Open Is Not Declared - File I/O Functionality Is Available In The Microsoft.VB Namespace
Jun 25, 2011
I have downloaded and installed Visual Basic 2008 Express Edition today, as my hard drive that had Visual Basic 6.0 is getting old and was nearing the end of its life cycle. I have a new CPU as of yesterday.Anyway, now that I have Visual Basic 2008 Express Edition installed, I am working on converting the code from my Price is Right game to VB2008 Express code.When I used this code in 2008 Express...
Private Sub GetNames()
Dim x As Integer, tmpstr As String, tmpstr2 As String, tmpstr3 As String, tmpstr4 As String, tmpstr5 As String, tmpstr6 As String, tmpstr7 As String, tmpstr8 As String, tmplng1 As Long, tmplng2 As Long, tmplng3 As Long, tmplng4 As Long, tmplng5 As Long, tmplng6
[code]....
I got a message saying "Open is not declared. File I/O functionality is available in the Microsoft.VisualBasic namespace."
This is probably a pretty novice design question. I'm trying to work my way through a number of requirements and give the users the experience they're looking for.I've written a tool that does big calcluation-type things. It currently consists of a class library and command line tool (separate .NET projects.) We're using an Access database format as the file type because it can keep all the various tables together in one file. A few other items about the application: There are not many users. There are no concerns with scalability. There are not great concerns with updates. Desktop is desired. Not web.Using VB and .NET 3.5 SP1
I now need to develop a GUI front end that will allow typical File/Open and File/Save type operations.Users expect that they can open a file, edit it some, then either choose to save it or close it unsaved without any changes being written back to the file. Saving it would obviously save all changes affecting all tables back to the file.
Does it then make sense to use a temp file for something like a proxy then? To, when a user "opens" a file, copy the source Access file to a local temp file and then use that for the editing session? Then, if the user "saves", copy the local temp file back to the source path?
Update: [tagged with ms-access tag too] Also, I omitted the fact that users would expect typical File / Save As functionality too. I think the design I've put in question in this post is what is traditionally called the Proxy design pattern. Has anyone tried this (successfully!) with Access database files before? Words of caution or advice?
i want to select specific nodes of a xml document.Everything is ok until the document has an xml namespace. Then when i try to select the specific nodes no node is being returned.. This is because an xml namespace is declared. Is there a way to select those nodes and ignore the xml namespace ?
I'm using old DAO 3.6 to connect Access database (with mde extension). App works fine on XP and on Win7/Vista when UAC is low/disabled. But when UAC is on I get following error: The Microsoft Jet database engine cannot open the file 'C:ProgramDatacompanydb.mde'. It is already opened exclusively by another user, or you need permission to view its data. [code]
i'm pulling my hair out on this one. the error i'm gettting is: The Microsoft Jet database engine cannot open the file ''. It is already opened exclusively by another user, or you need permission to view its data.
I have a WinForms application that I have taken over support for and it was build using Visual Studio 2005 with VB.Net. The application makes use of an Access database. It runs fine when it is installed as a standalone application, but the install cd for the application also allows for a network install and this is where I am currently encountering issues.
To test the network install I created a folder on my server (Windows Server 2003 SP2) and copied the Access database to this folder. I created a share for this folder and gave everyone full permissions to the share. Then on the workstation I installed the application and gave the path to the database as follows:
\myservermysharemydb.mdb
(The install steps here are as per the instructions given on the installation cd)The workstation that I installed it on is Windows 7 Ultimate. When I run the application, I get the error message given in the title when the application tries to read the database file. I have confirmed that I am able to write to the shared folder on the server, so I don't think this is a permissions issue. Also, the database file is not in use at all, so it is definitely not opened exclusively.
UPDATE:I have tested the workstation installation on a computer with a fresh install of Windows XP SP3 and it is able to access the database file without a problem. So it seems that this error that I am getting is somehow specific to Windows 7. Is there maybe a known issue with Oledb drivers on Windows 7? My version of Windows 7, btw is 32 bit.
I read in msdn that registrykey class is found in Microsoft.win32 namespace.But when I try to add a reference to my project, I couldn't find Microsoft.win32 in the list.
Error msg - Namespace or type 'Data' for the Imports 'Microsoft.ApplicationBlocks.Data' can't be found. How do I fix this error. I tried adding a reference but it is not listed in the references.
I need to export the contents of DataGridView into an Excel file. There is lot of discussion which I went thru and leaves me more confused now than before. I am using VS 2010 Express with Office 2007.
In the VB project reference components, I looked for Office components and did not find it there.
i used printForm to print forms, but when i installed the powerpack 3.0 it doesn't work anymore.i am always getting an error "PrintForm is ambiguous in the namespace 'Microsoft.VisualBasic.PowerPacks.Printing'" i am using visual studio 2008 professional edition.
I have a project which opens a simple Excel file and populates it. It was working fine until this morning, when it has suddenly started giving me the error above: 'Application' is ambiguous in the namespace 'Microsoft.Office.Interop.Excel'.I haven't changed any project references, or anything within the file itself. The references include Microsoft.Office.Interop.Excel. The imports statement is there: importsMicrosoft.Office.InteropThe object declaration is also complete: Dim xl AsMicrosoft.Office.Interop.Excel.Application which is the line that's giving me the error!
I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'. ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then IndexOutOfRangeException was unhandled Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.
I've started to use a Vista machine for development. In case it is significant: I'm using MSBee so that I can code in the Visual Studio 2005 IDE while still building against the 1.1 framework.On the Vista machine, when I tried to build a particular vb project, I got this error:
error BC30464: Namespace or type'Compatibility' in the project-level Imports 'Microsoft.VisualBasic.Compatibility' cannot be found.
The same project built fine on my old XP machine. I checked in this folder on my Vista machine:
C:windowsmicrosoft.netFrameworkv1.1.4322
...and sure enough, "Microsoft.VisualBasic.Compatibility.dll" was missing. So was "Microsoft.VisualBasic.Compatibility.Data.dll". Copying them from my XP machine to my Vista machine allowed me to build the project successfully.I'm just a bit puzzled as to why this happened. Why was "Microsoft.VisualBasic.Compatibility.dll" missing? I'm also not very comfortable with my chosen solution - copying the DLL manually. It works, but surely there must be a better way.
We have developed a tool using VB.net and in one screen, we have placed a button - 'Contact Us'.
The business intent of this button is to - send query regarding technical help to our team. Once the user clicks on the Contact Us button, microsoft outlook new mail page should open where the mail ids of our team should be populated by default, the user jus has to type the subject and the body and send across to us.
I've installed Mic Visual Studio 2008 few days ago. At first, Mic Visual Basic functions very well. But now, i can only open the program, but not the form. When I wants to Open>New Project, something pops out shows that "No Visual Basic Template can be found. See the Application Log in EventViewer for more details."

I am working on a project where I need to open microsoft word documents in a form with a panel (the document will be put into a panel).I found the code to try and use API, it would not recognize the file names (yes they are valid filenames).Tried a whole bunch of stuff. Here is my current incarnation:
Dim pi As New Process Dim i As IntPtr pi.StartInfo.FileName = FileName[code]....
It ALWAYS starts the word document in its own window and will not redirect it to my own program.I tried to redirect the output and it gave me a message that it was not a valid win32 application.
I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:
[Code]...
How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?
ow can open word document inside the "Microsoft Web Browser" control using vb.net.Word document open inside the "microsoft web browser" control by using VS 2008,vb.net, office 2003 and Win Xp. but it is not open inside the "microsoft web browser" control by using VS2008,vb.net office 2007 and Win 7.
