Thanks to all the replies.

I know why this takes place. The OffsetX / OffsetY in the matrix has been changed.

Have a good day, gentlemen.

First. Please the the code block formatting. It preserves your indents to make the code readable.

I am drafting a control which can zoom the image and scroll. But unfortunately, the background will erase the image. I do not know why.

Second, you appear to be misinformed about what PaintBackground does. It repaints the background of the entire control, including any areas which you have previously drawn a foreground object. If you wish to preserve them, any forground objects must be repainted after the PaintBackground call.

.swf isn't supported by windows media player and the .net media player classes share a common core with it.

I believe there's a flash playing COM object that gets installed with flash player automatically. You'll have to add a reference to it in your project and use it to play the file.

According to the documentation[^] this event will only be raised if Firebird issues a warning message.

Are you expecting a warning message from the database?

What do you mean by a "knowledge message"?

muhammedmustafa wrote:

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 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 Wink | ;)

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)
{
// set values here
}
}

List<valuesholder> ValuesHolder_List = new List<valuesholder>();
ValuesHolder_List.Add(new ValuesHolde(id, parentID, text)); // an example



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--); // delete that item as well as a step back
   }
}

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--); // delete that item as well as a step back
      }
   }
}

I didn't test the code, but I'm sure it'll help you.

Adding my app's link to Desktop Context Menu

Sumit Prakash Sharma10-Apr-09 1:06

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:

// create 2 registry entries to get an entry in the Explorer context menu for all files and folders:
// (replace AllFilesystemObjects by * for files not folders)
// HKEY_CLASSES_ROOT\AllFilesystemObjects\Shell\appname.ContextMenu:
//		(Default) Open using myApp
// HKEY_CLASSES_ROOT\AllFilesystemObjects\Shell\appname.ContextMenu\Command:
//		(Default) apppath "%1"

you would need admin privileges to do this.

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.

Call event in another event

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 Smile | :)

.

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)
{
   //do some stuff

   //do some stuff the same as button2
   Button2_Clicked(sender, e);
}

public void Button2_Clicked(object sender, EventArgs e)
{
   //do some stuff
}

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)
{
   //do some stuff

   //do some stuff the same as button2
   doStuffFromButton2();
}

public void Button2_Clicked(object sender, EventArgs e)
{
   //do some stuff
   doStuffFromButton2();
}

public void doStuffFromButton2()
{
   //do some stuff
}

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)
{
// No exception caught!
}

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.
