Re: Sizing my dialog - C / C++ / MFC Discussion Boards

Hi Mark,

First thanks for your help, truly appreciated.

Here's the bottom line I have tried practically all permutations
of mapping modes ... with latest one as shown. Here is the one consistancy, despite the fact that, pDC->GetDeviceCaps (PHYSICALOFFSETX);
pDC->GetDeviceCaps (PHYSICALOFFSETY); are the same (happens to be 100 for both) location 0,0 offset's horizontally 1/8 of inch and vertically 1/4
of an inch. The same happens for any point. Any clues as to why I keep getting this discranpency ?

r_xmargin = pDC->GetDeviceCaps (PHYSICALOFFSETX);
r_ymargin = pDC->GetDeviceCaps (PHYSICALOFFSETY);

pDC->SetMapMode(MM_ISOTROPIC);
pDC->SetWindowOrg(0, 0);
pDC->SetWindowExt(600, 600); // logical window is 600 dpi
pDC->SetViewportOrg(0, 0);

// GetDeviceCaps(LOGPIXELSX)and Y are 600
// Device viewport is dpi of actual output device.
pDC->SetViewportExt(pDC->GetDeviceCaps(LOGPIXELSX),
pDC->GetDeviceCaps(LOGPIXELSY));

// r_xmargin and r_ymargin happen to both be 100
pDC->SetTextAlign (TA_LEFT | TA_TOP);
pDC->TextOut (0, 0, "x", 1);
pDC->TextOut (r_xmargin, 100, "x", 1);
pDC->TextOut (r_xmargin/2, 200, "x", 1);
pDC-?TextOut (r_xmargin + 50, 300, "x", 1);

Thanks again

Do GetDeviceCaps(LOGPIXELSX) and GetDeviceCaps(LOGPIXELSY) give you the same values?

Also, instead of printing text to test this, draw lines or solid blocks.
Your "x" text is immediately going to add some "margin" above the "x"
since it's not a capital letter. Of course, there's more font metrics involved
than just the height. Drawing graphics will give you a much better idea what
you're working with.

What type of printer is it?

Here's a quick sample to plop into a new CScrollView doc/view app to see if the results are consistent using print preview. It's more of a WYSIWYG approach and simplifies printing because it uses the same drawing code to print that is used for the screen. Try this out in a new project then adapt what you need to your application.

NOTE: This was previous post of mine describing the print paging mechanism to someone but it demonstrates general printing. I hope it helps.

Hello All
I am using a dialog as my main window, and I set it to center to screen I had put that code in the
this->CenterWindow(CWnd::GetDesktopWindow());
//code here to set dialog size.
on the OnInitDialog
and i dont know how to set width and height of the dialog without using "SetWindowPos"

and i have another issue i want to resize my window and keep it in the center of screen all of that in runtime, due some user clicks.

any help?

Why do you dislike SetWindowPos?

Can't you handle WM_MOVE message?

U can Use this OnInit....

<br />
CRect Rect;<br />
    GetParentFrame()->GetWindowRect(&Rect);<br />
    GetParentFrame()->SetWindowPos( NULL,0,0,900 ,200 ,SWP_NOMOVE | SWP_NOZORDER);  <br />
    SIZE size;<br />
    size.cx=Rect.Width();<br />
    size.cy=Rect.Height()/2;<br />
    SetScaleToFitSize(size);<br />

How about MoveWindow()?

You can use of MoveWindow on the WM_SIZE event.

Hello! I transferred a function from a client program into a windows service. At the client Programm I used PlaySound(WavFile, NULL, SND_FILENAME | SND_ASYNC | SND_LOOP); to play a wav file.
At the service there's no output at all. Anyone knows a solution like Setting Default Audio Device via program or another function that could make it work?
Or is there no possibility to do such things?

I would be doubtful about the ability existing. Can you imagine the consequences if it did?

You'd have all sorts of services deciding that they are the One True Service, making a hullaballoo, and no UI to shut them up. Volume settings are on a per user basis too, I think. So, which user profile do you use?

If noone's logged on, who's going to pay ettention anyway?

I suggest you have a really tiddle client program for the service to communicate with, and let *that* program make the noise - or a balloon tooltip, etc. Then "I" can kill it.

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong. You wouldn't be the first...

That's probably a good thing.

You're right in saying that it's not so bad that it is this way, but how I would use the service it makes sense in my opinion.
I found a solution to solve my problem, but it's not as good as if I could do the action needed in the service.
The difficulty is that one or more programs consume the service but only one user must play the sound ( a telephone ring).
So I tell one instance via application logic to do it. Quick and dirty Smile | :)

Ty for your helpful comments.

i need to get a file from windows XP machine to my XP desktop, in both machines IIS services running. I have no error in InternetConnect(), InternetOpen(). But FtpOpenFile() fails and returns "file unavailable error". Following is the code i did in FtpOpenFile,
FtpOpenFile(hConnect, TEXT("C:/good.txt"), GENERIC_READ, FTP_TRANSFER_TYPE_BINARY, NULL);

Anybody have any idea to overcome this. Somebody respond ASAP please.

Does the file exist? Have you tried a (double) backslash instead?

So now you have something akin to:

if (FtpOpenFile(hConnect, TEXT("C:\\good.txt"), GENERIC_READ, FTP_TRANSFER_TYPE_BINARY, NULL) == NULL)
    DWORD dwError = GetLastError();

"Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for, in order to get to the job you need to pay for the clothes and the car and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman

"To have a respect for ourselves guides our morals; to have deference for others governs our manners." - Laurence Sterne

this is also didn't work out. Confused | :confused:

What does GetLastError() return?

"Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for, in order to get to the job you need to pay for the clothes and the car and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman

"To have a respect for ourselves guides our morals; to have deference for others governs our manners." - Laurence Sterne

it returns 12003.

Which equates to ERROR_INTERNET_EXTENDED_ERROR. Did you then call InternetGetLastResponseInfo() to get the error text?

Tried as InternetGetLastResponseInfo(lpdwError, lpszBuffer, lpdwBufferLength);
cout<<lpszBuffer;

if this is correct, it have 00394BD8.

it is didn't work. if i use InternetGetLastResponseInfo() & ran the program means, it breaks the code.

But FtpOpenFile() returns the error code as 6 now. where can i refer the error codes?
