I have the handlers and message maps as below.
Whenever a child window is visible the following hanldler and its update function is not invoked.
When the Child window is closed they are invoked..
Can anyone explain this behaviour.
ON_COMMAND(ID_VIEW_DRAWTOOLBAR, OnDrawToolBar)
ON_UPDATE_COMMAND_UI(ID_VIEW_DRAWTOOLBAR, OnUpdateDrawToolBar)
void CMainFrame::OnDrawToolBar()
{
if (m_bUICtrlBar)
{
m_bUICtrlBar = false;
ShowControlBar(&m_UICtrlsBar, m_bUICtrlBar, false );
}
else
{
m_bUICtrlBar = true;
ShowControlBar(&m_UICtrlsBar, m_bUICtrlBar, false );
}
}
void CMainFrame::OnUpdateDrawToolBar(CCmdUI *pCmdUI)
{
if (m_UICtrlsBar.IsVisible())
m_bUICtrlBar = TRUE;
else
m_bUICtrlBar = FALSE;
if (m_bUICtrlBar)
{
pCmdUI->SetCheck(TRUE);
//AfxMessageBox("visible so check");
}
else
{
pCmdUI->SetCheck(FALSE);
//AfxMessageBox("Invisible so Uncheck");
}
}

hello!
i want to create check boxes on run time in the groupbox but i dont know how to do this plz tell me.and give detail procedure
|
|

Connect a variable to your groupbox: CButton m_Stat;
1-
CreateWindow("BUTTON","this is checkbox",WS_CHILD | WS_VISIBLE | BS_CHECKBOX | BS_AUTOCHECKBOX | WS_TABSTOP,20,10,200,20,m_Stat.m_hWnd,NULL,AfxGetApp()->m_hInstance,0);
-OR-
2-
You can also use CButton: Just make the CButton variable at class level.
static CButton b;
CRect rect;
rect.SetRect(20,20,200,40);
b.Create("Hello oo",WS_CHILD | WS_VISIBLE | BS_CHECKBOX | BS_AUTOCHECKBOX,rect,&m_Stat,20);
If you need to use plain win32, then it is a bit different.
this is this.

but this create only single checkbox and i want to display single check box on each click event.means i want to display 1 checkbox then on next click event another next to previous.
|

|

well you did not say so on your initial post ...
but I still don't understand what you want to do ?
you want to create a new checkbox control each time the user clicks somewhere ?

ya actually i want to open no of files at same time and each time when i click on open file on file menu a check box would be created on each open file action as i would open another file the next check box would be opened on group box next to previous one.
hope u'll understand now

Create a CPtrArray m_ptrArray; variable in your header.
Then when you want to create the checkbox,
CButton* pButton;
pButton = new CButton;
...
Create the button using the code in reply above.
...
Then add it to the array like this:
m_ptrArray.Add(pButton);
Now your checkbox is created and added to the array for later usage.
When you need to access it, use:
CButton* pButton;
pButton = (CButton*)m_ptrArray.GetAt(iLocation);
where iLocation is the index of the button starting with 0...to m_ptrArray.GetSize();
this is this.

StretchBlt can be done for Bitmaps.
How do I do the same for ICONS.
I need to zoom an icon.
Any suggestions plz.

How about DrawIcon into a memory DC, then BitBlt from the mmemory DC to your destination DC?
|
|
|
|
|
StretchBlt can used with bitmaps to implement zooming.
How can I do the same for Icons to bring about its zooming effect

Hi all,
Since starting to use STL (mainly vectors), I've found that VC++6 (latest SP) is crashing more and more frequently when compiling, the more STL code I use. It then compiles OK if I restart the IDE. Is this a common problem? Any fixes?
TIA,
Steve.

|
|
|
|
never seen this, but instead of restarting the whole IDE, what about just rebuild all ?

The IDE itself locks up and has to be killed with the Task Manager.

Anyone knows how to set the description text for a Windows Service? (the text in the second column of the Services MMC window).
Tnx
|
|
|
|

If your program only runs on Windows 2000 or later, use ChangeServiceConfig2 with the SERVICE_CONFIG_DESCRIPTION if the service is already installed.
Otherwise, you will need to edit/add a registry entry under your service.
Hive = HKEY_LOCAL_MACHINE
Key = SYSTEM\CurrentControlSet\Services\<servicename>
Value = Description
Type = REG_SZ
Supply the text you want for the descripiton.
|
|
|
|
|
|
Here's how I do it.
SERVICE_DESCRIPTION Descr = {(LPSTR)GetServiceDescription()};
ChangeServiceConfig2(schService, SERVICE_CONFIG_DESCRIPTION, &Descr);

Hi
Im in a fix regarding accessing the flexgrid control of my dialog.
Im calling my dll(MFC) through an exe. In the dll there is a dialog that contains the FlexGrid. on calling of the dll the dialog box gets called. now i want to populate the grid with some data but im unable to access the flexgrid. On accessing the method of the grid it is showing Assertion error.
I know there are gurus in VC++ and hope you will assist me or give me any pointers.
Your help is greatly appreciated.

How can I detect when the ALT key is pressed and no other key is pressed? I wanted to change my cursor when the ALT is pressed. So i wanted to know which message is sent in this case.
Thanks

Try with WM_SYSKEYDOWN

It works only if i press a key followed by ALT. I want an event which fires when i press just the ALT key .
|
|
|
|

Is GetAsyncKeyState() of any help?
"Ideas are a dime a dozen. People who put them into action are priceless." - Unknown

|
|
|
|
Yes i am using it get the state of the ALT key but the point is I want to change my cursor as soon as the user presses the ALT key so for that i would require an event being fired or Currently i am using a timer which uses GetAsyncKeyState() to get the state and then i change the app cursor.
Thanks
