Can't Seem To Get It To Recognize System.Data.OracleClient In VB 2010
Mar 28, 2011I can't seem to get it to recognize System.Data.OracleClient. I downloaded and installed the 11gR2, added a reference to Oracle.DataAccess. Looks like there is a 4.112.1.2 and a 2.112.1.2 versions. I'm tried adding both to the project, but neither are giving me access to that assembly. i.e.

System.Exception: Unexpected Return Code: 1 At System.Data.OracleClient.DBObjectPool.GetObject Error
Jul 13, 2010I 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.

.net - Insert Large Blobs Into Oracle 10G Using System.Data.OracleClient?
Mar 26, 2010Trying 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.
View 1 RepliesConstructing A Good Search Query Using System.data.oracleclient?
Sep 11, 2009I 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?
System.Data.OracleClient Requires Oracle Client Software Version 8.1.7?
Jan 15, 2009I 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?
System.Data.OracleClient Requires Oracle Client Software Version 8.1.7 Or Greater?
Oct 12, 2009I am using VS 2008 with frame work 2.0. On my development machine I am using Oracle 9 as database. When I deploy my application where Oracle 9 is installed it works properly. but it gives error on oracle8 NT installed machine as follow.

Deployment :: System.Data.OracleClient Requires Oracle Client Software Version 8.1.7 Or Greater
Apr 10, 2009i 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?
System Cannot Find Reference Specified
Dec 7, 2011In my project i had an added reference which has always worked,, today and out of the blue i start getting this error
View 1 RepliesSystem Cannot Find The Reference Specified?
Apr 22, 2010I have a Windows Forms application built in VS2005 and migrated to VS2008. I copied this application from one development computer to another, and now it states <the system cannot find the reference specified> for every single reference. These references are basic things like System, System.Data, System.Windows.Forms, etc. I cannot even look at the forms since it cannot find the reference to the DLL.
The computer the application was copied to has VS2008 installed and I can find the references in the appropriate location of (C:WindowsMicrosoft.NETFrameworkv2.0.50727) and also in the GAC (C:Windowsassembly)
However, even if I try to remove the references and add them back in again it still says it cannot find the specified references.
VB 2008 : The System Cannot Find The Reference Specified
Sep 19, 2011I've created a class library in Visual Studio 2008, and when I try to add the dll as a reference, I get the message in the title for the Path field in my project references. I've been going for a week trying to figure out this issue, and I haven't been able to come up with anything. The strange thing is I can add the same reference to a Visual Studio 2010 project, and it works perfectly fine.I used VS 2008 to build it because the dll isn't used in house and needs to be compatible with .Net 3.5.

VB 2010 - System Cannot Find File Specified
Dec 30, 2011I'm trying to make a toolkit of all the software that I use to do virus removals, PC Tune-Ups etc.. The issue that I am having is I cannot get the program to execute. For Example: I have created a small program with several buttons on it that I would like to execute specific programs that I have when they are Clicked. If I Click the 'Combofix' button, I would like 'Combofix' to start.
On my computer all the button functions work properly they execute the program that i have coded them to execute just fine on MY COMPUTER. However, when I publish the program and migrate all the publication to another computer the buttons do not work properly. My first thought is that I do not have them directed properly. As if the program does not have the other software (combofix) being copied with it.
This is the Error that I get - 'The system cannot find the file specified.'
This is the directory that i am using - Private
Connect To Access Db File From VS2020 (can't Find System.Data.OleDb)?
Dec 9, 2010I have been programming vba for some time and am now starting VB.NET. I need to connect to an existing access db file (access 2003). I downloaded VS2010 and found an example on the net. Here is most of the code:
Imports System.Data.OleDb
Public Class Form1 Inherits System.Windows.Forms.Form
Dim cn As OleDbConnection
Dim cmd As OleDbCommand
get the argument for the desktop of the user
I am getting this error message:
1 End of Statement Expected
I have tried to add a reference to System.Data.OleDb but it doesn't appear in the add reference box. System.Data.OleDb is checked in the Imported namespaces window. I have tried changing the .NET Framework but, no help.
VS 2010 - System.UnauthorizedAccessException - Find A File On Computer And Return Path
Jun 12, 2010I'm running windows 7 64 bit and using VS 2010. I'm trying to use the filesystem.getfiles to find a file on the computer and return the path for it. However, when I search C:/ and its subdirectories, it always throws an error: "A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll"
I've looked everyone online and can't find a solution. I have administrator privileges and really I dont want people who use my app to have to adjust security settings for this to work. Is there not a way to search the C drive for a specific file and return its path? [Code]
VS 2010 SQL.Data Reference Not Working?

Shouldn't that reference dll follow with the program in the programs exe or something?
VB 2010 - Rank The Data - Divide The Data - Find The Median
Oct 14, 2010There are few steps to find out the half slopes of the graph.
Step 1: Rank the data The independent variable is required to rank it from the lowest to the highest.
Step 2: Divide the data Divide the sample size into 3 roughly equal parts, which is the lowest, middle and the highest parts. If n/3 has remainder of 1, +1 into the middle part. If n/3 has remainder of 2, +1 into the lower part.
Step 3: Find the median The size of each part = n, find the ((n+1)/2)^th value for both dependent and independent variables. If the ((n+1)/2)^th is not an integer, sum up the 〖n/2〗^th value and ((n+2)/2)^th value and divide the total by 2 to make it as median. The median, m1 for independent variable in lower part indicate as XL , middle part median, m2 as XM and the highest part median m3 as XH. For the dependent variable the median is indicate as YL, middle part as YM and the highest part as YH . Figure 3.2 Example of median m1, m2 and m3
Step 4: Find the half slope Find the half slope for the lower half, b_L=(Y_M-Y_L)/(X_M-X_L ) and for the upper half, b_H=(Y_H-Y_M)/(X_H-X_M ) .
Step 5: Find the half slope ratio, b_0=b_L/b_H . If the ratio is negative, the dependent variable need to add with a constant, c in order to make the slope same direction.
Step 6: Identify transformation. Depend on the graph pattern pick one type of transformation which is nearest to the original of the variable.
Step 7: New half slope Find out the new half slope ratio, b1 by repeat step 4 and 5 with the transformed variable.
Step 8: Repeats steps Repeat step 6 and 7 with choose the transformation which is nearest to previous transformation and find the new half slope ratio, b2, b3,�, bn. Repeating this step until |1-b_i |≤|1-b_j |, for i<j, i and j = 1,2,3,
Step 9: Result bi is chosen. The data transformation used in bi is the most closest to be normality.
