View 6 RepliesI have three Tables in the MS Access database as below:
Company_Data
Name|Age|Department|Salary
User_Data
[Code].....
and i have a compare button on the VB form. Is there any code that can compare the Company_Data with User_Data and copy all the records not found in User_Data to Changes_Data table. When updating it should update the "updated on" Column to the current Date.
Same needs to be done in the opposite way. Compare User_Data with Company_Data and note the diff. No Need to update Salary in this case.

My approach is to setup three different queries and save to three different variables and then save the data in the three variables into the new table.

I am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.
Dim
SQLconnect As New SQLite.SQLiteConnection()
Dim SQLcommand As SQLiteCommand

View 3 RepliesWe are presently developing an application, let's call it APP1, which uses a SQL Database which have about 800 stored procedures, 600 tables, etc. APP1 was originally created in order to replace another application, APP0, from which we do not have source code but only SQL tables, Stored Procedures, views, etc. Previous programers of APP1 used some DB objects from this same database and added some other objects specific to APP1 because it becomes bigger than APP0. And we do not need APP0 anymore as APP1 does all what we want, and more.
So, now, we are thinking about a way to find out which objects are used by APP1 in order to remove objects which are ONLY used by APP0.What is the best approach to discover all objects used by APP1 without having to open every single class and form?
Once we will have a complete list of these objects, it will be easy to use a program we bought which detects all dependencies for all SQL Objects specified directly from SQL and remove objects which do not return from any dependencies. Any ideas of how I could get this list without having to go through all our program that have many, many, many classes and forms?
Note : I know, in a perfect world, all calls to PSs and tables should be in a DAL but in the case of the application we're presently working on ... this is not our case! Yippy! (sarcastic yippy) ;)
Note 2 : This application is not using any ORM. So all queries are directly using SqlCommand. So any call to any DB objects are in string format.

Okay what i what to do is to compare one picture to another continuously untill it finds a change and then launches my code. Picture 1 - A picture i put to the form Picture 2 - I wont this to take a picture in a certain area and compare it to the first picture. lets say the first screen shot it took didn't match 'Picture 1' then it will keep taking pictures until it finds something different and when it finds something different it will launch my code.
I dont know if this is the right way to go since i heard something about pixel scanning but that's to hard since you have to find the exact RGB of that pixel. Also theirs like billions on the screen so it would be hard to find a change of color on the screen and then launch a code after that and keep repeating.
