You need to set the Owner or Parent property on the form.

Package package=GeneratePackage(); //Generate package is a my function
Application app=new Application();
app.SavetoXML("path",package,null);
DtsConnection dtsCon=new DtsConnection();
dtsCon.ConnectionString=package.GetPackagePath();
dtsCon.Open();
DtsCommand dtsComm=new DtsCommand(dtsCon);
dtsComm.CommandText="DataReaderDest";
IDataReader reader=dtsComm.ExecuteReader(CommandBehaviour.Default);
ds.Load(reader,LoadOption.OverwriteChanges,reader.GetScehmaTable().TableName);

The main thing you need to know about object cleanup, is call Dispose if it's available.

I googled for trace collector, where did you hear about it ?

Hi,

I wish to disable toggling of check box in checked list box (C#). If my check box is checked user shall not be able to uncheck it and vice versa but text should be allowed to be selected.

In list box i was able to set colours for items but if i set color i am not able to select any of item. I wish to give colors to items in list box but also i should be able to select the items.

Please help if someone knows the solution of above 2 issues.

It sounds like you don't whant to set "Enabled" to false.
What you can do is handle the "ItemCheck" event and reset the Current value property of ItemCheckEventArgs.

private void checkedListBox1_ItemCheck(object sender, System.Windows.Forms.ItemCheckEventArgs e)
{
	e.NewValue = e.CurrentValue;
}

I think you can select, but the color changes if you do so.
Maybe by handling the "SelectedIndexChanged" and reseting the color you can be successfull.

Hope it helps!

All the best,

Hi Experts.
How can i check a condition during the apllication when my application is idle.

Like in vc++ there is a OnIdle() message handler.
Is this like in c#.

Thanks in advance.

Use the Application.Idle event.

Standards are great! Everybody should have one!

Hi,

I'm working in a dynamic code generation project. While creating aspx pages, I'm using such code:

string s=<TD><asp:label id=lbl" + ctrlId + ">" + caption.Trim() + " Runat=server</asp:label></TD>" + Environment.NewLine + <br />
									"<TD><asp:TextBox id=" + ctrlId + " Runat=server></asp:TextBox></TD>";

But the "Environment.NewLine" doen't seem to function the way it is supposed to, because i don't get output in 2 separate lines. In the output after adding all such html code, I see "\r\n" instead of "Environment.NewLine" and the everything is in the same line in the file.

Could someone point out whats going wrong here.

Regards

Blumen23-May-07 18:53

The code is not displayed properly what i copy-pasted. Pls find it below:

<asp:label id="lbl"" +="" ctrlid="" "="">" + caption.Trim() + " Runat=server" + Environment.NewLine +
"<asp:textbox id=" + ctrlId + " runat="server">";

First of all, check 'ignore HTML tags' when posting HTML

second, there is an ASP.NET forum

third, a newline doesn't generate a break in HTML. The <br> tag does. It doesn't need a /, but I would use <br/> to make it XHTML.

I am writing the output to a file, so that I can create an aspx file later. Thats why i used NewLine property.

OK, that will work in your file, but still won't work in HTML. You can use Newline for formatting, but you need the br tag for the browser.

bool bFlag = true;

private void timer1_Tick(object sender, EventArgs e)
{
    if (bFlag)
    {
        this.Icon = Icon.ExtractAssociatedIcon(@"C:\FirstIcon.ico");
        bFlag = false;
    }
    else
    {
        this.Icon = Icon.ExtractAssociatedIcon(@"C:\SecondIcon.ico");
        bFlag = true;
    }
}

Maybe my depiction is blurry.

my meaning with the icon is the rectangle that it delegates a form
in the taskbar.

Are you sure the Icon class can make it glitter?

I'm quite sure there is an easier method; something like this.focus() or this.activate() but it doesn't seem to work...

On the other side this does work. You'll need to allow unsafe code in your project

[DllImport("user32.dll")]
public static extern bool FlashWindowEx(ref FLASHINFO fInfo);

private void timer1_Tick(object sender, EventArgs e)
{
unsafe
{
FLASHINFO fInfo = new FLASHINFO();
fInfo.cbSize = sizeof(FLASHINFO);
fInfo.dwFlags = 2;
fInfo.hwnd = this.Handle;
fInfo.uCount = 2;
fInfo.dwTimeout = 0;
bool result = FlashWindowEx(ref fInfo);
}
}
}
}

public struct FLASHINFO
{
public Int32 cbSize;
public IntPtr hwnd;
public int dwFlags;
public UInt32 uCount;
public int dwTimeout;
}
