i have to start out saying that I have never used VFP before, so this is all new to me. However, I am running into issues that seems to have nothing to do with logic or reason. Let me explain.
[Code]...
So, I have successfully loaded dbf's into my VB project.What I need to know now is how exactly do I utilize the VFP language in addition to SQL?
Say I wanted to replace all fields (REPLACE ALL field1 WITH field2) with another field, how would I send that instruction to the DBF utilizing the VFPOLEDB.dll?
I think what I have here is an environmental issue. When I attempt to fill a dataset from a VFP table I am getting an error message that says "Index Not Found". The reason I feel its environmental is because the process was working perfectly fine last week. The client I am trying to run this program for runs it once per month to integrate one of their FoxPro systems with SQL. It's been in working order since November of last year, but suddenly now I'm getting this error. Some things I have looked at already are updating VFP drivers for both OleDB and ODBC.

I am creating a VB.NET application that will use a FoxPro database as it's main datasource.The problem I've got is that I can browse existing databases and pull out data with no problems at all but as soon as I try and create my own database I get an error message saying "One or more errors occurred during processing of command." (which is helpfully vague).[code]

View 2 RepliesI wanted to write a small piece of vb code to synchronize a few FoxPro dbf tables to SQL tables that having the same structure or at least a few fields that i selected. I had tried a code which I found on the net that running row by row and column by column to update the SQL tables but this code is too slow. In my dbf table it contains around 3000 records at least.
View 12 RepliesI dusted off VB.net, and now im trying to connect to a local FoxPro DB. Problem is, its not working. Ive been at this for about an hour or so, trying many misc things, but without any luck. [Code]. 'C:aaaCF21000.DBF' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides. Suggestions? That path is 100% valid, I can copy/paste that and open up the Database without error. I also tried other code I found on the web, some of them I cant even get them to run.

I have a foxpro table <b> INVENT.DBF</b> linked in MS ACCESS. When I tried to do a search in the table from vb.net application, it is taking a long time. So I want to index the foxpro table and then use it for search.
Here is the sample code I wrote in vb.net <i>
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:database.mdb;Persist Security Info=False")
cn.open()
cmd = New OleDbCommand("Create INDEX itmno_idx ON INVENT(ITEM_NO) ", cn)
cmd.ExecuteNonQuery()</i>
But I am getting error "Cannot execute data definition statements on linked data sources"
What needs to be done to index a linked foxpro table using VB.NET.
As part of a larger application, I need to IMPORT (not link) a FoxPro 2.6 DBF into a Access DB.I toyed with using a Access MODULE and in the module, using the docmd.TransferDatabase method.I have looked for days at different samples and I cannot seem to find the answer.This application is intended to be distributed with NO ASSURANCE the user will have the FoxPro OLE driver installed. Knowing that the ODBC driver will most likely be installed as part of MDAC, it is pretty safe to use the ODBC driver that is already installed - Visual FoxPro Tables
View 1 RepliesI am new to VB and trying to use it to update and merge some foxpro free tables. I have a connection and trying to use the update command but getting an exception. Once the code hits the ExecuteNonQuery line it throws the exception {"Command contains unrecognized phrase/keyword."} Do I need to create the command using parameters? Just not sure. Is the connection string correct - I did not get any issue with the cn.Open

VS 2010, VB.NET, WINFORMS. In my app i have a need to import foxpro database tables and exclude the deleted records. The problem is that FOXPRO tables keep deleted items inside the same table. I have tried using DELETED=NO in the connection string but vb throws "Format of the initialization string does not conform to the OLE DB specification."
My function is as follows:
Dim _DBConn1 As String = "provider=vfpoledb.1; Data Source = " & file1 & ";DELETED=NO"
Dim _DBConn2 As String = "provider=vfpoledb.1; Data Source = " & file2 & ";DELETED=NO"
Dim _DBConn3 As String = "provider=vfpoledb.1; Data Source = " & file3 & ";DELETED=NO"
Google results pointed me in the direction of DELETED=NO but its throwing that exception error now that I have added it..

View 9 RepliesDoes anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?
How do I disable the background compiler for Visual Basic in Visual Studio 2008?

I am just wondering how I can add Direct X references to Visual Basic in Visual Studio 2010 Beta 2. I cant find them in the .NET reference list, or the reference list, or anywhere. I downloaded the Direct X SDK for August 2009, but I can not add the .dll files to the reference list. Is there anything I can do to add them? I need the references for programming reasons.

I have Visual Studio 2008 Professional and I'm trying to make it so I can click a button to send the application to the System Tray and then click the icon in the System Tray to make the application come back.
Can anyone provide me a method or sample code to do this?
when the user clicks on the add button another form launches, which enables the user to add student info such as name, address, course, start date and end date, this information is then written to class when the ok button on that form is clicked, and then displays the data on the initial form in data grid. the user can add multiple entries and they are all displayed on the intial form and a the data grid is populatedwhen any of the rows in the displayed grid is selected, and the update button is clicked then the same form launches as the previous one and but this time its in the update mode and pre populates the form with the inital values.
