I have to write a program that allows a user to input DVD info such as DVD Name, Year produced, Running Time, and Rating. The user then clicks a menu item "New" to save that info to a file. Then the next time the user inputs new DVD info it has to append the new data to the same file. (I got this far and everything is working writing and appending data)Next the year has to be able to search by DVD Video name and it has to print the info in the text boxes on the form, if not found then a messagebox should say not found. When I use the sub procedure that I have created to search the record it always comes back as record not found although the record in in the file.

I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.
View 2 RepliesI created a small databse program, when I created the search field I wanted to display the results in "listbox" which I found some code that work perfectly
For each row in ds.tables("Tablename").rows
me.listbox1.items.add(row(1).tostring())
Next
but I also need to display "row 2" ACCORDING to the selected item from listbox in a textbox.
since the listbox is displaying the result of a search, it's been hard to find, how to do this?
Im working on a program that will display a price when an item number is entered in the search box. I have the information in a text file for the program to find it but am unable.

I am building a scientific calculator.
1. After I clicked the Sine button, I get the result in a textbox.. When the result is there, for example: 1 radians Sine = 0.8414.... I can still put numbers at the end of this result.. like button 5 will be 0.84145, so how can I disable that?
2. After I get the result from a calculation, the textbox should be cleared when I insert a new number.

Here is my while loop:

In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.
Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.

View 1 RepliesI am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)
I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?

View 2 RepliesI have an object that I'm instantiating in VB.NET. I'm trying to see if it's storing a particular value somewhere in it. If I look at the object in the watch window in the VS 2010 IDE, I see this huge tree structure with thousands of nodes, many layers deep.
I'd like to be able to search for a value "1234" in this huge tree structure. I tried using serialization to convert the object to xml, but it complains that it doesn't have a parameterless constructor, since this object is provided by a third party, I can't add a parameterless constructor.Is there any way that I can search this object? Is there anyway that I can convert the tree structure that I see in the vs 2010 watch window to an xml document, or a string?
