Hi, I'm a Java Developer wishing to Migrate to C#. Please provide me some ebook meant for Java Developers whiching to migrate to C#.
Thanks...
P.S: I'm new around here so please move my post to the appropriate section if it does not belong here.

Java and C# are very similar. I don't know of any ebooks, but I know there are a couple of books available for purchase. Overall, I'd say if you found some articles online ( just google it ), and then you started to play with C#, you wouldn't have much in the way of problems.

Like Christian said, Java and C# are quite similar. I learned Java at the university and C# on my own (and with help of Code Project articles  ). There isn't a real sharp learning curve. Only difference is the most of the classes you find in .NET versus Java. There are many that are similar. Have fun learning C# and you did pick the right forum for asking C# questions.
There are many very knowledgeable members on this site, so feel free to drop a question anytime

This should get you started!
P.S. -- My first experience with both C# and Java was to port a project from Java to C#! I found most of my job was to run find/replace to replace methods like String.length to String.Length etc... The biggest bug that I created while doing this was that String.substring in Java has the same parameters as String.Substring in C#, but they do different things (index to index vs index to length).
Good luck!

Hi frinds,
First of all thanks, I got the code to Convert CSV file to XLS file using Excel Application object.
My code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;
using Microsoft.Office.Interop.Excel;
namespace File_Conversion
{
class Program
{
static void Main(string[] args)
{
ApplicationClass app = new ApplicationClass();
Workbook doc = app.Workbooks._Open(
@"C:\GCProject\Input Example.csv",
Missing.Value,
Missing.Value,
Missing.Value,
Missing.Value,
Missing.Value,
Missing.Value,
Missing.Value,
Missing.Value,
false,
Missing.Value,
Missing.Value,
false);
Console.WriteLine("Reading CSV File........");
doc.SaveAs(
@"C:\GCProject\Output.xls",
XlFileFormat.xlWorkbookNormal,
Missing.Value,
Missing.Value,
Missing.Value,
Missing.Value,
XlSaveAsAccessMode.xlExclusive,
Missing.Value,
false,
Missing.Value,
Missing.Value,
Missing.Value);
doc.Saved = true;
Console.WriteLine("Converted CSV to XLS file");
app.Quit();
Console.ReadLine();
}
}
}
But Now, I have to get specified format, Like follows.
My CSV file Contains Data like.
-----------------------------------
Ex: DriverID | CustomerID | Ship to ID | Load # | BOL Date/TimeStamp |PrdNam
520 | 2355 - | 1 | 61953 | ############ | 1 Eth 87
My XLS file Contains Data Like.
-----------------------------------------------------------------------------
Ex: Field | Definition | Length | Starting Column | Ending Column |
-----------------------------------------------------------------------------
delimiter"
-----------------------------------------------------------------------------
TransType|Some Definition |1 | 1 | 1
|
-----------------------------------------------------------------------------
delimiter ","
-----------------------------------------------------------------------------
Termin ID | Some Difinition| 3 | 3 | 5
|
-----------------------------------------------------------------------------
delimiter ","
-----------------------------------------------------------------------------
Term SPLC | Some Difi | 7 | 6 | 12
|
-----------------------------------------------------------------------------
I got the code converting CSV file to XLS file. But What I need is Converted
XLS file should look like above format in Converted Excel sheet.
Any body have Idea !!!!
Hope I explained well.!
Thanks in advance.

Liyakhat.

here are 2 ideas:
1) do the open and save methods allow you to specify the format of the input/output? In the save parameter list there's XlFileFormat.xlWorkbookNormal - is there another format in that enumeration that better represents what you want? Try looking here[^] for information about those methods
2) parse the .csv and print your .xls files manually. This will obviously require more work but will ultimately give you much more flexibility with your format conversions. Here[^] is a short example of creating your own Excel file.

Hi Jammie,
First of all thanks for the reply.
I have tried with the "Open" and "Save" methods of the input/output. :(I have tried with the XlFileFormat.xlWorkbookNormal there is not methods to show in my specified format
I have read those two links which you have sent. But I m not able to find any info related to my task.
Do you have any new Idea ?
Thanks,
Liyakhat

The most versatile method is going to be to parse the .csv file and create a .xls file manually.
A .csv file is just a text file, so one method of parsing it is to open and read it with a StreamReader[^] and read it line by line. For each line that you read use the split[^] method to separate the values by comma.
Then to create your own .xls file just follow the example in the link that I gave here[^]. All you need to do is get a workbook like they do with this code:
oXL = new Excel.Application();
oXL.Visible = true;
oWB = (Excel._Workbook)(oXL.Workbooks.Add( Missing.Value ));
oSheet = (Excel._Worksheet)oWB.ActiveSheet;
and then write the data into the worksheet however you want. The cells in the .xls file can be accessed just like a two dimensional array, so you can arrange the data however you want. Then save the workbook and you're done!
Oh, and it's Jim, not Jammie

hi,
I am working on web application(ASP.NET ,VB.NET) and some reports push on server daily.
GZ (application like winzip) is installed on only server machine not on client machine.
I want to open report in GZ on server from any client machine and print on printer.
Can I do this ?
thanks in advance!!
|
|
|
|

No - you can not grab a file from the client, they have to send it to you. You could write a page which loads the report and starts printing, I believe, but at best it would bring up the print dialog, you can't start the printer from javascript.

Hello everyone,
I am learning how to use C# to implement an OLE DB provider (a simple one which is based on CSV file format). I can not find any samples from MSDN (all samples are C++).
Any reference materials?
thanks in advance,
George

Here is a quick google search[^]. Hope it helps you some

Hi Paul,
Almost all on the list are about how to use OLE DB provider (as an OLE DB consumer), but what I am looking for is how to implement OLE DB provider, here is the related sample in C++,
http://msdn2.microsoft.com/en-us/library/ms715011.aspx
I am looking for a C# sample.
regards,
George

I must have misread your original post earlier. From a quick glance of msdn link, porting from C++ to C# shouldn't be that difficult.

Hi Paul,
Do you know whether there are any tools to convert source codes from C++ to C#? The sample has almost 2k lines of code.
regards,
George

I don't really know of any tools for converting from C++ to C#. How much C# do you know? Are you learning it?

Here is one, I don't know how good it is...

Forget it, it couldn't even translate a simple Hello World prog...

i have in my application combobox that contain all logial drives into my pc
when i try to click drive a when no floppy in it error happen
-how to check if the selected drive is floopy or cd
-how to check if it has no files or folders in it
md_refay

You can't check if a has any files in it without trying to read it. If your file system reports the a drive, that's what will happen. However, it is possible to work out what is a USB drive, what's a floppy, a CD drive, or a hard drive. DriveInfo[] allDrives = DriveInfo.GetDrives (); Now if you iterate over those objects, each represents a drive, and what type of drive it is.

Can someone publish C# code to make use of CreateProcessWithTokenW function, so that i can run process just by getting token from current user, instead of passing user/pw for every run (WindowsIdentity.GetCurrent().Token)
Basically trying to extend impersonation functionality to disconnected functions like Process.Start()
Impersonation example:
http://www.codeproject.com/csharp/zetaimpersonator.asp
Many thanks.
