Hi Paulo,

I'm curios about it when you have published it. But I wonder how many lines you need for this project, because the author only need to make a few changes.

My control is written in C++ / MFC. It takes more than two lines of code to produce this, but it gives you a lot of control over what is happening.

Using a thread in a dialog project

Hi, I need to use the same thread for several Dialogs. I do it for one dialog and it works, because I associate it with this dialog. But If I want to use it in another dialog, ¿How can I do it? How can I associate it with several dialogs?

Another question: How Can I use a member class dialog variable in another Dialog code?

Thanks.

Javier

That may be a questionable programming practice. Isn't there any other place where you can put that variable that is accessible to all dialogs?

Yes, sorry, I only need two variables managed in the thread that they could be accessible from all dialogs, and I need to resume or to stop the thread from a button in any dialog.

How can I do it? I only need to know to make accessibles threads variables(or member variables) or something else.

Try a global object. Not a clean solution, but works.

Language purists don't like globals... that's all. I regularly use globals and it's very easy to do. I create two files, one named "globals.h" that is included in all cpp files that need to access the global variables. For instance:

#ifndef __GLOBALS__
#define __GLOBALS__

extern int g_nInteger;
extern HANDLE g_hThread;

#endif

Now, you include in your project a cpp file named "globals.cpp":

#include "stdafx.h"
#include "globals.h"

int g_nInteger = 0;
HANDLE g_hThread = NULL;

And that's all you need.

USB Host Ports

Hi,

We have a embedded product that contains a USB1 host port on it. We have a thought of using a USB connection to transfer data from a PC to the product. However PC's have host ports and our product has a host port.

Is it possible to connect these 2 hosts together, and if so does anyone know how?

thanks,
Rich

I'm using Entrek CodeSnitch to detect memory leaks. The strange thing is that i get a Error: Memory verwrite detected at... at the beginnig of the events sequence. I tried to write a blank MFC application with AppWizard and it reports exactly the same error.
Is there a problem with Entrek CodeSnitch or with MFC?
Thank you.

Moving Items in a DataGrid

Mitch F.30-Nov-04 8:02

30-Nov-04 8:02

Hello,
I've been trying to move items up and down in a DataGrid in the .Net Compact Framework, using Visual Basic .Net 2003. I have tried using the InsertAt command, but I have not been able to get it to work.

Here is my current code to move an item up:

Dim currentpos As Integer
currentpos = DataGrid1.CurrentRowIndex
If currentpos >= 0 Then
Dim row As DataRow
row = DataTable.Rows(DataGrid1.CurrentRowIndex)
Dim NewRow As DataRow
NewRow = DataTable.NewRow
NewRow(0) = row.ItemArray.GetValue(0)
DataTable.Rows.RemoveAt(DataGrid1.CurrentRowIndex)
DataTable.Rows.InsertAt(NewRow, currentpos - 1)
End If

My code seems to sometimes work, other times it moves two items up, and sometimes it moves items around randomly.

Could anyone please help?

Thanks

Win CE/PocketPC audio playback

29-Nov-04 13:21

I need to write a .NET compact framework application that play a playlist of MP3 audio items on a Pocket PC(Win CE). The items need to be overlapped and/or played simultaneously.

It looks fairly simple to do overlaps of linear (noncompressed) files in DirectX or to play MP3's using the Windows MediaPlayer but how do I do both.

I have tried to find out what approach to use to be able to do this.

Any suggestions?
