You've probably used some run-time library that you have on your computer but isn't on the server.
To check dependencies for a DLL, get hold of Dependency Walker[^].
If you have built a Debug build of your DLL, I recommend building a Release build and testing that on your computer before deploying that to the server.

I have build the release one and tested it on my local computer and it is working , and for information i did not use any external library just the standered one , and i still have the problem

If your DLL was built using Visual C++ .NET 2002 or 2003, and you opted to use the multithreaded DLL version of the C runtime library, there's a new version that may not be on the server.
For 2002, you need msvcr70.dll; for 2003 it's msvcr71.dll.
If you've used any C++ standard library features (for example, iostreams) you might also need msvcp7x.dll. If you used 'old' iostreams (declared in <iostream.h> rather than <iostream>) you'll also need msvci7x.dll.
Even if you only used Visual C++ 6.0 to compile, the server might not have all the required C runtime DLLs, although this is less likely. Windows NT 4.0 did not originally ship with msvcrt.dll version 6.0, but it's included with SQL Server 2000.
I still recommend using Dependency Walker to view the actual DLLs required by your DLL. Using it on the server will show what's missing.
The other possibilities I can think of are that you've specified the wrong DLL name - although I would expect that you'd noticed this - or that the DLL is in the wrong directory. You may be able to specify a full path - I haven't tried this.

Is it possible to script a dts package the way one can script an sp? I was thinking that running the script through query analyser might help me discover exacly where the package is failing in copying the larger of our 3 db's to our disaster recovery server, but I haven't managed to find an option (other than saving as a VB file).
Thanks again

Hi,
I've the following requirements:
1) Allow users to edit columns 2 & 3 of a DataGrid.
2) Prevent users from adding rows.
I can solve (1) by checking the event of moving cells, and then doing the following:
---------------------------------------------------------------
if (this.DataGrid1.CurrentCell.Columnnumber==0)
this.DataGrid1.ReadOnly=true;
else
this.DataGrid1.ReadOnly=false;
---------------------------------------------------------------
This works really neatly. I can't figure out how to solve problem (2) though.
Any ideas?

IIRC, it's a property on the underlying DataView: AllowNew.

Thanks Mike, this does the trick.
I somehow need to set this each time the control becomes active, but still, it works nicely.
thanks,

Could you please give me some website that can help me while migrating SQL to Oracle?
|
|
|
|

Oracle has a tool to migrate from SQL Server, I read about it in otn.oracle.com[^], but can't find the link.
Do some search in there.
Free your mind...

Do in-memory database systems such as Prevayler or commercial products have a user-specifiable number N, such that if the system uses more than N bytes of RAM, the system will use virtual memory? That way the database system would use the operating system's virtual memory smarts for managing what goes on disk and what goes in memory, while providing the ability to have a larger database than just what will fit in available RAM.
|
|
|
|
|
I'd expect that such products (at least Bamboo Prevalence) will use virtual memory when necessary, as Windows may allocate more memory than the RAM available when an application asks for it.
As for setting the limit for when virtual memory will be used, Bamboo Prevalence does not expose such a setting. Maybe the OS will let you set such limits...!?!?
Have a look at my latest article about Object Prevalence with Bamboo Prevalence.

I'm wondering if it's possible to stop a SQL database from running, from within a DTS package? It's essential that the SQL Agent keeps running on the machine however.
Thanks for any info

Hmm. I've never even tried running the SQL Agent without the server itself, but it will probably work.
If all you need is to make the database unavailable, you can do it in a few ways without actually shutting down the server. You could call sp_detach_db. Even better, you could deny access to everyone but sysadmin; this would leave existing permissions untouched for when you need to reverse the change.

Hi Jeff,
Thanks for the reply. I'm trying to automate this[^] using DTS packages. As you will see, after running the first sp it is necessary to stop the database, and then start it again. I believe that if I stop the database without stopping the SQL agent DTS will still be running so that it can call the next package to start the database again. This is what I've been told, but as I'm pretty new to DTS I could be totally wrong .
Thanks again.

So you're not trying to stop SQL Server, just the database, right? Is that the same thing as bringing it offline? I found this in Books Online:
ALTER DATABASE database
{ ADD FILE < filespec > [ ,...n ] [ TO FILEGROUP filegroup_name ]
| ADD LOG FILE < filespec > [ ,...n ]
| REMOVE FILE logical_file_name
| ADD FILEGROUP filegroup_name
| REMOVE FILEGROUP filegroup_name
| MODIFY FILE < filespec >
| MODIFY NAME = new_dbname
| MODIFY FILEGROUP filegroup_name {filegroup_property | NAME = new_filegroup_name }
| SET < optionspec > [ ,...n ] [ WITH < termination > ]
| COLLATE < collation_name >
}
<nobr>< filespec > ::= ( NAME = logical_file_name
[ , NEWNAME = new_logical_name ]
[ , FILENAME = 'os_file_name' ]
[ , SIZE = size ]
[ , MAXSIZE = { max_size | UNLIMITED } ]
[ , FILEGROWTH = growth_increment ] )
<nobr>< optionspec > ::= < state_option >
| < cursor_option >
| < auto_option >
| < sql_option >
| < recovery_option >
< state_option > ::=
{ SINGLE_USER | RESTRICTED_USER | MULTI_USER }
| { OFFLINE | ONLINE }
| { READ_ONLY | READ_WRITE }
< termination > ::=
ROLLBACK AFTER integer [ SECONDS ]
| ROLLBACK IMMEDIATE
| NO_WAIT
< cursor_option > ::=
CURSOR_CLOSE_ON_COMMIT { ON | OFF }
| CURSOR_DEFAULT { LOCAL | GLOBAL }
< auto_option > ::=
AUTO_CLOSE { ON | OFF }
| AUTO_CREATE_STATISTICS { ON | OFF }
| AUTO_SHRINK { ON | OFF }
| AUTO_UPDATE_STATISTICS { ON | OFF }
< sql_option > ::=
ANSI_NULL_DEFAULT { ON | OFF }
| ANSI_NULLS { ON | OFF }
| ANSI_PADDING { ON | OFF }
| ANSI_WARNINGS { ON | OFF }

Have you tried the 'Execute Process Task' in DTS ? You might be able to use it to execute net stop MSSQLSERVER and later net start MSSQLSERVER to start it up again.

I am having one column whose datatype is datetime .
so how to set null values in that column ?
when I am passing null values its throwing some error as it is getting initialised to'01/01001'
can anyone help me out?
thanks

You don't say what your data access library is.
If you're using classic ADO editing a Recordset, just set the value to Null. This also applies to calling a stored procedure or substituting parameters in command text: set the appropriate Parameter to Null. From C++, you would use a variant with the vt member set to VT_NULL.
If you're editing a DataTable with ADO.NET, you can use the DataRow object's SetNull method, or you can assign the appropriate column DBNull.Value.

I am trying to connect my vb.net program to MS Access but nothing seems to be going ok.
Whenever I declare my connection object, I get this kind of an error
An unhandled exception of type 'System.Security.SecurityException' occurred in system.windows.forms.dll
here is the code :
This is at the very top
-------------------------
Imports System
Imports System.Data
Imports System.Data.OleDb
--------------------------
Dim cnn As OleDbConnection = New OleDbConnection()
Dim strConnectionString As String
Dim strApp_Path As String
strApp_Path = System.IO.Directory.GetCurrentDirectory()
strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strApp_Path & "\PIB Hiring System.mdb"
cnn.ConnectionString = strConnectionString
cnn.Open()
my database is currently lying in the bin folder.
The problem is it does not seem to like it when I declare my connection. Do I have to add anything to my project.
Someone please help me!!!

Edza,
not sure, as I'd do it differently in C# ( using:
OleDbConnection = new OleDBConnection(StrConnectionString)
isntead, but have you tried leaving out the "..\", so you get:
strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source='..\PIB Hiring System.mdb'"
Alternatively, drop the "\", and put the MDB in the RELEASE or DEBUG folder (depending obviously on which you are using).
strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source='PIB Hiring System.mdb'"
regards,
Pauwl

I don't think it is related to the database. You're getting a SecurityException.
You're probably trying to run this code from the network. Currently, the database access code requires Full Trust before it will run, which will only occur if running from the local machine.
Copy your project to a local hard disk and try again.

What you are saying is 100 percent correct, because whenever I open my VB.NET framewok it gives me this kind of an error:
"The project location is not fully trusted by the VB.NET runtime. This is either it is a network share or mapped to a network share not on the local machine. If the output path is under the project location your code will not execute as fully trusted and you may receive unexpected security exceptions. Click Ok to ignore and continue. Click cancel to choose a different project location."
It runs like a dream from my local disk, just as you said.
Thank you Mike, I never thought this error was the cause of all my nightmares. Thank you again mike, you saved 90% of my time.
