Are the speakers plugged in? That is plugged into the computer and plugged into a power source?
Is your volumn turned off?
Those would be my best guesses.

Better yet, plugged into the correct port?

If the speakers are all plugged in correctly, you might want to try unplugging them completely from everything and plugging them back in. I have a problem with my speakers where it seems some static builds up and they dont work until I unplug the power adapter and and speaker to computer plug and plug them back in.
Also check for driver updates, it may be that the mouse change is interfering with the speakers.
Check for IRQ conflicts.

Hi all,
I need to be able to automatically run a program of my choice, say an .exe or a VC++ program, when a particular USB device is plugged in. Does anyone know how to do it, or know where i can find more information about this topic?
any help is greatly appreciated!
thanks and regards,

I think you are using Windows environment. Assuming the same, this is how Windows OS works.
There is a service called Plug And Play (see services.msc) and you will see this service as running (generally) on computer systems. This is the service which keeps the track of any device plugged in/out from the PC. Either you create a windows service which checks these ports or you hook your application with system service to get the notification about any device added/removed from the system and accordingly execute the next steps.
Let me know if you need any further help on this.

I have Windows XP Home. I have an external Buffalo hard disk partitioned. When I "safely remove" the drives 2 partitions remain in Explorer and Defrag sees them too.
Other than the icons just being there I think they are messing up my being able to get Microsoft Updates even though I have a genuine Windows copy installed on my 2002
Hewelett Packard Pavilion 762n. Any idea on how to fix this? Thanks

Q. Do you copyright your source code?
It bothers me to have to mail my secret source code to a copyright attorney or U.S. copyright office. I'm not comfortable with anyone seeing all my hard work. Who can you trust?
I'm asking because it seems to me very difficult to prove or disprove if my source code is being used, whole or in part, by another program.
A software thief would be smart enough to not copy a Windows App in its entirety because it would look identical to the original.
However, a small DLL copy or clone and rename would probably pass the public eye unnoticably.
I fully understand book copyrighting because the text is public and easily compared to another authors text. Plagiarism much more easily detected and proved or disproved.
But software source code is something hidden from public eye.
There's no way I could know if someone has cut-n-paste my source code into thiers.
On the other hand, I can also understand that copyrighting may be a good 'extra care measure' to protect the 'what if' cases of source code theft.
Q. What is your honest opinion about source code copyrights.

As far as I know, anything written or produced by an individual is copyrighted in the United States regardless. The officialness of all of that would be Trademarks and Patents and those must be taken care of through official means.
Having said that, I agree that it would be difficult to prove anything along those lines, Im really not sure what to tell you about how to protect everything.

How to add controls such as checkbox, textbox, optionbutton to datagrid in windows application?

Hi,
I am creating a Windows Installer wherein I have added a "RegisterUser" dialog to the installer interface.
However, I would like this "RegisterUser" dialog only when it is being freshly installed on a machine.
For eg. If I am installing the software on machine A for the first time, then RegisterUser dialog will be displayed on the screen. After that if i uninstall the software from that machine and again re-install the same , then the "RegisterUser" dialog should not be displayed again, since the software was already previously installed on that machine(A)
Please Help!!!.
Thanking you in Advance
Kind Regards
Pratik Shah

I would recommend creating your own custom action. Create a new assembly containing your own user registration form and a class derived from System.Configuration.Install.Installer. Handle the AfterInstall event and display your own form:
// MyInstaller is derived from the class 'Installer'.
MyInstaller() : base()
{
AfterInstall += new InstallEventHandler(AfterInstallEventHandler);
}
private void AfterInstallEventHandler(object sender, InstallEventArgs e)
{
// Show the user registration form.
if (NewUser())
new MyUserRegistrationForm().Show();
}
private bool NewUser()
{
// Determine whether this is a clean install.
}

Do you mean to create your own ones rather than using the existing ones? Also I would like to know what programming language you intend to use for these? C or Vb.net.
What a curious mind needs to discover knowledge is noting else than a pin-hole.
|
|
|
|
|
Yes i mean creating new ones. I use C# as a programing language
|
|
|
|
|
Exactly what do you expect us to do for you?
|
|
|
|
|
I would suggest searching on this site and on google for
"Extending ToolBar in C#" etc. you will find many useful things.

I am working on a POS application that needs to run once, and then when called again it will just activate the current instance. So I have the run once code working but now I need to be able to pass params to the running instance. I am trying to implement a way to save the params to my properties.settings.default.param1, so when the exe is called the second time, I check for an existing instance by name, and if I find it I restore it. before I restore it I save the value of my params, and in the activated event of my form, I grab that data and present it to the user. Well this is not working all the time, sometimes it works sometimes it does not...I'm totally open to new ideas on this process...
