Error Unrecognized Database Format 'C:Program FilesMahrsoftRafiq And CompanyDatabasemaindb.mdb'
Jul 17, 2009I am using windows vista and visual studio 2008 pro. I am facing a strange error. In the main form of my application i am opening a connection to a database using OLEDB 2.7 like:
conStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:Program FilesMahrsoftRafiq and CompanyDatabasemaindb.mdb;Jet OLEDB:Database Password=*****"
con.ConnectionString = conStr
con.CursorLocation = ADODB.CursorLocationEnum.adUseClient
con.Open()
But it give an error on the last line like:
Unrecognized database format 'C:Program FilesMahrsoftRafiq and CompanyDatabasemaindb.mdb'.
I can open the database using ms access 2007 and it is showing every table and i can open the tables and view data but what is the problem with connection?

DB/Reporting :: Unrecognized Database Format?
Jun 3, 2008Alright, so I am getting the error "Unrecognized database format 'location'" on a project I have been working on for a while now.First off here, I am working in VBE2008, SP 3, fully updated Jet drivers, I have repaired/updated the database, and I have made an Access 2000 and 2003 version to test.Best part is, is I am working with 2 databases, one to be carried with the program, one to be outside. When I was first working on the code, the database that is "unrecognizable" now was working fine until I had to change my format to carry it with the program.So I am assuming either my code is wrong, or some divine force has stricken my databases for something I did.
Code:
Dim conn As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OleDb.4.0;Data Source=C:StryperPrice.MDB")

Web Service On Server Error Request Format Is Unrecognized For URL?
May 9, 2009Request format is unrecognized for URL unexpectedly ending Error I have 3 webservices on windows 2003 server. All worked fine before and are called from one .net application on another server. Recently I added a few new webservice calls, builded and published . All webservices works fine on development locally. On production server all stopped working.
I would like to know how to solve the problem and how to capture the failure of webservice call. The application that is calling those webservices starts new thread to process and shows user Thanks you will get an email. However webservices stopped working and it took couple days to learn that nothing is happening, after research I learned that webservices do not work anymore. Bummer, I do not know how to alert in this case.But first more important how to fix it. On development server in VS 2005 all webservices works perfect. After publishing and testing on server to Invoke a service, the Error ....unexpectedly ending.. appears. After reading many happy postings that modifying Web.config node protocols, I discovered that instead of

Convert A GUID-like String To A Different Format?
Jan 12, 2010Here's the basic premise though: I need to convert a GUID-like string to a different format as shown in these examples:
Original String:
{291B3A3B-F808-45B8-8113-DF232FCB6C82}
Converted String
B3A3B192808F8B541831FD32F2BCC628
[Code].....
It works, but it doesnt seem very well written... Oh and if you are wondering why I wrote my own ReverseString method rather than just using the Reverse extension method on the String class - It seems to return a collection of chars rather than a string (god knows why) and I couldnt find any easy/obvious way to convert this collection of chars back to a string (I thought just CStr would do it but apparently not)
GUID Format - Generating 6 Random Alphanumeric Characters
Feb 25, 2011I'm trying to use a GUID to generate 6 random alphanumeric characters (just letters and number). Is there a way to change the format of a GUID before it is generated. Or must I generate the GUID in its standard format and then manipulate it.
View 5 RepliesAdd An SQL Database File Using VS 2005 Getting Error Message Saying Version Of Database Server Not Supported?
May 18, 2009I recently upgraded the MS SQL Server installed on my personal computer from 2005 Express to 2008 Express. Problem is when I try to add an SQL database file to a project using VS 2005 I get an error message saying that the version of my database server is not supported, I must have SQL Server 2005 Beta 2 or later installed. I didn't do it yet but I'm pretty sure that when I open the other projects that I included a database file to it, I'm going to get the same error.
My question is it possible to have two SQL Servers installed on my machine? If so, is it a good idea to have two DB servers in the same machine?
DB/Reporting :: Database Unrecognized Field, Can't Insert Data
Apr 19, 2009I've been staring at this and can't seem to come up with a solution. I've tried several different methods that i found on the web but to no avail. I'm hoping you all could take a look at the code below and give me some direction as to why I'm receiving the error "The INSERT INTO statement contains the following unknown field name: 'Deposit_Date' . Make sure you have typed the name correctly and try the operation again. Sorry if it's kinda jumbled below
Code:
Dim SQL As String = "INSERT INTO Deposits ( Deposit_Date, Deposit_Time, Location, Miscellaneous, " & _
"Miscellaneous_Adjustment, Dispense, Dispense_Adjustment, " & _
"Replacement_Card, Replacement_Card_Adjustment, Deposit, " & _

No Connection With Database (possible No Internet Available) / It Should Display An Error Message
Aug 1, 2010I've added a database to my application with 2 fields:"ip" address and "started" that holds the number the application was started from that specific IP.I want to upload the database to my site hosted at google.sites. When the program is started it should make a connection with the following cases:
1-no connection with the database (possible no internet available) - it should display an error message
2-there is connection, the IP is not stored on the database, it addes the IP to the database and the field "started" with the value 1
3-there is connection, the IP is stored on the database, it increments the field "started" by 1

C# - Nullable(of Guid) With Generic Delegate Causes Weird (hidden) Error?
Jun 6, 2011Scroll to the bottom, EDIT 19 onwards. See @Chris's comments also for good examples
[code]...
It's all gone quiet since Edit 19ish and @Chris reinforcing the issue with a good example (thank you Chris). I'll make the question a little easier (and attempt to tidy up all of the above), can anyone prove this is not an MS bug or similar? It seems to be something under the hood is not correctly wired up for VB.Net with regards to Nullable Structures and Events? However, all other cases using the Nullable Structures does appear to work?

Invalid Path To Database Error Message After Deploying Project Created In Program2010
Jul 6, 2011Is there any literature which guides a user through the steps of deploying a vb project created with VS 2010 Professional and incorporating SQL 2008RE Database?

However, after adding the databases in the project as existing items and deploying, the project opens/runs, but when I try to login the application I keep getting an error message telling me that the path to the .mdb (Access) database is not a valid path. I don't have a clue what else to do.

I get an error on Guid.Empty "Constant expression is required."
What I'm trying to accomplish is to get rid of this line that shows up in the Designer file,
Me.TestUserControl1.KeyValue = New System.Guid("00000000-0000-0000-0000-000000000000")
I can avoid running the property's Set code with some conditionals on the Value sent when the form instances. I was just wondering if there's a way to deal with it similar to other data types.
