I have an ASP.NET site in a web server and the images are stored in NAS (some kind of lacie external storage), I tried UNC and other things but no success.how can I access images from external storage in ASP.NET
Update: The images are reachable from the server but when I try to access in ASP.NET throws me error.
I am trying to come up with something that will let me obtain a unique ID of some sort for most types of storage devices. These can be USB thumb drives, SD cards, external hard drives, etc.
I have run across this:[code..]
But I can't find anything similar within .NET. Can anyone point me in the right direction?
My end goal is to be able to define specific hardware storage devices, and then have my application auto-detect them when they are plugged in.
I'd like to move my images / icons and wav files (basically, almost all of my internal resources) from an existing project (VB 2005) and put them in an external dll, then reference this from my exe and call the relevant resource as required.
What would be the best way of doing this?I understand that I should create a ClassLibrary and put my resources in that, but how should I expose those resources to an external program and how should I reference and call the dll from my exe?
I've done some searching, but not found anything that seems to explain the process adequately enough.
I have a client who wants his custom-written CRM to be able to access his sales people's emails so that, effectively, a history of email conversations between customer and salesperson is stored inside the CRM's database.
The CRM is written in VB 2008 and the database is SQL Server 2008. The only email these people use, in the shop and on the road, is GMAIL. Each sales person has their own GMAIL address. Thats how they operate.
If they're on the road and respond to a customer's email inquiry about a product, they would like that email conversation to be stored in a table in the database. I think thats the part I cant wrap my head around. How to get access to the email data (knowing the user id and password) and doing so from VB 2008
Update: A free or close to free solution would be preferred.
I want to package and deploy windows app which has images in allimages folder,resource folder is also generated that refers to all images in my vs 2008 application.I have calc.exe

I am quite green to VB .NET and it start occuring to me that I am doing things probably in a very ineffective way.Anyway here is the problem I have datasets, consisting of integers there is set 1 which is of format ID, ID2 - ID here is unique but different ID can refer to same ID2. Before I start reading in the data I have unknown number of these entries (ID and ID2 can be at least as high as 99999999)
Then I have a second data set of format ID2 here is the same as in the set 1 and it can contain several PID entries (all integers). In this set the ID2 is unique and again for one ID2 there can be unknown amount of these PIDs, same PID can occur more than once.

I'm opening this discussion up primarily because I felt that it was inappropriate that Samir Ibrahim and I had hijacked another thread by turning it into a collaborative development thread. This thread will also hopefully serve as a searchable reference for those few who actually make an attempt to search the forum for information before posting a question. For reference the original thread I mentioned is [URL]
This thread is meant to be a repository for our continued collaboration on trying to find a way to update the attachment field using the OLEDB class. Samir believes that he is close to cracking the secret code.:)
Attachment retrieval and updating is a fairly trivial task using the Microsoft Access Database Engine. It is also fairly trival to retrieve the attached files using OLEDb as well. The difficulty comes when trying to add or delete an attachment with OLEDB.
The attachment field is actually a record set where each record consists of six fields. One of these fields is the data field that contains the binary file data. According to the documentation, Access will compress certain file. It appears that compression/decompression is handled behind the scenes so to say and what you are present with is sequence of bytes. The data field consists of sequence of header bytes followed by the actual data. The first four bytes define an offset to the start of the data. One thing that we are trying to determine is the meaning of other bytes in the header.
I have uploaded a sample project at: [URL]
This project is by no means a finished product. It is hard code to retrieve the first record from the included Access database.
I'm just getting started with Visual Studio (2005), and my aim is to write a fairly simple application in Visual Basic that will need to store some data to disk.What I really want is to be able to send the application to the end users (xp, vista, win7) and have them just be able to use it without having down download all kinds of extras. For example I'm guessing that if I use an SQL database in my application they will need to download SQl server express or some other sql downloadable?
If so is there a similar downloadable for MS Access?I'm just in the 'seeing how things work' stage at the moment and I don't want to waste time going down the SQL track just to find it won't actually work unless my users all download SQL to their machines (which they won't want to do).
I have a DLL that I made in FORTRAN to do some number crunching. It works in VB6 and in VBA within Excel. But I cannot get it to work in VB2008 or VB2010. If I try to access it the subroutines in the DLL I get either, 1) Structure of DLL invalid error or 2) Cannot find the DLL error.
Here is my VB2010 code for a smaller demo app that came with the FORTRAN development system. Again, this works with VB6 and VBA but not with VB.net

View 1 RepliesMy current solution consists of several Class Libraries and a Website. I'm in the process of globalizing the application and I realized that my resources need to be accessed by all the projects not just the website so placing my resources in the App_GlobalResources folder didn't work. I added my resources to one my class Libraries and now I'm trying to figure out what the best way of accessing the resources are from my markup. When my resources were in the App_GlobalResources folder I was able to access them by using an expression such as this: <$ Resources: MyApp.Name %> for server controls

I'm using access to replicate something that is very simple in excel. I have one "due date" column, and I want the cell right next to those cells to tell me if there are less than 15 days to that date. In excel is a simple conditional function, but I want to do it in Access because it looks better.I'm new to access and even though I've been reading some posts and forums I haven't been able to pull this out. I tried to program a macro with the following
Sub Alarma()
[Alarma] = IIf([Fecha de vencimiento] - 15 > Date(), " ", "Faltan menos de 15 d�as")
[code]....
It shows the following error -> Compilation error: External name not defined.
So, it's not reading the "Alarma" field... how do I define this field? It's inside a formulary, and Alarma is the title (I downloaded a template from the internet and changed the titles so I wouldn't have to do it from scratch...)
I'm writing small VB.Net app which should build reports based on data gathered from some external MDB-files (Access 2007).
It was planned that this app will use parametrized SQL queries to collect data from DBs.
One of the parameters for these queries is path to the external MDB-file.
Here goes sample code:
Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:TempTemp.mdb;")
conn.Open()
[Code]....
Looks simple but doesn't works. After launch my app throws following exception - System.Data.OleDb.OleDbException: Disk or network error.
Have spent a whole day to make it work with no success. What have I done wrong?
I am using Visual Basic 2008 Express Edition. Some of the programs I am writing make extensive use of External files (saved games, data, item lists, etc.) I could use an easy way to get these files to ride allong during deployment (cd mostly). adding them to the resources works for some static pictures, but custom structures into lists of info to read and write from are beond that features abilities, same with the settings feature. I have found in other help referance to "MageUI.exe" so is downloading a .net SDK my solution or is there a better trick I can use?

I'm developing a program in Vb.net + Access DB, and I need to insert images in the DB.
What I've done for picking images is:

I have a Windows 2008 IIS web server that runs an online application. The applications runs on a local SQL database. Images, however, are not stored in the database. The images are stored in a separate folder on the web server. When I run the application on the local LAN, I just use a standard UNC path to access the folder with the images. I want to start running my application over the internet. I can't use UNC paths over the internet.
how can I access this shared folder with my VB.NET program over the internet?
