Deployment :: System.Data.OracleClient Requires Oracle Client Software Version 8.1.7 Or Greater
Apr 10, 2009
i was under the impression that using the System.Data.OracleClient namespace will allow me to deploy my application without having the client machine install any OracleClient software besides the .Net Framework 2.0 which if i'm not mistaken, contains the System.Data.OracleClient.dll.
but after creating a WinForm application and then publishing it thru ClickOnce , i found myself getting this error when running the application on the client machine. is this a normal behavior or did i do something wrong in the process?

I have a web site that I developed on Vista using Vb.net9. It makes a connection to Oracle. for the connection I use System.Data.OracleClient. It works fine on my machine, and our test server, but it does not work on the production server. We installed the Oracle Client 11 on the server. The error is System.Data.OracleClient requires Oracle client software version 8.1.7
We've tried, making a console app that opens the connection, connection runs fine, opens, displays a message and all is well there.Then we make a simple web form, put it in the directory of the program, just a button, opens the connection, try..catch, grabs error, same error.The console app was running under an Administrator, web site running under iwam. Is it possible that iwam has a different path?

Trying to insert 315K Gif files into an Oracle 10g database. Everytime I get this error "ora-01460: unimplemented or unreasonable conversion requested" whe I run the stored procedure. It appears that there is a 32K limit if I use a stored procedure. I read online that this does not apply if you are doing a direct insert, but I do not know how to create the insert string for a Byte Array. This is a thick client running on the server so not worried about SQL Injection attacks.

I have developed a windows application which connects to Oracle Database and upload and retrieve data (using System.Data.OracleClient). It is working fine in my developement system. When I build a setup and deploy in another system, it is giving error that Oracle Client is missing.
Do I have to install Oracle Client in the client system to run my application?
(When I visit Oracle site for Oracle Client, it is asking me to download a 200 MB file)
Is there any other way to do this with out installing Oracle Client in the client system?

I have a windows service written in .NET 2.0 that will run every 5 minutes and executes bunch oracle SQL/PLSQL scripts based on time/validation, it throws the above said error some times against some SQLs, the same SQLs run fine at later point without any error, I have no idea what is going on with the app. I am not sure if this has any thing to do with oracle connection pool as I am properly closing the connections after every SQL execution.

I am constructing a search function in a class to be used by several of our asp pages. The idea is simple, take a search term from the user and query the database for the item. Currently I am doing this the wrong way, which is vulnerable to SQL injection attacks (and ELMAH is in there to save the day if something goes wrong):
[Code]...
The problem is since I am using a like statement, I need to be able to have % on either side of the search word, and I can't seem to do that with '%:searchterm%', it just gives an error of ORA-01036: illegal variable name/number.Can I parameterize but still have my flexible like statement be a part of it?

I have converted a Windows Forms VS2003 application to VS2005 and then to VS2008. It includes a setup project for deploying on the client computer (the regular installer, not click once). It works fine when I run it on my computer, either in VS or if I install using the setup installer. But when I install it on the client computer and then try to run it, I immediately get a System.InvalidOperation exception. I put in debug code before my code but it fails before it gets to any of my code. Both computers are XP. The client comptuter actually has VS2003, though it is not used.
I have tried it with either the 2.0 framework or the 3.5 framework (and included those as prerequisities) but neither makes a difference (and I did set that in the Launch conditions, as well as in the Advanced Compile Options). The application uses CrytalReports for VS.
I don't think I can run JIT debugging on the user computer due to permission issues. Are there any other debugging things I can try to narrow this down or has anyone encountered this.

I can create a brand new empty console app in Visual Studio 2008 and add a reference to c:myfilesCrystalDecisions.Enterprise.Framework.dll and verything works just fine.If I do the same thing with the same file in Visual Studio 2010 (after changing my targeted framework to 3.5), I get the error that "CrystalDecisions.Enterprise.Framework.dll or one of its dependencies, requires a later version of the .NET Framework than the one specified in the project." In Visual Studio 2010 it won't work unless I change my targeted framework to 4.0. How is it possible that a DLL could be incompatible with version 3.5 of the framework in VS2010, but compatible in VS 2008?

I have Visual Studio 2010 and a VB Project that had a reference to Microsoft.Interop.Excel 12.0. Well recently I changed the reference version to 14.0. That was actually a mistake and now I need to bump it back down to version 12.0. However I get this error in my project now...
Project 'MyProject' requires a reference to version '14.0.0.0' of assembly 'Microsoft.Office.Interop.Excel', but references version '12.0.0.0'
of assembly 'Microsoft.Office.Interop.Excel'.
I tried removing references and adding the com object to, but no avail.

I have developed a windows based application using visual studio 2005 called DMS. On the client side, this application runs on asp dot net framework 2.0. We have created its setup file which has to be installed on the client pc. After the installation of the application, some of the users get the error message as:
DMS.exe - .net framework initiation error Unable to find a version of the runtime to run this application
(I have also attached the screen shot of the error message.)Trouble shooting done by me:
a. I had tried the re-install Dot Net Framework 2.0.
b. Scanned the PC for virus attack.
c. Install dot net framework 2.0 first and then the application.
But none of the solution works. The only thing that works temporarily is un-install the whole application and re-install it. Then it works for a few hours.

I am using VB.NET 2008 Express Edition and INNO Setup. When I create a setup and run it, the resulting install is an older version of my project from, I think, 2 or 3 days ago. If I go back to my project in the developer window and run the project, it is clearly a newer version than the install. Since this installed version that comes up was done I have added a form and made many other changes.Is it because the build didn't exeucte? When you run the project doesn't it execute a build every time?I tried this again from a backup. (The backup is much more recent than the version I'm getting.) And it still does the same thing.Why does the install not match the project? It is not possible to go into the project and add the changes because they are already there.

As some of you may know, I'm trying to develop a client/server application that requires sending files and text. Text is not a problem, this works fine, and for some of the part, sending files works, but they get slightly mangled in the process. For example, I used a 4x1 BMP that was alternately coloured red and white and tried sending it across. The output was the correct image dimensions, but the colours were wrong. It was more like a very dark red and very dark grey. I inspected the files with notepad, and the header was the same, but the data was different.
I did some research and apparently need to use a BinaryReader and BinaryWriter as opposed to reading the data as a string (like I was when it was being mangled) but now the data is all wrong, even filesize is different.The code below is a simple example of code for reading an image and then writing it again elsewhere using Binary Read/Write.
