Im doing a FileStream.Write to create a file on a local computer from a file I download from the web.
qq1 =>how can I change the version property of the file after writing it or while writing it?
qq2 => and how can I check the version property of the file?
How they relate and differ from each? What are the best practices for version control? Is there a primer about publish online? Or a good book?
And is it possible to make ClickOnce and a msi in one solution of VS 2008? If so, is there any conflict or pitfall?
BTW I am using VB if that makes any difference.
I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

I know, not the ideal environment for games. However, I do love VB.net and would like to try.Currently, I am creating a console version of a roguelike (hack/slash ascii adventure) and need some help with the theory. The implementation I can handle.
In the game loop, if I redraw the map every time an action happens, there will be an awful flicker.Should I: a.) set up movements so they rewrite the area the player was at, and then write at the tile the player is going to
b.) use WPF and use the canvas
c.) insert your better solution?

This runs on Windows Server 2003 and XP. I've tested it on those systems. But will that run on Windows 7, Vista, 98, 95, NT, 3.1? If not, which language/version do I need to use to do the same job on each system, and could you point me to the language reference?
Following on from my last question, are the AssemblyMajorVersion, AssemblyMinorVersion,AssemblyRevisionNumber and GenerateRevisionNumber properties required in .vbproj files?
All of our components have these entries in the .vbproj files but they are completely out of sync with the AssemblyVersion and AssemblyFileVersion entries in the AssemblyInfo.vb files.
Are they a legacy from the upgrade from previous VS versions?

I have an INI file built like this:
[registration]
key=<key goes here>

and using a registration system (found in codebank here), I'd validate it like that. I just need to know how to read and write from it. All the ones on google are too vague, or focus on the wrong part.
I'm running several different automated processes and when I get done with them, I show the results in a form with various controls.
In this form, I use Panels, Labels, TextBoxes, and TreeViews, and ListViews to display a wealth of information.
When the automation part is done, I want to be able to log this info and save that log file on the User's PC.
I thought it would be best to make a custom file extension and then hash it with MD5.
I'm pretty sure I can get all of that done. The problem is that I'm not sure how I would load that info back into the application.
Since the log files will appear on a seperate form, I can't just load the data back into the original controls.
Would it be best to create a blank template of controls and then load the data into those controls? Or is there a way to save content "as is", controls and all?

View 2 RepliesI have 10 parts of a file. Each part is 10,000 bytes.Now say I receive these parts out of order meaning I cannot simply just write them in order as I receive them, but I am able to detect what part it is.
If I received part 3 how would I write those bytes in the 20,000-30,000 byte section of a file?
i have 6 text boxes on a form the contents of which changes depending on a list box, i also have a button which will be used to create a log file, my question is how do i write the contents of the 6 textboxes to a new text file, and on separate lines in the txt file when the log button is pressed.
EDIT: preferably also needs to use the save file dialog so user can choose file name and location to save to.
I coded in it along time ago, back in middle of the 90's, but not heavily, so I don't remember that much, and never really worked with databases or file import/export. I'm trying to write code in to take my table or recordset thats active and export it to a XLS file.

I have a file.txt on my website,How do i write to this file thats on my website ?
Like write a line at the end of the file without overwriting any lines thats already there.
I'm amazed at this situation. In QBasic, you could just easily GET and PUT whatever you wanted at the exact position in the file that you wanted. Now in Visual Basic 2008 I'm just completely stumped.
I can't use FilePut or FilePutObject because of a twisted issue. It adds a couple of bytes to describe the length of the data being written: what's the point of BINARY read/write if it won't allow you to write EXACTLY what you want and nothing less or more? There's a way to turn off this issue, and that's by setting the parameter StringisFixedLength to TRUE, but that's where the twisted part comes in. You can't do that. As far as I can tell you have to redefine the function using SUB, for example:
[Code]...
My.Computer.FileSystem.WriteAllBytes. To my amazed surprise, this function doesn't even bother to include the possibility that I might want to put the data in a specific position within the file! I can't believe this. You can either specify to APPEND at the end or not, in the latter case apparently resulting in a write to the beginning of the file. No option at all to specify where in the file you want to put the data. I can't believe this.
How do you write to a SPECIFIC position in a binary file in VB 2008, and do it without the program deciding to add a few "informative" bytes to your data before it's written (totally undermining the whole point of binary files)?
I am trying to use the BGW to save a DGV to excel file, but don't know how to do it correctly, specifically setting the savefile name this code doesn't work gives me:
'System.Runtime.InteropServices.COMException' occurred
- Make sure the specified folder exists.
- Make sure the folder that contains the file is not read-only.
- Make sure the file name does not contain any of the following characters:
Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process. I also tried doing the Save in the BGW RunWorker Completed event but then there is no file name. It seems I need to pass the file name the user inputs in the SaveFileDialog to the BWG WorkerCompleted event somehow
