hi,
Easiest way to run a program is add application to the startup directory..
In addition,You can give this option when building setup to the Application exe.
(for example installshield express setup wizard will do it for you)

Hello every body,
I know C and a little OOP and C++. What should I do for starting C#? Should I learn OOP or C++ at first? Give me some reference, please.
Best.

A beginner's book for C# would not be a bad idea either

Can you practice what you teach?

You can't really learn C# without learning OOP, because C# forces OO, unlike C++, which just allows it. I'd suggest buying a book like 'Inside C# Second Edition' by Tom Archer ( actually, not LIKE this book, you need this book IMO ). If the book is too heavy for you, buy something like the Jesse Liberty book on C# from O'Reilly, and then move into Tom's book as you are able.

hi all
I am going to develop payroll using C#.I want to find out best way to communicate with databases.I have heard Microsoft Enterprise Library can give a support to easier the coding..
Can any one tell me purpose of the Enterprise Library(Pattern and Practice)
any suggestion ,greatly appreciated.
Thanks in advance..

Microsoft Enterprise Library is an Application Framework consisting of 7 or 8 Application Blocks (can't really remember the number). Each block deals with a different category of common issues that you would otherwise had to go through in your code (such as logging block, database block, exception block, etc.). It's not only used for database development.
You have the option to select which of the blocks you want to include in your code, and each one of them comes with a variety of classes and methods that ease the development and handle things in the Microsoft recommend way (afterall they are written by Microsoft).
When it comes to Databases, from what I can remember, currently the Ent. Library supports only Oracle and SQL Server. I am not sure about the rest (Odbc and so on).
If you are only interested in Database development then a good alternative would be the RapTier framework. Google for it, it's quite good, it supports all database types, and it comes with a good documentation.
Hope this helps.

Polis

Suppose a process notepad.exe has started. I like to know how to detect a period of inactivity of a user for that process, for instance how long the user has not entered anything into notepad.Maybe System.Diagnostics can solve this problem but i did not find much information on the websites.Hope to gather some advice here.
Thanks a lot

Hello, everyone.
I have a problem about the coordination system of mouse pointer in
different monitors.
My windows application program is developed using MS Visual Studio
.Net 2003 in C#.
First I insert a MS chart component into the form. Then I added a tooltip
into the form to show the x, y values of the location of mouse pointer when the mouse moves into the chart component.
I tested my program in a desktop with an old Phillip S105 monitor, then in
a desktop with hp 1730 monitor, and lastly in an Acer laptop.
The tooltip output values from Phillip S105 monitor are completely
different with the results from other two monitors of the same position
on the chart.
The locations and sizes of the chart are exactly the same because I use
the same program to test. The resolutions of monitors make no differences.
Does anyone have such kind of problems before?
Please help.

Your monitor does not interact with your computer, it simply accepts data and displays it. There is simply no way that the monitor that's plugged into your PC could make your code behave differently. You need to look again to see what the source of the problem is.

I have a dll(in C++). Now I must use a method in it. The method has a parameter of "double **", so how can I managed it to .net?
The class Marshal in .net include a method "Copy", but it can only copy the data of one dimesion from managed code to unmanaged or vice-versa. How to copy a 2 dimesion array ? Please help me !
thanks a lot.

A ** is a jagged array - perhaps you can create the first array level, and then step through and use Copy to create each of the sub arrays ?

Can you give me an Example?

Sorry, I've not tried it. I suggest you find an API function that uses a double ** ( assuming this isn't one already ), and try www.pinvoke.net, see if they have a signature for it. I'd have expected double [][] to work ( it is the same as a double ** ). Actually, pointers are supported in C#, perhaps you could just use pointers directly ( dunno here, I've never tried, but I have certainly used pointers )

hi,
dll must have public methods..
if dll is a componnet,you can add it to the .net using refferences-->>add reference..
after that it is easier for you..
if not you have to import dll like this:
[DllImport("abc.DLL",EntryPoint="methodname",ExactSpelling=false,SetLastError=true)]static extern int methodname(double[][] dd);
I think you may help above details..
regards ,
pubudu..

hi pubududilena，
it seems that "double**" is not equal to "double[][]".
hope for help
|
|
|
|
|
hi
try like this:
static extern void methodname(out double dd);
or
static extern void methodname(ref object dd);

I am using C#.NET and I have a form called frmLogin. I am trying to open it from a form called frmMain, this is the code:
frmLogin.Show();
What is wrong?
It says the error is "An object reference is required for the nonstatic field, method, or property 'System.Windows.Forms.Control.Show()'"
Thanks everybody!
|
|
|
|
|
Have you instatiated it
i.e
Form frmLogin = new FormLogin(); //whatever you have called the new form
frmLogin.Show();

I am looking for some documents/whitepapers/whatever that would point to good coding conventions for ASP.NET/C# forms development. If anyone has some tips or pointers, that would be much appreciated as well.
Thanks in Advance

The book 'Code Complete' has some good general suggestions. Beyond that, perhaps have a look through some online samples and see what conventions are used, and familiarise yourself with the general .NET conventions ( for example, if you want to write CLR compliant code, don't rely on case for variable names, as the CLR can't do that, because of VB.NET ).

I know this is not the first time this question has been asked, but I need help playing MP3 audio in my C# application. I know the obvious route would be to use the Windows Media control, but I can't figure out how to add it to my program because Microsoft's instructions assume that I'm using Visual Studio, which I am not. Anyone know how I can add it to my program using SharpDevelop, or another possible route? Keep in mind that I'm a beginner with C#.
|

|

Basically, to play MP3's, you'll need COM interop, be it WMP or something else. Sharp Develop doesn't allow you to import COM objects ?
