Also, it is impossible to come up with two different documents which would hash to the same value.

This remarkable feature of the one-way hash function can be used to determine whether a given document already exists in the database.

If you are implementing a file storage application such as a document archive or image repository, storing the files in the database is a sensible alternative to keeping them in a folder.

The advantages of the database approach are: To demonstrate Asp Upload's database features, a sample MS Access database, aspupload.mdb, has been included in the installation.

To Database Ex which enables you to save an arbitrary file on your system in the database, not just an uploaded file. The following code (sample file odbcexport.asp) exports all files from our sample database that were placed there by the previous code sample: Here, we have to employ ADO to scroll through all the records of our sample table and call From Database on each individual record. To Database is not the only way to save files in the database with Asp Upload.

The first argument for this method is a file path, the other two are the same as for the method File. Downloading a file from the database directly to a client browser is possible without using Asp Upload or any other third-party component, it can be achieved with ADO alone. Instead of ODBC, you can use the ADO Recordset object in conjunction with the File. Using the Binary property, a file can be assigned to the recordset much the same way as a regular numeric or string value, for example: This code is more intuitive as it does not require building complex SQL statements. This approach works equally well for inserts and updates.

In Microsoft Access, a file can be stored in a field of the type OLE Object, in SQL Server, the corresponding data type is IMAGE, and in Oracle Long Raw.

If the value is already in the database, we do not save the file.The full fledged premium dating script packed with powerful features and integrated payment system for easy transaction.We have induced a customized ad platform in the application, which will allow you to get advertisements and help you to generate revenue based on the traffic.A one-way hash function is an algorithm which uses a variable-length input such as an arbitrary file or text string, and produces a fixed-length output (128 bit or 160 bit for the hash algorithms MD5 and SHA1, respectively).Asp Upload offers MD5 hash value computation via the property File. The term "one-way" is used because it is practically impossible to come up with an input which would produce a given hash value.

Here is what odbc_looks like: Note the use of the built-in Replace function which replaces all occurrences of the ' character (single quote) by two single quotes to avoid a run-time error if the description contains single quotes. The second argument is a SELECT statement that must return one record containing a BLOB.
