Hi All,
I have a web service that uses COM objects.
On most computes it works fine. But on some, when it tries to create the COM object, an error occurs:
Error creating COM object-Creating an instance of the COM component with CLSID {5B73CCB7-1371-11D3-910B-00C0F02C639B} from the IClassFactory failed due to the following error: 800aea5f.
The web services are running under user ASPNET. ASPNET, but default, is linked only to the Users group. If I link it to the Administrators group it works OK, but I don't want to do that.
In the past I had a similar problem and found that the directories my COM objects were in did not have for some reason Execute or Write access to the Users group. when I gave permission for these folders the problem was solved.
But now I have (well, the customer has) servers with the correct security permissions for all folder, but still the error occurs.
Any idea anyone?

Found it! 
My COM object is using an ODBC Data Source enry to open a connection to the database.
On the server where the error occurs, the SQL Server DSN Authentication is configured to use "With Windows NT authentication using the network login ID".
On the server where there is no error, the SQL Server DSN Authentication is configured to use "With SQL Server authentication".

MD5 or any custom.

I have a page with a textbox and a button. The button opens a dialog where the user selects a customer account number from a grid.
Once the selection is made, the dialog should close and the textbox on the parent page should now display the customer account number.
I did some research (I'm using ASP.Net 2.0) and it seems like I want to use something like this on the parent page:
void Page_Load(object sender, EventArgs e)
{
TextBox SearchTerm;
SearchTerm = (TextBox)Page.PreviousPage.FindControl("CustomerAccount");
Label1.Text = CustomerAccount.Text;
}
So I guess I would set the customer account field on the dialog and then close it ?

Hello All!

Thanks!

if you are doing it server side code use response.redirect(pathWithFilename.pdf)
and on clicent you can just give a link/button and open the pdf file like a href='http:\\url\file.pdf'

Hello Sabhatti!
Thank you for the quick response. That worked great, but I didn't realize it would open adobe. Is there a way to open a pdf file, while still in the webpage?
Thanks!
Rudy

hi
you can try this : convert the file into byte array,set the Response.ContentType to application/pdf and do a binary write
Sample code:
string filePath=Request.MapPath("a.pdf");
System.IO.FileInfo ofile=new FileInfo(filePath);
System.IO.FileStream fs = ofile.OpenRead();
int filelen=(int)fs.Length;
byte[] b=new byte[filelen];
fs.Read(b,0,filelen);
Response.ClearHeaders();
Response.ClearContent();
Response.ContentType="application/pdf";
Response.BinaryWrite(b);
Response.End();
Response.Flush();

Hi,
What is the advantage of this way over SABhatti's statement? Please explain me.

Hi A.R.!
What do you mean by converting the file into a byte array?
Thanks!

Hi,
I have a GridView with a TemplateField. The one control in the TemplateField is an ImageButton. It's a "Delete" button. The TemplateField and it's ImageButton are defined in the aspx page. However, there are some columns within the GridView that are being dynamically added, but not the TemplateField. It seems to bind and load fine on initial load of the page. Once the Delete button is clicked, though, the page does post back, but the ImageButton disappears and neither the GridView_RowCommand or ImageButton_Click events are triggered. In debugging I find the ImageButton is found on initial load during GridView_RowDataBound, but is not found (null), during the same event during PostBack. It also doesn't seem to matter whether, or not, I'm binding the GridView only during the initial load (!IsPostBack) or all the time. Is adding the other columns dynamically causing this? If so, how do I get around it? What am I missing?
Thanks

Usually, when I button is there initially and then disappears it is because it is defauled to visible = false in the UI / html. Then someplace in the page load probably in a
!IsPostBack the visible is set to true. That is usually where I have had my trouble with these things.
Hope that helps.

Afraid that's not the case here. The ImageButton is not set to Visible=false in the aspx and the visibility is not changed at all anywhere in the code-behind.

Hello,
I have a gridview that i want to make editable.
So i link it with a datasource, where I defined the updatecommand
In the edititemtemplate of my datagrid I have this dropdownlist
< asp:DropDownList ID="Field1" runat="server" ><br />
< asp:ListItem Value="OTH" Text="OTH">< /asp:ListItem><br />
< asp:ListItem Value="SGA" Text="SGA">< /asp:ListItem><br />
< asp:ListItem Value="COS" Text="COS">< /asp:ListItem><br />
< asp:ListItem Value="NA" Text="NA">< /asp:ListItem><br />
</a sp:DropDownList><br />
I tried to define the update command like that
<br />
< asp:SqlDataSource ID="SqlDataSource1" Runat="server"<br />
UpdateCommand = "UPDATE blabla SET Field1=@Field1<br />
WHERE Id_MAP =@original_M_IdMAP" .... ></pre><br />
<br />
But asp throws me this error during the executtion<br />
<br />
Must declare the scalar variable "@Field1 "<br />
<br />
What I need to do to resolve this problem ?<br />
<br />
thank you very much for your help<br />

Hi,
If I create a new web page (aspx)/ web service (asmx) in VS 2005, there is no namespace for the codebehind class.
I am trying to understand:
1. What is the intention behind this behavior?
2. Can I put my namespace myself, or rather SHOULD I ?
Thanks,
Atul

Yes you can and you should. I still haven't figured out why there is no namespace. I guess they figure you will add it if you want to.
