 Thanks David, I knew I should have checked.
The quote came from one of my new class mates who insured me that it was accurate and that I did not need to verify the source, since he wrote a paper on the author.

Hi, I have a quick question on the printing:
I have a VC++ 6.0 application that prints labels on the label paper. In my printer (Canon i550), it prints properly within the dimension of the label. The way I print from the application is that I use GetPrinterDC() and attach it to CDC and then do TextOut to print at certain location.
It prints correctly on my printer however when I tried to print on a different printer (Epson), the font became slightly bigger and the contents go out of the specified label area.
What do I do to fix this issue?
Here is the code that print:
CDC dc;
dc.Attach(printdlog.GetPrinterDC());
DOCINFO docinfo;
memset(&docinfo,0,sizeof(docinfo));
docinfo.cbSize = sizeof(DOCINFO);
docinfo.lpszDocName = "Labels"; // document name for the spooler
CFont f;
f.CreateFont(54,0,0,0,100,0,0,0,0,0,0,ANTIALIASED_QUALITY,0,"Arial");
dc.SelectObject(f);
if (dc.StartDoc(&docinfo) > 0)
{
dc.StartPage();
dc.SetMapMode(MM_TEXT);
dc.TextOut(i_Width-120, i_Height, m_Tit);
.
.
.
Thanks for your help,
JK

You can use GetTextExtent to see how 'wide' your text will be. If it is too wide for the label, then recreate the font with a smaller height so that it will fit on the label.
You are merely being subjected to the different interpretations of the fonts within the different printers.

Hi,
i want to extract a zip file for which i used ShellExecute()
from my VC++ program. since it is a password protected zip file i had to pass that password too to that function.but when i do that i got the error as
Winzip parameter validation error.
the code i used is
ShellExecute(NULL, "open", "winzip.exe", "-e -s"+bcs+" E:\\bcs.zip","C:\\extract\\here", SW_SHOWNORMAL);
where bcs is my password.
im not sure whether ShellExecute() is the appropriate fn for this.if anyone can suggest another method, please help me

you build a command line as described in the page i've sent you, and pass it to shell execute...

hi
thank you for the sudden reply
i am new to VC++.can you give me a mall example to build a command line.
thanks in advance.

it has nothing to do with vc++....
look at what you wrote :
ShellExecute(NULL, "open", "winzip.exe", "-e -s"+bcs+" E:\\bcs.zip","C:\\extract\\here", SW_SHOWNORMAL);
You already gave a command line ("-e -s"+bcs+" E:\\bcs.zip") just add the proper password command line ....

Open a command line box and do it manually then use that for your ShellExecute values.
It might be worth copying the command line to a window so you know that you have generated the correct comand line.

Shouldn't -e be one of -ex, -en, -ef, -es, or -e0?
Is bcs the actual password, or is it a variable containing the password?

Although this settings doesn't crash my tested application....
Maybe you should concider this:
Owner draw
Controls the owner-draw characteristics of the list box. Possible values are as follows:
· No (default): Turns off the owner-draw style. The list box contains strings.
· Fixed: Specifies that the owner of the list box is responsible for drawing its contents and that the items in the list box are the same height.
CWnd::OnMeasureItem is called when the list box is created and CWnd::OnDrawItem is called when a visual aspect of the list box has changed.
· Variable: Specifies that the owner of the list box is responsible for drawing its contents and that the items in the list box are variable in height.
CWnd::OnMeasureItem is called for each item in the list when the list box is created and CWnd::OnDrawItem is called when a visual aspect of the list box has changed.

Hi ,
Iam using the following code to load an icon
HICON hIconImage;<br />
hIconImage = (HICON)LoadImage(NULL, MAKEINTRESOURCE (IDR_ICON ), IMAGE_ICON, ICON_SIZE, ICON_SIZE, LR_LOADTRANSPARENT|LR_CREATEDIBSECTION );
But hIconImage is NULL after the loading.
Regards,
FarPointer

Your first parameter of the LoadImage is
(Taken from MSDN "hinst
[in] Handle to an instance of the module that contains the image to be loaded. To load an OEM image, set this parameter to zero."
so why do you use NULL? use something like AfxGetInstanceHandle()....

if icon is in resoruce use
LoadIcon(AfxGetApp()->m_hInstance,name icon);

Hey folks:
If you only want to have one instance of your .exe running, how can you detect that it is already running, and then exit gracefully?
(MFC is OK, but no .NET please), and I'm a noobster so please keep that in mind when answering :P

 Go look at the FAQs on CP. This is an old question and I am sure it is covered in one of them.

There are lots of ways of doing this. One is to use a mutex (see the CreateMutex API): You call CreateMutex with a unique name (a name which contains a GUID is the smartest choice) to create a mutex. Then if the call succeeds you call GetLastError and if it returns ERROR_ALREADY_EXISTS you're not the first one so you bail. There are ways you can do it using COM also.

I think any named kernel object will do, it does not have to be a mutex.
|
|
|
|
|
Yes, there is no need to use a mutex if you prefer some other option. As I said, there are many ways this can be done.
