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>

I was wondering if anyone knew if connection pooling will work with an as/400 backend?
Thanks

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.

Hmmm, I've never experienced that.But I always use a simple HtmlTable for layout. If push comes to shove, you can try that instead.

Thanks, Senkwe. Actually, I figured it out last night. Turns out that I'd somehow set my WebForm to target Internet Explorer 3.0 or below, and since those browsers don't support controls being layed on top of one another, it wraps them in table tags. None of my controls were overlapping, so I guess the designer was just playing it safe.

I want to display a value as hours which is stored as seconds in a database so I need to convert the value when I bind it to a textbox control. Something like this:
<asp:textbox id="hours" size="3" text='<%# DataBinder.Eval(Container.DataItem, "interval") / 3600 %>' runat="server" />
On the submit side it's easy enough to convert it back to seconds but I'm not sure how to convert it on the aspx side. I can probably change the sql statement but I would like to avoid that. I would also like to avoid having to do the conversion in the page_load function. Can this be done?

The method I've used for this type of problem is to create a public method that formats the required output
<asp:textbox id="hours" size="3" text='<%# MyFunction(DataBinder.Eval(Container.DataItem, "interval", "{0}") )%>' runat="server" />
public string MyFunction(string strSeconds)
{
return int.Parse(strSeconds) / 3600;
}

That works. thx.
<asp:textbox id="hours" size="3" text='<%# Utils.SecsToHours(DataBinder.Eval(Container.DataItem, "hours").ToString()) %>' runat="server" />
public static string SecsToHours(string seconds)
{
try
{
int secs = Int32.Parse(seconds);
int hours = secs / 3600;
return hours.ToString();
}
catch
{
return "";
}
}

HI,
IIS is being a twat. It won't let users download .exes from my web site. They user gets a 404 when the input the URL when I know for a fact that the files are there. Could it be some sort of security 'feature' that is causing this? I have run the IIS lockdown tool in the past - is it possible that this has affected it?
By the way, HTML, ASP, JPG, GIF all work fine.
Cheers
|
|

|
|
For anyone that cares, I think this is due to IIS lockdown as it restricts the downloading fo some filetypes. I'l know better when I get home tonight and try it out.
|
|
|
|
|
Try setting the Application Settings (Home Directory) the Execute Permissions on None (or Scripts only).
Next check HTTP Headers, File Types for the Registered file type .exe (this must be application/octet-stream).
Succes!
|
|
|
|
|
Thanks for the response but it was the URLScan component of IIS Lockdown wheich was restricting the downloading of exes. God know why 
|
|
|
|
|
URLScan blocks exes because they might run on the server, depending on the configuration. You can comment out the exe extension in the DenyExtensions section of the urlscan.ini file [%systemroot%\system32\inetsrv\urlscan\urlscan.ini], or create an asp page to handle the request and Response.BinaryWrite the file.
