View 1 RepliesI am trying to execute a shell command with vb.net that includes variable from the vb.net code.I have experience with batch, and Unix scripting. I had to modify the contents of the code as it is confidential to me at the moment.Example of my problem:
Dim Variable1 As String = "Location_to_.exe"
Dim Location As String = "UNC_Path_Goes_Here"
Dim Options As String = "/Options go here"
Shell("cmd.exe", /C Variable1, Location, Options) This is something that must be run from CMD.exe and I am trying to do it this way to make it as dynamic as possible.
Lets just say we have this as Command1 Dim Command1 = "whoami.exe >> C:Hello.Txt" The program will read a list of users from a text file and then perform the action on each of them. If the user does not exist, or they are part of a password protected computer, I would like to see that in my printout. I have this but am Unsure how to write the If Then Statement (If that is the ebst route to take)

I've done a little bit of LINQ but I almost exclusively return some elements from a collection based on some criteria. Now I'm trying to do something similar; let's say I have 50 winForm Controls in a collection - I want to set the .Visible property = True based on the controls name.
How would I do that? Below is my failed attempt.
myControls.AsEnumerable.Select( Function (myControl as Control) ( myControl.Visible = (myControl.Name <> "Hidden")) )
It compiles and even executes but does nothing.
I am using ASP.NET
If I want to execute my Insert command from my SqlDataSource in my code behind I would do this.
SqlDataSource1.Insert()
But how would I be able to do this in JavaScript?
<script type='text/javascript' language="javascript">
function valSubmit() {
//Need to call the Insert Command here!
[Code].....
Where in my code behind can I place the Insert() command to make sure only after my valSubmit() function in JavaScript have executed it will then execute the Insert Command?
I have been searching for a good code example that will place a small server program on my server and then allow me to use a client on my pc that will tell the server program to run a batch file on the server.
I thought this would be simple... I am finding it not that easy.
We have a server that users need to execute a command on however we do not want them to have login rights to the server so this will allow them to execute the batch file without having to log in.

I'm working on creating a windows service that will send emails to a customer when they are within a month of having their submission expire. I'm using vb.net in Visual Studios 2008
Because it's a windows service it's very difficult to debug. Trying to narrow down my error I created a "sendDebugEmail" method that sends me an email if it gets to a certain line. The emails never make it past "dr = cmd.ExecuteReader()"
I'm wondering what I am doing wrong. My SQL statement should work fine. I've tested it in my SQL server database.
I've created a dummy_database that I just made in sql server as well. I added an INSERT sql statement for the dummy table i have in there just to see if i could actually access a database. All the table takes in is the line number and time it was sent. When I run my windows service that database updates just fine.[code]...
