I've got a SQL Server and I need to save files somewhere and I guess I hsave two options
1. Save the file path
2. Save the file in the database.
Issues with option 1 are for complicated reasons the file path is not the same for everyone. I'm talking about saving 200-400 per month, is there any issues with saving them into a SQL Server Database that is used by internal employees only?
saving a file into database ?

View 1 RepliesI have buttons working that cycles through all the records and everything shows up fine. I also made a simple DB program to test what I was doing without all the extra stuff my current program has and it works fine. Updates the dataset and then saves to the database and reflects the changes. When I tried adding it to this program, I get errors when I click "Save" and "Commit".The "Save" (updates DS) error is: "Additional information: Update requires a valid UpdateCommand when passed DataRow collection with modified rows."The "Commit" (commits changes to DB) error is: "Additional information: Syntax error in INSERT INTO statement."Not sure what either of these mean, the same code worked fine in the standalone program. Looking at another site, they show the exact Save error I'm getting and say it's because I don't have a command builder, but it's up there. [code]
View 6 RepliesI have a Database which is a file, and my application uses BlindingSource and a navigator to browse the database.
I can edit the data with the Blidingsource. Just one problem - I cannot save that. The save button doesn't works, maybe because it got no code.
1.is it possible to save the database connection string to the textfile so that user would be able to know where the database is stored?
2. Any way to let the user decide where the database is stored? Since usually we, the programmer write the database connection string ourselves..
I have some pictureboxes on this form set up to allow me to browse for images, then select one and show it in the box. How can I save the picture I pick so it updates a database and will show that picture when I cycle through the data in the program? It would be an SQL database and it already has columns for the picture. I don't know if I should store the path to the image or the image itself.

I've made a code which updates my database using a dataset and data binding source. I can retrieve all fields in the database including the �Picture� field which is set to �OLE Object� however I cannot update this. The Picture field in the dataset is set to type System,.Byte. I�ve search these forums and found how to do it manually which I can do and works but when it comes to the BindingSource.EndEdit section it still tries to update my �Picture� field and fails due to a type failure.
It was �System.InvalidCastException: Failed to convert parameter value from a Byte[] to a String. --->� What can I do to correct this? Below is my code. Note the image saves under the hard coding but not in the second part of the code.
Dim connection As New OleDb.OleDbConnection(My.Settings.AirportsConnectionString)
Dim command As New OleDb.OleDbCommand("UPDATE Airports SET Picture = @Picture WHERE ID = " & TextBox10.Text, connection)

I'm working with VB Express 2008 and MS SQL Express 2008. I have an SQL database in my project which I manipulate in the project by adding to or subtracting from a particular table. The database's "Copy to Output Directory" property within the project is set to "Copy if Newer." Nevertheless, after I run the project, add to or otherwise manipulate the data, save changes to the database and then exit, the changes are not reflected in the table.

View 1 RepliesI have a form containing a listbox showing a list of image names. It's bound to the database table. When an image name is clicked it shows the image and imagename in a picturebox and textbox respectively. When no image is selected in the listbox, a new record can be inserted by browsing a new image in the picturebox by an openfiledialog, writing the imagename in the textbox and pressing the OK button. When an image is already selected, the record can be updated by pressing the same OK button. The data is saved into MSSQL Server 2005. Corresponding table fields are Keycode int autono, logoname nvarchar(50), logo image.Now the problem, when I insert a new data with an image everything goes fine but whenever I try to update an existing data with an image it throws an exception- 'A generic error occurred in GDI+.' at the following line- 'pic.Image.Save(ms, pic.Image.RawFormat)'. Surprisingly when I update an existing data without any image in the picturebox no exception is generated. I have crossed checked it and seems that the problem is just at one point- 'Updating the image from the picturebox'. My code to insert/update the data by OK button and to populate it by listbox doubleclick follows:
Code:
Private ms As MemoryStream
Private arrImage() As Byte
Private conn As SqlConnection

How can I make it that if a file exists, it will rename it with the exact name, but with a number by it? For example, my program takes a picture and names it "screenshot." I want it to make it say "screenshot1," if "screenshot" is already used, and so on. This is what I tried, but didn't work.

I am trying to use the BGW to save a DGV to excel file, but don't know how to do it correctly, specifically setting the savefile name this code doesn't work gives me:
'System.Runtime.InteropServices.COMException' occurred
- Make sure the specified folder exists.
- Make sure the folder that contains the file is not read-only.
- Make sure the file name does not contain any of the following characters:
Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process. I also tried doing the Save in the BGW RunWorker Completed event but then there is no file name.

When I save settings for an application using My.Settings.Save it saves it in %AppData%LocalCompanyname. Because I don't want my app to be installed and I want it to be a just .exe file, and it leaves some files on that computer. I like it to be in my apps location. Can I change that default location?
