I am listing the following three subrointines....
Private Sub OutPut(ByVal Offset As Long, ByRef path As String) 'Orig
If Not cbFiles.Checked Then
item1 = New ListViewItem(Offset)
[Code]....
They have the same name but a) different types of aguments or different numbers of arguments. This is legal in VB.
I have a slew of sub routines that I need to use in my software because each website that I will be accessing don't all use the same methods.....go here...click that...go here...click that...etc etc
So I've divided them into sub routines and call them when I need them but the coding is getting so long that it's becoming confusing to keep up with each sub.
Is it possible to place the sub routines into an independent file like a class and then call them from the file when I need them so I can free up some space to code?
VB 2010 express Win XP pro I'm tryimg to detrmine the time taken for various routines, and not having much luck.From what I can gather, it seems that short times and very long times are a problem, as is my understanding of what I have read. cpu speed shown is correct.I checked a few routines, very short routines return 0, to be expected, ?resolution.Longish times (about 33 seconds with a stopwatch), report to be 177 seconds.

I'm trying to have it so that when the user selects an item from the combo box, it will display the right nodes for that selection in the treeview control. For example: User selects Artist from the combo box and the treeview displays the letter of the artist. The user selects a letter and it will display all artist with last names beginning with that letter. Unfortunately when I select a selectedindex, the treeview doesn't display anyting, it's blank. What am I doing wrong? Here's the code I'm using for artists:

I have some common code that I would like to share between pages and I have been messing around with App_Code classes which is great but I would also like to use code that affects drop down lists example:
Sub Set_FirmType(ByVal Sender As Object, ByVal E As EventArgs)
subcategories.Visible = "false"
supplycategories.Visible = "false"

Is their a way to put this in my App_Code class?
Note that I'm aware of other yield in vb.net questions here on SO. I'm playing around with Caliburn lately. Bunch of great stuff there, including co-routines implementation.
Most of the work I'm doing is C# based, but now I'm also creating an architecture guideline for a VB.NET only shop, based on Rob's small MVVM framework.Everything looks very well except using co-routines from VB. Since VB 10 is used, we can try something like Bill McCarthy's suggestion:

It definitely isn't as elegant as C# version, but it looks to be doable. We'll see if there are any problems with this. If anyone has better idea, I'm all ears.
I have LaPack numerical package , I want to compile with Visual Fortran (INTEL) using vs2008.I want to use the routines from a VB.NET program.How can I call the routines from VB ?
View 9 RepliesThis will no doubt sound like a pretty dumb question to some, but, despite having written many useful single-thread apps over the years, I don't understand enough about threading yet.
Consider this scenario:
There are four modules, each on its own thread, that can happily run concurrently most of the time. However, each module occasionally causes a few seconds' intensive disk activity (by design) and it would be more efficient (faster, less fragmentation) if only one module at a time wrote to the same physical drive.
It would be useful to have something like a baton that modules within a given scope can pass around, perhaps dependent on their respective priority levels.
I'm using PInvoke to access some routines from a third party library, however i'm getting SEHExceptions when trying to use callbacks defined for one particular method. The callbacks are used to provide feedback from other unmanaged methods within the third party library, passing a string back to the calling application containing a status message.

I am trying to retrieve all processes running on a machine with the usual information; process id, name and the memory usage. I am trying to export it all under one xml file, however to get all the information I had to use 2 separate methods. To get the process id, name and session id (process owner) I used the following code along with a dictionary and a class, using a .net library called Cassia.
Using server As ITerminalServer = manager.GetRemoteServer("Spartacus")
server.Open()
For Each process As ITerminalServicesProcess In server.GetProcesses()
If Not String.IsNullOrEmpty(process.ProcessId) Then
dictprocess.Add(process.ProcessId, New Processes(process.ProcessId, process.ProcessName, process.SessionId))
[Code] .....
As you can see the unique id (process id) is the same in each xml. Is there any way I can write the xml so that the information from both methods can be under one tag?
i have a need for my vb.net app to perform methods at regular intervals. it needs to check sql tables and react to data found, send email and sms messages. i've tried using a loop but this only allows me to perform 1 check ie checking sql tables. the app needs to execute a method every x minutes. i tried using system threading but i got errors.
View 1 RepliesI have a Windows Forms app, with a TabControl. On the first tab (which is a bunch of textboxes), the CTRL-x/c/v keyboard shortcuts for cut/copy/paste work as expected. On the second tab (which is a DataGridView), the keyboard shortcuts don't do anything. How do I hook up these keypress events to my cut/copy/paste routines? I already have great cut/copy/paste routines for my DataGridView--and they work fine when launched from the tooltip buttons or menus. I just need to hook up those subs to the CTRL-x/c/v keypress events.

View 2 RepliesI'm writing a really simple file updater which downloads files off from a website and saves them. The download routine is working well, except that it freezes the project while attempting to connect to the host. Easily solved with threading except now when I try to access other form items such as text boxes, labels, form caption, it says I am not doing it in a safe manner and prompts an interrupt in debug. I did some reading on it and I'm still not sure what to do, I'm very new to vbnet and it is still a little confusing to me.

The VB format(object,formatString) command fails when placed in the handler routines of a DataGridView.In the following procedure the newCellValue returns the Format string value instead of a formatted cell value.This pproblem occurs in both the dgv_CellFormatting and the dgv_CellClick routines.The same commands work properly when placed in a procedure on the form.

I have googled high and low to find an answer to this but I must be searching wrong.I have an application which has a listview displaying some items that are stored in a SQL Compact database. I am using a second form to add new items to this list directly into the database.When the second form closes I want to call the sub in my first form to refresh the list from the database.
How can I get it to fire the form1 sub routine on the close event of form2
Both seem to accomplish the same thing--exit a subroutine. Is there any difference in how they work under the covers?

I'm writing a class-library in VB.Net and one of the subs that are being called from the application which is using my library has more or less the following syntax:
Public Sub LoadDict(ByVal PhoneticType As String, ByVal strDict As String)
where PhoneticType can be phonSoundex, phonDoubleMetaphone or noPhonetic
I want to give the application-developer a possibility to select the PhoneticType from a list when writing the call of above sub (I think it's called attribute-arguments). This would make it easier for the developer since spelling-errors can be avoided and which will avoid errors when using the library. I think it's all about attributes but I haven't managed to get it to work despite trying.
I've created custom buttons in a .dll and they work fine, so I thought I'd have a go at creating my own sort of listbox to replace the standard one in my applications. It's basically a panel with a few labels and a button (eliminating the need to select an item in standard listbox then click a seperate button). I want to add these panels to a panel on a form, at run-time, based on rows in a db.
If I try adding any arguments in the New() section of the class file it won't let me use the panel in my toolbox. Is there a way to pass arguments to custom controls, I need a new custom panel for each row in a db so need to pass an id to it to specify records; or even load the records in my application and create a new panel for each record, using info passed to it to fill in the labels on it. Or can I create the panel at run-time and refer to labels within the custom controls, setting their .text properties that way?
I am new to visual basic 2008. I can't seem to grasp arguments in a function. Can anyone give me a simple explanation of what they are, how they work, and why we need them?
