Merge This Three File And Create One Database For All Years?
Jan 28, 2012
Suppose you have three file of a database with information for three years (imported information of one year to database and has saved as a new file). How we can merge this three file and create one database for all years with visual basic 2010?
Note:
1-Each database has three tables and there is relationship between them
2- The ID number in tables is Auto number
3- Fields in all tables for all files are completely the same

Suppose $800 is deposited into a savings account earning 4% interest compounded annually, and $100 is added to the account at the end of each year. Calculate the amount of money in the account at the end of 10 years. Determine a formula for computing the balance at the end of one year based on the balance at the beginning of the year.Allow the user to input the beginning balance and the amount to be contributed at the end of each year. You must a loop in this program. [code] I cannot figure out how to make the previous years balance become the next years and so forth.

I have a project that I am working on that requires me to delete records from the database if they are atleast 3 years old.I have something like this in DB2 SQL to get the date:
SELECT * FROM tableA
WHERE ADD_DATE < CHAR(CURRENT DATE-3 YEARS)
ADD_DATE is stored as Characters in my system, this is why I am converting I know it is also possible to get the date and format it in VB.net which is the language I am using to call the SQL statements.My question is whether it would be faster/better to get the date and perform the conversion inside the SELECT in SQL or would it be better to get the current date and convert it in VB.net and then use that date in the SQL statement. I'm thinking VB.net would be better because there are thousands of records that must be compared. I should be able to set it up in VB so that it only retrieves the date and converts it once but I am not sure what kind of performance hit each takes from these statements.

I am using this editor for the users to enter their text in the database interface environment that will both load/save/show them what they are working on in the form and also mail-merge into a Word document waiting for the content. I can do the first step and it works well, but how do I get MS Word to recognize HTML as formatting instead of just merging in tags and text all as text?
The tool has two relevant properties: one to get just the text (no markup, i.e. no HTML) and one to get the full markup with HTML. Both of these are in text format (which I use for easy storage in the Database).
ideas/directions I can think of:
1) use the clipboard. I can copy/paste the content straight from the editor window to Word and it works great! But loading from a database is significantly different, even when using the clipboard programatically. (maybe I don't understand how to use the clipboard tools)
2) maybe there is a library or class/function in Word that can understand the HTML as "mergable" content?

I have the same table in SQLServer and MSAccess database named "KHang" with fields : ID int identity(1,1) primary keys , MaKH char(4),TenKH varchar(50)
Here is my data :
MSAccess (" KHang" : Id-MaKH-TenKH)
1-KH01-tes
2-KH01-test
3-KH01-testing
SQLServer (" KHang" : Id-MaKH-TenKH)
1-KH02-testing1
2-KH02-testing2
I connect to MsAccess database using oledb in vb.net and fill data to DataSet1. So I want to update it to SQLServer database. I mean, the result will be like this:
SQLServer(table "KHang") :
(Id-MaKH-TenKH)
1-KH02-testing1
2-KH02-testing2
3 -KH01-tes
4 -KH01-test
5 -KH01-testing
How can I do it in vb.net?

I have two DataTables that come from two tables in an Access 2007 database. The first is my table for car data and it has been populated with a process that reads text data. i can use this table and update the db and no problems. However the car data table also needs those cars even when no points where collected. So I have a control table that has a list of all cars. Now i have two tables and if I use the .Merge function I get a third table with both sets of data. But when i try to update the db with this third table I get an error "System.InvalidOperationException: Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.

I am trying to have letter templates (word documents) that are stored in sql server VarBinary(max) to be accessed via a web application where they will be edited and saved back to sql server by directors of our company. Then various managers will be able to select an existing template (word document), make any additions, and mail merge with a list of customers to print or save the letters.
I am looking to open up word within a web page much like you would an email in outlook, edit it with spell check and the like, and then save it back in sql server. I am able to get word to open from a file but it is outside of the web application in a separate word document. I am storing the word document in sql server but am unable to open it in word without having to save it to a disk (why should you have to go to a disk for viewing or editing?). I am able to programmatically mail merge but that is in a separate word application.
I am finding bits and pieces on the web but nothing that will pull things together such as embedding word but in a windows app not a web app. Mail merge from a file not from a database, converting a byte array to word in a directory but not on a web page.

I am trying to essentially allow the user to merge data from a database onto a document and print it. I am new to working with the PrintDocument, but I believe this would be the way to accomplish this. I know how to print the text onto the PrintDocument at a certain position, but what I am trying to figure out is how to deal with the coordinates of the text I am drawing on the PrintDocument. Ideally, I would love to click on the PrintDocument in a PrintPreviewControl and capture the coordinates of the PrintDocument.

I need to write a method in C# to save all rows in a given datatable back to the database, but I cannot depend on the rowstate of each row. I can't think of how best to do this without extensive looping through the database table data or constant database querying.
I want to essentially perform the following insert / update for each row in the datatable, but more efficiently:

Is it possible to use VB code to code an application that can merge Hex data from a small (50kb) .dat file with the hex data from another small (50kb) file? This would require designating specific offsets, which I can pre-program, but If I could have user input this would be preferred.
Example.
Hex_1.dat
00 00 00 00 00 11 11 11 11 11 (Offset = 5)
Hex_2.dat
22 22 22 22 22 33 33 33 33 33 (To offset = 5)
Result file
Result.dat
11 11 11 11 11 22 22 22 22 22

With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file

In the old dos days you could combine 2 files as save to a third file:copy file1 + file2 file3. It still works in a dos shell. I did this: Shell("copy " & file1 & " + " & file2 & " " & file3)I got an error that file3 cannot be found. I know it doesn't exist I want to create it. So I created a bat file:copy %1 + %2 %3 and called it as such:Shell("ccopy " & file1 & " " & file2 & " " & file3). I still get the error that file3 cannot be found. First I don't see how it can tell from the shell that file3 is a file. How do I do this otherwise? Do I have to create a blank file before calling it?

What i need exactly is to make a program that have a button called "browse" , when the user clicks it , it prompts the explorer and let the user choose a .exe file, then theres another button called "merge", when the user clicks it, i want the file that was already selected to be merged with one that will be already on my project, and the result would be a single executable file, that will open the 2 .exe files when running it. Obviously i could do all the steps, but im stuck on the file merging part.

I would like to generate an Excel file using a database query in VB.Net. How can I do it? To be more precise: I would like to "bind" a query (much like binding a query to a GridView) to an Excel file such that the rows in the table occupy corresponding cells in a new Excel file, and save the file to my computer. And then, mail that file to someone. While I can handle the mailing part, it's the creation of such a file that I need help with. Anyone know how to achieve what I want to achieve? PS: I need to do this in VB.Net and I'm using SQL Server 2008.
