itemcommand not getting called.

How did you check? Put a breakpoint in the method?

I'm not good with ASP, but you might want to compare your code with the sample on MSDN[^].

Thank you Eddy for your reply..

I have already check with break point. but only itemcommand is not getting fired with repeater(Note: Repeater is inside of ajax modalpopup.)
when i use without ajax modalpopup than it looks good.

Hi I used the axShockwaveFlash controls to show "swf" under vs2012(c# winform). The swf file is created by flash builder4, and it contains the modle which is created by away3D.But the screen displays white,however I used axShockwaveFlash controls to show "swf" which is without away3d ,and swf runs normally .
Besides the swf canbe played in the flash player.I excluded the problem of sandbox security.If someone can help me to show swf I'll appreciate about it！

Flash is not a native component of the .NET framework; you'll probably get better support at one of the flash-forums. Adobe has their own[^], click on 'discussions' to get a list.

I created a generic type called: Table<T>, and I create an instance of him using T as 'OrderItem' element.

Now I need to set him into other instance that should suppot multiple types, so I decided to use object:

private Table<object> currentTable;

Now I'm trying to set the OrderItem table, to the Object table:

currentTable = mainWindow.OrderItemTable;

And I'm getting this error:

"Cannot implicitly convert type 'BusinessLogic.Table<Entities.OrderItem>' to 'BusinessLogic.Table<object>'".

OrderItem isnt implement IConvertible, so I can't use ConvertType, also casting isn't working.

Any suggestions?

Thanks.

You can't convert a collection of anything to a collection of something else:

List<string> ls = new List<string();
List<object> lo = (List<object>) ls; //Compiler error!

Unless the collection defines a cast operator that supports it.
So you will need to explicitly define a conversion as part of your generic class:

public static implicit operator Table<object>(Table<T> t)
    {
    Table<object> to = new Table<object>();
    ...
    return to;
    }

How you actually do the conversion is up to you!

You will probably need to explicitly declare a conversion back again as well...

You have to create a driver for your printer and install it on your system. See http://msdn.microsoft.com/library/windows/hardware/ff557573[^] for more information.

Since a driver is (effectively) part of the Windows OS you will need to write it in C/C++.

28-Dec-13 2:20

If you want to create a new printer (real or virtual) then you will need to install a driver for it, and that will need to be written according to the WDK. Go to the link I gave you and study how to do it.

How I can add local printer programmactly

29-Dec-13 2:08

Bit by bit.

You're asking three questions here; how to display an image in CR, how to fetch an image, and how to work with a combobox. I assume that the combobox is on some WinForm?

Check out Image in Crystal Reports[^] Smile | :)

Hello

I used this code to add printer but it did not work

try
{
oManagementScope = new ManagementScope(ManagementPath.DefaultPath);
oManagementScope.Connect();

ManagementClass oPrinterClass = new ManagementClass
(new ManagementPath("Win32_Printer"), null);
ManagementBaseObject oInputParameters =
oPrinterClass.GetMethodParameters("AddPrinterConnection");

oInputParameters.SetPropertyValue("Name", "testprinter");

oPrinterClass.InvokeMethod("AddPrinterConnection", oInputParameters, null);
return true;
}
catch (Exception ex)
{
return false;
}

What does "it didn't work" mean?

Where did you specify what printer to connect to? What driver to use? What printer settings (port, ip, etc)? I can't imagine you would get a working printer just by telling Windows the name of one...
