Go away Murphy's Law! About a minute ago I figured out how to get sub_directories.
Thanks.

Hi All
Is declaring a Variable using static public int aVariable = 0; the same as using public static int aVariable = 0;
and if not why is this so.
Equally if they are are the same why the two formats.  
Thanks

There's no difference. It's not really two formats. In the specification of the language, there are just no rules regarding the order that you can specify certain combinations of modifiers/accessors.

These are the same; both of these statements define the following portions of the field declaration:
[modifier] [accessibility] [data type] [variable name] and [initializer]
The static keyword is the modifier, which identifies exactly one storage location.
The public keyword is the accessibility, which defines the external visibility of the field.
The int is the datatype.
The language specification doesn't require a specific order for the modifier and the accessability keywords, as long as they come before the datatype the compiler will understand what is meant.
This lack of order for these keywords is done mainly to leave the order up to individual preference. Some people prefer the accessibility to be stated first, while others prefer the modifier first.

I have an application in C# who is connected with access database.
I have table called tblStudent. My problem is:
Can I pick a value of combobox, and all data for that value
to get in CrystalReports...
Table tblStudent has a first field number called IDStudent
I mean when I select from combobox for exapmle
value 23(this is IDStudent number for 23-trd student), I want crystal reports to take all data
with value who I choosed from combobox.
If I choose from combobox value 15, the crystalReport to take
all data for student with IDStudent 15.
Is this possible? I try to resolve this, but I am beginner
so I need your help C# lovers.
Thank you veru much, and I apologize for
my bad english in some parts of the text.
Greetings

Hi,
I have some advanced knowledge of programming with C and C++.
While I like C for its simplicity and speed, it lacks some important functionality (like OO). I'm not very fond of C++, since it is quite clumsy. (But you know all that already)
Anyway, I was looking for a new programming language for little projects. I looked into the specs of the D language and became quite fond of it. Anyway, I hear a lot of good things about C# as well.
I am not experienced enough to compare the two simply on the basis of their specifications. I tried finding some comparison on the internet but failed to find anything more recent than from 2003.
I was wondering about the advantages of either and languages, and in which case one is more appropriate than the other and I hope you can help me out!
Many thanks in advance,
Mike

C++ is awesome, sorry to disagree.
The main advantage of C# is that more than 5 people have heard of it, there's tons of support and there's actual real world jobs using it.

At the end of the day, if you want performance, you want C++. However, realistically, the fact is that for most tasks, you won't notice the difference that C++ gives you. If you just want to program for fun, then the answer is, a forum dedicated to the D language is far more likely to contain people who have used C# than vice versa. Even then, I don't see it as likely that you'll have reasons to use D that are compelling enough to offset the lack of support.
If you have any intention of coding for a living, then you can't avoid the fact that C# is where the money is at ( unless there's a niche market for D that I'm not aware of ).

I looked at D a few years back, and as far as I'm concerned it's C++ with added sugar (and garbage collection). Neither language fixes all the shortcomings of C.
On the other hand, when considering C# it's not so much a question of the language itself, because C# targets the .net framework which, for me, far outweighs any particular language features and really invalidates any comparison.
I use C# regardless of the size of the project, though I still use C a little bit as well.

Hello, I have a multiple textboxes in a form.
I read in values from a textbox, and depending on what is read in, values are sent to certain textboxes. However I am not able to do this dynamically.
---textfile---
ownerFields_text
--------------
private void writeToApp(string readIn)
{
TextBox txtBox = new TextBox();
txtBox.Name = readIn;
txtBox.Text = "Why wont this work"; //line doesnt work ownerFields_text.Text = "hello"; //line works
}
Although looking in the properties in the debug windows for txtBox,shows property name=ownerFields_text, but its just not printing "Why wont this work". I do not want or cant cycle through controls for the right one.
Thanks.

So you create a new TextBox, give it a name and some text.
Fine.
This has nothing to do with other TextBoxes that may already exist.
It will not magically point to an existing TextBox with the selected name!
If you want to set the text of MyFirstTextBox, the one direct way to do this is
by MyFirstTextBox.Text="new text";
If you want to modify one of many existing Controls, you either need:
1. a lot of code (one piece for each Control), say a switch
2. or a Dictionary that maps names onto Controls
3. or Reflection

You are creating a new control that isn't displayed anywhere. Giving it the same name as another control doesn't automatically transform your new control into that control. They are still separate objects.

If you don't have a reference to the control, you have to. You can use the Find method to do it for you.

Hi,
I am currently developing some application which have a lot of controls on them, especially an explorer bar which when the application window appears, is actually empty and white for a few seconds and then it is populated.
I am wanting to know if it possible and how I would implement a splash screen that is shown and updates a status label on the splash form, which stays until all the controls on my mainForm have been drawn and populated.
I am programming in C# in the MS Visual Studio 2005 (Vista) environment.
Thanks, Andrew Robinson.

Hi Andrew,
a splash screen is a popular topic, I suggest you search CodeProject for
some highly rated articles about it.

In fact, NONE of the splash screen components/classes I saw for .NET were of any use to me.
And I search a lot and found a lot...

|

Really? Maybe you should write an article about the subject then...

No chance - I have no clue either; otherwise I wouldn'T have searched

I thought there was a splash screen component built in, but a splash screen is just a form. Use the Show method so that it doesn't stop the rest of your app from running.

Hi,
I am using a lot of controls on my main form, and require the splash screen to be shown until all the controls are drawn. I am using the AppLoader Quick n Dirty in C#. I have the splash working but don't know how to make it stay until the main form has completed loading and populating a control.
Any help is appreciated.
Thanks, Andrew.

Hi, maybe you should use the Activated-Event of the main form. This event occurs when the form has completed loading!
