Hi, i've got a little problem when trying to change a datarow caption property.
Lets say that i've :
- one DataTable named dTable;
- the DataTable as 4 DataColumns;
- supose that dTable.Columns[0].ColumnName="CodTerc"
and i do:
dTable.Columns[0].Caption = "Código";
After doing this i expected that my Grid has the first column caption = "Código", but unexpectedly the caption ="CodTerC".
I know that by default datarow caption= datarow columnName, but when i change caption i expect that my grid shows the caption not the ColumnName.
If someone has an answer for this please say something.
Thanks

I have written a C# component that I use in ASP and in ASP I use a
recordset which I would like to give to along as a parameter with a method
from my C# component. How do I handle this ? How can I read that recordset
and what type of variable or object must the parameter be of my c# method.
Any one ?
Thanks
Thomas

I'm currently working on a project which has a registry representation in a treeview in which the user is able to write a path to a key (ex: HKEY_CURRENT_CONFIG\Software) and I'd like to select that registry key based on this string. Is there any way to do this?

Hi, someone knows how can i do so RETURN key acts like TAB key????
I want that if the user presses return key then the application puts the focus on the next component.
Thanks

Hi Carlos
I am not to sure how long your message has been there and I am new to the "reply" function of the code-project.
If you have not resolved the matter- Read on!
I am assuming you are want to use the return/enter key to move from one control to another
A group of textboxes for example? with the "Type in data then press enter" option?
If so, about two years ago I had been racking my brain trying to figure out how to do that then came across the "SelectNextControl" method - from the code-project.
There are five parameters to the "SelectNextControl" method. These are
Ctl
The Control at which to start the search.
forward
true to move forward in the tab order; false to move backward in the tab order.
tabStopOnly
true to ignore the controls with the TabStop property set to false; otherwise, false.
nested
true to include nested (children of child controls) child controls; otherwise, false.
wrap
true to continue searching from the first control in the tab order after the last control has been reached; otherwise, false.
Return Value
true if a control was activated; otherwise, false.
If you are trying to use textboxes then generate two event handlers one for keydown and one for leave
the leave event I use for validating and entering the data into the program.
the keydown is to detect if a key is down (crazy that eh!)
I have several textboxes and the use exactly the same leave and keydown event handlers, in the case below "tbxUpper"
private void tbxUpper_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Return)
{
TextBox tbx = (TextBox)sender;
SelectNextControl(tbx, true, true, true, true);
}
}
the above event actually fires every time a key is presses in a text box but the "if statement" looks for the return key. when the return key is pressed a textbox called tbx is generated and copied from sender then the next control is selected.
If you need furthur help post a reply "and then hit Enter"!!

how can i change/rename an existing regestry key/value (in c/c++ code).

Bwhaahahahahahaaaa - this is great. The first and only question on the C# board is about straight C !!!!
Sorry, I don't mean to laugh at your question, I just find it amusing that it's the first question on the board for C#.
Some pointers for you in future.
1/ Put something meaningful in your header. C ? What does that mean ?
2/ Post to the right board. There is a lively board on C/C++, where you'll find questions answered a lot faster than in this barren place.
There is a registry class or two here at CP which I would expect would do what you want. Just search for registry and see what comes up.

Hi, on my app, i've 2 forms (form1 and form2).
On form2 i've dropped a combobox (named cb1) and declared it has public( public System.Windows.Forms.ComboBox cb1;).
Now, i want to access it from form1 (whit a statment like this one:
Form f2 = new form2();
f2.cb1.size.With = 30;)
, but i do not have access to it...????
What do i need to do to see my form2 combobox from form1, i thought that it would bee enough to declare it public, but looks like i'm wrong...
Thanks

You'll have to make that combobox a property (read-only).

Where can I find a website that has a reference to all the API's in C#? I want all the methods in System.net.*, etc....I want to know what I can call! Like what's in the headers of C/C++, if you're confused. Thanks!

You have two choices:
1) Use MSDN online, at http://msdn.microsoft.com
2) Get VisualStudio.NET, and use MSDN locally.

I've tried to use MeasureString function and noticed that it almost always returns size that is noticeably wider then the actual string. So, I was wondering if any one can comment on this behavior. Is it a bug or a feature  Also, does anybody else thinks that support for text output in .NET SDK is totally inadequate? How is one can change kerning or get character glyph?…
|

Well, MeasureString have been broken in Beta 1 (it returned invalid result for some fonts). They fixed this problem in Beta 2. Still this function might be inadequate for precise measurement. I agree that .NET does not have enough power as far as text output goes (fonts, measurements). E.g. writing fully managed text editor with support for variety of fonts is an uphill battle (I would even say it is impossible). The only solution is to use P-Invoke to call into Windows SDK functions. I suspect that due to the fact that .NET is supposed to be appealing for cross-platform development they couldn't include any "Windows specific" functionality.

Andrei Zenkovitch

Thanks for the info Andrei! I did figure as much myself. Unfortunately I was trying to create text editor with extra features not found in RichEdit and for now I had to abandon it. I hope Microsoft reconsiders their decision about text output support (or lack of it) in .NET. As for Windows SDK, if I have to use it I'd rather use it from C++.
Cheers.
P.S. I am using Beta2 VS.NET

Hi,
I have recently produced some C# tutorials for my company. I was wondering if anybody would look through them and let me know what you think.
The web address for the introduction to the tutorials is http://www.softsteel.co.uk/tutorials/cSharp/cIndex.html
