Try this

SetWindowPos(&this->wndTopMost,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);

Thanks u for ur reply,i put it in the class where this window created,but it show me errors like there r few arguments and it can't recognize "this", one more question:how can i get the hwnd of my window? In msdn i look for the setwindowpos and and i realise that i need this...
if u have time please answer me.....!!!!
Thanks

I have recently installed fresh windows and curently i can't check if it is correct, but i think it is GetActiveWindows or FindWindow

Thanks one more time, maybe i m wrong but i create my opengl window with glutCreateWindow and everything was created with glut expresions, it creates an int type window and i can't convert it to HWND, is there any other way to make it topmost or to make an notopmost my vb.net window?...

Hello.
I thing the HWND is a LONG INT, but hwnd is used in c++ not in VB. "this" is a pointer used in C++ and in C#.

don't know if it helps, but in VB, this is replaced by me.

The code I gave you was MFC, and you need to convert that to the VB.NET equivalent. I don't know VB.NET so you'll have to ask a VB.NET guy to convert it for you.

In MFC(dll) i want to put that code because i want to call it from the VB.NET. Here is my code where i create my opengl window and all the values was given by the VB.NET. Any idea guys?
I try to find an expression in glut,glu libraries i didn't find anything!!
I want this window being in front of the VB form!!!!

void
create(int _posx,int _posy,int _sizex,int _sizey)
{posx=_posx; posy=_posy;sizex=_sizex;sizey=_sizey;
glutInitDisplayMode(GLUT_RGB | GLUT_DEPTH | GLUT_DOUBLE | GLUT_MULTISAMPLE);
glutInitWindowPosition(posx, posy);
glutInitWindowSize(sizex, sizey);
//SetWindowPos(hwnd,HWND_TOPMOST,0,0,0,0,SWP_NOMOVE|SWP_NOSIZE);

main_window = glutCreateWindow( "GLUI Example 5" );
CWnd::wndTopMost;
glui2 = GLUI_Master.create_glui_subwindow( main_window,
GLUI_SUBWINDOW_BOTTOM );
glui2->set_main_gfx_window( main_window );

GLUI_Rotation *cubform_rot = glui2->add_rotation( "CubiForm", CubiForm_rotate );
cubform_rot->set_spin( .98 );
glui2->add_column( false );
GLUI_Translation *trans_xy =
glui2->add_translation( "Objects XY", GLUI_TRANSLATION_XY, obj_pos );
trans_xy->set_speed( .005 );
glui2->add_column( false );
GLUI_Translation *trans_z =
glui2->add_translation( "Objects Z", GLUI_TRANSLATION_Z, &obj_pos[2] );
trans_z->set_speed( .05 );
glui2->add_column( false );

GLUI_Rollout *options = glui2->add_rollout( "Ortho", true );
glui2->add_checkbox_to_panel( options, "Draw Ortho", &show_ortho );
glui2->add_checkbox_to_panel( options, "Reset", &reset,0,(GLUI_Update_CB)mouse);

glui2->add_button( "Quit", 0,(GLUI_Update_CB)exit);
init();

}

I am writing a small applet which will read/write data in a binary file. BinaryReader/BinaryWriter is not quite compatible. I figured a mixed assembly of C++/CLI and native code would work perfectly and be educational as well. Unfortunately, all my attempts at doing this have failed. (I might add that if MS wants anyone to use C++/CLI, they need to make the IDE much more friendly to it.)

My preferred way of learning is by examining and stepping through working code. So, can anyone guide me to some a sample project doing something comparable that I can look at and step through?

Hello Joe

Why are the BinaryReader/BinaryWriter classes not suitable?

Also, why don't you just use CreateFile or one of the C or C++ file functions in your code?

Due to some low level data manipulation that needs to take place before the high level managed classes take over, indicatios are that I will get a huge performance boost by keeping that low level in unmanaged code.

As for CreateFile, that's what I intended to use in the unmanaged portion of the code. The problem is that for all the talk about C++/CLI, I have had a difficult time finding actual working mixed code I can use to learn this stuff. My only solution is to write straight C/C++ based native DLLs and P/Invoke into them from the .NET assemblies.

Just use your CreateFile calls and compile with /clr. I've done it before without problems.

You misunderstand. I have simplified the problem just to give some indication of what I was trying to do. It is absolutely essential that the core of the solution run natively. I want an assembly with a mix of managed and native classes. I want to find a working EXAMPLE on how to do this.

Thank you anyway for your help.
