I have a table of 51 data points all numbers between 0 and 8000, i have stored the data in an array of ushors's, and on my form i have 10 numerical text boxes, So that the user can change the values in the table every 5th value. Using the value changed event the program then re-calculates the values in-between.
What i would like to do is show the table in a data gridview and allow the user to change the values in the array using the datagrid view, i know how to create a table but not how to link the table, so that it can change the values contained in the array.
Below is the code i am using to create the table:-
Option Strict On
Public Class FrmViewTable
Private BindingSource As New System.Windows.Forms.BindingSource 'Create a binding source for the tabel & dataview
[Code].....

View 5 RepliesI'm using VS 2005 and I've created an Excel spreadsheet and written a lot of data. I've also modified some of the cell interior colors via commands like this:
objWorksheet.Cells._Default(Bline + 2 + i, 1).Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.White)
But what I am finding is that the borders are getting wiped out.

It's purpose is as follows:It basically is a "check list" for installed program's, and files. I image machines on a daily basis, and me making this application will save me hours, and hours of time.The basics:My program basically has 2 forms. 1st form, will be tabbed with "clients" or, different model of PC's. Each tab will have it's own checklist. I know how to pull external files already, though, that's not my issue.Basically, when I click "check list" button, it searches for an "adobe", and "Labtech" Directory. If it exists, it will throw the result into form2.richtextbox as Adobe is installed, or Adobe is not installed. Also, Checks if the second program directory is there, and then imports the info into form2.richtextbox on a seperate line. My question is, how do I change the color of the text per line?I.e. make Adobe is installed turn GREEN, and Adobe is not installed turn RED ect.
Form2.Show()
Form2.Show()
If Directory.Exists("C:\Program Files\ATI") Then

View 1 RepliesWhat I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:

VB 2010, Trying add custom colors to a dialog box, save and reload on opening. The "add custom color button" just adds it to the boxes on the left and does not save it for future use. If the user select that color having added it the left you can then get the integer value and add it to the code
ColorDialog1.CustomColors =
New
Integer
() {CustCol1, 16646145, 16580610, 16645891, 16711426, 65536, 6699546}
And save for displaying next time. but it does not return the same color.
Why does it return a different color, it displays the correct color when used at the time of saving? Is there no way of saving all the custom colors, if a user puts several in the boxes on the left? You have to make sure you select Basic color first otherwise it changes existing custom color or if you select a blank box you cannot select anything.
When custom colors are added via code as above it goes along the top row first but when you click the "Add custom color button" it adds the first color to first position of the top row and the next to the first position of the bottom row.
