Hi Mwiseman96,

The error stack trace which you have mentioned is specific to the code which you have written and it seems there is some problem with the code which you have written and not with server or anything else. So there is no common specif solution.

"this.password = member.Password;"
In the above line of code, you are trying to use "this" operator which specifies the current object which invoked the function. Your error shows that "this" object is null and not having proper object instance assigned.
so try creating new object using "new" operator and call your function with reference to that object which your created.

example:
class test
{
public void funtiontest()
{
//new object created
test obj1 = new test();

//function is called with reference to the obj created
obj1.funtion1();
}

private void function1()
{
//your code where this operator references to the called object "obj1"
this.password = member.Password;
}

}

I hope this is helpful to you.
Thanks

For some reason the server that serves the page you are trying to access is not processing your request correctly. Could be a problem of cookies not accepted, or some other security settings, or a problem in the server.

When I trying to open the archive files, error "RRV Bucket is corrupted" is displayed. I am unable to solve this problem. can you please provide a solution. I understand data can be retrieved ,...


If this error occurs in a case where Shared Mail is being used, then first refer to the documents titled "'RRV Buffer Overflow' Error Message While Attempting to View a Mail Document" (#1093390) and "Using the OBJECT COLLECT Server Task to Manage Shared Mail Databases" (#1088860).

If the database is not in R5 format (ODS 41), then from a Domino 4.x server run Compact -M on the database. On a Domino 5.x server simply run Compact on the database. If updating the ODS to 41 does not resolve the issue, refer to the document titled "Database Has Grown too Large; Use File New Replica...' Error Occurs When Opening Local Database" (#1102305).

If none of the above resolves the issue, then where possible, a new replica should be made. If a replica is not available, restore the database from a backup, if one exists.

Supporting Information:
Corruption can be caused by many things, but a possible cause for the error in this case was that a third-party application had altered the physical location of the database on the hard disk, resulting in the Record Relocation Vector table being incorrect and the information not being located. This has been reported to happen with customers using a disk defragment utility while Compact is running.

Can't download drivers. http://h20180.www2.hp.com/apps/Lookup?h_lang=en&h_cc=us&cc=us&h_page=hpcom&lang=en&h_client=S-A-R163-1&h...


I just tried to get to the HP site from 2 machines, and they both failed as well. I download drivers from this site regularly, so the problem is that the HP support website is down. I don't think this is a problem with your computer or browser - it's an HP website problem. Give it some time, usually big websites like this don't stay down for very long.

An unhandled exception has occured .......


An attempt was made in a program or script to use an object before creating the object. For example:

dim SomeObject as Object
SomeObject.attribute = "string value"

will generate thie error message because the SomeObject that is being referred to has not been created. For this, we need the New keyword:

dim SomeObject as New SomeObject
SomeObject.attribute = "string value"

will run without errors
