I have this problem:
I want the "user" to be able to set properties for the forms in my application in a settings window. The problem is that i want to populate a treeview with all the forms in the application. All of theese forms has probably not been activated when the user opens the settings dialog. How can i loop trough all forms in the application and populate a treeview with them? So far i only managed get those that have been created (with the obvious "foreach(Form form in this.mdichildren)".
So if somebody could help me with this it would be appriciated.

hi guyz.How do i do this.plz help!!!
Create a client/server application for the game Hangman, using stream socket connections. The server should randomly choose a word or phrase from a text file. After connecting, the client should be allowed to begin guessing. If a client guesses incorrectly five times, the game is over. Display underscores for the letters that have not been guessed yet, and display the letters that have been guessed in the word or phrase on the client.

I am trying to connect to a sybase database. Can someone tell me what the easiest way would be to accomplish this and where can i download sybase drivers for .net from ?

Hi,
I think the easiest way to do this is to use the ODBC interface. Just set up a new Odbc Connection using the Data Provider Dialog from Windows (Control Panel -> Administrative Tools -> DataSources), and then connect to this ODBC entry using the System.Data.Odbc namespace. If you need any further help, please let me know.
Regards
Sebastian

there is no sybase driver to select from. anyone have a clue where i can find one ?
|

Normally this driver should be installed with your Sybase installation. Maybe you should install the client software to get the ODBC driver.
If not you have to do it the hard way and search this driver in the net.

Do Sybase not provide a .NET managed provider?

Hi all,
Can anyone help me out with this:
in my datagrid's ItemDataBound event, I want the method to do something like this:
private void onItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if (e.Item? or e.Item.Cells[0].Controls[0]??? == a CheckBox object)
// then do stuff
else
// do nothing
}
any ideas?
|

Hi,
I think there are two possibilities to do that:
1) if(e.Item.Cells[0].Controls[0] is System.Web.UI.WebControls.CheckBox) { // do something }
2) if(e.Item.Cells[0].Controls[0].GetType().Equals(typeof(System.Web.UI.WebControls.CheckBox))) { // do something }
I don't know if the first one is correct, I always use the second possibility. But be sure to test if there is a cell or control and that it is not null before you use the GetType() method (otherwise there will be a NullReferenceException).
Regards
Sebastian

I have something like this:
string a=string.Empty;
if(b!=a){}
from this i can check if b is a empty variable for the condition of the if loop.
there isn't any int.Empty, how can i do the same if i want to compare if a int variable in empty for a if loop?

An int when declared is initialised to 0 if i am not wrong, or just rubbish value. Either way, they can't be "empty".

The property string.Empty is just a static string with the value "".
string a = string.Empty;
has the same effect as:
string a = "";
The only difference is that the second one creates a new string object, while the first one uses the empty string that already exists.
As there is no gain in having static instances of value types, there isn't any static zero constant. Just use the value zero:
int a = 0;
---
b { font-weight: normal; }

hi
i have some experience in c++ and vc++
i want to migrate to .net
would u tell me which language should i learn first for .net??
ive heard that c# is the mother of .Net .so i should learn c# first or go directly to visual c++.net??
and also i awnt to learn asp.net what should i do?
thx

The is no difinitive answer to that question.
I work with c# because my background experience is in Java, and the similarities made it easy to migrate from Java to c#. Also most of the readily available books on writing Windows apps. and asp.net web form's are orientated around c# and VB, although i'm sure it is easy to get hold of books orientated around c++.
The beauty of Visual Studio.net is that all the language's have more or less the same level of functionality.

Out of curiosity, what reasons did you have for trying .NET? Does .NET provide anything significant over what the Java frameworks do?

Well to tell u the truth the only reason I took up .Net is I am currently an intern in Microsoft Ireland. But there are so many advantages...
The excellent help section that comes with Visual Studio and online, not to mention the code samples.
The Microsoft press release contains tonnes of book for helping developers do just about anything.
You have to pop-up menus that appear each time you use dot notation, telling you what methods are available to you.
I always wanted to learn to use ASP.NET and with talking to people here at MS Ireland, c# or VB are the languages of choice for ASP.NET applications. Since c# is similar to Java, I chose it over the other languages. I picked it up quite easily, and i've never been a fan of VB, the syntax annoys me for some reason.

Don't you get similar help and samples with Java?

Hello
It all depends upon the kind of Background u come from, by that i mean which language you are well versed with. Since you have been using C++ and vc++ earlier it would make things easier for you if u go for VC++.net.
As for C# it's Language worth learning and easy to pick up too.
best of luck!!!

I have a class to which I can pass any SQL query and it can return “DataReader” object or “DataSet” etc. To achieve this I have different methods in that class.
What is the best way to use database connection in ASP.NET application? I would like to use connection pooling too. Database is SQL Server 2000. Should we use singleton class in this, if yes, how can we use?
I appreciate your help.

Connection pooling in ASP.NET happens all by itself, you can just create connections as you need them, I believe.
