I have found a blog post describing [one mechanism][1], but it involves a good deal of manual bookkeeping, including status flags, MouseMove events, manual "mouse leave" checking, etc. all of which I would rather not have to implement if it can be avoided.

<select id="opts" style="background-color: black; color: white;">
<option>first</option>

</select>
Safari is smart enough to make the small triangle that appears to the right of the text the same color as the foreground text.
Other browsers basically ignore the CSS, so they're fine too.
Firefox 3 however applies the background color but leaves the triangle black, so you can't see it, like this
I can't find out how to fix this - can anyone help? Is there a `-moz-select-triangle-color` or something obscure like that?

(DllNotFoundException) | I was testing on a customer's box this afternoon which has Windows Vista (He had home, but I am testing on a Business Edition with same results).
We make use of a .DLL that gets the Hardware ID of the computer. It's usage is very simple and the sample program I have created works. The Dll is [This from AzSdk][1].
In fact, this works perfectly under Windows XP. However, for some strange reason, inside our project (way bigger), we get this exception:
Exception Type: System.DllNotFoundException
Exception Message: Unable to load DLL 'HardwareID.dll': Invalid access to memory location. (Exception from HRESULT: 0x800703E6)
Exception Target Site: GetHardwareID
I don't know what can be causing the problem, since I have full control over the folder. The project is a c#.net Windows Forms application and everything works fine, except the call for the external library.
I am declaring it like this: (note: it's *not* a COM library and it doesn't need to be registered).
[DllImport("HardwareID.dll")]
public static extern String GetHardwareID(bool HDD,
bool NIC, bool CPU, bool BIOS, string sRegistrationCode);
And then the calling code is quite simple:
private void button1_Click(object sender, EventArgs e)
{
textBox1.Text = GetHardwareID(cb_HDD.Checked,
cb_NIC.Checked,
cb_CPU.Checked,
cb_BIOS.Checked,
"*Registration Code*");
}
When you create a sample application, it works, but inside my prj it doesn't. Under XP works fine. Any ideas about what should I do in Vista to make this work?
As I've said, the folder and its subfolders have Full Control for "Everybody".
Thanks in advance,

Amongst the capabilities of the CRM provider is for developers to author business logic in a Java like language and on events such as the user clicking a button or submitting a new account into the system, have validation and/or business logic fire off.
One of the capabilities that we make use of is for that business code running on the hosted provider to invoke web services that we host. The canonical example is a sales rep entering in a new sales lead and hitting a button to ping our systems to see if we can identify that new lead based on email address, company/first/last name, etc, and if so, return back an internal GUID that represents that individual. This all works for us fine, but we've run into a wall again and again in trying to setup a sane dev environment to work against.
So while our use case is a bit nuanced, this can generally apply to any development house that builds APIs for 3rd party consumption: <b>what are some best practices when designing a development pipeline and environment when you're building APIs to be consumed by the outside world?</b>
At our office, all our devs are behind a firewall, so code in progress can't be hit by the outside world, in our case the CRM provider. We could poke holes in the firewall but that's less than ideal from a security surface area standpoint. Especially if the # of devs who need to be in a DMZ like area is high. We currently are trying a single dev machine in the DMZ and then remoting into it as needed to do dev work, but that's created a resource scarcity issue if multiple devs need the box, let alone they're making potentially conflicting changes (e.g. different branches).
We've considered just mocking/faking incoming requests by building fake clients for these services, but that's a pretty major overhead in building out feature sets (though it does by nature reinforce a testability of our APIs). This also doesn't obviate the fact that sometimes we really do need to diagnose/debug issues coming from the real client itself, not some faked request payload.
What have others done in these types of scenarios? In this day and age of mashups, there have to be a lot of folks out there w/ experiences of developing APIs--what's worked (and not worked so) well for the folks out there?

(I'm not sure if obfuscator is the right word, it's one of the apps that takes your code and makes it very un-readable)

Previously I have often written data access classes that handled both reading and writing, which often led to poor naming, like FooIoHandler etc. The rule of thumb that classes that are hard to name probably are poorly designed suggests that this is not a good solution.
So, I have recently started splitting the data access into FooWriter and FooReader, which leads to nicer names and gives some additional flexibility, but at the same time I kind of like keeping it together, if the classes are not to big.
Is a reader/writer separation a better design, or should I combine them? If I should combine them, what the heck should I name the class?

<div class="input-line">
<input .../>
<a href="#" onclick="$(this).up().remove();" />
</div>
When the cloned input-line's removal link is clicked, it also removes any input-lines that were cloned from the same dom object. Is it possible to rebind the "this" object to the proper anchor tag after using cloneNode(true) on the above DOM element? | 0 |

It works on these records in multi-threaded batches. Each such batch writes to the same log file for creating a workflow trace for each record. Potentially, we could be making close to a million log writes in a day.
Should this log be made into a database residing on another server? Considerations:
1. The obvious disadvantage of multiple threads writing to the same log file is that the log messages are shuffled amongst each other. In the database, they can be grouped by batch id.
2. Performance - which would slow down the batch processing more? writing to a local file or sending log data to a database on another server on the same network. Theoretically, the log file is faster, but is there a gotcha here?
Are there any optimizations that can be done on either approach?

An example of the sort of relationship is that I have a table of orderlines. Orderslines have a foreign key relationship to Products and Products in turn have a foreign key relationship to ProductTypes.
I'd like to have a databound datagridview where each row represents an orderline, displaying the line's product and producttype.
Users can add or edit orderlines direct to the grid and choose the product for the orderline from a comboBoxColumn - this should then update the producttype column, showing the producttype for the selected product, in the same row.
The closest to a good fit I've found so far is to introduce a domain object representing an orderline then bind the datagridview to a collection of these orderlines. I then add properties to the orderline object that expose the product and the producttype, and raise relevant notifypropertychanged events to keep everything up to date. In my orderline repository I can then wire up the mappings between this orderline object and the three tables in my database.
This works for the databinding side of things, but having to hand code all that OR-mapping in the repository seem bad. I thought nHibernate would be able to help with this wiring up but am struggling with the mappings through all the foreign keys - they seem to work ok (the foreignkey lookup for an orderline's product creates the correct product object based on the foreign key) until I try to do the databinding, I can't get the databound id columns to update my product or producttype objects.
Is my general approach even in the right ballpark? If it is, what is a good solution to the mapping problem?
Or, is there a better solution to databinding rows including foreign key lookups that I haven't even considered? | c# | .net | winforms | null | null | null | open | WinForms databinding and foreign key relationships

I am developing a Struts web application which runs in a tomcat server. This is the environment i set up to work with UTF-8:
- I have added to tomcat's **conf/server.xml** the attributes **URIEncoding="UTF-8" useBodyEncodingForURI="true"** into the **Connector** tag.
- I have a **utf-8_general_ci** database
- I am using the next filter to ensure my request and responses are encoded in UTF-8
package filters;
import java.io.IOException;
import javax.servlet.*;
public class UTF8Filter implements Filter {
public void destroy() {}
public void doFilter(ServletRequest request,ServletResponse response, FilterChain chain)
throws IOException, ServletException {
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");
chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws ServletException {
}
}
- I use this filter in WEB-INF/web.xml
- I am using the next code for my json responses:
public static void populateWithJSON(HttpServletResponse response,JSONObject json)
{
String CONTENT_TYPE="text/x-json;charset=UTF-8";
response.setContentType(CONTENT_TYPE);
response.setHeader("Cache-Control", "no-cache");
try {
response.getWriter().write(json.toString());
} catch (IOException e) {
throw new ApplicationException("Application Exception raised in RetrievedStories", e);
}
}
Everything seems to work fine (content coming from the database is displayed properly and i am able to submit forms which are stored in UTF-8 in the database). The problem is that i am **not able to submit forms with AJAX**. I use JQuery and i thought the problem was the lack of contentType field in ajax request. But i was wrong. I have a really simple form to submit comments which contains of an id and a body. The body field can be in different languages such as spanish, german or whatever.
If i submit my form with body textarea containing *contraseña*, firebug shows me:
### Request Headers
- ***Host*** localhost:8080
- ***Accept-Charset*** ISO-8859-1, utf-8;q=0.7;*q=0.7
- ***Content-Type*** application/x-www-form-urlencoded; charset UTF-8
If i excecute in Firebug *Copy Location with parameters* the econding seems already wrong
http://localhost:8080/Cerepedia/corporate/postStoryComment.do?&body=contrase%C3%B1a&id=88
This is my JQuery code:
function addComment() {
var comment_body = $("#postCommentForm textarea").val();
var item_id = $("#postCommentForm input:hidden").val();
var url = rooturl+"corporate/postStoryComment.do?";
$.post(url, { id: item_id, body: comment_body } ,
function(data){
/* Do stuff with the answer */
}, "json"); }
A submission of a form with JQuery is causing the next error server side (Note i am using hibernate).
**Any help or ideas is really appreciated.**

| ajax | jquery | encoding | null | null | null | open | Problems while submitting a UTF-8 form textarea with JQuery/AJAX
===
I am having problems submitting forms which contain UTF-8 strings with Ajax. I am developing a Struts web application which runs in a tomcat server. This is the environment i set up to work with UTF-8:
- I have added to tomcat's **conf/server.xml** the attributes **URIEncoding="UTF-8" useBodyEncodingForURI="true"** into the **Connector** tag.
- I have a **utf-8_general_ci** database
- I am using the next filter to ensure my request and responses are encoded in UTF-8
package filters;
import java.io.IOException;
import javax.servlet.*;
public class UTF8Filter implements Filter {
public void destroy() {}
public void doFilter(ServletRequest request,ServletResponse response, FilterChain chain)
throws IOException, ServletException {
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");
chain.doFilter(request, response);
}
public void init(FilterConfig filterConfig) throws ServletException {
}
}
- I use this filter in WEB-INF/web.xml
- I am using the next code for my json responses:
public static void populateWithJSON(HttpServletResponse response,JSONObject json)
{
String CONTENT_TYPE="text/x-json;charset=UTF-8";
response.setContentType(CONTENT_TYPE);
response.setHeader("Cache-Control", "no-cache");
try {
response.getWriter().write(json.toString());
} catch (IOException e) {
throw new ApplicationException("Application Exception raised in RetrievedStories", e);
}
}
Everything seems to work fine (content coming from the database is displayed properly and i am able to submit forms which are stored in UTF-8 in the database). The problem is that i am **not able to submit forms with AJAX**. I use JQuery and i thought the problem was the lack of contentType field in ajax request. But i was wrong. I have a really simple form to submit comments which contains of an id and a body. The body field can be in different languages such as spanish, german or whatever.
If i submit my form with body textarea containing *contraseña*, firebug shows me:
### Request Headers
- ***Host*** localhost:8080
- ***Accept-Charset*** ISO-8859-1, utf-8;q=0.7;*q=0.7
- ***Content-Type*** application/x-www-form-urlencoded; charset UTF-8
If i excecute in Firebug *Copy Location with parameters* the econding seems already wrong
http://localhost:8080/Cerepedia/corporate/postStoryComment.do?&body=contrase%C3%B1a&id=88
This is my JQuery code:
function addComment() {
var comment_body = $("#postCommentForm textarea").val();
var item_id = $("#postCommentForm input:hidden").val();
var url = rooturl+"corporate/postStoryComment.do?";
$.post(url, { id: item_id, body: comment_body } ,
function(data){
/* Do stuff with the answer */
}, "json"); }
A submission of a form with JQuery is causing the next error server side (Note i am using hibernate).
**Any help or ideas is really appreciated.**

I've got a problem here with an MSI deployment that I'm working on (using Installshield)
we have a program running in the background that needs to run per-user, this needs to start automatically without user intervention.
The problem is with GPO/AD deployment the application is started in the SYSTEM context before anyone is logged in rather than as the user who is about to log in. The application can only run once per user, and it seems that the SYSTEM process prevents the USER process from starting. This means the PCs need to be rebooted twice before the software can be deployed to the users. Any ideas how to stop this?
Basically the current workflow is:
1. Installation/upgrade runs... kill background app
2. install new files
3. Startup background application
this works for Published applications and interactive MSI installations - it's only 'Assigned' applications that seem to have the problem. As step 3 happens in the SYSTEM context rather than the user context :(
Ideally I'd have the development team patch the EXE to prevent launching in the SYSTEM context, but that's a release cycle away and I'm looking for an installer based solution for the interim.
(Edit: I don't know Installscript... so I'm guessing VBscript is probably the way to if there's no native Installshield stuff I can use) | msi | installer | windows-installer | installshield | installation | null | open | stopping MSI from launching an EXE in the SYSTEM context

The software we are currently developing is a pretty big project. It consists of a client environment, an application server, various databases, web services host etc.
The project is developed incrementally and we want to ship the bits in intervals of one to two months. The first deliveries will not be used in production. They have the puropse of a demo to encourage the customers to give feedback.
We don't want to put burden on the customers to install and configure the system. All in all we are looking for a way to ease the deployment, installation and configuration pain.
What I thought of was to use a virtualizing technique to preinstall and preconfigure a virtual machine with all components that are neccessary. Our customers just have to mount the virtual image and run the application.
I would like to hear from folks who use this technique. I suppose there are some difficulties as well. Especially, what about licensing issues with the installed OS?
Perhaps it is possible to have the virtual machine expire after a certain period of time.
Any experiences out there?

Can someone please tell how I can colour the following code:
> lblMessage.Text = "You have successfully answered my question!"
I have the string coloured pink, I would like the lblMessage purple and the .Text a light green.
For me the darker the colour the less it will "change". I won't often change object names, I'll more often change properties and am always changing strings - although I have another question about this that I'll post later.
Thanks
