Well yes. That is what I would expect - you only have the one "photos" node. You need another loop:
XmlNode root = PropertyDocument.SelectSingleNode("//overseas_sales");
XmlNodeList nodeList = root.SelectNodes("overseas_sale_ad");
ArrayList ElementsList = new ArrayList();
foreach (XmlNode n in nodeList)
{
if (n.SelectSingleNode("external_id").InnerText == ID)
{
XmlNodeList photos = n.SelectNodes("photos");
foreach (XmlNode ph in photos)
{
foreach (XmlNode photo in ph.SelectNodes("photo"))
{
ElementsList.Add(photo.InnerText);
}
}
}
}

Thank you so much, adding another loop solved my problem.

You're welcome!

You need to use SelectNodes to get them, not SelectSingleNode, and I would use one loop:
foreach(XmlNode ph in nodeList.SelectNodes("//overseas_sale_ad[external_id='R214']/photos/photo"))
{
ElementsList.Add(ph.InnerText);
}
Brush up on XPath.
I would also use a List<string> rather than an ArrayList -- no one uses ArrayList anymore.

'System.Xml.XmlNodeList' does not contain a definition for 'SelectNodes' and no extension method 'SelectNodes' accepting a first argument of type 'System.Xml.XmlNodeList' could be found (are you missing a using directive or an assembly reference?)
Thank you for your reply. I am getting this error. But no problem I got my solution

Oh, yeah, you need a node. No biggy. You should still only need one loop.

I am using myform.Activate() to activate MDI Child form and running a code on activation. what is the form already active? is it possible to re-activate so my code will run again on activation?
|

Move the code to it's own method.
You're depending on a simple specific behavior of a form to trigger the exection of code that needs to be triggered under varying circumstances. move the code to it's own method so you can call it from Form.Activate and other events as needed. I have no idea what you're doing or why this code needs to be executed on Activate so it's impossible to suggest something appropriate.
The only way to get Activate to fire again is to make another form active and then make your target form active again. The problem with that is the active form will redraw itself to be on top or your real target form and then the target form will again redraw itself on top of the others, making your form "flash".

I have a page with a few validation controls and a ValidationSummary control. Most of the validation controls are RequiredFieldValidator controls and the summary control displays these messages just fine.
I do have a RegularExpressionValidator that checks for the format of an email address. If the address isn't entered correctly my error message from this control isn't being displayed by my summary control.
I know the problem isn't with my regular expression as I can display the error message by the regex control if I change the Display setting.
ValidationSummary doesn't just work with RequiredFieldValidator does it? That would be less than helpful.
My code :
<asp:ValidationSummary ID="ValidationSummary1" ValidationGroup="Test" HeaderText="You must enter a value in the following fields:"
DisplayMode="BulletList" EnableClientScript="False" runat="server" />
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ValidationGroup="Test" ControlToValidate="txtReqDuration"
ErrorMessage="Enter a valid number" Display="None" ValidationExpression="^([\d]{0,2})$"></asp:RegularExpressionValidator>
Thanks.

You already posted this in the ASP.NET forum; please do not multi-post the same issue.
One of these days I'm going to think of a really clever signature.

i put this code in textbox_textchanged and textbox_editvaluechanged, both didn't work.
yes i'm new in C#, but i think this is so simple.
is this a problem in threading
string uppercase = this.txtLicense.Text.ToUpper();
this.txtLicense.Text = uppercase;
i'm not sure i need to create a new thread just to force a textbox uppercase.

No it is not a problem with threading unless you did not reveal all of the information.

"didn't work" does not tell us anything about the problem that you are having. You should know this by now.

You need to use LostFocus event to do the same.

well, thank you very much for trying.
i realize it's not that hard to answer this,
character casing properties fix my problem. 
modify :
"i'm not sure i need to create a new thread just to force a textbox uppercase."
thank you for the reply, but i'm sure you understand it.
don't worry, next time i will write it more detail.

What does this line do, besides the obvious things? Well, it sets the value of a textbox.
..which means that the value has changed. If the value changes, the Framework will trigger the "textbox_textchanged" event. So, we execute that code - which tells us to change the value again. (See a pattern?)

After the second bounce the value will not change so the event shouldn't fire forever.

Does the setter of the text-property of the textbox include a check to see whether the value is the same, or not?

It should, at least for the TextChanged event (the clue's in the name!), but I haven't actually tested it right now.

The times that I programmed against a intID where the clue in the name was erroneous..
You are right, I decompiled the TextBox, which points to TextBoxBase, which has this in the setter implementation;
this.has_been_focused = false;
if (value == this.Text)
{
return;
}
(Śtill untested)

Probably a bit late now, but the normal way to do this is to intercept the character before it makes it into textbox rather than trying to alter it once its there.
To do this, you want to intercept the WM_CHAR message (either by hooking the event KeyPress at form level of overriding a virtual OnKeyPress(Or similiar?) in a class deriving from TextBox. Then check the character and if its in the range a-z alter it to be A-Z (By subtracting 32 simplest way if ASCII).
edit: That is of course assuming this is Winforms, an assumption I may have jumped on too soon as Bob mentions above.

Hi Friends,
I am trying to create a new thread to make the picturebox is visible (to show Loading icon) when the ConvertFiles method is running, but it is not successful (Please see below codes)
Do you know what's wrong ?
private void ShowLoadingIcon()
{
if (InvokeRequired)
{
this.Invoke (new MethodInvoker( ShowLoadingIcon));
}
else
{
pixLoadingIcon.Visible = true;
}
}
private void btnConvert_Click(object sender, EventArgs e)
{
Thread thLoading = new Thread(ShowLoadingIcon);
thLoading.Start();
ConvertFiles(sourceFile, destinationFile);
}
Thanks and regards,
|

What does this mean? The thread does not start? The thread starts but does not do anything? The code runs and your cat died? "it's not successful" does not tell us anything about what your problem is. Did you run it through a debugger? What did you discover?

I think you are doing this backwards. The invoke back to the UI thread will be blocked until your long processing task is finished.
You should actually be trying to do something like this
string sourceFile, destinationFile;
private void ShowLoadingIcon()
{
if (InvokeRequired)
{
this.Invoke(new MethodInvoker(ShowLoadingIcon));
}
else
{
pixLoadingIcon.Visible = true;
}
}
private void btnConvert_Click(object sender, EventArgs e)
{
ShowLoadingIcon();
System.Threading.Thread t = new System.Threading.Thread(() =>
{
ConvertFiles(sourceFile, destinationFile);
});
t.Start();
}
private void ConvertFiles(string src, string dest)
{
}

Great ! It is successful now.
Thanks Trak4Net very much.
