Varbinary to Excel file 10 Years Ago by jaejoong Hi, I would like to know to extract varbinary(max) to an excel file. I am currently creating it in windows application. Thank you! Re: Varbinary to Excel file 10 Years Ago by ddanbe What do you mean by > extract varbinary(max) to Write a maximum binary value to an excel file? Re: Picture Box Read Image directly from Varbinary 13 Years Ago by Momerath varbinary takes values up to 8000, or 'max'. This has to do with DB paging, but you don't have to worry about that. Just set it to max and it will hold images up to 2GB (1000 MB).

Typically binary inserts are done with applications and not directly from TSQL, and inside of the applications you use ADO.NET/Native SQL parameters. You set the parameter to a byte[] array and execute the query. This all depends on the language you are using though. What language are you developing your … Re: MSSQL Server problem writing VARBINARY data. 14 Years Ago by LED555 So I looked up the ASCII meaning of [B]0x03[/B] and [B]0x80[/B] that my SQL Server replaces my [B]0x00[/B] with. [B]0x03[/B] means "End of text" and [B]0x80[/B] has no meaning, it's just a character (C with an accent mark below it). Does this ring a bell to anyone?

Warning though, reading cuts off when the buffer is full so if your image turns out to be bigger than a megabyte you're not going to have the full image and it will throw an exception like it is now. Re: Picture Box Read Image directly from Varbinary 13 Years Ago by WildBamaBoy Try increasing the size to 1048576 and see if it works.

Re: MySQL VARBINARY 11 Years Ago by pritaeas > didn't found use Of course it has a use. It's an excellent column type to store encrypted data.
