I have started writing a class to create a d3d window, but every time i make a call to BeginScene,EndScene or Present my computer restarts. The following is my d3d initiation code which i run after creating a window, and then i try to run the functions from my main message loop. Could anyone please help, I'm having trouble debugging soon as my computer reboots everytime it doesnt work.

if((procIdle==NULL)||(procRender==NULL)||(procPreRender==NULL))return 1;
if(FAILED(lpD3D = Direct3DCreate9(D3D_SDK_VERSION)))return 2;
if(FAILED(lpD3D->CreateDevice
(D3DADAPTER_DEFAULT,D3DDEVTYPE_HAL,hWnd
,D3DCREATE_SOFTWARE_VERTEXPROCESSING,&prm,&lpDevice)))return 3;
for(int i = 0;i < 209; i++)
if(render_states[i]!=NULL)
if(FAILED(lpDevice->SetRenderState
((D3DRENDERSTATETYPE)i,render_states[i])))return 4;;;
initiated = true;
return 0;

The computer restarting points to a driver bug.

Are you using the latest drivers for your video card?
Are you testing with the debug D3D runtime?

PostMessage() problems

Hi,

i have inherited a class from CEdit, and want to send my application a user defined message from this class. i have used PostMessage function for that reason from my class's LBUTTONDOWN message.

The message is captured by my window (a dialog box that has an edit box linked by a variable of my class) and works well while i work in Debug configuration, but causes an unhandled exception in Release Configuration Confused | :confused:

.

I would be obliged if any one can help me..
--------
THE CODE SAMPLE:
--------
Dev. Platform : VC++ 6.0
OS: Windows 2000 Professional

//class definition
class CMyClass : public CEdit
{
...
}

Void CMyClass::OnLButtonDown(UINT nFlags, CPoint point)
{
// my code...
....

CEdit::OnLButtonDown(nFlags, point);

//m_hParWnd is the handle of parent dialog claas
::PostMessage(m_hParWnd, TOGGLE, 0, 0);
}

/*My applications main dialog with a member variable of CMyClass associated with an edit box*/
..
ON_MESSAGE(TOGGLE, OnToggle)
...

CMyAppDlg::OnToggle()
{
....
}

Is m_hParWnd non-NULL? If you comment out this statement, does the UE still occur? Does anything special happen within the OnToggle() method?

You are defining an incorrect handling function in your CMyAppDlg, the right way to do so is:

// in MyAppDlg.h
class CMyAppDlg : public CDialog
{
    // ... ...
    afx_msg LRESULT OnToggle(WPARAM wParam, LPARAM lParam);
    // ... ...
}
  
// in MyAppDlg.cpp
ON_MESSAGE(TOGGLE, OnToggle)
  
LRESULT CMyAppDlg::OnToggle(WPARAM wParam, LPARAM lParam)
{
    // ... ...
    return (LRESULT)0;
}

This will work fine.

UpdateLayeredWindow() Help !!!

4-Dec-03 8:50

I do not understand how to use this API. Like I need a little bit more information then what MSDN has to offer and some of the sample code on CP. This is what I am trying to do. I am trying to make it so that when I send a WM_CLOSE message the window fades slowly away. But if I use SetLayeredWindowAttributes(), works no problem. But I want to use UpdateLayeredWindow(). I have tried everything to get it to render the window. Sometimes just the copy of my IDE shows up. Now How do I set this function up??? I am coding in win32 C/C++ -> No MFC. Any help would be great. I have spent 2 days trying to figure this crap out. With no help from anywhere except u guys. But I dont understand all the MFC code to dissect it.

Thank You
Gino

Hi fellow programmers!
I was wondering what is the latest beta of Visual Studio .NET that can compile AMD64 code for Windows XP 64-bit?

Thanks for your answers!

Currently the only shipping AMD64 compiler from Microsoft is in the Driver Developers' Kit[^]. The same is also true for the Itanium compiler.

These are only command-line compilers, so you should consider using a separate build tool, such as the DDK's BUILD.EXE, NMAKE.EXE or NAnt[^].

The x86 compiler is basically the same one that VS.NET uses (VS.NET compiles by running the cl.exe program).

I'd be impressed if you'd managed to get hold of an AMD64 system running Windows XP 64-bit, because that hasn't been released yet, IIRC. If you've only installed the regular version of Windows XP, you won't be able to run native 64-bit programs. The compilers in the DDK are cross-compilers - they are actually 32-bit x86 programs, but they build for the appropriate platform (although MS does supply an Itanium-native Itanium compiler).

I am an independant developer, developing a software for AMD. I have their fullsuppot and will be getting the latest build of Windows XP 64-bit next week. I am not at liberty to say more about the project or I would have.

I know I read somewhere that there is a beta of Visual Studio.NET with AMD64 available in the IDE. I already asked my contact in AMD for that. And will post the answer here if possible.

VS .NET window type

Anyone knows what kind of window is the one that holds our files in Visual Studio .NET ? The Window as a nice property that i would like to use that is, auto-hide. The window shows up when we pass the mouse cursor over it and automatically gets hidden when the mouse cursor isn't on top of it. Anyone ?

Thanks.

This is custom implimented behaviour, not behaviour you can get from deriving from an existing class in the framework.

Layout controlbars?

Zizilamoroso4-Dec-03 7:20

4-Dec-03 7:20

I have several CControlBar derived bars attached to a CFrameWnd.

It seems the horizontal bars always have stretch priority over the vertical ones (more or less like borderlayout in java).

example: the bottom bar is always stretched from left to right first, so the right bar cannot stretch to the bottom anymore.

But I would like the right bar stretched to the bottom, before the bottom bar is streched.

How can I change this?

Replace MFC with Web Browser

I have been writing software for the Windows environment using Visual Studio .Net (C++).
However as some groups have been using VME PowerPC h/w with VxWorks operating system. Now with the need to re-use software and develop 'common' s/w items between the two platforms. The idear to use a Web Browser to provide the common GUI was suggested.

Could use complier switches to cope with the different platforms, but need to separate out the GUI and make it identical on the platforms.

Question is, can the elements of MFC be replaced by a Browser?

i.e. the Browser communicate with the C++ task (C++ task with no Windows input/output), using TCP/IP?

enable profiling in .net 2003

Dear All,

In Visual C++ 6.0 there used to be this very useful thing called a profiler. In the settings you could enable profiling and when the program was started the profiler spat out all kinds of useful information (what functions were called, how often and how long it took.)

Now I'm using .Net 2003 and I don't really know why... VC++ 6.0 was and still is really good...

My question: Is there a profiler in .net 2003 (I couldn't find it) and if so, how do I enable it?

Best regards,

Jon

There is no profiler built into VS.NET. CompuWare ships a free "community edition" profiler which is the current replacement. The url is:

Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Dear Joe,

this was a very valuable tip! Thanks! I downloaded the thing and it seems to work well. It seems to have a lot of features not included in the old VC++ 6.0.
Thanks again,

To my knowledge, an application has no knowledge about how (command prompt, Windows Explorer, Run box) it was started.

Thanks very much.

A very interesting thing would also be
to use the STDOUT of the Console the App was started from.

Also the ability to 'block' this console
(probably a cmd.exe window) from the windows application.

The answers where fast responses Smile | :)

Thanks so far.

The best thing I found currently on
the net releating to my problem but not really
finishing it was found on:

http://codeguru.earthweb.com/console/Console.html

The Question is:

Could I produce not too wicked code
to make the GUI.exe behave
exactly the same as the Console.exe
if it is started from a console-Window?

My Problem from a WinMain or CWinApp object is
the imediate return inside the console Window.

'Similar' Effect for a CWinApp could possibly produced somehow with

HWND hwnd = FindWindow("ConsoleWindowClass", zInstanceName);
if (hwnd)
{

releating to:
http://support.microsoft.com/default.aspx?scid=KB;en-us;q124103

But how can I be certain that it was my Console that
I possibly find.

And what am I allowed to do on this Console.

Thanks
