.net - Unable To Open .DBF Files In Windows 7 That Had Worked Under XP

Dec 20, 2010

I have a VB.NET application that will let me preview .DBF files that come in from some of our clients. The application then attempts to spit out a CSV from this file that we can then use in our various environments. This application worked under Windows XP 32 bit. Our company recently upgraded most of us to Windows 7 x64 which has caused this application to fail. I verified that the target build for this application is x86 and not "any CPU" and rebuilt the app but same issues occur.

It originally used System.Data.Odbc and connection.ConnectionString = "Driver={Microsoft dBASE VFP Driver (*.dbf)};SourceType = DBF;SourceDB=" & dbfSourcePath & ";Exclusive=No; Collate=Machine;BACKGROUNDFETCH=NO;".
The location of the failure is at connection.Open(). The error given is: "ERROR [IM001] [Microsoft][ODBC Driver Manager] Driver does not support this function".

I noticed that the drivers for VFP were not installed and that the Access DBF drivers did not work similar to the post here. The fix listed there is to install VFPro SP2, however, we do not have any FoxPro installs to install a service pack on top of. I then tried to install the OLEDB driver for VFP 9.0 and am now using System.Data.OleDb and connection.ConnectionString = "Provider=VFPOLEDB.1; ourceDB=" & dbfSourcePath & ";" but it now tells me that the connection.Open() line has this error: "Feature is not available".

I am at a complete loss as to how to get this application to work under Windows 7 x64. Below are the 2 variants of the code with the file open path removed for readability (I have verified the path and file exist):

ODBC version:

Imports System.Data.Odbc
Dim strSelect As String
strSelect = "SELECT * FROM " & dbfSourceName

[Code].....

How can I use either an OLEDB or ODBC connection to open these .DBF files under Windows 7 x64?

VS 2010 Open Multiple MP3 Files In Windows Media Player?

Jul 18, 2010

I'm creating a kind of 'playlist manager' application where the user can create his own music playlist and then play it from my application. However, I don't want to give my application any playback features itself, as there are already so many media players around. Instead, I just want to open the files in the current playlist in the media player of the user's choice.

I have a list of MP3 files (their filenames), how do I now open these files simultaneously in, for example, Windows Media Player? I can get it to play one song, using this command (and Process.Start)

[Code]...

Surely this must be possible? You can open multiple files in windows itself simply by selecting them and opening them at the same time. I'm pretty sure the filenames of the selected files will then be in the arguments of wmplayer so that it can open them, but I just don't know in what format.

Asp.net - Unable To Open .pdf File In IE8

Feb 28, 2011

I've posted this question in asp.net web forum but no one replied.

I can't open "ONE" page of .pdf file using IE8 and give me an error message "the file is damaged and could not be repaired" when retrieved from SQL Server 2008, but more than one page I can open with no problem.

With Chrome I can open any number of .pdf pages.

The same page that I can't open using IE8 from DB, can be opened directly from hard disk using IE8.

My code in .asxh file:

context.Response.ContentType = "application/pdf"
Dim strm As Stream = ShowNewsImage(imgName)
If Not strm Is Nothing Then

Unable To Open Data Source?

Dec 21, 2009

I have installed all of the patches and Hotfixes that I can find and truth be told, this is so enigmic that i dont know where to go to.I have been working on a project for a year and just recently I went to add a database (data source) and the Tab was gone. I thought I did something wrond so i went to Data -> Data Source and nothing happens. whats funny is that I cannot do what I want and add the datasource.

I also have VS 2005 installed (which I am forced to use) and here I have no problem.

Can anyone or does anyone have a simular problem and a resolution??I really would love to use all that is available in VS08 and not having to use a much older version...

Unable To Open [Design] View

Apr 16, 2009

So there I was working on a project. I was putting the finishing touches on the GUI and clicked on the Image list I had added. VB froze up a moment, and when it came back I was on a code view of the form showing the properties I had just set up in the GUI. Suddenly, I can in no way view the form. I get a View code option, but no View designer. If I close out the project and open another, there it is "View Designer" right where I expect it. But in the project I was working on, it is just plain gone.

Is there something I am missing here? Can I recover my project?

If I run it in the debuger the whole form shows perfectly, I just can't get to it to edit it.

VS 2010 Unable To Open A New Project?

Mar 22, 2010

Having just downloaded the Visual Studio 2010 Ultimate Beta, I decided to code from scratch a little project I coded under 2008 VB.Net and see how it goes. However, when I click on "New Project", select new Windows Form Application project and try to open it, I get the following error dialog box & msg:

"Unable to cast COM object of type 'System.__ComObject' to interface type
'Microsoft.VisualStudio.Editor.Implementation.IVsGlobalUndoCapableUndoManager'. This operation failed because the QueryInterface call on the COM component for the interface with IID'{305E8709-55B7-4732-B872-1C073AB58047}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."

Anybody have any ideas what's up here, or should I post this in a different area? I tried posting this in the Microsoft MSDN Visual Basic IDE Forum but so far I have not received a reply.

Unable To Secure/lock Down A File That Is In Use/open

Oct 4, 2011

I am writing a program that acceses a file in VB/Visual Studio 2008 on Win7 and running it as a user who has admin credentials. I am opening the file with the following code:

Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None) To test to make sure I can't access this file, I tried to open it with Notepad and I was able to and got no errors. I wrote a new value using Notepad and even saved it and I didn't get any errors form Notepad or my VB program.

I then went on and treid to open the same file twice from my VB program as:

Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None)
Dim Input2 As New FileStream("C:FileTest est.txt", FileMode., FileAccess.Read, FileShare.None)

And I receivded an error in my VB program as expected. So the FileShare.None switch kind of works. Although I was still able to open the file with Notepad while my VB program had it open. I was aslo able to open Windows Explorer and reame it and even delte it while my VB program had it "open", in the write mode no less without my VB program knowing anything about it.

Why are other applications able to ignore the FileShare.None switch? Seems pretty useless if that's the case. And a huge secruity problem

VS2010 .NET And Windows 7 Access Denied On Writing To Or Creating Files In Project Files Folder?

May 22, 2012

Ok I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.

After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.

So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.
