Now, I just recently found out about PropertyGrid and I think I like it.
My problem is, I can't figure out how to display my tree in a apropriate way.
My classes look like this:
class MyTreeNode
{
List mylist = new List();
public MyTreeNode[] SubNodes
{
get { return (MyTreeNode[])mylist.ToArray(); }
}
public string Name = "something";
}
I want this MyTreeNode class to display as a list of nodes; but instead of that [0] as a name it should display the node's Name-attribute. I would also like to set the value to something different.
I just can't figure out how to do that exactly.
please give me a hint.
so long.

Hi,
I don't know if this works, but what about overriding the ToString() method. This overridden method should return the name. Maybe this will display the name attribute.

If we use System.Data.OracleClient namespace in desktop application, do we have to have Oracle client installed on the machine/desktop to access database.

Yes, version 8.1.7 or later.
Here[^] is a link to the pertinent documentation.

Is it possible to access Oracle Database without having Oracle client installtion?

As far as I know (and speaking about Oracle, it's not very far), no, there isn't. You need the client.

I'm having a few issues with multiple projects going to the same output folder, particularly around the locking of 3rd party asssemblies that multiple projects reference, and the fact thast it can not be copied due to it being locked in the output folder by the IDE.
The main output is a windows service, that hosts remotable objects, and as no reference exists between the service, and the objects, i need some way to copy them to the output folder, so hello Post Build Step.
Now, if i copy all the files from the specific output folder, doing a *.*, i still get the same problem with locking on the 3rd party dll, (log4Net).
If i just copy the ${target}, then i do not get the dependant files that this project requires.
What is the preferred thing to do in this situation? Manually specifying the list of all the files to copy for each project, will be quite a laborius task.
Thanks

You might consider placing your third party assemblies in the common folder and just leaving them there, since multiple projects will reference them anyway, then just move the ${target} assembly into the common folder post-build.
If you apply the post-build script consistently to all of the projects in the applications whose assemblies you want in the common folder, you should be okay.

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.

Second - If so then u just need to implement a randon string choosing code at the infinite receive code in server to scan client messages and compare with the string u have ....

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 ?
TX
|
|

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.

Hi guys,
another datagrid help... how can i tell a method in javascript
coming from the ItemDataBound event that if this header item is checked (checkbox item) then select everything in the datagrid...
basically, how do i iterate through all of the checkboxes in the datagrid's column since i dont really know how to access my server side objects from the client side javascript
???

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".
