Yes i tried that but have same issue there.

OK.
(May be other windows do not know how to draw it...)
Would you set another application cursor instead ?  Check your definition of Irrationality[ ^]

m_pDestTreeCtrl->m_pDragImage = m_pSourceTreeCtrl->m_pDragImage;
is it ok??
If you find any useful link pls give it to give me..

Hi,
My application exe is not working on another machine (XP), when I try to launch It displays error like:
CreateProcess failed;code 14001
The application failed to start because the application configuration file is incorrect. Reinstalling the application may fix the problem.
What configuration has to set?

| Did u gaive the MFC option as "Use MFC in a Static Library" and build your application. Just check ( [^]) Величие не Бога может быть недооценена.

|
|
its a win32 application (windows)
|
|

| Just build the application with the configuration mentioned above. Величие не Бога может быть недооценена.

Just reinstall the vc software.

Do you really think it would be the solution: installing,for instance, Visual C++ on every customer machine?  If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

How can I add word wrap to this code for drawing text:
CPaintDC dc(this);
CRect r;
GetClientRect(&r);
Gdiplus::Graphics* g = Gdiplus::Graphics::FromHDC(dc.m_hDC);
CString txt;
GetWindowText(txt);
Gdiplus::Font myFont(m_FontName, m_FontSize, m_FontStyle);
Gdiplus::StringFormat format;
Gdiplus::RectF rf;
g->MeasureString(txt, txt.GetLength(), &myFont, Gdiplus::PointF(r.left, r.top), &rf);
Gdiplus::Color color;
color.SetFromCOLORREF(m_Color);
Gdiplus::SolidBrush whiteBrush(color);
g->DrawString(txt, txt.GetLength(), &myFont,
rf, &format, &whiteBrush);
g->Flush();
delete g; There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

Graphics.DrawString takes a bounding rectangle, give it the maximum width you want, and sufficient height.
Graphics.MeasureString will calculate the required height when given the (same) maximum width.

Hey ,
i study technical computer science and now i want to start with my first driver under WINXP and WINDDK.
I have written two programs to display all connected devices to the computer and a real life detection of adding and removing to the system on two different ways.
/***************/
first:
i build a console application like "usb view" from microsoft to list all devices connected to the pc. After detecting the descriptor i want to start with reading and writing.
To get the usb device i used the IOCTL commands from <a href="http://msdn.microsoft.com/en-us/library/aa476229.aspx">http://msdn.microsoft.com/en-us/library/aa476229.aspx</a>[<a href="http://msdn.microsoft.com/en-us/library/aa476229.aspx" target="_blank" title="New Window">^</a>]
1.) detect host controller (worked)
2.) connect to root hub (worked)
3.) list all ports and connected devices (worked)
4.) fill structe with device desciptor and more
usefull data with this code
IOCTL_USB_GET_NODE_CONNECTION_INFORMATION (worked)
5.) create handle to usb device (problems)
i dont know on which way i can detect the full device path like
\\\\?\\USB#Vid_####&Pid_#####879fe23a000000e83230303630313130#{a5dcbf10-6530-11d2-901f-00c04fb951ed}
or detect a direct handle, i have only the handle to the root hub and the port number.
this is my structure
------------------------------------------
<code>
typedef struct _USB_DEVICES {
HANDLE hDeviceHandle; //RotHubHandle
HANDLE hUSBDeviceHandle; //USBDeviceHandle -> ???
DWORD dwPort; //Port
UCHAR CurrentConfigurationValue;
UCHAR DeviceAddress[2];
UCHAR NumberOfOpenPipes[4];
UCHAR ConnectionStatus[4];
BOOLEAN LowSpeed;
BOOLEAN DeviceIsHub;
USB_PIPE_INFO PipeList[32];
USB_DEVICE_DESCRIPTOR DeviceDescriptor;
USB_CONNECTION_STATUS DeviceStatus;
USB_CONFIGURATION_DESCRIPTOR ConfigurationDescriptor;
USB_INTERFACE_DESCRIPTOR InterfaceDescriptor;
} Ts_UsbDevices;
</code>
------------------------------------------
and now my code
------------------------------------------
<code>
......
//get information aber the connected device connected on "dwPort"
ConnectionInformation.ConnectionIndex = s_UsbDevice[dwActiveDevice].dwPort;
bSuccess = DeviceIoControl(s_UsbDevice[dwActiveDevice].hDeviceHandle, -> RootHubHandle
IOCTL_USB_GET_NODE_CONNECTION_INFORMATION,
&ConnectionInformation,
sizeof(ConnectionInformation),
&ConnectionInformation,
sizeof(ConnectionInformation),
&dwBytesReturned,
NULL);
if(bSuccess)
{
// get DeviceName or Handle to start with reading and writing
...
}
</code>
------------------------------------------
i dont know which IOCTL i have to use or on which way i can try to implement some read and wirte functions...
after this problems i checked the internet and found the SetupDi functions and that was the reasen why i started to write a seccond programm
/***************/
seccond:
like the first programm, i build a console application which list all devices. With this function i can detect the device path to create a handle
1.) get all connected devices with SetupDiGetClassDevs() (worked)
2.) get inferfaces with SetupDiEnumDeviceInterfaces() (worked)
3.) get interface details with SetupDiGetInterfaceDeviceDetail() (worked)
4.) CreateFile / DeviceIoControl failed (problems)
i have 3 devices connected to my computer via usb (keyboard, mouse, mtp device (iriver clix), when i tried to create a hanlde to the mouse and keyboard i get this message:
ERROR_GEN_FAILURE 31 (0x1F) - A device attached to the system is not functioning.
ok.. i found out, that microsoft has blocked this devices.. no problem... i dont want to use this.
Then i create a handle to the mtp device and their i have at first no problem. (no error code)
then i tried to test a lot a IOCTL codes with DeviceIoControl to get somme information or to read but erverytime i get the same error message (ERROR_GEN_FAILURE)
i looked in the internet and a lot of people do it on the same way and have no problem. i dont know whats going wrong.

Hai,
I am having a C++ exe. I want to connect the exe to a databse that is present in another computer(server) and get images from that system.How I can accomplish this?
Thanks,

Hi all
I am trying to fetch data from ORACLE.Connection part is working.When i try to fetch the data then i am getting error.

I am trying give some details.
Table

Through this way i am trying to fetch the data.

try

}
catch(_com_error pCE)
{
CString error;
error.Format(_T("\n%s Error: %ld\r\n%s\r\n%s\r\n"),(TCHAR*)pCE.Source(),pCE.Error(),(TCHAR*)pCE.Description(),(TCHAR*)pCE.ErrorMessage());
AfxMessageBox(error);
}
Please help me where i am wrong.

I would look at

- Im not sure that has a mapping from Oracle to OLE DB - not sure what you do to get around it -
everything else you specify has raw, number, varchar2 etc which seem ok.
Do a test - remove the

and see if it chucks a farley then - if it works, thats the issue !

yes you are right.I had check remove the "SUBSCRIBERS" column then it's working fine.But Can you tell me some different way to do that because we can't remove column.I think it's "SUBSCRIBERS" a use define data type.
If you have different idea then plz help me

|

pretty sure you cant do anything with Oracle AQ through the OLE DB Layer - you might have to use OCI - you might want to check the Oracle dev site for what the .NET client offers as well
