Stop ClickOnce Publishing

I have a solution with two executable projects, and two libraries. One exe is private, for support only, and the other is to be deployed as ClickOnce to clients. However, when I publish this app with the wizard, it always publishes the other app as well, even if remove that app from the build. If create a third project, an exact copy of the support project, it does not publish. This indicates that the project name is persisting somewhere when it should not. Any ideas?

On the properties page for the project look under the Publish tab, click the Application Files button and see if the unwanted app is listed there.

I looked, and it wasn't there, but now it's not publishing. Just one of those things.

However, now it has just arbitrarily stopped installing the Start Menu etc. items, even when the application is clearly marked for on and off line.

I'm going to go to manual publication now.

You can't, that's the whole point of a hash, it's one-way. Although you could get it via brute force.

As of how to accomplish that have you ever tried Google?

Hello Friends,

I want to play a "beep" of perticular sound device.

That is i have more than one sound cards in my PC. But i want

to play beep from sound card from specified card. how to do

sound card selection through coding only.

Currenly, i am using playsound function of winmm.dll but can't

specify sound card in that function.

So, How to do that.

Thanks in advance

First question is why would you need two sound cards? I don't think it will work. I have a system with a built in sound card but when I plugged in a PCI card it disabled the onboard.

Thank you for reply.

I clear my intention.

What is the thing i have made an application which uses

an external sound card i.e. usb sound card.

currently i am using playsound function to play ding of system

But it uses default sound devices i.e. onboard sound card and not

my externally attached one. So i want any other function in which

we can specify sound card to be used to function to select default sound card.

Thanks in advance.

opengl on a windows form

Hi all
Firstly, I'm sorry if this is a stupid question, but I'm new at all thia programming malarkey.
I'm attempting to write an app using C# and at the moment I need a graph display that has several specific functions. Mainly, I wish it to be very interactive, with realtime panning and zooming of the displayed waveform.
I have completed this using GDI+, but it does not seem fast enough. When I pan or zoom the graphical display there is much flickering. Double buffering didn't help.
I've been searching the web for a good few hours now and come up with nothing.

Hence I though opengl was the solution, but I'm having trouble finding a tutorial or information about how to create standard windows form application with buttons and the usual controls and have an opengl view in it. (to clarify, its the opengl window on the form bit I cant find, *not* the windows form standard controls)

So, two questions really:
1. Will using opengl (CsGL, Tao, whatever) actually help? I as assuming it outperforms GDI+, is this assumption correct?
2. Are there any tutorials on how to plonk an opengl window onto a windows form?

Thanks in advance.

Yes, it will outperform GDI+. DirectX is another posibility, it has managed wrappers supported by Microsoft.

Programming DirectX is not trivial (I have no idea how it is with OpenGL) as you have to deal with stupid things like lost devices etc.

If possible timewise (and given the system requirements you can enforce before running your app) consider simply waiting for Windows Presentation Foundation which is in release candidate now.

I've not heard of Windows Presentation Foundation, I'll look that up. I'll also see if there are any tutorials for DirectX.
I think that opengl isn't all that hard. At least not for the relatively simple things that I'm attempting to do (a graph is just a bunch of lines after all)
I did find some tutorial about setting up an opengl window on a form, but I've yet to try and implement it. It also used CsGL as opposed to Tao, which I thought replaced CsGL.
Thanks for your reply and I'll keep plugging away.

Any other tutorials or information people could point me in the direction of would be very helpful.

Maximum URL?

This is the code i'm using....

public void Sender(string BoodSkap, string No)
{
Salon.Library.SystemDefault sysdef = new SystemDefault();
sysdef.LoadData();
string Argu = "http://sms.co.za:5567/submission/send_sms/2/2.0?username=Example&password=Example123+"&message=" + Convert.ToString(BoodSkap) + "&msisdn=" + Convert.ToString(No);
HttpWebRequest Request;
StreamReader ResponseReader;
Request = ((HttpWebRequest)(WebRequest.Create(Argu)));
ResponseReader = new StreamReader(Request.GetResponse().GetResponseStream());
}

I got an error last night that said URL too long could not resolve.
What is the maximum length of a URL?

Thank you in advance...

If the URL could not be resolved then the address you provided does not exist. It is nothing to do with the length of the Url.

As of how to accomplish that have you ever tried Google?

custom messagebox without making instance???

hey all
i'm having trouble creating my own "messagebox" class

problem: i want to be able to display large quantities of text. messagebox.show will not do for this option because i want a scrollable textarea to be used.

what i found: all the methods to do this use a custom form that needs to be instanciated and then one can use the showdialog option. i'm not fond of this way of handling it. i'd rather use a call like

MyMessageBox.Show(title,theverylongtext);

where MyMessageBox is the name of the class of my custom messagbox and no instance of any class.

tnx in advance.

So write a static method called show, which creates an instance of your form, shoves in the text, and shows it.

thanks. this is my code now:

private MessageDialog(string text)
{
	this.textBox1.Text = text;
}

public static void Show(string text){
	new MessageDialog(text).ShowDialog();			
}

i guess i could've made my constructor public and done something like
new MessageDialog(text).ShowDialog() from my main application to call it, but i like it better this way Smile | :)

Remember to call Close on the form once you're done with it (after calling ShowDialog), otherwise you'd be leaking resources.

Thanks in advance!

Your question cannot be answered. Yuor code is overwriting the nodes, or you have some other problem with persistence. We'd have to see the code to know.

this.settings.Encoding = Encoding.Default;

}

public void WriteStartElement()
{
this.writer = XmlWriter.Create("Testing.xml", settings);
this.writer.WriteStartElement("Information");
this.writer.WriteElementString("DateOfBuilding", dateTimeNow.ToShortDateString());
this.writer.WriteElementString("TimeOfBuilding", dateTimeNow.ToLongTimeString());
}

public void WritingToXMLDoc(string elementString, string writeToXMLDoc)
{
this.writer.WriteElementString(elementString, writeToXMLDoc);
