Open Many Files As You Go Or All At Once?
Jan 8, 2011
I have many container files on a hard drive, inside of them are many images. I have to get a particular image by using an ID to do this I have to go trough each of the container files and find the one which has the ID in it then I can retrieve the image.
I think I have 3 options:
load all the images at start up into memory, some images may or may not be used. as I need each image go through all the container files and open the image into memory. create a dictionary of IDs and what file they are in at start up and then get each image as I need it without have to go through all the container files.

I have an application that can read certain types of files, and I have it working so that if you do "open with" from windows, it automatically starts the application and opens the selected file.
Unfortnately, I cannot get it to work for more than one file.
System.Environment.GetCommandLineArgs() contrains the following:
System.Environment.GetCommandLineArgs(0) = name and path to the .exe
System.Environment.GetCommandLineArgs(1) = name and path to the first file selected to be opened
System.Environment.GetCommandLineArgs().Length is 2 when the user tries to open 1 file, which makes sense since the first argument is the .exe itself and the 2nd is the path to the file, but it does not increase to 3 if the user tries to open 2 files... meaning that System.Environment.GetCommandLineArgs(2) is never populated Here is some sample code that shows the problem: It will recognize no files or 1 file being opened, but if you try to open multiple it will only show the first.

im used to C programming.
Private Sub SaveAsToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveAsToolStripMenuItem.Click
timedate.Stop()[code]......
The problem is that if I save a file I get "myfile.GDL" if I overwrite that I get a new file "myfile.GDL.GDL" ect.the other problem being that the filtering in the windows save/open dialog wont show .GDL files unless I select "all files".

I am using Visual Studio 2008 Professional Edition, and I have a large windows forms project I have been working on. My computer froze up and I had to reboot. After reboot I opened my project, all the files loaded although I got a message telling me that the document load was skipped because of the way the project opened the last time. I am able to debug and run the program so the app is ok. but when I double click on a form to open it nothing happens. Even if i right click it and select "View Designer" or "View Code" nothing happens. No errors just nothing. I was able to open other projects with no problem but not this one, and this project is the only one that matters.

I have created a small application to open the Flash File from my VB.Net Windows Application. To open the Flash file - I have used the Shockwave Flash Object. When I run the application directly from the Solution, the flash files are opening perfectly. But, once I created the EXE and tried to open the same file, I could not. But I can still open other files such as XML, PDF, and Word file from the same directory.

In our application, when you go to "Menu > Help...", it opens our help files in Internet Explorer, which is the desirable effect. However, we have the shortcut key "F1" set to open the help files as well. It still opens the help in Internet Explorer... but it also opens them up at the same time in the user's default web browser![code]...

I am opening a large PDF file using the following
Process.Start(Application.StartupPath & "PREVI.pdf")
I have two questions:
1) Is there a way to go directly to a page number?
2) Can I write a code to have the table of contents show up on the left side of the document so users can click on to go to different sections of the document, not sure if this needs to be done while creating the PDF or if we can do it by code.

I'm working on a project, basically writing a small application intended to allow the user to open files from a specific directory, edit them without saving (through a RTE), then export the edited content to a word document using bookmarks.Part of this program I would truly like to add would be a list box displaying the name of files in a specific directory - and for the user to be able to click on each file name in the list box, and for the file contents to display within my RTE.

I am opening a bunch of excel files to read them line by line into sql at the moment - but ran into a small problem. When using something like this[code]...
if I then open the file manually, it will error the code. I put in some error protection, a try...catch block and if it errored, it will keep trying to open the file. If it opens the file, that means I closed it manually and the program will pick up from where it left off.
This isn't very successful, as other errors won't be trapped right, and the program will crash if I don't catch the errors (they cause an infinite error looping).
Is there a way to have the app/file open somehow, so if I open any other excel file, it won't open, or it will open but not error out in the program cause it's now physically open?

I ran into a problem on a program that is ALMOST done!
I have a populated listview of say 100 image directories. of those 100 images, there are groups of 20-30 images. this number isn't always the same, but would be between 20-30 per group. the time stamp would be within 5 minutes on each grouping. how would I go about pulling the most recent only of the 100 or so images? the most recent within about 5 minutes on the time stamp.

I was wondering if it was possible to check if the file "test.txt" is open? and if so then display a message that the file is in use? My biggest problem is that the file can be opened in notepad, word, excel etc. I have some basic coding, which checks if the file is open - what I am trying to do is check if the file is currently open and if its not in use then proceed with the coding, I have the following coding so far.
Dim Process() As Process = System.Diagnostics.Process.GetProcessesByName("notepad")
Dim Process2() As Process = System.Diagnostics.Process.GetProcessesByName("word")
For Each p As Process In Process
