That's not surprising - Microsoft hired the guy that created Delphi to create C#

Not all, no. Althought I think that many people will still make the move.
Hamed Mosavi wrote:

I don't understand what "MFC like" programming is. MFC (Microsoft Foundation Classes) is a framework that sits on C++ that allows you to create various types of applications. The .NET Framework is similar but it is used by managed languages, such as C#, VB.NET or Managed C++, that allows you to build various types of applications.
Hamed Mosavi wrote:
Is Microsoft going to lose her C++ programmers?
No. There are many things that cannot be written in a managed language. There are many applications that have been evolving for years in C++ that won't be re-written for C# as C# has various interop abilities in order to allow legacy applications to integrate.

It depends on your point of view. I switched in 2001 to .NET and I love it. I love the ease that I can create applications. I love that it allows me to integrate with older software. I love the fact that writing code that queries databases is so much easier that it was.

I totally agree. For all its problems, .NET shines because of the BCL. It simply lets users program at a higher level. It's been very well designed too. The number of times I've expected a method to be in a certain class, only to find it precisely there with the same name, it's really stunning.

Hi,
Thanks alot for your answers.
I think my weak English once again made some problems,Sorry!;P
When I say "MFC Like!!" I mean : when I want to write a new app, I go towards New MFC Project, Select the type (Single Doc,...) and have a template to work on.
one more thing: You mentioned that you moved to .Net because it's easier. "I love the ease that I can create applications"
Could you tell me please how is it easier when there is not any editor for creating dialogs, any single doc or multiple doc template, however I found "form creator template".
Finally if you want the fact, the reason that I didn't move to Delphi when I started learning a Visual Language was that I hated Delphi, and that was one of the best reasons I selected VC++! Now!!
once again I appreciate you for your acswers and excuse me if my english is very bad!

There is an excellent editor for creating dialogs, they are called Forms now. You can have it act as a dialog by using ShowDialog() instead of Show() when you are ready to display it to the user.
Hamed Mosavi wrote:

.NET doesn't have this structure, however there is nothing to stop you from building it. You can create your own set of control classes that can operate like the old View classes and you can create your own document class to hold the data. However, you do have to do a little more work. But, since moving to .NET I've never found that I missed the old Document/View structure at all. In fact, I've found that the new flexibility that .NET offers to be much better as it doesn't constrain you into one way of thinking.

That's fine. I don't like Delphi either.
Hamed Mosavi wrote:

I'm not sure what the "Now!!" means at the end of that statement.

Your English is actually quite good - I've seen worse written by people who are supposed to have English as a first language.

Hi Mr. Colin Angus Mackay
Thank you so much , you gave me alot of very good information and ofcourse more confidence to move to .Net.It's extremely kind of you, and I can't find the appropriate world to express my thanks.![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)
For the last question in this conversation(from my side!!;P), could you tell me please, as you seems to have lots of experiences in .Net, witch language do you prefer?
Moving to C# and starting from the start!!, or moving to Managed code (or C++/CLI).
I must thank you once again for your nice patiance(you would be like to me now!!)
Best regards, Hamed Mosavi

Un belivable?
Did you know this?!!
 
Visual C++ has always been the best language for creating high-performance applications for Microsoft Windows and the World Wide Web.
This is from MSDN, while tring to compare programming languages!! (MSDN 2004, Programming Languages)
Is it tring to say that it's still the best one?

I think so, after all C++ is native language for Windows (at least current and previous versions). C++ apps of course beat apps written in managed languages in terms of execution spead; it beats VB, Object Pascal etc. (what else use to write win apps? Visual Prolog maybe ) as well.
You must imagine emphasis on high-performance  Personally, I'd use C++ in cases where is superior performance is needed (like processing HUGE data, calculations, 3D games...) and C#/.NET for Web Apps (ASP.NET is by far the best "tool" for web application I ever used) or Windows applications with classical UI. I find much easier and more efficient to do UI-oriented apps with .NET then with C++/WIN32API/MFC.

yes. When performance is issue #1.
just my 2 cents

Hi, everyone,
I have a question when I use the following code to get the response.
WebRequest req = WebRequest.Create(sURL);
try
{
WebResponse result = req.GetResponse();
}
catch(Exception){}
the code works very well on my XP, but when I run it under Windows server 2000, or some others PC, I sometimes get the exception:
The underlying connection was closed: The server committed an HTTP protocol violation.
it comes with the code GetResponse(). But when I use IE try the Url, IE works.
Would you please tell me why that is happened, and How to avoid/fix that, so I can read the response.
Thanks a lot in advance!!

Hello,
I have a problem with the PrinterSettings.Collate property I receive from a PrintDialog. It always seems to return false. I've tried it with a standalone application that does nothing but show the PrintDialog and return the Collate property afterwards. Is this a known bug, and if so, is there a workaraound for the problem?!
Thx klawipo

I have an application that communicates with the server program through a shared text file, located at a network directory. The server writes to the text file which my application reads. I am using FileSystemWatcher to monitor this file.
Now when server writes to the file, change event in my application fires after 2 or 3 seconds. However when I manually change this file and save it, it acts the ideal way. I want to reduce this time delay as this should act like realtime system.
My C# code goes like this :
-------------------------------------------------------------------
public MyWatcherClass()
{
watcher = new FileSystemWatcher();
this.watcher.Path = this.MyNetworkDrive;
this.watcher.NotifyFilter = NotifyFilters.Size;
this.watcher.Filter = this.MyTextFile;
this.watcher.Changed += new FileSystemEventHandler(OnChanged);
this.watcher.EnableRaisingEvents = true;
}
-------------------------------------------------------------------
What am I missing?
Thanks in advance

I remember asking this a while ago and getting an answer *cough* David Stone *cough*, but for the life of me I can't remember how to do it.
I have a Bitmap object, from which I can get the RawFormat. Is there a way I can get a friendly name, such as "JPEG", from the ImageFormat object without having to hard-code a lookup table or writing a clunky lookup function that enumerates the Decoders on the system? IIRC, you can do it in one line.
Thanks,

Hi,
I download the .NET Framework Version 1.1 Redistributable Package in the station, but when I try to run a .NET C++ application I got an error message
"Application has generated an exception that could not be handled."
The same application runs fine in my development station which has the full Visual Studio .NET installed. (It was ver. 1.0, but I also downlod the .NET Framework Version 1.1 Redistributable Package and SDK 1.1 as well).
Does anyone know what else I have to do to run the application outside of the development station?
Thank you in advance for your help.

I found out that I have to download NET Framework Version 1.0 Redistributable Package to run the application. After I did that, it works fine.

Depending on what your application does you might be missing a library assembly (DLL) needed, especially if you are getting the exception when the program is loading. Check the dependencies on your development machine. (If you build a deployment package using VS these any assemblies your application depends on should be packaged in the MSI automatically.)
If that's not it you might try adding an application thread exception handler of your own in an effort to get more information on just what exception is being thrown. For example, in your Main method (but before Application.Run()):
Application.ThreadException += new ThreadExceptionEventHandler(ApplicationThreadException);<br />
Then a simple handler:
static void ApplicationThreadException(object sender, ThreadExceptionEventArgs e) {<br />
string msg = <br />
"A problem has occurred while running CAPA Facilitator:\r\n" +<br />
"\t" + e.Exception.Message + "\r\n\r\n" +<br />
"Would you like to continue running CAPA Facilitator so that\r\n" +<br />
"you can save your work?";<br />
DialogResult result = MessageBox.Show(msg, "Unexpected Error", MessageBoxButtons.YesNo);<br />
<br />
if (result == DialogResult.Yes) {<br />
return;<br />
}<br />
Application.Exit();<br />
}<br />
This will display the exception error message in a dialog befor closing the program, which could provide clues to what's going on.
Hope this helps.

I try to buikd a strong name signed assembly in Jscript.net.
I am using the following assembly level attribute:
import System;
import System.Resources;
import System.Runtime.InteropServices;
import System.Reflection;
[assembly: AssemblyKeyFileAttribute("keyfile.snk")]
JSC does not complain at all, but the resulting DLL is not signed with a
strong name. Actually JSC does not complain even if keyfile.snk is missing.
CSC does the above job just fine but I prefer Jscript.NET for various
reasons.
SDK version is 1.1
Any feedback appreciated.

I have four questions regarding the following MSIL.
1. If auto is used, the layout of this object in the memory is decided by the runtime. What happens if I do not use auto?
2. How does ansi keyword help in handling interoperability between managed and unmanaged code?
3. What is the use of cil managed?
4. What is the use of specialname, rtspecialname and instance?
.assembly DemoMSIL{}
.class public auto ansi HelloWorld extends [mscorlib]System.Object
{
.method public hidebysig static void HelloWorld() cil managed
{
.entrypoint
ldstr "Hello World."
call void [mscorlib]System.Console::WriteLine(class System.String)
ret
}
.method public hidebysig specialname rtspecialname
instance void .ctor() cil managed
{
ldarg.0
call instance void [mscorlib]System.Object::.ctor()
ret
}
}
|
|
|
|

instance is used to indicate that the method is an instance method and not a static method.

To all,
Does anyone know how one can remove/reset the "Look In" history in the "Find in Files" dialog in the VS IDE? It is very annoying when I type in a wrong directory by mistake and it gets in the way forever.
Greatly appreciated.

I am using the openfiledialog in my project. Sample code: at bottom
I get a blank filename when I get a return back from the dialog.
This happens after I pick a file (any file).
Now when I run the same code on my other computer (laptop), it functions normally. What can cause this to happen?
I am not having any other system problems (that I know of), and this is really wierd.
Any ideas? (Framework 1.1) xp servicepack 2 ( I think I am fully upgraded software wise.)
If ofd.ShowDialog() = DialogResult.OK Then
'Load the excel import file into a datatable
PartsTrakCommonLibrary.PartTrakCommonLibrary.FillDataTableFromExcel(dtImportData, ofd.FileName)
End If
Thanks,
Foxjazz
