2008 Is there a way to keep a progress bar moving in a VB .Net windows application during long database calls (SQL Server - 10 seconds or so)? I tried a status strip progress bar running in matrix mode and a System.ComponentModel.BackgroundWorker running a progress bar but when the SQL call to a stored procedure is made they both freeze.

OK, so the code in this link: [URL]
allowed me to get a progress bar. It sums up the size of all the files in the folder and then moves them and as it writes them, it determines how much has been written of the total, and sends that to a progress bar.
Now, what I'm wanting to determine is the best way to do subfolders (an subfolders of subfolders, etc).
Would it be stupid/smart to get a list of the folder structure in a particular folder, then recreate that structure, then get a list of all the files and then use the code in the above thread to recreate those files in their respective folders?
I am making a rather simple backup utility that takes one folder and moves it to another and I'm just trying to figure out the most logical or "accepted" way of handling folders when at the same time, you need to have a total of all the size of all the files being moved so you can display an accurate progress bar.
I'm looking to be able to open a .txt file (with sites 1 per line) and visit all of those sites silently while moving a progress bar.

View 1 RepliesI have a filesystemwatcher which place files in a queue when they are created. From the queue the files are further processed (xml into SQL database).
The mechanism works fine, but I want to add a progress bar to follow the progress of the files in the queue: processing 1 of 10......2 of 10......3 of 10 etc.For testing, I created a batch file to simulate the creation of files, so the filesystemwatcher can to his work and place the files in the queue. When I tell the batchfile to simulate the creation of 20 files, I see that the amount of files in the queue change. For example;

In the app I'm currently making, I have two progress bars. One for current task being committed and the other is for overall progress.During runtime, I calculate how many tasks are being run and set that as the maximum. As each task completes, the progress bar is incremented by one.
I want the current task progress bar to show the progress of the current task. Some tasks can take a few minutes to complete so that progress bar works great. But, if the task is super quick, like editing registry keys, I see no progress at all.When I edit the registry, it basically goes like this:
'Edit Key
'x
'x
'x
ProgressBar1.PerformStep()[code].....
It completes so quickly that I never see the bar even move.I also have each task report its name into a label and it skips ahead so quickly that I only see the first task name and the last.Is there any way to make this do a better job at reporting the progress?
I came across a problem in my program it takes too long to calculate the values needed (about 10 sec) .But thats not the problem you don't know when the program is working or not, as it just locks up until its finshed and I view that as a problem.
I need to be able to show the progress of this .I looked at using background Workers but I get exception "Object reference not set to an instance" I believe this is because the background worker cannot write values or something ,As it works will a normal handler.

I am finally making the move to vb.net after having supported VB6 apps all this time. I have been learning vb.net 2010 but am finding it difficult to find relevant information on the COM aspect. In VB6 COM was the dominating feature of the language, however, I can't seem to find relevant information on what has happened to COM in vb.net, does it still exist in vb.net, does it work in the same way or are apps designed in a different way in .net to do away with COM dll's?
View 3 RepliesI need to determine which tab the user is coming from, and going to, when they switch tabs, and possibly cancel the switch. I have tried the Deselecting, Deselected, Selecting, Selected events, and all of them show the e.TabPageIndex to be the same as the sender.SelectedIndex.
Is there an event, or property, that I can use so that I can determine both sides of this, or do I have to hack something together with caching it from one event and using that value in the new event.
I am trying to avoid handling the Deselecting/Deselected events and caching the value to use in the Selecting event. I already know I can do this, so I am asking if there is a cleaner way, without doing this.
I have tried in both C# and VB, with the same results (no surprise).
Am making a game for a college project, its just a mario like game except its a frog.
I want the frog to be able to jump on top of a moving platform in order to get to the other side. However the timer doesn't stop and the frog keeps on moving down. The moving platform has a separate timer called timer2 and the gravity timer is called timer1.
Here is a picture just to show you the game and the frog falling through the platform.
For some reason the moving platform leaves a trail of itself, be cool if you could also fix that for me hehe.
Here is the code for the 'collision '
If Player.Right >= platform.Left And Player.Bottom = platform.Top And Player.Left <= platform.Right Then
Timer1.Stop()
End If

I'm replacing a text box with a combo box. I'm doing this since there are a set amount of inputs for this value. I added the combo box and entered in the values.The problem is that I can't seem to get the value that was selected..I tried setting a text box to the contents of the combo box and nothing happened.TextBox1.Text = cbbct.Text..That is what I tried and it didn't work. This really confuses me since I use a combo box to open save files and that works nicely.Also I'd like to use multiple tabs for my program. I made two tabs then cut and paste my text boxes,buttons, etc. onto them. After I did that I could not open a save file and have it populate the text boxes and set the check boxes. Is there anything I should be careful of when moving stuff to a tab or cutting and pasting?

View 2 RepliesIt is my understanding and experience that VB.NET does not perform well with moving graphics from point A to point B in a form. How do I draw a rectangle or a line and move it from point A to point B? Is there a reliable way to do this without seeing a black rectangle around the moving object on every frame? I've tried this with bitmaps before but it doesn't work. I see the frame rendering and it's way to slow. Perhaps there is an animation Control or library?
