I have an error to go mad. My vb.net application makes a report that runs fine in my local machine (with vs2003 and SQL Express 2005).

Then my app returns the error "Query engine error: "c:....".The actually data origin for report is a dataset, and I've compared the two datasets fill

I have a form showing a datagrid that is filled with info from an Access database table. The table only has 3 fields: two of them are string type and the third one is boolean. The first String type field is also the primary key (this field is called "clave"). This datagrid is supposed to let the user select one of the rows and then click on a button to delete that row. I'm trying to do that with the following code:

i am having an sql query in catch block. the code is: Dim str_exception As String = ex.Message Dim sql5 As String = "insert into table_data(type,description) values
('ERROR'," + str_exception + ")" Dim cmd_sql5 As New SqlCommand(sql5, connection)cmd_sql5.ExecuteScalar() it throws an exception at cmd_sql5.ExecuteScalar().
the exception is - incorrect syntax near 'records'. i tried adding single quotes like'incorrect syntax near 'records' .' .but still it is giving me the same error. I think it is because of the quotes near records. this exception is thrown somewhere else in the code and then it comes to cath block. i want to save the exception in the database.
I am developing a software that connects to a database and manipulates product and user data. It works on my computer but it will have to be used by many computers maybe even world wide (who will access the same database) so I have no idea what kind of systems people will have. I still don't know how to ensure that they will be able to connect to the database for I have already had problems in Windows 7 computers which don't have jet oledb.4.0
I am a bit lost here because I don't know if I should first try to do a connect, or if I should first look for a jet oledb engine on the computer where the software is installed. And in case they don't have it installed should I prompt them to install it before running the program further? Or should I pack the engine along with my program? What is the line of thought here to make the program run on (almost) any machine?
just if you are using Microsoft Access Data Connectivity Components 2010 in your application to read data from mdb access files, you might get unexpected exceptions and your application will crash!To reproduce this behavior the best way is to run my sample application which will allow you to see the bug directly in no time.This behavior may occur at any time, any where, but I found if you use Application.DoEvents, you increase the chance to run your application to crash.To reproduce ::
1. You should not have any Office version installed on your system (I am using Windows 7 x64).
2. install the Microsoft Access Database Engine 2010 x86 (or x64 and you'll have to set your project to x64).[URL]
3. Download and run my sample application in VB.NT 2010, and press the button, you will get it [URL]Where is Microsoft going, do you think?Should I hope to receive an official response?

I have a vb.net 2005 application that connects to an access database. I use Access Database Engine 2007 to connect to to this database.
Everything worked fine until i install MS Office 2010. After this, the application started to crash, returning the error 'application has stopped working'.
I've a Windows Seven Enterprise SP1 32bits.
When i debug the application, visual studio also crashes. I get the following error, closing an OleDbConnection: 'vshost.exe stopped working'.
I decided to run some tests. I installed my application on 2 virtual machines: a windows xp sp3 and a windows 7. When i installed ACE 2007 everything worked fine, but when i installed ACE 2010, thats when the problems began. This behavior ocurred on both machines.
It used to be that the VB6 installation tool automatically recognizes a MS Access dependency and includes the appropriate DLL(s). In VB.Net (2008) I am struggling with the concept of having to have two different installations, one for my tool and one for the 2007 MS Access Database Engine... Can you tell me if there is at least a way of manually including the appropriate Database Engine Files in my application installation?
