VS2003 - Echec de l'actualisation du projet

Après avoir fermé toutes les session de Visual Studio, Passer dans l'explorateur de fichier et aller dans le sous-répertoire :

- Documents and Settings
-- "userlogin" (login de l'utilisateur)
--- VSWebCache
---- "hostname" (nom de la machine)

Et supprimer le cache du projet qui pose problème (ou éventuellement de tous les projets).

Throwing from XSLT

From http://weblogs.asp.net/george_v_reilly/archive/2006/03/01/439402.aspx

I (George V. Reilly, not me) needed to add some declarative error checking to some XSLT templates recently. Specifically, I wanted to throw an error if my selects yielded an empty string, indicating that the input XML was wrong.

Unfortunately, there seems to be no easy way of doing this in XSLT, nor in XslTransform. The approved way is to validate against an XSD schema, but for various reasons, I didn't want to go to the hassle of creating one.

I found a partial solution using xsl:message with the terminate="yes" attribute. Under XslTransform.Transform() the following code throws an exception if the XPath expression is empty.

 <xsl:if test="not(/some/xpath/expression)">
     <xsl:message terminate="yes">Missing expression</xsl:message>
 </xsl:if>
 <xsl:value-of select="/some/xpath/expression" />

It doesn't do anything, however, in XMLSpy.

The downside, of course, is that you have to maintain the expression in two places, and the template becomes littered with those annoying tests.

The generated html is inspired by the one used on Hot Links (http://dev.upian.com/hotlinks/). It can be styled with the following css:

.bm_blogmarks {
	margin: 10px auto;
	padding: 1%;
	background-color: #f5f5f5;
	border: 1px solid #d9d9d9;
	width: 97%;
	overflow:auto;
}
.bm_even {
    background-color: #fcfcfc;
}
.bm_blogmarks h4 {
	margin-top: 0;
}
.bm_blogmarks p.bm_tags {
	margin-bottom: 0;
	display: block;
	clear: left;
}
.bm_blogmarks img {
	margin: 0 0px 5px 10px;
	float: right;
	border: 0;
	clear: none;
	width: 144px;

}
.bm_even img {

Build GoogleSearchService.dll from GoogleSearch.wsdl

To generate the C# stub source type:

wsdl GoogleSearch.wsdl

This will result in GoogleSearchService.cs.
Compile with:

csc /target:library GoogleSearchService.cs
(or mcs /target:library GoogleSearchService.cs for mono)

Now you have the final stub assembly: GoogleSearchService.dll

How to work around the "double-click" problem

This is a generic method to avoid "double-click" effect where a user click many times to validate. The button is hidden when the user clicks it. In order to not update all forms, the trick is applied to the Render event of the page.

protected override void Render(HtmlTextWriter output) {
    // Get normal html ouput
    StringBuilder stringBuilder = new StringBuilder();
    StringWriter stringWriter = new StringWriter(stringBuilder);
    HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
    base.Render(htmlWriter);
    string html = stringBuilder.ToString();
    // Enhance submit buttons
    string onclick1 = "\"if (typeof(Page_ClientValidate) == 'function') Page_ClientValidate();";
    string onclick2 = "\"this.style.display='none';";
    html = html.Replace("onclick=" + onclick1, "onclick=" + onclick2 + onclick1.Substring(1));
    // Render updated html
    output.Write(html);
}
