I realize that this question is perhaps more vague than is intended on stack overflow, so how about this? Please answer with one book or web site and a brief description. Then people can vote up their favourites.

I have an Image control with it's source bound to a property on an object(string url to an image). After making a service call, i update the data object with a new URL. The exception is thrown after it leaves my code, after invoking the PropertyChanged event.
The data structure and the service logic are all done in a core dll that has no knowledge of the UI. How do I sync up with the UI thread when i cant access a Dispatcher?
PS: Accessing Application.Current.RootVisual in order to get at a Dispatcher is not a solution because the root visual is on a different thread(causing the exact exception i need to prevent).

I want to build my own custom log4j (network) adapter to solve my problem [that I posted here.][1]
I have looked at the documentation on the log4j and I cant see where/if the developers go into how to do this.
Can anyone point me in the right direction to get started?

In many cases it will use WMI, but in some cases it may need to read remote registry or remotely execute some command or script on the polled system. These functions will require admin-level access to the polled systems. Now, I expect that in most use cases, there will be a domain, and the polling application can run as a service with Domain Admin (or equivalent) privileges, which means I do not have to worry about storing passwords - the admin setting up the app will define the service's username/password via standard Windows mechanisms.
But there's always a few black sheep out there. Systems for which we will have to define a username and password, store them securely, then invoke this user/pass pair at the time we poll that system. So keep in mind - in this case the program being written *is the user* who *sends* password to the authenticating system.
I am not sure whether I will need to use a reversible hash which I then decrypt to plaintext at time of use, or if there is some Windows mechanism which would allow me to store and then reuse the hash only. Obviously the second mechanism is preferable; I'd like my program to either *never* know the password's plaintext value, or know it for the shortest amount of time possible.

I have a DataAccess project that contains the LINQ to SQL classes, and a website project that is the UI. My database looks like this:
User -> MessageDetail <- Message <- MessageCategory
MessageDetail is a join table that also contains an IsRead flag.
The list of messages is grouped by category. I have two nested ListView controls on the page -- One outputs the group name, while a second one nested inside that is bound to MessageDetails and outputs the messages themselves. In the code-behind for the page listing the messages I have the following code:
protected void MessageListDataSource_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
var db = new DataContext();
// parse the input strings from the web form
int categoryIDFilter;
DateTime dateFilter;
string catFilterString = MessagesCategoryFilter.SelectedValue;
string dateFilterString = MessagesDateFilter.SelectedValue;
// TryParse will return default values if parsing is unsuccessful (i.e. if "all" is selected"):
// DateTime.MinValue for dates, 0 for int
DateTime.TryParse(dateFilterString, out dateFilter);
Int32.TryParse(catFilterString, out categoryIDFilter);
bool showRead = MessagesReadFilter.Checked;
var messages =
from detail in db.MessageDetails
where detail.UserID == (int)Session["UserID"]
where detail.Message.IsPublished
where detail.Message.MessageCategoryID == categoryIDFilter || (categoryIDFilter == 0)
where dateFilter == detail.Message.PublishDate.Value.Date || (dateFilter == DateTime.MinValue)
// is unread, showRead filter is on, or message was marked read today
where detail.IsRead == false || showRead || detail.ReadDate.Value.Date == DateTime.Today

group detail by detail.Message.MessageCategory into categories
orderby categories.Key.Name
select new
{
MessageCategory = categories.Key,
MessageDetails = categories.Select(d => d)
};
e.Result = messages;
}
This code *works*, but sticking a huge LINQ statement like this in the code-behind for a LinqDataSource control just doesn't sit right with me.
It seems like I'm still coding queries into the user interface, only now it's LINQ instead of SQL. However, I feel that building another layer between the L2S classes and the UI would cut back on some of the flexibility of LINQ. Isn't the whole point to reduce the amount of code you write to fetch data?
Is there some possible middle ground I'm not seeing, or am I just misunderstanding the way LINQ to SQL is supposed to be used? Advice would be greatly appreciated.

I would like to have child spans of the same width, independently of how many of them are there.
What I've done so far: added a "float: left;" style for every span and specified its percentage width (percents are more or less fine, as the server knows at the time of the page generation, how many menu items are there and could divide 100% by this number). This works, except for the case when we have a division remainder (like for 3 elements), in this case I have a one-pixel hole to the right of the parent div, and if I rounding the percents up, the last menu element is wrapped. I also don't really like style generation on the fly, but if there's no other solution, it's fine.
What else could I try?
It seems like this is a very common problem, however googling for "child elements of the same width" didn't help.

IE: I want to drag this vertical line (splitter bar) left and right (WEST and EAST).
Of the the system cursors (OCR_*), the only cursor that makes sense is the OCR_SIZEWE. Unfortunately, that is the big, awkward cursor the system uses when resizing a window. Instead, I am looking for the cursor that is about 20 pixels tall and around 3 or 4 pixel wide with two small arrows pointing left and right.
I can easily draw this and include it as a resource in my application but the cursor itself is so prevalent that I wanted to be sure it wasn't missing something.
For example: when you use the COM drag and drop mechanism (CLSID_DragDropHelper, IDropTarget, etc) you implicitly have access to the "drag" icon (little box under the pointer). I didn't see an explicit OCR_* constant for this guy ... so likewise, if I can't find this splitter cursor outright, I am wondering if it is part of a COM object or something else in the win32 lib. | c++ | winapi | native | null | null | null | open | Win32 HCURSOR

Really? No templates? Why? You got 16 gigabyte, im sure it's not that hard..
Ok so my question is either, can you inform me what I need and links to proper documentation for creating an app that will just let you store some sms templates and numbers and then with just a click or 3, send a transfer order.
Or, alternativly, can you build this and share it with me?

If somebody tries to save a new Job to the database using a JobName that is already in the database, MySQL throws a warning.
I would like to be able to detect this warning, just like an error, in my PHP script and deal with it appropriately. Ideally I would like to know what kind of warning MySQL has thrown so that I can branch the code to handle it.
Is this possible? If not, is it because MySQL doesn't have this ability, PHP doesn't have this ability, or both?
Thanks in advance.

Problem is that a bug occurred when an exception was thrown before Dispose was called, and the programmer neglected to use using or finally.
<rant><br/>
In C++, I never had to worry about this. The call to a class's destructor would be automatically inserted at the end of the object's scope. The only way to avoid that happening would be to use the new operator and hold the object behind a pointer, but that required extra work for the programmer isn't something they would do by accident, like forgetting to use using.
<br/></rant>
Is there anyway to for a using block to be automatically used in C#?
Many thanks.

Amongst other sections (which I may post here as I get to them) I am writing a section on code formatting. So to start with, I think it wise that, for whatever reason, we establish some basic, consistent code formatting/naming standards.
I've looked at roughly 10 projects written over the last 3 years from this team and I'm obviously finding a pretty wide range of styles. Contractors come in and out and at times, double the team size.
I am looking for a few suggestions for code formatting and naming standards that have really paid off ... but that can also really be justified. I think consistency and shared-patterns go a long way to making the code more maintainable ... but are there other things I ought to consider when defining said standards?
- How do you lineup parens? Do you follow the same paren guidelines when dealing with classes, methods, try catch blocks, switch statements, if else blocks etc.
- Do you line up fields on a column? Do you notate private variables with an underscore? Do you follow any naming conventions to make it easier to find particulars in a file? How do you order the members of your class?
What about suggestions for namespace, packaging or source code folder/organization standards? I tend to start with something like
<com|org|...>.<company>.<app>.<layer>.<function>.ClassName
and I'm curious to see if there are other more accepted practices that what I am accustomed to before I venture off dictating these standards.

For development (localhost), we might be running Tomcat and when declared in the <context> section of server.xml, Tomcat will hang JNDI datasources on "java:comp/env/jdbc/*" in the JNDI tree.
**Problem:** in Weblogic, the JNDI lookup is "appds" whilst in Tomcat, it seems that that I must provide the formal "java:comp/env/jdbc/appds". I'm afraid the Tomcat version is an implicit standard but unfortunately, I can't change Weblogic's config ... so that means we end up with two different spring config files (we're using spring 2.5) to facilitate the different environments.
Is there an elegant way to address this. Can I look JNDI names up directly in Tomcat? Can Spring take a name and look in both places? Google searches or suggestions would be great.
