Realtime HTML editing

Hi,

I am very new to programming so please be gentle.

I am trying to create a program that will 'build' an Outlook HTML signature. I am working to a strict layout so I will use Text boxes to control line-by-line what users can enter. We also have logos that are served via a URL.

I was hoping to use the "WebBrowser" control to display the HTML. I have found tutorials where they have created an HTML file on the local disk, then displayed it but I was hoping to skip that and display it straight from RAM. After reading about the control, I thought I would be able to write directly to it using WebBrowser.DocumentText = "<html><body>test</body></html>" type format. Unfortunately, my WebBrowser component remains blank. I have also tried a call to the Refresh method but still it did not show anything.

Could anyone tell me where I am going wrong? Also, as a noob, how would you set this up? I have a form with my components on, then created a separate class which holds all of the data entered in private variables, access using public properties. I will also create a method in this form to create and store the HTML string ready for outputting.

I'd really appreciate any help.

Thanks

Solution 1

I would assign a method to the TextChanged event of all text boxes.

This method could look like this

C#

private void textBox_TextChanged(object sender, EventArgs e)
        {
            StringBuilder sb = new StringBuilder();
            sb.Append(textBox1.Text);
            sb.Append(textBox2.Text);
            webBrowser1.DocumentText = sb.ToString();
        }

Ah, great, I was kind of doing your suggestion so I looked a bit harder into the setting on the webBrowser. I found that I had changed a property of the webBrowser which was stopping it working. I had assumed I was not using it properly. It was the property "Allow Navigation" that was set to False. I had previously followed an online tutorial which required it to be set to false. this obviously did not suit what I was trying to do.

Thanks for your help, I was unaware of the "string builder" so you have been a big help. It will tidy my code up loads and my webBrowser control works a treat now thanks again.
