I'm stuck in this CControlBar hell, using the wonderfull CSizingControlBar, I need to be able to do some stuff when the user closes the floating bar, when he presses on the x button, which is different than when the user show/hide the bars, because I can handle the menu item in the mainframe.
by default, the floating control bar frame is a CMiniDockFrameWnd, see the deeply undocumented m_pFloatingFrameClass member of the CFrameWnd class. so, when I use a CSizingControlBar, the frame is "hard coded" to CMiniDockFrameWnd. and I can't handle messages for it, and I can't handle the close.
So, as explained in the the CSizingControlBar documentation and code, I can replace the pFloatingFrameClass with my own CMiniDockFrameWnd derived class, this kinda' work, but will this replace the miniframe for all toolbars ? yep, looks like it,
I was able to fix this by using my own CMiniDockFrameWnd derived class to handle the WM_NCLBUTTONDOWN and check for HTCLOSE ... and do my stuff, and I also needed to handle the same kind of things when the bar is docked ...
Anyway, I think that the way the controlbars are handled are the work of the devil!
now, go about your daily business ...

Ok, I'm modifying someone else's cool OpenGL program. All I wish to do now is to add some cool zoom functions (it's a 3D mapping program).
I was thinking that when you would click on a spot, it would zoom in on it. So I found these functions:
SetViewportOrgEx() // I would use this to set the new orgin
ScaleViewportExtEx() // I would use this to zoom in
I put them both in my code, but nothing happened! No errors, no screen changes, no bad return values--nothing!
If you have any ideas (or even another way to do it), please help! This functionality would be really cool to the program,

Bonjour,
I don't where you put this code but you need to put it on the OnPaint event like this :
void CTNSImageCtrl::OnPaint()
{
PAINTSTRUCT ps;
CDC *cDC = BeginPaint(&ps);
// SetMapMode(cDC->m_hDC, MM_LOMETRIC);
SetWindowOrgEx(cDC->m_hDC, 0, 0, NULL);
SetViewportOrgEx(cDC->m_hDC,
-GetScrollPos(SB_HORZ),
-GetScrollPos(SB_VERT),
NULL);
OnDraw(cDC, &ps.rcPaint, NULL);
EndPaint(&ps);
}
Here is a sample where i just move not scale for the scale i use another way !!!
Simplicity is the supreme sophistication.

If it is really an OpenGL program as you stated then the GDI Viewport functions will have no effect on it. There are two techniques commonly used to zoom in on an object in OpenGL. Either add a scale call (GLscalef(x,y,z) I think) and incrementally bump up the scale factors to increase the size of the object or move the camera gradually closer to the object. There are OpenGL samples on this site that demonstrate this.

Well that explanes my problem! First of all, the person who origonally wrote this prog said that maybe a glscale() function existed. I can't find either your version or his of this function.
Also,I don't suppose you happen to know if I really need a z value. I would assume for a zoom-in function, you would simply decrease x and y to make it appear that you are zooming in.
If you have a problem with my spelling, just remember that's not my fault. I (as well as everyone else who learned to spell after 1976) blame it on Robert A. Kolpek for U.S. Patent 4,136,395.

You talked about 3D, so the z value is necessary.

... decrease them by dividing them by a value which appears to be related to z ....

Hello all,
I had a question regarding how to get to the View of a particular window. I created an MDI application without doc/view support. When I hit File->new, a new window appears thansk to this App Generated Code
CMainFrame* pFrame = STATIC_DOWNCAST(CMainFrame, m_pMainWnd);
// create a new MDI child window
pFrame->CreateNewChild(
RUNTIME_CLASS(CChildFrame), IDR_NICKMITYPE, m_hMDIMenu, m_hMDIAccel);
My problem is that I wish to open a DIB into this new window. Everytime I open the DIB though, it goes to the background of my application and not to this new window. I have determied that this happens due to the fact that when I call GetView(), it returns &m_wndView. m_wndView is the view of the ChildView class, and hence it always appears as the background (right?). How can I get to the View of the Child Window that was created? Please help me out, or let me know if I am going about this in the right way.
I am thinking that what I should do is write a new view class, and have the DIB open into a new window using this view class. What do you guys think?
Thanks,
NickOne

Hi,
I'm working on an Add-in for VS6. One of my pb is to deal with modeless dialog.
When I use a non modal window, I do not catch all the messages from the keyboard anymore. For instance, if I type some text in an edit box, everything is fine except for the DEL key (same with Escape, Ctrl-Z, etc.) which acts in the VS editor window behind...
If you have any suggestions...

Hi,
how do I enable the Edit-Menu for a RichEditCtrl that I have docked in a CtrlBar ?
I thought there was an article here, but I don't find it anymore.

Hi, I've been working with Ole DB and I'd like to be in touch with people who work with it too, because there is a lack of information on this matter. What we can find on microsoft's examples is raw code..Maybe we can open a forum here...what do you think...send comments

Take a look at the code for the DrawTheText member function in Davide Calabro's CButtonST v3.7 (MFC Flat buttons)[^] article here on CP.

Hi,
I´ve been using the Crypto API to sign digital messages.
Everything works fine under windows 2000, but when I try
to sign a message under windows 9x it just doesn´t work.
After I click the button the system brings nothing back as
if hasn´t found the certificate.
The code executed for retrieving the certificate is:
if(myCert.FindBySerialNumber(issuer,sn))<br />
if(m_cryptmsg.SignMessage(&myCert,m_texto,&pbData, <br />
&cbData))<br />
{<br />
blob = new CCryptoBlob( pbData, cbData );<br />
m_lpRet = (LPSTR)blob->ToBase64(); <br />
blob->Release(); <br />
}<br />
else<br />
_tcscpy(m_lpRet,_T(""));
Is there anything that should be done different for it to
work under Win 9x? 
Thanks in advance

I have an application that has a tab-page on which some controls can be placed. These controls are created in a DLL. When I try to delete these controls from within the DLL I get an assertion failure in the CWnd::DestroyWindow of the controls at ASSERT(m_hWnd == hWndOrig);.
Anyone know how to fix this? ...it is realy anoying me.
<br />
BOOL CWnd::DestroyWindow()<br />
{<br />
if (m_hWnd == NULL)<br />
return FALSE;<br />
<br />
CHandleMap* pMap = afxMapHWND();<br />
ASSERT(pMap != NULL);<br />
CWnd* pWnd = (CWnd*)pMap->LookupPermanent(m_hWnd);<br />
#ifdef _DEBUG<br />
HWND hWndOrig = m_hWnd;<br />
#endif<br />
<br />
#ifdef _AFX_NO_OCC_SUPPORT<br />
BOOL bResult = ::DestroyWindow(m_hWnd);<br />
#else //_AFX_NO_OCC_SUPPORT<br />
BOOL bResult;<br />
if (m_pCtrlSite == NULL)<br />
bResult = ::DestroyWindow(m_hWnd);<br />
else<br />
bResult = m_pCtrlSite->DestroyControl();<br />
#endif //_AFX_NO_OCC_SUPPORT<br />
<br />
if (pWnd != NULL)<br />
{<br />
#ifdef _DEBUG<br />
ASSERT(pMap->LookupPermanent(hWndOrig) == NULL);<br />
#endif<br />
}<br />
else<br />
{<br />
#ifdef _DEBUG<br />
ASSERT(m_hWnd == hWndOrig);<br />
#endif<br />
Detach();<br />
}<br />
return bResult;<br />
}<br />
|
|
|
|
|
What's the value of bResult before the assertion fails ?
~RaGE();
|
|
|
|
|
When the assertions fails:
bResult = TRUE
m_hWnd = 0x00000000
hWndOrig = 0x000408e6
|
|
|
|
|
I do not understand why it souhld _not_ cause an assertion here. You destroy the window (since bResult is true) so m_hWnd is NULL, so pWnd is NULL, so m_hWnd cannot be equal to m_hWnd since it takes the original value of hWndOrig with HWND hWndOrig = m_hWnd;. I really do not see the point in all this

I cannot figure it out either, some source comment would have been handy. Also, I can not find anything about this problem on the whole damn internet (google search). I guess I just have to put up with it and try to restain myself from smashing my keyboard.
|
|
|
|
|
Are you using the AFX_MANAGE_STATE( ) macro at the top of the function in the dll that destroys the window?

That's It! I thought I already added it, but I hadn't done so in the destructor. Thanx !

hi, just implemented in-place editing for list control as illustrated by:S.Prabhakarreddy / CodeProject
Reference: http://www.codeproject.com/listctrl/editing_subitems_in_listcontrol.asp
QUESTION 1: How can I use arrow keys (Keyboard) to navigate around the list control?
QUESTION 2: The implementation at the moment is such that you click on a cell, type and press ENTER. But what's better is click, type and press ARROW key. But how? I tried OnKeyDown for the dialog class. But not much luck.
QUESTION 3: Seems like ListView_GetSubItemRect is not doing its job properly... the following is code in message handler for click on list control:
// this macro is used to retrieve the Rectangle
// of the selected SubItem
ListView_GetSubItemRect(
hWnd1,
temp->iItem,
temp->iSubItem,
LVIR_BOUNDS,
&rect);
//Why +13? It's just trial and error. Seems like ListView_GetSubItemRect is not doing its job properly.
::SetWindowPos(::GetDlgItem(m_hWnd,IDC_EDIT1),
HWND_TOP,
rect.left +13, //You need to compensate for the deviation u get from ListView_GetSubItemRect!?!
rect.top +13,
rect.right-rect.left,
rect.bottom-rect.top,
NULL);
Thanks!

If you want to be able to jump between cells using arrow keys you have to intercept them in the editbox itself because the editbox receives the keydown event. I did similar things once (using the TAB key to move between cells) and the code looked something like this:
<br />
<br />
void CInPlaceEdit::OnChar( UINT nChar, UINT nRepCnt, UINT nFlags )<br />
{<br />
if ( nChar == VK_TAB )<br />
{<br />
if ( GetKeyState( VK_SHIFT ) < 0 )<br />
{<br />
m_pListCtrlParent->OnPreviousCell( );<br />
}<br />
else<br />
{<br />
m_pListCtrlParent->OnNextCell( );<br />
}<br />
}<br />
}<br />
<br />
where m_pListCtrlParent is a pointer to the parent Listctrl. It contains the method called in the code and these methods basically do this:
- grab the focus (because the edit box knows that it should disappear when it loses focus)
- calculate the next cell to be edited
- initiate the edit for that cell
