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.
View 4 RepliesI 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.
After I ran a disk-cleanup (in my case AVG PC-TuneUp), the loading of my VB.net project gave error on a missing file.Changing the build-configuration (DEBUG->RELEASE->DEBUG) would recreate the file and all is OK. But I have basic configuration-info for the build, maybe in more complex cases some important details could be lost when the file gets deleted.I would think an information as critical as that, would be placed in the project folder, or be part of one of the many files that make up the project, but not in the temp-folder.
View 7 RepliesPut 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.

View 4 RepliesI'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 am trying to check whether the button is enabled or disabled. I am doing the following

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.

can i use an inverse notation in the databindings to enabled or disabled one checkbox?I have a form that has several controls binded, and if i have true in one field in the database i need to check checkbox and disabled it.Something like:
vb.net
chk.DataBindings.Add("checked", bs, "MyDBFieldBool")
chk.DataBindings.Add("enabled", bs, "MyDBFieldBool")
This can be done directly?
I need to work on my listview. Do you know how I can convert the strings of checked from true to enabled and from false to disabled?

I don't see why this doesn't work. I have gone into the registry and removed the registry key below and still no joy. The error arises at the For Each Loop.

View 4 RepliesMy application uses structures that contain strings and arrays that I want to write to disk. I understand that I can create the fixed length data types in the structures by using "ReDim" and "String$", but my question is: Does VB reallocate the storage for the structure which includes these redimensioned members in-line (which would be necessary in order to write the contents to disk), or does it allocate heap and merely store a pointer in the structure?If only a pointer is provided, is there a straightforward workaround to allow me to create fixed length data types in a structure that could be written to a disk file?Or, Is there an I/O method that will handle the situation by recreating a contiguous buffer containing the structure before writing it to disk?

View 1 RepliesAs some of you are aware of, I am fairly new to VB.NET. I am trying to learn as much as I can. I have a textbox which is set to multiline. It's setup to accept a maximum of 500 characters (10 lines of 50). First of all, since it's size is fixed, how can I remove the right bar on the left as im not using it (the scrolling bar).
#2, once a user click on a button, I disable the textbox and display the text. I can set the background color, however it looks like when the textbox is disabled, text is gray and can't be changed. A fix I found is to use a label and hide the textbox, but are there any easier way ?

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?
