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.
Is there a way to make ProgressBarRenderer.DrawHorizontalChunks actually work the same as the standard ProgressBar rendering?
If you create a Class that Inherits ProgressBar and override the OnPaint event then you have to render the Empty ProgressBar and it's fill% manually. This pretty easy with the ProgressBarRenderer. However, the DrawHorizontalChunks function is ugly compared to how a standard ProgressBar renders itself.
Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs) ProgressBarRenderer.DrawHorizontalBar(e.Graphics, e.ClipRectangle) ProgressBarRenderer.DrawHorizontalChunks(e.Graphics, New Rectangle(0, 0,

I also have a second more minor issue in that I Shadowed the value property (for various reasons), so PerformStep (which then has to be Shadowed to keep the Value property in check) causes it to increase in blocks rather than smoothly growing between the two Values (old value growing to old value + step); the only solution I can see is to extend the code in the Shadows Sub PerformStep code to move the Value property gradually between the old and new values.
i've made a tabbed webbrowser (but i'm new and a noob with VB.NET)The tabs system is working, but the progressbar doesn't work and my titles aren't changing.
I found that when group by multiple values does not work well with VB.NET, but it works well with C# ,here are my code, is there something wrong with my VB.NET Code? Here is my VB.NET code:
I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.
I have a form that works on my local Machine I created into. I have Office 2007 on this machine. I created the Form with the Excel 12 Reference. I move the Entire conetence of the Project folder to my work computer. Which has Office 2003. Do I need to recreate the form with the Excel 11 reference. I could not get the form to work on work computer. IT has a com error. I am acessing the EXE for the debug folder w/in the Bin Folder.
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:
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 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

my update script in VB.NET, i'm making some stuff, and I want, while all funcs are executed, a progressbar to be displayed? How to do that? Here is my execution sub:
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.
how I can place a ProgressBar in a Listview? I know I can get the coördinates of the item and place the ProgressBar, but that doesn't work properly. I saw much codes in C++, but not in VB.NET. Does anyone has a Control or a Code for this?

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
