<asp:xml> snag - this is killing me! - Web Development Discussion Boards

1) name the bitmap with the same full ( namespace+classname ) name as the webcontrol
1a) i've heard that the bottom left hand cornor pixel is marked as the "transparent color" for the icon.

2) set the following attribute:
ToolboxBitmap( typeof( Bitmap ) )
this means that the toolbox icon will be embeded in the assembly as a bitmap with the same name as the control.

if you are in visual studio...
3) add the bitmap to the project
4) set the compile type to embeded resource

if not
3) add the following arg to the compile command line
/resource:"C:\path\to\my\bitmap.bmp"

now when you compile it... you should see it in the toolbox.

First, if either in Visual C# or Visual Basic, you should not have to name the bitmap in "namespace+classname" format, because once you add a image or other non-XML resource into the project,the computed manifest res name of the resouse would be "rootnamespace.xxxxxxx", in other words we don not need add namespace manually.

Second, and this is the most important, ToolboxBitmapAttribute will set the icon as file or assembly resource, although you mentioned assign a bitmap resource with the same assembly name as the control, the usage of "typeof(Bitmap)" is wrong, because the attribute need specify an assembly type or name where can find the icon. The type is the control itself, we already embed a bitmap with the same assembly name as it.

Now, I made it. Thank you inprised me. and the following is the steps in Visual Studio.Net.

Create a WebControl Library project in VS.Net;

Add a WebCustomControl as name you specified, for example "MyCtrl1";

Add a 16*16 bitmap named "MyCtrl1.bmp" into the project, the name should be same as the classname of the control.

Set Select "MyCtrl1.bmp" in Solution Explorer and set File Property "Build Action" to Embedded Resource;

Modify the source code of the control like following:

namespace mylib
{
...
[
...
ToolboxBitmap(typeof(MyCtrl1)),
...
]
public class MyCtrl1 : WebControl ...
{
...
}

}

Then build the project.

Ah,yes, it appears that the Type parameter was wrong...
Some Microsoft guy told me to use Bitmap...
I always do, and it still Works For Me© Smile | :)

As for the namespace... What you have there must only work for Visual Studio, because if you leave off the namespace, it won't work from the command line compiler. VStudio must set something special in there somewhere Smile | :)

VStudio pre-pends the default namespace to images set as 'embedded resource'. No such thing exists for the commandline so you have to prepend the image filename yourself.

Hi,
all

I have create a new asp.net web service ,and I put the whole solution in the /wwwroot/webserive.
In another window application, I use "add new web reference " to import the web service .I input "http://localhost/webservice/helloworld.asmx" in the
address line,and then the system display a dialog to prompt
me to download the helloworld.asmx file to my own local machine. So I want to know why? Could I only use the web service on the condition that I download it to my own machine?

Your advaced help will be appreciated!

Regards.

Literally, I'm losing it here!

Simply want to transform an xml document with an xsl stylesheet using the <asp:xml> control. The documents will be dynamic based on a provided parameter (querystring, form value, whatever) so I'm using the DocumentSource and TranformSource properties in my code-behind file to dynamically assign the xml and xsl documents.

I repeatedly get this error:

"Object reference not set to an instance of an object."

Now, I don't get the error if I use the DocumentSource and TransformSource attributes in the xml web control like this:

<asp:xml id="detailsXml" documentsource="file.xml" transformsource="file.xslt" runat="server"/>

Here is some code:

using System;
using System.Collections;
using System.ComponentModel;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.Xml;
using System.Xml.Xsl;

public class PFDetailsPage : System.Web.UI.Page
{
//xml web control
protected Xml detailsXml;

private void Page_Load(object sender, System.EventArgs e)
{
//xml and xsl files
string xmlFile = Server.MapPath("xdetails/details.xml");
string xslFile = Server.MapPath("xdetails/details.xslt");

//call transform method below
TransXmlFile(xmlFile, xslFile);
}

public void TransXmlFile(string xmlFile, string xslFile)
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(xmlFile);
detailsXml.Document = xmlDoc;

XslTransform xslDoc = new XslTransform();
xslDoc.Load(xslFile);
detailsXml.Transform = xslDoc;
}
}

I also tried just doing this but got the same exact error on the same lines of code:

private void Page_Load(object sender, System.EventArgs e)
{
string xmlFile = Server.MapPath("details.xml");
string xslFile = Server.MapPath("details.xslt");
detailsXml.DocumentSource = xmlFile;
detailsXml.TransformSource = xslFile;
}

I'm absolutely sure the files are there, as I said, I had no problem using static values in the web control itself, it's only when I try to provide it values manually in my code-behind class that I start getting errors.

Thanks ahead of time!!

Do you set detailsXml to New somewhere?

I think protected Xml detailsXml; has to be public.

I'm a little perplexed with what would be a fairly simple linkage issue with C++.

When you create a new custom server control for an ASP.Net page and want to use it you must specify an Assembly location in the "Register" statement. MSDN says to compile it and place it in a Bin directory in the project path. I've done that but cannot get the page to recognize the existence of the assembly. So, where does it go in order for the page to find it? I'm fairly certain that I have something configured incorrectly in my development environment, but can't seem to locate the problem.

i.e.

<%@ Register TagPrefix="MyControl" Namespace="CustomControls" Assembly="Control1"%>

Where does "Control1" go?

"There's a slew of slip 'twixt cup and lip"

It is supposed to go in the /bin directory. Is Control1 the name of the dll? (Control1.dll)?

Did you figure out a solution to your problem? I'm having the same problem.

Todd Smith

I had my control in a subdirectory of the web root

\webroot\test\bin\mycontrol.dll
\webroot\test\mycontrol.aspx

That gave me the following error

File or assembly name MyControl, or one of its dependencies, was not found.

To fix it all I had to do was move the \bin dir to the root

\webroot\bin\mycontrol.dll
\webroot\test\mycontrol.aspx

and it worked!

Todd Smith

My problem was basically the same thing - it was not in the directory I thought it was in.

I know, I know this is not a place to ask about CGI.. but maybe someone can clarify to poor Microsoft's technologies programmer.... what is that? Smile | :)

Are there many types of CGI? Perl, PHP, whatever? I just got some web space on Linux machine with CGI support, and have no idea what to do with it Big Grin | :-D

I went to sites with free CGI scripts and uploaded some (they said it is Perl, but the file extention is PHP), but it is not working, just displaying me all source of the file Roll eyes | :rolleyes:

So what sgould I do with this scripts?? Confused | :confused:

Need Web-based database administrator? You already have it!

Usually to use CGI scripts you need to upload them into a folder designated by your ISP, usually something like : /cgi-bin/, you may also need to check that the scripts have executable rights ( based on server type at the ISP end of things ).

The type of scripts you refer to are basically just different languages ( like ASP or JSP ). The script could also just be an executable file written in c++, VB or whatever ( check the server type before trying to run these though ).

Oh, thanx... well, I played some, and I should say.... it is sucks, lol. Old CGI scripts on Perl are only supported, without any database.... I really have nothing to do with it Smile | :)

Need at least a database to do something.

I downloaded some scripts and installed them. Imaging a message board without a database, lol. All things stored in text files, which are parsed in script, uh uh uh. Along with passwords for editing messages, LMAO.

Well, one more time the statement "Free cheese could be only in a mousetrap" confirmed, lol

plain jane text files are fine in some circumstances.

Storing user's preferences I think would be acceptable.

Hello all,

I am trying to put a calendar control in an html page and then allow the user to select a date and then when he submits the form I want to pass the selected date to my ASP script.

I inserted the control using Visual Studiu 7 and it gave me this code :-

<OBJECT name="Calendar1" id="Calendar1" classid="clsid:8E27C92B-1264-101C-8A2F-040224009C02" >
<PARAM NAME="_Version" VALUE="524288">
<PARAM NAME="_ExtentX" VALUE="7620">
<PARAM NAME="_ExtentY" VALUE="5080">
<PARAM NAME="_StockProps" VALUE="1">
<PARAM NAME="BackColor" VALUE="-2147483633">
<PARAM NAME="Year" VALUE="2002">
<PARAM NAME="Month" VALUE="3">
<PARAM NAME="Day" VALUE="31">
<PARAM NAME="DayLength" VALUE="1">
<PARAM NAME="MonthLength" VALUE="1">
<PARAM NAME="DayFontColor" VALUE="0">
<PARAM NAME="FirstDay" VALUE="7">
<PARAM NAME="GridCellEffect" VALUE="1">
<PARAM NAME="GridFontColor" VALUE="10485760">
<PARAM NAME="GridLinesColor" VALUE="-2147483632">
<PARAM NAME="ShowDateSelectors" VALUE="-1">
<PARAM NAME="ShowDays" VALUE="-1">
<PARAM NAME="ShowHorizontalGrid" VALUE="-1">
<PARAM NAME="ShowTitle" VALUE="-1">
<PARAM NAME="ShowVerticalGrid" VALUE="-1">
<PARAM NAME="TitleFontColor" VALUE="10485760">
<PARAM NAME="ValueIsNull" VALUE="0">
</OBJECT>

Now how do I pass it to my ASP.
I tried get and post and nothing works Frown | :-(

I tried this from a button's javascript handler and it gave me errors. The error was "Invalid Callee" :-

<script language="javascript">
function abc()
{
alert(Calendar1.Year);
}
</script>

Can someone give me some pointers please?

Cry | :((

Nish

Has anyone seen my sig?

Nish,

I don't know if I got this right, but insert this after </object>:

<script language="vbscript">
Sub ShowYear()
  MsgBox Calendar1.Year
End Sub
</script>
<input type="button" onClick="ShowYear()" value="Show Year">

Have anyone used the Script Encoder? I didn't find any info which IIS supports it and other requirements. But looks like very useful thingy (for server-side scripts, not client-side).

So if someone knows what are requirements, please respond Smile | :)
