Paradox Conversion - Front End View
Feb 10, 2007
Hello All,
I know nothing.
I am helping a friend, current database Paradox 7.x, custom app as I am sure they all are. I wanted to convert this DB to SQL or Access(MS)I do not have Access, but I have SQL 2000. I used the import/ convert tools within SQL, looked good to me, no errors etc.
I thought life was good. Now try to view, look at the data the way
users could. In the SQL manager, I can see tables, and stored procs, and lotsa cool stuff. I try and install SQL client on a PC to view. It basically extends the Admin tools to the deskop PC. How do I use an SQL conversion to realize the needs of the user interface. I think I need what is called a front end. You can stop laughing now.....
Anyway what direction should I take
to update this antique, no support Paradox DB.
Thanks, Dan T

I have an application that uses Acces as a backend and VBA as front end. Application is secured and is supplied on a CD with setup.exe.
Can I use VB 2005 and MS SQL to achieve the same?
Would I be able to package my application with all the neccessery files (assuming that client does not have any e.g. SQL server) so that multiple front ends can access data from common source?
Would I be able to secure such an application using only VS 2005?
What would I need to quickly learn how to achieve the above ( any books you can suggest maybe)?

I have a view that is involved in an import. Sometimes the import will fail with the following error:
Msg 242, Level 16, State 3, Line 2
The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
I can recreate the error just from selecting from the view. Why would something be converting when just selecting from view?

hi all,
The PATINDEX function is not working with the image datatype in SQL Server.
The books online says that you can use PATINDEX with the image datatype.
Unfortunately it seems to be big lie.
How can I get the functionality of PATINDEX worked.
This is how I placed my SQL Query
declare @p binary(16)
select @p =0xFFFFF30A000000008400000001000000
select patindex('%DEFG%',image) from image where textptr(image) = @p
The error I am getting was
Server: Msg 288, Level 16, State 1, Line 4
The PATINDEX function operates on char, nchar, varchar, nvarchar, text, and
ntext data types only.
Why this is not working, according to Books online
Thanks for your time
bye

Hello,I've the following problem. I've to read out the data of a customapplication. I think (I'm not sure) this application is using aParadox DB to store it's information. I don't know it exactly causeI'm not familar with paradox at all, but I've found files like *.db,*.mb, *.px, *.xg*, *.yg* !!!I need the infomation from this files to combine it with other datastored in SQL 2000. I'm tried DTS to import the Data but I've got an"Microsoft JET Database" Error telling me that the table could not befound or that the table has not the asumed format. It depends on which*.db File i try to open. Description: Error calling the OPENROWSETmethod on the provider.My Questions, are there some special drivers i need, not included inMS MDAC Components or must I use a complete Databaseserver in theBackgroud hosting the DB Files. My developer station has the customapplication NOT installed. The db files seems to have no password set.I've got the same error when using MS Access to import the data. Ionly set the path to the dictionary where the files are in but leaveusername and password blank.HOW TO GET THIS DATA OUT ???Thank youTony

I am updating a Sql Server 7.0 DB to Sql Server 2005 Standard
I have to update Sql Server tables with Paradox 4.5 (DOS) data,
with DTS in 7.0 this was no problem.
In Visual Studio I use the OLE DB Jet 4.0 driver with the extended property "Paradox 4.x"
The package runs well if there is no Memofield or the Memofield has only a few characters.
If there is an Memofield filled with more than 250 Characters the preview and the data flow faults.
If I use "DBASE IV" on a dBase-table there is no error, but the NTEXT-Field in Sql Server has only one character " "
What can I do to get Paradox-data with Memofields?
Other problem:
I am missing the OLE DB Jet 4.0 Data Source in the Import/Export-wizard in
Sql Server Management Studio.

I have a Paradox file which has 270 thousand records. If I open this db file through a paradox viewer it shows the correct number of rows.
I have an SSIS package which is suppose to read this db file and insert it into the SQL 2005 table. But when I execute this package it goes into a loop, reading the file over and over again. The package fails after inserting some 10 million rows giving the error msg 'Not enough space on temporary disk'.
On examing the data transfered into SQL there are duplicate rows.
I also used the import export wizard (thinking there might be some error in Package code) provided by SQL to transfer the data from .db to SQL but it has the same result(goes in a loop).
I would appreciate any help in this problem. Let me know if you have any other questions.
Thanks

We used to use DTS to read Paradox files. This is something we do regularly. DTS has a native Paradox driver. This seems to have disappeared in SSIS.
Can anyone recommend the best way to read Paradox Files with SSIS?

Hi,
I have been told, I will have to transfer some paradox data into sql server 2005.
What is the best way to do this? i.e. if SSIS can be used, then what will be the source? I ask because there does not seem to be a source for Paradox.
Any thoughts please?
Thanks

I've been programming in Paradox since DOS, but one mail-order database is getting rather large (100K client records, and associated orders, etc).
Our client wants us to move to Filemaker. In fact he'd like to have a 3rd party write the programme and me maintain it. The current package has been written & maintained by myself, with an awful lot lot going on in the Object PAL code.
I already have a copy (legal) of SQL Server & 10 licences for Access, and think that's a better option to re-develop in (although I could do with some training in both).
What are the pros & cons for each app, and what would people recommend. I'm going to cross-post into Access, Paradox & Filemaker forums to get an equal view.
Thanks

Hi,
I'm trying to import a Paradox 8 db into SQL Server 2000 using DTS but the list of data sources in the connections dialog only caters for version 5.x or older. Does anybody know how to get the data source for v8?
If not, is there any other quick and efficient way to import a paradox 8 db as I have to import around 15 of them to do.
Thanks

I've never really setup or used MS SQL Server (just a couple hours, oneday, several months ago). I think MS SQL Server has the ability to use"linked tables", like MS Access does. Is this correct? What I want todo is have an MS SQL Server setup, which compatible applications cantalk with, but I want the data to come from a Paradox database. I canuse any MS SQL version, whatever would work best. I'm not sure aboutthe Paradox version, I know it is an old DOS version. I can't justconvert the data to another format, because Paradox still needs to useit.I tried using MS Access before, with ODBC drivers it *should* be ableto work with the Paradox data. However, I ended up with lots of datacorruption. I'm hoping MS SQL Server may work better, and not corruptthe Paradox data everytime it is updated.

Hello,
I have SQL Server 2000 and I'm trying to import data from a paradox v5 database. Everything has moved over fine but the data from the blob fields. When I use the import tool and try connect to a paradox blob field, the import wizard does not "see" the paradox blob field. here is and example.
If I have a table with the following fields.
id char(20)
description char(120)
image blob
the ms-sql import wizard sees
id char(20)
description char(20)
I find this very odd, but I do need a solution. Any Ideas?
TY

The problem that when i start debugging an error raise as the following:
Error: 0xC0202009 at Data Flow Task 1, OLE DB Destination [554]: An OLE DB error has occurred. Error code: 0x80040E09.
Error: 0xC0047022 at Data Flow Task 1, DTS.Pipeline: The ProcessInput method on component "OLE DB Destination" (554) failed with error code 0xC0202009. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
Error: 0xC0047021 at Data Flow Task 1, DTS.Pipeline: Thread "WorkThread0" has exited with error code 0xC0202009.

Sorry for the lengthy question, but here goes:
I currently have an access database with a FE and BE that resides on each users laptop. Weekly they connect to the network and synch the BE the master on a network drive. There are numerous propblems with this as it has grown quite extensive.
We would like to have this be a server based database with the remote users either having access through the web or something else?
A few of the capabilities of the current database:
1. generate and print reports 2. update project forms. 3. enter time logs 4. enter notes
My question is:
What are my options for a remote FE? I am well versed in VB6 and Access. Would be willing to learn other languages (VB.net, my SQL, etc.) Would I be able to have the same functionality or would I have to have separate software for certain functions?

Hi,
If I don't have any visual studio design tools etc.
Is there any way I can build a simple form that will allow users to view, insert, update and delete single rows from a SQL 2005 database?
Or is there any free downloads that might help. the table is really simple and has only 4 fields
TIA

I'm doing a database for employee info and thier payroll.. im using SQL Serevr 2000 and IIS but i'm not too sure what to use as the frontend, a VB would kinda be overkill because each employee just needs to be able to update his own info and addresses, maybe a XML or some other page that uses windows logins for authentication? any ideas, this is my first project like this on on a college Coop

i am almost finished building the front end for an application to manage restaurants. i am developing the front end with access vba, and intend to use sql server as a back end for the service. i just came across a group of people bashing access developers on a different site. i have several restaurants interested in using the service, and believe that the service should be very successfull (i have a very specific customer base that is currently not being targeted). the access component would not be a multiuser application. before i distribute the app i would appreciate any input. am i getting myself into trouble using access vba? should i run scared and switch to a vb.net web service?
thanks in advance for any thoughts.

Below is a post by blindman from my other "mentoring" thread (http://www.dbforums.com/showthread.php?t=1608569). I wanted to respond to it but not in that thread:
Yeah, but if he's going to go unbound he might as well develop in .Net rather than Access. You lose half the convenience of MSAccess as a front end if you use unbound forms and controls.
Besides, he's trying to learn SQL Server, not front-end development. Learning both at the same time may be a bit much. I'd suggest he stick with his idea of converting the Access database to SQL Server back-end.
But, you should definitely convert the Access front-end to a Microsoft Access Data Project, rather than a classic mdb file.
Going unbound would increase your application performance, but probably not noticably unless you have scores of uses, and since you are currently using straight MS Access I'd guess you have no more than five or six simultaneous users, right?
blindman
To start I have decided that ADO is the way to go even though I don't necessarily need the performance boost for my current situation. Keep in mind I am planning for future and more demanding opportunities, hopefully :) And I'd like to learn the "right" way to do things.
I actually use ADO quite a bit in my current DB app and bound controls as well so it really wasn't a new concept. However using strictly ADO produces alot more work and code. And like blindman says it pretty much takes all the ease of Access away and VB.NET for that matter too. I mean all the wizards are useless. So I have two questions:
1. When going to all ADO you are pretty much recreating what Access already does for you right? Coding in ADO is more work right? I mean you have to setup connections and fill fields and listboxes manually in code right? I don't mind the extra work I just want to make sure if I'm going to be doing all this extra coding that it is the right thing to be doing.
2. MDB vs. ADP - From what little I've read Access Data Projects are made for use with SQL Server. It is even more useful if you don't/can't actually work in SQL Server. But again if I'm using ADO it strips all the usefulness of the ADP's doesn't? I don't need ADP's to create views or sprocs. I can do all of that through the management studio. So does it really matter if I use an ADP or MDB as my front end if that is all it is going to be is a front end?
Lastly I wanted to use VB 2005 as the front end but we utilize a ton of reports. As far as I know Crystal Reports or something like it has to be used with VB 2005. Or does VB 2005 have some built in reporting capabilities? I thought I saw some report designer for VB6. Anyway I decided to stick with Access because I am familiar with its reporting capabilities.
I should note that I have VB 2005 Express and SQL Server Express. Right now my company is not putting any money into a higher version.
Let me know what you all think.
Thanks,
GG

Hi!I'm trying to build an app. for my parents' office. They have a smalloffice (5 PCs), and they currently work with a very old program that'sbased on DOS. The program doesn't work well under XP, so they still useWin 98. They had their network upgraded about a year ago. They hadMicrosoft SBS 2000 installed, it includes SQL Server. I've written afew DB's in Access before, and now I'm just learning how to use SQL.Before I start work on their app., I have a question:I know it's possible to create an interface that can be put on theirnetwork and accessed via a browser. How is this done exactly?It would be very beneficial for me, because it would mean that the newapp. would be platform independent, so that they can upgrade to XPeasily. It would also save us the cost of licensing front-end software(e.g. Access) for each machine.Any comments would be appreciated.Noam Nelke, Israel.
