I have the following code that sorts a number of names in alphabetical order(A to Z) Q,
1-How do I change it and make it from Z to A??
2-How do I cut back on the number of loops by placing -1 or whatever, because when I do that I tend to get a messy order

View 7 RepliesFor a project, I need to extract all the frames of an AVI video. This I have accomplished by with free program. The problem: it took a 30 second clip and spit back 5400 some frames, and the image only changes every 20 frames or so. I really only need about 270 frames, but I didn't want to go through each one manually. So, I wrote a small program using Visual Studio 2008 and VB to open each image in binary and compare it to the one before that. If there is a discrepancy of more than 55000 (to accommodate slight errors in capturing), it leaves the file be. If not, it deletes it.
After much troubleshooting, I got it all to work. I ran it on the directory containing the images, but when it finished, only the first image remained. I checked into it, and found that the FSO loop I have set up to loop through each file was pulling the files in apparently random order. It will give me the image "bg(01).bmp" and then immediately "bg(1362).bmp" and so on. And the order changes every run.
I tried setting up an array to generate a list of all the files and then sort them, so I could pull off the name of the file, then the next one, ect. but it took over 3 hours to finish processing the array, and then It was using a huge chunk of RAM.Is there some way to "force" vb to pull off files in alphabetical order? here is my, code, it belongs with a form. fPath is a global variable, simply pointing to the source directory.

and am trying to get that label to work with every item of the combobox. I do not know what property or code of the combobox makes this work correctly, but so far only the first index of the data file gets recognized by the combobox. If I click the next item in the combobox while running the program, it goes to my error message.
I use Visual Studio 2010 and SQL Server 2008 R2. I have created an Entity Model in a class library which I have referenced in a VB Winforms project. I created a data source in the project based on the entity model in the dll. However, all columns in the data source are listed in alphabetical order instead of the native order from the SQL Server database. I cannot locate the cause of this as much as I try.
This might not seem a huge problem, but it is costing me valuable time in rearranging controls dragged to forms and reindexing their tabstop indexes.
I am writing a program which was pretty easier until I got to a certain part. I need to write a code that will let me input 2 alphabets and they will output in alphabetical order

I was trying to edit to get the reults output to a text file. I needed to do this for a few hundred IP addresses, and found kleinma's code. It works great as is, but since the number of IP addresses to ping is so large, I lose some of the info from the console session. I tried to make changes to write the information into a text file, but it doesn't output the results. I am relatively new to VB.NET, so I was wondering if you could please point out the flaw(s) in the edited code. I was trying to use the My.Computer.FileSystem.WriteAllText(File, lineContent, True) method to do this. This does export the IP address list just fine, but the results of the async ping to not get output.
