Hi
Im trying to draw a rectangle with rounded corners, using GDI and Win32, I can't use MFC.
But, in the parts that nothing should be drawed I still can see the image, but in pink :S
Any sugestions?

The code I'm using is

// Draw the mask
bmp = LoadBitmap(hInst,MAKEINTRESOURCE(IDB_MASKPRUEBA));
hbmold = (HBITMAP) SelectObject(memdc, bmp);
BitBlt(hdc, 0, 0, 536, 300, memdc, 0, 0, SRCAND);
DeleteObject(bmp);

//Draw the picture
hbmold = (HBITMAP) SelectObject(memdc, bmp);
BitBlt(hdc, 0, 0, 536, 300, memdc, 0, 0, SRCPAINT);

Thanks in advance

link with msimg32.lib

or, you might take a look at article Q79212 in the MSDN, if you just need to make a single color transparent.

LogonUser (Sort of)

Eurosid23-Sep-05 8:05

I have a desktop application that must authenticate each user.

I am not allowed to have my own password file, nor to store
passwords in a database.

The application needs to work on XP and Win2K, and
will be written in VC6++.

LogonUser looks perfect, because it lets me authenticate
the passwords the same way that Windows does when users
log in every day.

It works fine on XP. It fails on Win2K, of course, because
SE_TCB_NAME is not granted to user accounts.

Any suggestions for something similar? I do NOT
need the token that is normally generated by
LogonUser, as I'm not starting a service or
impersonating a user. I only need the BOOL that
tells me the password is valid or not.

mmmm... I wouldn`t like to log on on an application using my windows password... I never know what are you going to do with it.

I think you need to look for another approach.
If you need login in an application you will need an encripted passwords file.

Company IT policy doesn't allow me to keep
my own password file, even if it is encrypted.

We thought of using the Windows password because
it is an authenticaion system already available
in the company.

if the user is logged in and is using your program then they are already authenticated. If you are doing this over a network then you could use named pipes and check the user at the other end..

I also argued the position that logging into Windows should suffice.

After all, Office works this way. We use Outlook here, and you
need not provide a seperate password for that.

The local powers here were unconvinced, so I have been looking
for a way to do it.

Thanks.

Choose printer automatically

There is a way to do this.
Here is a CP article in Purgatory:

The CP article points to a Microsoft KB article:

Yes. You can try CPrintDialog.

Yes. You'll also want to check out the CDC class as it has most of these as member functions.

Search MSDN for SetPrinterDevice - there is function you can write in CApp to change app current printer by name. Then default MFC printing routine will use it. Contact me in private, if you will not find it - I will send it to you.

Create a handler for the WM_LBUTTONDOWN message and then call MessageBox(). Is that at all what you were looking for?

I've got problems to get the handler with the edit box. My code is:

void CSubtitlesDlg::OnLButtonDown(UINT nFlags, CPoint point)
{

CEdit* pW = NULL;
pW= (CEdit*) GetDlgItem(IDC_EDIT_SUBTITLES_LIST);
GotoDlgCtrl(pW);
AfxMessageBox("Click sobre la lista de subtítulos");

SetFocus();
}
