VS 2010 : Getting Data To Show In Dgv?
Nov 6, 2011
I'm having a problem getting my data to show in my dgv. I've done this a few times, but Idk what's up. Here's my code, btw - I'm trying to start using more 'blah blah in my code.
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Select statement
Dim sql As String = "SELECT * FROM leads"
[code]....
The only thing that I can think of is that the database I'm using is an excel sheet converted to access.

I am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for.Is there a way to edit columns and rows manually ?This is a list of what i want to do :
1. First of all i want to change column captions. because they are like "Fld_name" etc.
2. There is a column that shows date. I want to write a code for it ( convert date type )
3. I want to add a button at the end of each row and write a code for it ( show detail about that record )

My system still show the "record has been added" and save/insert the data even if i chose the "no" button. I think I miss something on our codes. Should I add something?
Here's the scenario: If "Yes" (button) will be clicked, it'll save the data and clear the fields. If "no" (button), it'll clear the fields and shouldn't save anything.
Here are the codes:
Private Sub btnsave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnsave.Click
If newname.Text = "" Or newaddress.Text = "" Then
MsgBox("Please fill-up all the requirements.", vbExclamation, "*** System")
Else

I am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can type commands into a text box and have set up a button that sends that text to the serial port. This text is displayed in a big text box as well as the feed back from the serial port (multirom audio controller).
Here is an example of what I send and receive to and from the controller;
I send *Z01STATUS (query's the Zone 1 status of the controller)I then receive the data from the controller #Z01PWRON,SRC4,VOL99 (This tells me Zone 1 is on, Source 4 is selected and the volume is at level 99 I can easily create buttons to turn the zones on and off and control the unit. My problem is I want to make things change on my form coresponding to the data received. ie I want to display the current volume of each zone and whether thetay are on or off etc. How do I get the individual bits of data from the data received. IE how do I get the VOL99 to show 99 in a text box?

I want to show data in a grid. I tried DataGridView but i have some extra requirements which aren't supported:
1. Rows should be able to group together (like in a TreeView)
2. I can put icons in the cells
3. I can add color to the cells (like in a RichTextBox)
Does anyone know about a FREE (or a low cost) control which support those requirements? Maybe DataGridView does support those functions and i just don't know..?

I have the following coding which only displays the first character, the problem is the first value can be more than one character and I want to display the first value.TextBox1.Text = TextBox1.Text.Substring(0, 1)I know I could just change the coding to (0, 5) but this is not ideal for me as values with only 1 characters will have 4 spaces.

Alright it's been awhile since I messed with this project, so here goes. It's an appointment scheduler and everything works except two things: I can't edit existing appointments and it only records the current time, not the timeslot I click on.
If I try to edit an existing appointment it doesn't get the row data, just shows me blank text boxes. I assume I have to have those text boxes read the info from the database, but I don't know how to do that.
This is how it looks:
So, you double click a time slot and it looks like the second window. You can right click on an existing appointment to edit it, but when you do that all the text boxes remain blank like you're inserting a new one.
What code would I use to read whatever row's data I am trying to edit and insert it back into the boxes?
Here is the code I use to add new rows to the DB:
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim NR As TestAppointmentDataBaseDataSet.AppointmentRow
[Code].....

I made a web application were you can check if somebody paid for their e-ticket and if so once you push the send mail button the person will receive his/her E-ticket with all the information regarding the activities they ordered.
I just have one problem the mail that I send collects data from a data grid and puts that in a static array.
Dim testarray(20, 1) As String
And of course the code to get the data from the data grid into the array
A part of the html code to send the e-mail is as following
"<br>" & "</br>" & "Tickets: " & "<span style=""font-size:14pt;"">" & testarray(0, 1) & "</span>" & "Activity: " & "<span style=""font-size:14pt;"">" & testarray(0, 0) & "</span>" & "." & "<br>" & "</br>" & "Tickets: " & "<span style=""font-size:14pt;"">" & testarray(1, 1) & "</span>" etc.
The Testarray(0, 1) and up are filled with the corresponding amount of tickets and for which activity. As you can understand if for example Testarray(1, 0) and Testarray (1, 1) do not exists because there is no corresponding ticket amount and activity in the grid. But Testarray(0, 0) and Testarray(0, 1) do exists, the person will still receive a empty line in his/her mail
Tickets: 5 : Activity: Sleeping
Tickets: Activity:
I know that with a dynamic array maybe I could fix that problem, I was wondering if there is a work around so I can check if a Testarray is empty or not and then only when its filled with data it will write the line into the e-mail.
