I am trying to develop a windows application allowing user to control windows services. I have an ArrayList containing windows services data to be displayed to the user. Except displaying the Service Name and status, I would like to have a column of check box and maybe a column of buttons associated with each row.
I am not sure whether to use Listview or datagrid? and it seems none of them support column of button control?
Can anyone give me some advice on this?
Thank u very much!!

Hi!
If you want to use a ListView you could take this approach:Embedding Controls in a ListView[^] to "fake" your buttons into the ListView.
Checkboxes can be enabled for the ListView as well, so I think this could work pretty well.
Can't tell you much about the DataGrid, though... 
Regards,

I have this CheckBox Column (DatagridBooleanColumn), i need this to get True/False input from the user, the problem is that at the end of the columns, i can somehow add new rows, How can I make my datagrid Editable but will not alow the user to add new rows when clicking at the bottom, thanks

Hi gentleman,
I am going to establish a connection to SQL server or MSDE and during that I want to show the user a progressbar to view the wasted time.
I tried different Windows timers in the same class (form timer) or system timer with callback function etc. to let the progressbar run but when I sending the connection command the timer stops until connection timeout event rises or connection establishes.
Is there an other way but using a thread to let the timer tick.
Why do the timer not running independant or is there a one I don't know.
Thank you for you inspiration

My datagrid is bound to a database table. One of the table has the web addresses like , www.amazon.com etc etc. I want the users to display the hyperlink in the datagrid and not the value, so that the users can click on the hyperlink and go to the web address.
Thanks for the help.

Is this for the System.Web.UI.WebControls.DataGrid or System.Windows.Forms.DataGrid? If it's the former, 1) there already is a column type for that (HyperLinkColumn), and 2) your question belongs in the ASP.NET forum.
If it's the latter than you'll need to implement your own DataGridColumnStyle derivative class and add that to a DataGridTableStyle for your DataGrid. Read the documentation[^] for the DataGridTableStyle class to see how it's used with the DataGrid.TableStyles property. This explicitly defines a style (i.e., columns, their header text, width, etc.) which lets you add columns of a specific type.
See the documentation[^] for the DataGridColumnStyle for information - and an example using a DateTimePicker control - about implementing the class. There's also a few articles here on Code Project if you search for "DataGridColumnStyle", but, IMO, you'll find a better example in the .NET Framework SDK.

1. Don't assume people know everything. I've never heard of go!fish. Describe the rules of the game.
2. Post this in the correct forum. This is the C# forum. I suggest you try the Visual C++ forum.

Hello, was wondering does the ArrayList has a way to determine the validity of the item (at compile time) to be placed into the container like C++ template? I know the type that the ArrayList could accept is object (which is everyone) but what if I need to be just integer instead?
Anyway?
thanks

What Corinna was saying about .NET 2.0 would be the List<> class. You can use that like so:
List<int> ints = new List<int>();
ints.Add(1);
ints.Add(2);
ints.Add("blah"); Besides using a generating you can currently extend CollectionBase, which uses an ArrayList internally. You define your methods to be typed according to the Type you want to accept.
Using this is a good way to produce more portable code. If you extend CollectionBase now, you can easily extend List<> later and just remove your CollectionBase overrides:
public class IntList : CollectionBase
{
public int Add(int value)
{
return List.Add(value);
}
public void DoSomething()
{
}
}
public class IntList : List<int>
{
public void DoSomething()
{
}
}See how easy that can be? Without changing your code that uses IntList you can change the base type and avoid boxing (since casting or treating a value type like int as a reference type object requires boxing).

Hello, I have just acquainted myself with C# and .NET and I have a question. I see there are some C# classes that represent Crystal report files and report interfaces (*.rpt and *.xsd) and I want to find out how do these classes work.
Thank you.
|
|

.xsd is an XML schema file, first of all. You can use these to define fields for a report that you can later bind to a DataSet (disconnected recordset) using ReportDocument.SetDataSource.
Using Crystal Reports for Visual Studio .NET is documented in the product documentation. Read Crystal Reports[^] in MSDN online for more information.

Hi! All,
please help me to create Dynamic Cursor files at run time.
|
|
|
|
|
This request is well beyond the scope of this forum about writing in and using C#. If you want to create cursor files at runtime you need to understand the structure of a cursor blob (data), which is documented in the Platform SDK.
Read about Resources[^] in MSDN Online for information about the cursor data structures.
If you need help declaring such structures in C# and serializing them to a file stream, first read Marshaling Data with Platform Invoke[^] in the .NET Framework SDK. If you have further questions about how to do this in C# - if indeed you're trying to do this in C# - you can ask here.

I want to get the selected text in an opened browser window programmatically from another winodw application that I created. I've to use SenKeys.SendWait("^C") function But it didn't solve my problem.
Or
I've created a object for a toolbar with some button.
That toolbar is added to InternetExplorer I want to select some text
from any page opened in the browser then click on that button to pass the
selected text from the page to the clipboard. So, I though to access
CTRL+C programmatically and I did using SenKeys.SendWait("^C") . But it didn't copy the selected text, I thought it loose focus from the area of
the page. so I tried to get refence to that area from the browser like
using
this.FindForm()
this.Parent
this.TopLevelControl
this referes to my button or the toolbar control that contains that
button.
I want o use:
bowserWindow.Focus()
SenKeys.SendWait("^C")
but all the trials to get reference to browser window returns null. I
tried to get refrence to the IEXPLOR process and succeeded and from it
got the handler of the window but couldn't cast it to a window.
Summary: I want to copy the selected text from body of the broswer page
programmatically from the toolbar button action or from another application

The best, most practical way of doing this is just accessing the DOM (document object model) for the body. Reference the Microsoft.mshtml.dll assembly in your project and add using mshtml; to the top of your source to import the namespace.
Cast the AxWebBrowser.Document property to IHTMLDocument2, which defines the body property. From that you can get either the innerHTML or innerText. If this seems familiar in terms of web development with DHTML, it's because you're walking the same DOM that script uses that is exposed by MSHTML, the HTML parser and renderer for the WebBrowser control (which is actually IE, not just iexplore.exe):
IHTMLDocument2 doc = (IHTMLDocument2)axWebBrowser21.Document;
if (doc != null)
{
IHTMLElement body = doc.body;
if (body != null)
bodyText = body.innerText;
}Hosting the WebBrowser control or MSHTML itself and accessing the DOM is what most clients do, and it allows you to access the full HTML DOM that script can.

Actually, I can't get access to the instance of the current opened browser window. I'm not using WebBrowser control. So, how can I got that refrence you refered to as
AxWebBrowser.Document

I am writing a program that requires array types and dimensions be decided at runtime. I can use System.Array.CreateInstance() to do this. What is the most efficient way to access the data in this array? I know I can use the getValue and setValue methods. I can also use the enumerable interface when allowed by the situation. Both of these are however inconvenient when compared to indexing the values using [].
Does anyone have any suggestions. Efficiency of the code is a major consideration.
Thanks,
Karl

If you expect the modify the array while enumerating you cannot use IEnumerable. It will throw an exception if the underlying enumerable changes.
Why not just use an ArrayList? It has the same read performance as an array because it uses an array internally. It's only when you add elements past the current capacity that there is overhead since a new array is created (doubling in size) and previous elements are copied.
Dynamic code is often an inconvenience, but there's not much you can do short of wrapping such behavior (which, once again, ArrayList already does for you - just examine the IL for yourself or use a decompiler like .NET Reflector). Ever written native code to access automation (IDispatch implementations) servers? It's a pain compared to automation clients like VB6 and script, but that's the price to pay for late-binding code.
