Fire The Timer Or Other Routine While Still The WHILE TRUE Routine Checks For Incoming Connections And Messages?

Jan 24, 2012

I am using sockets to send message between computers. I send the messages alright. What I want is when the message "x0x" comes, the client must be closed within 5 minutes. Teh admin can cancel the request by sending message "-xx" as well. The routine that checks for incoming connections and accepts messages uses WHILE TRUE...END WHILE since it must always listen. Once I get a message, I need to fire a timer control or other that fires within 5 minutes. But the program cant leave the WHILE TRUE at all. If i exit it early, the timer fires and the program does get exit. How do I fire the timer or other routine while still the WHILE TRUE routine checks for incomin connections and messages?

Reference A Particular Code Routine In .net External To The Current Loop/routine?

Apr 17, 2011

is there any way to reference a particular code routine in VB.net external to the current loop/routine?Example:

If Var01 < 5
[Routine A]
Else
[Routine B]
End If

where Routine A and Routine B are code sequences at the end of the entire program -- such as outside of the current sub or class? The idea would be to reference an otherwise repetitive code.

Asp.net - Share A Variable From Sub Routine To Sub Routine?

Mar 3, 2009

I have a sub routine where I pull in information from a database. I want to use variables from this sub routine in another sub routine. I tried making everything public but it doesn't want to be friendly and share.

Dim strEmail as String
Public Sub readDB()
strEmail = "whatever@doohikcy.com"

[Code]....

The readDB would read the database and set the variables and do whatever it needs to do. Then when they submit the form it would e-mail the form to whatever the email address was.

I was looking for something send keystrokes and I found this helpful routine SendKeys that I can use in a VB Script. I wanted to have "Right Control Key + (Scroll Lock & Scroll Lock)" sent to the machine. Essentially, having the Right Control Key pressed, I need Scroll Lock pressed twice. Here is what I tried:

set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.SendKeys"^({SCROLLLOCK}{SCROLLLOCK})"

Why Is Sub Routine Not Firing

Feb 4, 2011

I have the following code:

Private Sub Exceptionquery()
Dim connection As System.Data.SqlClient.SqlConnection
Dim connectionString As String = "Initial Catalog=mdr;Data Source=xxxxx;uid=xxxxx;password=xxxxx"

[code]....

I get the error Invalid Object name 'Scratchpad3' on this line:

adapter.Fill(ds)

I have tried to debug this and can see that the query is correct, that the values that are being passed to the sql server are correct but it doesnt look like my code is firing off the Exceptionquery Sub. I thought to call a sub all you had to enter was the name of the sub such as this line:

Exceptionquery()

I have also verified that the mapping of the buttonclick event is mapped correctly. I have other subs that I am calling in almost the same way and those work.

I know there are several libraries of code out there that can parse CSV files according to the standard, but, for various reasons, I need one simple routine (not an entire library) that parses a CSV into a DataTable or array. Does such an animal exist or is it extinct? (Preferably C# but i can translate vb.net too)

Dec 12, 2011

I am new to vb.net and am trying to design a routine that will allow the user to search for a record and return the results in a datagrid. Then double click on a row within the datagrid to view a more detailed form. I have been able to build the search form but am having problems with the double click event.I found a sample application on the Microsoft web site which is doing this on a smaller scale. The sample is built on the Northwind sql database and searches the customer table when you double click a row in the datagrid the following Microsoft code runs and opens a detailed form.

Memory Leak In Simple Routine?

Nov 11, 2009

I have a service that i believe has a memory leak in one particular sub routine but I cannot find out why.The routine writes data to an opc server every second. It receives a command via tcp, connects to the database for verification of signals and writes the data. When it completes it writes a message back. I am disposing of everything i can think of but for some reason when I check it in the morning then memory has increased dramatically and the cpu usage goes up to 50%. this only happens to the service when I start the client application that sends the data so i know it has to be in this routine.

Pass An Array Literal To A Sub Routine?

Apr 2, 2009

Isn't there a way in VB to pass an array literal? Say the subroutine ask for an array of integers and you have just one. Can't you do something like

DoSomething({MyNum})
instead of
Dim MyNums as Integer() = {MyNum}
DoSomeThing(MyNums)

I'm thinking I'm just missing some adornment to the array literal inorder pass it.

Pausing An Application Until A Sub Routine Is Reached?

Apr 16, 2010

I have a problem with my application "getting ahead of itself" what the problem stems from is i am manipulating a file and then using the manipulated file further along in the program, the trouble is the program is getting to the second step before the file manipulation is complete so i receive a file not found exception. The program that is doing the manipulation has an OnEnd sub routine and i have been looking at event handlers to try and figure out how i can hold up the application until the On End routine is fired. But i have been trying this to no avail, is there an example i can have that waits for an event to be fired?

Routine Unexpectedly Changing Values?

Feb 24, 2009

I'm writing a program to help me understand 3d points and how computers manipulate them to 2d. Every time I run the conversion routine in my program the value I passed to it get's manipulated even though I use the ByVal key word. Here is the code in process order , tell me if I missed something here ?

[Code]...

There is a status box for me to check one of the values :> This is the flow of what I have put together so far. The problem is once I run the program everytime I press the up key to make a call to the GetPoints method the value in MyPoint is changed to reflect the forumula in the getpoints method. I explicitly used ByVal in my variables on the method call so the values in the variable would not be manipulated. I've changed it many times but I can't seem to get the method to run where it does the conversion without manipulating the values in MyPoint. I've done similar things in visual basic .net 2003 , Now I am using the visual basic .net 2008 express edition. I don't if there is a difference in the two or some unknown bug.
