I am reading a csv file in to a datatable in vb.net and making a few checks and appending an extra column. I then want to perform a bulk insert using microsofts Oracle.DataAccess (no choice in this) to an Oracle database. what would be the best way to perform this as there is no bulkImport like in SQLserver.
View 2 Repliesi am trying to redistribute my app that uses Oracle 11g:
Imports Oracle.DataAccess.Client
The problem i am having is that it will not run on a machine that doesnt seem to have the correct drivers that its looking for. When i install ODAC 11.2 Release 3 (11.2.0.2.1) with Oracle Developer Tools for Visual Studio on the test VM it works just fine but thats a 230+mb file to download and install! Not to mention that if the user already has Oracle 10/11g on their machine that it may mess up their current connections/etc by installing that setup file.Is there another setup package that i can install that only has the Oracle Data Provider for .NET 2.0 11.2.0.2.0 or whatever its needing from that ODAC 11.2 Release 3 file.
Trying to insert a large audio file into an Oracle 10g database and keep getting this error:
ORA-01460: unimplemented or unreasonable conversion requested
The byte array length of the audio file is 2702577. The procedure works with smaller array lengths, but not the larger ones.
Here is my code:
Dim oracleConnection As New OracleClient.OracleConnection
Dim Cmd As New OracleClient.OracleCommand
Dim oracleDataAdapter As New OracleDataAdapter
oracleConnection.ConnectionString = System.Configuration.ConfigurationManager.AppSettings("MasterConnectionODT")

View 2 RepliesOk 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.
Relatively new to VB.NET coding. Am creating a pretty simple console application that needs to insert over 50,000 records into an Oracle table (OleDB connection). I tried 3 different methods so far: Individual INSERT, insert using a dataset, & using INSERT ALL (commit every 25 records due to # of columns). It seemed like most articles/posts I read recommended the dataset approach, but the INSERT ALL code was definitely the fastest by far.

View 2 RepliesI am trying to insert date and time in dtime column in oracle database by using this code but it gives me following error ORA-01830 date formate pictures ends before converting entire output.
[Code]...
In my code I have an Oracle command that contains an INSERT statement. Here's a snippet from my SQL:
"'," & "To_Date('" & Format$(dtDateTime_Stamp, "MM/dd/yyyy hh:mm") & _
The value of strDateTime_Stamp is #1/19/2011 9:42:22 AM# I'm getting an error ( "ORA-01830: date format picture ends before converting entire input string") because I don't know how to correctly assign the AM/PM tag on the end -- you'll notice it just says "MM/dd/yyyy hh:mm" in my code. I've tried a bunch of different things but nothing works. I also find it odd that if I change the "MM/dd/yyyy hh:mm" to "mm/dd/yyyy hh:mm" (little m for month) it gives me a 42 for the month value, not a 1. The capital M's fix that but I'm curious to know why.how to I get it to show the AMPM on the end?
I have an issue that I can't seem to tackle. Going on 3 weeks. I have a VB.NET app with an sqlce 3.5 database. I have created several tables in this database. I have attached them to my form using DataSet then BindingSets and so forth. Done this many time before. VS automatically created a TableAdapterManager for me.I was having an issue getting the Refresh of the primary key value of a newly inserted row. Ok, find out that sqlce does not do big transaction, or multiples rows at a time, found Beth Massi's blog on how to work around this:Ok, got it somewhat to work, but I had to take one of the tables out of the tableadaptermanager so I can update it by itself so insted of doing this:
frmMain.Validate()
frmMain.bsRunInformation.EndEdit()
frmMain.TableAdapterManager1.UpdateAll(frmMain.DS1)

View 1 RepliesI have the following insert into statement. What I want to do is insert the values to gprdsql.TblOracleNos if TxtOracleNo is not empty, therefore if a user logs on and fill the textbox the values are saved to the table. However, if the oracle number exists in gprdsql.TblOracleNos (i.e, the values ) it should not insert the values, presently it creates the same record again with same values (when the save button is clicked) and this creates duplication. Instead probably bring a pop up message "Oracle number already exists. [Code]
View 6 RepliesTrying 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 a vb.net project that has 2 exe's that get built as well as the installer. The two exe's share a bunch of common files. I do not want to have two copies of the common files or mess around with having build events that copy things around (if possible).My method was to create two projects in the same folder and have them point to the files they needed.This appeared to work until I tried to compile both apps at which point I get an error in a file called Application.Designer.vb. It seems that project files create this file in their folder and when I have two solutions in the same folder they conflict.

View 4 RepliesI have an ASP.NET application (vb.net codebehind) that has serious performance problems because of its storage of TIFF files in one server share. There are over a million .TIF files there now! The application tracks the scanned images of property with a corresponding row in an Oracle database table. We have this idea that it might be better to store the images themselves in a new Oracle table.
The alternative solution we are thinking of is to split up the server share into multiple folders by State (an OH folder, a WV folder, a VA folder, etc.) Seems like the database option might make more sense long-term, but how do we do it? Can a TIFF be stored in a BLOB column and then extracted back into TIFF format using .NET?
I've written a loading program that writes text files to our database. The text files are dumped by another system every 2 hours onto on a shared network drive at my work. Here's the problem though - the files don't have a date/time stamp within them. I've been getting the date for each file from the creation date. That works okay, but when I've written loading programs in the past, I like to move the loaded files into a folder called "Loaded Files". That way, I can quickly see visually how many files I've loaded vs how many have not be loaded.
The problem this time, is that if I were to move the file into another folder, the creation date changes...a lesson I learned when I copied all of the files into a directory on my C: for testing. They all had the same date/time stamp!My question is, what's the best way to handle this? I don't want to move the files after loading them if it alters their creation date. I mean, what if I have to go back and load one for some reason, the date will be lost forever. I also don't want to write something into the software that has to check a file each time before loading it to the database.

I have a directory full of .txt comma delimited files arranged as shown below. What I want to do is to import each of these into a SQL or SQLite database, appending each one below the last. (1 table)... I am open to C# or VB scripting and just not sure how to accomplish this. I want to only extract and import the data starting BELOW the 'Feat. Type,Feat. Name, etc' line.
These are stored in a mynetworkdirectorystats folder on my network drive. Ideally I will be able to add functionality that will make the software/script know not to re-add the file to the database once it has already done so as well.
