How To Set Variable To Individual Row
Feb 16, 2011
Basically I'm designing a program atm for my college coursework and have been trying to get a search button to work. Basically, I need a way so that after the customer id has been found, my variable (in this case inc) needs to set itself to the row which the customer id that has been found is in. the idea is that it finds the row, and fills in the textboxes which I have with the data Here's the bit of code I have atm: (And btw, inc is set as an integer earlier on in the program)
Dim CustomerID As Integer
'asks for the customer's ID number so that their results can be found.
CustomerID = Val(InputBox("what is the Customer number?"))
Try
Sql = "Select * from tblQuotes WHERE CustomerID = " & CustomerID
[Code] ....
Hopefully with the text Whatever the Row Number is being replaced by actual code to get it to that row.

I can select any other item from the table without the error. "sender" has the same properties as "receiver" in the SQL table.

I have a a multiline textbox, I want to take each and every character that the user enters and on a button press it replaces them with a set of characters, like:
i with x75d
or:
f with g8r
but the only way i have figured out how to do something like this is using a character in between each character and the split method, like:
Dim input() As String
Dim txt as String
Private Sub Encode_Click(ByVal sender As System.Object, ByVal e As

I am making a HTML editor and thats the easy par ie saving as .html etc, but i want to also add in the thing thats in VB wherein it picks up the word your typing and make suggestions, i have made it so it can have a data base of a thousand words (1000) and you can add and it loads all fine. Now i need to add in the functionallity to read every Key, i tryed
Code:
If e.KeyCode = Keys.Space Then Scan = ""
But none of this works, is there a better way of getting the the key press and adding it to a string untill space is pressed in which the array is cleared.
Code:
Imports System.IO
Public Class Form1

So say i had a Tag stored that was "HTML" then as soon as i pressed the < key it would start checking my keys then if i pressed H it would display all word is the drop down box with H at the start then if i followed it with T then M it would show HTML in the box and maby a couple of others that began with HTM, if i then hit enter it would add in the L> thus compleating it and printing "<HTML>"

I am very new to VB, and am programming in VB 2008 express. Sorry if this thread is in the wrong spot I need to add two 40 digit numbers together and was thinking that the simplest way to do it would be to input them as a string and then convert the string to a single dimensional array where x(1) is the 1st digit in the number, and x(30) is the 30th digit, etc. I would do the same for the other number where y(1) is the 1st digit. I would then add the x(40) and y(40) (which are the last digits of the number) together and carry the remainder into the next addition (39th digit, 38, ...)

I have a mature VB6 program that depends heavily on flexgrids for the display.It appears that DataGrids are somewhat of a replacement for flexgrid?I need to update individual cells over and over and I don't see how to address a single cell. Appears to me that most samples are tied to a database which I don't have.If I set up a datagrid that is say 3x3, how do I read and write from and to say the center cell?

I have a vb.net project that loads "plugin" dlls at runtime to crunch some data in slightly different ways and return the results. To do that, all the plugins implement the same interface, so the GUI couldn't care less how the plugin arrives at its final dataset, just so long as all the plugins deliver it back to the GUI in the same way.
I'd like to set up per-plugin options in addition to the main program options. I have an options form that accepts an object of type System.Configuration.ApplicationSettingsBase and displays the contents in a PropertyGrid control, so it'll show any My.Settings object the same way. Question is, how do I pull the My.Settings object out from a plugin that's loaded at run-time?

I'm a bit of a newbie to using VB in Access, I have a database in which multiple people need to work specific problems which are separated into records from a form. What I want to have happen is that everytime a person changes the cboStatusName combo box to "Done", it will populate the current time into the DateCompleted field, and then it will lock both of these.

I am developing an application in vb.net 2008 express edition that displays utility meter information. In one column of datagridview it shows the meter type in numeric code. When the user hovers over the the individual cells in meter type column i want to be able to show more descriptive info on what that numeric code actually means.
As an example the cell in datagridview will show 1254 the actual description for this numeric code is "Landis Gyr Focus AX SD 2S 7.2Kh"
Below is my code so far, every other aspect of application is working except for above.

i am trying to validate a string that has been inputted into a text box so that it checks all of the characters in the text box individually. I have got the code to check the first character...
If Char.IsLetter(textbox1.Text) = False Then
MsgBox("Error! Invalide charecters present")
Exit Sub
End If If
I was just wondering if there is some sort of loop that i can do so that it checks all of the characters in the text box.
If Char.IsLetter(txtCustomerName.Text) = False Then
MsgBox("Error! Invalide charecters present in customers name")
Exit Sub
End If

I'm creating a project but I only need exe's as my final thing. I don't know how to put it in simple terms, but here is how I need it to be..The main window remains open i.e.frmMain. ther other forms are only called by an external program (LanSafe UPS Software) every time something happens (Either batteries gets disconnected or power fails). Each of these forms have to be separate executable files. This application is for sending SMSs using Fusion 100 modem. Is what I need possible?
