DB/Reporting :: User Defined Searches?
Apr 23, 2009
Im using a simple access database with only 2 tables and I creadted a form with a datagrid to show all data inside the tables, and now i want to create search buttons for each field of the table . like, "seach by Name", Seach by date" etc... i tried to use the simple code
Code:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim cod As String
cod = InputBox("Type the Id to search: ", "Search By ID")
If cod <> " " Then
[code]....
My biggest problem now is that this code works very well to search by id (which is my table primary key), but now i want to search by other fields and this code only allows to search by primary key! Is there any way to use something similar to this code to search by other fields?

I am trying to redirect command line output to a list box in a vba macro, and I've found some code that I think might point me in the right direction, but I keep on getting the same error. When I use this code [code]It gives me the error in the title and highlights the first declaration line.What does it take to define a new "process".

so my program takes what the user enters into a textbox and searches through the data i have stored and if it matchs one of the peices of data it displays the apropriate data to the user. This all worked fine till i changed the textboxes to be added dynamicly to the form when it is load and i put all textboxes in a collection. So now when the text is sent to the search sub it sends the data over but always returns that it didnt find a match. But if i go into the search sub and just tell it what to search for automaticly it finds it no problem.

I need some guidance on the best way to proceed with searching a file content. I have a large file (see attachment) that is in text form, some of these files could be upto 50 times as big, therefore creating a huge file. These files contain information that is produced from another application and therefore I am unable to change the format of the file.

I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.

I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:
Quote:
Private Sub btnDisplayRqst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplayRqst.Click
Dim sr As IO.StreamReader = IO.File.OpenText("PRESIDENTS.TXT")

example of a user-defined exception in VB.Net. I already have two examples that I was able to find online, but other than that, I cannot think of any more. I need to find at least 5 to put in my notes, and then submit to my teacher.The two I have so far are: invalid login information (such as improper username or password), and expired credit card information on an online store.

I'm a new user of VB.Net. I do have doubt on accessing a user defined Function or Sub. In some place of program, I do see the term "Call" when using the Function/Sub. In some other place without "Call". But both works perfectly. May I know the difference between the two.

I apologize in advance about asking a newbie question. I am a less-than-intermediate programmer who has done most of his work in VB6, and now trying to wrap my mind around the new concepts of the NET languages.In VB 2010, I have a Structure called "Direction", with one data member -- an integer named "Value". It's supposed to represent a value of degrees from 0 to 359.
Public Structure Direction
Private d As Integer

Well I had a thread going that branched out to this topic, so rather completely veering off the main topic there, I felt creating a new thread was adequate.So as the title says, I'm trying to create a user-defined type. It's not a simple type at that but a user here had showed me a way to fix all my problems. That was to create a type BigDecimal. Which my initial thought was to utilize the BigInteger type. Being that the Integer Part, and Fractional parts would be split off into two variables, both BigIntegers. Which would be combined at the end as a "decimal". However I have many many questions see that this is my first attempt at truly creating a type of my own. So as of right now I'm basically swinging in the dark here.

I have a database of 7 items that I want the user to be able to choose the order in which each is listed for use further along in programming. I'm thinking of using combboxes bound to the database. I found out that each combobox will have to have its own dataset otherwise they will all show whatever the current one that has focus changes to. Is there an easier way to be able to do this or is having 7 datasets bound to the comboboxes the best way? For this purpose I don't need all the contents listed in a DGV, only need the component name for now if this helps. Database programming is new to me and I'm a hobbyist programmer from VB6 days making the transition.

The main function receives data, uses additional functions to calculates the result and gives it back. But at one point, the function needs data from the SQL Server. I wrote a second UDF, made it visible and deployed it to the SQL Server. I see now two functions under > programmability > functions > scalar value functions:
1. The main function (IsCalcDay) and
2. The function with the data access (IsHoliday)
If I call directly the second function from VST in the debug mode, it works fine, bur if I call it via the main function, the code stops if the connection will be opened. The error is "Data access in this context is not permitted. The context is a function or method that is not marked with DataAccessKind.Read SystemDataAccessKind.Read or a callback to retrieve data from the FillRow method of a table-valued function or a UDT validation method." (translatet from German, probably slightly differnt in English)
VST (2010 prof) and the SQL Server (2008 R2) are running in my virtual W7 maschine.
Here is the code of the second function:
Imports System
Imports System.Data
Imports System.Data.SqlClient
Imports System.Data.SqlTypes
[Code]....
Why can I open the connection if I call the function directly, but it fails if the function is called from another function?

Maybe I have missed something obvious. Currently I am using the feedback interrupt to change the cursor to one of the Windows supplied cursors
Instead of using the pre-packaged cursors, is it possible to use my own custom-cursor (icon), and if so - are there any rules re size etc., or can I use something like a png/jpg etc.. ?

I would like to make a "deep copy" of a class object that I have defined. See Visual Basic 2005 Code below
Dim MyStuff1 as new MyClass
Dim MyStuff2 as new MyClass
mystuff1.getbyID(anID)
mystuff2 = mystuff1
Unfortunately the statement "mystuff2 = mystuff1" makes a "shallow copy" of mystuff1. Therefore, if mystuff1 is redefined then so is mystuff2. What do I have to do in MyClass to implement a deep copy method such that operations on mystuff1 and mystuff2 are independent?I would prefer something like
mystuff1.deepcopy(mystuff2)
or
mystuff2 = mystuff1.deepcopy()

I knew that the VB.NET has an error handling with Try..Catch statement. As I know, if there is any runtime error happen in the Try routine, it will only throw the error in the Catch. But what if there is no runtime error and I need to throw an error when I found the value of the calculation reported is invalid? Like for VB6, we can write the 'On Error Goto ErrHandler', so in VB.NET, how should we define similar method? For example, there is a simple mathematical calculation where the division of two numbers will never > 5. So if I found the result of the division is greater than 5, I want to throw an error to say the result is invalid.

I am very new to programming so sorry for the simple question, but I am at a lose. What the program needs to do is take a user defined starting and ending range, and then build a table based on that range. Inside the table each record will need to have two check boxes.
So for example the user enters in a starting of ABC01 and ending ABC03 and clicks the button the table is populated like this;
