I'm curious if anyone has found a way arround it. I've got a dll built with the beta of c# VS.Net 2005. I want to add that dll as a reference in a vs.net 2003 project but i get the classic "could not be added. this is not a valid assembly or COM component. only assemblies with extension 'dll' and COM components
can be references. Please make sure that the file is accessible, and
that it is a valid assembly or COM component." error.
anyone found a way arround this, or am i trying to do the impossible?

There's a good chance you're trying to do the impossible, since the 2005/.NET 2.0 dll may have references to or exposes 2.0-specific functionality (such as generics) which are not supported in 2003/.NET 1.1.

The problem is even more straight forward than that. Because 2.0 introduced such items as generics it required the Metadata format to be updated. This new format is not backwards compatible with 1.0 and 1.1. Such the 1.x versions of the frameworks cannot load your 2.0 dll irrespective of what type of code you actually wrote in the dll.
However it is possible fon a 2.0 DLL/APP to reference a 1.x DLL

Is there a way to determine whether an installed print driver (as shown in PrintDialog) is for a printer or a fax? PrinterSettings doesn't seem to provide that kind of information.

Okay, not sure on this, but give it a shot. (I don't have a fax hooked up to any printer....) Put the following in a Console Application and run it to see if you get what you want. If a "printer" is fax capable, then hopefully you will see it in the CapabilityDescriptions property. You need to add a reference to the System.Management.dll in your project.
ManagementClass c = new ManagementClass( "Win32_Printer" );
ManagementObjectCollection moc = c.GetInstances();
foreach( ManagementObject mo in moc )
{
string name = ( string ) mo.Properties[ "Caption" ].Value;
string[] desc = ( string[] ) mo.Properties[ "CapabilityDescriptions" ].Value;
Console.WriteLine( "{0}", name );
foreach( string s in desc )
{
Console.WriteLine( "\t{0}", s );
}
Console.WriteLine();
}If you don't see "Fax," or something like that, then iterate over all the properties of the ManagementObject and see if you can find something in there.
Hope it helps.

Thanks Curtis. I need something more "robust". though. There is no capability listed for a fax driver and I can't use the driver/printer name because of localization issues (the app should be designed to work in other countries, as well).

Any other ideas? I've also tried Win32 API EnumPrinters with no luck.

sorry, cant get my brain working this morning.
the logical question I need my program to figure out is :
The X day of every Y month(s) with a Startdate of Z and a (Enddate of W OR occur V times)
this is my start:
<code>string matchpattern2 = "(0[1-9]|[12][0-9]|2[08])";
Regex re2 = new Regex(matchpattern2);
if(re2.Match(monthly1TxtBox1.Text.ToString()).Success == true)
{
int intDays = 0;
TimeSpan tsWeekly = endDateTime.Date.Subtract(startDateTime);
intDays = tsWeekly.Days;
DateTime[] datearray = new DateTime[intDays];
for(int x=0; x<intDays; x++)
{
datearray[x] = startDateTime.AddDays(x);
}
Array.Sort(datearray);
//DoTheWork
}</code>
anyone experienced with doing something like this?

What are you trying to do? Skimming over your code (use pre tags next time), I can't make out from your code what you're trying to accomplish.

sorry, basically all i've done so far(in the code i posted) is make an array of DateTime's between the start and end date.

I think I figured out my issue. Here is my code for anyboday else that needs to do the same.
int dayOfMonth = Int32.Parse(monthly1TxtBox1.Text);
int iterativeMonths = Int32.Parse(monthly1TxtBox2.Text);
string matchpattern2 = "(^1?[1-9]$|^[1-2]0$|^2?[1-8]$)";
Regex re2 = new Regex(matchpattern2);
if(re2.Match(monthly1TxtBox1.Text.ToString()).Success == true)
{
int intDays = 0;
TimeSpan tsWeekly = endDateTime.Date.Subtract(startDateTime);
intDays = tsWeekly.Days;
DateTime[] datearray = new DateTime[intDays];
for(int x=0; x < intDays; x++)
{
datearray[x] = startDateTime.AddDays(x);
}
Array.Sort(datearray);
int loopcounter = 0;
int intRecur = 0;
if(occTxtBox.Text.Length > 0)
intRecur = Int32.Parse(occTxtBox.Text.ToString());
int occurNum = 0;
for(int x=0;x < intDays;x++)
{
if(intRecur == 0)
{
if(datearray[x].Day == dayOfMonth)
{
if(loopcounter == 0)
{
//DoWork
loopcounter = loopcounter + iterativeMonths+1;
}
else if(datearray[x].Month == startDateTime.AddMonths(loopcounter).Month)
{
//DoWork
loopcounter = loopcounter + iterativeMonths;
}
}
}
else
{
if(datearray[x].Day == dayOfMonth && occurNum < intRecur)
{
if(loopcounter == 0)
{
//DoWork
loopcounter = loopcounter + iterativeMonths+1;
occurNum++;
}
else if(datearray[x].Month == startDateTime.AddMonths(loopcounter).Month)
{
//DoWork
loopcounter = loopcounter + iterativeMonths;
occurNum++;
}
}
}
}
msg.Text += "<font color=red>Task Added</font>";
posAddEdit = 0;
}
else
{
msg.Text = "<font color=red>Please enter a day between 1 & 28</font>";
}
p.s. pre /pre always eats my for loops

I am not quite sure what your regular expression is supposed to match on.
0[1-9] matches 01 through 09.
[12][0-9] matches 10 through 29.
2[08] matches 20 or 28. This is already covered by previous.
Do you want it to be 3[0-8]
Also, as it is, this RE will match number in a larger string. For instance, the following string will match on the 20:
34562055
If you only want two characters, try:
(^0[1-9]|[12][0-9]|2[08]$)

Have you tried using System.Diagnostics.ProcessStartInfo? With that, you can supply a user name & password through code, but I don't know if this will work for UNC shares.

You can try Judah's suggestion. I don't know if it'll work either.
But, if it doesn't, a workaround I know of would be to temporarily map a drive to the share. You can most definately supply the username and password to that.
But, to clarify, there is NO WAY to get around that login box. The machine your connecting to wants to know who is trying to get into that share. That target machine doesn't trust the credentials that your app is running under. There is simply no way of getting around that. But, if the credentials are supplied using a different method, that box won't show up.

Thanks both of you.. I am off from work now.. will try Judah's suggestion tomorrow.
Dave what credentials are you talking about.. can you please elaborate a bit more.. Let me be more precise. I have an application running on Windows XP Professional trying to access a shared file located on a network drive which is running Windows Server 2000. What's that "other method" Can you elaborate?
Thanks

The credentials you used when you logged into Windows on your machine...Username and password. When you try to connect to another Windows machine, those credentials are sent to the remote machine.
If that machine isn't a member of the same domain (if you have one!) as your machine, then it has to rely on its own user accounts to authenticate you. If your username doesn't exist on the remote machine, it'll ask you for an account and password that it knows about, because it doesn't trust the account information it's getting from your machine.
Now, you only have to log into a remote machine once and it'll remember who you are for as long as you are logged into your machine. There are many different ways to get an authenticated connection to a remote Windows machine. The most common is mapping a drive letter to a share on the remote machine. You have to supply a username and password to the remote machine if it doesn't trust you. Since you can't just connect to a remote share without first authenticating to the remote machine, you need to authenticate an account with the remote machine. You can't do that by just connecting to a remote share. There's no way to enter the account information. But, you CAN do it through code if your code maps a drive to the share first. You have to supply the function For example...[^]
