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.

Hi David,

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 ?

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

not working

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,

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.

Well, creating a DLL is quite simple, on the other hand, putting it into orbit is a rather complex task. Roll eyes | :rolleyes:

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.

Hi All,

How to split the CString in MFC?
My clode is:

CString str;
str = "READ rd659885676R8667U7788";

I need to split the CString with " "(space). That is i need "READ" in one variable and "rd659885676R8667U7788" in another variable.

Please help me.........

Hi Anitha,

You can use this code:

void
CSplit::Split(CString str, CString separator, CStringArray& array)
{
CString aux;
int pos;

pos = 0;
array.RemoveAll();
for (int i=0; i<str.getlength();> {
if (str[i]==separator)
{
aux = str.Mid(pos,(i-pos));
pos = i+1;
array.Add(aux);
}
}
aux = str.Mid(pos,str.GetLength()-pos);
array.Add(aux);
}

Regards,
Gustavo

Using DC in added class (outside CView class)

AglaiaMasaki23-Feb-09 1:57

Hello.

I can use CClientDC and its TextOut function in C~~View class.
It's quite simple like this:

void C~~View::OnLButtonDown(UINT nFlags, CPoint point)
{
CClientDC dc(this);
dc.TextOut(x, y, "..");
}

Yet when I use this function in my 'added' class, which is not derived class of CView,
an error occurs.
like this:

void CMyclass::memfunc()
{
CClientDC dc(this);
dc.TextOut(x, y, "..");
}

So I changed the code like this:

  [C~~View.cpp]
void C~~View::OnLButtonDown(UINT nFlags, CPoint point)
{
CClientDC dc(this);
CMyclass myclass;
myclass.memfunc(dc);
}
  [CMyclass.cpp]
void CMyclass::memfunc(CClientDC dc)
{
dc.TextOut(x, y, "..");
}

And errors still occur.
Of course, I linked the header file of my class to C~~View.cpp.
I want to display Text or Images on window with code in 'my class'.
Please give me advice or ideas. Thank you.

May the sky bring you a full measure of health and prosperity.
