Project->Add Reference...

Select Microsoft.DirectX and any useful component parts (eg. Microsoft.DirectX.DirectDraw).

At the risk of sounding ignorant, have you searched the COM tab in the Add Reference dialog?

yes. I did search on the COM tab, only have directX for VB, not DirectX for c#. The more strange thing is after I downloaded and installed SDK9.0 for C#, all the api are c++.the label of downloaded component is C#,but why the code and API of that is c++?
do u have any idea?
thanks a lot

If you want your project to be able to access "Managed DirectX", then you'll have to search for Microsoft.DirectX.< DirectX Component > under the .NET tab.

Those libraries under the COM tab are for Visual Basic 6, but you can use them with VB.NET or C# ( both VB.NET and C# both would require an Interop dll which would be created by visual studio once you add the reference )

Unfortunatly, 95% of the documentation you download from Microsoft for DirectX will be in c++, but if you search hard enough you will find some VB documentation inside the C++ help files (especially for DirectShow). On the plus side, the directx objects for C++ and VB are similar and work basically the same way. The C# code is in the SDK directory in the samples folder.

Hope that's of some help to you.

In you project you have created two forms.

Form1 -- this is your MDIParent form
Form2 -- your child base form.

In the properties for Form2, find the Layout / Window State property and change if from Normal to Maximize.

Rebuild your project and your children will now be maximized.

DataGrid Heading Display

In my program, I used a DataGrid to display the data from the database. I realized that the column headings are in alphabetical order from left to right, which is not what I want. How can I change the setting to display the columns in my own way? I've tried using the TableMappings property of DataAdapter, but I couldn't make it work. Please give me some instructions about it. Thank you!

You can use the DataGrid TableStyles.
First you add one GridColumnStyle and a collection of columns to it. Each column you set the 'mapping' value to match the column in ur dataset that u want to display .

Scrolling records from Access

I am teaching my self C# and the book I have doesn't show how to scroll to the next record. The standard thing I do is to move to the next/prev record check for eof/bof and if that is true, move to first/last then display the record. I can't find how to move to the next/last/prev/first record. I can think of a way using a global variable and tracking the recordcount and check the location, but the way I mention is easier. Can anyone point me to the MSDN page, or other page that gives a nice example of this? Thanks

Are you working with either a DataReader object or a DataSet object? If not, then check out these objects before you go any further.

I'm working with a dataset object.

Mark Sanders11-Mar-03 12:16

Because a dataset is a fully disconnected container for data, datasets (unlike ADO recordsets) do not need or support the concept of a current record. Instead, all records in the dataset are available.

A dataset can be made up of multiple DataTable objects which in turn can have DataRow objects and DataColumn objects. You can use a variety of different means to access these objects such as foreach loops or direct minipulation.

So if there is no methods to a the standard first/prev/next/last, would I need to write my own routines to do such things? Or is there another datatype that I can use have access to this?
This makes scrolling though database records one at a time quite a bit more difficult then I think it should be with a new language.
Or perhaps someone has made such routines I can thiev and use.
Thanks

There are two ways: you can use notation
this.dataSet1.Tables[0].Rows[i] to point the row you are looking for, or you can play with CurrencyManager. CurrencyManager is much more powerful, and probably this is the routine you need.
link to CurrencyManager Class specs (MSDN):

Hi,

I have very strange problem!
I am deriving my own class, inherited from TabControl.
I need to make my own painting, so I wrote that:

SetStyle(ControlStyles.AllPaintingInWmPaint, true);
SetStyle(ControlStyles.UserPaint, true);
SetStyle(ControlStyles.DoubleBuffer, true);

Then proccessing the OnPaint method worked just fine, but when I decided to handle the scrolling of the tab pages I found out that I CAN'T get rid of the two scroll buttons windows draws on the tab control. I overrode almost every possible virtual method and put "Invalidate" in it, but the scroll buttons still appear Frown | :(

Any idea of how scrolling the pages on my own, without the help of windows?

protected override CreateParams CreateParams

   get
   {
      System.Windows.Forms.CreateParams param = base.CreateParams;
      //we need to prevent to control calling the vscroll or hscroll
      if (((int)WindowStyles.VSCROLL & param.Style) != 0)
      {
         param.Style -= (int)WindowStyles.VSCROLL;
      }
      if (((int)WindowStyles.HSCROLL & param.Style) != 0)
      {
         param.Style -= (int)WindowStyles.HSCROLL;
      }
      return param;
   }
}

This I used for the RichTextBox, should work for a tabcontrol as well.

Your code should work for ONE CONTROL, but the case here is not that:

I finally found out what is wrong with MyTab Smile | :)

As it wrappers the common controls TabControl when scrolling of the tab pages is needed
a new updown control is created that has nothing to do with the parent TabControl and thus it receives no messages through its parent

Now my question is do you have any idea of how to get to that updown control and prevent it from displaying?
