Hello Iain,
I tried that Viewport of Joseph Newcomer and I would say in the array I'm using consecutive integers as X coordinates like 1,2,3,4,...,n...so in SetWindowExt, which should be the interested method for re-scaling I guess, I use current last X value in the array for X coord and in the place of Y I use rect.bottom since Y values in the array are actually random with this formula:
myarray[i].y = (LONG)( (double)rand() / (RAND_MAX + 1) * (rect.bottom
- 1) + 1 );
(the array is fixed size to the whole window resolution width where when I add new value at the last place I rotate before the array to shift-left it).
The matter is if I set SetWindowExt with last myarray[myarray.size() - 1].x and rect.bottom, which would be reasonably the right way to set for rescale, produces an assertion error.
Using Newcomer's Viewport example I found on codeproject, i figured to set the origin at bottom right having axis going back to bottom-left and top-right it made me setting SetViewportOrg and SetWindowOrg respectively to 0,0 and rect.BottomRight() so it would start from bottom-right... and setting SetWindowExt to rect.Width() and
rect.Height() didn't produced any assertion errors but doesn't repaints rescaled graphic. You can see the two results here:

control minimized
http://img16.imageshack.us/img16/4699/64174798.jpg <---- this is the
control maximized
Maybe I haven't got well in my mind about right settings of those
SetWindowOrg, SetWindowExt, SetViewportOrg, SetViewportExt...
Any suggest?...
Thanks
Ciao,
Luigi

please any one tell can we connect can we connect win32 socket in client side with CSocket class in server side????
if u give answer with sample code means i will be more happy..

Yes, at the network level there is only one type of socket, and a CSocket is merely a C++ wrapper class for the basic socket mechanism.

Unfortunately, you are going to be less happy. If you want source code you need to search the articles for samples; there are many.

There is no particular requirement on the Win32 socket connection, if in the other side there is a CSocket.
So just have a look at the documentation [^].

Sure. A socket is totally ignorant of what language dll is on top of it.
You could connect one end in VB to another in Java.

Yes you we can.

I would not use the class CSocket instead use CAsyncSocket or something else. Have a look at Beej's guide to networking programming[^] and Winsock Programmer's FAQ[^], there are client/server examples in section 6. You can download, modify it and play with it.
Hope it helps!

To get disk number for any drive i open drive (like \\.\c and pass its handle with IOCTL_STORAGE_GET_DEVICE_NUMBER in DeviceIoControl and get data in STORAGE_DEVICE_NUMBER structure. This structure returns the device number and partition number.
This works perfectly on basic disk but when i use the same on dynamic disk then it's fail.
Please suggest how to get disk number and partition number for dynamic disk.
|
|
|
|
|
u can try with this IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS structure.
it gives pratition number.
like this,
VOLUME_DISK_EXTENTS pdg;
....
DeviceIoControl(...,IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS,...);
....
pdg.Extents->DiskNumber;
thats it.

Srinivas

Thanks
After using that i get correct disk number. But i found starting offset and extent length different.It shows very large value for starting offset.And extent length shows a value(0x7e00) which is the position in disk from where this partition start.
Does extentlength means total size of drive or position of drive in disk?
typedef struct _DISK_EXTENT {
DWORD DiskNumber;
LARGE_INTEGER StartingOffset;
LARGE_INTEGER ExtentLength;
} DISK_EXTENT, *PDISK_EXTENT;
typedef struct _VOLUME_DISK_EXTENTS {
DWORD NumberOfDiskExtents;
DISK_EXTENT Extents[1];
} VOLUME_DISK_EXTENTS, *PVOLUME_DISK_EXTENTS;
|
|
|
|
|
u can get size of disk like this,
ULONGLONG ulLength = pdg.Extents->ExtentLength.QuadPart;

Srinivas

I have two doubts regarding ur question
1. If DeviceIoControl API is failing, can you check error with GetLastError API([^]).
2. What type of dynamic device you are using and hope it comes in one of the define type([^])

Hi all,
I have made a simple Dialog box application, in that i have made a static text control with Client Edge properties true and i also have a picture control which has a bitmap. That picture control is below that static control to give a look that bitmap inside that static control border. but the problem is sometimes that bitmap is not displayed i have also used Invalidate(False) everytime i have displayed both the controls but sometimes only static box is displayed and picture is not displayed...
How can i show it..
thanks in advance

May be you have to properly set the tab order. You can press Ctrl + D on resource view of dialog and see/modify tab order.
|
|
|
|
|
Static control tab should be first or picture control tab
|
|
|
|
|
I think static control should come before the picture box in tab order. I mean if static control's tab order is 1 then picture control's has to be 2.
|

still not visible sometimes....

Have a look at this: Overlapping Controls Are Not Supported by Windows[^] (means siblings). If you want overlapping controls in a dialog use a child-parent-hierarchy, for example use SetParent()[^]. Another alternative would be modifying the static text control you mentioned, make it a custom control that draws a picture in the background.
Hope this helps.
|
|
|
|
|
How do you hide the picture box? Are you using ShowWindow() for that?
|
|
|
|
|
In addition to what Moak mentioned, another thing I would suggest (as an easy workaround) is to remove the static control and enable Client Edge style for picture box.
