These are created in the CMainFrame::OnCreate function.
Just comment out the stuff you dont need.

My way is hide them.
For the toolbar, in the
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
add this line at the end:
m_wndToolBar.ShowWindow(SW_HIDE);
for the statusbar, I have not tried yet. Maybe similar to that.

Hello everyone,
I have a prebuild step which needs the following command/parameters....
IncBuild gpi.rc VS_VERSION_INFO$(_GPI6800)
However, Dev studio wants to use the $(_GPI6800) as a macro substitution rather than directly as I typed it in.
Anyone have any idea how I stop the subtitution?
TIA
James

Have you tried to just enclose it in quotes? Maybe escaped quotes (i.e. prepended by a backslash)?
If that won't work, you might consider replacing the dollar sign with something that isn't a documented macro initiation character.
|
|
|
|
|
Not sure this will work (as I have never used prebuild), but you could create a *.bat file with the command and call the bat file from prebuild.

Hello
My WINNT application crashes at startup.
I use quite a few threads in the program. It normally happens when there is data coming in at the Asynch comm port. When i disconnect the comm cable then there in NO crash at startup.
The DR Watson message says, "Access voilation : 0xc000005, Address : 0x0000080.
When I look in the Map file of the Released version, the address mentioned can only be found around :
comct132:COMCTL32.dll
0002:00000080 _imp_ImageList_ReplaceIcon@12 00476080
Does anyone perhaps know how I should continue from here to find the problem.
Thanks
Louis

Sounds like the rx thread is receiving data before other threads have started up, perhaps expecting some processing done by other threads which doesnt get done?
Can you delay that thread until all the others have started, or at least all initialisation is complete?

Thanks James
Adding a delay, thus waiting for all threads to startup solved the crash problem at startup.
Thanks again for your input.
Cheers

I build an interface splitted in two view : a CTreeView (at left) and a CScrollView (right) where i can draw chronogramms.
when i select a HTREEITEM , i want to draw a chronogramm which depends on the HTREEITEM.
The problem is that i need to move the splitbar to refresh the CScrollview after having selected the HTREEITEM to have my new chronogramm...
I use the OnDraw function in my ScrollView in which i call "Trace" function which draw chronogramms.
If u could help me.....ty
Sorry for my english i am french

Call RedrawWindow() on your CScrollView object when you get a TVN_SELCHANGED in your CTreeView window.
|
|
|
|
|
I need to insert OnSelchanged(NMHDR* pNMHDR, LRESULT* pResult) function in my CTreeView ?? function create when i add a windows message handler for TVN_SELCHANGED
where can i find the RedrawWindow() function ??
|
|
|
|
|
I normaly dont program MFC (just Win32 for me). But if the wizard dont add a OnSelchanged you will have to add it your self. And in that function call RedrawWindow() which is a member of CWnd which CScrollView inherits from.
|
|
|
|
|
ok it is what i do but it does not work...
the RedrawWindow(); function redraws which view ?? not my scrollview...
i want thats that when an HTREEITEM is selected, my ScrollView will be updated...
|
|
|
|
|
RedrawWindow redraws the window its called on.
CScrollView scrollViewObj;
scrollViewObj.RedrawWindow();
You ofcourse already have an object of CScrollView, call RedrawWindow() on that object and it should work. If that dont work, your WM_PAINT is probably implemented wrong.

I'm trying to display a dialog box with two tabs. When the dialog displays it shows the tab control and the child dialog for the first tab ok. When I click on the second tab the child dialog disappears but the new child dialog does not appear. Clicking on the first tab again has no effect. So the initial display is ok but clicking on a tab causes the tab contents to disappear. The code i'm using is:

Shouldn't the dialog templates have the WS_VISIBLE style?
|

I would like to get the type of control (Combobox, Button etc.) at runtime by the CtrlId to use it in a loop of all controls of a Dialog.
Is there a possibility?
I tried for example
pWnd->GetDlgItem(pWnd->GetDlgCtrlID());
CRuntimeClass *RuntimeClass;
RuntimeClass = pWnd->GetRuntimeClass();
But the Return of GetRuntimeClass was always "CTempWnd"
Does anyone know a solution. I think it must be simple if you know it.
Thanks.

That's... weird 
Use:
TCHAR szClassName[200];
::GetClassName(GetDlgItem(IDC_OF_CONTROL)->m_hWnd,
szClassName, 200);
rechi

|

int GetClassName(
HWND hWnd, // handle of window
LPTSTR lpClassName, // address of buffer for class name
int nMaxCount // size of buffer, in characters
);
pWnd->GetDlgItem(pWnd->GetDlgCtrlID());
::GetClassName( pWnd->GetSafeHwnd(), sClassName.GetBuffer(64), 64);
sClassName.ReleaseBuffer();
sClassName == "EDIT", "LIST", "BUTTON" etc

What if the window does not belong to your application?
Suppose I only have a Handle to another Window running on the system, how do you GetDlgItem for such a situation?
Thanks,

I'd like to pass a string from an app to another using a user-defined message and SendMessageI'm receving the message but when i typecast wParam, I do not get my string but "IIIIIIIII...III" even if types and memory address match in both application when debugging.
What's wrong ?
