Problem with MdiParent when using command pattern

Hi I have a strange problem.
There's a MdiForm that has a menu item on its main menu.
Here's its click event handler

<br />
private void ShowMyForm(object sender,EventArgs e)<br />
{<br />
MyForm frm=new MyForm();<br />
frm.MdiParent=this;<br />
frm.Show();<br />
}<br />

and it's working fine.
But when I want to replace this code with a command pattern , MyForm won't be added as a child of main form
Here's what I did:

<br />
public class ShowMyFormCommand:ICommand<br />
{<br />
Form mdiParent;<br />
public ShowMyFormCommand(Form mdiParent)<br />
{<br />
this.mdiParent=mdiParent;<br />
}<br />
public void Do()<br />
{<br />
MyForm frm=new MyForm();<br />
frm.MdiParent=this.mdiParent;<br />
frm.Show();<br />
}<br />
}<br />

then I replaced the code in event handler with this

<br />
private void ShowMyForm(object sender,EventArgs e)<br />
{<br />
new ShowMyFormCommand(this).Do();<br />
}<br />

Can you tell me what's wrong ?

Thanks

Hello

Maybe I wasn't following the code correctly but in this line:

this.mdiParent=mdiParent

If the class ShowMyFormCommand is a memebr class of your form then this keyword will reference to your main form. Your main form doesn't have a MDIParent and thats why it should be null. So in the Do method

frm.MdiParent=this.mdiParent;

Your new form doesn't get an MDIParent because this.MDIParent should be null. Try to debug through the code to see if it's null or not.

Regards

Hi all,

Would someone please show me an example of how to use the post request in c#. I want to run a URL but when i use the following...

string Argu = "http://sms.co.za:5567/eapi/sub/send_sms/2/2.0?username=Whatever&password=BlahBlah&message=" + Convert.ToString(Message) + "&msisdn=" + Convert.ToString(CellNo);<br />
			HttpWebRequest Request;<br />
			StreamReader ResponseReader;<br />
			Request = ((HttpWebRequest)(WebRequest.Create(Argu)));<br />
			ResponseReader = new StreamReader(Request.GetResponse().GetResponseStream());

i get an error that says that the URI is to long...

Then i went to look for anything like this on the sms providers help files... i found this: "Please remember to URL-encode all parameters passed! Don't reinvent the wheel - rather use one of the countless libraries available. GET requests are allowed, but we strongly recommend using POST requests, especially if submitting a message to a large number of recipients (there can be limits on the size of GET requests)."

What does this mean...?
How do i use the POST request to run my variable that contains the URL: "Argu" without getting the error of the uri being too long.

Please help.
Thank you in advance...

Basically, you create a web request with just the URL (no variables)

string Argu = "http://sms.co.za:5567/eapi/sub/send_sms/2/2.0"<br />
HttpWebRequest Request = ((HttpWebRequest)(WebRequest.Create(Argu)));

You tell it to use post

Request.Method = "POST";

Then you add each of your variables as header items

Request.Headers.Add("username","whatever");<br />
Request.Headers.Add("password","blah");<br />
Request.Headers.Add("message","hello world");<br />
// etc

Thats all typed by hand, so there might be some mistakes - should give you the idea though.

Would this:

Salon.Library.SystemDefault sysdef = new SystemDefault();<br />
			sysdef.LoadData();<br />
			ASCIIEncoding encoding = new ASCIIEncoding();<br />
			string postData = "username=Whatever&password=BlahBlah&source_id=" + Convert.ToString(sysdef.ID) + "&message=" + Message + "&msisdn=" + CellNo;<br />
            byte[] data = encoding.GetBytes(postData);<br />
<br />
			//Prepare Web Request...<br />
			HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://bulksms.2way.co.za:5567/eapi/submission/send_sms/2/2.0?");<br />
			myRequest.Method = "POST";<br />
			myRequest.ContentType = "application/x-www-form-urlencoded";<br />
			myRequest.ContentLength = data.Length;<br />
			Stream newStream = myRequest.GetRequestStream();<br />
<br />
			//Send the Data<br />
			newStream.Write(data,0,data.Length);<br />
			newStream.Close();

Am i doing this correctly? I saw this in an example on the net...

is this the same as the top part but the top part is the post part?

string Argu = "http://bulksms.2way.co.za:5567/eapi/submission/send_sms/2/2.0?username=Whatever&password=BlahBlah&source_id=" + Convert.ToString(sysdef.ID) +"&message=" + Convert.ToString(Message) + "&msisdn=" + Convert.ToString(CellNo);<br />
			HttpWebRequest Request;<br />
			StreamReader ResponseReader;<br />
			Request = ((HttpWebRequest)(WebRequest.Create(Argu)));<br />
			ResponseReader = new StreamReader(Request.GetResponse().GetResponseStream());

Thank you in advance...

Okay i got it to work with this code...

Salon.Library.SystemDefault sysdef = new SystemDefault();<br />
sysdef.LoadData();<br />
ASCIIEncoding encoding = new ASCIIEncoding();<br />
string postData = "username=Whatever&password=BlahBlah&source_id=" + Convert.ToString(sysdef.ID) + "&message=" + Message + "&msisdn=" + CellNo;<br />
byte[] data = encoding.GetBytes(postData);<br />
<br />
//Prepare Web Request...<br />
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://bulksms.2way.co.za:5567/eapi/submission/send_sms/2/2.0?");<br />
myRequest.Method = "POST";<br />
myRequest.ContentType = "application/x-www-form-urlencoded";<br />
myRequest.ContentLength = data.Length;<br />
Stream newStream = myRequest.GetRequestStream();<br />
<br />
//Send the Data<br />
newStream.Write(data,0,data.Length);<br />
newStream.Close();

But how do i know when an error occurs with this example...
Will this allow me to use more than 2083 caracters in the uri or will it give me an error like with the previous attempt to send the uri request with the get and not the POST. How can i test this, this method does not bring back errors...

Good morning to all. Could anyone please tell me how to syncronize two richtextbox scroll positions? I'm now already on dangerous caffiene levels and running out of ideas.

I'm overriding WndProc to catch the Scroll event and I'm using GetScrollInfo() to
return position data and-so-forth but I'm having no luck with setting or syncronizing the two richtextboxe scrollbars. Please help.

An example that i got of the net shows me how to move the scrollbar up and down but not ultimately to a specific position.

Regards and many thanx

You can change the caret position in the second RichTextBox accroding to the first scrollposition, then use RichTextBox.ScrollToCaret() method to scroll accrodingly.

Resource files are Xml files, so you could use XmlTextReader or XmlDocument types.
If you want to access the information without dealing with Xml take a look at the ResourceManager class.

Hello

You'd have to inherit your own class from class Label, and in your class call

SetStyle(ControlStyles.SupportTransparentBackColor, true);

Then change the BackColor as you like.
