VisualStudio 2008 64bit in windows 2008 r2 64 bit oracle does not connect to databas

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :.NET Framework


I am currently using visualstudio 2008 with 3.5 framework sp1 release.

We want to migrate our applications to the new server everything as a 64 bit. which is having the following configuration 

windows 2008 server  R2 64 bit with Oracle as backend.

We donot have any 32 bit oracle client tools installed.I am able to connect to the database by using a console/windows/class library applications

When I try to simply connect to the database(open and close the connection) using either a website or a webapplication.I am getting the following different types of exceptions

Oracle client and networking components were not found. These components
are supplied by Oracle Corporation and are part of the Oracle version
7.3.3 or later client software installation.

Provider is unable to function until these components are installed.
Attempt to load Oracle client libraries threw BadImageFormatException.
This problem will occur when running in 64 bit mode with the 32 bit
Oracle client components installed.

Sql Server 2008 (64bit) on Windows Server 2008 with a connection to Oracle 10g (64bit)



I know there are similar questions posed but none that provided a solution to my particular problem.

I am upgrading a SSIS package from Sql Server 2005 (32bit) to Sql Server 2008 (64bit) on Windows Server 2008 R2. It worked on the Sql Server 2005 machine. This package connects to an Oracle 10g (64bit) database.

The Oracle 11g client and networking tools are installed (by the Oracle DBA). I tested my connection on the sql server 2008 machine using SqlPlus and doing a tnsping. I can also create a Windows ODBC datasource connection to the Oracle 10g database.

The package executes properly on my local computer XP (32bit) running bids 2008.

The package fails on the server in SSIS. I need to be able to schedule the package in a job so it must run in SSIS.

I have also tired to create a connection manager to the Windows ODBC oracle connection without success. It is blank and does not allow me to select or refresh to view the Windows ODBC datasources.

Any assistance would be greatly appreciated. I have seen other forums where installing the Oracle 11g ODAC and Oracle Developer Tools for Visual Studio might assist in creating the package. But I need assistance in running the package from SSIS and not BIDS.






is SQL 2000 32 bit supported on Windows 2008 R2 64bit?

Error while trying to register DLLs for Microsoft Jet on Windows Server 2008 R2 64bit

Hello! I'm having issues with importing Excel spreadsheets into Microsoft SQL Server 2005 on a Windows Server 2008 R2 64bit server.  After browsing the web, it appears that the problem is with the DLL's used by Microsoft Jet.  I've thus attempted to re-register these DLL's.  However, I am receiving the following results. c:\Windows\SysWOW64> regsvr32 c:\Windows\SysWOW64\msjetoledb40.dllSuccessful c:\Windows\SysWOW64> regsvr32 c:\Windows\SysWOW64\msjet40.dllSuccessful c:\Windows\SysWOW64> regsvr32 c:\Windows\SysWOW64\msjint40.dllThe module "msjint40.dll" was loaded but the entry-point DLLRegisterServer was not found c:\Windows\SysWOW64> regsvr32 c:\Windows\SysWOW64\msjter40.dllThe module "msjter40.dll" was loaded but the entry-point DLLRegisterServer was not found c:\Windows\SysWOW64> regsvr32 c:\Windows\SysWOW64\msjtes40.dllSuccessful c:\Windows\SysWOW64> regsvr32 c:\Windows\SysWOW64\mswstr10.dllThe module "mswstr10.dll" was loaded but the entry-point DLLRegisterServer was not found I've set the application pool for this site to use 32bit.  Please note that due to my role on the team, other options such as using ACE are not available to me, unless I can prove that I've exhausted all other options. Thoughts? Thanks,Mike

Help deploying Windows Service to 64bit Server usinf Visual Studio 2008 Setup Project?

I have a Windows Service I created a while back for our Win2003/2008 32bit Servers, written in Visual Studio 2008, deployed via a VS2k8 Setup Project.  Everything works great, installs fine, and runs as it should.  There is no platform dependent code, it's all straight-up .Net Framework stuff, so we thought it should deploy to a Win2008 64bit Server just fine.  But this seems not to be the case.

When I try to install the Service as is on the 64bit machine, the service and associated DLL's are installed to the "C:\Windows\SysWOW64" folder, but when you right click the Service itself and look at the properties, it is trying to find the .exe file in the "C:\Windows\System32" folder. This difference prevents the service from running, obviously.

If I change the Setup Project settings, set the Target Platform to "x64" and change in the File System screen to use the "System (64-bit) Folder" placing the files in there and re-run the setup.exe on the server.... now the files are correctly installed to the "C:\Windows\System32" folder, but the Service itself is not 'installed', that is it *does not* show up in the Services Manager.

Just for the giggles of it I tried to manually install the service using 'installutil.exe' in the .Net Fra

Windows 7/Server 2008 R2 + Office 2010 cannot connect to SharePoint 2010


I have a Windows 7 x64 machine, with Office 2010 x86 installed.  I also have (2) Server 2008 and (2) 2008 R2 machines with Office 2010 x86 installed on them. On all of these machines I can not connect to SharePoint 2010 using Office.  The following occurs:

  • From the browser, browse to a doc lib. 
  • Click on an Office document, select "Edit in Microsoft ..."
  • An "Open Document" dialogue box appears, indicating that "Some files can harm your computer. If the file information below looks suspicious, or you do not fully trust the source, do not open the file.  File Name: Whatever.docx  From: SPServer2010.  (This is the first clue that something is not working properly.  I don't think this would appear otherwise)
  • Click OK.
  • The document opens, but with a [Read-Only] in the title bar. 
  • If I click save, it tries to save to a default location on my desktop computer.

Another example of the problem:

  • Open an Office 2010 application. 
  • Click File>Open
  • In the Open dialogue box, type in the URL of a document lib on the server. 
  • The error message: You can't open this location using this program. Please try a different location.

MOSS2007 (64Bit), Windows Server 2008 (64Bit) & Crystal Reports 2008


Hi guys,

at the moment i stuck at the following problem:
I try to call a Crystal Report (designed with Crystal Reports 2008 SP3) from my SharePoint aspx-page. In my 32-Bit Development-Eviroment everything works fine, but now i'm trying to deploy the solution to a MOSS207 64-Bit enviroment (Windows Server 2008 64Bit, IIS7, MOSS 64Bit).

When i try to call the report i get the following error message:
Exception Details: CrystalDecisions.CrystalReports.Engine.LoadSaveReportException: An error has occurred while attempting to load the Crystal Reports runtime. Either the Crystal Reports registry key permissions are insufficient, or the Crystal Reports runtime is not installed correctly. Please install the appropriate Crystal Reports redistributable (CRRedist*.msi) containing the correct version of the Crystal Reports runtime (x86, x64, or Itanium) required. Please go to http://www.businessobjects.com/support for more information.

I've asked SAP for a solution of this problem and got back two possible ways to solve this problem:
1. Compile the application in 32-Bit mode -> this does not work with SharePoint (Error: Can't find assambly)
2. Run the Web Application in 32-Bit mode -> this does nit work with SharePoint (In

Windows Server 2008 32 and 64bit and Active Directory


By any chance do you if it is recommended to have Sharepoint 2010 and
Active Directory on the same windows 2008 server? Or they have to be on separate servers?

Also, do you know if Windows 2008 32 bit have any conflict communicating
with Windows server 2008 64bit?

How to Import Excel Data into SQL Server 2008(64 bit) Using SQL Query (in Windows Server 2008 64bit

I am developing VB .Net application in Visual Studio 2008(64bit), SQL Server 2008(64bit) and Windows Server 2008(64bit) environment.

I need to import an Excel and Flat files data into SQL Server database using SQL Query. I tried a lot with the following SQL Queries directly with SQL Server Management Studio,

1. SELECT * INTO  dbo.ExcelImportTest FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0','Excel 8.0;Database=D:\PTPLDCT\DCT Test Datasource\DCT_Excel_Test_Sample_1.xls',

While executing i got an error as below,

Msg 7403, Level 16, State 1, Line 1
The OLE DB provider "Microsoft.Jet.OLEDB.4.0" has not been registered.

2. I have also tried with MSDASQL provider,

Select * from openrowset('MSDASQL','Driver={Microsoft Excel Driver (*.xls)};
Dbq=DCT_Excel_Test_Sample_1.xls;DefaultDir=D:\PTPLDCT\DCT Test Datasource\', 'Select * from [Sheet1$]')

Then i encountered the following error,

OLE DB provider "MSDASQL" for linked server "(null)" returned message "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "(null)".

3. Finally i have tried the Query with Linked Server,

Word Automation in sample ASP.NET(C#) application.

I am using Microsoft.Office.Inetrop.Word Assembly for automation. Here I am reading a XXX.dot template file and fill the contents with dynamic data.

When i am executing my code in localhost:someportnumber the automation is working fine and I could get expected result and when I am hosting in my inetmgr(Windows XP is my OS) it is also working fine.

But the problem is that when I am hosting in my production server(Windows Server 2008 Standard Edition) I am not able to perform automation and results in the following error.

Data: System.Collections.ListDictionaryInternal
Message: Word has encountered a problem.
Source: Microsoft Word

The code gets failed in the following line:

ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();

Document wordDoc = wordApp.Documents.Add(ref oTemplate, ref oFalse, ref oMissing, ref oMissing); // Error in this line

I cannot able to proceed further. Can anybody please help me in solving this issue?

No ASPNET User in Windows Server 2008?


I have been looking everywhere online regarding this, but have not found a clear answer.


I have an ASP.Net app running on Windows Server 2008, it's basically a reporting app using Crystal Reports. I have encountered a roadblock in regards to rendering some pages. When I run the app in Visual Studio(on the same 2008 machine) everything works perfectly. Yet when I publish it and run it live the reports will not display correctly, I get a message saying Failed to render page.


I looked this error up in the Crystal Reports website and the fixes they have there refer to giving the windows "aspnet" user full access rights to certain folders on the machine. I would be happy to do this, however there is no aspnet user in Windows Server 2008.


I installed the server and set its role to be Web Server. I also checked all the options regarding ASP.Net and IIS 6 compatibility. Yet there is no ASPNET username anywhere.


Did I set the server up wrong? or do I have to do something within ASP.Net to  create this user and then give it rights?
