Need Help To Achieve Asynchronous Pages Using iFrames

TheFan244-Aug-06 3:48

Hi,

I have an app that needs to do some sort of health checks on all database connection strings specified in the config file.

At the moment, I have a main aspx page that loops through all these db connection strings, and for each one of them, I dynamically add an iFrame which loads a secondary aspx page that does the checking of the connection. (I'm adding the iFrame into a placeholder control by the way).

My problem is, it looks like that the main page waits for all the iFrame to finish loading before they get rendered. What I want to achieve is, as soon as each connection string is tested, I want it to display the result at once on the main page.

Any ideas on how I can achieve this? Your help is much appreciated.

Thanks.

Cheers,
TheFan

so you want the main page to be rendered and sent to the browser before the pages in the frames are loaded?

I'm not sure that would work with the iframes and even if it did you might need to refresh them periodically to simulate an ongoing test cycle.

Another neat way to do this might be:

1. Just create the one 'main page'.
2. Add a javascript function to the header to set an interval.
3. When the interval function calls back, call a set of javascript functions that use XmlHttpRequest to request your secondary pages (the ones in your frames right now, that execute your database tests). Set the call back in the http request call. Set a page level variable to say that a page request for page xxxx is pending (so you don't start calling it more than once if the interval were to elapse), and check this value before making the http request.
4. When your xml http request callback is called, just do a document.write or something to say your test worked. Or keep the iframes in the mainpage (but don't set their source) and when the http request callback is fired, set their innerHtml to what you get back from the request.

I believe INPUTBOX is visual basic 6.0 utility to display a pop-up with programmer-defined text which usually contained a question/prompt for text information. The recipient of this pop-up would be enter in a text in a field in the pop-up and click OK on the pop-up.

The code I have been using for just a plain pop-up in asp.net - no field for data entry (just in case this is a start for getting to one that has a field for input) is

Public Sub ASPNET_MsgBox(ByVal Message As String)

System.Web.HttpContext.Current.Response.Write("" & vbCrLf)

System.Web.HttpContext.Current.Response.Write("alert(""" & Message & """)" & vbCrLf)

System.Web.HttpContext.Current.Response.Write("")
End Sub

In my asp code, I would call this subroutine to display a pop-up message like

ASPNET_MsgBox("Hello World")

or

Dim sampleMessage As string
sampleMessage = "basic stuff"
ASP_NET_MsgBox(sampleMessage)

The one catch on this asp.net pop-up subroutine is do not pass it a string containing double quotes. No pop-up will appear, no error message or nothing will happen....

Maybe you should write what exactly you want to do.

You can use System.Web.UI.HtmlControls.HtmlInput* controls, if this is what you have been asking about...

Not sure but one thing you can try is to go to the command line and execute
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

Problem with office automation

Hi,

We are trying to convert word and excel to html format, we are using late binding to support different version of office. We have already taken care of setting dcom security to interactive user and also we have given [B]'launch and active'[/B] and [B]'Access permissions'[/B] for aspnet(Network service in case of 2003) user.

The problem is it works absolutely fine in some systems, but it will not work in some systems and throws error as Unauthorizedaccess for CreateObject call.

The only difference i could see in working and non working system is, in working system dcom services of excel and word are running with name like "Microsoft Excel Application", but in nonworking system these servies are runnig with GUID like "00020812-0000-0000-C000-000000000046", and this is just a difference i saw I am really not sure whether problem is because of this only or not.

PS: We are no supposed to impersonate aspnet user, so in our web confgi we set impersoantion to false.

Your aspnet user does not have correct permissions to run that file ( the actual executable for word )

Is it possible to select date from the calendar and put the date to the detailsview?

blurMember3-Aug-06 23:48

3-Aug-06 23:48

The subject is abit incorrect.

Let me describe briefly;
I am doing a project in .NET 2.0. C#. I have DetailsView control where user can add date and occasion to the database, thus display it in a gridview. But I wish that user can select the date from the calendar instead of typing. What is the correct syntax to write the code when the date is selected from the calendar?

<code> protected void Calendar1_SelectionChanged(object sender, EventArgs e)
{
//DetailsView1. = Calendar1.SelectedDate.ToString("dd MMM yyyy");
}</code>

the source from design view
<code>
<asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" AutoGenerateRows="False" BackColor="LightGoldenrodYellow" BorderColor="Tan" BorderWidth="1px" CellPadding="2" DataKeyNames="Index" DataSourceID="ObjectDataSource2" DefaultMode="Insert" ForeColor="Black" GridLines="None">
<FooterStyle BackColor="Tan" />
<EditRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" />
<PagerStyle BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue" HorizontalAlign="Center" />
<Fields>
<asp:BoundField DataField="Date" HeaderText="Date" DataFormatString="{0:MM/dd/yy}" HtmlEncode="False" SortExpression="Date" />
<asp:BoundField DataField="Occasion" HeaderText="Occasion" SortExpression="Occasion" />
<asp:CommandField ShowInsertButton="True" />
</Fields>
<HeaderStyle BackColor="Tan" Font-Bold="True" />
<AlternatingRowStyle BackColor="PaleGoldenrod" />
</asp:DetailsView></code>

thanks in advance. Much appreciated.

Hi there. One suggestion is to substitute a TemplateField for your date's BoundField, add a TextBox and Calendar control to the EditTemplate, then use something like this for code:

protected void Calendar1_SelectionChanged(object sender, EventArgs e)
{
    // use the textbox's ID for "TextBox1" below"
    TextBox tb = (TextBox)DetailsView1.FindControl("TextBox1") 
    tb.Text = Calendar1.SelectedDate.ToString("dd MMM yyyy");
}

I just add the calendar control to the webform as usual and it works pretty fine. I hope it does not have any further errors.
