Any idea how EncryptPassword uses machinekey to encrypt the password. As per my knowledge Membership uses RijndaelManaged to encrypt/decrypt the password. How it provids key and IV hash to RijndaelManaged?

What I need to do is following:
I have saved password using Membership provider(.NEt 2.0) have to access the same from other site which is running on .NET 1.1 and not having Membership.

Appreciate your help.

What's this, even Google doesn't seem to find it. Have you tried the System.IO.Ports namespace?

As of how to accomplish this I wouldn't have a clue at the moment and I'm too lazy to google it

Retrieving variables from the main form, in a new form.

This problem is annoying me as it seems so simple, but I can't find a simple solution to it.
From my main form, called Form1, a new form, Form2, can be opened using the following code

Form2 options = new Form2();
options.Show();

But how do I refer to variables from the main form, in the new form? I have decalred them as public within the main form but can't figure out how to refer to them. I can easily do the opposite, and refer to values from within the new form, using 'options.<variable>' in the main form. But using Form1.<variable> in the new form does not work.

Thanks for any help.

You need to reorder the if conditions so that the AND comes first and use elseif. In the present state, the first two conditions are also true and that's why form1 and form2 get shown.

if(CheckBox1.Checked && CheckBox2.Checked)
  form3.ShowDialog();
else if (CheckBox1.Checked)
  form1.ShowDialog();
else if (CheckBox2.Checked)
  form2.ShowDialog();

This way, only if CheckBox1 and CheckBox2 are checked, form3 is shown.

Senthil

Hey guys,
I understand PrintDialog is a functionnality dedicated to Windows Forms.
Do you know a similar functionnality for Web Forms? Or am I wrong and could I use it for Web Forms?

how to store by ref parameter in object table/array?

Hi,

I have one problem I tryed to use method invoke to ...invoke some methods, in case I need to store by ref paramteter in object[] array, normally when I call MyFunction i set ref argument so it looks like that: MyFunction(ref MyObject) now I cant and if I set MyObject without ref argument it report me an error. Maybe someone has trayed to use tRfcInvoke in .NET SAP Connector to invoke RFC function with SAPTable as reference parameter or encounted this kind of problem in other projects?

Thanks in advance.

best regards,

Osin

Assuming you are using MethodBase.Invoke[^], the MSDN[^] documentation says that you don't need any special attributes for ref parameters.

"If the method or constructor represented by this instance takes a ref parameter (ByRef in Visual Basic), no special attribute is required for that parameter in order to invoke the method or constructor using this function. Any object in this array that is not explicitly initialized with a value will contain the default value for that object type."

Can you detect if a service is running?

I recently released a program that uses the WMI service. A small percentage of users had turned that service off for some reason, and as a result my app CTD'ed with no warning to the user.

I would like to be able to test that WMI is available, and if not warn the user about the need to activate it.

What's the best way to do this?

Your post is not specific. One way to interpret it is that you want to see what is running on other peoples computers... but that would just be a guess.

It's fairly simple to do, and you can even start it programatically if need be, here's a small snippet that starts a service not running (you'll need to add proper error checking).

string serviceName = "SomeServiceName";

ServiceController sc = new ServiceController();
sc.ServiceName = serviceName;

if (sc.Status == ServiceControllerStatus.Stopped)
{
	// Start the service, and wait until its status is "Running".
	sc.Start();
	sc.WaitForStatus(ServiceControllerStatus.Running);
}

A little more searching on the ServiceController class, and you'll see what else you can do with services.
