I have tried using the background worker component...but I havent found a really basic example of how to run the progress meter on the uiwhile loading the grid in the dowork event.. is this as intricate as it looks? I just have the meter tied to the tick event of a timer

View 4 RepliesI am very new to programming and I am having trouble getting my code to work properly.I am trying to write what I thought was a simple program, but I everything I have tried has not worked properly.I am creating a utility that will take installation and database files from one computer and copy those files to a flash drive so the flash drive will have the new version. The flash drives in question would either have one of two previous versions of the software on it or it will be blank. I decided to do this in two steps. First I check the computer for the new database and the flash drive for the old ones. I do this with the following code. [code] Next, I am deleting files from the flash drive if the old database is there and copying the files from the computer to the flash drive and showing progress on the progressbar. Here is where I am going all wrong. I have tried it a number of different ways, and unfortunatly (I'm kicking myself right now), I have not saved the code from the other methods I have tried.I have not been able to figure out how to get the background worker to work with what I am trying to do, though I have seen a lot of code over the past few weeks with examples of how to use it. It is a little above my head in terms of figuring it out by myself. So what I have used is the following code: [code]

I have a menu which when clicked will load form which take quite sometimes (although not very long) but the user keeps on clicking the menu and so the "not responding" message appears on the title bar of the app. I am thinking of displaying "Loading....Please Wait" so that users will stop clicking the menu or will wait until the loading of the form is completed. I tried these code but the form is still displayed even if form has loaded completely. [Code] I like to use the same concept also when the user clicked the save button, to tell the user to wait while changes are being saved.

I am having a problem using ACE. I am on Windows 7 64 bit and I am using Visual Studio 2010. I have inherited a program that needs to be converted from using JET to ACE as more and more users could not use it on their new computers. All this little application does is sort data according to selected fields and then insert blank lines whenever the data changes. It worked fine with Jet built in VS 2005.
Line 32 is where I am getting trouble. I get one of two error when I get to this point "IErrorInfo.GetDescription failed with E_FAIL(0x80004005) when targeting any CPU. I found suggestions from people on the web to target X86 in the advanced compile options but then I get 'Microsoft.ACE.OLEDB.12.0' provider is not registered. This I think is due to the system looking for the 32 bit version of ACE but I am using the 64 bit.
When reading through the code the line da.Fill(dt) is underlined with the comment "Variable 'da' is used before it has been assigned a value. A null reference exception could result at runtime." This confuses me as I declare it at the top and it gets used in the if the statement. The only reason for the underline I can see is that there is no option in case the incoming data is not from csv,xls or xlsx but since the open file dialog doesn't allow for anything else that shouldn't matter.
