I have tried putting my GetFilesRecursive function into a separate background worker to run first so I can update the GUI however I am struggling on how to return the List of found files back to my application (I get cross-threading exception) and how to update the progress bar to show the progress of the GetFileRecursive function so the user knows it is processing the list of files and has not crashed/frozen.
I 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;

one of the BIG hurdles in my simple project, making a search engine. I don't know how at all. The search engine need only to search in one Directory with its sub directories and txt files for criteria, and display the results, with option open from the results. any basic code or example maybe?
View 5 RepliesI am wanting the most efficient way to copy a file with a progress bar updating the copy percentage.
This is the standard copy code I am using:
System.IO.File.Copy(source,target)
This is very fast and efficient. However, I cannot report the copy percentage.I have tried many functions that read and save a file by opening up the filestream and then looping while reading/writing the data. This enables me to report the progress.[code]...
What is the best/efficient way to copy a file showing the copy progress?
I have a problem with a progress bar, i want to delete a folder with this sub:
Dim di As New System.IO.DirectoryInfo(path)
di.Delete(True)
I would like to see a progress bar. I saw some examples with copy but doesn't work with this sub.
Is there a possibility to activate sub from another sub?[code]if a is 1 then I want my program to run 'sub 2' and if it's not then it should run 'sub 3'.

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.

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'm trying to get a progress bar to work while it copies all files in a folder to another. I've gotten the progress bar to show and display the progress, but during the copying process the app stops displaying anything if I click away and won't display anything until it finishes copying everything. It just freezes with a ghost image in the form while it's copying. How do I prevent the app from freezing during the copying process? I can't even minimize it or move the window around. I hope I made sense. Here's my code.
Dim Files = My.Computer.FileSystem.GetFiles(.SelectedPath, FileIO.SearchOption.SearchTopLevelOnly, "*.*")

Is there any reason to favor one of these approaches over the other when inserting into a generic dictionary with the possibility of a key conflict? I'm building an in-memory version of a static collection so in the case of a conflict it doesn't matter whether the old or new value is used.
