I experience some difficulties with property Item of DataGridView component.
The application is made in Visual Basic 2008 Express Edition and I'm using Sql Server Management Studio as DBMS.
I have made a query starting from my tables and I want to add the result of query in a datagridview in reference with what the user selects: (I have 3 textboxes and 2 datetimepickers).
Here's the code in button search:
(don't know how to add the 5 components in the dategridview and integrate the query in datagridview).
My form is this:
Here's the full code of search button:(where I have problems) (I made a reader to read my query and I need to store the result of query in a datagridview related with what user types in the 3 textboxes and selects from the 2 datetimepickers.)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim conexiune As SqlConnection 'for connection with sql server
I want to make a search form the user completes the 3 textboxes and 2 datetimepickers. (so five components).
Also I have a button called search and a datagridview.
When the user presses the search button it searches into those 2 tables (depending on what user typed in the 3 textboxes and selected on 2 datetimepickers).
Example of search:
The user searches like this:
When it presses the search button the results will be stored in datagridview(first textbox is the field DB-20-RTS from table PatrimoniuMasini and the rest are fields from the specified columns (name of labels) from the second table FoaieParcursMasina -is the second row from this second table).
Here's the code in my search button (don't know how I can store the 5 things(2 datetimepickers and 3 textboxes in the DataGridView) . My problem is in understanding the property item of DataGridView(DataGridView1):
Dim conexiune As SqlConnection 'conexiune cu sql server Dim comandasql As SqlCommand 'cerere -interogare sql Dim msg As String ' msg- variabila dk suntem conectati sau nu
I performed a search by completing this information in my form:
TextBox1: the user types DB-20-RTS DateTimePicker1: selects 7 april 2004 DateTimePicker2: selects 7 april 2004
[Code]....
I don't have errors of syntax in my code the only problem is when I press the search button (it doesn't store me in the columns of datagridview the 5 things I want).
This is the code I posted before. I have a thread open but it is confusing. I have a search of a datagridview. The search works. Now I would like to highlight the corresponding row of the search result. Scroll down to the highlighted row. If there are multiple results to the search critiria the next one should be highlighted.
if i want to search for any thing in the database for example i write in the textbox the key ward how i want to search it then the result show in the table 'DataGridView'
I am extracting datas from the table to display in datagridview1 as shown in image1. Now I want to search the datagridview1 and display the result in datagridview2 as shown in image2.
I've created a form which correctly displays all my fields in a recordset. I can scroll through them, add new records, delete records, etc. etc. and everything is fine. I now want to add a Search field to the form so that when the user enters a search string, it automatically searches through the dataset and refreshes the display to display the appropriate search result (i.e. populates the currently open form with the appropriate record).I have a simple database, and I have created a form (not a datagrid) for displaying the records (and to make it easy to add new records and browse through with the next and precious record buttons). BUT, to put a simple textbox on the toolstrip and enable the user to write something in it and then click a button to display the entire record containing that "something" seems imposible.
I have eleven columns in my table, and I want to search the one with the Primary Key, so there will be no confusing wich record to display.
I didn't get the result I want from the following code:
Private Sub tblView_SelectionChanged(ByVal sender As System.oject, ByVal e as System.EventArgs)Handles tblView.SelectionChanged Dim st As String = tblView.SelectedRows.ToString
[Code]....
I wanted the data I selected on the datagridview row to be display in the textbox, but it displays the error message that st(0) produces "S" which is incompatible to my RackID data type.
Im trying to get the result of an SQL statement and store it in an integer variable "count" in vb so it can then be displayed on my website showing the user the total Open records:SELECT COUNT (recordID) FROM [tbl_Records] WHERE [Status] = 'Open'
I have a Search function on my database.It countīs how may search result you get but now i want to load one column from each search result ( for each row in a DataTable ) into a "ToolStripDropDownButton.dropdownitems".[code]
I want to take on a challenge.My ide is to me a program that search a folder for files with a specific file type ( like ".mp3")and then add information to a listview(Details). the information i want to add is:
cmd.CommandText = "SELECT * FROM [strfg].[dbo].[Myfunc] (@MyParam)" Dim myparam As New SqlParameter("@MyParam", a) cmd.Parameters.Add(myparam)
The function (runnig on SQL server) returns a table with four columns, one row.How do I call this function from Visual Basic? cmd.ExecuteScalar() is obviously not correct. In c++ I use a recordset. What is the equivalent in vb? Does anyone have a short example?
Is there anyone here, can share some tutorial or ways to convert search result which is in xml format to html view which is more easier to view compare to xml view.
i am trying to make a search form with 1 label(surname) and textbox. i have 1 gridview on the form aswell. can you plz provide me any code so that when i type in textbox i should c the result in the gridview. wat i have done right now is. i have added data source and i than dragged the dataset.but when i load the form i already can see the data loaded on grid view .it than filters depending on the textbox. i want this gridview to be empty when it gets loaded.
I 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?
I am trying to search an array and then say whether the result was found or not.
So far i have:
Option Explicit On Module Module1 Const MaxAnimals = 20
[Code]....
Now i have looked online and all of them seem to give you like ready made things on VB but i have not used them yet and i know there is an easy way of doing it as my friend managed to do it before but i can't get hold of him.
Basically it is a program (There is more of it but this is not necessary for this) which puts the names of animals into an array then you can either add another animal, or in the sub i am doing at the moment view all the animals in the array but i can't work out how!
I'm having a problem with part of my application I'm trying to get the directory entry for a computer object in AD (it could be mutiple computer objects based on whether or not the users passes a wild card for the object name). These names would be added add a child node of the parent node "Computers" in the tree view. I'm just having problems with using the search results...
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim parentCNNode As TreeNode = New TreeNode("cn") TreeView1.Nodes.Add("Computers")
I have the following code: indexOfSearchText = TextBox1.Find(item, start, TextBox1.TextLength, RichTextBoxFinds.WholeWord) If indexOfSearchText <> -1 Then startindex = indexOfSearchText End If But I want just the first result, if I have an example text: then it searches twice "is", I just want the first "is".
I'm currently attempting to use a .NET WebBrowser to display help information (stored locally in html files) for an application I'm writing, however I'm experiencing two problems, both related to hyperlinks.
Firstly, I have a search function which returns the correct URL in the format file:\C:... I can copy and paste it into a browser, and it will navigate there. Yet clicking on the link within the control itself does nothing at all.
Secondly, the HTML files all contain relative paths to other HTML files. These of course do not work as I just end up with file:\C:help.html which gives me a 'webpage is unavailable.' But I can't think of a way to get it to work without parsing the HTML file and concatenating the path to the directory on to the front of the link.
Just to clarify, in the first problem I am dynamically building a search result page as the user types. The HTML contains several results similar to this (yes, it's unfinished, I'm just showing you the link part): [code] Now, when I click on that link in the control nothing happens, it doesn't give me a 'webpage is unavailable' or take me to the actual page. Saving the HTML, however, and opening it with Chrome, IE and Firefox works fine.In the second problem, I have a different help file for different sections, each containing relative links to several others. VB picks these up as direct paths, and attempts to go there from root, i.e file:\C:file.html. The only solution I can think of is to parse the file and use WebBrowser.Navigate(Path.Combine(pathToDirectory, nameOfHelpFile.html), which seems a lot more inefficient than it should be.
In my form, I have textbox + combobox to enter datas which are saved to ms access. I have search option too. Also i have DataGrid to show the result of the search. What I want now is, 1. To show the search result in the textbox/combox as well (I already am able to make the result show on datagrid)2. When there are multiple result showing on DataGrid, if i click on a particular result on DataGrid, let the textbox/combobox automatically loads the details of the one i clicked.
i have form1 with combobox1 and rtb1 i would like to search the rtb1 for combobox1 selected value and return the first 9 characters from the line with the result.
COMBOBOX1 ADRIATIC AMERICA APAC-ANZ
[code]....
so if combobox1 selected.value = "BALTIC" then i would like "1209-4756" to become a named string (eg, cda = 1209-4756)
