I am working on a project where I create image files from calculations done from user inputs. The work is saved as jpg images in various sized and I want to add EXIF data to the saved filed and later on retreive these data again so the user can continue working on the basis of a re-opened image file as I hope to store the project variables as metadata in the image file.

View 17 RepliesI am trying to create a LINQ query statement that retrieve intersecting data from 3 datatables (dt, dt1, dt2). My first attempt to do so with the following LINQ query statement was successful: [code] However in my design, I would need the LINQ query statement to be dynamically generated, because I want a user to be able to retrieve intersecting data entries from VARIABLE number of datatables. In this case, the first option is not as good as the "INTERSECT" query operator, with which I can just easily connect each SQL query statement with a "INTERSECT" operator. The problem is that my second attempt using the "intersect" operator fails, and after many trials and errors I still can't get it to work. [code]
View 5 RepliesI'm using the ExifTools code to read and update the EXIF for JPEGs in a VB.NET project I am developing. So far I've been successful with doing what I need to but I'm having difficulty with the last thing on my wishlist- the "Keywords" or "Tags" entry. The "Tags" property (as accessed by file right-click->properties->Details and just below the rating stars) is populated with information but if I use the PropertyItem for Keywords (Value 40094) with the ExifTools GetPropertyValue() function, it returns nothing.
It's pretty obvious that the "Tags" entry under file properties is not the same thing as what EXIF defines as "Keywords" but I have not been able to figure out what the correct PropertyItem value to pass is.

I have been looking for weeks for a way to update the exif metadata on a picture. There have been some individuals who tried to help, and there were others who simply referred me to a website, without any knowledge of the problem, or a possible solution.
Now I will take a different approach.
I will PAY for a working library. I want to be able to do these things from the inside of a VB program. Does anyone know of any commercial packages that will allow me to EASILY update the metadata on a picture? I am sure SOMEONE has already done this successfully. I just don't know if these companies wrote their stuff from scratch, or purchased libraries themselves.

View 2 RepliesI have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.
I've almost finished my multimedia project. On the photobrowser (which constructs thumbnails of every photo in a folder and draws them onto a bitmap which I then make persistent and from which the user can select a thumbnail and the image is shown in full on a new form). You can print the bitmap consisting of 100s of thumbnails or the full image associated with a thumbnail. The onloy thing missing is getting all the Exif info - which is proving more difficult than I expected despite the propetyitems in vb.net. Yes, I have set the encoding to UTF8 etc.
