Hi! Sir,
You know that we can disable USB Enhanced Host Controller by hand.That is,
right click my computer,select property,select hardware,click Device Manager,
click General Serial Bus Controller,right click USB Enhanced Host Controller,
select Disable,so,we disabled this device.
Now my question is: how to disable USB Enhanced Host Controller by VC code?
Couse i wanna my usb device run under usb1.1 but not usb2.0,so i have to disable
USB Enhanced Host Controller in my vc code before attach my usb device to pc.
Thanks for any help!
All the blesses we enjoy are the fruits of labor,toil,study and self-denail.

Hi!
While executing a code ported from VC6 to VC8, I an getting unhandled exception. When I debugged my code I found that LoadFrame() is causing a probelm saying::
First-chance exception at 0x104817fd (msvcp80d.dll) in KPVault.exe: 0xC0000005: Access violation writing location 0x0000424b.<br />
Unhandled exception at 0x104817fd (msvcp80d.dll) in KPVault.exe: 0xC0000005: Access violation writing location 0x0000424b.
I am calling LoadFrame as
CMainFrame* pFrame = new CMainFrame;<br />
pFrame->LoadFrame(IDR_MAINFRAME,<br />
WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE, NULL,<br />
NULL);
I checked all my resources named as IDR_MAINFRAME. Those are a String, Menu, Acceralator, Icon and a Toolbar.
VC6 build for the same code runs just fine. Then What is causing this problem??
Thx.

Hi,

Is there anything I need to do in terams of finding the corresponding definition on x64. In case I do need to where I can get the definition.
<classname>.obj : error LNK2019: unresolved external symbol HtmlHelpA referenced in function "public: int __cdecl <classname>::LinkToHTMLHelp(unsigned long)" (?LinkToHTMLHelp@CTapas@@QEAAHK@Z)

You get this because the function is not defined for 64bit, probably the prototype is surrounded by #ifdef WINxx or something like that. Find where the 64b version is located, and include it.

The prototype of the function is defined as below in the file htmlhelp.h under winxpsdk/include (SDK code) path.
HWND WINAPI HtmlHelp(
HWND hwndCaller,
LPCSTR pszFile,
UINT uCommand,
DWORD_PTR dwData
);
I dont have the cpp file with me and have no idea which extra lib if any is to be included for the x64 platform to execute the build.
Thanks

the FillList4 is loaded in my oninit dialog !
void CMyList::FillList4()
{
CNote *pNote = new CNote();
pNote->Open();
CString sNrInregistrare;
if (pNote->GetRecordCount())
pNote->MoveFirst();
int x = 0;
while(!pNote->IsEOF())
{
int nItem = m_list4.InsertItem(x, pNote->m_name);
m_list4.SetItemText(nItem, 1, pNote->m_city);
pNote->MoveNext();

It looks really weird. What is the hardware configuration of the machine where it took 10 minutes to load this 1000 or 1500 records?
Comment out the data access code and insert the same number of hard coded strings in a loop into the ListCtrls. Check what the time for this is. If it takes less time, then we can confirm that the issue is with db access, may be indexing is missing.
Try this and see what the result is.

It looks ur hardware is more than enough and it should not take that much time. So issue is in ur CNote. its better u change that code with ADO or try whatever google link kakan mentioned.

The problem might be in your class CNote. What does it look like?

CNote is CRecordset class default generated by microsoft visual c++

I Googled around for "CRecordset slow" and found this at http://forums.mysql.com/read.php?45,99701,99721#msg-99721[^]
The text:
Resolved:
Apparently, for whatever reason, Microsoft's CRecordset C/C++ class is literally copying the entire table over to the local client with the CRecordset::Open function.
This is probably why the original coders were using a dynaset when we were using MSACCESS, but when I switched over to MYSQL, dynaset's were not supported with the MySQL/ODBC drivers so I used snapshots instead.
I changed the logic to use a direct SQL command and its lightning fast now.
Try my Google search (and variations). I guess you will find the reason (and the solution) of your problems.

Don't ask me how to run a direct SQL query from your program, Iv'e never done it. But there is heaps of samples out there.

What is so hard about changing from dynaset to snapshot?

How many items are being loaded? If it's more than just a few thousand, you'll need to use a "virtual" list control.
What does CNote::GetSQL() look like?

If my code was not any better than what you had, then why are you using it?
