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 would be grateful if someone can help me with this task. I am trying to extract a zip file and update a progress bar as it is being extracted to the d: drive. I assume the progress bar has to be set to the size of the text.zip file and update the progress bar incrementally but not sure how to actually implement it. I have it in a "do Loop" but it does not seem to be correct. If anyone feel like helping I would be grateful for that.

I have a windows form with a progress bar and a button to start/stop the process. I am performing some action when clicked on 'Start' and updating the ProgressBar accordingly and its working fine. But when I try to click on the 'Stop' button when the process is going on, I couldn't access the Window. If I click for multiple times, I am getting (Not Responding) on the titlebar.
Then, I created a thread and run the function (which performs my task and update the ProgressBar) in it. I am getting an error that it could not access the control which is created in another thread.
in vb 2008 or higher :how do i make the progressbar look like the progressbar in xp when i use win7?
View 3 RepliesI have a webpage with a form that is used to edit some object. This object contains a Collection of other objects defined like this: Public Overridable Property Employees As List(Of Employee)
On a form I can delete an employee, add a new one or modify existing one. When I click save new values are sent to the server. On a server I check if the user exists. If exists then I modify its values, if it does not exist then I add it. All employees that exist on the server and were not sent are marked as deleted (State changed to EntityState.Deleted). I try to use the following code (dbCollection = database entities, newCollection = collection sent from the form):
[Code]...
This code does not work, because changing to EntityState.Deleted removes the object from collection, and for each loop breaks, since the collection is modified...I know that I can overcome this problem by using a for loop or adding objects to delete to some other list first, but I hope maybe there is a pattern that would make my code nicer.
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'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.

View 4 RepliesI 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.)

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
