Search for "Control.DataBindings Property" in your vs.net help or msdn.
I think that's what you are looking for.

Search for "Array.Initialize Method" in your vs.net help or msdn too.
Mostly you don't need to call this method. For example you have an array of string, the compiler sets all strings inside this array automatically to an empty string.....

222
333
Rather than.

Thanks, this is easy, but I forgot what the sort code was, I think that it was like &ensp or something. Thanks.

\r\n should do it.
111\r\n222\r\n333

As the two posters above me replied, you can use "\r\n" or Environment.NewLine. The latter option is the recommended one though. It'll work depending on the platform you're running on, for eg. Unix's newline character is only "\n".

After creating an application in C# that runs fine on my computer and another developer's computer, we included it in an InstallShield project. When we try to run it we see the message box saying:
Common Languge Runtime Debugging Services
Application has generated an exception that could not be handled.
Process id=0xb3c(2876), Thread=0xb40(2880)
Click OK to terminate the application.
Click CANCEL to debug the application.
I've created a Release version but that didn't seem to matter. We have another program that's written in .NET that works fine. I've seen many postings on this error on the net but no solutions. Any ideas?

The most common thik of an error msg like this listed below (as I know):
- framework not installed
- some require component not installed/registered
So if you use a dll or ocx you must register it, in the other machine too.
eg.:
from command line:
regsvr32 mycomponent.ocx
or
regsvr32 mycomponent.dll

Actually you are close, we figured it out. My program is using an Access database via a datasource connection. When the program begins to load, it attempts to connect to the datasource. Unfortunately the connection path is hardcoded and the installation computer did not have the same directory structure. So when the program started it could not find it's datasource. We changed the path and moved the database to the right directory and it worked.
Ahhhh engineering!

Use a RichTextBox.

Owner draw. Which also applies to a TextBox, if you don't want to go the RTF route.

Hi im programming with the enterprise library, where can i find help for it? some guides for programming dataconections, dataaccess...thanks
|
|

There's about 10 MB of documentation and quick starts that come with the distribution. Look for the "Docs" and "QuickStarts" directories sitting under where you installed it.
You can find info on the official site[^, as well as a group of webcasts[^] that are pretty informative, if you don't mind the rather jovial tone of most of the sessions.
There are also links to more information on Channel9[^].
There is no shortage of information about the Enterprise Library. All you have to do is look for it. Google is your friend.

I've made an interface in C# in which is it possible to load multiple images in pictureboxes. The problem is that the boxes are not transparent.
When the pictureboxes are overlapping, there is a white square around it.
Does anyone know how to solve this problem?

how do i select the whole row in datagrid when clicking on single cell without selecting text in it
|
|
|
|
|
hey you want to do it in client side or server side.
If you want in client side,you can add the JaveScript function to each item of the DataGrid in Item created event.
For Server side use select button.
But client sied will be very easy and fast.
If you want code stuff for that ask me i will send it to you
Tnx

I need to keep informations in memory, so i am using System.Collections - ArrayList, my structure is a Father and Son and grandson, where each Father can have any Son and each Son can have any grandson .
Father and Son and grandson are Arraylist, is there any problem adding then in each other ?
this structure is a tree, is there another to do this ?
ArrayList father = new ArrayList();
ArrayList son = new ArrayList();
ArrayList grandson = new ArrayList();
grandson.Add("joão");
grandson.Add("MAx"):
grandson.Add("Junior"):
son.Add(grandson);
father.Add(son);
thanks

Why not a class for each, which carries an arraylist of it's children and one of it's parents ? Ideally, you could give each person an ID, and store the names in a single hashtable by ID, so you can look up names when you need them, but the classes just carry an array of numbers ( nice and efficient, each name is only stored once ).
Then you could have a single arraylist of person objects, each of which has it's own ID, and the ID's of it's relatives. Of course, I'm not sure how this would suit you in terms of your searching needs.
So
Person bob = new Person("Bob");
Person fred = new Person("Fred");
Person Bill = new Person("Bill");
Inside the person class:
ArrayList myChildren = new ArrayList();
static Hashtable Names = new Hashtable();
static int IDs = 0;
Inside the constructor:
this.ID = IDs++;
Person.Names[this.ID] = name;
Then a method to add a child:
public int AddChild(Person child)
{
myChildren.Add(child.ID);
return myChildren.Count;
}
You could either add grandchildren with a method, or implicitly ( have a GetGrandchildren method that works out who the children of my children are ).
