Dear All,
I am working on VC++ and developing a tool for Weather monitoring system.
Here I am facing problem in displaying different views for same dateset from the document class, where all the calculations are take place.
Here I am using SDI Multiple views architecture.All (Two) views are controlled by the menu and they are switching fine.
At this moment only one view is connected to the document and displaying the date.Second view is not updating the data implicitly.
Please suggest me an idea to update the data to both views concurrently.
Thanks in Adavance

use Invalidate() or an user defined PostMessage to inform the view to redraw.

Hi KarstenK,
Thanks for your prompt reply and valuable suggestion.
I did try with Invalidate().
I have wrote code as follows
/ / This is View1 connected to the document with
void CStringView::OnDraw(CDC* pDC)
{
CPoemDoc* pDoc = GetDocument();
pDoc->UpdateAllViews(NULL);
}
//This is View2 to be updated
void CHexView::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint)
{
// TODO: Add your specialized code here and/or call the base class
Invalidate();
}
But it is not triggering OnDraw() of CHexView().
I do not have any idea about user defined PostMessage to redraw.
Please give me some idea to move on...
Thanks
Madhu K

are you shure that CHexView::OnUpdate() got called.
use RegisterMessage() to get a valid message id and use PostMessage() to send it to your CHexView-Window.
Write a message handler
Read the msdn or google for the bold stuff

I am getting an error like
ExceptionAttacher.obj : error LNK2019: unresolved external symbol "int __cdecl RecordExceptionInfo(struct _EXCEPTION_POINTERS *,char const *)" (?RecordExceptionInfo@@YAHPAU_EXCEPTION_POINTERS@@PBD@Z) referenced in function "int __stdcall AfxWinMain(struct HINSTANCE__ *,struct HINSTANCE__ *,wchar_t *,int)" (?AfxWinMain@@YGHPAUHINSTANCE__@@0PA_WH@Z)
What should I do to remove this linker error? Plz help me.
Thanks

where is this function defined? A linker error usually means that the compiler is unable to find the definition of the function. You may need to specify the library for it under the linker settings.
You need to google first, if you have "It's urgent please" mentioned in your question.

this function is defined in a file named ExceptionHandler.cpp .
I am not getting that what to do to remove this linker error?
Plz provide any solution if possible. Thank You.

are you sure this function is defined and declared and you have included the header file for this class.

Why obviously ? Seing your error and the fact that you are sure that you have a body for your function, then I would say that it is obvious that the file is not added to your project.
I am talking here about the cpp file, not the h file. How did you add this file to your project ?
Can you also post the function prototye (which is in the header file) and the function body (which is in the cpp file) ? Please use the code tag to format the code properly when posting.

The underlined bits have been added.
Note that if you're building for Unicode then the first is an ANSI string and the second is Unicode and so the second in NOT the definition of the first.

The arguments of the function prototype do not match the arguments of the function definition if UNICODE is defined (in which case, LPCTSTR will resolve to a wchar string, and not a char string). So, replace the char in the function prototype by the same LPCTSTR and this should fix your problem.

thanks, I have removed this error.

The error message seems to be saying:
A function with the signature int __cdecl RecordExceptionInfo(struct _EXCEPTION_POINTERS *,char const *) is referenced in the file "ExceptionAttacher.???" from the function int __stdcall AfxWinMain(struct HINSTANCE__ *,struct HINSTANCE__ *,wchar_t *,int). Clearly the function int __cdecl RecordExceptionInfo(struct _EXCEPTION_POINTERS *,char const *) is declared or we would have a compiler error instead, but it's not defined or the file it's defined in is not included in the project because the linker can't find it.
PS: Why the function AfxWinMain defined in "ExceptionAttacher.xxx"? This function is part of the MFC framework and not meant to be user defined.

Under dialog properties set the System Menu to false.
You need to google first, if you have "It's urgent please" mentioned in your question.

Hi out there-
I have a UNC path \\192.168.0.100\share and would like to convert it to the network name. i.e. \\SERVER\share
WNetGetUniversalName doesn't like it and is reporting "The specified device name is invalid".
Is there an easy way to deal with this?
