OK, when you create your app, you can choose printing support from the wizard, this gives you the framework you need to do printing, and there's heaps of info online about using it.

Stringer's printing class library to print some other image format like a tiff. If I could modify that code to print a tiff (and a
bitmap) that could overlay text, then it might print faster and
Id be happy.
Some printers will let you send a tiff, but I don't know how many. If you want to draw on the bitmap, then it needs to be a bmp in memory. I really don't know how to stream a tiff to a printer, although obviously the first step would be reading it as a byte stream.

Anybody knows how to get SPDRP_FRIENDLYNAME in SetupDiGetDeviceRegistryProperty from USB disk, the buffer I get always invalid?In addition Can It works under Win98?
DEFINE_GUID(GUID_CLASS_USB_DEVICE,
0xA5DCBF10, 0x6530, 0x11D2, 0x90, 0x1F, 0x00, 0xC0, 0x4F, 0xB9, 0x51, 0xED);
hDevInfo = SetupDiGetClassDevs((LPGUID)&GUID_CLASS_USB_DEVICE,
0, 0, DIGCF_PRESENT | DIGCF_DEVICEINTERFACE);
if (hDevInfo == INVALID_HANDLE_VALUE)
return false;
DeviceInfoData.cbSize = sizeof(SP_DEVINFO_DATA);
for (i = 0 ; SetupDiEnumDeviceInfo(hDevInfo, i, &DeviceInfoData) ; i++)
{
DWORD DataT;
LPTSTR buffer = new char[1024];
DWORD buffersize = 1024;
SetupDiEnumDeviceInterfaces (hDevInfo, 0, &DeviceInfoData.ClassGuid, i, &DInfoData);
while (!SetupDiGetDeviceRegistryProperty(hDevInfo, &DeviceInfoData,
SPDRP_FRIENDLYNAME, &DataT, (PBYTE)buffer, buffersize, &buffersize))
...

Hello,
I'm writing an application that uses MFC.
It is a kind of media player and I use CListCtrl to display playlist.
But I get a strange error when I add items to my list control. After the 17th item added, my app crashs with a message box showing "Invalid Hook Descriptor".
I am attaching some code. To keep it simple, I've just extracted parts liable to contain the bad code : the overrided Create member method and the UpdateList method.
An explanation : I'm displaying playlist. So I read the M3U file and I call Update list method to add the file paths to the CListCtrl.
Any help would be appreciated. That bug is driving me crazy.
Thanks

hi,
beginner question: how would I implement a "number picker" control where there is an up/down button (like from a vertical scrollbar) and as you click up the number increments by one, down decrements by one until it hits zero, then when I hit ok it gives me the number I chose. Thanks!
|

Look up Up-Down Controls in MSDN. (The CSpinButtonCtrl class if you're using MFC.)

Thanks, that worked! One question, the up arrow makes the numbers decrease, and the down arrow makes them increase. Any way to reverse that? Thanks again!
|
|
|
|

That's the default behavior. You have to manualy set the range, direction and all that. You can even set an acceleration--how it goes slow at first then speeds up. You can also set whether to insert a thousands separator if appropriate.

i have a struct array:
typedef struct _PERSON
{
TCHAR *firstName;
TCHAR *lastName;
TCHAR *address;
TCHAR *phone;
} PERSON;
which a properly alloc in annn array of people[10]
then i call:
myAddressBook *book = new myAddressBook(_T("first"),_T("slast"),_T("phone"),_T("add"));
book->addPerson(_T("first"),_T("aaaaa"),_T("phone"),_T("add"));
book->addPerson(_T("first"),_T("bbbbb"),_T("phone"),_T("add"));
book->addPerson(_T("first"),_T("ddddd"),_T("phone"),_T("add"));
book->addPerson(_T("first"),_T("ccccc"),_T("phone"),_T("add"));
book->sortPeople(book->people,book->mTotal);
heres the func:
void myAddressBook::sortPeople(PERSON *per, int num)
{
PERSON *temp;
for (int x=0;x<(mTotal-1); x++)
{
if (_tcsncmp(per[x].lastName, per[x+1].lastName, _tcslen(per[x].lastName)) > 0)
{
//str2 is biggerr, so- swap em
temp = &per[x];
per[x] = per[x+1];
per[x+1] = *temp;
}
}
}
the results are not right, duplicated entries and other oddness, whats wrong?

kerrywes wrote: per[x+1] = *temp;
that doesn't seem right.
shouldn't it be "per[x+1]=temp;"
i assume per is an array of pointers to PERSONs

The fault is with the the copy routines.
temp = &per[x] gets just a pointer but then per[x] = per[x+1] does a copy, destroying the original data. You need to force copies for each of the swap operations. You also need to make temp a value, not a pointer.
temp = per[x];
per[x] = per[x+1];
per[x+1] = temp;
Ultimately, this realy doesn't do a sort, though. It just does a single pass through the array. Look up bubble sort to learn how to do a very basic sort.
(Generally, using qsort, or some version thereof, would be better.)

Hi
In 3 you save the address of per[x] but replace the content of that !
must change to
{<br />
*temp = per[x];<br />
per[x] = per[x+1];<br />
per[x+1] = *temp;<br />
}
but in this case you have a problem that the temp is pointer, you most declere it as
PERSON temp;

hi everybody , ive used the code published here( named w3client) to connect to hotmail and tried to login to ,but it dosent work. can anyone help please ?
url="https://login.passport.com";
_pclient->Request("/ppsecure/post.srf", W3Client::reqPost);

Hi
I got an app - all works fine including tooltips for ctrls.
Now i want to add Tooltips for my owner drawn objects.
I got the
void MyAppView::OnDraw(CDC* pDC)
{
// Raute
pDC->MoveTo(20,30);
pDC->LineTo(24,25);
pDC->LineTo(20,20);
pDC->LineTo(24,35);
pDC->LineTo(20,30);
}
Now i want to Tooltip "Raute" the cursor is inside this area
But nothing happens?
Using "myAppView::OnToolHitTest(...){...}" does not display anything.
THX

}
}
The problem is sometimes all the strings on "OnMail" functions goes to the server and i can see the answers on my received windows.
For example when IDC_SIMULTANEOS = 1(1 thread) its works fine.
When threads are bigger than 1 the results on my received window are disordered, here is an example of 2 simultaneous threads sending 3 mails each.

The flow was stopped and only 3 mails were send.
My question is why this works well sometimes and sometimes dont if i am inserting the sames values?
I think i can solve it with an event but i dont know where to set and unset.
I search documentation but i never see how to works with threads created like this.
Thanx in advance.

When does OnMail get called? If it can get called from multiple threads, then that explains the jumbled order. Also, each thread will read whatever is available in the UI at *that* point of time, maybe that explains the "invalid command" errors?

thanx for the answer.
onconnect gets called when the users press the "connect botton" and onmail is called when the user press the "sendmail" button.
the invalid commands are becouse in a previous version of the program i put an "\r\n" justo before the "ehlo" and the server take that as invalid.
i think i copy the second receive window that version of the programa but the problem is the same in the new one without the unrecognized commands.
thanx again and i hope help.
