Hi,
After clicking on "add new item" in Visual C++ .NET i choose "new form".
Now if i want a button to show the new form and close the current form what should i do ?
Thanx in advance,
Desmo16.

Double click the button to generate the handler for the button.
#include "TestForm.h" // change this to your form name(class)
// button1_Click place this code
TestForm *tForm=new TestForm ();
tForm->Show ();
this->Hide();
Somethings seem HARD to do, until we know how to do them.

How to change the property sheet back ground color?
Not property page.
|

No sweat.
Handle WM_CTLCOLOR in your CPropertySheet derived class and return the appropriate brush handle:
Example:
HBRUSH CMyPropertySheet::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CPropertySheet::OnCtlColor(pDC, pWnd, nCtlColor);
if(CTLCOLOR_DLG == nCtlColor)
{
CBrush brush(RGB(0,0,255));
hbr = brush;
brush.Detach();
}
return hbr;
}

I define a struct
struct TAlarmInfo
{
BYTE byType;
DWORD dwNodeID;
char szCenter[LEN_OBJNAME];
char szStation[LEN_OBJNAME];
char szDevice[LEN_OBJNAME];
char szDataItem[LEN_OBJNAME];
...
...
}
I build a client to receive alarm from server.When I receive an alarm.If I check it using char pointer
to access szDataItem,just like
p+5,It works well.But if I use a struct pointer,
struct TAlarmInfo *pAlarmInfo = (TAlarmInfo *)p;
pAlarmInfo->szDataItem,the value is not right.I check the value and find the pAlarmInfo->szDataItem position is past 3 byte off the correct position.
Why?thanks

certainly because of the compiler's bytes padding...
search the MSDN for #pragma pack/pop
BTW, pAlarmInfo->szDataItem is the right way to do it !

If p points to the beginning of the structure, then p+5 should not point to the szDataItem member. That indicates something is awry with the byte packing.

Hi,
I tried to add a CPP file with HPP file which contained one or more classes using Namespaces in my MFC SDI application.I got this error..
error:
C1010 unexpected end of file while looking for precompiled header directory.
But I added the same CPP file by creating a Empty Win32 Console Application where the application run successfully.
Help me..How to avoid this error.

|
|
Add the line
#include "stdafx.h"
at the top of this file.
Or you can also disable precompiled headers for this file (right-click on the file and go in the properties).

Hello can any one explain about the clip sibling property of any dialog,
and clip children property of dialog.
The macros are : WS_CLIPSIBLINGS, WS_CLIPCHILDREN
I could not understand where it is useful.
I want to know what is use of these two properties.
Thanks.

as far as I know, these window styles are not really related to dialogs but rather to generic windows such as controls, overlapped windows etc... both have to do with drawing windows to limit the amount of drawing that needs to be done in a particular window
WS_CLIPCHILDREN
Excludes the area occupied by child windows when drawing occurs within the parent window. This style is used when creating the parent window.
WS_CLIPSIBLINGS
Clips child windows relative to each other; that is, when a particular child window receives a WM_PAINT message, the WS_CLIPSIBLINGS style clips all other overlapping child windows out of the region of the child window to be updated. If WS_CLIPSIBLINGS is not specified and child windows overlap, it is possible, when drawing within the client area of a child window, to draw within the client area of a neighboring child window.
ClipSiblings is quite useful if you have child windows overlapping and you are custom drawing something inside of the window...it basically keeps you from drawing in to the wrong window

Hi to all,
I am using 'Windows Media Player' in VC++6 from 'Registered ActiveX Controls'. The code is working fine on my PC (Xp Professional). But when I run the exe on other PC, it is creating a problem.
On other Xp Professional, it shows an error message as "unhandle win32 exception occur in exe" & ask for debug.
While on Windows Server the exe is not ruuning.
What should i do? Plz. help me.
Best Regards & Thanks,

Has the ActiveX control been registered on the other machine(s)?

If not, then how to register it. (If possible explain in detail.)
|
|
|
|

regsvr32.exe comes to mind.

Have you looked for wmp.dll?

Hi,
Thanks for ur all previous useful suggestions.
But how to know ... which dll should be used for any ActiveX Control?
( e.g. which dll should be used for MS Flex Grid Control? )
Thanks & Best Regards,

That would be in msflxgrd.ocx.

Thanks.
But my que. was "How I can know which is the supporting file(s) for any (other) ActiveX Control?"
From where you come to know that,
msflxgrd.ocx : for MS Flex Grid AND
wmp.dll : for Windows MEdia Player
Best Regards,
Aniket
