Hi
I am facing problem in accessing the function template written inside a class. My code is as follows.
Please help me in this regard.
mytemp.h
class mytemp
{
public:
mytemp(void);
~mytemp(void);
template<typename t="">
static T templateadd(T x, T y);
};
mytemp.cpp
template <typename t="">
T mytemp::templateadd(T x, T y) {
return (x + y);
}
main.cpp
int _tmain(int argc, _TCHAR* argv[])
{
cout<<mytemp::templateadd(10,2); // Here I am getting error: unresolved external symbol ...
//Here I want to access templatedadd() of mytemp class. Please tell me What should be the statement.
return 0;
}

This is a subtle problem with templates, there's an explanation ahy it happens in here[^]

I have an application created with VS2005, consisting of some com-components created with VS2005. But one of the components is created by another department, so this component is still created with VS6. To find an error i have to debug from my application (VS2005) into this semi-external component(VS6). I have the symbols (.pdb) and the source files for the component and i succeed in stepping into the code of the component. But i can't watch any symbol. Has the PDB-format changed between this studio versions, are there any tricks to do the thing ?

Hi,
I want to change radio button while my program is running.
It start with normal radio button, but a want to change it while running so the text would be on the left side and the button on the right.
(It would look like radio button with "Left Text = true" when u click the button properties.)
I tried
CButton* button = GetDlgItem(IDC_RADIO1)
button->SetButtonStyle(BS_LEFTTEXT)
button->SetButtonStyle(BS_AUTORADIOBUTTON | BS_LEFTTEXT)
and few more but i failed.
Any idea ?

That isnt a good idea because it confuses a lot of users. Better rethink the design.
(if you really want to confuse the user, use 2 Buttons with one invisible and change the visibility)

Yes,
HWND hWndRadio = ::GetDlgItem(this->m_hWnd, IDC_RADIO1);
LONG lStyle = GetWindowLong(hWndRadio, GWL_STYLE);
lStyle |= BS_LEFTTEXT;
SetWindowLong(hWndRadio, GWL_STYLE, lStyle);
::InvalidateRect(hWndRadio, NULL, TRUE);
::UpdateWindow(hWndRadio);

I want to use of your code freely?

char str[8];
cin >> str;
When run, if inputed string size more than eight byte, result run time error.
So, how to limit cin >> size or only get eight byte when inputed more than eight?
thanks!
|

allocate memory dynamically based on the size of the string
You can use a loop (upto 8) along with getch()/getchar() to get the user input
Some things seem HARD to do, until we know how to do them.

cin statement doesn't provide you with limited input support. since it wait for RETRUN/ENTER key for updating the input character in buffer supplied to it.!

std::cin.get(str, sizeof(str), '\n');
or
std::cin >> std::setw(sizeof(str)) >>str;

Were you expecting a different result? Why not use a string object instead?

Hi Experts,
How can I import .rtf or .doc file content into TextBox.
|
|
|
|
|
Could anybody give reply?
|
|
|
|
|
For import doc file use rich edit control instead of edit control.
|
|
|
|
|
If you were using a rich edit control instead, you could just stream the data in.

you can't find the name of file if you have window/FILE handle.

If you are asking how to get the filename of an executable by knowing a window handle then this is how you do it. This code will tell you the PID of the executable even if you pass a child handle such as a button handle.
#pragma comment(lib, "psapi")
DWORD dwPID = -1;
BOOL CALLBACK EnumChildWindowsProc(HWND hWnd, LPARAM lParam)
{
if(hWnd == (HWND)lParam)
{
GetWindowThreadProcessId(hWnd,&dwPID);
}
return TRUE;
}
BOOL CALLBACK EnumWindowsProc(HWND hWnd, LPARAM lParam)
{
if(hWnd == (HWND)lParam)
{
GetWindowThreadProcessId(hWnd,&dwPID);
}
else
{
EnumChildWindows(hWnd,EnumChildWindowsProc,lParam);
}
return TRUE;
}
BOOL FindWindowProcessModule(HWND Hwnd, TCHAR *szName,size_t iMaxLen)
{
EnumWindows(EnumWindowsProc,(LPARAM)Hwnd);
if(-1 != dwPID)
{
HMODULE hModule = NULL;
DWORD dwNeeded = NULL;
HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ,FALSE,dwPID);
if (NULL != hProcess)
{
if(EnumProcessModules(hProcess,&hModule,sizeof(hModule),&dwNeeded))
{
GetModuleFileNameEx(hProcess,hModule,szName,iMaxLen);
}
else
{
GetProcessImageFileName(hProcess,szName,iMaxLen);
}
CloseHandle(hProcess);
}
}
return NULL != szName[0];
}
Here is how you would use it:
TCHAR szName[MAX_PATH] = {0};
HWND Hwnd = (HWND)::FindWindow(_T("SciCalc"),_T("Calculator"));
if(FindWindowProcessModule(Hwnd,szName,MAX_PATH))
{
MessageBox(szName);
}
else
{
MessageBox(_T("Calculator is not running."));
}

You can use function _getcwd(char* buffer,int maxlen) which will give you current directory. I hope this is you are looking for.Following simple code shows you how to use it.
char* buff,buffer[255];
buff = _getcwd(NULL,0);
cout<<buff<<endl;
