Determine Age Of A Picture File?
Nov 18, 2010
using vb.net 2005
I am looping through a directory and grabbing a jpg filename if it matches certain conditions (shown in my code snippet below).
However there might be more than one jpg in the file with the same name string "BarneyIsCool" and in this case I need to get the newest file that contains "BarneyIsCool" .
my question: How do i determine which file is the newest (last one added to the folder) using my vb.net code? the relevant code snippet follows:

I have this code to insert a picture from database into an ImageControl on my ASP.NET form:
strConnString = "server=" + Server + ";database=" + DataBase + ";UID=" + UID + ";password=" + PASS + ";";SqlConnection MyConnection = new SqlConnection(strConnString);SqlCommand MyCommand = new SqlCommand("SELECT Pic FROM MEN WHERE ID=5", MyConnection);MyConnection.Open();SqlDataReader MyReader = MyCommand.ExecuteReader();if (MyReader.Read()){ byte[] m_MyImage = (byte[])MyReader["Pic"]; Response.BinaryWrite(m_MyImage);}
And I have this ImageControl on the form:
<asp:Image Width="88" Height="100" Runat="server" ID="m_Image" NAME="m_Image" />
but when I run the code, I see the picture big on the screen and not in my ImageControl.
i also put this in the form_load:
m_Image.ImageUrl = "MyPhoneBook.aspx?m_Image";my control is: m_Imagemy control ID is: m_Imagemy namespace is MyPhoneBook
but still dont work

I let my users upload picture files from a VB6 project. I can filter out all but the common file types (.jpg, .gif etc.) when sending to the FTP.
Is there a way to open the files with Asp.Net, without knowing the specific file type. Like FileName.* or something?

am trying to use the AsyncFileUpload control in ajax toolkit to upload a picture file, save the file on a location on the server's filesystem and display the picture file back to the client system. I have both the image and AsyncFileUpload controls inside an updatepanel but its seems the UploadedComplete server code is not firing when the file upload completes any clue?

So we're having this problem. A user goes to upload a file, and if it's above 10MB, it just kind of times out the page, and clears, and no good error is thrown to describe what happened. Ideally, we would like to examine the file size when the user chooses the file they want to upload but I don't know if this is even possible. Our framework is built with ASP.NET, VB.NET, and Javascript (and ExtJS 3.0), and it runs in IE.

I created a survey in vb.net where results are stored in an Excel file.Locally I can access and update the data of the file, but if I put online can not correctly access the excel file.How can I determine the absolute url of the file so, when a user submits the answers they can be inserted correctly in the excel file? Currently I use this to determine the location of the file:
Dim LocalizacaoFicheiro As String = String.Concat(Server.MapPath("."), "RespostasQuestionario.xlsx")

I have some processes that run without an HttpContext in an ASP.NET MVC web application. This process needs to be able to determine the physical path to the Contents directory of the application for reading/writing data. But, since it is without an HttpContext, I don't get to use fancy things like Server.MapPath and such.

How do you do this in ASP.NET? Prefer VB.NET :) I have a file in my App_Data folder called test.mov. It's 500 megabytes. I want to create an ASPX page where it fetches the file, and then displays for a label the approximate download time depending on the user's connection.
It should say
File: test.mov
approximate download time for your connection: 15 minutes

I'm building several user controls (ASCX) for my website and several of them are very similar in what they do. (As a side note, I must create unique UC's even if they're similar because I'm creating widgets for the new Telligent Community themeing system). For example, two of them are different but use the same front-end code to create a 2 or 3 tab panel where you can click a tab and it changes the data below. I have a single JS file to handle these tabs and the animations. I'm currently dynamically adding my JS file reference to the <head> from the user controls' code via:
Literal jsFile = new Literal();
jsFile.Text = string.Format("<script src="{0}"></script>", "/community/themes/test/js/tabbedCallout.js");
Page.Header.Controls.Add(jsFile);
If I have both of these controls on a page though, both will add this JS file reference. How can I do a check to see if it is already added from another control?

In my application I've allowed users to upload Excel 2003 .xls files, and import them into a Gridview. This has been working fine using the following connection string:
[Code]....
Now my users are using Excel 2003, 2007 or 2010, I need to allow the newer file extensions (.XLSX) to be accessible too.
Therefore, within the connection string above I presume I could change the Excel version from 8.0 to 9.0 or 10.0 respectively, but is there much difference between Excel 2007 and Excel 2010 files?
If so, is it possible to 'detect' the Excel file version so that I can use the appropriate connection string to read the data from the files?

I have a webpage that allows a user to download a specified file. When the file is ready to be fully downloaded (i.e I call the HttpResponse.End or HTTPRepone.Flush) the user is presented with a File Download dialogue.
Is there any way to determine what option the user has selected?
Have they Opened, Saved or Cancelled the File Download once the Flush or End has been sent?

When I open my ASP.NET site in IIS and try to open the .NET Trust Levels, I get an error message:
.NET Trust Levels There was an error while performing this operation.
Details:
Filename: ?C:inetpubwwwrootmyappweb.config
Line number: 445
Error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"),or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
I've checked a few places, but I haven't found anything that seems like it would be locking that setting. Is there a systematic way of determining where that setting is locked?
I'm using IIS 7.5 and .NET 3.5 sp1.

In order to avoid having to pass Data that goes in the master page of my site before every view in every controller I have created an ApplicationController that sets the data on its constructor... the problem with this approach is that one of the viewdatas I must pass is the url of the profile Image of the current logged in user.
[Authorize(Roles = "Administrator")]
public abstract class AdministratorController : Controller
{
private IPortalAdministratorServices _servicioPortalAdministrator;
public AdministratorController()
{
_servicioPortalAdministrator = new PortalAdministratorServices();
ViewData["associates"] = _servicioPortalAdministrator.getAssociates();
ViewData["picture"] = _servicioPortalAdministrator.GetPic();
public AdministratorController(IPortalAdministratorServices service)
{
_servicioPortalAdministrator = service;
}
}
and so my companies Controllers wich inherits from AdministratorController now doesnt have to set all that Data upon every View Call.
[Authorize(Roles = "Administrator")]
public class CompaniesController : AdministratorController
{
private ICompaniasServices _service;
public CompaniesController()
{
_service = new CompaniasServices(new ModelStateWrapper(this.ModelState));
}
public CompaniesController(ICompaniasServices service)
{
_service = service;
}
The problem is this: When I try to manually access the Companies Controller without actually being logged in the method GetPic() wont actually be able to get the picture url cause no one is logged in.. and these method is getting called in spite of the Authorize attribute....so now, even after being logged in the ViewData for the picture url has been permanently set to "unknown.png" Some of this code isnt mine.. I just discovered the bug but cant figure out how to fix it.
