I'm mixing GDI and GDI+ together a bit and attempting to create a region in GDI+, then use the handle to that region to invert the colors using ::InvertRgn in GDI using the same HDC used to create the graphics object but someone helped me discover that the region is in device units when used in GDI and world coordinates in GDI+.
I'm struggling with the fact that I'm using the GDI mapping modes for my scaling so when I use the handle from the GDI+ region in a GDI function, the scaling gets mucked up without manually reproducing the scaling effect.
My question is "Does anyone know how the same effect (InvertRgn) can be achieved in GDI+ using the graphics object that is backed by a memory DC"?

Hi all
i have an Embedded Visual C++ aplication, in this aplication
exist a class where have declare the const CLSID_SQLSERVERCE_2_0
for create instance OLE DB for SQL CE 2.0
CLSID_SQLSERVERCE_2_0 = {0x76A85B2E,0x9DE0,0x4ded,{0x8E,0x69,0x4D,0xEF,0xDB,0x9C,0x09,0x17}};
i found CLSID for SQL CE 3.0
CLSID_SQLSERVERCE_3_0 = {0x32ce2952, 0x2585, 0x49a6, {0xae, 0xff, 0x17, 0x32, 0x7, 0x6c, 0x29, 0x45}};
But i need CLSID for SQL CE 3.5
CLSID_SQLSERVERCE_3_5 = ??????
sorry my bad english 
thanks

My guess is, not without also removing the caption.
You could always roll your own message box.

Thanks for the reply.
1)How to remove the caption?
2)Own message box means i have to create new dialog box in resource view and display the message or is there any other method.

Yes, there is probably a way to remove it (I think you have to look at how to remove the system menu or something like that).
But the question I'm asking is why do you want to remove it ? it's part of the normal Windows UI guidelines.

I just want to pop up a message to the user indicating "data is going to load please wait for sometime", It is just a information and data will be loaded even if user press "OK" or cancel button so i wanted to remove it.

It sounds like you want a modeless diaog instead so that the main thread is not blocked.

So, there are no specific requirements to remove the "X" in the caption, so just leave it like that and concentrate on the the real features and/or other technical challenges that you might have.
|
|
|
|
|
Then why can't you use progress bar ??

Click on the X button will give you back the IDCANCEL return value, as if you had pressed ESC or "Cancel" button.

Any message box that can be dismissed with ESC will have a close button. That's just how it works.

Here bmfh is an object of BITMAPFILEHEADER and I am not sure to achieve the core meaning of the statement below can U explain me ?
if(bmfh.bfType != 0x4d42)
{
throw CDibException(CDibException::enm_file_read_filed, "BMPƒtƒ@ƒCƒ‹‚Å‚Í‚ ‚è‚Ü‚¹‚ñ");
}

can't you follow the posting guidelines ?[^] 
for your question, it just tests if the bfType member of your BITMAPFILEHEADER variable is different of the hexadecimal value 0x4d42.
if you can't understand this, maybe you should consider buy a book on C and lear about structs...

Hi,
MSDN[^] says that bfType must be BM.
0x4d - M
0x42 - B

A consistence check for the bitmap file.
Every bitmap file must contain the characters 'B' (0x42) and 'M' (0x4d) at the very beginning.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

I have a sample project and I have to implement this code into my project. I could not understand the theme of the code can you make me understand the code? The code goes like this
void CDib::BmpLoad(CFile& rBmpFile)
{
int nCount, nSize;
BITMAPFILEHEADER bmfh;
nCount = rBmpFile.Read((LPVOID) &bmfh, sizeof(BITMAPFILEHEADER));
if(nCount != sizeof(BITMAPFILEHEADER))
{
throw CDibException(CDibException::enm_file_read_filed, "BMPƒtƒ@ƒCƒ‹ƒTƒCƒY‚ªˆÙí‚Å‚·");
}
// ƒtƒ@ƒCƒ‹ƒwƒbƒ_‚Ì'BM'‚ðŠm”F
if(bmfh.bfType != 0x4d42)
{
throw CDibException(CDibException::enm_file_read_filed, "BMPƒtƒ@ƒCƒ‹‚Å‚Í‚ ‚è‚Ü‚¹‚ñ");
}
nSize = bmfh.bfOffBits - sizeof(BITMAPFILEHEADER);
m_pBmpHead = (LPBITMAPINFOHEADER) new BYTE[nSize];
nCount = rBmpFile.Read(m_pBmpHead, nSize); // info hdr & color table
this->ComputeMetrics();
// BOOL ret;
// m_pImage = (LPBYTE)VirtualAlloc(NULL,m_dwSizeImage,MEM_RESERVE|MEM_COMMIT,PAGE_READWRITE);
// if(m_pImage == NULL)
// VirtualAlloc(&m_pImage,m_dwSizeImage,MEM_COMMIT,PAGE_READWRITE);
// MEMORY_BASIC_INFORMATION MemoryBasicInfo;
// VirtualQuery(m_pImage,&MemoryBasicInfo,sizeof(MemoryBasicInfo));
// if(MemoryBasicInfo.State != MEM_COMMIT)
// return;
// ret =VirtualLock((LPVOID)m_pImage,m_dwSizeImage);
m_pImage = (LPBYTE) new BYTE[m_dwSizeImage];
nCount = rBmpFile.Read(m_pImage, m_dwSizeImage); // image only
// ret =VirtualUnlock((LPVOID)m_pImage,m_dwSizeImage);
this->ComputePaletteSize(m_pBmpHead->biBitCount);
this->MakePalette();
this->MakeDDB();
}

Exactly which statement is troubling you?

Hai,
i am working with IOCP server and normal socket Client. i have created 2 threads in my server side(in a thread pool). and trying to connect more number of clients using threads.
But Only 3969 clients are getting connected at a time....
as of use in IOCP we can connect 65000 clients .....but atleast i want 10,000 clients to connect.
What is the issue over here...
reply me,

How many threads are created in total ?

Do you have one thread that gets created for each clients that connect ?

hai,
thanks for reply, here is my code :
1.for (int ii = 0; ii < nNoOfThreads; ii++)
2.{
3.b = CreateConnectedSocket(&(pThreadInfo[ii].m_Socket),"192.168.60.206", nPortNo);
4.if(b)
5.{
6. pThreadInfo[ii].m_nThreadNo = ii+1;
7. p_hThreads[ii] = CreateThread(NULL, 4096, WorkerThread,(void *)(&pThreadInfo[ii]), STACK_SIZE_PARAM_IS_A_RESERVATION, &nThreadID);
8.}
in for loop "nNoOfThreads= 4500",
and the 3rd line i am creating socket, and trying to connect with passed parameters.
now..each 4500 sockets has o create,
den create thread will take care of message send and receving...
now the issue is only 3969 sockets are created... and the 3969 threads are created.

Do you know what a thread is ? Do you understand that you need some resources to manage one single thread ? Do you also understand that switching between different threads take some time, so imagine what will happen if you have to switch between 10000 threads. Multithreading is achieved by time slicing: your processor will work on one thread for a small amount of time, then switch to another thread for another small amount of time and so on... So, guess what happens when you have 10000 threads ? Nothing works anymore because there are just too much threads to be handled.
D.Mani wrote: What is the issue over here...
You are just asking too much from the system. There not enough memory to manage all the threads that you are creating. This should ring a bell that your design is just plain wrong.
Some people already told you that creating so many thread is a bad idea. Now you see the reason.
