You must either change your system colors (applies to all applications) or owner-draw your entire main form and paint a different fill color in the area occupied by the menu. The MainMenu is not a control and cannot be drawn individually.

Could you give me a little hint on how to do the Owner Draw on the form and fill in different color for the whole Menu Bar area?
|

See the Control.OnPaint method documentation in the .NET Framework SDK. Override this in your form. If you don't know how to perform owner drawing, then you better do a search here on CodeProject. It's not trivial.

Hi!
I'm having a problem whit my page. I have a sql db, and I want to combine to columns, "lastname" and "firstname", from my "user" table. I want to put the the combined two colums in one dropdownlist. This is my sql query:
SELECT DISTINCT u.UserID, Firstname, Lastname
FROM [User] u, Course_User cu
WHERE cu.UserID=u.UserID
Does anyone have a suggestion on how i can solve this?
|

You could change the query so it returns the combined first and last names.
SELECT DISTINCT u.UserID, Firstname + ' ' + Lastname
FROM [User] u, Course_User cu
WHERE cu.UserID=u.UserID
If I had a better memory I would remember more.

I was going to suggest the very same thing that Suzanne did as this is a quick work around.  I have also used an ArrayList to help display the two db columns of data.
Great article suggested by Heath!

Thanks Suzanne!
It worked great!

What Suzanne said is a good idea. If you want columnar data, however, take a look at Multi-Column ComboBox[^] here on CP. It should give you some ideas and seems to already be data-bindable.

Hi,
I'd like to write a simple program that starts by itself when the computers is starting, without user intervention.
How can I do that ?
Thanks
|
|
|
|
|
You can just drop the program in your startup folder if your running windows.
C:\Documents and Settings\user\Start Menu\Programs is a typical location of the startup folder.
|
|
|
|

Yes, that's an idea; but it's not what I expected.
In fact, I want to write an underground program, running like an anti-virus or an alarm. Suppose, to make simple, that it is an alarm.
When the computer is turning on, the alarm-program is starting (undergroundly). And each hour, it makes a sound (with no interface).
How can I do that. Must I build a Windows service ?
Thanks

That would be your best bet. Unless you want to start your program from the Run key in the Registry and set your forms ShowInTaskBar property to false.

It's not funny 
I would prefer you answer my question !

You'll have to create a windows service. If you're using VS.NET you can create a new project by selecting Windows Service to get you started. You'll need to add your code to the OnStart and OnStop methods in the class it creates for you. From the design view of the class right click and select Add Installer. This makes it possible to use installutil.exe to install the service on the target machine. Read about Windows Service Applications[^] for more information.

I've just copied the sample DataGridTimePickerColumn style from the VS help, and used it on a few DateTime columns in a DataGrid (in the constructor, I set it to the short date format). What a mess! You'd have to pay people a lot of money to make them use it!!
Pressing 'Tab' seems to move across the columns as expected, until after you click on one of the columns to give it focus. Then 'Tab' takes you to every other column! Plus if the DateTimePicker is on a form, you can use the up and down arrow keys to scroll the parts of the (short) date. In the DataGrid, all they do is move up and down the columns of the grid.
Has anyone seen an example anywhere showing how to do this properly?

The keyword is example. There are several implementations of various DataGridColumnStyle derivates here on CodeProject and on MSDN[^], but you could always read the documentation and create your own.
The arrow keys are intepreted differently because of the control being hosted in the DataGrid. It's not so easy to make these behave as you'd expect for the hosted control - in this case a DateTimePicker.

hi
i want to know that there is three loops for matrix multipltication for instance
for(i=0;i<3;i++)
{
for (j=0;j<3;j++)
{
for(k=0;k<3;k++)
know if i want to know abt how i should enter the value in an array and what is the function of theird loop how should i input the value in array
3*3d matrix

If you're declaring a multi-dimensional array (as opposed to a jagged array), then you could do something like this:
double[,,] matrix = new double[3,3,3];
for (int i = 0; i < 3; i++)
for (int j = 0; j < 3; j++)
for (int k = 0; k < 3; k++)
matrix[i, j, k] = i * j * k; A jagged array wouldn't be a whole lot different, but you'd declare it as double[][][] and reference elements as matrix[i][j][k]. A multi-dimensional array is recommended in this case. You can read more information about the difference by reading about Arrays[^] in the C# Language Specification.

hi
i try to send xml bitween client and server win app
but
i want to do that as xml not by encoding it into byte`s
thank you
|
|
|
|

You must. All web servers do it, whether download HTML web pages or sending and receiving SOAP messages. You must encode it (whether you do it or some class you use does it, like an HttpWebClientProtocol used for web service proxies or a simple HttpWebRequest) and use the same encoding on both the client and server.
Once the server decodes it using the correct encoding, you've got your XML back. This is how a network works - you upload/download bytes and text gets encoded in order to be send as bytes. Most often, APIs do this for you, but it still gets done. If you insist on using socket connections and sending data yourself instead of using one of the many helper classes, then you are responsible for encoding and decoding data.

Hi,
How can I drawing on axhost control?
I try this code: (AxHost Control is a)
Graphics g = a.CreateGraphics();
Pen p = new Pen(Color.Blue,2);
g.DrawLine(p,0,0,100,100);
but line dont appear. Thanks.

An AxHost control is just the base class for a hosted ActiveX control. The ActiveX control is responsible for it's own drawing, so using a Graphics object to draw on top of it won't work unless you provide some way through your controls supported interfaces to draw on it. One such way would be to return an HDC (as an IntPtr in managed code) from some method in your ActiveX control that you can use to create a Graphics object (see Graphics.FromHdc) and then draw on the ActiveX control.
Also, be sure to call Dispose on your Graphics object to free native resources that the Graphics object uses, otherwise your performance will degrade over time.
