I'm having somewhat of a strange problem. When overriding WM_NCACTIVATE to draw custom borders to my window, the window no longer becomes the foreground window. It has the focus, but is not the currently selected window within the Taskbar. A similar problem arrises when closing the window, the previous is neither selected or has the focus.
I have tried calling SetForegroundWindow() from various locations within the code, but it has no effect. A call to DefWindowProc() before my own code solves the problem, but creates others. Could anybody point in me in the right direction as to exactly which API call is required?

I feel so stupid sometimes  I tried it before, but I can't think why I didn't try the SWP_SHOWWINDOW flag. Thankyou.

What value are you returning from your WM_NCACTIVATE handler? The ret value is important for that message as it controls the active/inactive state of the window after the handler returns.

I should have read the docs a little more carefully. I was handling the WM_NCACTIVATE to get the required state for the borders then falling through to a WM_NCPAINT handler, which should return 0. My mistake.

Hi,
I am writing an application where I convert the set of images to .avi file. I am using use XviD MPEG4 codec as a default codec. I set this as default codec to “xvid”. Now my AVIStreamSetFormat function displays a dialog box with title "XviD Status". How can I avoid this dialog box?
Regards,
Hemant Kulkarni.

There's an option in the XviD Configuration dialog to turn it off.
Also, try this registry entry
HKCU\Software\GNU\XviD\display_status
Set it to 0.
(found this on google, don't know if it's right  )

Hi All,
I am new this VC++ Programming. Can one say that how to create a shared memory so that all process can access that memory?.
or let me know that where can i see shared memory programming articles?.
Thanks in Advance...
|

There are a couple of ways. One is to make an EXE or DLL that has a shared data segment. ie.
#pragma data_seg(".shared")
int g_SharedVariable = 1;
#pragma data_seg()
#pragma comment(linker, "/SECTION:.shared,rws")
Another way is to use the CreateFileMapping API with hFile set to INVALID_HANDLE_VALUE and dwMaximumSizeHigh and dwMaximumSizeLow set to the size of the mapping.

Hi All,
I've created a dialog based application with the dialog having multiple editboxes. What I want to achieve is to call a specific function when I press "Enter" key. Each editbox should trigger its specific function or I should be able to know from which editbox the enter key was pressed.
Please help.
Thanks,
Gajendra

Using this I can get a pointer to the ebox. If I could get the ID number of the ebox in context, it would help me more than having a pointer as my application logic depends on that.
Can you suggest something on obtaining focussed ebox control id number?

Gajendra

You can override default PreTranslateMessage function of the dialog/window class.
BOOL CBAMBuildToolDlg::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_KEYDOWN)
{
if(pMsg->wParam == VK_RETURN)
{
if (pMsg->hwnd == ::GetDlgItem(*this, IDC_EDITBOXID)
//Replace with proper ID
{
//Handling of the return key for this edit box
return TRUE;
}
}
}
return CDialog::PreTranslateMessage(pMsg);
}
I hope the above code snippet will help you.
Regards,
Stanly

from where this ID will come.. and are you going to check like this, for every Control present on Dilaog box.. this really going to make you PreTranslateMessage Bulky..

ID is the Editbox ID in the resource file. If you need to handle differently for each edit box in the dialog, you have to handle it seperately. Otherwise,
you can use one button as 'default' button and handle the event there.

then I believe his question wrong.. actually that person want currently focused EditBox at the Time of press of enter key

when you got pointer to Window you can easily call function GetDlgCtrlID to retrieve it control id

I have a program that is able to take the numbers out of the .txt if it is just a list of numbers. Problem is, I have a file with Names before the grades. I believe i need to set up another array inside the first one to fill with names. The .txt file will look like:
Name
grade
grade
grade
grade
grade
grade
grade
grade
grade
grade
Name
...
Have 15 Names with 10 grades under each. I guess what i'm trying to do is take the strings out of the file. Is there a way to take the strings(there is a string every 11 lines)
Here is what i have now:
#include
#include
#include
#include
#include
#include
using namespace std;
const int TESTS = 10;
const int STUDENTS = 15;
void displayGrades( int [][TESTS] );
void getGrades( int [][TESTS]);
int main()
{
int data[STUDENTS][TESTS] = {0};
getGrades( data );
cout <<fixed <<setprecision(1);
displaygrades(="" data);
#ifdef="" win32
system("pause");
#endif
return="" 0;
}
void="" getgrades(int="" data[]="" [tests])
{
ifstream="" inputfile;
inputfile.open("gradespring07.txt");
if="" (!inputfile)
{
cout="" <<="" "error="" opening="" file!"="" endl;
exit(="" 1="" );
}
for="" (int="" student="0;" student<="" students="" ;="" student++)
{
for="" test="0;" test
{
inputfile="">> data[student][test];
}
}
}
void displayGrades( int data[][TESTS] )
{
double testTotal = 0.0;
double classTotal = 0.0;
double squared = 0.0;
double var = 0.0;
double sdev = 0.0;
int mxm = data[0][0];
int min = data[0][0];
cout << "\nGrade summary" << endl;
cout << "--------------" << endl;
cout << left << setw(7) << "Student"
<< right << setw(5) << right << "Ex1"
<< setw(7) << "Ex2"

So what's your actual problem? Does it fail to compile? Does it crash? Does it just act weird?
Is there a particular part that you know isn't working properly? Have you tried stepping through that part in a debugger?
If you can isolate the particular part that's giving you a problem, let us know, and we might be able to help

there is no problem with the code that i posted. The problem i am facint is that the posted code will only read a list of integers without a student name. The .txt i need to read from is supposed to have the student name then 10 grades after then another name and another 10 grades. Don't know how to retrieve the name.
Thanks
