progressbar in a project

[lee123]

i have been trying to add a progressbar to my project but don't know how and the last post i have posted one person answered it but never came back to help me with how?

so i am asking again because this is something alot of people probably would want to know how to do it
so i am placing a code down and hopefullly some one could post the steps on how this could and can be done. not just with my project but others too. so please have a heart and show us who don't know how, but want to learn to do it

here is the code i am wanting to have a progressbar in it to show things happening

Private Sub cmdCopy_Click()
    Dim fso As New Scripting.FileSystemObject
    Dim fld As Folder
    cmdCopy.Caption = "Copying Folder!"
    Set fld = fso.GetFolder(txtSourceOfFolder)
    fld.Copy (txtDestinationOfFile)
    Label1.Caption = "Copying Folder Is Completed!"
    Beep
    txtSourceOfFolder.Text = ""
    txtDestinationOfFile.Text = ""
    cmdExit.Enabled = True
End Sub

as you can see from this code i have the button caption change when i click on it to say "Copying Folder!" and a label to say when it's done. this is great and all but a progressbar would look so much nicer and professional.

The Visual Basic developer environment should offer a progress bar control for you to use. You can get it from the toolbox panel; the same place you got the command button from.

[lee123]

what? that's not what I'm Talking about. i know where the progressbar is located read the question again...

[lee123]

i want to know how to put it in my code to show something is going on, not that i don't know where it is.

Since your first post wasn't properly typed, I misunderstood.
It may not have been what you meant, but it's pretty much what you typed.

I haven't attempted this before, so I don't know if it will work. If it doesn't, you can use the overall structure to work out your own method.

Create the folder first, so that you have an FSO for it. Enumerate the initial folder's file collection for the total number of files, using the Files property of the FSO. Apply that value to the progress bar's Maximum property. Then, do the copy operation. In a loop, enumerate the files in the same way with the new folder, to work out the current number of files that exist within the new folder, and increment the progress bar's Value property until the maximum value has been reached. Finally, display the "completed" message.

yea i guess your right after reading it again it kinda says that, well i guess I'm Sorry About that.tristanlbaily well i have a question lets say someone bring over some music you want to copy from a external hard drive the files may vary and then i wouldn't know what to set the max value to. thats why i made this program to copy my friends folder of music or songs

lee123

[lee123]

o yea i forgot to tell you i don't know ho to do loops, well it's not that i haven't seen one i just never used them before. when i look at one i get confused on how to express it. sounds good when you say it in your head but when you typ it out it never works. that's why i placed the code in the first post so someone could help me place it in the code to understand how it's done. and i just noticed i misspelled your name sorry about that too.

ok i have this, but this isn't working right some of the file are small but this is taking too long to finish.

Private Sub cmdCopy_Click()
PBTask.Max = 100
PBTask.Min = 0
Dim i
Dim fso As New Scripting.FileSystemObject
Dim fld As Folder
For i = 1 To 100
        cmdCopy.Caption = "Copying Files!"
        Set fld = fso.GetFolder(txtSourceOfFolder)
        fld.Copy (txtDestinationOfFile)
        PBTask.Value = (100 * (i / 100))
      Next i
        cmdExit.Enabled = True
        txtSourceOfFolder.Text = ""
        txtDestinationOfFile.Text = ""
End Sub

I did a search on progressbar and i found this code. added my stuff in it and this is what i have so why is it taking too long? I don't Understand how this is done.....I need help!!!!!!!

lee123

[tristanlbailey]

Dont' use the code you've found; it's BAD.
The copy method is repeated 99 times, so it will of course be slow.

I presume you are using Visual Basic .NET, 2005, or 2008?

I am currently constructing code for the aforementioned; if you are using something older (i.e. Visual Basic 6 or VBA), please reply promptly.

[tristanlbailey]

I've just found something that you may be interested in:

http://vbnet.mvps.org/index.html?code/callback/filebackupcallback.htm

I tried making a simpler version, but it was taking too long. The sample above should be your "cup of tea".

[lee123]

actually I'm using visual basic 6.0 enterprise edition.

Tell me one thing. What you realy want is:

1 - Show to the user of your app exactly how much was done, or

2 - Show to the user of your app that your program is doing something?

In the first case you will need to find the file size and use this value as the input for the value of progress bar. In my option to much work for nothing.

In the second case, you can change the Style property of the status bar from Blocks (default value) to Marquee. Doing this the status bar will keep moving always. You can use the property Visible = true to show the status bar just before the file.copy instruction and Visible = False just after the copy is finished.

I hope this help.

[lee123]

Rpicilli, does both of these use the timer control because when i did it without the timer it takes too long, and actually i want to see what is going on so the second one

lee123

[tristanlbailey]

Did you look at the link I provided?

The code in the article should work in VB6.

[lee123]

yes i did and i actually made the program to see it worked and it worked but alot of coding.

Dear lee123
I have already given clue to same problem in some forum (which I don't remember at present).
First of all about your program taking too long to complete:
You have unneccessarily used For..Next loop, in this loop u have used copying of folder which is being copied 100 times again & again and Progress bar is increasing 1 to 100 simply showing that how many times folders is copied.
Now I just give u an idea (of course I will try a program and will post it here):
First, u read the number of files in the folder to be copied (say it is SFolder) and create a Destination folder (may be DFolder). Set max value of PBar to number of files in SFolder. Now copy all the files (using a loop) one by one from SFolder to DFolder and increase the value of PBar to number of files copied.
Second, read total number of bytes in SFolder, set max value of PBar to it. Copy files one by one and increase value of PBar as number of bytes copied increases.
Hope it will give an idea and help u.

[lee123]

hello..smartchap i have waited for you to answer some questions in our last post under "Progressbar" after waiting for a while i moved to this post to see if someone else could help. at the end of your post in the last posting you said:
("If you have any other query please post the code to understand the problem exactly and give solution.") well i waited and no one..anyway let me see if i understand what your saying: and try to figure it out..but the looping is what i don't understand yet becaue i haven't really used it in any of my projects i have made the looping you see is from someone elses code i tried..I'm afraid to say i don't understand how it works..i have to work on this looping until i understand it completely..thanks for answering and coming back to my problem.

Actually I was a little bit busy these days and couldn't open Internet so can't check the subscribed posts. Please try my suggestions and if need further help ask me. As I said I will try same and will post the code, but after some days as I am really busy these days.

Hi

This is a functional application that copy files and/or directory. Try to understant the CODE.

There in no easy way to create programs. If you do not have time to read a lot, you'll not be a good programmer. Excuse me to tell you that but I'm a 52 years old programmer and I learn something new every day.

Besides the code you can see the form image at www.maxidoc.com.br/help.png

In this image you'll see all the names used in the components and the design of the screen.

The components that has no name, let them as the default names.

Create a new project. Open the code of the form1. Copy all the following code into the Form1 code pane. Put the components and rename following the image that you can see in the address above.

I hope you can do it. May be you have problem but if you realy are a programmer, don't give up.

lee123, you can use Timer to make your life easier (you may already know this), with a pseudo-progressbar

1)Drag a Timer control to your form. Set the interval e.g. to 500 and enable = false

2) Modify your code

[PHP]Private Sub cmdCopy_Click()
Dim fso As New Scripting.FileSystemObject
Dim fld As Folder
cmdCopy.Caption = "Copying Folder!"
Set fld = fso.GetFolder(txtSourceOfFolder)
fld.Copy (txtDestinationOfFile)
Timer1.enabled = True
End Sub[/PHP]


[PHP]Private Sub Timer1_Timer()
ProgressBar1.Value = ProgressBar1.Value + Timer1.Interval / 10
If (ProgressBar1.Value = 100) Then
Label1.Caption = "Copying Folder Is Completed!"
Beep
txtSourceOfFolder.Text = ""
txtDestinationOfFile.Text = ""
cmdExit.Enabled = True
Timer1.Enabled = False
End If
End Sub[/PHP]

[lee123]

well thank you rpicilli for that i will give it a try and your right about reading if you have the time. but going to school at night and working through the day is hard work but thank you for your help through this.

and xinariscy, your code looks intersting and simple so i am going to give this a try as well.

lee123

[smartchap]

Dear Xinariscy
In your program there is no use of Progress Bar as it Increments only after the folder has been copied, i.e. value of progress bar is not dependent on size of folder. Yes it is dependent on Timer interval which makes it slow or fast. So I think it will not solve the problem lee123 has.

[lee123]

hey smartchap your right when i tried this way the folder copied and then at the end the progressbar worked strange.

lee123

[xinariscy]

smartchap you are right! That's why I say it's only a pseudo-progress bar. It's only for the eyes. This is absolutely no professional!...

[smartchap]

I have tried code provided by tristanlbailey and its working fine (after some modifications). After I write a simple program will post it.

[smartchap]

First of all sorry for the delay. Please see my submission at following URL:

http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=71156&lngWId=1

It has full featured copying of folder to another folder with almost no bugs. If u find any bug please let me know remove it.

Dear lee123 I have also answered for ur animation post (for progress bar). In a similar way u can solve that problem also.

[smartchap]

Dear lee
I think u must have downloaded CopyFolder_PBar from planet source code (PSC). If it helped u please reply and vote the submission by scrolling the screen of the code )below Download Code) in PSC.

[lee123]

no i got the code from a book i have and it was different than what i have posted (made a little adjustments on it) i thought it would work but didn't.

lee123

[smartchap]

Dear lee
U can download my code and it works fine. However, which code u have from book and is not working, please upload here with the problem u are facing so that I will try to resolve the problem.

[lee123]

hello, i have posted my project on the web so you can see what it looks like, it is different from yours and i have tried yours and it works great but there are things on mine that i don't know where to put your code if you want to see it go to this address or click

here:

the code i tried to use is on the "progressbar post"

For P = 1 to 100 
       Progressbar1.value = P 
              For x = 1 to 100                
       Next x 
Next P

how can i put this kinda code for the progressbar with the timer with my code on the web page

lee123

lee123

[lee123]

Oh Yea I will remove this from the web page in a few days because i have palns for this web page. i am building

lee123

[lee123]

hey smart chap i have deleted the picture i wanted to show you on the web page if you want to see it againg post so

lee123

[smartchap]

Dear lee
Today I was checking my subscriptions and found ur post. Please tell me in detail what u want to be done on clicking each command button (Reset, Start Copying, Move Folder,etc.) and associated Text boxes. Because by selecting folder form directory list box you can put its full path in a textbox and by selecting another dir list box can select destination folder then by clicking COPY command button can copy it. Similarly can move a folder. So please tell details of controls being used by you so that help could be provided. However from my code u can make ur programme. Thanks.

Lee do you want a code which will ask you to copy files from any external device either its a Harddrive, CD/DVD or a PenDrive and copy all music files or whatever to your harddrive???

Regards
ARUZ

[lee123]

now that would be great if you can show me how that's done.

lee123

[EYE4U]

I was a fool i didnt see the date of thread and just answered it :P
Sorry admins

[lee123]

does this mean your not going to show me how now because of the date of the thread? because i still want to know.


lee123

[EYE4U]

NONO
I ll upload the example...

[EYE4U]

This example will automatically detect the drive/device attached or inserted in your computer and will count the number of files in it.

Regards
ARUZ

[lee123]

@EYE4U

In your last post it doesn't show me that, it just shows how many files in a drive, but i like that? how do you copy the music & how can i use a progressbar in it. because really that's what i want to learn how to do it (the progressbar), but don't know how or understand how to and when to?

lee123

[EYE4U]

Sorry i posted the wrong attachment....
