Can any of you recommend a good C#-book? I've bought the "Programming C#" by Jesse Liberty, and it's quite good. But there's nothing about GDI+, and since I'm mainly interested in image analysis/processing and graphics I'd like to buy a book which contains some stuff about GDI+ and possibly also about Winforms. I've thought about the WROX Proffesional C# Programming, anybody read that?

Programming Windows with C# by Petzold ? This discuss Winforms , UI stuff and GDI+ ...
BTW , a C# is different of GDI+ , by your title I thought that you wanted a C# book like Inside C# by Tom Archer instead of a GDI+ book .
The Petzold book is quite good explaining all the UI and GDI+ stuff , but if you are interested in Image processing you better get a specif book about this, since I currently don't known any book that deals with it with C#, C++ and C are the common language used in kind of image processing algorithm books.
Cheers,

I'll second this book. Loads of good information on a variety of Windows topics.

It has only one chapter about GDI+,and you can read that chapter here.

Petzold is definately the book on GDI+. As for image processing, some clown has written a few articles on doing that in C# right here on CP. I hear he's an idiot, but there might be some stuff in there worth investigating all the same. :P
Why do you want to do image processing in C# ?

Let me guess? You're the sinister person behind those articles? I'll check 'em out. 
There's actually no particular reason why I'm want to do it in C#. It´'s mostly because it's a fun way of getting to use and learn C# since I find image processing interesting and great fun.

That's pretty much exactly why I wrote my first C# articles on image processing also )

Can anybody tell me what caused this error?
Assembly generation failed -- Referenced assembly 'Mazdak.WebModules.Accounts.Data' does not have a strong name

What are you trying to do to it?
To give an assembly a strong name use the sn tool to create a key file, then reference the key file in your assemblyinfo.cs file.
sn -k keyfile.snk
In AssemblyInfo.cs
[assembly: AssemblyKeyFile(@"..\..\keyfile.snk")] - assuming you place the .snk file in the root directory of your project.

But where is sn tool ? When I run
sn -k keyfile.snk<br /> in commandline windows tell me that it couldn't find that tool.
I have one .snk file in my computer and when I use it,it solve my problem but I don't how to create it myself.
Thanks James.

It is part of the SDK; you'll have to use the shortcut provided by VS.NET in the start menu... Start\Programs\Microsoft Visual Studio .NET\Visual Studio .NET Tools\Visual Studio .NET Command Prompt.
Or you can alter your path to include %windir%\Microsoft.NET\Framework\v1.0.3705\

Can you have MDI's\SDI's in C#, done enough dialogs but can you do 'proper' applications?;P

Yes you can.

As David said, Yes you can.
To add to that though there is an inherit difference between the way Windows Forms and MFC work. There is no difference between an MDI parent, MDI child, and a Dialog. All are created by deriving from Form and calling certain methods or setting certain properties.
For an MDI parent set the IsMdiContainer property to true. To create a MDI Child, assign the parent window to the child form's MdiParent property. To create a Dialog, use the ShowDialog() method.

Hi,All
I want to access Microsoft Excel Sheet in Visual C#.In one button click i am writting following code:
Excel.Application ExcelApp = new Excel.ApplicationClass ();
Excel.Worksheet sheet ;
sheet = (Excel.Worksheet) ExcelApp.Workbooks.Open("D:\\AccessExcelInVB\\Data.xls",1,1,1,1,1,1,1,1,1,1,1,1).Sheets.get_Item("Data");
MessageBox.Show( sheet.Cells.get_Item(12,12));
I want to access the data in (12,12)'th cell and show it in MessageBox,i need to compare it with string in further code.
But it gives error that object can not be converted to string.
Can anybody tell me how should i convert object to string?
Thanx and Regards

You need to manually call ToString() on it, but there is probably some Excel method you need to call to get the string out of it.

Hi,
When i use :
MessageBox.Show(sheet.Cells.get_Item(12,12).ToString);
it gives me string System.__ComObject
But i want value of that cell.
Also it does'nt have Value property to give me value of that cell.

According to a quick look at MSDN there should be a Value property on the Range object that refers to that cell.
ie, Range("L12").Value, I think you create the range object from the worksheet.

Hi,
Sorry to trouble you again but i am confused.
Excel.Application ExcelApp = new Excel.ApplicationClass ();
Excel.Worksheet sheet ;
sheet = (Excel.Worksheet) ExcelApp.Workbooks.Open("D:\\AccessExcelInVB\\EquipmentData.xls",0,1,1,1,0,0,1,0,0,0,0,0).Sheets.get_Item("Data");
now when i use sheet.Cells(12,12) and gives the Dot it does'nt show me anything,and it gives me error("Excel._Worksheet.Cells denotes a property where a method was expected").(DotNet does'nt support Default).
so i should use sheet.Cells.get_Item(12,12),but it does'nt show me Value property.
I am using Office2000 is it due to that?.
Thanx
Tushar

This code works for me with OfficeXP
Excel.Application app = new Excel.ApplicationClass();
Excel.Workbook wb = app.Workbooks.Open(@"C:\test.xls", 0,0,1,1,0,0,1,0,0,0,0,0, 0, 0);
Excel.Worksheet ws = (Excel.Worksheet) wb.Worksheets[1];
Excel.Range range = (Excel.Range) ws.Cells[12, 12];
textBox1.Text = (string) range.Text;
wb.Close(false, Type.Missing, Type.Missing);
app.Quit(); HTH,
James

I think you might want to try sheet.Cells(12,12).Value (and then maybe .ToString() )
