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);

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."));
}

Hi,
Thanks for your reply.I don't want the path of the executable file,i want the working station of that file(for ex: D:\Work\New Text Document.txt).
|
|
|
|
|
You want the name of the process which has the file opened?
|
|
|
|
|
What i want is if a file is opened from D:\work\New Text Document.txt ,i want to get the path as stated before not the process name notepad.exe or excel.exe or some thing.can you help me out in this.

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;

How does that even come close to being a helpful answer?

here i am suppose to create a queuing and statistics box.. showing how many task get queue or terminated if queue is full... i just don't have any idea how to do that part..
help!!

The code you've shown is full of syntax errors. Fix those, and make use of the <pre> tags to make it more readable.

ok leave the code ...i was able to make a working one in C#
just help me in how to make counter which can count how many get queued.. and to make a counter that would count any thing over the queue limit...which would be terminated
an example or reference would be nice
don't mind C++ answer since i just need the idea.. its simple but i can't just grasp that part
thanks for replying
