Progressbar Does Not Run During Operation
Oct 14, 2010
I have a form called frmReport and on this form a user makes selections and clicks the "btnBuild" button which in turn creates a crystal report and displays it. However sometimes this process can take some time to build the report. So I placed a panel control along with a progress bar to let the user know that the system is working. However when the form runs the progressbar does not run until the last few seconds before the report is displayed. how to get the progressbar to "run" while the report is building ? (The progress bar is set to marquee.)
Private Sub btnBuild_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBuild.Click
' Display panel control with progress bar

i want to ask about progressbar i mke some looping, maybe long looping, can be 2000 record or maybe 20K record but i want the progressbar show the progress of that looping example = i have 20.000 record, when it loop on the 2.000 record, the progressbar automatically 10%, then if 2.200 then progressbar become 11%.. and the progressbar is dynamically changed within the record i have read some about BackGround worker, but i dont know the concept.so i count the record, and then set the maximum value for progressbar, and inside looping, i set the value 1 by 1 but, if i count it first, then it will 2 time loading and not as fast.
here is my simple code
Function nilaicari(ByVal sDir As String) As Integer
If (countfolder(sDir) = 0) Then
For Each d In Directory.GetFiles(sDir)
z += 1
[code].....
it work fine, but i think it not effective because it process 2 time how can i make it loop, and then immediately make the progress of the looping ?

I'm trying to convert code from Delphi to .Net. I'm stuck on one line:
//Delphi code ss := Copy(ss, Length(ss), 1) + Copy(ss, 1,Length(ss) - 1); 'vb.net code ss = ss.Substring(0, ss.Length - 1) + ss.Substring(1, ss.Length - 1)
Delphi combines the two substrings, while .Net just concatenate them like a copy.

I'm making an application with a custom progress bar (picture box) using the formula
pbxProgress.Width = (intValue / intMax) * pbxBar.Width
where pbxBar.Width is the maximum length.Along with that, I'm using another formula to change the RGB color of pbxProgress while it increases. I'm using:
pbxProgress.BackColor = Color.FromArgb(0, 0, (intColor / 255) * 650)
I came to that last number; 650, by guessing and checking. If I use that number, the RGB increases perfectly with the value of the progress bar so that it ends up being at 255 when the bar is completely full. The only trouble is, I'm not sure how I got that number, and I would like to make a more general formula for future use.

I am using a progressbar control in a splash screen.
In my code I am updating the progress bar value with each step -
In Form_Load of the main (hidden) form:
frmProg.UpdateProgress(10, "Checking Connection String")
CheckConnectionString()
frmProg.UpdateProgress(20, "Checking Crystal Reports OCX Files")
CheckOCXVersions()
[Code]....
Is there some event I can use to find out when the progress bar has finished redrawing?

I'm attempting to use a ProgressBar to show while I'm loading a database. The table I'm loading isn't exceptionally large (about 7900 records), but my program nevertheless takes 39 seconds to load it! I think this is a little too long for a wait cursor, but I'm having problems figuring out how to use the ProgressBar properly.
I would show you what I've got in the way of code, but I trashed it (accidentally) and would like to start over the right way. Please just point me to some tutorials that make sense (if possible) or any code snippets, etc.P.S. I'm loading the database from a button_click event on my main form, which (eventually) raises my 2nd form which has the database displayed in a datagridview control.

I'm doing some converting of wav-files to mp3 and I use lame.exe. Now, when using "lame.exe sourcefile.wav endfile.mp3" in cmd it works great and shows it's own progressbar. But is it possible to have my own progressbar inside my application form to show it's progress? Because when using the command from my application, it just converts and doesn't show anything.

This program is finished already, and i am using it now, but I want to add progressbar so that i can see the progress running to make it more beautiful
i create an apps which is capable of installing apk file on android phones. QuoteQuote: This is base on ADB command "adb install applcationname.apk"
we can install apk on command prompt using adb install command The scenario of my program is like this: all the command on cmd will appear on my form (This is all OKey) the apk's name is on my listbox1, if I select the items on listbox1, the name of this item will be written on my txtCommandInput (my textbox)
this is my sample codes
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
Dim _items As String = ListBox1.Text
[code]....
if you press the button it will throw the command from txtCommandInput.Text and the result will displayed on cmd, so the "adb install command" will run. all of this thing is working fine, except the progressbar Now im reading this book about progressbar and backgroundworker sad to say i really cannot make it work, that while the installation of this apk the progressbar value is exactly 100% after the installtion finished
how the progress on progressbar will be the exact value and result of this apk installation
