I wrote a programme about 12 years ago in visual basic 3.Since then I have moved interstate and changed jobs quite a few time and lost the original Visual Basic 3 discs.Visual Basic 3 saved the files in a binary format that has not been used in any other version of Visual Basic. So now I cannot read or modify the files.
View 3 RepliesI was wondering if I could somehow binary coding, if not all coding of a file.In Visual Basic 2008, I use this method:I click a button on a form, I browse the file, I select itand then I click open and it fills a RichTextBox with 1 and 0's in binary form.. You know, drag a .exe file into notepad and you get random jiberish and inunderstandable characters.Well, this method does just that, BUT! It's waaaay to slow
Dim input As New System.IO.FileStream("File to get binary from.exe", IO.FileMode.Open) 'Create a new File Stream
Dim bytes() As Byte

I am trying to locate the runtime install for Visual Basic 6 Runtime Extended Files. I am not a developer just the guy truing to get it onto the systems for them. My question is simple anI hope the answer is the same. We are converting our systemsfrom Windows XP to Windows 7 and we need the extended runtime modules so a number of our applications will actually work.
I cannot locate the install for this in the Visual Studio download area. Is the re-distributable part of the studio install (so it should be on one of the developers systems) or do I download it from somewhere else.

how to sort the group of files in the directory using Hashtable by values?
i'll have more than 500 no of files in the below format:
prod_orders_XXX_<TimeStamp>.dat
XXX = symbol of the product and the length may varies.
<TimeStamp> = date and time
Multiple files for the same XXX are possible with different time stamps.
Here are some examples:
prod_orders_abc_20122001083000.dat
prod_orders_abc_20122001083111.dat
prod_orders_xyz_20122001093157.dat

I have an issue with creating a VB program. I reference files on my computer that are displayed in a webbrowser in the program. The issue comes when I install the program on another computer because of the file path. The program is looking for the files on the computer I created the program on because of the file path, instead of looking for the files within the program resource files.
For example, I created the program on Computer A and referenced File "C:ComputerAMy DocumentsHelp.txt"
Once installed on Computer B, the program doesnt display the image because it's looking for "Computer A" in the file path.How do I correct my programming so that the files are universial and can be found on any computer the program is installed on?
I have a project in visual basic 2010 and want to convert it to visual studio 2010 so I don't have to chose the "open with" every time. Is there a tutorial on how to do this?
