Thanks for the suggestions...they got me going in the right track....

Here is the resolution/what I ahve done now to implement what I set out to do....

Scenario is I have a Tabbed application, where each of the tabs are a CPropertyPage (reference: see Venura's Simple Tab Control)

and my objective was to run a member function of a Tab when a user clicks into the Tab

In the Tab's/PP's class add the handler
CPPTwo.h

afx_msg void OnWindowPosChanged(WINDOWPOS *pwp);

CPPTwo.cpp

//... under the event handler section add the Event Handler
BEGIN_MESSAGE_MAP(CPPTwo, CPropertyPage)
.
.
ON_WM_WINDOWPOSCHANGED()
.
.
END_MESSAGE_MAP()

Then add the member function

void CPPTwo::OnWindowPosChanged(WINDOWPOS *pwp)	
{
   //wincore.cpp calls this function if you enter OR leave the tab
   //This below if condition will run only if the tab is cicked in to i.e. Enter Tab
   if ((pwp->flags & SWP_SHOWWINDOW))
   {
      //The code you want to run each time you enter the tab
   }
}

msdn reference: WM_SHOWWINDOW Notification,
http://msdn.microsoft.com/en-us/library/ms632645.aspx
In this if you look under Community Content section you'll see Use WM_WINDOWPOSCHANGED to react to window state changes

read comma delimeted numbers and text mixture in a line [modified]

Hi

I would like to read each number (integer and float) and a word (e.g. E1) in between these numbers:

1,1,1,E1,0.13060,-0.40193,-0.90631
7,1,1,A25,0.13060,-0.40193,-0.90631

Using the statement:

char buffer[15];

for (i=0;i<2;i++)
{
fscanf(f_ptr1,"%i,%i,%i,%s,%f,%f,%f\n",&kdum[i],&nlinks[i],&ndih[i],buffer,&cos_xx[i],&cos_yy[i],&cos_zz[i]);
...
}

"buffer" should read only "E1", but it reads: "E1,0.13060,-0.40193,-0.90631"

I need:
kdum[0]= "1"
nlinks[0]="1"
ndih[0]="1"
buffer="E1"
cos_xx[0]="0.13060"
cos_yy[0]="-0.40193"
cos_zz[0]="-0.90631"

kdum[1]= "7"
nlinks[1]="1"
ndih[1]="1"
buffer="A25"
cos_xx[1]="0.13060"
cos_yy[1]="-0.40193"
cos_zz[1]="-0.90631"

Thanks for help

By default, reading a string using fscanf reads until the next whitespace (that'll be the EOL).

Either change the number of characters read for the string or change the string delimiter. This page of the documentation[^] gives the necessary details.

I can not change the delimiter. I have to read as they are.

No - change the delimiter that fscanf uses as denoting the end of the string. Did you read the documentation I pointed you at?

You'd be better off reading the whole line into a string buffer and then tokenizing it. If you can't go that route, then fscanf()'s format argument will need to change. It's easy to do, but very ugly and prone to error.

If you can give me some key code fragments for the tokenize, that would be a great help.
Thanks

strtok() (C)

AfxExtractSubString() (MFC)

CStringT::Tokenize() (MFC)

C++ does not have a formal string tokenizer, but it's very easy to create one using a vector to hold the tokens. You may also be able to do it via istringstream.

after tokenizing, how to convert char to float ?

ff = float(strtok(string, seps));

How to fix the Linking error

Hi,

I have tried to build a project which has written in vc++/MFC. The project last build with 7.10 version and I am trying to build it using VS.Net 2003 and VC++ compiler version 7.1.3088. When it reaches to the part "Linking" start throwing the following type of link errors,

error LNK2005: "private:_thiscall type_info::(classs type...
error LNK2005 _abort already defined in libcmtd.lib(dbgheap.obj)
etc

I am sure , no error is there with the program and it is compiling fine..I would really appreciate if anybody can show me the right way to resolve these type of errors.

Note: I have seen the existing project contains a file with ".odl" extension and I changed to ".idl" because I found while creating a new project it is creating ".idl".

Thanks In Advance.

That looks very much like you're linking your program against two versions of the C runtime library somewhere. The 'already defined in libcmtd.lib' bit gives it away.

Can you check that all projects in the solution have the same runtime library selected in the C/C++->'Code Generation' property page?

Hi Stuart Dootson,

Thanks much for your response. I have checked the runtime library and its same for all the projects. ("multi-threaded debug"(/Mtd)). One difference I found is that, some projects having Basic runtime checks as default and some having "both".

When I tried to rebuild each project separately, only one project was showing link error ...All other projects got rebuilded file.

Please let me know if you have any other suggestion.

Thanks,
Siju Thomas.

Since I couldn't find a way to solve the linking error, I have tried to create a new project and replaced the automatically created files and added the files from the existing project..when I build that it was able to link with out any Issues..It didn't throw any linking error.

But, I have got another error which is given below.

while debugging
"error PROJ0019: A tool returned an error code from "Performing Registration"

While manually resistering the ocx
" DLLRegister failed, Return code was: 0*80040200"

Any idea to resolve this?

Thanks,
Rahul.

In the properties of the DLL project, set the "No Entry Point" property in the advanced linker options to true.

1- double-click on the DSP (or is it DSW) file.
2- accept to convert the project files.
3- save
4- build-all
5- look at the errors/warning
6- google the error number
7- fix them.
8- goto 4

anyway ... most errors are due to new method/functions prototypes in MFC, and some deprecated C functions.
