Search Using Multiple Criteria?

May 27, 2011

I am doing a simple database project.I need to give the input in the database which is an access db from my input form and i have managed to do this part right.then i need to retrieve the details from the db using multiple search fields and show them in the datagrid view.I have 8 search fields(5 textboxes and 3 combo boxes). I also have included 4 other buttons which respectively clears the search boxes;clear the results of the gridview; show all results from the database;go to the input form and offcourse 1 search all the buttons working fine except the search button. actually when i click on the search button if i include sql query for all the search fields only the first one works and also if i have clicked any other buttons before clicking the search button nothing happens, no result is shown and it happens the same if i search once and clicked any other buttons and come back to search, no result. I need to show the results in the gridview depending on the user input on those search criterias. user should be able to search in any combinations.I am using the below codings in my search form. the combo boxes are not bound.datagrid is bound to database though.

Public Class Paxsearchfrm
Private Sub Paxsearchfrm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'LAFDataSet.Table1' table. You can move, or remove it, as needed.

[2005] Categorie Doesn't Change When I Search A Title

Feb 28, 2009

Hi, I have a project that works with a database. It groups al my films per category. I use this code to group everything by category. The categories are chosen in the combobox cboCateogorie.

Private Sub cboCategorie_SelectedIndexChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboCategorie.SelectedIndexChanged

If Not cboCategorie.SelectedValue Is Nothing Then
cboCategorie.DataBindings.Add(New Binding("Text", objDtsMuziekcollectie.tblCategorieen, "CategorieID"))
Dim dtvDVDInhoud As DataView

dtvDVDInhoud = objDtsMuziekcollectie.tblDVDInhoud.DefaultView
dtvDVDInhoud.RowFilter = "CategorieID = " & cboCategorie.SelectedValue.ToString
dtvDVDInhoud.Sort = "DvdID ASC"

objTblDVDInhoudBindingSource.DataSource = dtvDVDInhoud


End If
End Sub

Now I've made a textbox and a button which I can search with. But I want that my category in the combobox changes when a film is selected with that search. Now I already have this code to search with a joker sign.

Private Sub btnZoek_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnZoek.Click
Dim dtvZoeken As DataView
dtvZoeken = objDtsMuziekcollectie.tblDVDInhoud.DefaultView
dtvZoeken.Sort = "DvdID"

objTblDVDInhoudBindingSource.DataSource = dtvZoeken

dtvZoeken.RowFilter = "Titel like '" & txtZoekveld.Text & "*'"

End Sub

Ok, so what I want is the opposite off what I do when I select a category in a combobox. Now I actually select a film and this film also has an ID, namely DvdID and with that I want that the combobox shows the category where the film belongs to.

Build A Search Tool For An Application?

Apr 14, 2009

I'm trying to build a search tool for my application... I have a form with a bunch of criteria which the user may or may not fill in. The tool is looking up against one table in the database (OLEDB) so I wanted to pull in all the data from the table into a dataset (when the form loads) and perform the search on it. I'm not sure how to search through datasets... this is the code I have now:

Public Class TxnLookup
Dim daLookup As OleDbDataAdapter
Dim dsLookup As DataSet
Dim cbLookup As OleDbCommandBuilder


but I get an error on the foundrows = line ("Value of type 1-dimensional array of cannot be converted to").... is there a better way for me to search the dataset?

Build Search Engine For Word Docs

Apr 30, 2009

Is it possible to build a search engine to use on a DVD that contains Word documents, text documents, etc.? Say I wanted to find all documents with the name "James" in them. In the search box I would type "James", and it would return the results of everywhere James is found. Or suppose I wanted to find all Land Deeds where James is found, is that possible? All search engine examples that I have seen on VB Help has to do with databases, and I guess to an extent, my DVD would be the database.

I have a simple web for that has a dropdown list and a button on the form.The dropdown list is bound to a table in my database and holds three values with idents between 1 and 3 (Weekly,Monthly, Please Select).I have set my datasource to pull back item 3 (Please Select) as the first item in the dropdown list to prompt the user to select an option.

Aug 27, 2011

It's probably the most basic of things, but all I can find is how to launch a program, and not with the interactions I desire. Any tips as to the terms to use to search for answers, or links to topics regarding questions similar to mine, would be very appreciated. I have a wealth of info to read through, but I could use your knowledge to save myself time.Here is what I am trying to do:

Use a Button (A) to Launch a Prompt where User Selects Directory Path to an executable Program. The Selection is to be Persistent after the initial selection (saved in a settings file i assume?), and the Selected Path (or just "programname.exe") is to be Displayed in a Text Field (B). Launch Selected and Indicated Program via a Launch Button (C)
