Converting text from scanned image to editable text

Question

Hi all, I am working on a project where I want to be able to upload an image(pdf) of a form that was filled in by hand then to convert it into text that will be later saved in a database. I am hoping to use OCR for recognition but I've never used it before so any help will be appreciated.
This will be done in WPF and it's a desktop application.
Thank you

Answer 1

Gaurav,

Would like to understand few things.

Whether you want to delete the records in a table based on the count of rows (parameter)? irrespective of which 10 or 40 records to be deleted.

Below link has the sample stored procedure to delete the records (result of search query) from the table.

Hope it will solve your issue.

Answer 2

Another approach you can take is schedule the deletion of rows during a time when database is not used.

Example during Night.

Then you would not need to implement any extra logic.

But use this, only if deletion can be done later.

Answer 3

CREATE PROCEDURE spDeleteRecord
@DeleteBatchSize INT,
@DelayTime DATETIME
AS
BEGIN
SET NOCOUNT ON;
DECLARE @DeleteRowCount INT
SET @DeleteRowCount = 1

WHILE (@DeleteRowCount > 0)
BEGIN
BEGIN TRANSACTION
DELETE TOP(@DeleteBatchSize) SchemaTableName;
SET @DeleteRowCount = @@ROWCOUNT;
PRINT @DeleteRowCount;
COMMIT
WAITFOR DELAY @DelayTime
END
END
GO
