hi

could an expert help me set this up in access 2000

do you want to run this code with access or vb.

if it using vb then the following will do.,

you have to add reference of microsoft access object in your vb project if you want to work. i have attached your sample code itself. further why do you go for api, when you have commondialog. i have attached the code for that also in the same project (in form2).


Furthermore how i can refrence the loade .mdb file when ever i want to use it instead of current db in vba

for loading the mdb you dynamically use the provider with the mdb filename which you have selected..

i hope it will help you.

[tony007]

Thank u for u helpfull post. Well i am using access 2000. Could u tell me how to import these files to my project? Furthermore, could u show me how to use the loaded mdb file rather then current db.Thanks

[kishore.kr]

hi

attached the example in the same project itself. just after selecting the database, open the connection to the new database.

[kishore.kr]

hi again,
are you using commondialog or api(just wanted to know) ??. given example for commondialog. if you are using the api the place the con.open statement in the appropriate place of the api openfile fn.

Thank u for u reply. I want create a form in access 2000 and put a button and once i click on that button i want be able to browse for mdb file . In the same page i am trying to load all table names in lis box but tables from dynamically loaded db not current db. But i do not how to that part alo.Thanks

[kishore.kr]

hi buddy,

finally i got it(hope so). actually previously i was posting based on vb application. sorry for that.

i have added a form in access. it has a command button and combobox.
in the build event of the command button(using code builder), i have added code of the click event of the button. plus i have added the module which you had posted on the first post. it is working fine in my pc. you select any database the items will be added in the combo list. make modifications as you need.

[tony007]

Many thanks kishor for your help.Now the form loades the mdb file.However I want to do many things in this form after laoding external mdb file. For example i want to run the following code on click of a new button from the same form :



Private Sub Command0_Click()
CreateSystemCatalog
End Sub

Sub CreateSystemCatalog()
Dim metadb As Database, db As Database
Dim metadbname As String
Set db = CurrentDb()
metadbname = Left(db.Name, Len(db.Name) - 4) + "_meta.mdb"
Set metadb = DBEngine.Workspaces(0).CreateDatabase(metadbname, dbLangGeneral)
MsgBox (" System Catalgoe tables created succesfully! ")

Call CreateSystemCatalogTables(metadb)
Call InsertSystemCatalogPopulation(db, metadb)
End Sub


As u can see the above code is currently refrencing current db how i can make it to refrence the dynamically loaded one? I need to learn this since i got many codes as above that i want to apply it to loaded external mdb file. i be happy if u show me how to do it.Thanks

[kishore.kr]

hi,
try using
set db = opendatabase("databasefullpath with filename")
hope it works. i am not comfortable with dao. so only i send you the ado code. did you checked the code.

Many thanks for u reply . Well yes i run your browse code . It run very well.

since i want to add another button to it to create system catalog for the current browsed file the "databasefullpath with filename " is changing each time i select a new mdb ! How to to put that automatically?(what i mean instead of Set db = CurrentDb() i want it rerfrences the browsed mdb).I want to acomplish this using eithr ado, dao.Thanks

i am not getting exactly what you want. can you put it more clearly. do you want a same method to open initially(first time) using currentdb and next(after opening new database) time with opendatabase().(is that you want).

Thanks for u reply. Well if i run the following code alone it will refrence the tables in current access db because of

"Set db = CurrentDb() "



Private Sub Command1_Click()
CreateSystemCatalog
End Sub

Sub CreateSystemCatalog()
Dim metadb As Database, db As Database
Dim metadbname As String
Set db = CurrentDb()
metadbname = Left(db.Name, Len(db.Name) - 4) + "_meta.mdb"
Set metadb = DBEngine.Workspaces(0).CreateDatabase(metadbname, dbLangGeneral)
MsgBox (" System Catalgoe tables created succesfully! ")

Call CreateSystemCatalogTables(metadb)
Call InsertSystemCatalogPopulation(db, metadb)
End Sub


But i want to run the following code but instead of refrencing the current access tables i want
to refrence the browsed external file.In another word i just want to run the below code but unfortunely the
CreateSystemCatalog() function refrences the tables in current db not the one that we justed browsed and loaded it!

Thanks kishor for u code. I tried this but i got error. Furthermore i want 2 buttons in this form. once for browsing the mdb file and one for firing the systemcataloge CreateSystemCatalogTables(metadb), InsertSystemCatalogPopulation(db, metadb) function. currently the code is working based on one button!I be happy if u help me fix this error.Thanks

if we are using db then there is no need for using adodb.connection. and can you find on which line the error is generated. means on the function name or the adodb declarations.

[kishore.kr]

if you want to use two buttons then declare the metadb in general declarations.

Thanks kishor once again. I tried it and same error again!! It does not show me which linke. It happens when i jus click button command0!!

[kishore.kr]

hi
i think the error is simple. either you have not selected(tools->references) microsoft activex data objects library(9.0 like that) or the dao library. check it.

wow. Many thanks it worked well. could u tell me how did u deal with the browse part? did u use any wizard ? i never knew of this way . There is no moduel involved as i can see!

if i want to select one of the tables from list box and do some thing against it for example show its fields in massage box by pressing another button how i can re refrence that mdb. should i place

Set w = DBEngine.Workspaces(0)
Set d = w.OpenDatabase(cd.FileName)


in the event functon of the new button ?

Furthermore, for example if i want to run the following code against the browsed loaded mdb how i can refrence the browsed loaded mdb file ?As u see now it uses current db now !!


Private Sub Command1_Click()
CreateSystemCatalog
End Sub

Sub CreateSystemCatalog()
Dim metadb As Database, db As Database
Dim metadbname As String
Set db = CurrentDb()
metadbname = Left(db.Name, Len(db.Name) - 4) + "_meta.mdb"
Set metadb = DBEngine.Workspaces(0).CreateDatabase(metadbname, dbLangGeneral)
MsgBox (" System Catalgoe tables created succesfully! ")

Call CreateSystemCatalogTables(metadb)
Call InsertSystemCatalogPopulation(db, metadb)
End Sub


thanks

[nagasrikanth]

thanx..

If u see the form in design view , there is a control named COMMON DAILOG CONTROL.It will do the browsing part..

and coming to u r second question,see the attachment ..whenever u click on the list box..it will messages each and every filed in that particular table..

and coming to u r third question , declare u r variable globally...(in the new attachment all the necessary variables are declared globally)..
so that u can use the same database in the total module..

in case of queries plz revert back..if no queries...Please rate the post..
