell me which one is a better approach and why ????
Thanxs in advance.

My personal view on this is "neither". Rather structure your library's methods and constructors so that they accept the settings as parameters. Then, it is up to the caller application to either hard-code the values or deal with the config file issue.
This approach also makes for easier unit testing your library, because your tests can easily deal with several different testing scenarios.

Hi Steven,
Thanxs for the prompt answer. Let me rephrase my question...
I have already made the library with librarys method and constructors that accept the settings as parameter. I am trying to make a wrapper class which will read from a settings file so that the developer doesnt have to write any code to pass setting data to the library. So actually i was looking for a solution whether to put the config settings in the web.config file or to put it in a seperate xml file. And which solution will be better...
Thanxs in advance.

Like you say, web.config is not always the best choice, although it is certainly the easiest.
Some options:
* Use a generalized config API, like Nini
* Use an external config file
* Use your own home grown config solution

below is what i have apparently it is not supported on windows server 2003:
Public Sub SendEmail(ToWho, Subj, Mess)
Dim objMail
Set objMail = Server.CreateObject("CDONTS.NewMail")
With objMail
.MailFormat = CDOMailFormatMime
.To = ToWho
.From = Application("Support_Email")
.Subject = Subj
.Body = Mess
.Send
End With
Set objMail = Nothing
End Sub
My software developer said i should replace it with:
Public Sub SendEmail(ToWho, Subj, Mess)
Dim objMail
Set objMail = Server.CreateObject("CDO.Message")
With objMail
'objMail.MailFormat = CDOMailFormatMime
objMail.To = ToWho
objMail.From = Application("Support_Email")
objMail.Subject = Subj
objMail.HTMLBody = Mess
objMail.Send()
End With
Set objMail = Nothing
End Sub
But it doesnt work either any help is appreceiated

Start with creating a scheme for your database.
Which tables you need, which fields ...
Creating your webapp from there seems easy enough... I think  .
Modifying your Dbase afterwards will take you right into trouble.
Good luck.

Hi,
I have an XML file, which contains several nodes like the ones below:
<saml:Attribute AttributeName="ssbAssertionVersion" AttributeNamespace="http://www.syntegra.com">
<saml:AttributeValue xmlns:saml="urn:oasis:names:tc:SAML:1.0:assertion">1.0</saml:AttributeValue>
</saml:Attribute>
- <saml:Attribute AttributeName="cn" AttributeNamespace="http://www.syntegra.com">
<saml:AttributeValue xmlns:saml="urn:oasis:names:tc:SAML:1.0:assertion">Doe Joanna B</saml:AttributeValue>
</saml:Attribute>
----> My objective is to , take the value present inside the tag, "saml:AttributeValue " and populate it in my custom grid control, which will accept the element name as a parameter and display its value.
Problems:
1. ELEMENT NAME IS THE SAME IN ALL THE NODES, "saml:AttributeValue".
2.I dont want to reframe a new xml file out of this present one, since it increases the processing time.
3.I cant give an xpath query, directly to the my custom grid control.it will accept only the element name of a xml file.
Please help me, if you can think of a logic, that has to finally make the 'saml:AttributeValue' element name unique,without reforming a new xml so that i can directly feed that into my grid control.
Thanks In advance,
Regs, Manivannan

I guess u need to save / download image, when u know its url using some procedure.
If this the case u can use WebClient.DownloadFile (simple), or use HttpWebRequest and HttpWebResponse.

How can i get asp.net to valid to xhtml 1.1? I keep getting errors on this line:
I assumed it was from the view state, and i set all the view states on my page(hammackj.com) to false and it still appears...any way around this?
|
|
|
|

Hi,
It is a bit difficult, because Asp.Net 1.1 doesn't support strict xhtml, but you can look at this article http://www.codeproject.com/aspnet/ASPNET2XHTML.asp[^].
But IMHO it is not that important to have valid pages now (better working, than valid  ) because .Net 2 (=Visual Studio 2005 = Whidbey) will support strict xhtml pages (I'm really looking forward to this new version!).

Thanks so much =) I modified it to work for 1.1 will hold me over till 2005 =)

I am trying to make a script using JavaScript to display images like Windows Picture Viewer.
This is what I have so far:
Gallery Beta 1[^]
I am having problems with my script online however. It seems to work fine locally, from what I can tell. The problem is I have the image loaded when a picture is clicked, however nothing happens the first time you click it, so you have to click it a second time for the image to be displayed properly. I've been looking through my code to see what I can do to fix it, but for the time being I am stumped. Here is my Java script:
window.onload = init;<br />
window.onresize = getSize;<br />

Hi,
I'm not sure if I can help .. i just quickly checked the code and I think, that the problem is that loading of image takes long time (this is why it works with second click - image is already in cache).
I would try putting code for resizing image into onload event handler of IMG where 'big' picture is displayed.
I'm really not sure.. but maybe..

Hi All,
I am running IIS 6.0 on Windows Server 2003, along with ActivePerl
5.8.2.808. I run ASPX pages along with CGI scripts. When exporting a
PDF file from an ASPX page via the Crystal Reports API, our website
has randomly generated an error stating that the exported PDF file
could not be accessed because it is in use by another process. Of
course, this file name is unique (based on the IIS SessionID), and no
other process should be accessing this file. After much digging, I
turned on auditing for the directory where the PDF file is created and
found some interesting things. Here's the security audit entry for
when the PDF file is created:
Object Open:
Object Server: Security
Object Type: File
Object Name: D:\webdir\pdfexport\bsosdefh15nlzu550n4i0q55.pdf
Handle ID: 2984
Operation ID: {0,67487325}
Process ID: 2204
Image File Name: C:\WINDOWS\system32\inetsrv\w3wp.exe
Primary User Name: NETWORK SERVICE
Primary Domain: NT AUTHORITY
Primary Logon ID: (0x0,0x3E4)
Client User Name: -
Client Domain: -
Client Logon ID: -
Accesses: READ_CONTROL
SYNCHRONIZE
ReadData (or ListDirectory)
WriteData (or AddFile)
AppendData (or AddSubdirectory or CreatePipeInstance)
ReadEA
WriteEA
ReadAttributes
WriteAttributes
Privileges: -
Restricted Sid Count: 0
Access Mask: 0x12019F
Now here's the next security audit entry that appears in the Event
Viewer when the random error occurs (the user is IUSR_XYZ, the
anonymous web user):
Handle Closed:
Object Server: Security
Handle ID: 2984
Process ID: 3768
Image File Name: C:\Perl\bin\perl.exe
It looks like perl.exe closes the same file Handle ID (2984) as that
which the PDF export process was using above.
Is the OS somehow assigning the same Handle ID to two different
processes (process #2204 and #3768)?
The next thing that happens is the ASPX page tries to write out to the
PDF file using the file Handle ID that was closed by Perl in the
previous entry. I think this is where the error occurs:
Object Access Attempt:
Object Server: Security
Handle ID: 2984
Object Type: File
Process ID: 2204
Image File Name: C:\WINDOWS\system32\inetsrv\w3wp.exe
Accesses: WriteData (or AddFile)
Access Mask: 0x2
Does anyone have any insight into the cause of this problem?
Thanks, Todd

Dear CPians,
I have noticed that Mozilla renders the padding style in a different way that IE and Opera do...
How can I overcome this problem?
Thank you!
