Can't Seem To Get It To Recognize System.Data.OracleClient In VB 2010

Mar 28, 2011

I 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, 2010

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.

Exception:

System.Exception: Unexpected return code: 1 at System.Data.OracleClient.DBObjectPool.GetObject(Object owningObject, Boolean& isInTransaction) at System.Data.OracleClient.OracleConnectionPoolManager.GetPooledConnection(String encryptedConnectionString,

.net - Insert Large Blobs Into Oracle 10G Using System.Data.OracleClient?

Mar 26, 2010

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.

Constructing A Good Search Query Using System.data.oracleclient?

Sep 11, 2009

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?

System.Data.OracleClient Requires Oracle Client Software Version 8.1.7?

Jan 15, 2009

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?

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 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?

VS 2010 ManagementObjectSearcher Won't Recognize As A Class

Jun 7, 2011

VS won't recognize this as a class, I get the "Type 'ManagementObjectSearcher' is not defined." error. Usually when this happens I just need to import something, in this case it's System.Management, however this doesn't do anything. I'm quite new to programming so it's probably some very simple mistake or misunderstanding.

VS 2010 Recognize Time And Date In CSV File?

Mar 28, 2011

I'm building an application in which a certain CSV schedule is read and searched for time and date values.

I want to read each cell in the CSV file with a streamreader and have VB determine if the contents of the cell represent a date (like 31-10-2011), a time (like 22:30) or random text data which is not formatted like a date or time.

How can I make VB recognize a string as either a date, a time or neither one, so I can use this string formatted as Date, Time or discard of it?

The contents of the CSV file will look something like this:

;Schedulename;text;text;31-10-2011;text;text;6-11-2011;text;;;text

Although the CSV file will never contain much data, the position of the date and time fields in a row may vary, so I cannot tell VB which cell to read as date/time. It has to recognize the value as date, time, or unusable text.

Dim CSVReadline As New System.IO.StreamReader(schedule.csv")
Cellcheck = CSVReadline.ReadLine()
String = Cellcheck.Split(";")
For i = 0 to 10
Scheduledate = String(i) ............ etc.

Automatically Recognize And Handle Changes Of An Item In A "System.Collections.ObjectModel.Collection"

Feb 4, 2011

I wanted to create a custom control with a custom Item-Collection in it.(Similar to the ListView Items, but with other properties)I wrote a Class that holds properties of a single Item data (ClassItemData) and another class that "Inherits System.Collections.ObjectModel.Collection(Of ClassItemData)". The Collection class contains a public event (ItemCollectionChanged) which is raised when "ClearItems", "InsertItem", "RemoveItem" or "SetItem" is called. (I used "Overrides" on all these functions and added the Raise Event to them.) The event is handled in the custom control itself and causes the control to refresh/repaint itself. The collection class contains also "Default Public Overloads ReadOnly Property Item(ByVal index As Int32) As ClassItemData" which returns the Item at the speciefic index.

The control refreshes itself when I place the control on a form and use code like: ControlName.Items.Add("TestItem") Unfortunately the control does not refresh itself when I use: ControlName.Items.Item(0).Visible = False The value of the Item itself has changed after this, but the control does know about the changes and does not refresh itself. If I do a manual repaint/refresh of the control, it looks all fine, but it does not work automatically. Does anyone know, what I have to add, so I can handle an event or something in the control when a property in the ItemData class has changed? How do I recognize changes in existing items and raise an event in the custom event?
