Hi all,

I'm a bit lost. The thing is how can I change the appearance of the main window after I have chosen a Win32 Application Project - Simple Hello World Confused | :confused:

(I'm use to CLI VS2K5)

Can you explain in detail ?

Ok,

So you open VS 6 C++.
You choose a new project and you choose a Win32 Application.
It brings up a small dialog asking things like "empty project" | "Hallo World".
So I chose the "Hallo World" one.
The complier builds a couple of resources cpp files, header files and so on.
The thing is how can I change that main window that the compiler created. It looks like everything was created using code by the compiler. Cause the createWnd function was used and so on.

Makes sense?

You need to look in to WM_PAINT, in WndProc function, that is where painting operation occurs.

Or I've misinterpreted again !

You need to handle this in WM_CREATE message.
Add this code to your WndProc in switch statement.

case WM_CREATE:
{
  HWND HwND = CreateWindow("BUTTON","My Button", WS_CHILD |
  WS_VISIBLE | BS_PUSHBUTTON , 20,20, 50,50,hWnd,(HMENU)    ID_BUTTON1,hInst,NULL);
  ShowWindow(HwND,SW_SHOW);
 } //ID_BUTTON1 is unique identifier

Thnx Prasad...

And you have to do it for each component you would like to add? Isn't there an easier way?

Nope .
Thats why MFC comes up.

Re: linker error for library

13-Dec-06 0:58

Hi all,

Take the follwoing into consideration:

vector<string> getSecNameString = CIniFile::GetSectionNames(FileName);
for(int i=0; i < (int)getSecNameString.size(); i++)
{
    cout << "\n** Section Name ** -> " << getSecNameString[i].c_str() << endl;
    vector<CIniFile::Record> getSecString = CIniFile::GetSection(getSecNameString[i], FileName);
    printf("\n.... GetSection Keys & Values ..... \n");
    printf("--------------------------------------\n");
    for(int i=0; i < (int)getSecString.size(); i++)
        cout << getSecString[i].Key.c_str() << "=" << getSecString[i].Value << endl;
}

The output would look someting like this:

[Section A]
keyA=1
keyB=2
{Section B]
keyC=3
keyD=4

O.k so now one wants to put each of these values into labels and textboxes.
For example the following must happen (Non-visual example):
label1 -> keyA
textBox1 -> 1
label2 -> keyB
textBox1 -> 2
and so on...
Please note that one would not know the limit of each section or key, and don't mind the "[]"

Thanx in advance

Hi,

i have developed .lib for logger from opensource called log4cxxx.
they have given samples to use the .lib file. while i am using functions (which are implemented in .lib) with string parameters got link error

rror LNK2001: unresolved external symbol "public: void __thiscall log4cxx::Logger::debug(class std::basic_string<char,struct std::char_traits<char="">,class std::allocator<char> > const &,char const *,int)" (?debug@Logger@log4cxx@@QAEXAB
V?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@PBDH@Z)
../Bin/Static Debug/trivial.exe : fatal error LNK1120: 1 unresolved externals

where as i didn't get any error for functions with integers.

function protype

void Logger::debug(const String& message,const char* file=0, int line=-1);

i am using

const char *file1="log.txt";
debug("debug info",file1,100);

can anyone help on this issue.i am using vc6.0.

advance thanks

Please go through the function prototype again. There may be some mismatch.

If that is OK then try to link the libray as following preprocesser directive.
#pragma comment(lib,"full path of library")
put above line in .cpp file below the header includes

Hi everyone,
Maybe my question is funny but I want to know what is it?

CMap<UINT,UINT,UINT,UINT> Map;Map m_Map;or CList <int> m;
or typedef CMap<UINT,UINT,UINT,UINT> m_Map;I know that typedef declare a new kind of an exist kind

Hi thanks for your help
I want to know what is it CMap<> or CList<>

This means that, these classes requires templete arguments.

Sorry I ask again I have another question can you explain for me For example what is it CMap<int,int,int> Map; Map m;
thank you prasad_som

prasad_som13-Dec-06 19:34

13-Dec-06 19:34

Possibly you are asking, what is

typedef CMap<UINT,UINT,UINT,UINT> Map;
 Map m.

Because, what you have asked is not possible.

Its used just to increase redability.

When we must use of this case of course I know its depends to our program
I cant understand what is it typedef CMap<UINT,UINT,UINT,UINT> Map; Map m.

typedef

typedef is keyword for declaring synonym for type declarations.
i.e.
typedef char TCHAR;
Now, TCHAR
can be used instead of char.

messages wrote:

typedef CMap<UINT,UINT,UINT,UINT> Map;

This statement indicates Map is synonym of CMap<UINT,UINT,UINT,UINT> .So statement
Map m ; is actually CMap<UINT,UINT,UINT,UINT> m;
