On a web page from Microsoft I discovede that .Net 1.1 SDK cannot be installed on a 64 bit processor(http://msdn.microsoft.com/netframework/technologyinfo/sysreqs/default.aspx[^]), but on the main download page it is not mentioned.
Can enybody confirm that on an 64 bit architecture the sdk can not be installed (or it doesn't work)?
I hope we understand...because is a rough world out there...

I guess it depends on which of the 64 bit platforms you're using, IA64 (Intel Itanium) or x64 (AMD). You can install and run the SDK on x64 just fine, as the platform supports running 32 bit applications natively. Win64 might run it on WoW, but it still will run fine.

Well, VS 2003/.NET 1.1 will certainly run on an AMD 64 machine. That's what I'm using at the moment.

The BindingList<t> class is not serializable, but the List<t> Items are. Does this seem strange to anyone else? Since Items are protected, can anyone help me understand how to implement a Serializable BindingList? Thanks.

Thanks to Mav in the C# group, here's the answer:
///
/// The item list, used for Serialization.
///
[XmlElement(Type = typeof(<t>), IsNullable = true)]
public ArrayList ItemCollection
{
get
{
ArrayList alist = new ArrayList();
foreach (<t> item in this.Items)
{
alist.Add(item);
}
return a;
}
set
{
ArrayList alist = value;
foreach (<t> item in alist)
{
this.Add(item);
}
}
}
You'll need to change the <t> to your specific type, since the serializer doesn't generic.
Have fun.

Hi Folks,
I got a Wrapper Dll around a native C++ static library. In .NET 1.1 this
worked fine. When moving to .NET 2.0 I get a couple of unresolved externals /

In my .NET 1.1 Project I had to make the following Linker Settings to build
the DLL:
1.) Additional Dependencies: mscoree.lib msvcrt.lib (or msvcrtd.lib for
debug version) mystaticlib.lib
2.) Ignore Specific Library: nochkclr.obj
3.) Force Symbol Reference: __DllMainCRTStartup@12
In my Wrapper Classes I had to add the following:
#using <mscorlib.dll>
using namespace System;
using namespace System::Runtime::InteropServices;
This does not work any longer with the new Visual Studio and the new .NET
Framework.
The only article that I was able to find on this subject:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvs05/html/TransGuide.asp
Doesn´t mention Linker settings at all.
Could anybody please help me or tell me where to go for further reading?
Thanks in Advance for your efforts.

Hi there,
didn't know where exactly to post this. Hope it's ok here.
I'm just wondering, whether there is a possibility to include/exclude files in different build configurations. Say in Release config, I'd like to distribute this set of *.sql, *.txt and *.config files and in Debug config, there are just different files to go. Any ideas?
Any help is greatly appreciated.

Hi All,
I've tried to add the UrlEditor window to a property for a custom control I created.
Here is my code :
[
Category("Data"),
Description("URL associated with the link."),
DefaultValue(""),
EditorAttribute(typeof(System.Web.UI.Design.UrlEditor), typeof(System.Drawing.Design.UITypeEditor))
]
public string urldata
{
get
{
return urlData;
}
set
{
urlData = value;
}
}
Then, when I use my custom control, I have the urldata property, I can write any string I want into it, I also see the "..." button at the right, but nothing appears when I click on it.
What did I wrong ? Why does this UrlEditor not show up ?
Thanks ! Stéphane.

Hi all,
Im looking for a way (.net or not) to monitor file access and permit access to certain application to it...
I want to be able to get an event saying (this file) tries to do "this" to this file
Acess - Deny
Thanks

You can check out FileMon on www.SysInternals.com. It uses a custom .DLL to do something very similar. There's no source, but there is a discussion of how it's done. Be warned, it requires a black-belt in NTFS Internals to write it...

Anyone know a straight foward way to insert a string at the beginning of a text file that already has data in it? I thought there was an insert function in the StreamWriter, but apparently not.
For my purpose, the insert will always be at the beginning of the file and it doesn't matter if the first line is overwritten or not.
Thanks,
RABB17

Figured it out. It was in the FileStream, not the StreamWriter. If anyone ever needs to do this:
System.IO.FileStream f = SupportClass.RandomAccessFileSupport.CreateRandomAccessFile(MyApp.playFileName, "rw");
int fileLength = f.Length;
line = "This is written in front of this many characters: " + fileLength.ToString();
f.Seek(0, System.IO.SeekOrigin.Begin);
//insert blank line at top of file
SupportClass.RandomAccessFileSupport.WriteBytes("/n", f);
//return to top of file
f.Seek(0, System.IO.SeekOrigin.Begin);
SupportClass.RandomAccessFileSupport.WriteBytes(line, f);
//return to end of file
f.Seek(f.Length, System.IO.SeekOrigin.Begin);
f.Close();

Yeah, to do a true insert of text into the file, you must rewrite the entire file. There's no other way to do it.

I am running into a very frustrating problem with an application which works with threads.
Basically, what I am doing is creating a number of threads which I use for executing procedures. I cannot use the thread pool as the application does not suit itself to that sort of methodology (I will need to have greater control over the individual threads). For this reason, I am creating threads and keeping them around until I need them and then using them as needed.
Anyway, what I am seeing is that, if I have my threadStart procedure use a "while not terminated" type loop, the thread takes up lots of CPU time. For example, here is the ThreadStart:
private void doSomething()
{
while (fKillThread != true)
{
doSomethingElse()
System.Threading.Thread.CurrentThread.Suspend();
}
}
In theory, this should run ONCE and then suspend itself and take no further CPU time. However that is definitely not the case. Instead, these threads peg the CPU at 100%. It is almost as if it is continuously evaluating the while condition instead of doing it once and suspending.
So, why does .NET Thread.Suspend() not actually put the thread to sleep until it is called inside of a while loop?
If I eliminate the while loop and just call suspend(), it suspends and takes no CPU time at all.
Can anyone shed some light on what is going on here?
thanks
[edit]
I found this post that looks like the same thing is happening:
http://www.highdots.com/forums/visual-studio-net-debugging/thread-suspend-causes-100-cpu-2194189.html
this was from back in 2003 - anyone know if it was ever fixed or is .NET threading just broken until I upgrade to 2.0? Is it fixed there???

I checked you code in 2.0. Besides the fact that Thread.Suspend() is Obsolete is working fine and you have no CPU penalty.
|
|
|
|

thanks for the check. While I'm not sure when we'll officially move over to 2.0, it's good to know that when we do this issue will no longer be a problem.
You say that Thread.Suspend() is obsolete - what is the new methodology for suspending threads? Do they recommend you create/free them all the time (Im going to have potentially LOTS of processes, so I figured this would be a lot of overhead).
I know I can avoide using suspend() and instead switch over to events, but is there a new and improved thinking on this for the 2.0 world?
thanks again

If you have to use 1.1 try to set your thread as background one.This may eliminate the cpu consumption inside the loop.just a thought.
|
|
|
|
|
Based on the link you gave, it looks like Thread.Suspend is buggy. How about using some other mechanism to suspend and wakeup threads, like ManualResetEvents, for example?

Hello,
I've created a subclass of the Button class and I can't figure out why my OnPaintBackground method never gets called. Have any of you ever encountered this problem?

I figured it out:
this->SetStyle(ControlStyles::Opaque, false);
Just FYI...

from MS:
The PInvokeStackImbalance managed debugging assistant (MDA) is activated when the CLR detects that the stack depth after a platform invoke call does not match the expected stack depth given the calling convention specified in the DllImportAttribute attribute as well as the declaration of the parameters in the managed signature...
ok, understood, by my code is:
Friend NotInheritable Class NativeMethods
Private Sub New()
End Sub
Declare Function GetKeyState Lib "user32" Alias "GetKeyState" (ByVal _
nVirtKey As Long) As Integer
End Class
Now, how should I change the parameters to match those MDA is looking for?!?
Already tried to disable MDA via registry, but I think a solution is not covering an error ...
Thanks in advance /// Angel

I've found!I was sure that nVirtKey was a Long, but It's a Short (MSDN[^])
sorry ...
