Hey everyone. I've been out of the programming world for a number of years and would like to upgrade my knowledge. I don't need tutorials regarding how to program, per se, but rather an overview of the strengths/weaknesses of the differing languages.
I'm new to the whole .net and C# world but have a strong understanding of programming principles and language structures, etc. I've worked with MFC in older versions of Visual Studio, although only in C++. I havn't touched VB since the mid '90s but if it has improved I'm not adverse to giving it another try.
Where should I go to find good overviews of .net and C#, as well as changes to the visual studio interface?
Thanks - mutty

Hello Everybody:
In somewhere I read that with the tool cl.exe that comes with .NET Framework 1.1 is possible to compile standar C or C++ code.
So I tried to compile the classical example code.
Lets name it as hello.c.
Here it is the content of the source:
------------------------
#include <stdio.h>
int main(void)
{
printf("Hello\n");
return 0;
}
-------------------------
But when I enter in the command line:
F:\>cl hello.c
This is what I see on console:
---------------------------------------------------------------------
Microsoft (R) 32-bit C/C++ Standard Compiler Version 13.10.3077 for 80x86
Copyright (C) Microsoft Corporation 1984-2002. All rights reserved
hello.c
Microsoft (R) Incremental Linker Version 7.10.3077
Copyright (C) Microsoft Corporation. All rights reserved.
/out:hello.exe
hello.obj
LINK : fatal error LNK1104: cannot open file 'LIBC.lib'
------------------------------------------------------------------------
Thats all!: I got only the object file but not the executable.
I checked that LIBC.lib does exist in F:\Archivos de programa\Microsft Visual Studio .NET 2003\Vc7\lib and my LIB enviroment variable is set to that PATH.
Somebody could tell me what I am doing wrong?
Am I missing something?
I will appreciate any help.

I think your lib files need to be specified on the command line.

Ensure you're launching cl.exe from your 'Visual Studio .NET 2003 Command Prompt', in the start menu (this may be translated!) under Visual Studio .NET 2003 > Visual Studio .NET Tools. Alternatively, run vsvars32.bat in %ProgramFiles%\Microsoft Visual Studio .NET 2003\Common7\Tools.

Christian and Mike, thanks to both for the answers.
I have installed the .NET Framework 1.1 runtime and SDK and not the Visual Estudio .NET 2003 IDE.
I have discovered that now I can't recompile others standard sources in C++ that a month ago I was able to compile without problem. Now I got the "LINK: fatal error LINK1104: cannot open file LIBC.lib". I am suspecting that the file LIBC.lib has become corrupted for something ocurred in the meantime.

Hi, there's something that really irks me with my Form application (using mc++; hope that doesn't matter)... When I start my app, there is a small delay such that it shows my form with no widgets at a very small size (about the default size when creating a Windows Form Project in VS.NET), then quickly resizes to the size the form should be, and places the widgets... It does this very quickly, but it's still noticable and very annoying... Anyone know why it is doing this and how I might fix it...???

Hi everybody
-) How a Windows Service intracts with a program( application ) and how a application use a service ?
|

Applications can interact with services via .NET remoting, you'll find a lot about it on MSDN.

Hi all,
I want to record MenuItem click event at before the event is processed by using below code
BindingFlags all = BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.FlattenHierarchy;
PropertyInfo eventsProp = control.GetType().GetProperty( "Events", all);
EventHandlerList handlers = (EventHandlerList) eventsProp.GetValue( control, null );
FieldInfo field = typeof(Control).GetField("EventClick", all);
object value = field.GetValue(control);
handlers[value] = Delegate.Combine(eventHandlerToBePutAtStart, handlers[value]);
This work fine with Control type but not with MenuItem  I just know that the FieldInfo return from :
FieldInfo field = typeof(Control).GetField("EventClick", all);
is null. Why is that ?  Please help me!
Thank in advance!

MenuItem does not have Control as base class, so typeof(Control).GetField("EventClick", all) ain't gonna work.
How about FieldInfo field = typeof(MenuItem).GetField("EventClick", all);?
Hope this helps!

Thank you for your reply!
I tried it as you said but got nothing.
Here is my code:
private static BindingFlags flags = BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.FlattenHierarchy;
private static FieldInfo EventKey( string name, Type type )
{
FieldInfo key = type.GetField( "Event" + name, flags );
if (key != null)
{
return key;
}
key = type.GetField( "EVENT_" + name.ToUpper(), flags );
if (key != null)
{
return key;
}
if (name == "TextChanged")
{
key = type.GetField( "EventText", flags );
}
if (key != null)
{
return key;
}
if (type == typeof(object))
{
return null;
}
return EventKey( name, type.BaseType );
}
public static void Main()
{
FieldInfo field = EventKey("Click", typeof(MenuItem));
if (field != null)
{
Console.WriteLine("Got it");
}
else
{
Console.WriteLine("Nothing");
}
Console.ReadLine();
}

well did some diggin' in the MenuItem class with reflector, and i think here's the thing:
MenuItem has a friend class called MenuItemData. MenuItem also has a private variable of type MenuItemData, called data. MenuItemData has a private EventHandler called onClick, and i think thats the one you're after.
Here's a function i put together (it's in VB.Net though):
Private Shared Function GetMenuItemClickEvent(ByVal item As MenuItem) As EventHandler
If (item Is Nothing) Then Return Nothing
Dim allflags As BindingFlags = BindingFlags.Instance Or _
BindingFlags.Public Or BindingFlags.NonPublic Or _
BindingFlags.Static Or BindingFlags.FlattenHierarchy
'Get the MenuItemData from the MenuItem
Dim data As Object = item.GetType.GetField("data", _
allflags).GetValue(item)
'Get the onClick EventHandler from data
Dim clickevent As Object = data.GetType.GetField("onClick", _
allflags).GetValue(data)
If (clickevent Is Nothing) Then
'No method is linked to onClick, so onClick is null
Return Nothing
Else
Return DirectCast(clickevent, EventHandler)
End If
End Function
Cheers!

Thank you very much!
It realy work fine! I don't know about MenuItemData object before!
|
|
|
|
|
You're welcome!
I never knew of the MenuItemData thingy too, just shows how handy some peeking in the .Net Framework is!
|
|

|

Just one more note!
After getting event handler of MenuItem click event, to use Delegate.Combine for adding new user defined handler to process this event, must do like this:
object data = menu.GetType().GetField("data",flags).GetValue(menu);
FieldInfo eventField = data.GetType().GetField("on" + eventInfo.Name,flags);
MulticastDelegate handler = (MulticastDelegate) eventField.GetValue(data);
if (handler != null)
{
handler = (MulticastDelegate) Delegate.Combine(handler,recorder);
eventField.SetValue(data,handler);
}
My program now works fine!

I use System.Windows.Forms.DataGrid to display an ArrayList of objects. DataGrid allows nested navigation to other object's properties if they are of type ArrayList.
My problem is, that I cannot determinate, which object is being displayed after navigating to deeper objects. The DataSource of the grid is still "root" ArrayList of objects, I cannot determinate which ArrayList property of the "root" object is being displayed after clicking on navigation.

We have some code ( c#, asp.net codebehind ) that we use to translate small amounts of text between languages. It's pretty simple. We post the text to translate to google and then parse the return HTML stream to get the translated text. All was well until we needed to add chinese to the list of translated languages. I assumed the return from google would have the translated chinese in unicode. So we parsed out the unicode that represents the returned chinese and used the code:
// note: UniResponse contains the byte entries for the returned chinese only
UnicodeEncoding Unicode = new UnicodeEncoding();
int charCount = Unicode.GetCharCount(UniResponse, 0, UniResponse.Length);
char[] chars = new Char[charCount];
Unicode.GetChars(UniResponse, 0, UniResponse.Length, chars, 0);
string s=new string(chars);
This should get the byte stream back to a string type I could add to the dynamically created HTML for the new page. But when our page is displayed, it does show some chinese chars/words/whatever, but they do not match what google shows. We verified we do indeed parse out the correct bytes from the returned HTML. All the samples I could find on CG only translate with the english char set, they all seem to stop short of non-english char sets. When using unicode, I don't have to worry about codepages or anything do I?
If anyone knows of an example or has some words of wisdom concerning the translation process. Please let me know.
TIA

I have a custom combo box that is data bound to the SelectedValue property.
Everything works fine, but I have a ReadOnly property in the control, which makes the CB invisible, and a read-only text box shows up in it's place.
When it's in this mode, the SelectedValue property stops being updated from the data binding.
This has bugged me for a few days, and any help would be greatly appreciated 
Brian

On tinkering around with it, it seems only to not work when you make the control invisible before you do your first data adaptor Fill method.
If you do the fill, then make it invisible, everything works fine from there on out. You can make it visible, invisible again, etc.
Odd.

Hi all,
I am facing a problem where I am not able to get the path of directory in Linux. I want to install a software using Oracle as database in Win2000. The database is on a Linux system. In this system I have created a shared folder "shared". Then I give this path during installation. The setup runs successfully but the .ora files which are created are not in the folder specified (shared) but in another folder with names C:shared|name of the file.ora. The setup.inf file on the system where the setup was run shows the path as "C:\shared". There is no such drive in Linux.
Can anyone tell me what is the actual problem and how to fix it.
Regards,
Harshad
