i m using table in database, here diffrent type of data types i m using.
when i m add entries in table in form of special characters than this error comes.
i m not using very long data like for Text data type i m using less than 255 characters.
please help me for this.

Can you show your database schema? What code are you using to update the database? What is the exact error message?

hi,
I want to run an internet explorer on my application, which is C++ and on Microsoft Visual Studio (on PocketPc or Windows Mobile Platform).
I use a class CWebBrowser to work with this Control.
I use RegEdit for Mobile and I can't find the GUID of that control on my mobile, therefore the control does not create.
(GUID = 8856F961-340A-11D0-A96B-00C04FD705A2 )
(CLSID = { 0x8856f961, 0x340a, 0x11d0, { 0xa9, 0x6b, 0x0, 0xc0, 0x4f, 0xd7, 0x5, 0xa2 } } )
would someone help me to solve my problem.
Thanks

The REFIID of Pocket Internet Explorer is: L"Microsoft.PIEDocView".

Thanks for your answer,
I found that CLSID of the "Microsoft.PIEDocView" which was {F5AFC7EF-1571-48B6-A69C-F1833F4C3A44} , I changed the CLSID of CWebBrowser to that, and the Message blew was writen:
...
Load module: browsres.96.dll
Persistence not supported on OLE control {F5AFC7EF-1571-48B6-A69C-F1833F4C3A44}.
>>> Result code: 0x00000000
Load module: WEBVIEW.DLL
...
and the control did not create.
Do you know waht can I do with that?

Hi,
Maybe you didn't call ::CoInitializeEx() or otherwise initialize properly.
For diagnostic, compile the ATL sample in <Windows Mobile [5 | 6]\Samples\PocketPC\CPP\ATL\Minipie> and/or the WTL adaptation in <WTL8>\Samples\MiniPie and run the result on your device.
On success, your development environment is OK and there is a problem in your code, otherwise the problem is on your development platform.
cheers,
AR

Hi,
Thanks a lot for your help,
i run the sample and it works properly, i think i must change my codes.

In a header file I have
#define NOMINDEX 0
...
#define ETABLESIZE 5
In the source file that includes this header, the following doesn't seem to work (it's writing 0 to the buffer (and in the watch window in VS, it's saying it doesn't recognise the symbols defined)
sprintf_s( eBuff, 16, "%d", energyTable[ETABLESIZE*sel + NOMINDEX] );
if I add this line before it, "e" is correctly assigned to 5
int e = ETABLESIZE;
sprintf_s( eBuff, 16, "%d", energyTable[ETABLESIZE*sel + NOMINDEX] );
In other parts of my cpp file I use these constants and they seem to work correctly.
Have I done something incredibly stupid?
cheers

The answer of course is, yes, I was doing something incredibly stupid. I really ought to try the count to 10 rule before posting 
unsurprisingly,
sprintf_s( eBuff, 16, "%.0f", energyTable[ETABLESIZE*sel + NOMINDEX] );
works rather better, since energyTable is a float array
DOH!
sorry.....

Could it be that your sel variable is 0 and you just didn't notice?

It should work, indeed. That stated, why don't you use an enum for your symbols?

I want to get the info about all (currently 4) cpu-cores I have.
The most information I get is with the WMI-system (WIN32_processor).
I found at all web-pages the same sample-code for the WMI-access with C++.
I changed it for my needs and it works almost fine. The only
problem is that it gives me only the data for CPU0, but not
the 3 others.
As soon as i change the WQL request to ("SELECT * FROM Win32_Process")
the "while (pEnumerator)"-loop works fine and I get all processes currently running.
So I don't understand why the WQL request returns only the first CPU...
Thanks a lot for any help!
best regards

How many processors do you actually have? I think you'd have to agree that there's only 1. That is why WMI only returns one Win32_Processor record. However, Win32_Processor has a NumberOfCores property that should return '4' for you - it returns '2' for me (I only have an E6600, so only two cores).
|
|
|
|

1) The last lines of my entry show the output of my application. Fact: I have 4 cores.
2) I use VisualStudio 2005 and there I cannot find any "NumberOfCores" at WIN32_processor...??
3) I need the LoadPercentage of each core and not only one of them...

Ok. I found it, but that's value I already get with GetSystemInfo(). I still need to get the MWI-objects for all four CPU-cores...
|
|
|
|
|
It seems to be a problem at the window-side. I could test my software on a single-core CPU with Hyperthreading (number of cores = 2) and in this case I got the data for both "cores"...

Hi friends,
I had tried to stretch a Gif image and unable to do
My code is :
CImage image;
HDC dc = GetWindowDC()->GetSafeHdc();
BYTE *m_buffer;
CFile file;
if( !file.Open( MAKEINTRESOURCE(IDR_GIF1), CFile::modeRead) )
return false;
long m_buffer_size = (long)file.GetLength();
m_buffer = new BYTE[m_buffer_size];
if ( file.Read(m_buffer, m_buffer_size) != m_buffer_size )
return false;
file.Close();
IStream *pIstream;
CreateStreamOnHGlobal(NULL, TRUE, (LPSTREAM*)&pIstream);
ULARGE_INTEGER ulnSize;
ulnSize.QuadPart = m_buffer_size;
pIstream->SetSize(ulnSize);
LARGE_INTEGER lnOffset;
lnOffset.QuadPart = 0; //starting location is 0
pIstream->Seek(lnOffset, STREAM_SEEK_SET, NULL);
ULONG mysize;
pIstream->Write(m_buffer,m_buffer_size,&mysize);
image.Load(pIstream);
CRect rectDest;
rectDest.top = 0;
rectDest.bottom = 50;
rectDest.left = 0;
rectDest.right = 50;
image.StretchBlt(dc, rectDest, PATCOPY);
image.Draw(dc,0,0);
Kindly help me ..
Thanks in Advance..

Try SRCCOPY rather than PATCOPY?
|
|
|
|

Thanks for your kind reply,
I had tried it and doesn't work
i hope the coding itself getting wrong
if you have any other method
kindly send me
Thanks & Regards,
Jeeva

OK, here's the answer I was going to give you before I realised that PATCOPY doesn't work and SRCCOPY does (by trying it).
You have a whole load of steps - any one of which could be failing. You don't check returned status codes - any one of them could be failing and you don't know. So, try adding some error checking so you know what's going wrong.
Also, what's with the IStream and HGlobal stuff? You don't need that to read a CImage from a file - here's the code I'm using in my OnPaint:
PAINTSTRUCT ps;
CDC * drawDC = BeginPaint(&ps);
CRect rcClient;
GetClientRect(&rcClient);
CImage image;
image.Load(_T(image filename));
image.StretchBlt(*drawDC, rcClient, SRCCOPY);
EndPaint(&ps);
Simpler, no? Simple's good.
