HttpRequest and Submit button in html

25-Jul-08 9:04

I don't think there is one. However, a string is really a null terminated character array + it has a ToCharArray method. As the previous poster said there's also the string builder if you need it.

Another alternative is to use a List<char>

Hi,

I'm trying to run a ccxml, and consequently, a voiceXML page externally from the server (like through my application) and the documentation of the server mention that it can be done using HTTP POST.

Following is a simple example of html that works and successfully starts a call on a remote destination

<html>
	<body>
		<form method="post" action="http://localhost:4045/basichttp" enctype="application/x-www-form-urlencoded">
			ID="Form1">
			name: <input type="text" name="name" size="40" value="OutBoundCallEvent" id="Text1" />
			<br />
			URI to be contacted by the outbound: <input type="text" name="ToBeContacted_URI" size="52" value="10.2.50.42" id="Text5" />
			<br />
			VoiceXML URI: <input type="text" name="VoiceXML_URI" size="73" value="file:///C:/voiceXML/three.vxml">
				ID="Text6" />
			<br />
			CCXML URI: <input type="text" name="uri" size="75" value="file:///C:/CCXML/outboundcall.ccxml">
				ID="Text7" />
			<br />
			<input type="submit" id="Submit1" name="Submit1">
		</input></input></input></form>
	</body>
</html>

But I want to achieve the same effect through my c# application and I am using HttpRequest and HttpResponse to mimic submitting the form above.

following is my attempt on this

string uri = @"http://localhost:4045/basichttp";
string data = @"name=OutBoundCallEvent&ToBeContacted_URI=10.2.50.42&VoiceXML_URI=file:///C:/voiceXML/three.vxml&uri=file:///C:/CCXML/outboundcall.ccxml";
byte [] bytes = System.Text.Encoding.ASCII.GetBytes(data);

HttpWebRequest req = (HttpWebRequest) WebRequest.Create(uri);
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
req.ContentLength = bytes.Length;

System.IO.Stream os = req.GetRequestStream();
os.Write (bytes, 0, bytes.Length);
os.Close();

HttpWebResponse resp = (HttpWebResponse) req.GetResponse();
if (resp== null)
{
    MessageBox.Show("Problem in sending response!");
}


System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream());
string result = sr.ReadToEnd().Trim();
MessageBox.Show("All done!");

Now when I try to get the response using HttpResponse I get an error " The remote server returned an error: (400) Bad Request."

Q1 Does writing the data into the stream means the server has send the data just like pressing the submit button? or does the using the gerResponse method this happens?
Q2 Is there something im missing in order to achieve a simple submit function? I have tried sending some data over to an asp page and use response like above and it all seems to work fine.

Any help will be greatly appreciated.
Kind Regards
Fahd

I found out the problem I am not sending the data string in the proper format it requires escape characters for slashes etc!!!

Btw just to share I was advised to use a tool called Fiddler to examine the data sent to the server which in turn lead me to find out my mistake. Seems to be a pretty neat tool.

So you haven't written it then.

Webservices have to be hosted in a web server - there is a clue in the name

It looks to me like you want someone to do your homework.

Hi,

I have a form with a status bar that I want to be maximized whenever it is shown.
I don't want the form to have maximize or minimize buttons so I have set MaximizeBox and MinimizeBox to false. But whenever the form is shown it totally overlaps the taskbar effectively making it invisible.

I have played around with various combinations of FormBorderStyle and MaximizeBox/MinimiszBox/ControlBox settings to no avail.

The code below is enough to reproduce the problem I am having.

Any ideas how to achieve what I'm looking for.

Thanks,

dlarkin77

public class FormTest : Form {
        private StatusStrip statusStrip1;
        private System.ComponentModel.IContainer components = null;

        protected override void Dispose(bool disposing) {
            if (disposing && (components != null)) {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows Form Designer generated code

        private void InitializeComponent() {
            this.statusStrip1 = new System.Windows.Forms.StatusStrip();
            this.SuspendLayout();
            // 
            // statusStrip1
            // 
            this.statusStrip1.Location = new System.Drawing.Point(0, 395);
            this.statusStrip1.Name = "statusStrip1";
            this.statusStrip1.Size = new System.Drawing.Size(643, 22);
            this.statusStrip1.SizingGrip = false;
            this.statusStrip1.TabIndex = 1;
            this.statusStrip1.Text = "statusStrip1";
            // 
            // FormTest
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(643, 417);
            this.Controls.Add(this.statusStrip1);
            this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
            this.MaximizeBox = false;
            this.MinimizeBox = false;
            this.Name = "FormTest";
            this.Text = "FormTest";
            this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
            this.ResumeLayout(false);
            this.PerformLayout();

        }

        #endregion


        public FormTest() {
            InitializeComponent();
        }
}

forget about the maximized start up state and set the size of the form manually (and the location).

this.Location = new Point(0, 0);
this.Size = Screen.PrimaryScreen.WorkingArea.Size;

Not sure if you can do this in the designer - if not, put it in the constructor after the InitializeComponent call. You'll need to set the StartPosition to Manual.

Taking order with PDA

I'm not sure if this is the correct place to ask this question. Sorry if I post in the wrong forum. I have created a POS system for restaurant using C# express and SQL Server express. I want to extend the application, so my client can take orders with PDA. I have think some ways, creating mobile application with C# or create an ASP.NET, or maybe PHP application accessing SqlServer. I am not familiar with PHP but not ASP.NET. So what do you suggest I should be using? Is it posible using C# express creating mobile app? If I should create mobile app, where should I start. Thanks.

I'm not entirely sure, but I don't think the license for C# Express permits you to sell software you create with it. I think it's more of a learning tool. If you can, then I'm happy because I've been working under a complete misconception. If you want to create mobile Apps, I believe SharpDevelop will let you do that, I think they've brought that piece of software along quite a bit.

I personally would go the route of creating a mobile app, but that way you're going to have to write client/server software to interface with your POS database. Going the webserver route, all your code is server-side, you just interface with the database on the server side and your handheld just has a webpage open. Designing a webpage that will work well on the handheld will be a bit tricky, and you'll also need to lock down wireless quite tightly.

You can use the Express editions for commercial use. I raised the same point with someone else a while ago (can't find the thread now!), but I researched it a little and had to correct myself!
