I have 15 checkboxes of control array and at run time fill any 4 or 5 or 6 check boxes with color using colordialog. How can i send the colors to the sql server table using for loop using code at runtime
View 1 Replieshaving a bit of trouble with a bit of code. This is going to be a bit complicated to explain so i hope i can get the idea across. The idea is that the following bit of code uses an array called "lines" which has been loaded from a text file in a previous subroutine. I then want the status of each Checkbox to edit a set of lines in the array.

I have a VB2005 project that displays 16 pictureboxes in a 4x4 grid which display CD album covers. In VB6 I could set up a control array i.e. picCD(0) to picCD(15), which made drawing the CD covers a snap. How do I accomplish this in VB2005?
It seems extremely cumbersome to have code like: If Len(path(0)) < 1 Then
If Not IsNothing(PictureBox1.Image) Then
PictureBox1.Image.Dispose()
PictureBox1.Image = Nothing
End If

I am trying to port a program I wrote with old VB 1 and I have many control arrays in the program, and it was so easy to do this in older versions of VB, now I am trying to find how to do this and all the answers I have found are a major productions, to replace something that was so easy to do? I would think that microsoft would make programming easer with each new incarnation. instead they are making it harder. doing away with the DATA and READ statement, now it is much harder to fill an array with a loop, now you have to enter each item in an array ONE by ONE. they did away with the ON statement, I had several ON statements, I had to make complex Select case constructs. to replace a simple one word statement?
To make an array of controls in OldVB all you had to do is Name a Second control the Same as the First, and a dialog pops up and ask if you want to make an array, you click Yes, and that's it, what could be easier than this?
See asteriks ***below for the problems: There is text in CStr(rdrPlayers("PlayerName")) and the textbox for loop is 15 so why the extra textbox's 6 thru 15 (1 to 15 then 6 - 15 under them 6 is visable others are out of panel display I shortened my code below

It's working properly. But suppose user don't want to fill form and exiting from application.Message box keep on appearing till user enters account no.
I have created a set of scrollbars in a loop like this:
for i = 0 to 18
Dim scrolldmx As New VScrollBar
scrolldmx.Location = New System.Drawing.Point(x, y)
[CODE]...
And I have a handler to handle the scroll event. All good. I want to be able to set the value of them within the app. I can set the width of for instance the second scroll bar like this: me.controls("scroll" & 1).width = 100
But I can't see how to set it's value. I want to be able to "lock" several scroll bars together to make them all follow the value of the one I am changing.
I have found several examples of how to set text of a textbox across threads, but no examples of how to set other properties like the checked on a checkbox. What i am doing is listening on a serial port for data received.When the port receives the data I want to check a character in the string to see if it is a 1 ot 0 and set the checkbox to the proper state.I cannot figure out how to do that across threads.

Essentially I am searching an array for colors. If there is no input, on button click you get an error. If the color does not exist you get an error. If it exists then it tells you. The latter two events are not happening.

I am trying to create an array of colors. approach 2 doesn't work and I do not know why
Code:
'approach 1: works
Dim list As Color() = New Color() {Color.FromArgb(255, 0, 0), Color.FromArgb(0, 255, 0), Color.FromArgb(0, 0, 255)}
Code:
'approach 2: fails.. why?
Dim list() As Color = New Color() {Color.FromArgb(255, 0, 0), Color.FromArgb(0, 255, 0), Color.FromArgb(0, 0, 255)}
If instead I wish to create an array of strings, both approach works, that's weird.

View 2 RepliesI have a checkbox on my form chkActive, I want to deal with it in 3 cases. [Code] I don't have a problem with building the query, my problem is with clicking on the checkbox by clicking on the checkbox by mouse, I can only get Checked and Unchecked, I tried to use the right mouse button click, it did not fired (or I did not test deep enough) I know I can put a button to change the checkbox value to Indeterminate but that will be ugly. I can replace checkbox with combo, which is what i am thinking of doing but I just wonder: Cannot I set the checkbox state to Indeterminate by mouse any how?

I am using a monthcalendar control in my application to allow a user to select a day from the calendar that will load data for that day. the background is totally white (ugh). there is a backcolor property, but when i set it to say Cyan (yea right), the calendar still displays as white. I also can not set Forecolor, TitleBack/Fore color either.
I have gone to my project properties and turned off the "enable xp visual styles", and that had no effect. turned it back on...cant tell a difference. i am currently on windows 7 running VS2008 Team Edition. It would be really nice to change the look of this control to match the styling of my application.
I have created a procedure as below for ressting colors of any control I decide
Private Sub ResetColors(ByVal Control As Control)
Control.BackColor = SystemColors.Control
End Sub
But the compiler cant accept (Tooltip1) I think because it is not a control Call ResetColors(ToolTip1)<---- Error

View 3 RepliesI want to set a color on items and subitems being displayed within the listview control in a detailed view.Using the forecolor property setting would change the color of all the contents in the listview control. All I want is to display different colors on each column of the listview control. If I have four colums on the listview, it should display the contents on each column in a different color. I tried to do it on my own but it was unsuccessful. I'm looking for the exact code to set the color successfully. Currently, the code below is what I have to display the data on the listview. What line of code should I add on the code below to set different colors on items and subitems of the listview?

What would be the syntax to check inside a visual basic form panel for checkboxes and find which are checked? I understand how I Could use a for loop and an if statement, but I'm confused as to the syntax to check for each checkbox. for example:
Dim i As Integer
For i = 1 To 10
'Here is where my code would go.
'I could have ten checkboxes named in sequence (cb1, cb2, etc),
'but how could I put i inside the name to test each checkbox?

I'm looking for some code that uses progressively smaller steps that will converge 2 numbers to a tolerance of 0.00001. The starting difference between 2 numbers may be as high as 100 so using a step value of 0.000001 is not a good choice to start with. I thought about nested DO:LOOPs or a nested FOR:NEXTs but think there must be an easier way to achieve this. Has anyone coded a convergence loop like this?
