Display Progress Similar To Debug.writeline On Windows Form?
Sep 28, 2011
I have a procedure that loops through the directories/subdirectories on a file server and sets the permissions. Procedure is called on a button click of a form.
I need to display on the form which directory is being processed. Similar to if we use the Debug.writeline which writes to the output in Visual Studio. I tried using a ListBox but it only displays the last one and only displays the last one once processing is done. I want to be able to display each directory name as it is being processed.
Psuedo code as follows:
For each dir in L drive
setPermissions(dir)
'display in ListBox dir name
lstProgress.Items.Add(dir.Name)
Next
Simple question that does not seem to be covered: If I use a lot of Debug.WriteLine statements in my code, will they be completely absent in my production version?
I mean: Is the compiler smart enough to not emit any code for those calls? Or would I have to surround them by #if DEBUG..#end if directives?
Console.WriteLine("Network adapter: {0}", adapters[i].Name); Console.WriteLine("Status: {0}", adapters[i].OperationalStatus.ToString()); Console.WriteLine("Interface: {0}", adapters[i].NetworkInterfaceType.ToString()); [Code] ..... What I want is to have this Console.WriteLine displayed in a text box on the form but how to do it.
In the past, perhaps versions of Visual Studio prior to the 2008 that I am using now, I would do something like this in my VB.NET code:System.Diagnostics.Debug.WriteLine("Message")
and the output would go to the output window.Now it doesn't. Something must first apparently be enabled.
If this involves "attaching a debugger", please explain how to do it. It seems to me that it should just work without too much of a fuss.Here's a video explaining the issue in real time and showing you all my settings[URL]..
If I have Debug.WriteLine method in my code, do I need to comment all these methods before producing the Release version? Or does the compiler just ignore them?
I'm an absolute newb to vb (less than a week) and I'm trying to convert a console app to a windows form.In the console app, I have this code
Public Sub rconPacketReceive(ByVal fromserver As Boolean, ByVal isresponse As Boolean, ByVal seq As Integer, ByVal words() As String) Handles rconObj.packetIncoming Dim w As String = Nothing For Each word In words
[code]....
What I want is to have this Console.WriteLine displayed in a text box on the form but don't have any idea on how to do it.
I have a fellow employee who is learning Visual Basic and in one of her assignments she is using the debug.writeline statement. Example: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Debug.WriteLine("This line always prints") End Sub When you run the program, nothing prints to the Output window. I have tried it in VS2008 and VS2010. Brian Allison
I have a vb.net application that uses threads to asynchronously process some tasks in a "Scheduled Task" (console application).We are limiting this app to run 10 threads at once, like so:
(pseudo-code)
- create a generic list of 10 threads
- spawn off the threadproc for each one
- do a thread.join statement for each thread to wait for the longest running one to complete.
What i am finding is that if the code called by the threadproc contains any "Debug.Writeline" or "Trace.Traceinformation" statements, the thread hangs. I can see the thread in the Debug - Windows - Threads window, and switch to it, but it highlights the debug.writeline statement and never gets past it. is there something special about the Debug or Trace statements that make them non-thread-safe? Any idea why this would hang things up? If I leave the debug statement in, the thread never completes. If I take the debug statement out, the thread completes in less than 5 seconds.
Dim hex = "41" Dim text As New System.Text.StringBuilder For i As Integer = 0 To hex.Length - 2 Step 2 text.Append(Chr(Convert.ToByte(hex.Substring(i, 2), 16)))
[code].....
but yet this fails.. (the output isn't itself in a new line) what's the explanation for that?From what I know, doesn't System.Diagnostics.Debug.Writeline does something which looks like this:
I am trying to write some messages to a text file using debug.writeline("Message"). Here is the code.
Dim Tr As TextWriterTraceListener Tr = New TextWriterTraceListener(System.IO.File.CreateText("Output1.txt")) 'Tr = New TextWriterTraceListener(System.Console.Out) Debug.Listeners.Add(Tr) Debug.WriteLine("Test Message")
I see the output1.txt file being created but nothing being written in the file.
im making a web browser which is intertwind in a project, but i cant get the progress bar to display the current percent of a page that is loaded, i want to have 10 segments, each standing for 10% of the total page loaded. So say a page is loaded 67%, 6 out of 10 of the segments will be shown.
I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.
Had this matter on Xp machine and visual studio 2010 ultimate after windows update between december and january: even the simplest windows form program crash on start when starting for debug (inside Ide, F5) unless putting breakpoints on each line of the autogenerated (and marked as "debugger step thorugh") code.(see: [URL]) I was wondering if this matter affects only Xp machines, or if someone with Seven or Vista had same matter.
My program creates a array of numbers as entered by a user and then finally adds them up. The form should be able to display the numbers typed in by the user. I know how to put one of these numbers into separate labels and could display each number that way but I wanted to know if there is a simple way to display the string that is created as a list in perhaps a read only text box or similar?
I created a rectangle shape and tried to show it at my form like this Imports Microsoft.VisualBasic.PowerPacks Public Class frmBoard Dim baseDice As RectangleShape Private Sub frmBoard_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load baseDice.CornerRadius = 5 [Code] .....
i am using MS access as my database and VB.net(2008) as my programming.my table has four columns.my table name is myRecordtbl and the columns are ,myid, myname, starttime and endtime.now i know how can i insert into table. but i got hard how to display times then i can choose to insert into my table.the time should be in the form of Hours:Minutes:Seconds AM or PM with up and down arrow.then when i select the time and hit ADD, it should insert into my table.
I'm using VB 2010, accessing a MS Access database. I have constructed a simple Windows Form returning data from the db, one field of which has a reference to an image I'm trying to display together with the data from each individual record.
I have a field with a product number, that matches the jpg file name (ie, the product number 5505 matches an image that I want to display, namely 5505.jpg). I've even created a new field in the db called 'Image', that contains the full name 5505.jpg.
So, I've connected to the db with an OleDbAdapter, and all the data fields are displayed via bound textboxes. I've been able to display a single 'set' image with a PictureBox, but I'm not sure how the make the connection between the returned data (txtSearchImage which is, say, '5505.jpg'), and getting the Windows Form to display this.
Am I on the right track using a PictureBox? I've tried binding this via the PictureBox properties to the relevant data field, but (obviously) it doesn't make the connection to the image file on my hard drive.
Here's my code so far:
Public Class Form1 Private Sub btnSearchKits_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchKits.Click ' The following line passes the value the user enter for state
I'm trying to display the progress in a progress bar, my app reads a csv file before it processes it to a database.and to set the maximum property of the Progress bar i need to detect the number of lines is there a way that im not aware of other than looping the file ?
Just like an array in a group box or a frame as i used in vb6.
If there are 5 customers details then when i load the form it will add (PictureBox, Label and a listbox) for each customer dynamically and display them with their information. Moreover, if i add 6th Customer information in the database then next time i load the form it should display his/her information as well. I did this in VB6 sometimes back but need a start to do in .net
Private Sub LoadCustomerInformation() Dim Qry As String Dim RS As New Recordset
It's simple question. I am confused since I am new to vb.net and windows form. I would like to display combining of one column (lastname+firstname) in the list box control from the query. My code display something.
I need to display 3 columns and a varying amount of rows (typically around 50) in a windows form, kinda like excel. The data will likely be longer than the window, so a scroll bar will have to come into play somewhere.
I've been working of a Visual Basic Windows Form in Visual Studio 2010 as my first little VB project. It's a form which runs a stored procedure on SQL. I have this all working, however, the stored procedure has a PRINT statement execute if a duplicate is found and stops. What I'd like to do is have this PRINT statement display on the Windows form MessageLabel (label) or have a "successful" message displayed if there is no SQL print statement.
I'd like to use a TreeView control to display database data in a windows form with VB2008. All the information what I found is related to a website design, but I'm working on a database program (sql2005), where I'd like the user to see the structure what he/she make up with a TreeView like control. Just something like that when you explore your hard disk. How can I do that?
