When I create a document based on this template, Excel automatically names it TIP-PBI1. However, I want to give it a custom name.
I figured I could do that by modifying the .Title property of the Workbook. To that end, on startup the Workbook_Open event kicks off, and the following is executed:
Private Sub Workbook_Open()
Dim strPBI As String
strPBI = InputBox$("Enter PBI", "Enter PBI")
ThisWorkbook.Title = "TIP-PBI-" & strPBI
End Sub
However, this does nothing.
How can I change the Title of the document on startup?

How should a one man personal/free project get good controls when the suites all cost something like 2000$?!
I mean, there seem to be some nice free custom controls on codeplex such ass odyssey and wpf extended toolkit but when I look at viblend, dexexpress and telerik... How could I get such nice and powerful features for free?
They should all make a version for open source projects... I can't afford those, and without any of those my application looks so plain hehe.

I'm a newbie with a bit of PHP experience, currently I'm trying to learn C#. I brought two books from the shop Head First C# & Illustrated C# 2008, I have this thing for learning stuff visually, that's why these two books are on the top of my list.
But it turns out they're not as good as I thought, please please dont get mad if you're fan of these books, let me allow me to explain why at the end.
Here's few key things I'm looking for in the book:
**- provides practical exercises at end of each chapter.
- kinda 5W1H style, What/Why/When/Where/Which/How (if it's possible)
- gives a target project, build on bit by bit at each chapter (if it's possible)**
And here's my problem with these two books:
Illustrated C# 2008, excellent reference book, nice and clean, I really wanna to love it but it tells you all about the trees, but very little about the forest, and another problem I have is that for example, delegate is the concept I really dont understand, why would I use a delegate? Or when would I use a struct instead of a class? That being said, I still think this book is one of the best C# books out there, and for sure I'm gonna re-visit it later on.
HFC, before I got HFC, I've read Head First Programming...using Python, which is really good, I had such a great time with it, but HFC kinda let me down, maybe C# is too complex, too big for this kinda style? The pages are so cluttered with doodles and pictures and snippets of text and faux-handwriting and arrows that it's just plain hard to follow the conceptual thread of the instruction. | c# | books | null | null | null | 09/17/2011 22:32:50 | not constructive | Recommend C# books besides Head First C# & Illustrated C# 2008 for beginner

This is always followed by the conclusion that **only one alone element with this _#id_ can exist into the DOM tree**.
So if you need to use a CSS selector for a kind of element that has another occurrences into the DOM tree you have to use a _.class_ selector.
Well, I have serios doubts about this constriction also I think is not responding to a real need and avoiding a more intuitive use of the _#id_ and _.class_ selectors.
The question:
Existing the [chain selectors](http://www.w3.org/TR/CSS2/selector.html#descendant-selectors) like _'#id1 #id2'_ I could understand that _#id2_ better to be unique into the _#id1_ context, but **which is the meaning of forcing that _#id2_ should be unique into the whole DOM context?**
This rule is just fueling a degenerative hell of _id_ nonsense-naming. Also forcing us to over use the _class_ attribute.
I feel more confortable avoiding this rule and building structures like this, _(please understand that the code is simplified and not using concrete HTML structures in propose)_:
<div id="armys" class="list">
<div id="1" class="element">
<div id="orders" class="text">My orders</div>
<div id="soldiers" class="list">
<div id="1" class="element">

<div id="soldiers" class="list">
<div id="3" class="element">

without any explanation. I think it because the last two lines might be to short so I add this paragraph. An answer to this question would be nice two.

To affect all content, both subfolders and files, one should combine ContainerInherit and ObjectInherit according to the .NET documentation. But I can't get that to work and I'm not sure about the syntax.
Sample code:
$ar = new-object System.Security.AccessControl.FileSystemAccessRule(New-Object System.Security.Principal.NTAccount($user),FullControl,ContainerInherit,InheritOnly,Allow)
That'll work and so would using `ObjectInherit` only, but how can I combine them? Using quotation marks and a comma, like this `"ContainerInherit,ObjectInherit"` won't work, since it's appearantly not allowed to mix string and non-string argument.
I've also tried using the `-and` operator, but that just gives me an error. Assigning the enums to a variable (`$inherit = ContainerInherit,ObjectInherit`) won't work either.
So, any tips on how to do this?

I've also tried using the `-and` operator, but that just gives me an error. Assigning the enums to a variable (`$inherit = ContainerInherit,ObjectInherit`) won't work either.
So, any tips on how to do this?

I currently use the maven assembly plugin, but am fully willing to try something else as long as it can easily be integrated into a maven build process.
long: I use maven to manage different stages of development for my tool (basic stage is freeware, second has some more features, third stage is all features).
That works fine so far, I use profiles to add the different source directories to the classpath and the sources are neatly compiled into the project jar.
- Here is the first problem: The .java sources included into the project via the profiles end up in the project jar.
Then I use the maven assembly plugin to construct a single jar and in the end use launch4j to produce an executable for windows (the current target platform).
- Here is the second problem: The various META-INF parts from the dependency jars mix in the final jar and I would want them all to be skipped.
I have searched for examples of the assembly.xml using the exclude tag, but did not find any that used my combination of dependencySet and <exclude>*.java</exclude> (I'm not even positive that I can do that...).
Here is my assembly.xml: http://pastebin.com/dGwRMUBK
My research so far:
I have googled with "example assembly.xml exclude java" but could not find examples that covered my problem. (I have also googled a lot the past days but did not save all I found)
I have read http://maven.apache.org/plugins/maven-assembly-plugin/advanced-descriptor-topics.html but could not apply that knowledge to my problem.
So, thanks a lot in advance if you can point me to the right direction.
As said before, I am fully willing to use something different than the assembly plugin if it solves the problem :) If I can't find the answer I will most likely begin to write my own after-build shellscript to do what I want, but I would prefer not to.
Have a lot of fun

Each table would have an ID column with primary index and all table are 1:1 related.
It is a common problem within many data entry applications where we need to collect 1000+ data points. One solution would be to have one big table with 1000+ columns and the alternative would be to split them into multiple tables and join them when it is necessary.
So perhaps more real question would be how 30 tables (30 columns each) would behave with multitable join.
500K-1M rows should be the expected size of the tables.
Cheers

The following block only exists as C# syntactic sugar to enforce an extra layer of variable scope in the source code.

My problem is that I have a hard time starting problems out for when we get assigned projects to do. Other classmates seems to take everything the professor said once from a lecture, and can take that to every little end point and memorize it in a flash. Myself on the otherhand, even after vigerous notes, and multiple times looking over the material, still struggle on figuring out what to do to start different problems, or procede at times when I am stuck. Sadly enough though, I can remember random details about anything else, or look over other things one time over, and be in that same situation of knowledge. Now, Im not looking for the general, "practice, practice, practice' answer, but more if anyone any tips/tricks they used to help remember things during the coding process. Would greatly appriciate it to hear everyone's comments.

For that,as Swanny told me to go through a link http://www.cake-toppings.com/tag/subdomains/ and I did it on my application as it was said on the link.Apparently,it worked for login which shared session between two domains(main domain and it's subdomain).But when I checked it thourogly,i recognized that both the sites are throwing the latest NEWS from Database,both data are different.Just to check if I was wrong I changed the some save variable to database in session array.But now it refused to remember anything(session).Could anyone suggest me what could be problem with this and how can I resolve this...???

===
Well as I have posted earlier too...I have created a site in two languages.One with URL www.mainDomain.com(English) and other with www.fr.subDomain.com(French).Both are done in CakePHP,in french I have just changed the views of it to French.But the problem is,when anybody login's in English version and then switches to the French version,the session does'nt recognizes it and ask for login again.It has become to be the biggest bug in the Web application which I have done till far.

I limit the names to only certain characters, but last names are a challenge. Since some people have single quotes in their name (example O'Brian) I need to allow this. So I wrote a regex replace to replace the ' with a \' which I assumed should make the ' a literal. It works as far as replacement goes, but it still marks the end of the string, and I get the error
There was an error parsing the query. [ Token line number=1, token line offeset = 71, token in error=Brian]
I understand the error, the single quote marks the end of the string to be entered leaving the rest of the string Brian outside the quotes.
The code I am using:
Regex reg = new Regex("\'");
firstName = reg.Replace(firstName, "\\'");
lastName = reg.Replace(lastName, "\\'"):
Then the select query is built with string.format
sqlInsertObj.CommandText = string.Format("INSERT INTO childNameId (childFName, childLName) VALUES ('{0}', '{1}')", fName, lName);
sqlInsertObj.ExecuteNonQuery();
This works for any entry, except when there is a quote in the name.
