Just telling you that you have to do all hooks in a DLL if you want to catch when a key is pressed while your app is in no focus! Smile | :)

Richard Jacko & Rickard Andersson & All,

First, thanks for the reply. I think I'm headed in the right direction.

Secondly, I'm very new to Windows programming so I'd like to apologize for my "Windows ignorance" Roll eyes | :rolleyes:

. Please bear with me...

From reading the docs on SetWindowsHookEx, I assume that I want to set the idHook = WH_KEYBOARD, right? Then, I have to write a DLL with a procedure that will handle the message (which I've never done).

Is this all correct? Confused | :confused:

Thanks.

Marcus

Need help on ShellExecute Print verb

I have the following code that will attempt to print various files without the need of Print Previews etc.

temppath = patharray[0].Left(patharray[0].ReverseFind('\\')+1);
temppath += "ReportFiles\\My file.html";
ShellExecute(NULL, "print", temppath, NULL, NULL, NULL);
filestring.Format("Production sheet has been printed.", tempfile);
m_misc.InsertItem(12, filestring, 1); UpdateWindow();

However, when the print dialog appears I get the following error message appearing in a message box:-

"Cannot find the file 'D:\Test\ReportFiles\My file.html' (or one of its components). Make sure the path and filename are correct and that all required libraries are available."

Despit this message the file is found and prints OK!?!?! Is there any way to avoid this message from being shown.

Also, I would like to not have to show the print dialog box so that it will automatically print on completion of a task. Is there any way of doing this and also to print multiple copies of the report.

Any constructive suggestions would be greatly appreciated.

Cheers,

James Smile | :)

Ok I'm going to take a couple of guesses Smile | :)

1.)
ShellExecute uses the default file association in your case "html" to open the document.
So in effect you are probably using your browser to print for you. And probably you are using IE4+ to do your dirty printing.
Check to see it's just not your PC that has this problem,
(Us coders are quite likely to abuse file associations on development boxes) Smile | :)

So maybe your code will run OK on a neighbours PC but not yours.
2.)
Consider changing your NULL paramaters to empty variants, And turn off the "Active_Dektop"
3.)
Try using OLECMDEXECOPT_DONTPROMPTUSER
as a paramater, I think its the third one ?
4.)
Make sure your Browser can actually print without errors ocurring.

Which database should i use ? The database must be able to guarentee access for more than one user.
