Have you checked the location, size, name and visible properties of this control ? Perhaps they need to be set in order for this control to appear on the form ? i.e. perhaps it's there but not visible, or not in the visible area.

I have testPage.Anchor = (AnchorStyles.Left | AnchorStyles.Top); and testPage.Visible = true; properties set, but it's still not showing anything on the TabPage.
Any ideas?
Thanks.

Not off the top of my head. Have you checked that the control is in the controls collection, and what it's properties are ? What if you add the control to the tab page manually, or add it to another form ?

I just did a test to see if the control was being added to the TabPage controls collection, but it doesn't appear as though it's being added because the returned controls collection is empty. Here's all the code I'm using (it's in the OnLoad event of my Form, I don't know if that makes a difference)
private void PdsPad_Load (object sender, EventArgs e)
{
PdsPage testPage = new PdsPage (DateTime.Now);
testPage.Anchor = (AnchorStyles.Left | AnchorStyles.Top);
testPage.Visible = true;
PdsContainer.TabPages.Add ("Page1", testPage.Title);
PdsContainer.TabPages[0].Controls.Add (testPage);
Control[] ctrls = PdsContainer.TabPages[0].Controls.Find ("PdsPage", true);
foreach (Control ctrl in ctrls)
{
MessageBox.Show (ctrl.ToString ());
}
Form testForm = new Form ();
testForm.Controls.Add (testPage);
testForm.Show ();
}It's not being added to the testForm either. Do you see anything that's amiss?
Thanks for taking the time to help me on this.

What if you drop the 'find' ? I reckon this won't work because the name of your control isn't set.

That worked and the MessageBox now displays PdsPad.PdsPage so it's getting added to the TabPage's control collection. I also thought the problem might be that I was declaring the PdsPage inside the OnLoad handler so when it returned it was going out of scope, but I moved it into the class as a member variable and it still doesn't show anything. Any ideas?
I appreciate all this help you're giving me.

You don't need the member variable, it's kept in scope because it's part of a collection that is in scope.
Once you can see it in the collection, check it's position and it's size ( and double check that it's still visible ). If that doesn't help, I'm not sure.

First, thanks very much for all your help on the issue.
Second, I finally figured out the problem and it's basically that I'm an idiot. I added a couple of extra constructors to the UserControl, but in my infinite stupidity forgot to add the InitializeComponent method to them so none of the controls were actually being created and initialized.
Again, thanks for all your help, if I hadn't been able to confirm (through your help) that the control was actually being added to the TabPage, I would have taken a much longer time to go back and check the UserControl code instead of the code I was using to add it.
Thanks muchly.

Hi guys,
I face the folloing problem and i hope you can help me:
I want to play mp3s on Pocket PC.
I got some src in C++ I recompile them using eVC 4 and tried to access the API to make my app work.
I can't solve the following issues:
1) I make a class to import my DLLs but the CallingConvention has only Winapi option to choose and not Cdecl.
2) The src in C++ is very but written (no comments) and i can't understand what arguments are for.
So,
Does anyone have anything in mind that can help? I read all the articles concerning mp3 but I still can make my App work.
Any link or any tutorial that can help?
Thanks for your time!

Hello,
If I have a class that does some calculations and I want to show the result of those calculations on a form's textbox, how can I do that ?
I have tried writing the following on the class, but it doesn't work:
form1.textbox1.text = showData(initialValues);
Where show data is one of the class' methods and it returns a string.
form1 also shows some other data that doesn't have anything to do with the method showData. showData is invoked by pressing a button on form1.
Thanks.
Regards,
Carlos

Carlos,
Do you have your capitalization correct? Perhaps it should read:
form1.textBox1.Text = showData( initialValues );?
"we must lose precision to make significant statements about complex systems."

There is table with name TableName in first dataset
Id Name Selected
----------------------
1000 Name1 0
1001 Name2 0
1002 Name3 0
There is table with the same name in second dataset
Id Name Selected
----------------------
1000 Name1 1
How can I merge them to get this:
Id Name Selected
----------------------
1000 Name1 1
1001 Name2 0
1002 Name3 0
I prefer to do this by using Merge method, but not with foreach...
|

Where do you get the datasets from? If you fetch them from a database, you can easily merge them in the query. Example:
select Id, Name, Selected from Table1
union
select Id, Name, Selected from Table2
order by Id
---
b { font-weight: normal; }
|
|
|
|
|
u can try to use the ADO dataset merge functin [URDATASET].Merge([URANOTHER DATASET]
i may work and works for me last time
|
|
|
|
|
Merge will only merge tables into the dataset not the actual table.
Calling ImportRow on the target table will do what you want.
You much better off to put this action into a stored procedure get the result into a table.
Your trying to do a set method in an ISAM structure. It wont work.
I'm not an expert yet, but I play one at work. Yeah and here too.

plz
i need to know how to represent (retrieve) the DOM tree of HTML document using C#
please Uegently
|
|
|
|
|
Use Microsoft.mshtml.dll, you can retrieve the DOM tree as mshtml.IHTMLDocument2
Optionally, if you're using .NET 2.0, you can use the System.Windows.Forms.WebBrowser to load an HTML document, then return the DOM tree using System.Windows.Forms.WebBrowser.Document.

To open a new window, using form.ShowDialog()
You can create a Form[] and add eached launched form to that array, sure. Or, use System.Collections.Generic.List<Form> if you want the list to grow as necessary.
If I'm not understanding your problem, you'll need to write your English clearer, as it is difficult to understand.

Hi all,
How can i use system.license library to validate my product license, and what is the standard form for license generator
Thanks
|
|
|
|
|
Which System.License library are you speaking of? AFAIK, there is no such library in the .NET framework class library.

I know its in System.ComponentModel but its my mistak,
Thanks for your reply

There's no License class in the System namespace. There is in the System.ComponentModel namespace, but this is used for DesignTime and Runtime licensing of controls used on forms, not for licensing an entire application.
