I am having problem with communicating with 3M MT7 EX USB touch screen.
I need to send a calibrate request through C++ code, in order to do that I locate the global device path from SetupDi* functions. The global device path returned is:
\\?\USB#Vid_0596&Pid_0001#5&ee85354&0&2#{a5dcbf10-6530-11d2-901f-00c04fb951ed}
Using this device path I successfully get a handle from CreatFile():
<code> m_hUsbDevice = CreateFile(detailData->DevicePath, GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, (LPSECURITY_ATTRIBUTES)NULL, OPEN_EXISTING, 0, NULL);</code>
When I try writing to this handle I get an error:
ERROR_INVALID_FUNCTION
The code for writing is:
<code>WriteFile(m_hUsbDevice, pucString, 8 , &dwWritten, 0)</code>
pucString is pointer to the below structure
<code>struct stCalibrate
{
Byte RequestType;
Byte Request;
short Value;
short Index;
short Length;
stCalibrate()
{
RequestType = 0x40;
Request = 4;
Value = 0x01;
Index = 0;
Length = 0;
}
};</code>

what does this have to do with C, C++, or MFC?

Since you're comparing outtrainset(i,j) to 0.5, a floating point value, I'd assume just like I told you before that you already have a continuous value as output. As I also said, that if statement is thresholding the output to prodice a crisp boolean answer. If you want the continuous result, just don't do the threshold!
Also, peppering the forum with repeated questions is considered bad form and will generally get you yelled at.You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

Oh, I remember you now. You're the Malaysian gal who was trying to get some fool to send her the code for her senior project a while ago. Guess you must have found one since you can't comprehend what you have.  Maybe I'll report you to your school's acadamic affairs office.You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

I believe 'Add/Remove Program' which has the 'LAST USED ON' column enabled utilizes the NTFS Last Access timestamp[^]

Last two days i'm struggling in CTreeCtrl Image Drag and Drop.
I'm using MFC MDI application having two views
1. Library View
2. Project View
Both the views having Tree Structure. I can able to drag and drop an item from Library view to the Project View but while dragging i need to drag image from one view to the another. I can able to drag image up to the border of the library view(View one) when the pointer enters in to the project view(View two) it disappear and only shows the pointer.
How can i copy the image from my Library view to the Project View.
Any one please help me ...

You could make your own derivation of CTreeCtrl,
with a pointer to CImageList,
that will be set by CreateDragImage(..) at CYourCtrl::OnLButtonDown(..)
and deleted at CYourCtrl::OnLButtonUp(..).
You must set the first parameter of CImageList::DragEnter(..) to NULL
to allow the image to be "global".
All coordinates of the CImageList interface
will be screen-related in this case  modified on Thursday, February 18, 2010 9:17 AM

Hi
I trying to compile a device driver and to avoid compiling in user level functions I’ve specified /NODEFAULTLIB as a makefile flag. The function memset is now reported as a non-resolved function. The memset function is available in LIBCRT.LIB however, whenever I explicitly reference this library in the makefile it generates a number of other non-resolved functions beginning with gs_ which I believe are related to kernel32.lib which is not available to driver .dll’s
Is there an alternative to the memset function I could use?

I guess you may use RtlFillMemory[^].

I ended up inserting the following line in the sources file and it now works:
TARGETLIBS=\WinDDK\7600.16385.0\lib\wnet\i386\libcntpr.lib
As it works I'm assuming that this is a kernel equivalent to libcnt.lib?

Hi All,
I am trying to install the .inf file through cmd line
rundll32 syssetup,SetupInfObjectInstallAction DefaultInstall 128 .\mfile.inf
It runs fine with wondows xp and windows 7 but in windows vista I am getting error message "Installation failed".
Even UAC also disabled. What might be the problem?

I have only inf file and want to install.
What information you want?

If I could do that then no need of your help

| As I said in answer to your earlier post, the message "Installation failed" gives no clue as to what might be wrong, so there is no way we could begin to guess what the error is.
