Hello,
I have a problem using the PrinterSettings property. I am trying to get what the user enters in the PrintDialog...
<br />
private void mnuPrint_Click(object sender, System.EventArgs e)<br />
{<br />
System.Drawing.Printing.PrinterSettings settings = new PrinterSettings(); <br />
printDoc.DefaultPageSettings = pgSettings;<br />
dlgPrint.Document = printDoc;<br />
if (dlgPrint.ShowDialog() == DialogResult.OK)<br />
{<br />
settings = dlgPrint.PrinterSettings; <br />
printDoc.Print();<br />
}<br />
}<br />
Then, when i try to read the values in settings it don't get what the user entered. For example, if i put:
short a = settings.Copies;
a will equal 1, even if i entered 5 copies in the PrintDialog. If anyone can tell me how to get the PrinterSettings the user entered. It would be greatly appreciated.
Thanks

System.Drawing.Printing.PrinterSettings pr=new System.Drawing.Printing.PrinterSettings();<br />
PrintDialog dia=new PrintDialog();<br />
dia.PrinterSettings=pr;<br />
short a=0;<br />
if(dia.ShowDialog()==DialogResult.OK)<br />
{<br />
a=pr.Copies;<br />
}<br />
MessageBox.Show(a.ToString());

Hi there,
Thank you for your reply. Unfortunatly, it still doesn't work.
I found what the problem was, after spending a lot of time searching about this silly problem, i found this :
http://support.microsoft.com/kb/331134[^]
So, i guess that this is my problem (I am on Framework 1.0)
Anyways, thanks for your help!

I created a form without title bar named frmNoTitle. I set up the form properties like:
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.ControlBox = false;
this.MaximizeBox = false;
this.MinimizeBox = false;
In the main MDI form, I have a menu to open thisfrmNoTitle form. I add following code in the menu's click event:
frmNoTitle frm=new frmNoTitle ();
frm.MdiParent=this;
frm.Show();
This works fine except that I noticed the frmNoTitle form's title bar(min,max,clos buttons) flashes for a very very short time, then diappear
I looks like that the program displayed the form title bar first, then make it invisible.
How I can get rid of it?
TIA

Hello everybody,
I have developed a Windows Desktop application in Visual C# .Net using Window forms and I am using a context menue and a notify icon to launch the application in the task bar.
The application consists of different Window Forms, so that I am switching between different forms the whole time. Unfortunatly, each time when I close one of the windows (Window Forms), a new notify icon appears in the task bar, and they only disappear after I have closed the whole application. I am using the Close() method to close any forms.
Does anybody have an idea why that happens and how I can avoid it?
Thank you very much!

When closing the Form you have to manually hide the icon. I've ran into this small bug before.
Anyways... I think it would be better to associate the icon with one form instead of destroying and recreating it every time. Just hide the form. Of course considerations for resource usage.

Hi CPs!
I'm currently writing my first application that uses a NotifyIcon and everything works fine except the following two things.
1. I want to hide the NotifyIcon as long as the main form of my application isn't minimized. But I'm not sure how to detect the "Minimize event" as their is no such event or I'm to stupid to find it. So I thought about catching the Resize event of my form and querying the WindowState property there. Would this work or is there a better way?
2. I want to hide the main form of my application and only display the NotifyIcon if my application was started by Windows Autostart, whereas the main form should by shown if the user "normally" starts the application. Is their any way to detect this?
THX in advance

Here is a simple way to check to see if your application is being Minimized. What you are going to do is simply override the WndProc and check for a few message values:
int WM_SYSCOMMAND = 0x0112;
int SC_MINIMIZE = 0xF020;
protected override void WndProc(ref Message m)
{
if(m.Msg == WM_SYSCOMMAND)
{
if(((int)m.WParam & 0xFFF0) == SC_MINIMIZE)
{
MessageBox.Show("I'm being minimized");
}
}
base.WndProc(ref m);
}

You could add a parameter to the autostart shortcut and check for it when the program starts.
Or check the TickCount. If it's really low, the system was just started

The possibility with the command line parameter came to my mind too shortly after posting. Guess I will use it, cause the TickCount may be a bit imprecise .

Say, the dataset is called dset, for some reason!
then dset.Tables[0].Rows[0].ItemArray[0].ToString() should retrieve the first column in the first row in the first table, which you seem to be absolutely certain of. 
Cheers!

Assuming you want row x, column y, and assuming the DataSet object is named "ds" and DataTable's TableName is "MyTable", how about:
object value = ds.Tables["MyTable"].Rows[x][y];

i have the following problem:
1. i have an interface with few methods which i cannot change.
2. i am creating a base class that realizes the methods which are defined
in that interface (but this class doesn't inherit from the interface).
This class will be called the "Base" class.
3. i have 2 other classes which inherits from both the interface and the base class. (will be
referenced as Classes A and B)
what i need is this:
the base class should hold all the similar functionalities (methods) for both A and B which are also defined in the interface. i want to remove all these methods from A and B.
it doesn't compile with an error that says i am not realizing the interface's methods inside A and B (but they ARE realized in the base class which A and B are inheriting from).
is there a way to make this work?
Thanks.

Simple: implement the interface on Base and mark the methods that need to be different on the derived classes as "virtual" or "abstract". Then, override as needed.
Yes, even I am blogging now!

"RasGetProjectionInfo" function in MSDN.
this is right?
[DllImport("Rasapi32.dll", CharSet = CharSet.Auto)]
public static extern uint RasGetProjectionInfo(IntPtr hrasconn,RASPROJECTION rasprojection,[Out]RASPPPIP[] test,ref int size);
public struct RASPPPIP
{
[MarshalAs(UnmanagedType.U4,SizeConst=4)]
public uint dwSize;
[MarshalAs(UnmanagedType.ByValArray,SizeConst=44)]
public byte[] bt;
}
public enum RASPROJECTION
{
RASP_Amb = 0x10000,
RASP_PppNbf = 0x803F,
RASP_PppIpx = 0x802B,
RASP_PppIp = 0x8021,
RASP_PppCcp = 0x80FD,
RASP_PppLcp = 0xC021,
RASP_Slip = 0x20000
}
when i call this function in C#,it's return 632 or 87...
int ii = 0;
RASPPPIP[] rasPPPIP = new rasPPPIP[1];
rasPPPIP[0].dwSize = (uint)Marshal.SizeOf(typeof(RASPPPIP));
RasFunction.RasGetProjectionInfo(connectedRasHandle,RASPROJECTION.RASP_PppIp,rasPPPIP,ref ii);
"connectedRasHandle" is correct,and i can call RasHangUp(connectedRasHandle)
I'm going crazy ...
Help !

MSDN docs have it down in black and white. A non-zero return code means that you have a problem.
632 - ERROR_INVALID_SIZE - The dwSize member of the structure pointed to by lpprojection specifies an invalid size
87 - ERROR_INVALID_PARAMETER - One of the parameters is invalid

But , How can I do?
I call this function in VC++6.0 is correct!and the dwSize=48,In C# as same as VC++.
