If I insert in a Form a progressBar (Max value 1000) and I write this very simple example
For x = 0 To 990 Step 10
ProgressBar1.Value = x
Threading.Thread.Sleep(5)
Next
Me.Close
If I run the code with Windows7 setted as Windows Classic I can see the progress bar value go to the max value and after few time the Form Closes (same with Windows XP).But If I run the program with Windows7 setted as Windows7 Basic the progress bar value ONLY goes to the HALF max value and after half time the form Closes.
The code is the SAME, the PC is the same, Seven is the same (only personalized with different theme) but under Windows7 Basic it seems that For x = 0 To 990 Step 10 becomes For x = 0 To 550 Step 10..The INCREDIBLE thing is that if I insert in the For... Next a row like:
Debug.Print(ProgressBar1.Value.ToString)I obtain right values until 990... but for my eyes the progress bar only goes to half value in half time, then the Form closes.
I am trying to insert 11000 records using sqlite in database but values arent inserted though program executes without error.[code]How should i insert?
I'm adding records to my table which works fine. However, when I want to add a lot of records it takes some time and it looks like nothing is happening. I want to add a progressbar to show the progress.
For Each dgvrow As DataGridViewRow In mydgv.Rows progress.Maximum = mydgv.Rows.Count Dim cmd_save As New MySqlCommand("INSERT INTO ....etc", conn)
I am trying to use a progressbar to show on main form and then finish when next form is loaded, I have got this code.
1. When I click on button, it must open next form, but the next form must only open when the data in my list box has been loaded from Access Databse. When I run my program, it only shows the progressbar and don't open the next form.
Main form code:
Public Class Main
Dim PB As ProgressBar
Private Sub main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub
I have a form let's call it Form1 that calls another form(Form2) Form2 to has a bit a code that needs to load in the LOAD_EVENT and takes about 4 seconds.
I have made a new form(frmProgress) that only has a progress bar.I want frmProgress to show up and load the progress bar meanwhile Form2 is loading.I've tried using BackgroundWorker but I can't seem to get the grasp of it.
I have a form where I generate a report on some button click. I need to show another Form in Modal Form, And Place Progress bar on that and Increment the status, from calling form so that when progress bar is running user cannot close the form (where I placed button for showing report). To calculate progressbar's percentage is in the form where button to show report is.
I read several posts but I didn't still find solution on my problem I created 2 forms: first is main where I do operations on excel file with 20000 rows and in second form I created progressbar. the name of main form is form1.vb and the name of second one is wait.vb In main form I wrote:
I pass progressbar byref to the processing() function on ClassLibrary. My main form freezes when i run this.How can i prevent my main form by freezing? My Function is always on the class library, so is there any way or any type of approach to this problem. I need the progressbar to be accurate in showing the process.[code]...
(1) User should be able to see progressbar form in continuous/marquee style. (2) When one task is completed, title on the prog.bar form is changed (3) when final task is completed, progressbar should go away.
What my architect wants: [Code] Downloaddata.vb class, that will actually do the work,and will implement the interface. So DoMyWork(dim frm as ProgressBarForm) implements Iwork.BeginWork.
Twice, it will report the stauts back to progress bar form. ProgressBarForm.vb class(it has BGWorker Thread) will have one public method(name ShowMyProgress) that Downloaddata class can call from its DoMyWork method when status is changed. And also implementation of all 3 events of worker thread.
My Questions:
1. Where should I put BGWorker.RunWorkerAsync 2. What kind of logic should go in ShowProgress method in progressbar and also in DoWork event?
Do I need application.doevents? In nutshell, how Progressbarform and DownloadData will communicate back & forth?
I'm trying to make a progressbar that shows the load time of the next form.I've tried alot of different ways to do it, but it and the speed is always the same whether the next form loads faster or slower.I'm not sure what variables to use or anything.
I recently finish my Microsoft VB.net training and learning something about delegates. I have two delegates in a excel source to control a progressbar and a text box on the mainform
Public Delegate Sub ReportProgres(ByVal percent As Integer) Public Delegate Sub ReportText(ByVal Mytxt As String)
I want to use these delegates in a second excel source also. It gives declared in the first excel file and two conflict errors in namespace windows application.
when i run following code it runs ok and problem is that during running code when i minimize the form and then restore again the form, it not display changing value into label1 and progressbar also the form looks like hang what is its solution?
I have a textbox named txtWith (Amount where cash should be inputted) and I want the input to have comma. Example, if I input 1000, I want it to be like this 1,000. By the way, this is my code in the textbox.
///THIS CODE WILL DISABLE CHARACTER/// Private Sub txtWith_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtWith.KeyPress '////////////////LETTERS DISABLED ONLY/////////////////////// If (Asc(e.KeyChar) >= 48 And Asc(e.KeyChar) <= 57) Or Asc(e.KeyChar) = 8 Then e.Handled = False Else e.Handled = True MsgBox("Please input numbers only!", vbCritical, "Error!") End If End Sub
I am trying to extract whichever number is next to a=. I hardwired a value of 1000 for testing purposes.I keep getting an error saying Index and length must refer to a location within the string.Parameter name: length when I try and use substring.
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim text As String = TextBox1.Text Dim comp(9) As String
I always have this problem. I have a textbox but is disabled and you can only input through a button. So, I want the input number "1000" to be like this, "1,000" but I don't know what code to put. Same thing with 100000 = 100,000
I am trying to write a simple code that will essentially change the background oclor of a form from say red to green, like every five seconds.(Actually, it will be green 4 and red 6 seconds). I set my timer interval to 1000 and enabled it. So when I write my if/then statements in the timer area, would I be using timer.interval <=4, or timer.interval <=4000 to count off four seconds?

I have to create program that adds the whole numbers from 1 to 1000 and displays the sum in the label. Create a variation of this program that allows the user to specify any starting whole number and any ending whole number (10,000 or lower) and then adds all the whole numbers in that range. Allow for the possibility that a user may start with a high number and end with a low number. Format the label so that commas are displayed and there are no decimal places showing. I need help with the codes.
I am trying to make part of a form program do the following When I exit a text field, I want to import some datainto a datagridview control.The columns are (1)Key, (2)Location, (3)Part Number, (4)Serial Number, (5)Description.There are up to 1000 rows of data in anyone of the spreadsheets I am working from.By using a datagridview, I can click the header and sort the data by either of the 5 columns, and when I select a data row, the Key number is reported back (for now, into a text box)I will be using the key number to further manipulate the spreadsheet after I have solved this problem.There are thousands of articles on DataGridView, and over the past 8 days, I think I have read them all. I have tried many downloadable routines, which haven't populated the DataGridView at all.Please can someone show me a simple program which will do the above task, and will give me a base to start from.I am running MS Office Pro plus 64-bit on Windows 7 and Visual studio 2010 pro
I have a listbox with 1091 items in it, which I am adding during design time. Every time Visual Studio tries to save after I manually populate the listbox it will hang indefinitely. Is there any way around this, am I trying to add too many items to a listbox?
