Hi all,
I am creating an application for windows Vista, XP and 2003Server. In my application I need to create and format partitions(Extended and primary both). I do not want to use DISKPART utility. Is there any other way to do this job like by using any win32API or any function provided by Microsoft in MSDN?

Please give me some suggestions.

Thanks

Ya ofCourse, you can use DeviceIoControl codes. for creating any partition (primary or logical) IOCTL_DISK_SET_DRIVE_LAYOUT can be used. Big Grin | :-D

Thanks CMylife.

I am going to implement it now. I will consult you after trying it.

Its good that you are trying yourself. nothing you have to do. u first of all get the all partitions information by using IOCTL_DISK_GET_DRIVE_LAYOUT, then just edit the partition number, its offset, size and the last parameter , set that to true and finally run the IOCTL_DISK_SET_DRIVE_LAYOUT code from there itself. and then you are done with a new partition.

All the best.

Thanks CMyLife.
I am not sure that you will get my query today coz this thread is of one day old.
I have successfully created the partition using IOCTL_DISK_SET_DRIVE_LAYOUT. But now I am stuck in formatting this raw partition.
There is one function FormatEx() but it is only for Vista. Is there any other way to format partition without using DISKPART and SHFormatDrive like some ioctl code.

Thanks

google for FMIFS.h and FMIFS.dll to format any volume.

Create CBitmap from array of RGB values

I want to create a CBitmap which I can them put inside an image list. Now I have the width, height and an array of RGB values. How can I create a valid CBitmap object from that?

Create an hidden CDC, attach the bitmap to it then use CDC::SetPixel for example
There is also CBitmap::SetBitmapBits

Hi, Russell

Thanks for replying. CDC::SetPixel would be too slow for me, I need to make thumbnails of potentially many files. CBitmap::SetBitmapBits doesn't seem to accept width/height in the params.

According to my VS2008 MSDN, SetDIBits[^] should be used in preference to SetBitmapBits. SetDIBits allows you to specify the bitmap size, I believe.

use SetCursor api! read more about it in MSDN documentation

See SetCursor[^]

You need to google first, if you have "It's urgent please" mentioned in your question.

First you have to create the cursor using the resource editor using your drawing skills.

Use the following APIs.

First load the required cursor using either.
1) LoadCursor(NULL, IDC_ARROW);//User for arrow cursor
2) HCURSOR LoadCursorFromFile( LPCTSTR lpFileName); //Give the name of the .CUR file (Pen cursor file)as parameter.

Both these functions return HCURSOR.
Then set this cursor using API.

HCURSOR SetCursor(HCURSOR hCursor);

About data combination

There are n arrays, and there are several elements in each.
Count of array and count of elements in array are variable.

A1{a1,a2,a3,an1} //there are n1 elements in array A1
B1{b1,b2,b4,bn2} //there are n2 elements in array B1
.....
N1{n1..nn} Confused | :confused:

//there are n elements in array N1

I need all the combination which are composed with one element of every array,order is same as the array's
like:
a1,b1,.....n1
a1,b2,.....n2
...
a2,b1,.....n1
...
an1,bn2,....nn

what about stl::Vector, you can use like this :-

#include&lt;vector&gt;
using namespace std;
typedef vector<int> vecINT;
typedef vector<vecINT> vecINTINT;


vecINTINT  vecArrays;
vecINT		vecA;

//insert your element of array 
vecA = A1{a1,a2,a3,an1} //there are n1 elements in array A1

// and copy it to main array
a.push_back(vecA);

Thank you very much for your reply, but I am not quite clear about it. Would please explain it in detail? I need a algorithm to get all the combinations.

You've just to write a loop for each array (and nest the loops) is it difficult?
You may also use recursion.

recusion, sometimes it's quite difficult even for seasoned programmer. Though, recursion is good programming practice, come handy when you travelling through tree like data structure.. but it's a pain when you have to debug it Smile | :)

Because the count of array is variable, it is difficult to use loop. Recursion is good idea, but would you please write some sample code for me? thank u!! Rose | [Rose]
