Use Openfile Dialog To Edit A Database Connection?
Jan 19, 2012
How to change the database connection by using openfiledilog in windows forms? The application I need to do, need to connect to a database, each time with different path and different name to explore the opened database. All the databases to be accessed are having the same structure, but with different location (in the pc itself), different name, and with different data inside (but the database tables and relations are the same. I understand openfiledialog.filename contains the address for the clicked file, but failed to pass this information to update the Database conection with the new addrerss.

For some reason I can copy a file from a OFD box from anywhere other than my desktop.Could it be because I'm using the shell command and the file path contains spaces?I've declared the filepath as a variable. I know in a batch file you have to enclose names with spaces in "".
CODE:
Dim filename As String = "cmd.exe"
Dim p As System.Diagnostics.Process = New Process()

I am using vb.net 2003 and an Access database connected via Jet 4.0 OleDb. I have identified the location of my database using a relative path with [code]My program was working fine and I began making some cosmetic changes.I thought it would be a nice touch to add a PictureBox on the first form and allow the user to select the image that he would like to see when running the program.I added a menu item to "change the picture" and on a form added an OpenFile Dialog. I added code to capture the location of the selected file and used it to identify the image to be shown.I included a table in my database to store the file name and path which is loaded when the program starts.This all worked fine. I could change from picture to picture and the image would be updated each time in the picture box and in the database. I could access the database and perform all of the functions of the program.
That is as long as the image files that I selected were located in program startup directory. If I selected an image with the openfile dialog which was located else where then I could no longer contect to the database. I receive an "unhandled exceptions error". Below is the openfle code:[code]Can anyone help me with the proper way to get set up the open file dialog so that the results do not conflict with my database connection, or re-establish the connection?[code]

I am using vb.net 2003. In my program, the user can use an openfile dialog box to locate the address of a image and use it to change the display. The name and path of the image is saved in a database. This image is then loaded upon startup. If the image is located in the start-up directory the image change and saving to the database works great. But if the image is located some where else the image change occurs, but the path of the database has changed to the location of the image. Since the database is not located there, I get an unhandle exception error. What is the code to redirect the program to my startup path?

i am using access database for my program. now i have connected to the database in MDI form of main exe, and ir also works, user can log in, it gets verified etc etc etc. now here is the problem, when i load a form from dll and try to use any sql query on that form, i get message, "database connection is not opened". so what i did was, i added the connect() (a function i designed to connect to database) in the load part of the dll's form, it made the trick, query's started to run, everything went fine, and when i reload the form i.e after closing the form, i load it again from MDI form, i get error, connection already open..

I am unable to select a .ZIP folder with either the FolderBrowserDialog (FBD) or the OpenFileDialog (OFD). First off the FBD does not show any .ZIP folders when using it and the OFD does show .ZIP folders but I am not sure how to handle it's path. My question would be how can I handle the OFDs ".SelectedPath"??? I could easily obtain that info with the FBD "FolderBrowserDialog1.SelectedPath", but it does not allow the selection of .ZIP folders.. So now I am trying to do the same thing with the OFD but there isn't any code for obtaining the ".SelectedPath". Here's some code that shows what I am trying to do:
Private sourcePath As String
Private destPath As String
With OpenFileDialog1

I'm trying to edit my sql database using VB Forms.I went ahead and connected my database to VB and I see how to pull data from my database to VB, but I'm not understnading how to use a form to add/edit/delete data from the database.Basically I would be looking to add to a table:
Table Name: People
Row 1: First Name
Row 2: Last Name
Edit would be the same type of thing except I think I would pull the data from the database to populate a table, than how would I save the changes after I changed the information To delete I'm assuming would be similar to edit I would simply pull the data from the database than using a delete button would delete it.What I don't understand is how to create the SQL statement in VB so that it'll execute it properly in my database.
