Hiho
Are there good reasons available, to chose c# instead of vb?
Currently i know:
C#:
++
case sensitive
block-comments
cats
unmanaged code might be easier
closer to c++ / java syntax
arrays are defined in a proper way (elementCount instead of the index of the highest value)
unsigned datatypes
vb:
with
case insensitive (some guys think thats a benefit - im not so sure)
events might be easier
Is there some kind of in deep comparison available?
Maybe other reasons:
Member base of both languages might differ => but its rather hard to estimate both communities.
thx

I know for a fact that C# is more powerful and interfaces with all that the .NET framework offers, which VB .NET does not. If you're going to learn I new language, I would suggest C# since its used in industry extensively.

Really? That goes both ways.
For example, C# supports Unsafe code blocks, VB doesn't. VB supports optional parameters, C# doesn't.
It's just a matter of preference. They both target the .NET Framework quite well, each with it's own limitations.
I'd agree that learning C# would be very useful to him, but I'd also have to add that learning every language you can would be very useful to prospective employers even more so.

Sometimes its not so easy ;o)
I see 2 possibilities:
a) convince my boss that c# is better
b) convince myself that vb is as good or even better.
Thats the reason for my vb vs. c# comparison research.
thx

There are no absolute, water-proof and one-sided reasons for choosing C# over VB. As VB uses the same framework, anything you can do in C# you can also do in VB. For an example, the untyped datatypes that you mention is a part of the framework, so of course they are also available in VB.
It's more a matter of taste. The difference is how you do things, not what you can do. For an example the event handing is easier in VB, if by easier you mean less typing. If you want to be able to read in the code what happens, the C# way is easier.
BASIC (Beginners All-purpose Symbolic Instruction Code) was a simple interpreted language in the beginning. Many attempts have been made to make it compiled and object oriented, and perhaps VB is one of the best, but my opinion is that the language still suffers from it's history. C# on the other hand is a language that is compiled and object oriented right from the start.

"Flatten" the Xml to a physical disk file and then "point" IE to that file; if you have Xml file types bound to IE, then you can use a ShellExecute command on that Xml file and it should open in IE.

Does anyone know of any known issues with Microsoft IE WebControls? We have
never used WebControls in our project and need to
know if any known security holes exist specific to IE WebControls.

Hi Howzit,
I am used to VB .NET. When you type "private sub whatever" and press enter, it creates a nice little nice procedure, with an "end sub" and everything.
In C# when I type for e.g. "private static void whatever" and press enter, it does not automatically put in the braces, is this how C# works? I assumed it would put the braces in automatically? The same applies to typing for e.g. an "if (asdf=1)" statement and pressing enter, should it not put the braces in for me?
Maybe its a setting?

It doesn't put the braces in for two reasons:
1. C# is not line based, as VB. A new line doesn't mean that the header declaration is complete.
2. In some cases the parenthesis after the parameters is not the last part of the declaration. It would be confusing if the editor would fource the braces in when there still is more things that you can put there.
Example: This is perfectly valid code in C# (if perhaps badly structured):
public
class
A
{
public
A
(
)
:
base
(
)
{
}
}
Notice the call to the base (object class) constructor call after the parameter paranthesis.

It is how the IDE works.

Is it really such a big deal to type two braces?
I tried Visual Assist, which does that sort of thing for you, but I got rid of it because it was just plain annoying.

I don't mind typing braces in but I just had to ask! I am really starting to enjoy C# now, its quite an adjustment from VB6 & VB.net

Perhaps if you undo actions back to the starting state, you can close Excel without getting the confirmation.

Hi,
u can do that by setting the variable of Excel.Workbook to true.
i.e. if u have an object of Excel.Workbook called WB
then just write WB.Saved = true; before closing the application or excel application.
Hope that works for u
Regards,
Pramod

I post the message in message boards, after this I try to use worksheet.saveas method that save to my driver, then close the worksheet.
app.Workbooks[1].SaveAs(@"c:\temp.xls", Missing.Value, Missing.Value,
Missing.Value,Missing.Value,Missing.Value,
Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,
Missing.Value,Missing.Value, Missing.Value, Missing.Value, Missing.Value);
app.Application.Workbooks.Close();
app.Application.Quit();
app.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject (app);
the work sheet been closed, but the process still in task manager until my application been closed. Why?
so ,I more wrote code
Process[] procs = Process.GetProcessesByName("EXCEL");
foreach (Process proc in procs)
{
if (!proc.CloseMainWindow())
{
proc.Kill();
}
}
GC.Collect();
app = null;
At last, the excel porcess been disappeared in task manager.

Take a look at application.DisplayAlerts the .saved can be tricky, and there are situations where the excel doc will toggle it without you explicitly setting it. .Displayalerts suppresses ALL warnings from the excel document, but it definetely gets rid of the "do you want to save" issue.
