Hello,
Is there a way of changing the captions of MessageBox buttons to something else? Or, if I want different buttons' captions I have to create my own dialog box?
Thank you.

You'll need to create your own dialog box. The MessageBox class is pretty well sealed up and you can't do much with it beyond what it's supposed to do. It shouldn't take more that five minutes to whip up your own dialog box class in Visual Studio anyway.

Is there a tutorial on the different events and their sequence of firing for a typical windows forms form?
I am curious about comparing the event sequences from MFC to windows forms.

What do you mean by "disable the print screen"? You want to stop people copying text off your application using the clipboard? You want to stop people taking screenshots (in which case, I think you're out of luck!)?
|

You can disable print screen keys (PrtScrn and Alt-PrtScrn) by redirecting the hot keys to your applications main window. But there is no way you can't stop another application, like ScreenGrabber, from grabbing the screen, and your graphic images.

I thought dvd player apps could prevent 3rd party apps from doing screen grabs. I assume they do it by accessing hardware at a lower level than the win32api provides access to.

Not really. You're grabbing exactly what you should, the image in the frame buffer. The frame buffer just happens to be blank in the video window. The video you're seeing isn't being shown in this frame buffer, but is an overlay rendered by a different part of the video card.

Use the following:

Hello,
I am trying to hide a certain column in a DataGrid, but to no avail. Here is the part of the code:
<br />
this.dataview.Table.Columns["VersionID"].ColumnMapping = MappingType.Hidden;<br />
this.dataGridCashFlow.DataSource = this.dataview;<br />
Any ideas, why it would not work? Column VersionID still shows up in the DataGrid
Thank you

Add a DataGridTableStyle object to your DataGrid and include only the columns you want visible in it's GridColumnStyles collection.
|
|
|
|
|
use tablestyle and set the column width = 0
***********example of some of the code************
tsGrid.MappingName = "data";
// Add it to the datagrid's TableStyles collection
dgClientView.TableStyles.Add(tsGrid);
// Hide the first column (index 0)
dgClientView.TableStyles[0].GridColumnStyles[0].Width = 0;
Don't know if this is what your looking for?

Yeah, I did that and it was wroking. (setting the width to 0). I just wanted to know how come the Mapping command did not work.
Thank you very much for the input guys.

Hi
I want to create a Form in a constructor (or the load event) like this:
public class Form1
{
private Form fm;
public Form1()
{
fm = new Form();
fm.Show();
}
}
It is important for me to use Show() and not ShowDialog(). The problem is, that the Form is created and displayed, but it does not react on any mouseclick (or move...). When I use the same code from within a Button callback everything works fine. As far as I could figure out by now, there is no Messageloop created in the CTOR or in the Load callback.
So what options do I have?
Thanks in advance
remarks:
The Form1 was created in an extra Thread. This seems to cause the problem. But I need this Thread.

Logically, the problem is that Form1 hasn't been created yet nor is it isn't ready to be a "realized window" and yet you've created another window and tried to realize that. There is simply a mistiming of events in your logic (child window is created and displayed before the parent is created and displayed). I'm not surprised that fm never "appears".
I would seperate these Forms or at the very least move the Show of the child form out of the contructor. You can still "parent" the one form off the other even if they are complete seperated objects. If you still want to agrigate the child form, show it on the Load event. That is my best guess without writing or compiling test code.

Your only option is to run a message pump on that thread also, using the Application.Run[^] method.
public Form1()
{
fm = new Form();
Application.Run(fm);
}
Regards

I need to know where to check for system status? like messenger 'Away' after say 5 minutes. I need to run code when it goes into such a status, and again when it returns to normal.

In 1.1, static is not an object level modifier. Just define all of your functions as static instead and you'll get the effect you desire.
