Hi,
The following code is not giving expected result for me.
I need display resolutions from the current monitor settings not from display device.
Problem is dispCurrent.DeviceName is not taken by the EnumDisplaySettings API.
Please tell me where i am going wrong.
int displayNumber=0;
DISPLAY_DEVICE dispDev, dispCurrent;
memset(&dispDev, 0, sizeof(dispDev));
memset(&dispCurrent, 0, sizeof(dispCurrent));
dispDev.cb = sizeof(DISPLAY_DEVICE);
dispCurrent.cb = sizeof(DISPLAY_DEVICE);
EnumDisplayDevices(NULL, displayNumber, &dispDev, 0);
while (EnumDisplayDevices(dispDev.DeviceName,displayNumber,&dispCurrent,0))
{
displayNumber++;
CString MonName = dispCurrent.DeviceName;
if ( (dispCurrent.StateFlags & DISPLAY_DEVICE_ATTACHED_TO_DESKTOP) == DISPLAY_DEVICE_ATTACHED_TO_DESKTOP)
{
// Get all modes and display them in a listbox
BOOL bRetVal;
CString sDevMode;
CString sDevModeCurr;
CString strRep = "x";
DEVMODE devmode;
DEVMODE devmodeCurr;
DWORD iMode =0;
do
{
bRetVal = EnumDisplaySettings((LPCTSTR)dispCurrent.DeviceName, iMode, &devmode);
iMode++;
if (bRetVal)
{
sDevMode.Format("%dx%d, %d bits %dhtz", devmode.dmPelsWidth,
devmode.dmPelsHeight, devmode.dmBitsPerPel,
devmode.dmDisplayFrequency);
m_sDispRes.AddString(sDevMode);
}
}
while(bRetVal);
}
}

Does anybody know if there is an auto build increaser in VC8? If so where and how is it configured?
In VC6 I used an add-in, but surely MS have updated a little since the dark ages.

Hi,
Sender:
- Establish Connection
- Send info what you're going to do, eg. copy file
- Open file
- read content
- send content
- close file
- Wait for acknowledge
- Shutdown transmission
- Liu out!
Recipient:
- Establish Connection
- wait for info
- create file (from info)
- receive content
- write content to file
- close file
- acknowledge completion
- Shutdown connection
Regards

Also, if using Windows Sockets, you can use the TransmitFile() API to do the "read content/send
content" steps mentioned by Galatei

Hi,
GetItemState(
int nItem,
UINT nMask

Hi,
The easiest way is to use GetNextItem:
INT nItemIndex = GetNextItem(
-1,
LVNI_ALL | LVNI_SELECTED
);

Hi, I am making one application in VC++.NT using WIN32 APIs. Is there any way to find which edit box has a keyboard focus right now using WIN32 APIs? I need handle of the edit box when some one type in that edit box. Thanks in advance. Priyank.

GetFocus(); to get the window that has focus, then use GetClassName or IsKindOf to find out whether the window is a CEdit.
|
|
|
|

thanks for your reply. But I can use GetFocus(); only if that edit control is in the same application. but I want to get handle of edit control that is in another application. Is it possible?

GetFocus returns the window with the keyboard focus for the current thread's message queue. If GetFocus returns NULL, another thread's queue may be attached to a window that has the keyboard focus.
Use the GetForegroundWindow function to retrieve the handle to the window with which the user is currently working. You can associate your thread's message queue with the windows owned by another thread by using the AttachThreadInput function.

Your code can reside within a DLL (Global hook) in this case.

Hello, Nice to meet you.
I'd like to know how to check the state of the tray with program.
When we push the button of CD drive, its tray operates like a toggle switch.
If now it was open, then it will be closed.
And it was close, then it will be opened.
Please help me~~~

Hi,
IIRC it could be done with use of DeviceIoControl with IOCTL_STORAGE_CHECK_VERIFY and IOCTL_STORAGE_EJECT_MEDIA functions.
Anyway, you should find some information about it in DeviceIoControl function reference and its related articles.

Try mciSendCommand. I remember doing it sometime back, don't remember exactly how I did it.

Thanks for giving a reply, but I already know MCI command.
What I want is how to detect the state of which the tray is open or close whether there is a CD in the tray.
I also tried the method using MCI command, but the method was restricted because could check the state only there is a CD in the tray.
Please help me in detail as possible~~~

Hi
In MSDN:
MapUserPhysicalPages:
The MapUserPhysicalPages function maps previously allocated physical memory pages at a specified address in an Address Windowing Extensions (AWE) region
AllocateUserPhysicalPages:
The AllocateUserPhysicalPages function allocates physical memory pages to be mapped and unmapped within any Address Windowing Extensions (AWE) region of a specified process.
So sorry for this question but i really don't know what is the difference between "allocating" and "mapping" memory.
Until now i supposed that they have same meaning but i think this is not true.
Can you please tell me what do these word indicate in win32 jargon?

To "map", "something" should already present. That can be done by "allocation".

Thanks but still i don't understand it.
Please a little more detail.

Does mapping mean:
Translate (from realtive to physical or physical to relative)?
Matching?
or directing?
Which one? or none of them?
|

Well, in general terms mapping memory pages means that you assign them memory. This is usually done by the operating system, since different processes have independent address spaces wich reside in the same physical memory. So memory of two different processes can be mapped to the same physical memory (of course that requires some complex administration eg. swapping pages etc.). So if you allocate memory it means, that your process declares to the OS that it wants some memory. Some free memory within your process adress space is then mapped to some free physical memory by the OS. The OS guarantees that you can use that memory as if you owned it exclusively, wich is not necessarily the case. Now you can map that memory again to some Address Windowing Extension, wich means you tell the extension "here's some memory you can use", but you are still the owner of that memory.
Long story short - allocate means to tell the OS you need memory - mapping means to map (e.g. virtual addresses of your process's address space) adresses to other (e.g. physical addresses of your machine) addresses. I have no clue whatsoever on AWE, but i think the idea should be the same. This may not be what you wanted, and it may not be complete, but i think it describes the idea.
Hope that helps a little.
