Code Snipset:

xmlCDList->Load(strCDListFileName);<br />
<br />
XmlElement *nodRoot = xmlCDList->DocumentElement;<br />
XmlNodeList *nodCDListCDID = nodRoot->GetElementsByTagName(S"CDID");

The problem is:
nodCDListCDID->Count is always 0 (zero)

Please help. Thanks in advance.

Yes, it appears you have. And I was coming to follow up on another one of your questions, too....

Why use 'GetElementsByTagName' ? I think the 'tagname' is the ID element. Try nodRoot->SelectNodes, with this: "/CDList/CDList/cdid", or this: "//cdid". These are valid xpaths. Why does the CDList node nest a copy of itself ?

Also, XML is case sensitive, if the above code was to work, you'd nee to make "CDID" the same case as in the XML.

Why wouldn't it ? It's correct case.

I'm trying to use resetText () to reset values of some text boxes to their default. I'm using it as follows,

<br />
myTextbox->ResetText ();<br />

but all this seems to be doing is clearing the text instead of resetting defaults.

Any ideas???? Because I'm stuck. Confused | :confused:

Re: TextBox->ResetText () question???

Saksida Bojan20-May-05 9:09

Try Any of these. ResetText it says it will reset Text. Reset functions are listed below.
textBox1->ResetBackColor();
textBox1->ResetBindings();
textBox1->ResetCursor();
textBox1->ResetFont();
textBox1->ResetForeColor();
textBox1->ResetImeMode();
textBox1->ResetText();

if you still haven't found right Function create yourself a function to restore to default.
Example:

void TextBoxResetToDefault(TextBox *txtBox)<br />
{<br />
	txtBox->Text = S"";<br />
	txtBox->Enabled = true;<br />
}

I will not use SendMessage, because it is Win32 and MFC Command, I am using .NET Framework.

Pass form2 a pointer to form1.

If i pass poitner to Form1, Form1 would have access to form2. This is also working without passing a pointer.

If i pass Pointer of Form1 to Form2 As Form member, i can't accsess public function on form1

yes you can :

into your form2, you create a member that is a pointer to a form...

then you allow the constructor of form2 to receive a pointer to a form (form1 for example) that will be copied in its member...

Still i can't do it. Here is snipset from a code. Tell me what am i doing wrong.

Form1:

	private: System::Void Form1_Load(System::Object *  sender, System::EventArgs *  e)<br />
	{<br />
		 Form2 te = new Form2(this);<br />
		 Form2->Show();<br />
	}<br />
public: void test()<br />
	{<br />
		MessageBox::Show(S"Hello from Form1");<br />
	}

Form2:

public: //Constructor<br />
	Form2(Form *test)<br />
	{<br />
		InitializeComponent();<br />
		frmTest = test;<br />
	}<br />
Form *frmTest;

Form2::
i use
frmTest->test();

i got compiling error
c:\Projecti\t3\t33.h(86): error C2039: 'test' : is not a member of 'System::Windows::Forms::Form'

Please help me.

Is your first Form called Form ? Or is Form a base class ? If it's a base class, of course you can only see the base class members.
