I was wondering if there was a function in user32 that could enable a hwnd control if it is disabled (grayed out) If I know the handle then can I do this? Also, if it is a menuitem, can it be done too?

Having said these things. I used to program in VC++6, VB6. But using those version now seems not realistic now as I lost touch. But if I have to use the latest 2008 versions, for which I do not have any experience seems scary. So, If you are reading this , and you have got some experience in these fields or using controls that support my requirement, can you please let me know which programming language or IDE and Control should I use to develop this application. PS: the image is made using mspaint and does not represent actual program.
I have a VB windows application and I need a way to control input output from this windows application to a batch file.The batch script is quite complex so converting to a VB console application is out of the question because it will too much time.An simplified example is this:I have this batch file test.bat(just for example)
@echo off
set /p choice=name : %choice%
echo Hello %choice%!
In this batch file the user input the name which is then stored in a variable and after the user press enter on the screen will appear Hello + user input.
1. Is it possible to enter the name in a textbox from the windows form and by pushing a send button pass the name to the batch application and then the batch file to continue the operation of displaying the Hello message?
2. After the batch file finishes the operations it will open another console windows (3) with status of the various operations that take place on the system(in my case connected users to a server)Is it possible to hide this child console windows that are generated after my main .bat application finished the operations of opening connections?Can this be done from the windows application or I need to modify the .bat script?
3. Is there a way to collect the console windows output in a textbox from the windows application?One idea that came to me was to redirect the console output to a textfile and then read the textfile in the VB application but I want to know if there is another way.
4. Is it possible to hide this batch file inside the windows application exe?

3) I marked the sub startup() with STAThread()
I am writing an application that puts a computer in hibernation mode (Application.SetSuspendState). I have noticed that there exists a specific option that needs to be enabled for the machine to hibernate correctly and that is found in Control Panel--> Power Options --> Hibernate Tab (if this option is not checked then the machine goes into stand by mode rather than hibernate) Is there a way to programmatically check the status of the "Enable Hibernation" check box and check/uncheck it?

View 2 RepliesI have an application than disables the screen saver temporarily in order to run a slide show. I use this to turn it on or off:
i = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, active, Nothing, SPIF_SENDWININICHANGE)
This works fine in XP. In Windows 7, it disables the screen saver properly. However, when it is enabled again, at the normal time for the screen saver to come on, the system asks for a password instead of showing the screen saver.From this time on until the screen saver settings are adjusted in the control panel, the password screen is displayed in place of the screen saver.Is there something else I should be doing for Windows 7? I understand that SPI_GETSCREENSAVEACTIVE is not supported in Windows 7, but SPI_SETSCREENSAVEACTIVE is supposed to be.
In my Windows Form's application, I enable and start a Windows Form's Timer for a state machine which interacts with various User Controls. In one part of the state machine where an external device is being rebooted, I need to disable the User Interface (a User Control's UI) for the time it takes the device to reboot. The problem exists in that once I use System.Threading.Sleep, the timer that fires the State Machine stops and never restarts. I even re-enabled the Timer and re-started it after the Sleep command but to no avail. Is this expected operation or should a Windows Form's Timer be able to restart after a Sleep?
Snippet of code from a step in the state machine below:
Cursor.Current = Cursors.WaitCursor
MainForm.Enabled = False
System.Threading.Thread.Sleep(8000)
MainForm.Enabled = True
Cursor.Current = Cursors.Default
MainForm.t1.Enabled = True
MainForm.t1.Start()

View 11 RepliesI moved this from the debugger thread as I got no responses.This may be a better area.I have a problem enabling a Scrollbar on a custom control I have created.The custom control has one component,the scrollbar and an area that I draw upon from an internal datasource.Think something like a textbox.In certain instances,I want the scrollbar to be enabled. The Custom Control's job is to do this when the situtation is appropriate.I have a very simple piece of code here:
If <logic conditions> Then
DataScroll_vscrollbar.Enabled = False
Else[code].....
This code is in my OnPaint routine (along with a bunch of other drawing related stuff).Essentially I've determined that there is more stuff to display than the area of the control and need to turn on the scrollbar to give the user of the control the ability to see later stuff.With the exception of this funny behavior, the control is doing exactly what I want.I step through this and have a watch set.I can step through the set to True, but the Enabled value doesn't change.Even the EnabledChanged event fires (Doesn't on the set to False because it's already False), but the Enabled value is still False.I don't know why.Now here is the really interesting part and may give somebody an idea about what's happening: I can change the Enabled value via the debugger (via the Watch) to True.The EventChanged will fire, and from that point on I can set the Enabled value to either True or False and back again with no problems.
I even did some really crazy testing to see if perhaps the debugger just wasn't showing something.
did something like:
Dim idiot as boolean = false
if <logic> then
idiot = true[code]....
I have set the values to Minimum and Maximum, but the problem remains.
I have a RichText control on my form. In the control when running, the tab key does not do anything. I would like to enable it and set the size of the tab. How can I do this?
View 1 RepliesI'm trying to enable the screensaver from within my application I found this code on the internet:
Declare Auto Function SendMessage Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal Msg As UInt32, ByVal wParam As UInt32, ByVal lParam As UInt32) As Int32
Const WM_SYSCOMMAND As UInt32 = &h212

But it's giving me an error "Expression expected" on the three Const lines right at the & character.
this is probably pretty simple, but I've noticed that when trying to start the Windows Media Player (AxWMPLib), it takes the "player.url = path", and only then does the player's Play-button get activated. Thing is, I want to play sound files taken from the URL of a column in a database. And when clicking on that row, the mediaplayer should update, making it's play-button clickable.
