What do you mean by a "knowledge message"?
muhammedmustafa wrote: i do not want a fail message from database
Nobody does. But the simple fact is that failures do occur and you have to be able to handle them gracefully when it happens.
The event you are handling is, according to the documentation, only used when an error of some description happens. If you have success the event won't need to be handled as there is no failure to deal with.

No never. It seems to me that I'm just reading the documentation on your behalf.

You mention a Web App and JavaScript. You are aware that this is the C# forum, right?

You can see the relation between Cate and MC
The child node’s MC = Cate of Parent Node. I am finding problem to construct treeview in visual studio 2005 and C#.Net window application.
The Main Problem is :
1) How can we count the parent , child and grandchild node by firing query?
2) How can we add childnode at exact below its correct parent node?
3) How can we display the information in Listview from table for selected node?
Please help me on this topic and get bless from god! My project has to be completed in next 2 days. Please help me! Thanx In advance!

I wrote a code for this a month ago but now I do not remember it correctly. However, I'll try to explain 
All you need a funtion and a generic list to hold all these values. eg.
public class ValuesHolder
{
public int ID;
public int ParentID;
public string Text;
public ValuesHolde(int id, int parentID, string text)
{
}
}
List<valuesholder> ValuesHolder_List = new List<valuesholder>();
ValuesHolder_List.Add(new ValuesHolde(id, parentID, text));
for (int a = 0; a < ValuesHolder_List.Count; a++)
{
if (ValuesHolder_List[a].ParentID == 0)
{
TV.Nodes.Add(ValuesHolder_List[a].ID, ValuesHolder_List[a].Text);
ValuesHolder_List.RemoveAt(a--);
}
}
while (ValuesHolder_List.Count != 0)
{
for (int a = 0; a < ValuesHolder_List.Count; a++)
{
TreeNode[] tns = TV.Nodes.Find(ValuesHolder_List[a].ParentID, true);
if (tns.Length > 0)
{
tns[0].Nodes.Add(ValuesHolder_List[a].ID, ValuesHolder_List[a].Text);
ValuesHolder_List.RemoveAt(a--);
}
}
}
I didn't test the code, but I'm sure it'll help you.

They can't. They have to authenticate themselves as a user with sufficient privileges.

When you right click on the desktop you get a context menu that has something like that:
-----------------------
Arrange Icons By
Refresh
-----------------------
Paste
Paste Shortcut
-----------------------
New
-----------------------
Properties
-----------------------
I need to add a link to my application on Desktop's context menu. How can I accomplish that? What registry key do I need to modify/add to get my app icon listed on the desktop context menu?
E.g.:
---------------------------
Arrange Icons By >
Refresh
---------------------------
My App Link >
Paste
Paste Shortcut
---------------------------
New
---------------------------
Properties
---------------------------
Please help. Thanks.

Hi,
There are several ways to do it, here is one using the RegistryKey classes:
you would need admin privileges to do this.

i am already know this that. but i want to know how to add shortcut on desktop context menu, so that whenever user perform right click on desktop, my application's shortcut should be visible. please help me
|

|

I am unaware of a registry key supporting the desktop context menu.
There must be ways to do it programmatically, sending some Windows messages to the desktop Window,
it is a simple ListView after all. However I don't know any details, never saw it, never needed it.

Hi,
How can I call one event in another event, like I want to call form click event into form load.
what should i do for this issue.
Please do replay
|
|
|
|
|
You can replay a cd, not a post .
But to call events like you would like, you have to call it just like a function:
public void Button1_Clicked(object sender, EventArgs e)
{
Button2_Clicked(sender, e);
}
public void Button2_Clicked(object sender, EventArgs e)
{
}
To be honest: this is not really neat.
To make it more beautifull, you should just make a function like this:
public void Button1_Clicked(object sender, EventArgs e)
{
doStuffFromButton2();
}
public void Button2_Clicked(object sender, EventArgs e)
{
doStuffFromButton2();
}
public void doStuffFromButton2()
{
}

oh.... tested:
* ODP.NET version 2.111.6.20
* Oracle 11g
* .NET 3.5
try {
...
using (oScope = new TransactionScope(TransactionScopeOption.Required, TimeSpan.FromSeconds(60)))
{
...
DoFirstDatabaseOperation(...); << Application just exited!! No exception!
...
} catch(Exception ex)
{
}
I enabled ODP.NET tracing by adding to app.config:
<br />
<oracle.dataaccess.client><br />
<settings><br />
<add name="TraceFileName" value="c:\odpnet1.trc"/><br />
<add name="TraceLevel" value="63"/><br />
</settings><br />
</oracle.dataaccess.client><br />
It looks like we've a "System.AccessViolationException" while "Oracle.DataAccess.Client.ConnectionDispenser.CreateConnectionPool" is invoked. ODP.NET assigned to it the following error code:
"ODP error code=-3000; ODP message=Data provider internal error"
Help anyone? I been haunted by this last few days and looks like it will continue and ruin my Easter holiday.

Then I would suggest that it is too complicated, for a first project.
It is a well established fact that all first projects, regardless of the technology/language being used, MUST be a 'Hello World!' app. 
You might also consider that one of the CP fora that deals with Webby things, might get you a better answer than this one.

If you are using VS2008 and .net 3.5 you can use the System.Management namespace. Have a look at this link.
