HI all,
Can someone please help me to convert this VB code to C#.
Thanks!
Private Sub DataGrid1_ItemDataBound
(ByVal sender As Object,
ByVal e As DataGridItemEventArgs)
Handles DataGrid1.ItemDataBound
Dim img As System.Web.UI.WebControls.Image
If e.Item.ItemType = ListItemType.AlternatingItem Or
e.Item.ItemType = ListItemType.Item Then
img = CType(e.Item.Cells(1).Controls(1),
System.Web.UI.WebControls.Image)
img.ImageUrl =
"webform2.aspx?id=" & e.Item.Cells(0).Text
End If
End Sub
EWIN

There are conversion tools on the web that are free. It's also a good exercise to learn to do this.
The big trick is, there is no C# syntax for 'handles', you need to assign the handler on page load or in the aspx.

Translation of most VB.NET->C# (and other way around) is pretty simple but with a few things that are specific to one language and not the other. One thing that you could do to learn how one thing is written in language X vs. language Y is look at the direct translation from MSIL.
You can download .NET Reflector from -> http://www.aisto.com/roeder/dotnet/[^] and load in an assembly with the above method in it (must be compilable at this point) and .NET Reflector will allow you to toggle between VB.NET and C#.
.NET Reflector merely looks at the IL and translates to the language of choice from that (in most cases you can simply recompile from it as it does a fairly good job at it).
Hope this helps a little,
Cheers,

Hello everyone,
What are the differences between [Serializable] and [Serializable()]? From IL code, I think they should be the same? So, we have two ways of syntax to write the same thing?
thanks in advance,
George

I am trying to work out how any of your questions help you to either study or use C#.
I doubt they differ. Look at the MSIL to be sure. If MSDN doesn't tell you how they differ, they don't differ in any meaningful way.

Thanks Christian,
From IL, they are the same. Any ideas? I have not found any MSDN mentioning this topic.

They are same. By writing [Serializable] and [Serializable()], you are calling Serializable attribute classes parameterless constructor. If Serializable attribute class don't had a parameterless constructor, you won't be able to write [Serializable], you should write [Serializable(parameters)] instead.

Considering the number of questions of this type you keep asking, and your lack of acceptance when you are given a good answer, why not go out and buy yourself a book on C#. Most of you questions are about subjects that, in the real world of programming, make very little difference to anyone - the amount of bloat that MS build into their systems means that the odd little tweak you can do by worrying about what MSIL is generated are really meaningless. If performance worries you, good coding practice and structure will give bigger gains that worrying about a few extra lines of MSIL.

hy everyone!
i do have a strange problem maybe someone of you knows a solution to this or a good way to find out:
i do have a console application (parser) which reads from file, splits the input if necessary and writes the data to outputfiles. the number of outputfiles depends on the input type, meaning if the file is split into parts then there are as many outputfiles as there are parts.
the program searches a directory using a search pattern, then splits the file if necessary and performes the parsing and inserts data which match the tokens in the output template and renames the final file from tmp to the final extension.
sounds easy. on my system it works well (Vista, Visual Studio 2005).
But when I execute the program on a Win2003 Server it looks like some parts of the code are left behind.
e.g. i do have two files, the first one is split into two parts, but i do only get one output file. a second file which is parsed afterwards (the instance is still running because i first read all filenames which match the pattern) and is not split returns the one outputfile.
so somewhere the second outputfile of the first inputfile is lost, the program doesn't crash it doesn't write a failure into log (because i write a log entry when starting, when finishing and when an exception occures). the start logentry is in the logfile, but no failure nore the finish entry. but both files are moved to the success folder and not to the error folder, so it looks like it was parsed correctly. but after the move statement in the code the logmessage is insert into the logfile. so the code has to be used because the one file is there as well.
so to me it looks like as if the parser just sends some input to nirvana and not to the output or "ignores" parts of the code.
and the strange thing is, when i run the program on my vista machine, everything is ok.
well, the main problem in my case is, i can't install Visual Studio on the server because it is not mine, it's a client's machine i programmed the parser with. so my first idea would be to insert logfile entries when entering one of my functions and one when leaving to see, when the operation suddenly stopps.
did anyone of you encounter similar problems during coding console applications in circumstances like me? or does anyone of you have a hint on which could be the reason to help me solve this strange behaviour more quickly?
thanks for any advice and hints, because i nevery had behaviours like this before. all my programs i coded bevour could be used no matter which operating system or hardware was used. and as i described above, why is the operation successful on the one hand side and on the other side it is not because the output is lost somewhere?! 
stephan.

No idea. But make sure that .net is updated?

Use multiple data sources, not just one.

Do you know where I can find a list of all compiler warnings associated with each compiler warning level?
For example, Warning Level 1 is associated with CS0657, CS0658, CS0659....
|
|
|
|
|
|
Yeah - That is the information that I am looking for.
However, I need the warnings in more of a spreadsheet format for easy reference.
The format of the information at the url requires me to click on the compiler code in order to see the compiler message. I need to see that information on the same page.

Hi - I have a MonthCalendar control which displays 12 months and all I'd like to do now is print the stupid thing. Is there anyway to accomplish this?
|
|

You could manually write a print routine (good luck  ). Or you could try creating html or rtf code and print the contents from a richtextbox or a webbrowser control. Or you could look into screen capture and printing screen captures.

I ended up just printing the screen:
void btnPrintCalendarClick(object sender, EventArgs e)
{
graphics = this.calendar1.CreateGraphics();
Size _size = this.panel1.Size;
calendarBmp = new Bitmap(_size.Width, _size.Height, graphics);
this.calendar1.DrawToBitmap(calendarBmp, this.calendar1.Bounds);
PrintPreviewDialog pvw = new PrintPreviewDialog();
pvw.Document = this.printDocument1;
pvw.ShowDialog();
}
void PrintDocument1PrintPage(object sender, PrintPageEventArgs e)
{
e.Graphics.DrawImage(calendarBmp, 0, 0);
}

Hi,
I have a two part question, can be written in either C++ or C#
1. How to figure out which versions of VC++ runtime installed on the computer?
2. How do I write a bootsrap program that checks if Visual C++ 2008 Libraries installed or not and then goes and install Visual C++ 2008 Redistributable Package if not installed?
Thanks
Ben

1. IIRC, there's a Windows Side by Side (SxS) "assembly cache" for native dlls that might contain this information. Ask in the C++ forums for more info.
2. There's already a bootstrapper package in Visual Studio 2008 for this. See \Microsoft Visual Studio 8\SDK\v2.0\BootStrapper\Packages. Or, if you're building your own setup program inside Visual Studio, right-click on your setup project, Add Merge Module, then it will list the VC 2008 modules to include.
Life, family, faith: Give me a visit.

How can I control the types of warning that VS2008 displays?
For example, the compiler currently warns of public members without comments. I want to supress this warning. How can I do that in VS?
