I am wondering how you would go about making a search function for a grid in VB.net. Right now, I have it so that the person clicks a button and they see the last 50 records they've looked up. This works fine. I also have a search button that works like this[code]...
View 2 RepliesI'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.

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 have a VB.NET search routine, part of which is provided, below, that checks all Text cells in a DataGridView for a given string (inclusive), using a basic set of nested loops to perform the search:
' Search for the first occurrence of the given string
For Each row As DataGridViewRow In dgvMembers.Rows
' Skip the new row
[Code].....
is there a way to replicate this behavior using LINQ? Basically I would like the query to select (or return) the first DataGridViewCell whose text contains the search string. I've done some tinkering with sub-queries and the like, but I'm still having trouble wrapping my brain around the concepts (too many years of writing T-SQL, I guess).
I have a form with 2 datagridviews on it, each connected to to table in a database: dgv1 and dgv2.
- Dgv1 has a column called "Senders" and a column called "Recievers".
- Dgv2 has a column called "Recievers"(this is a master list of recievers) and a checkbox column in it.
Basically, when you click a checkbox in dgv2, it copies the name corresponding to it(from "Recievers"), to the "Recievers" column in dgv1.What i want to happen is, when the user selects a name from the "Senders" column in dgv1, it should automatically search the "Recievers" column (also in dgv1) for names(each name is on another line in the cell), based on the "Recievers" columnin dgv2, and if it's in the cell, it should check the checkboxs corresponding to the name in dgv2.
I created 2 forms in Access 2003 (Form1 & Form2) for the purpose of creating a 'smartform' of sorts for my company. In essence they can click on a search feature in the top cell and input an employee ID # which automatically fills in about 10 to 15 fields.
- There is only 1 table attached to the forms.
- The group I created this for is uncomfortable using Access.
What I would like to do with VB.net:
- I thought I would create an internal webpage using VB.net so they wouldn't need to log into Access [the DB would be stored on a separate server.]
- I would need a clean & simple interface that has 2 buttons, one for each form.
-When the form is called up I would need a search feature "EMPLID _________" which would connect to the Access DB table and retrieve the correct information.
-Id also need to have the form printable & have the ability to search again or return to the front page.

My application involves a spreadsheet on a VB form. I installed the COM add-in for the spreadsheet okay, and I see it in my form.Now, I need the following feature: When the user clicks any cell on the spreadsheet, a defined function will run. This is for scheduling events in a calendar. The user can click on a cell in the spreadsheet, the function will evaluate the text string in the cell, then decide what to do, based on the text.

View 1 RepliesI 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.

View 21 RepliesI'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?

View 1 RepliesI 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()
