The Database In Application Becomes Read-only?
Apr 23, 2010
I've created a project in VB .NET. when i build it and run the .exe everything works fine but when i install it the database becomes read only. I've used the VB 'setup and deployment' project to make and installer and i also tried InstallShield but the occurs in both cases. i looked on google but can't find anything that makes sense atleast. i think the application can not create _log.LDF file. Anyone come across this problem before?
error: System.Data.SqlClient.SqlException: Failed to update database "C:........." because the database is read-only.

O/S WIndows 7
SQL Server : SQL Express 2008 R2
VB 2010 Express
SQL Server is located on the workstation so the code and the DB are on the same PC
Created a DB connection using the wizard. Tried this with Windows authentication and SQL authentication using sa
Created a Dataset and dragged the grid onto the form1.vb.
In SQL Sertver Management Studio I can update update tables using the same credentials as in the VB connection string
WHen I try to update a record in the VB Dataset it returns the error cannot update database because it is read-only
I have checked the files and folder attributes in SQL Data folder. Nothing is set to read only
I have checked SQL Server Database > Properties > Option > State > Databse Read only = false
I don't what I'm doing wrong here but I cannot get VB to update data via the dataset.
Inotice in SQL Server that the DBname now includes the full path "C:PROGRAM FILESMICROSOFT SQL SERVERMSSQL10_50.SQLEXPRESSMSSQLDATAPAYABLES.MDF" and not just the DB name. Is this becuase VB Express requires you to point to the physical DB file?

[code]After spending hours of research.I finally figured out the vb.net version on how to read a 64 bit registry with a 32 bit .net application. The importance of this is when you try to write to one part of the registry, it gets redirected somewhere else in the registry, which is super annoying.[code]

I am trying to read text from a 3rd party application. I can create a catalogue of all possible letter variations. I can store every possible character I encounter as a small bmp, or perhaps as an array/matrix of pixel values. For example:
xxxxOOxxxx
xxxxOOxxxx
xxxxOOxxxx
xxxxOOxxxx
xxxxOOxxxx
the letter "I" could be represented in a 10x5 array or matrix as above. Where x represents a wildcard pixel value, but O represents the expected/pre-defined RGB value.
I want to search specific areas of the screen, pixel by pixel where I expect to find the information I'm after. And convert this to usable information. What method gives the best trade-off for simplicity and speed? And how can I implement this method? How do I search for a bmp within a bmp at specific coordinates?

Even if I create a new one from scratch. How can one project open database files without error, but the new one I made can't?This is the code I have for both of them.
