I have a background worker which runs, at the start it stops a timer which has it's interval set to 500ms, at the end of the bgworker sub it starts it again. I've debugged and found out that the line that starts the timer up again (tTimer.Enabled=True) runs. However the timer does not resume. I'm don't know, but I'm thinking perhaps because I'm stopping and starting it on another thread it's not resuming properly or the sub it was attached to (via AddHandler) has been reset or something so it's running but not running the code in the sub it was attached to. If I never stop the timer in the code, it continues to run just fine, but I need it to stop at the start.
View 2 RepliesI am developing a Windows Service in VB2008 and am in the testing stage. What I have noticed is that if I Pause it while it is busy doing something and then resume it, the process generates an error. While I am debugging this I wanted to determine exactly what the difference is between Pausing/Resuming and Stopping/Starting a service.I searched, but most results simply told me how to Stop/Start/Pause and Resume a service, a hurdle that I jumped over many years ago. Does any one know of any resources that go into detail what happens when a service is stopped vs when it is paused?From some experimentation, it seems that if I do not place any code in the OnPause and OnContinue events the Pause/Resume commands have no effect.
View 1 RepliesI am working on a Windows Service application in VB.net 2008. The main objective of the application is to monitor starting and stopping of applications listed in a file. I build the service as system level by using
mManagementStartWatcher = New ManagementEventWatcher("Select * From Win32_ProcessStartTrace")
AddHandler mManagementStartWatcher.EventArrived, AddressOf

Since the coming of Windows7 at our office we have sometimes the issue that the print spool is crashing.Users don't have admin rights to restart the service so that leaves them only at restarting their computer as solution.Which costs alot of time... As we cannot find a final solution to this problem I've begin to write a small tool so they can restart it..I've only hard code a local admin account in the source for this operate for them..

I currently have these group of files I want to rename:
C:Users medinaDocuments estenviromentTestfolderfile1-1111.doc
C:Users medinaDocuments estenviromentTestfolderfile2-1111.doc
C:Users medinaDocuments estenviromentTestfolderfile3-1111.doc
C:Users medinaDocuments estenviromentTestfolderfile20-1111.doc
I have a text box on my form where a I would enter a string of text which will replace the '1111' to whatever the string is in the text box field.
So for example, On my app, in the text box field, I would enter 2222, then when I click on button1, it will rename file1-1111.doc to file1-2222.doc, file2-1111.doc to file2-2222.doc, etc.....

I need a small app that randomly shuffles a set of preloaded numbers. The shuffling will be visible on the screen and goes on continuously (looping) until a key is pressed and as soon as that happens it will show the winning number.Am using visual basics 2008 to develop the application but my problem is when i start the app and hit a key it will loop through my numbers on the text file and it will also display the event but if i hit a key to stop it will not stop..I was workin on the app but my problem is how to stop the loop and resume on the with a keypress. below is the app codes.

OK as far as I know there is no control array in Visual Basic 2005 So how do I do this. I want to change the color of an array of pictureboxes some red some green almost like sending an SOS message. So I already have a string of ones and zero's like 11000110001001100011......these are already in an integer array........ARRAY(40) ......but now I need to transfer this data to an array of pictureBoxes by turning them Red or Green to show the message. I just wanted to place the integer array and the PictureBox array in the same.......

View 19 RepliesI have finally been stumped this semester in my Visual basic course. Mainly because I have to write a program that is started from something that I have not created. I have to create a program that will take in info from the user, then spit out the poker hand that they are holding. For instance, the user will type in 1 for ace, 2 for 2, 3 for 3......10 for 10, 11 for Jack, and then in the next column type in C for Clubs, S for Spades.. and so on. Here is the code I have been given:

How can I make a control array? Or the equivalent.
I am used to Visual Basic 6 which presents the option of whether to create a control array when I copy and paste and control.
I know that this was an advanced compiler option in previous versions of Visual Studio, is there a way to disable array bounds checking in Visual Studio 2008? There's no option for it that I can see.
View 1 RepliesI've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):
ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal
[code]....
This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:
Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)
Read all the elements in the list and pass through ReadArrayString.Split the string using:
DataString.Split(New Char() {";"c})
Pass through
ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)
Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:
If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
TypeComboBox.Items.Add(ReadArrayString(2))
End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal
Bird
Fish
After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:
If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox
[code]....
I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.
I've got the following txt file:
[code]...
Now I want that presented in the listbox with the semicolon and it should be aligned per column so that the numbers, the names, the prices and the quantity are exactly aligned per column.If I read the file like this:
[code]...
Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
I have been tasked to create a Visual Basic console script that asks the user 5 times in a row to input a number into an array (sales figures in thousands), Then you display these results as a sort of tally chart.
For example for the data: sales(10,7,12,5,15)
The output would be

I used a combination of If and doWhile loop codes. Is it possible that the loop will stop at 2nd loop if it will perform a 3 loops?I'm creating an app that if the problem is got the match at 2nd out of 3rd loop, the loop will stop.
View 1 RepliesI was wondering if there was any way to stop a for loop untill i have user input, once the input is correct continue the for loop, is that possible at all
View 3 RepliesI was wondering how someone could stop a For loop in the middle of it, according to parameters. I have tried but cannot find a solution that works, I suppose an example of this would be if a loop were increasing a label by 1 from 0 to 100 and the user sets it to end at 57 or any number in between and when the loop reached the number to stop.
