Implementing A Search Function
Jun 27, 2011
im trying to implement a search function to my booking program, wich retrieves data from a SQL database. I have the screan all set up and all the variables at the ready, the only problem is, im not sure how to execute it in a sqlcommand line.
I've got all the fields that are required, such as date, time but i also have two optional options, Room Type and Room Capacity.
How would i write a sqlcommand to search for available rooms that meet the criteria for the room to be booked?
Heres the code i have so far;[code...]

how to implement such a thing , i am currently programming a compact framework vb.net this is what i have done and am stuck,what ive learn is very basic and simple i am using a sqlce query to use it to search for any string matching entries in the database and then it will display it something like google search engine.And am using visual studio 2005, what ive done is that i will use the datareader to search for the rows in the database and then i will have to assign them to something that is similar to google search engine a dropdown list of similiar results but am not sure how. What im doing is for the user to search for a particular salesman name and then have a progressive search function to also help the user to complete typing rather than typing the full words

Dim connection As New SqlCeConnection("Data Source = My Documentsfinance.sdf")

I'm fairly new to VB and am having trouble implementing the Round function. I know that the syntax for what I'm trying to do is:document.write(Round("KwH",2))But my problem is that I can't get it working with the following line:.Kwh = items.Attribute("KwH").Value _So I want the output of whatever 'KwH' spits out to have only 2 decimals, despite the actual figure having 8

this wont be easy to explain clearly but here goes..i have something that works fine in VB but not in C#.i have 2 classes, each class implements a different interface. each interface exposes an Initialize() function that should get called automatically when the plugin loads. since each class has an Initialize() function, i can watch both functions get called in the log. this works fine in VB.
when i do this same thing in C#, only the Initialize() in the first class gets called. anyone have a clue as to why this might be happening?

as you can see the code is identical in both languages. why does it work in VB and not in C#?

I've decided to make my own simple scripting language parser. I've created about 50% of it and it works great! I need to implement "functions". What ever program uses my parser needs to be able to connect functions to my parser for customization. I've implemented "Lua", a scripting language, in a vb.net application of mine. To connect functions to the Lua Parser it used reflections.I need to be able to (by only knowing the name of the function and its structure) call a function connected through the implementing application.

I wrote a serializer (to Byte Array) for dictionaries that have a string key, but an object of some sort as its value.I've never implemented a generic type in a function or used a delegate before, so I'm a bit concerned about this being significantly slower than writing a serialization function for a specific type of Dictionary (Dictionary(Of String, MyClass) for example)Should this code be significantly slower due to the use of the generic type or the delegate?
[code]...
It works, and I could loop it and compare it to a more static Dictionary serializer, but I'm more concerned about when I start using this for a lot of different String/Object dictionary combinations, and it'll take me a long time to write a bunch of static dictionary serializers (that's what I'm hoping to avoid in the first place)edit: simplified intro text

I'm creating a search function to search through a binary file and find a record based on the users input. Surprisingly, that isn't the problem! The problem I'm having is that as part of this I'm using a procedure to display results in text boxes, and I'm getting the error "Too many arguments to private sub display customer"I've encountered this error before, but never really knew what it was... Here is my code.
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
FilenameCust = "F:\College\CustomersFile.bin"

Im making a search function for an application and they need to be able to search by any value in the DB in any of the three tables. Im wondering the best wayto about this. 2 of the 3 tables have the same columns while the last one is totally different. Below is what I kinda "thought" itd look like but no.
"SELECT * FROM cases, opencases, staff WHERE Crime ='" & txtsearch.Text.ToString & "'"
I need to query the results the user can search for anyterm and if it matches something in the columns it return it to the user. Im wondering if the best way to go about this is to maybe query all the tables and then put all the matching records in a seperate table and the dgv look at that table or how to exactly go about it.

I am currently trying to create a search function on a page in VB.NET which will allow me to search a database for a customerID from a textbox called txtSearch and then present it into a datagrid.
So far I can display the customerID's manually by using
SELECT * FROM Customers WHERE CustomerID LIKE 'A%'
but cant figure out how to replace the A with data which will be inputted into the textbox.

I have a VB .NET String. How can I search that string for a character string and replace it with another string?
For example:
Dim rValue As
String = sproc.ExecuteScalar()
' rValue now has the XML string <indracio fire height=23, width - 6>
/* This is the string that I want to search. Replace the words "indracio fire" with the word "lucion time"
How can I search this string for the words "indracio fire" , and replace with the word "lucion time" ?

I tried out the video tutorial from Beth Messi about how to create a search. The tutorial teaches us how to do it through query builder in which we just have to type LIKE@fieldname = '%' for each field we wish to appear on a toolstrip. A toolstrip menu will automatically be generated and placed underneath the form bar for us after we click ok.
Now, I would like to know how can I do this with code? I can use a code which will move the auto generated toolstrip into the tabcontrol but when I have more than 1 tabcontrol, that's when I start having problems - the toolstrips are starting to cover up the tabcontrol. I know I can move the datagridview lower but that is going to leave a big space above it.

I've just started developing web applications for the first time. Im developing an ASP.Net Website. Ive started transferring code over from my windows application and found a few errors. In my windows application I had a search function in a form where on click the text in a text box would search the first list box and print any matches in the second list box. [code] In my website an error pops up highlighting the line "words = lstSearch1.Items.Item(a)" and says that the value of the list item cannot be converted to string. How do I go about fixing this or is there a different way of implementing a search function in an Asp.Net website?

I am writing a program and I have the Read Function all written out. I need to have the write function. I think is I copied and pasted from the Read function I wrote.
I was able to Mass edit This:
Reader.Position = (&H)
NumericUpDown281.Value = Reader.ReadInt16()
Reader.Position = (&H)
NumericUpDown280.Value = Reader.ReadInt16()
Reader.Position = (&H)
[Code] .....
And there is at least 370 NumericUpDown's. Is there any way to search/find/replace all in one instead of typing:
Find what: NumericUpDown320.Value = writer.WriteInt16()
Replace with: writer.WriteInt16(NumericUpDown320.Value)
Each individually?
The write function will only write properly this way:
writer.Position = (&H)
writer.WriteInt16(NumericUpDown66.Value)
And not this way:
writer.Position = (&H)
NumericUpDown319.Value = writer.WriteInt16()
