Remote Execution Of SQL Stored Procedure
Jan 26, 2012We are working on a VB.Net project to execute a SQL Stored Procedure and passing it parameters. We have the execution up and working as expected, however the application will only successfully execute once. On the second execution, it throws the following error: Login failed for user NT AUTHORITYANONYMOUS LOGON..For readability I have broken the code down into relevant 'chunks'.[code]As mentioned, on first run - this works without issue. However future executions fail with the error noted above. To clear the error we have to open the stored procedure in Ms SQL Management Studio, click to modify it, then chose execute from the tool bar. Obviously this doesn't actually execute the stored procedure or return results, but for some reason seems to clear the error.the stored procedure does collate data across several SQL servers, so I am guessing its the 'hop' between them that's causing the issue.

[Code]...
I would like to do the same thing in .net using WMI, and I tried to do this on my own, but my code is not working properly. If I specify my logon credentials, the process will execute on the remote machine and the code works fine, but I want the program to send the WMI query by using impersonation. I believed this was supposed to send the user credentials of the user using the program to the remote WMI provider on the remote machine. Here is the code I am using:

Debugging Execution Of Database Function Call To Remote Sql Server?
Sep 14, 2011Working in VWD 2010 Express I have an aspx.vb file with the following connection string:
Protected Function getPasswordLength() As Integer
Dim conn As New SqlConnection("Data Source=localhost;database=MyDB;Integrated Security=true")
Dim cmd As SqlCommand = conn.CreateCommand()
[code]....
This works when the code is on the web server / which is collocated with the SQLServer.However, when I want to debug, I have to copy to the server. I would like to be able to "debug in place" on my development machine and only copy files to the production machine periodically. Technically the production machine is not in production at the moment, but that's beside the point.Anyway, I followed the following instruction: [URL] I can now see the remote database, functions, etc. on the other machine (from the VWD running on the development machine). However, I thought I should then be able to execute this same code locally on the development machine using ctrl-F5, but I get the following error:
**Server Error in '/' Application.A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)**

View 8 RepliesConnect To Remote Computer And Display The Status Of Process Running On Remote Computer?
Dec 27, 2009I'm trying to develop a windows application where i can get connected to remote server and look for process state going in remote server.We have many remote servers where automatic installation of software going on. We have an xml file(installstatus.xml) where it tells us at what stage the installation is (Example : Inprogress , Completed, Failed.)
So our aim is to develop a windows application where i can get connected to that servers and look for their installation status(may be we can use installstatus.xml to look for installation status). Every time i connect to a server, the server information should get stored in XML file(i want to create a xml file where all the servers list i connect to should get stored)
The UI at left side should will have list of servers i can connect to. When i get connected to server, at right side of UI, i want to display the status of installation (In progress, failed , completed).
Compilation And Execution
Nov 12, 2011read the COMPLETE email before giving me instructions.I say that because it seams like who ever is responding is only reading part of the email and responding.I have followed your instrutions and I still can not get myhello.vb to compile.
Both vbc.exe and mylello.vb is in the same folder c:program files
"C:Program Filesvbc.exe myhello.vb"
You stated that I should run command prompt as administrator and tye the same command as you do. what (as administrator) is. Please walk me through the complete process. Please do not tell me to run the command prompt as administrator because I do not know what that mean.I can not speak to my administrator. Also I attempting to compile a sample VB that came with the software, so using Visual Studio is not the solution.
Deferred Execution In .NET?
Jan 26, 2011Private Sub LoadData(Of T)(ByVal query As ObjectQuery(Of T),
ByRef result As IEnumerable(Of T))
If Connection.State = ConnectionState.Open Then
result = query.ToArray
Else
AddHandler Connection.StateChange,
[Code]...
In the above code I am trying to recurse the LoadData function when the connection is unavailable, I want to defer the loading to when it becomes available. The problem is the above code leads to a compiler error, since a ByRef param cannot be used in lambda expressions.

Hide Both Of The Modules Upon Execution?
Feb 22, 2012I have finished creating the code for my client/server application although both parts currently execute modules/in console(this was for testing purposes).I am now looking at making both parts of the program completely invisible (they will eventually be executed as a Windows service upon startup). How do i go about this? Does the code need to be copied in to a "Windows Service" project, or is there a way I can hide both of the modules upon execution?

Getting The Dynamic Code Execution?
Aug 23, 2010i'm building a basic server program that I want to recieve commands and execute them sent from a client program and I'm using my home network to test it out. I've got no problem with the communication between the client and server programs and have used a simple Send Text function to communicate to the server program which simply brings up whatever text was sent in a message box.
I've decided that constantly updating the program and transferring the new EXE file just doesnt work as I have to keep starting and stopping the server program to do that just to update the list of commands it recieves. So say for example I've got a button on my client program that tells the server to open the cd-rom draw on that computer, it sends this in the form of simple text openCDdraw" and when the server recieves this, it pops open the cd draw and so on and so on... but I thought a better way of doing this may be to say have the commands listed in a SQL database and when the server recieves a message it searches through the database to find the correct command and executes the code associated with the command.
Now I can retrieve the information fine in to a string variable ("Dim a as string, a = dr.getvalue(3)") but where do I go for there? This is the problem see. My apologies if I've gone a bit long winded on this one but thought it necessary to explain what I'm doing. I've heard of dynamic code execution but when I tried a project I found on the internet it had been coded in C# and I don't know any C nor do I want to as I'm a VB veteran and have updated myself with the way of .NET now so am not going to start all over again with learning C. Does anyone know of an easier way of doing this? Static code is so easy to do because it is typed straight into the coding sections and I had already thought about creating loads of subs/functions to execute each command but again that involves updating the EXE file every time so there must be a better and easier way of doing it.
Can I also just point out that this little project i'm working on is not for a TROJAN or whatever that old NETBUS program used to be called, it is simply so I know how to do it and can use it for other things that I'm working on and through. Also I'd just like to know how to retrieve and execute code from a database or text file.

View 6 RepliesMultithreading - Thread Of Execution In .net/COM Dll?
Jun 23, 2012According to the answers to another question, the VB user interface cannot be updated if the thread that created it is busy: hence why big computational jobs usually have to go in a background task.Here's what's mystifying then. I have the following code. It's called over in-process COM, like this
client calls showform()
client does loads of work, freezing up its own UI in the process
client finishes work, returns to updating its own UI
At step 2, the VB form is there but frozen - you can't interact with it. At step 3, the VB form becomes usable. But why is this? Surely the thread of execution has returned to the client? If the client is somehow handling events for the form, by what magic did it know what events to handle and where to send them?

View 1 RepliesVariable From Execution Path?
Jun 3, 2012I am trying to allow my VB.NET EXE to have a variable defined by the run command. The problem is I have no idea what the terminology would be for this type of run.
For example - the shortcut is set to do "myexe.exe debug" This would set a variable to "debug" which on execution my app knows to enable a debug mode.I've done it in batch scripts before - it just enables the "%1" variable or "%2" based on the location (e.g. test.bat hello world - hello would be %1 and world would be %2).Hopefully I explained it well. I tried searching for "variable in execution path" and "variable on execution" with other mixes, but none of those searches return what I am looking for.
