I have a field in a SQL Server 2005 DB of type 'image' that contains documents, mostly pdfs. When I view the field in the database, it looks as though the data is stored as a hex string. I have extensively googled and came up with the VB.net function below to convert the field to an actual file, but it only outputs a file containing the string of hex characters rather than the file that the field is supposed to represent.
This is a sample of the fields' data (I have truncated it for privacy purposes):
[Code]....
And is it possible to open the file straight from a query in SQL server?
I'm trying to zip a file that is stored on SQL Server as a blob image field and when downloading the zip file it says the file is corrupted.. or the file will open but contains some crazy characters. I've tried WinRAR and 7zip and no luck. I checked out [URL] and tried to kind of combine the browser attachment code and the memorystream/byte array code and no luck.
Here is my code snippet: Try BinData = DirectCast(dt.Rows(0)("ImageField"), Byte()) Catch ex As Exception End Try Dim blen As Integer = BinData.Length [Code] .....
how to store CSV & Text file to an Image Field in SQl table. the table is using by some other application that's why i could not change the field data type.
I'm making a front end to dvdauthor.I have a picturebox which holds the menu background. In order to draw a textbutton on the background image I store the image in a hidden picturebox. So the text doesn't get drawn to the visible background.
Dim ctl As Control For Each c As Control In pbMenu1.Controls If c.GetType() Is GetType(TextBtn) Then[code]...
This works the first time. But if I hit save again it writes the text to the background image on pbMenu1.
I have a client/server application set up that the client sends a word file to the server and then the server converts that word file to a .TIF and sends the image back.The stuff I have now works.Say if I sent the size of the file and the actual file byte() to the server back to back, would the NetworkStream contain both back to back? This what I though would happen. So I implemented a kind of 'turn' based interaction during the duration of the conversion process.

tried using the application settings yet. Everything seems to work well except when I specify the type as a string collection. When I try to add new items at run time using the property window I get the following error:Constructor on type 'System.String' not found.Do I need to do something else to make this work?
I have a class called CookieMonster, its objective is to simply create a cookie based on 3 parameters passed to it. The cookie name, the cookie name-value pairs and the cookie expiry date.I have experimented with List(of T) and Array and StringCollection, but I'm unsure which is the best for passing the name-value pairs and providing that information to the class.Ideally, I'd like to be able to do something like this:
Dim l As New List(Of String) l.Add("name", "value") l.Add("name", "value")
I am working on an application that pulls a field from a SQL Server table that has numeric values separated by commas, for example (1, 3, 4, 6). I need to load this field and somehow load it into a numeric array. However, I can't seem to come up with a good solution. Here is what I have tried:
Dim PagetoSign as Integer() PageArray = Split(_DataRowView("PagestoSign"), ",") Dim _PagetoSign As String = ""
[Code]....
However, I receive an error message when it enters the for each loop. I'm not married to this method if there is a more elegant way.
Normally, I'd choose List<String> [or, in VB, List(Of String)] over StringCollection whenever possible: see also Best string container.
However, as it seems, generics — and hence, List<String> — are apparently not supported in VS 2008's settings designer. Therefore, if I want to use a list of strings in my user settings, I have to resort to using a StringCollection there.
Now as I don't want to see StringCollection throughout my code, I need to convert it to List<String>. How do I do this efficiently? Or, even better, am I mistaken and there is a way to use List<String> in settings designer?

I know how to insert a new row into a table that has a binary column. But is there any way to update the binary column once that row has been added? So far an exhaustive google search has turned up nothing. Get the current row that I wish to update delete the row that I wish to update Create a new row with the information from the row I wish to update plus the new binary It just doesnt seem very elegant, and I was hoping I could do the same thing with an update statement. Here is the updated code I am using now for reference
