Hi guys!
I'm a beginner and I have some problems with the project I am working. It's a MDI without doc/view.
I just want to know how I can use a splash screen. I have read that there was a splash screen component in VC++ 6 but I cannot find it in .NET. Also, I want to change the icon and the title of my child windows. I've been able to change the size and the position of my child windows but I can't change the name and the icon.
I used
BOOL OpenGL_ContextMFC::PreCreateWindow(CREATESTRUCT& cs)
{
// TODO: Modify the Window class or styles here by modifying theCREATESTRUCT cs
if( !CMDIChildWnd::PreCreateWindow(cs) )
return FALSE;
cs.lpszName="My new name here doesn't work";
cs.cx = 500;
cs.cy = 500;
cs.dwExStyle &= ~WS_EX_CLIENTEDGE;
cs.lpszClass = AfxRegisterWndClass(0);
return TRUE;
}
any ideas?
thanks

Yup there is a splash screen component in VC 6....its very simple to use...
I dunno why u need in .NET.
Then to change the Icon..Its simple...Replace the icon which u want to load with the existing thing in the resource file(.rc)...and i dunno which name ur talking abt.....So be more forthcoming...
cheers,
Super

I have a dialog app that I use to call other dialogs to display and get information.
When a user presses a button I call up a dialog like so:
CMALF2Dlg *pdlg;
pdlg = new CMALF2Dlg;
pdlg->Create(IDD_MALF_2,this);
and when I close the dialog I use:
DestroyWindow();
PostNcDestroy();
delete this;
After doing this it deletes some of the memory, but leaves about 4k out there. After calling and closing a few times it seems to settle at two memory values one before the call and one after. Is this normal or am I missing something here? Maybe I'm missing some other memory management code.
Thanks for the help,
Jim

Hmmm, delete this should take care of everything, including calling DestroyWindow window, so there's no need to call it yourself.
Anyway, the reason for the memory leak is not apparent, but if you run the app in the debugger and then close it, you should see exactly where the memory that's leaking was allocated.
You may also consider taking a different, simpler approach. But it depends on whether you want to allow the user to create multiple CMALF2Dlg boxes everytime the button is pressed. If you DON'T, then great! I have the perfect solution, create it as a static variable:
static CMALF2Dlg s_dlg;
if (!::IsWindow(s_dlg.m_hWnd))
s_dlg.Create(CMALF2Dlg::IDD, this);
s_dlg.ShowWindow(SW_SHOWNORMAL);
Then you can get rid of the delete this as well as the memory leak.

Hi!
I want to make a system call to run a C executable from my another c code.
How can I do that?
Thanks

You have several alternatives, from simplest to most complex:
1. system
2. WinExec
3. CreateProcess

I think My problem is So Basic. 
i explain my problem again!
i have a SDI MFC project. i define an Modless Dialog Box and Show it beside the Main Document Window.i define it in CDemoView (My Main Class of Project) i can Set properties of that Dialog's Controls for Example i can Set the Caption of a Static-Text object that Exists in that Dialog Box.
So my problem is i Still Can't Capture Events of that Dialog Box Buttons.
for example if i Click a Button in that Dialog i can't Send_Message to CDemoView or Call a Function of CDemoView.
if i add an Event handler of that Button in CDemoView it will don't respond.i should add Event Handler only in that Dialog Class to respond. (i donno Why Event Handler Shows another Classes when i choose event handler for that Button . becouse only Dialog Class Responds to Events)
my another Quiestion:
i know that i can Define an Object of Current CMainFrame Class's object:
CMainFrame* pFrame = STATIC_DOWNCAST(CMainFrame, AfxGetMainWnd());<br />
pFrame->HidePalette();
how can i Define an Object of CDemoView Class Like this. in this code if i change CMainFrame to CDemoView an Error Occurs : Debug Assertion Failed. 
thanks Anyway,

ok here we go
in ur dialog box button message handler have something like:
PostMessage(AfxGetMainWnd(),WM_USER+10,0,0)
in ur main window have a message map entry for that message that processes the button click
just remember ur getting the message in the dialog from when the button is clicked and sending a message to another part of ur app to deal with it

thanks Lauren. i get what u explaind.
but when i use something like this :
<br />
void CDialog::OnBnClickedButton1()<br />
{<br />
AfxGetMainWnd()->PostMessage(WM_USER,0,0);<br />
}
it send message to CMainFrame Class. i have to Captute this Message in CDemoView.
it seems that this is the Routine Usage of Capturing messages of a Button and there is Something Wrong with me.
isn't it ?

|

no theres nothing wrong with u
i used to get confused as hell when i was learning mfc and all the message maps and that stuff
hmmmmm i still do sometimes
if u have an understanding of the big picture it all falls into place gradually
yes ... capture the message u sent urself in the mainframe and do the processing there

duh its an sdi app
AfxGetMainWnd() should be the main window of ur app??
unless im getting very confused??
CDemoView* pView = (CDemoView*)AfxGetMainWnd();

unfortunately this also Creats an Object of CMainFrame!!!
CDemoView* pView = (CDemoView*)AfxGetMainWnd();
|
|
|
|
|
in ur debugger it will show as a mainframe but i just tested it in a quick app i built and the cast ptr is a ptr to the main view window
from a dialog i did:
CXView *pView = (CXView*)AfxGetMainWnd();
then:
pView->SomeViewClassFunction();
and it worked fine
???

It's long but it works:
Crate the dialog with the wizard and then crate dialog from that resorce IDD_!
Show the dialog!
Handle the Events of that Dialog Box in same Class and from there change what you want in class CDemoView, but you will need a global pointer of CDemoView in order to use it in Dialog Box functions!

Exactly!!
but how can i define a Global pointer to CDemoClass ?????
is it possible??
|
|
|
|

In the begining of CDemoView *.cpp file declare global variable as
CDemoView* gCDemoView = NULL;
At the end of CDemoView constructor write
gCDemoView = this;
In the end of CDemoView destructor reset the pointer to NULL so you would know that no
longer exist
gCDemoView = NULL;
Now you can use that pointer anywhere in you code!!

Using global variables in an object oriented code seems an heresy and a dirty way to me. Just my 2 cents.

I'm not sure you need a global pointer, MFC gives all the methods needed to access its objects.
I suppose you are using the document-view architecture, and CDemoView is the view class of the application.
You can get a pointer on your main frame using
CMainFrame *pMyFrame = (CMainFrame *)AfxGetApp()->m_pMainWnd;
Your app being SDI, you can get the active view from the main frame using:
CDemoView *pView = (CDemoView *)pMyFrame->GetActiveView();
(because when using print preview the active view may be the preview view instead of your view, you should perhaps make the following test
CDemoView *pView = (CDemoView *)pMyFrame>GetActiveView();<br />
if(!pView || pView->IsKindOf(RUNTIME_CLASS(CDemoView))<br />
return;
Another way, perhaps safer, is to get the active document from the MainFrame (CDocument *CFrameWnd::GetActiveDocument) and then, from the document, accessing the view(s) it may own (CDocument::GetFirstViewPosition, CDocument::GetNextView)
HTH,
K.
