I'm using visual basic 2005 express edition I am having trouble with comboboxes and a button I want the button to be disabled "button1.enabled = false" when the program starts Then when the user selects a listing in all the comboboxes have the button become enabled "button1.enabled = true"
I want to do a For Each loop where i can check whether each button is enabled or disabled. If the button is enabled then i have to obtain the values in the tags for each button. I have 26 buttons each containing different values (cash prizes).*IMPORTANT: this code needs to go under the button so every sixth time its pressed it checks the buttons.
Pseudo-Code:
btncase1.tag = 5 Begin while statement to go through each button Check each button to see if it is enabled
Put a Datagridview on a form, fill it with data. dgv1.enabled = True and dgv1.enabled = False are almost the same look to the eye unlike other controls (textbox,combo, listview, etc ...) where there back color changed to light grey and you can distinguish if that control is enabled or disabled but not for Datagridview.
i want to make only Library Reports Menu enabled if i login as user i.e if i seelct login as user then only menu item which user can access should be Library Reports and Student Details Menu enabled Property should be Flase
I'm trying to allow scrolling in a Multiline-TextBox even if the TextBox is set to
textbox.Enabled = False
This is not possible, as the Scrollbar is disabled with the Enabled-Command, too.The default solution here is to set
textbox.ReadOnly = True textbox.Enabled = True
but this doesn't really do the trick for me. With ReadOnly I can still select the text of a TextBox as well as place the cursor inside of it. But as I have normal (non Multiline-TextBoxes) and other controls on the same form I don't want that to happen. I want to have exactly the same behavior as all the other disabled TextBoxes.
For everything else, like mimic the color of a disabled textbox and so on, there is a legitimate workaround with the ReadOnly-Property, but I coudn't find any for selecting text and placing the cursor.
UPDATE:I tried to use WIN32 API but it didn't work as expected:
Imports System.Windows.Forms Imports System.Runtime.InteropServices Public Class TestTextBox
I'm trying to display the network adapters on the computer running this application. For that I want to be able to display all network adapters, no matter which status they have. Then I want to be able to enable and disable the adapters by pushing a button.
I've tried using System.Net.NetworkInformation, but it seems as though it only contains the one that's active.
I am making a configuration screen so that an administrator can easily determine what controls on a form are enabled according to a combo selection.
I have created a table (SQL2008 DB) to store the settings and need ideas how I can best implement.
The session form will start up normal with only a few controls enabled to start, but then when the user selects a "session type" from a drop down combo then the form will be configured for that type. Because there may be several different combinations, and I do want to offer the user the ability to add and configure more types as needed I feel like this may be the best method instead of hard coding.
Table Structure
SessionType varchar(25) not null PK ControlSwitch varchar(50) Not Null
(Edit: I may add an additional DB field so that I can specify the default value of a control also)
Now what I thought I would do on the config form is have a series of combo boxes and the label represent each control with a value of True or False, then when saved it builds a string like example 1,1,0,1,0,1,1,1 or True, True, False etc.
The string would represent ctrl1=on, ctrl2=on,ctrl3=off,ctrl4=on,ctrl5=off,ctrl6=on,ctrl7=on,ctrl8=on and so on.

Can the "Disk Cleanup" operation on Windows be disabled / enabled with a registry setting using VB.Net?I am using Windows 7 32 bit ultimate edition. but as a temporary measure I do not wish to do so.
Is there any way to check from .NET if windows update is enabled?
I want to prompt the users every time they log into my app that their computer might be at risk and give them a link to windows update website (or windows update application from control panel).
Preferably it should work on XP, Vista and Windows 7. Maybe there is a registry key or even better an API?
In my application I have more then one form/dialogs, of course. My start up (main) form is called "StartForm" and when I want to access to some other dialogs, I open up dialog and I put StartForm on ".Enabled = False" so that user can't access to that form even if he click somewhere on it (StartForm is maximized to full screen and dialogs are small so StartForm can be seen in background when you open dialog). Ok, this works fine until I click on my application "link" in task bar...then, only my StartForm is visible and it's ".Enabled = False" so I can't do anything...I must kill process in task manager. Same thing happens when I open some other application and then come back to my application.
Can someone tell me how to determine if an account is disabled in AD using VB.net 2008? I've looked at the "userAccountControl" property and this one seems to have it's flags changed when the account gets disabled.[code]I can't seem to figure out the proper statement to determine if the account is disabled or not. It doesn't seem to work out the same way as the lockout status.[code]
If I have two buttons, one to start a song being played and one to stop it. The start button has enabled set to true and the stop button is enabled to false. What I want to happen is the stop button to only become active when the start button is pressed. I was thinking of putting stopMusicButton.enabled(True) within the start method, but this doesnt seem to work

What is the simplest way of enabling the button, when an item in the CheckedListBox is selected or unselected?

When All them are checked I want Button1 to be enabled.And if any Checkboxes get unchecked after they where checked I want button1 to be disabled.
Now I think I got the code right. I just don't know what event to put it under. If checkbox1.checked = true and If checkbox2.checked = true and If checkbox3.checked = true and If checkbox4.checked = true and If checkbox5.checked = true then Button1.enabled end if

I'm disabling a button in vb.net and when I do, I cannot control the BackColor or ForeColor properties to change the appearance. I set new values for them but they don't get picked up. The disabled button looks almost exactly like my enabled buttons so you can't tell the difference. I'm using Flat Style buttons, but have tried changing this and it still doesn't seem to work. Is there some sort of trick to be able to do this?
