hi all, i m enhancing web applicaiton in vs 2003,it uses the softartisian software for file uploading,i have made a function for file uploading,when that function is called from asp:button handler it works fine,but when i call that function from Ajax,it gives above mentioned exception,here is the code that is in function

<br />
 pFileUp = new SoftArtisans.Net.FileUp(Context);//it works <br />
 SoftArtisans.Net.SaFile file = (SoftArtisans.Net.SaFile)   pFileUp.Form["file1"];//this line raises exception<br />

i m u this code from javascript

xmlhttp.open("GET", url, true);
xmlhttp.send(null);

function it works fine when i call that from code behind of server control button handler, but not when from java script query string method of calling function

I am not sure, but have you tried the POST method instead of GET..

retreiving data from databse to web page

hi
i wanted to ask that how can we retreive the values from a databse and write them on to the web form

i used the code below to just retreive one column, though the browser gave me a errr. it stated that message recieved from server could not be parsed.. exception.. and that too when i had exception handling in place..

while (dread.Read())<br />
{<br />
Response.Write(dread["Firstname"]);<br />
}

any ideas..

first check if you are getting data in dread i.e datareader
then cast to string

Response.Write(dread["Firstname"].ToString());

i did try that and also checked with Console.Write(dread[0])

but when i tried with console... nuthing got printed.. though.. no error came..

also now how do i check whether dread has a value..
when i debugged.. it does follow the loop... though the VIsibleFiledCOUnt = 12
i guess that means it has data..

Hello

I want to make that the users from my Website can visit they're Profile over the websiteurl/username. I have read, that i have got to use url rewriting (into Application_BeginRequest)to handle this. Now if I want to use it this way, there must exist a Folder with the username and a Default.aspx File into it. Otherwise it will never reach the global.asax File and i can't change the URL.
Do I really have to create this Folders and Files or can i add something into the IIS or so?
I thought also about the possibility to change the 404Error File into an .aspx File and handle it there. Is this the solution?

Best regards
succo

Issues in Word Automation

I am using Visual Studio .NET 2003 to develop the application. My issue is that i had to generate a Word Report with password from an ASP.NET web application.
After much try i got the dll Microsoft Word 11.0 Object Library and with the help of which while trying to generate a word document with password from a application it was throwing a runtime exception.I had to imersonate the user as it showed an acces violation.

COMException (0x800a175d): Could not open macro storage.

When performed a search with this, i came to know the necessity of configuring the Word application of the server with DCOMCNFG - as setting the word to be run under interactive user mode etc. But that is very risky as listed in the links,

http://support.microsoft.com/kb/q288366/ -- (Explains how to configure with DCOMCNFG)

http://support.microsoft.com/kb/257757/

Can any body tell me how to solve this without using DCOMCNFG ?

The following link tells me that it can also be achieved by saving the
document as XML and manipulating the XML.

http://www.thescripts.com/forum/thread374627.html

Is it possible to set a password while generating with the XMl... i don't think that it is possible but still....

Then how to stream that file to the client ?

If any body could give me any suggestions or links i'll be grateful...!

Your suggestions might be of great value....

If anybody comes across any link or any thing please do reply ....

I will be very grateful...

I don't think you can solve it without using dcom config. This is a bad plan of attack though. Having Office installed on your server is bad enough. Opening Office with the ASPNet worker process is even worse. You don't want to do that.

Your best bet for sending word document to the client is to use SQL Server Reporting Services or Crystal Reports and exporting the report to MS Word Format.

Thanks Todd. But is there any way to set the password for the word document when not using a server side object or when not configuring with 'DCOMCNFG'.

How about being a little more specific? What are you trying to do? What have you tried? If you haven't tried anything, then do so before asking for help.

if u r using ASP.net, why dont u use the validation controls in it.. just drag and drop one..

for input date, use calendar extender in AJAX, and a reqd field validator on the text box.. this will easily do the job.

I write this code in webpart.aspx and add this file to my project:
<div >
<asp:WebPartManager ID="WebPartManager1" runat="server">
</asp:WebPartManager>
<table runat ="server" >
<tr >
<td>
<asp:WebPartZone ID="WebPartZone5" runat ="server" >
<ZoneTemplate >
<asp:Calendar ID="Calendar1" runat="server" Title="Time & Date" BackColor="White" BorderColor="#3366CC" BorderWidth="1px" CellPadding="1" DayNameFormat="Shortest" Font-Names="Verdana" Font-Size="8pt" ForeColor="#003399" Height="200px" Width="220px">
<TodayDayStyle BackColor="#99CCCC" ForeColor="White" />
<SelectedDayStyle BackColor="#009999" Font-Bold="True" ForeColor="#CCFF99" />
<OtherMonthDayStyle ForeColor="#999999" />
<TitleStyle BackColor="#003399" BorderColor="#3366CC" BorderWidth="1px" Font-Bold="True"
Font-Size="10pt" ForeColor="#CCCCFF" Height="25px" />
<NextPrevStyle Font-Size="8pt" ForeColor="#CCCCFF" />
<SelectorStyle BackColor="#99CCCC" ForeColor="#336666" />
<WeekendDayStyle BackColor="#CCCCFF" />
<DayHeaderStyle BackColor="#99CCCC" ForeColor="#336666" Height="1px" />
</asp:Calendar>

</ZoneTemplate>
</asp:WebPartZone></td> </div>

But this gives one problem at runtime i.e how to retain the webpart control, once closed by mistake? (at runtime).
I am not able to view the webpart once i closed it on runtime.
Another problem is that I am using vs2005 but I am not able to find webpartpagemenu control in web parts in toolbox

pls help

You need to add a catalog zone to your page. When switching the WebPartManager to catalog mode it will display and you can add any closed webparts back to the page.

There is no such thing as a webpartpagemenu control.

Do yourself a favor and do some research on the subject before trying to use it.
