I set mine up by either placing them inside a HTML table or by using the style tag.

What limitations exist for an ASP.NET webapplication as ragards a straight C# application.
I am trying to learn C# but I also need to know more about ASP.NET and since I can do the server side stuff in C# I thought I could combine the two tasks.
however I suspect that the c# in webapplications would be limited in someway - maybe not - but I'd like to know before I start racking my head over something I can't do

I am trying to deploy an ASP.Net project from my 2000 Pro box to my XP Pro box using the copy feature of VS.Net. I have successfully moved it to a 2000 Advanced server box. The problem is that when I try and move it to the XP box I am getting permission errors.
Now I have tried opening up the anonoymous access, logging on as Admin, etc and every conceivable thing I can think of with no luck. .Net simply refuses to allow me to copy the ASP.net app to this IIS server.
I have also verified that the 2000 Advanced server has the identical IIS settings as the XP box except for those settings that Advanced server provides which are not on the XP Pro version of IIS such as Operators.
Any thoughts as to why this is causing me such grief and how to fix it would be greatly appreciated

Have you tried making a 1 page ASP.NET project and seeing if you still get the same errors?
Cheers,

Actually the test case I am trying is a single ASPX file. It works if I pull the data to the server as opposed to puching it from my development box. Unfortunately I wouln't always have that luxury if I need to push to a third party host.

I have a datagrid with a lot of columns that I need to creat a sql update statement from. Most of the examples do something like the following:
TextBox hours = (TextBox)objArgs.Item.FindControl("hours");
TextBox days = (TextBox)objArgs.Item.FindControl("days");
TextBox userid = (TextBox)objArgs.Item.FindControl("userid");
.... repeat for all controls in the grid
string sql = "update userinfo set hours = " + hours.Text + ", days = " + days.Text + " where userid = " + userid.Text;
As you can imagine this take a lot of code for a table with a lot of columns.
Is there a way to enumerate the bound columns of a datagrid? Something like:
string sql = "update userinfo set ";
foreach (BoundColumn column in myDataGrid)
{
sql += column.Name + " = " + column.Text ", ";
}
would be really nice.

I believe you need to do it this way.
private void OnUpdate(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
TextBox text = (TextBox)e.Item.FindControl("Edit1");
Label label = (Label)e.Item.FindControl("Label1");
}

Hi all,
I have one iframe element on my aspx page. I want to pass the content of the
iframe back to the
codebehind file for saving to the database. Is there any way to grab this
information and post back?

Like subject says... I have problems when including a file more than once,
so having something like a #define would avoid including a file twice.
I'd also like to use that for creating a language file, so to translate my
website, I'd only have to modify that file...
Thanks!
I just found out that Const would do that for me, but now I need an equivalent to #ifdef, #else and #endif...

Hi All,
I am using ASP.NET and C#
I would presume this is an easy question but I can't seem to find any information about it.
I would like to add a button to my webpage that when clicked acts just like the print option of Internet Explorer. ie. Brings up a box to ask you what printer you want to print.
I'm sure there must be a straight function that I can call, something like Document.Print?
Thanks,
Gavin

code example:
<SCRIPT Language="Javascript">
function printit(){
if (window.print) {
window.print() ;
} else {
var WebBrowser = '<OBJECT ID="WebBrowser1" WIDTH=0 HEIGHT=0 CLASSID="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"></OBJECT>';
document.body.insertAdjacentHTML('beforeEnd', WebBrowser);
WebBrowser1.ExecWB(6, 2);
}
}
</script>
<SCRIPT Language="Javascript">
var NS = (navigator.appName == "Netscape");
var VERSION = parseInt(navigator.appVersion);
if (VERSION > 3) {
document.write('<form><input type=button value="Print this Page" name="Print" onClick="printit()"></form>');
}
</script>

What are your favorite ASP.NET sites for learning more complex stuff?

Start with www.asp.net? It is a Microsoft maintained site
|

There are many web hosting provider, but they don't support ASP ?.If you know any please tell me.
Thank you very much.

My "preferred" Hosting provider for ASP.NET is WebStrikeSolution.com! They offer a nice package for ASP.NET and the price is hard to beat! Check it out: http://www.webstrikesolutions.com/windows.html
I had been using the Web Hosting provided by my ISP (included with the service, however, the ISP Tech's just weren't up-to-speed with ASP.NET and I don't want to have to teach them as well as myself. So, I chose to switch and have been happy so far!

Sounds you're not linking odbc32.lib.
Don't know right now how to add it exactly (in .NET -> project properties, Linker, Input, Additional Dependencies)
Succes!

Hi all, I need a second opinion on this. Recently I've been struggling with trying to load user controls dynamically. Simple right. Well not if those user controls also host other user controls that are loaded dynamically. It's technically possible but all solutions I've seen so far haven't worked and they have been hacks. The main problem with loading user controls dynamically is keeping track of view state and wiring up events.
Now, one workaround I thought of was loading all the user controls at compile time (so that they are actually part of the page) and hiding/showing the desired controls depending on user input. I had thought that the resultant html source produced would end up becoming bloated with hidden controls. A quick test however, showed that the source ends up excluding all invisible controls, ie they are simply not rendered. So the resultant page is NOT bloated.
To prevent too much work being done on the server however, I thought you could test to see if the control was visible in which case you could safely call your data binding code for example, and if not, you simply do nothing when the control loads.
Well, what do you guys think? Is this how you do it as well? I'd like to hear pros and cons.

Why in the HELL does WebForm designer restructure my nicely formated code in to a bunch of table tags?!?!
Original Code:
<DIV style="WIDTH: 873px; POSITION: relative; HEIGHT: 320px" ms_positioning="GridLayout">
<asp:button id="cmdUpdate" style="Z-INDEX: 101; LEFT: 584px; POSITION: absolute; TOP: 264px" tabIndex="10" runat="server" Width="80px" Height="24px" Text="Update"></asp:button>
<asp:label id="Label8" style="Z-INDEX: 102; LEFT: 400px; POSITION: absolute; TOP: 16px" runat="server" Width="136px">Welcome Message:</asp:label>
etc...
After changing just ONE item in the designer:
<DIV ms_positioning="GridLayout">
<TABLE height="320" cellSpacing="0" cellPadding="0" width="873" border="0" ms_2d_layout="TRUE">
<TR vAlign="top">
<TD width="0" height="1"></TD>
<TD width="8"></TD>
<TD width="8"></TD>
<TD width="168"></TD>
<TD width="88"></TD>
<TD width="16"></TD>
<TD width="112"></TD>
<TD width="184"></TD>
<TD width="88"></TD>
<TD width="201"></TD>
</TR>
<TR vAlign="top">
<TD width="0" height="15"></TD>
<TD colSpan="3" rowSpan="2">
<input id="hdnID" type="hidden" runat="server" NAME="hdnID"></TD>
<TD colSpan="8"></TD>
</TR>
<TR vAlign="top">
<TD width="0" height="24"></TD>
<TD rowSpan="10"></TD>
<TD colSpan="2">
<asp:label id="Label1" runat="server" Width="152px" Height="16px">Client Name:</asp:label></TD>
etc...
This makes no sense to me, and is EXTREMELY frustrating, because when I go back to the designer, everything is completely misplaced.
Thanks in advance for any ideas.
