Take a look at the Dockpanel Suite[^] on SourceForge. It's quite good. If your application is meant for the average user though (as opposed to the average developer) I would reconsider using these kinds of controls, as they often find the VS way of doing things overly complex.
Standards are great! Everybody should have one!

You will need to install, installshield setup creator software. One you are done with this, you may use install shield to create a setup for it.
You may also check its help file for getting steps to use it.

Hello Sir/Mam,
I want to synchronise 2 images.when I perform operations like zooming ,panning on one image the other should get effected automatically. I have performed this in the following way......
In the mouse wheel event i am performing zooming. and mouse down and mousemove events i am performing panning.I am not using any scroll bars...
The problem is when i'm performing zooming(i.e., when i'm rotating the mouse wheel fastly then the images are not synchronised properly..I should overcome this problem.. pls help me..
Thanks,
rekha.

Well, I'd love to help, but seeing as you didn't post any code, I have no idea what you did wrong.
You should be storing the zoom for both images in one variable, so it's in sync

I assume you realise that this code is auto generated. I kind of meant just the pertinent code that you actually wrote.

actually we have posted every thing,that is why you confused , and you can observe the remaining things
in user control, and form code.
Thank you for your quick response.

I know what you did, I was asking why you couldn't take the time to create a post where I didn't have to read two huge posts looking for the little bits that are pertinent to the problem.

So that, I want to coding procedure or function with C# to refresh datatabase name.
Who can help me?
If posible I thanks so much.
For example:

one DGV is defined at runtime as show the other one is defined empty at design time the first does not fill the second yes
What can be the cause ?
DataGridView tmpDGV = new DataGridView();<br />
<br />

???, your question isnt proper, however if you wanna add DGV at runtime, then you will need to add it in the form else it wont show up
code to add control in form :
this.Controls.Add(tmpDGV);

Hello
One little thing : my intent was not tho show the DGV but to fill it with a datasource to print it with another control
Anyway the problem is the same : if the DGV is not added to the form, the Datasource has no effect.
Thank you

Hi! I have a data table called maps that had been bind to a list view. I would like to add an event to the list view that is onSelectionChange. Inside this event, when user make a new selection I will display the selected data out into a detail view. Does anyone know how to do this by using listview.SelectedValue? I am building whole thing in wpf and c#. Thanks for your help.
I had try out this code but it always return -1.
DataView view = new DataView(maps);
view.Sort = "mapTitle";
MessageBox.Show(view.Find(mapListView.SelectedValue).ToString());

Hi,
you have to register for event and create method that will handle that event.
Method could look like this:
void mapListView_SelectionChanged(object sender, SelectionChangedEventArgs e)<br />
{<br />
}
and you have to tell mapListView to call your method. you can do it in xaml like this:
<ListView Name="mapListView" SelectionChanged="listView1_SelectionChanged"
or programatically (after mapListView is created and initialized):
this.listView1.SelectionChanged += new SelectionChangedEventHandler(listView1_SelectionChanged);

When I try to perform the math below I get an answer of 0, but the result of the below should be 5.76
Int64 lpTotalNumberOfFreeBytes = 41085476864;
Int64 lpTotalNumberOfBytes = 712212955136;
Int64 strAnswer = ((lpTotalNumberOfFreeBytes / lpTotalNumberOfBytes) * 100);
Does anyone see what I am doing wrong here?
Thanks

hi,
int/int performs an integer division; you should consider one of these fixes:
- use float or double everywhere
- postpone division, hence do 100*int/int instead of int/int*100
(there is an increased risk of overflowing when doing all multiplies before all divides)
The above holds true in most programming languages (C, C++, Java, C#, ...).

You can use float everywhere as Luc adviced you. But if you for some reason need to store lpTotalNumberOfFreeBytes and lpTotalNumberOfBytes as Int64 you can covert their values in division expression like this:
((float)lpTotalNumberOfFreeBytes / (float)lpTotalNumberOfBytes )*100;
However this expression return float value so you need to change type of strAnswer from Int64 to float or convert explicitly convert result to Int64:
Int64 strAnswer = (Int64) (((float)lpTotalNumberOfFreeBytes / (float)lpTotalNumberOfBytes )*100);
But remember if you convert float to Int64 system will cut off everything behind decimal point, so in this particular case result 5.7687068 will be converted to 5.

Hello..
I've got an InvalidOperationException: invalid Value vor the OracleObjectMappingAttribute nNR
Could NET have a problem with casting NUMBER to int? Or have i to do something
special, because I'm using a OUT-only Parameter?
Here are my code:
PLSQL:
-------------
create type TESTOBJ as OBJECT (
nNR NUMBER;
sTEXT VARCHAR2(20);
)
create testproc(p_testobj OUT TESTOBJ)
as
v_testobj TESTOBJ := TESTOBJ(1,'Test');
begin
p_testobj := v_testobj;
end;
C# the Mapped OBj:
-------------------------------
public class OracleXTBQueueObj : IOracleCustomType
{
private int nr;
[OracleObjectMappingAttribute("nNR")]
public int NR {
get { return nr; }
set { nr = value; }
}
private string tEXT;
[OracleObjectMappingAttribute("sTEXT")]
public string TEXT
{
get { return tEXT; }
set { tEXT = value; }
}
public virtual void FromCustomObject(OracleConnection con, IntPtr pUdt)
{
OracleUdt.SetValue(con, pUdt, "nNR", this.NR);
OracleUdt.SetValue(con, pUdt, "sTEXT", this.TEXT);
}
public virtual void ToCustomObject(OracleConnection con, IntPtr pUdt)
{
this.NR = ((int)(OracleUdt.GetValue(con, pUdt, "nNR")));
this.TEXT = ((string)(OracleUdt.GetValue(con, pUdt, "sTEXT")));
}
}
C# the Factory:
-------------------------------
[OracleCustomTypeMappingAttribute("USR.TESTOBJ")]
public class OracleXTBQueueObjFactory : IOracleCustomTypeFactory
{
public IOracleCustomType CreateObject()
{
OracleXTBQueueObj obj = new OracleXTBQueueObj();
return obj;
}
}
C# the function, callin the PROCEDURE:
------------------------------------------------------------
public static void GetOO(OracleConnection conn)
{
OracleCommand cmd = new OracleCommand("UDT_TESTPROC", conn);
cmd.CommandType = System.Data.CommandType.StoredProcedure;
OracleParameter paramDaten = new OracleParameter("p_testobj", OracleDbType.Object, ParameterDirection.Output);
paramDaten.UdtTypeName = "USR.TESTOBJ";
cmd.Parameters.Add(paramDaten);
try { cmd.ExecuteNonQuery(); }
catch (Exception ex) //InvalidOperationException
{
Console.Out.WriteLine(ex.Message)
}
Console.In.ReadLine();
paramDaten.Value.ToString();
}
-----
Hope somebody can help me
thx in advance

hi there,
I am trying to make my service to insert to a database when it starts as follows :
protected override void OnStart(string[] args)<br />
{<br />
base.OnStart(args);<br />
string query;<br />
id += 1;<br />
<br />
SqlCommand comm;<br />
conn = new SqlConnection("my connection string");<br />
query = "insert into myTable values('" + id + "',lamya'" +"')";<br />
comm = new SqlCommand(query, conn);<br />
<br />
try<br />
{<br />
conn.Open();<br />
<br />
while (id >= 120)<br />
{<br />
comm.ExecuteScalar();<br />
query = "insert into myTable values('" + id + "',lamya'" + "')";<br />
comm = new SqlCommand(query, conn);<br />
id++; <br />
<br />
}<br />
conn.close();<br />
<br />
}<br />
catch (Exception ex)<br />
{<br />
}<br />
<br />
<br />
}
after adding an installer and installing the service using the Installutil.exe
when I start the service from the services manager this msg shows up:
The ServiceOnTest service on your Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the performance Logs and the Alters service.
where ServiceOnTest is the service name ,
just to know if it matters: the startup type is automatically and it run for the local System
what should I do to make it work, I need it to insert to the database and more but first I need to know what wrong I did?
Urgent help is needed , please
Thanks
There is always something to learn

You either have a startup error or your onstart event takes to long to complete and gets shut down.
The onstart event is only for service initialization code. You either need to spawn a worker thread at the end of onstart or have it call an exe that will perform the task you need done.
