I have finally discovered that the Deployment project in Visual Studio .NET offers a GAC folder. I have just, when creating my deployment project, to place my assemblies in this folder.
And now, I have another question: I would like that the setup program make the assemblies appear in the Visual Studio .NET "Customize Toolbox" dialog box. How to do that?

Hi. Can you please tell me what the AutoEventWireUp is for? I've read the explanations in SDK but I couldn't understand what it does.

I know you can make web-references dynamic, which then only need a small change in the web.config file to repoint them to the new location you want to look at.
My question is, can you do something aking to this with regular (non-web) references? Perhaps using the web/<application>.config file, or a manifest file or something?
We are looking to create a central library directory where we can keep our common libraries for access from any machine which needs them. One consideration was 2K's Distributed File System, but that is an awful lot of complications, especially since it means getting our domain administrators involved. So i was thinking there might be an easier way by being able to just put in a line which tells the app where to look for the reference at run-time. yes??
Thanks in advance.

There is a way of doing this with regular refrences though you are required to use reflection to dynamically load the assembly you are looking for.
Have a squizz here http://msdn.microsoft.com/library/en-us/cpguide/html/cpconhowruntimelocatesassemblies.asp[^]
It would probably be eaiser to just setup a network share for the library, and add a project reference. I think deciding which asseblies to use at runtime is most suited to situations where you know the interface but you want the freedom to decide which assembly you will use to implement that interface.

That sounds about right.
I would just point out that assemblies run from a network share will have reduced permissions when using the default security settings for .NET. Depending on what your assemblies do, you may need to alter these settings to give your assemblies the necessary permissions.

Sorry for the long post, but I need some help. I'm writing a class that implements IComparer, and I'm having some problems. What do you make of this:
My class looks like this:
class RandomComparer : IComparer
{
private static Random c_random;
private static RandomComparer c_instance;
public static IComparer Default
{
get {return c_instance;}
} // End Default
static RandomComparer()
{
c_random = new Random();
c_instance = new RandomComparer();
} // End RandomComparer()
int IComparer.Compare(object objA, object objB)
{
// Are the objects different?
if (Comparer.Default.Compare(objA, objB) != 0)
{
// Get two random numbers.
int numberA = c_random.Next(0, m_maxSample);
int numberB = c_random.Next(0, m_maxSample);
// Compare them and return the results.
if (numberA > numberB)
return 1;
else if (numberA < numberB)
return -1;
} // End if the objects are not the same.
return 0;
} // End Compare()
} // End class RandomCompare
I use this class to sort an array like this:
string[] someArray = new string[] {"item 0", "item 2", ... "item N"};
Array.Sort(someArray, RandomComparer.Default);
Everything works fine most of the time, but every now and then the framework throws an exception that says:
"An unhandled exception of type System.ArgumentException occured in mscorlib.dll
Additional information: IComparer (or the IComparable methods it relies upon) did not
return zero when Array.Sort called x.CompareTo(x). x: value 7 x's type: String
The IComparer: RandomComparer"
If I set Visual Studio.NET to break for all exceptions, I get a different exception, this time it says:
"A first chance exception of type 'System.IndexOutOfRangeException' occured in mscorlib.dll
Addition information: Index was outside the bounds of the array."
If I elect to continue debugging in this case, the framework then throws the first exception.
I searched the Microsoft knowledge base, and did a Google search, but I couldn't find anything.
Sheesh! This should be a five minute programming task, but I've worked on this all morning long! 
Has anyone ever run across this? Does anyone have any ideas?

OK, either my original post was too long for anyone to read or I'm the only person having this problem. Let me simplify things. Has anyone noticed flaky behavior from .NET when creating or using a custom IComparer? I'll probably submit this to Microsoft support, but that will take forever... In the meantime, has anyone run across this sort of problem?

Hi, Martin.
Most sort algorithms need stable comparison functions. Your function seems to be returning random results when the objects are different, so the .NET framework gets lost.
Suppose you have created a function where A > B > C > D. Your IComparable should be stable and NEVER return B > A > D > C.
Comparison is, too, a transitive function. So, if A > B and B > C, you can safelly assume that A > C. Your function does not guarantees that.

Hello everybody,
I've dome some research for an Open Source DataGrid component for .NET but I couldn't find anything worth working with. What do you think of starting up a new project for a suite of Data-aware components that could be comparable to commercial ones?
Is there anybody interested on talking about that?

Anybody know if the functionality of the discretionary access control lists is in the .NET managed framework anywhere --- i.e. can I programatically add or remove user permissions for a given shared printer without getting down and dirty with the API?

I've heard that some of these features can be found in the System.Management namespace. I have personally found it easier to just wrap the pertinent SDK calls using PInvoke. I seem to recall reading an article or two related to WMI and PInvoke/DACL stuff on this website. Try doing a search.

Can anyone explain to me why the text retrieved from a mutli-line textbox has CRLF instead of LF for new lines? And can I alter this behaviour?
I thought we'd seen the last of the whole dos vs unix thing
|
|

Well I guess a simplistic replacement strategy would be:
using System.Text.RegularExpressions;
...
someTextBox.Text = Regex.Replace(
myMultiLineString, "\n", "\r\n" );
and vice versa for reading text from a TextBox.
Does seem rather ugly to me though.

I have created a Windows Form control and also an application that uses it.
When I reference the control, if I don't choose "copy local = true", the it throws a System.IO.FileNotFoundException.
What may be the reason?

Is the directory that contains the assembly in your search path? Your executable will need to be able to load the assembly at runtimne...
|
|
|
|
|
Yes, you are right...
In fact, the correct place for this assembly would be the GAC (Global Assembly Cache). However, I don't know how to tell my setup program to place the assembly into the GAC. (I am creating a Deployment Project)

Does anyone have any source examples that can read the metadata from a PE file? I have Serge Lidin's book _Inside Microsoft .NET Assembler_, but there seems to be a few errors in it, and some of the descriptions are a bit confusing.
Any help would be appreciated,

Has anybody had any problems with the included version of Crystal Reports for Visual Studio after upgrading to VS.NET 2003/.NET Framework 1.1?
It seems like it's not liking to use a DataSet as a ReportSource anymore. If I go back to 2002/1.0 everything works just fine.

I'm running on Visual Studio.NET 2003. Is there a quick way to implement an interface via a keystroke or menu option? Some of the interfaces in .NET have many member that need to be implementented, so what I'm looking for is some sort of keystroke or menu option that will fill in empty functions for all the members that need to be implemented.
Thanks in advance.

OK, I figured out how to do this, but for some reason, the 'Implement Interface' is not on the context menu. Any ideas why?
Again, thanks in advance.

Is there any tracker rect in .Net WinForms (like CRectTracker in MFC) ?

Hi,
I need to access a particular .NET Windows Form DLL as ActiveX Control.
<OBJECT id="myControl1" name="myControl1" classid="PrintCtrl.Dll#PrintCtrl.Class1" VIEWASTEXT width="0" height="0">
< PARAM NAME="File" VALUE="http://localhost/" >
</OBJECT>
Now that this Dll needs to access and print from IE, I had to package as CAB file using VS.NET Setup and Deployment Project (CAB Project). Instead of DLL, I gave PrintCAb.cab. But now it is saying 'Object does'nt support this property/method'
How to refer the methods in the DLL if I give this CAB now?
Please advise...

I was wondering what kind of memory I use when I, for example, declare a new variable... Is it Ram, or disk swap? Do I have any control over that? Can I find out how much free memory a system has?
Thanks,

When you declare a variable it gets created in RAM. If your available RAM is low then the system might swap some stuff to disk in order to free up some RAM, but even in that case your variable would stil reside in RAM. As far as I know you really don't have much control over that.
