Hello Friends!
I've faced a probelm. pls help me.
I am trying to verify whether the path to the webservice hosted in iis is valid by the following code.
HostingEnvironment.VirtualPathProvider.FileExists("http://localhost/WSClientProxy/teste.asmx");
But every time it displays "'http://localhost/WSClientProxy/teste.asmx' is not a valid virtual path."
How can I get the virtual path?
Thanks!

Hi, Samrat.
The problem is that you're trying to use a file system routine (FileExists) with the virtual web url path that the browser uses. As you might suspect, these are completely different things.
MapPath() (I think it's in the Server namespace) will take a virtual path like "~/WSClientProxy/teste.asmx" and give you back a physical path to the filesystem. For example, MapPath("~/WSClientProxy") will give you the physical directory pointed to by this virtual path. You can then use that directory to create files, etc. and of course you can use MapPath("~/WSClientProxy/teste.asmx") as the parameter to FileExists(). If you play around with it and do some tests with creating, renaming (MoveTo()) deleting files, etc., I think you'll get the hang of it.
Hope this helps!

Looks like SMTP server is not installed on your machine. Check that in the IIS settings.

I've been working with ASP .NET and data for a couple months now. I'm creating a web app that is more or less a "virtual worksheet" with multiple choice questions. I get the question text and four answers from an Access database. Using data from an invisible GridView, I create Labels and RadioButtonLists at runtime and add them inside a View in my MultiView.
For I As Integer = 0 To Me.gvQMultipleChoice.Rows.Count - 1<br />
Dim lbl As New Label<br />
lbl.ID = "lblQ" & I<br />
lbl.Text = I + 1 & ". " & Me.gvQMultipleChoice.Rows(I).Cells(0).Text<br />
Me.vw1.Controls.AddAt(Me.vw1.Controls.Count - 5, lbl)<br />
Dim rad As New RadioButtonList<br />
rad.ID = "rad" & I<br />
For I2 As Integer = 0 To 3<br />
rad.Items.Add(SwitchChar(I2) & ". " & Me.gvQMultipleChoice.Rows(I).Cells(I2 + 1).Text)<br />
Next<br />
rad.RepeatDirection = RepeatDirection.Horizontal<br />
Me.vw1.Controls.AddAt(Me.vw1.Controls.Count - 5, rad)<br />
Next
Basically, make a Label, get its question text, add it to the View. Same with the RadioButtonList. This works fine. My problem is later, when I am trying to find out which RadioButton is selected. Me.vw1.Controls doesn't contain any of these Labels or RadioButtonLists.
<br />
Dim myControls As ControlCollection = Me.vw1.Controls<br />
For I As Integer = 0 To myControls.Count - 1<br />
If myControls(I).ID <> Nothing Then<br />
If myControls(I).ID.StartsWith("rad") Then<br />
Dim rad As RadioButtonList = Me.vw1.Controls(I)<br />
ans &= rad.SelectedIndex<br />
Else<br />
'ignore<br />
End If<br />
End If<br />
Next
This should work fine, I'm confident it would. But again, the problem is that the dynamically created controls aren't in the list. Does anyone know why it would be like this.
By the way, the Labels and RadioButtonLists show up, and I can select a RadioButton. The second bit of code is executed on a Button.Click event.
Thanks!
(Yes, this also in the Web Dev section. Sorry I posted there first.)

When do you add the controls ? If you add them in the prerender event, then the issue is that the click event fires first.

The controls are added in the View.Activate event. Yes, the same view that contains the dynamically-added controls and the Button that is clicked.

OK, I'm not familiar with that event, I'd set breakpoints to see if it's called after you search for the controls or not.

It's just the event that fires when the MultiView's ActiveViewIndex property is changed and the View begins to load.

Hi
<asp:Menu ID="Menu1" runat="server" OnMenuItemClick="Menu1_MenuItemClick" Orientation="Horizontal"><br />
<Items><br />
<asp:MenuItem Text="Main Menu" Value="Test"><br />
<asp:MenuItem Text="Second" Value="secondform.aspx"></asp:MenuItem><br />
<asp:MenuItem Text="Third" Value="thirdform.aspx"></asp:MenuItem><br />
</asp:MenuItem><br />
</Items><br />
</asp:Menu><br />
<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"><br />
</asp:ContentPlaceHolder>
and my Menu1_MenuItemClick event is:
protected void Menu1_MenuItemClick(object sender, MenuEventArgs e)<br />
{<br />
Server.Transfer(((System.Web.UI.WebControls.Menu)(sender)).SelectedValue); <br />
}
When I click the menu item, URL show the previous SelectedValue. Not the page is currently shown.
Any help would be appreciated.
Thanks

I have a field in the database which is of type date time. When i return it in a grid view I want to remove the time and show only the date. Is it possible to show only the date? Thank you.
PS I am showing the date by binding the grid view.

The MSDN documentation has an article[^] on date/time format strings.

Ofcourse its possible,
use substring() in sql.
bofore dispaly data in the grid use substring in db
|
|
|
|

You can do a Convert(varchar, dateTime field, 105) for instance.

Date formatting should be done in the presentation layer. The .NET Framework provides built-in support for this. See the link in my original reply.
|

I think it CAN be done in .NET
Let the poster of this problem decide what he wants to.
things like:
DateTime dateValue = DateTime.Now
String whatTime = String.Format("{0:yyyyMMdd}", dateValue);
can also be done.

This forum is a place for people to discuss solutions to problems. If I want to critisize other people's suggestions, I will do. I certainly don't need your permission.
The basic fact of the matter is that using the T-SQL SUBSTRING is a clumsy way to format dates. If T-SQL must be used, the CONVERT function is better. IMHO, .NET provides a much richer API for data presentation and should be the tool of choice.

This isn't the right way to do it. The .NET Framework has support for formatting dates in different ways. See the link I provided in my original reply.

Hello
I'm having trouble uploading images to my sql express database. I have been searching endlessly to find a solution to my problem but to no-avail, I now turn to the trusted codeproject network for some help in solving the answer. I'm new to asp.net and am currently building an application to upload images into a database. I found the following tutorial()[^] and manipulated it to use a stored procedure. Below is the code in my code behind page:
Protected Sub btn_upload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_upload.Click
Dim intLength As Integer
Dim arrContent As Byte()
If File_Upload.PostedFile Is Nothing Then
lbl_status.Text = "Please specify an image to upload"
Exit Sub
Else
Dim Filename As String = File_Upload.PostedFile.FileName
Dim ext As String = Filename.Substring(Filename.LastIndexOf("."))
ext = ext.ToLower
Dim image_type = File_Upload.PostedFile.ContentType
If ext = ".jpg" Then
ElseIf ext = ".bmp" Then
ElseIf ext = ".gif" Then
ElseIf ext = "jpg" Then
ElseIf ext = "bmp" Then
ElseIf ext = "gif" Then
Else
lbl_status.Text = "Only gif, bmp, or jpg format files supported."
Exit Sub
End If
intLength = Convert.ToInt32(File_Upload.PostedFile.InputStream.Length)
ReDim arrContent(intLength)
File_Upload.PostedFile.InputStream.Read(arrContent, 0, intLength)
If Upload_File_Server(txt_Image_Title.Text.Trim, arrContent, intLength, image_type) = True Then
lbl_status.Text = "Image uploaded successfully"
Else
lbl_status.Text = "An Error occurred while uploading please try again"
End If
End If
End Sub
Protected Function Upload_File_Server(ByVal title As String, ByVal Content As Byte(), ByVal Length As Integer, ByVal strType As String) As Boolean
Dim command As New SqlCommand("Upload_Article_Image")
conn.Open()
Try
command.CommandType = CommandType.StoredProcedure
command.Parameters.AddWithValue("@Content", Content)
command.Parameters.AddWithValue("@Title", title)
command.Parameters.AddWithValue("@Type", strType)
command.Parameters.AddWithValue("@Length", Length)
command.ExecuteNonQuery()
Return True
Catch ex As Exception
Return False
Finally
conn.Close()
End Try
End Function
The problem I am having is that the information is not being stored in the database and the function throws up the exception. If anyone can help me it would be greatfully appricated.
Regards
McGann
