your problem(question) is open to multiple understandings  . However, I will assume that you are trying to intercept keyboard event(s) for your application.
If you are trying to intercept the keyboard event for a specific control/form,
you can use the OnKeyDown event
private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
Thread.Sleep(1000);
}
Otherwise, you might want to take a look at Windows Hooks.

Read documentation for SendKeys and Timer Classes.

Use the SendKeys class to send keystrokes or keystroke combinations to the active application.

Hi, I am making a C# application that uses DirectX.
I did not have the DX SDK so i downloaded the "DirectX 9.0 SDK Update - (Summer 2004)"
However, intellisense (in Visual Studio Whitbey) still doesnt show the Microsoft.DirectX API.
What am I doing incorrectly?
thx
|
|
|
|
|
Have you added a reference to the project?
|
|
|
|
|
I tried building a Direct3D application with visual studio .net 2005. It works on my machine, be sure you have installed Managed DirectX and added a reference to the following assemblies:
- Microsoft.DirectX
- Microsoft.DirectX.Direct3D
- Microsoft.DirectX.Direct3DX

Thanks for the help, i didnt know i had to add the references manualy.

Is it possible to select full row in DataGrid instead of cells?
|
|
|
|
|
|
Question is incorrect, I don't want to select full row, I want to disable selecting of single cell,so user must always select full row. Is this possible?
Thanks for any help

Paste the below code in MouseUp. Will solve your purpose.
private void DataGrid1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
System.Drawing.Point pt = new Point(e.X, e.Y);
DataGrid.HitTestInfo hti = DataGrid1.HitTest(pt);
if ( e.Button ==MouseButtons.Left)
{
if(hti.Type == DataGrid.HitTestType.Cell)
{
DataGrid1.CurrentCell = new DataGridCell(hti.Row, hti.Column);
DataGrid1.Select(hti.Row);
}
}
}
Do revert back whether it could solve your purpose or not.
Regards,
Jay.

Thanks alot this works, but now when I click on cell
program first selects whole text in cell,
and then selects full row.
I tryed putting all code in MouseDown, and
"DataGrid.Select(hti.Row)" in MouseUp,
this almost solved the issue but selection is stil visible.
Can I avoid this?

Hi Jack,
I am sorry I could not get your response completely. Will you please ellaborate what do you mean by stating "this almost solved the issue but selection is stil visible.
Can I avoid this? "
Last time when I gave you the code. I had not checked whether it is working properly or not. Today I made a demo application to test the code. It works for me.
I am not sure but please check whether you have changed / modified some of the dataGrid properties like SelectionBackColor , SelectionForeColor etc..
Regards,
Jay.

Hi Jay,
My English is not very well but I'll try to explain:
Code works fine and it solved problem, but when I click somewhere in grid program selects text in that cell like before I entered your code and then it selects complete row (all selection colors are set). So selection doesn't look nice, I was wondering can this be avoided?
Thanks for your time.
Regards,
J.a.c.k

Hi Jack,
I got your problem.
This can be solved by p/invoking LockWindowUpdate.
In MouseDown you lock the window update and in MouseUp you need to unlock it.
Please revert back whether you could do as mentioned above.
Otherwise I will send you the code showing How to do it?
Regards,
Jay.

Thanks Jay it works, just one more question:
How can I select first row of DataGrid in form_load event, if I could simulate click on first row then my mouse_up and mouse_down events would apply on that row. Is there an easy way of doing this?
Regards,
J.a.c.k

Simply call myDataGrid.Select(0), as below:
if(myDataGrid.VisibleRowCount > 0)
{
myDataGrid.Select(0);
}

I can save a date but not a time like 11:01 any ideas, the grid is bound to a wizard generated dataset
Thanks for any help

How do you mean you can't save time? Explain!

Many thanks for your reply
I have a test app with a bound grid a number of columns two are Time
I have a seperate routine which defines the columns of the grid
for the relevant column
DataGridTableStyle ItemList= new DataGridTableStyle();
ItemList.MappingName="TblEventitems";
DataGridTextBoxColumn Col3=new DataGridTextBoxColumn ();
Col3.Headertext="Start";
Col3.MappingName="EIStart";
Col3.Format="HH:mm";
Col3.NullText="00:00";
Col3.Width=50;
Col3.Alignment=HorizontalAlignment.Center;
ItemList.GridColumnStyles.Add(Col3);
DataGrid1.TableStyles.Add(ItemList);
other columns save OK even for the same record but the time remains 00:00 I have tried removing the NullText format
The Date saves OK (which I don't need) but the time is 00:00 If I change the time directly in the table it displays Ok in the grid but then I get a Concurrency Violation if I try to update
