I have a Console app that loops through a queue and processes each record in a datatable. Each process is long and time-consuming (connecting to a remote website, downloading files, reading them and adding them to the database). I'm trying to implement threading for speed's sake but am having cross-threading issues. (The job takes 8 hours or so to run and the cross-threading doesn't start happening until a couple hours into the run.)I'm trying to figure out how to make my code thread safe. I don't update or rely on any non-local variables, and I don't need to return anything. I've tried locking which works but defeats the purpose of the multiple threads. What other things should I be looking for?

I have a console application I'm using to run scheduled jobs through windows scheduler. All the communication to/from the application is in email, event logging, database logs. Is there any way I can suppress the console window from coming up?

View 5 RepliesI am currently working on an application, where I am using a console application, that will set up the application prior to the main form is run. This is no problem I've got that all working perfectly, the only problem I have is that the console is showing while the application is running, I was wondering whether anyone knows any way in which I would be able to hide the console before it gets shown to the user.
View 12 RepliesHow do I get the console from closing immediatley upon opening in a Console Application program? I have all of the code written but when I run the program it pops up the console window and then immediatley exits so I am unable to read what is in the window to see if my program is operating correctly. This is the first time I've ever used a console window so I don't know where in the code I would need to put "whatever it is" I might need to put to keep the window open until closed by the user.
View 7 RepliesIt sounds confusing but it's not really. What I need is basically a way to emulate the console style text, without using a console. What I'm really doing is trying to do a matrix effect on my form background, by drawing symbols and moving them, alternating their colors (see this video for what I mean).
Is there a way to do this effectively with a timer and a draw event, with the timer calling the draw event and changing the intervals?
I have a VB6 project that I'm converting to VB 2008. There is a routine in this project to LoadArrays.By passing the proc name and arrayName I want the info loaded into, I can set up a series of calls at application load and have these arrays available throughout the application (Info is used in many areas to populated controls)This routine makes use of Getrows.Example:arraydef = rs1.GetRows.This will load all fields and records into the array.Is there an equivalent in 2008?

Now I'm having some trouble displaying the output using the do while loop, and I'm pretty sure it's a loop problem on my code. However, I cannot seemed to find out what's wrong. I looked at the examples of do while loop in my textbook, but I couldn't find anything useful to my problems of my program.This is the output for the do while loop.
Here's the do while loop code

I am trying to learn by creating a small application to help my son learn math. It works but I know there are better ways of accomplishing what I need.
For example:
'Declare variables
Dim num1 As Double = CDbl(frmMath.txtNum1.Text)
Dim num2 As Double = CDbl(frmMath.txtNum2.Text)
Dim answer1 As Double = CDbl(frmMath.txtAnswer.Text)

I imagine I would need something like a do while loop?
When I use a For loop in a For loop the Contains Statement dosen't work! Even my custom one! I even tested mine and it works 100% And neither that or the String.Contains function work inside of For Loops And, I know both of them use loops to search through a string.
My function(It will atleast search once):
Function RealContains(ByVal load As String, ByVal needle As String) As Boolean
load = load.ToLower

I am trying to use the System.Diagnostics.Process class.I have the following Windows Forms application. It consists of 1 Button and 1 TextBox. The only code is for the button click event as follows.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I'm trying to make an application where when the user clicks a button, it generates a series of 100 random numbers between 1 and 1000, and then saves those numbers in a text file. All I could come up with is generating ONE random number, but I can't figure out how to make it 100. Here is what I have:

Okay so basically I want to see if I can make an windows application or just a console application in VB.NET that will verify an MD5 Checksum. I have no idea how to start this out, but I have the ideas of what I'd like to make it.

I am working on an application that ties into a SQL database on the back end. Currently the main form contains a series of combo boxes (Graph type, data format, location, and customer), two date pickers, and a button to launch the selections in a new form. Everything works just fine except there are a couple of things I can't seem to accomplish.
Example Data:
[CODE]...........
Case Select (with commented out lines for variations attempted):
[CODE]..........
1) I would like to be able to use some sort of case statement to color the bars in my chart based on value. I have tried approaching this in a couple of different ways but neither of the options seem to work. First, I tried this (the If Not is used because depending on what values are passed to the stored procedure in SQL, different columns will be returned):
[CODE]..........
Only one series is created with this method, so I can see how/why a Select Case would set all bars the same color. I have also tried creating a series for each row in the returned dataset but it results in 22 bars of different colors, for each of the rows (484 bars):
[CODE]..........
So is there any way to modify the second set of code there to only select the value from the "Percent TMHB" cell that corresponds with Row(i), rather than ALL values from the "Percent TMHB" column for EACH Row(i)?
2) Since I am drawing/creating these graphs in a new window, is there any way to also create a new timer on the "newFrm" and have the tick refresh the data? I've struggled with this but I feel like it should be easy. Say someone chooses a "TMHB", "Percentage", "Chicago", "All" (Graph type, data format, location, customer) and launches the graph, which opens in a new window, then they want to do "TMHB", "Percentage", "LA", "All" and have both windows up, refreshing automatically throughout the day. Can I somehow store the SelectCommand.Parameters values in the new form/timer so that it will query the database again every 5 minutes?
Example code for the StoredProcedure and creating the new form:
If combo_GraphType.SelectedItem = "TMHB" Then
Dim newFrm As New Form
Dim newChart As New Chart
[CODE]..................
Is there a way to convert a windows form application into a console application in visual basic?
View 2 Repliesdetect whether the current application is a console or a winforms application.The reason that I want to do this is that I am developing a library with a global error handler in it and I need to know what type of application it is in order to be able to subscribe to the appropriate exception event.Obviously I could get the user to pass in a parameter specifying what type of application it is, but I would rather deal with that automatically so its all encapsulated from the user of the class.
View 1 RepliesWe currently have +- 20 different console application developed in VS2008 and running at different scheduled intervals, all controlled by Windows schedular. The problem we have come accross is that it is becoming increasingly difficult to manage and maintain these console apps. In some instances a console app will just fail or never run to start with and this creates a lot of problems. In many cases one console app is dependant on another and if 1st one fails well...you see where this is going.
I am looking for a new solution that will help us to trace, debug and manage these console apps better. We are preferably looking for a gui front end, maybe windows app where we can set the intervals for them to sun and view some error reports if they did not run.We are port all the code for the console apps to which ever new appliocation we develop.
I have a problem. I have OCX that works in Form based application. But when I try to use it in Console based application it gives:
Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

I am maintaining some VB.net code and I am more of a C# programmer. I have taken over maintaining several projects from people who have since left the project. The manager tells me that some of the VB.net programs are console applications. Yet in looking through the source code I am not able to distinguish wether the code is for a console application or for some other VB.net program like a VB.net windows application. Can someone tell me if there is a way to determine if a VB.net program is a console application.

When I call a different sub from the main sub in my console application, I have to type in the word twice for it to go to the sub. But I have noticed that it only does that when I have it to be recognized at the second instance (I think I used that right). What I mean by that is this.
Sub Main()
if console.readline = "Test1"
call _Exit_()
[Code].....
If I type Test1, it will call the _Exit_ no problem. But if I call _New_, I have to type it in twice.
I also tried putting them both into if statements instead of elseif.
I have also change the order of the calls, this is where it get interesting to me. If I were to change the call from "Test1" to _New_ ()(So, instead of calling _Exit_(), it will call _New_()) If I do this, then the _New_() will work no problem
and I don't have to type it in twice, but I do for the _Exit_() now.
