After being spoiled for years with C# automatically setting the default namespace for new classes to match my folder structure, I'm wondering if there is any way to get VB.NET to do the same?
I've been aware for awhile that it doesn't do this automatically but I've never really researched alternatives. keep my VB.NET class namespaces in sync with my project folder structures?
Well guyz its been a long time since my last post here but i got some troubles with a new project i am on and the members of vbforums always had the solution So as the title says i want to make a launcher that will sync 2 folders and some files from my Website to my local HDD. Something like that with Api s

i just want to ask if how can i sync my files (like dropbox) via web service? is that possible in vb.net?
View 2 Repliesi'm interested in syncing a remote folder and a local one over FTP but I don't want to use 3rd party components since this is not going to be a public build so I see no reason to invest on something like this now any code snippets or so available?

Namespace Transaction, Document
Class Signer
Public Sub New()
[Code].....
I basically want to be able to instantiate the Signer class from either Namespace. The reason is that I mistakenly set it up in the Transaction class and need to migrate it over to the Document class without breaking existing legacy code. I'd prefer to not have the same Signer class duplicated in both Namespaces if possible.
I want to create SETUP for vb.net window application. My application uses multiple dll.so I want to keep dll in separate folder and exe in separate folder. When I create setup, dll and exe are in same (Application Folder of setup), then it works, but when I create 2 different folder in Application Folder of setup, one for dll and one for exe, then it desn't work. Please suggest how can I ?when I create set up then all goes to applciaton folder. when i installed then all are installed in same folder.but I need all dll goes to sperate and exe goes to sperate folder.
View 1 RepliesI'm new to VB 2008 after having spent a long time with VB6, so I apologize if this is a stupid question. But I'd really like to have this straightened out.
Let's say I have a pretty large structure that has lots of properties.
Code:
Now say that I want an internal database with about 10 instances of this structure total, describing, say, 10 different products that a store sells. When these values are loaded from a database, they remain totally static. (However, they can be different each time a program loads)
Now say that I have a class. Each instance of this class is a type of that BaseProduct structure. Meaning, each instance of the class pertains to one of the 10 types of products that the store sells. However, this class has additional properties that pertain specifically to each instance, which are not static.
Code:
Now, the problem here is... If I have 200 different transactions, each one contains an instance of BaseProduct. BaseProduct is HUGE, and is largely redundant (only 10 types possible), so I think it's a little silly to include a whole copy of it with EVERY transaction. However, the Transaction class really needs information regarding the base product it pertains to. Is there a way to, instead of declaring a New BaseProduct in the Transaction class, to simply make one of the properties of the Transaction class a pointer to a BaseProduct variable?
In VB6, I would accomplish this by making a BaseProduct(10) array, and then giving each Transaction an ID number referring to an entry in that array. But in VB 2008, using class structure, this is impossible. I can't define the BaseProduct(10) array outside of a class in a namespace, and if I define it in the actual application's form, then the class loses modularity since it relies on the application that's using it.
can we unzip a zipped folder using microsoft APIs or namespaces perhaps System.IO.Compression. However, it seems to be cumbersome to use them. With a thrid party dll file it works perfectly fine, however i dont want to use it as we dont know what is actually happening inside. Can we have a piece of code which unzips a zipped folder.
View 3 RepliesIs it possible to have a single class reside within two name-spaces and how can I do this?
To clarify: We have a class library (let say root namespace is classLib1), which has grown over time (more classes) and I want to logically group classes into different namespaces. However some of the older classes need to be grouped into these new namespaces (e.g classLib1.section1) and doing so will break legacy code in other assemblys that use this class library. So I want to be able to refer to a class using both name-spaces until we can phase the old ones out.
I can't find any information on this, which suggests there is a reason that people would not want to do this!?!

I'm sure there are several ways of achieving my goal but I am after opinions on what you think is the best option. I'm writing a vb.net application which (amongst other thinks) interfaces with media players in the home. Because there are different types of media playersI'm trying to structure it so each type of media player has it's own class which interfaces to a management class which sits on top of all the different devices types.
The device classes are responsible for discovering the phsyical devices and returning that information up to the management class. A device class may be responsible for monitoring 1 or more physical devices so..

I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

Currently, if I have different classes containing functions etc, I would structure them all in the 1 VB file titled whatever the main Class is. For example:
[Code]...
However, the problem with this is the file can become 1000s of lines long making hard to find portions of code. Is there a way I can store SubClass in a file such as MainClass.SubClass.vb so that its easier to locate classes? Or is there a better, more standard, way of doing this?
I've got an application that takes the files in a folder structure and publishes them to another location. Currently it goes through every folder/file and compares the dates in the source and destination. If the file doesn't exist in the destination, or is older, then it copies it across from the source. It's obviously foil proof, but not as fast as it could be.
Ideally, I'd like to create an audit (or audits) saying what the current state of play is in the destination and compare the source folders/files against that instead.
This of course assumes the destination isn't messed around with manually, but I think that's a fair limitation.
So has anyone got any suggestions for how this audit could work? ie: How I could store data/values, such that on the next run when I look down the source folder/files I could compare it to the audit and see 99% of the files are unchanged, so only send across the X new ones etc?
ps: I don't suppose there's a valid (in Windows) that can tell you the date any file in a folder was created/amended? ie: So rather than checking down 200 files to see their individual dates/times, if I could get a single folder level value saying the date of last update/create, if it hasn't changed since the last run, there's no work to do! There is GetLastWriteTime but this doesn't seem to get updated if you amend/update a file, rather than creating a new one!
Below is a tiny program I modified from an example Microsoft code tutorial. This program simply copies .flac and .mp3 files from one specified folder to another, and if the file is already there it simply does not copy the file. I would like to make 2 changes to the program:
How would I go about making the error handling work (i.e. not crashing the program when an invalid input is made)?Also, a big change I would like to make would be for it to copy the folder structure and all files in the original folder (At the moment, it only copies files that are directly in the original folder, not files that are in folders inside the original folder).

View 3 RepliesThe question: better a deep folder structure or less subfolder with thousands files?
The problem: I have a VB.NET program that generates around 2500 XML files per year (circa 100 KB per file).I have to store the files on a file server (Windows 7 or NAS).On the network there are around 30 PCs using that program.I am looking for the best way to plan the structure of the folders on the file server with the goal to have a good human-readable folders structure and at the same time a fast access to the file.In the past I made a similar program with the following structure:
fileserverPC1yearmonthsfile00001.xml
in other words a folder for each PC on the LAN
then a subfolder for the years
then a subfolder for the months[code].....
this solution would produce a clearer folder tree, but more files per folder.I do not know if this could be an issue in term of speed by file accessing with vb.net programs or other third hand application.
I want to copy files with a specific extension (for example .config or .exe). It should create a structure of nested directories, and then insert each file into a specified place in the directory hierarchy. Ideally I would just specify a parent directory for each file and a parent directory for each directory and it would build it.
I need any existing utility or batch file or power-shell script or C#/VB .Net code to perform this activity.

View 5 RepliesThis is purely a coding practice question concerning VB.NET structures. Where do you keep one?As an example, I've created a structure for the simple purpose of keeping information organized, I'd like this structure to be stand-alone, not belonging to any class so I wouldn't have to access it through SomeClass.MyStructure but rather simply MyStructure. So, do I keep it in a separate class and import it into my namespace? Do I keep it in a module (Static class, essentially)? Do I just make a separate VB.NET code file and place is there (I would like it to live in a separate file). Just to clarify, I need this structure to be accesses by the whole application, not just a single class.

' target gets properly set to something of the desired type
Dim field As FieldInfo = target.GetType.GetField("fieldName", _
BindingFlags.Instance Or BindingFlags.Public Or BindingFlags.NonPublic)
field.SetValue(target,newValue)
This snippet works perfectly IF target is set to an instance of a CLASS.However, if target is set to an instance of a STRUCTURE, the code does not actually change the value of the field. No error, but the value remains unchanged.And, oddly, if I'm stepping through code, watch the SetValue fail to do anything, and immediately go to the Immediate window and type exactly the same SetValue operation, that works.

View 2 RepliesI have this application that users can make exams that contain exercises of different ... whatever. Anyway when student takes the exam he chooses it from a list and then all exercises are loaded from database. I wanted to make loading process faster by loading only first exercise data and putting others in background thread.
Actually in other parts of this application something like that is done but not by me. Basicaly an api class is built around BackgroudWorker and i can use this class to put certain functions of objects to be executed in background. The idea sounds great but in real life there are some problems with it. For example for historical reasons this application uses global functions and reader and uses global connection to Access database which means if in background something is being fectched from data base and you try to fetch from database in main thread then a „reader is already open" error occurs. To avoid this error if im doing something in main thread and want to fetch some data i have to move my function from main thread into background worker function list. And basically this in my opinion stinks cuz you end up with many delegātes, invoked checking and thre result... I was just thinking that there maybe is another way to allow (maybe with events) not put everything in background in case something is happening in bakcground but rather allow bgworker to finsih current thing, then do my thing and then resume bgWorker and not create havoc in code.
Basically i have to classes - exam and exercise that each implement many interfaces (like IExercise, IExerciseResult, IExerciseYesNo, IExerciseMultipleChoise etc.)And then i have DataBase classes like ExerciseDB, ExerciseResult etc. That have functions that preparē the sql params and call sqlHelper functions.And for example when i load up exam i go throug all exercises and call LoadData function that in turn calls ExerciseDB function selectData and then i put the returned data in Exercise object. And this type of thing of course would producē error if i at the same time would try to register the answer in database for another exercise. Ofcourse i could always check and put this in background... but as i said i'd rather want to work with database from both threads.
