You are loading the library to check if the riched20.dll is there correct? Now I have one more question. Have you been able to print that area correctly? If so, how? I'm trying to do that. The problem is that we don't know what the output device will be at the time of creation. Interesting twist huh?
Thanks again.

Use EM_SETTARGETDEVICE to set the target device. Then use EM_FORMATRANGE and EM_DISPLAYBAND to display the control's contents. See the MSDN article Q129860.

Thats the caveat Dave, we don't know what the device is when the use uses it! What I'm currently doing is pulling each line out, scanning for font differences and using the TextOut to draw the text. Problem is that the font that shows up on the screen (fitting inside of a box) is either bigger or smaller than what was on the screen.
Kind of an interesting puzzle huh?

Ok, I'm a tad confused at this point. Are you wanting to take text from a rich edit control and send it to a printer? It sounds like you need to use GetDeviceCaps() to make sure the target device is setup like the rich edit control.
|
|
|
|
|
Now I'm confussed?  How do you do that? See if the target device is set up like a rich edit? Am I getting too deep here? I wish I did know what the target device was when the users used it, but that is the requirement.

You have a rich edit control on a dialog or a form-based view. Yes? What are you wanting to do with the text in the control? As I understood your earlier post, you want to take the text in the control and send it to a printer. Yes?

I actually sits within an area on a scrollview. Kind of like a text box in word. Then when the time comes, draw the text to the printer or some other device.
Sorry for the confustion.

I want to output the text in a rich edit control (there are many on the same page) with the same format and fonts usage as in the Rich Edit control. I thought I could use the FormatRange, but since I don't know what the target device is when it is being used, I'm not sure if that would work. So, I was getting one line at a time, then spending time to scan character by character checking the fonts used. When the font changs, then I would save off the font and the text. I continue until the whole line is scanned and getting the height of the text to the baseline. Setting the output to use the base line as the y parameter and outputting it to the device. This is so ineffecient it isn't funny. Am I correct in using FormatRange? OR, could I use FormatRange along with DisplayBand to output line by line. Again, inefficient than doing the whole thing, but it would be better than doing character by character.
Thanks Dave.

I do something very similar. For a billing application I wrote, a number of users wanted "word processing", so I use a commentary window which is a richedit.
I use FormatRange to step through appropriately sized chunks of the richedit, by working out what printable space there is (in twips), and making repeated calls, to build up a list of ranges (since it could be multi-page), more efficient than scanning the control's contents for changes (although it's similar to what the control is probably doing internally).

Did you use the SetTargetDevice to make it WYSIWYG? The problem I'm having (or maybe I'm just making it harder than it really is) is that I don't know what tht output device will be at the time they enter in the data.
Thanks for the Reply and info Steve.

I have tried using the SetTargetDevice with the width of the window (in TWIPS) and getting the printer DC. The text is coming out in the proper format (line breaks and all), but the graphics that surround that are not.
As an example, I place a line just to the end of the line, then do a print preview and the text extends past this line. I can send the test code that I'm playing with so you can see what I'm seeing.
I am also getting conviced to do WYSIWYG, I really do need the output device to do the formatting. With out the device, what I need to do is seeming more and more impossible without a lot of fudging!
Thanks you Guys.

Hi!
I need to exchange data from MFC Dialog A to MFC Dialog B. What I tried is using Messages (like WM_COPYDATA, or user messages (registered/Not registered)) to pass an address of a struct where I have put ma data, but without success. The message never arrives, and I think the problem is that I do not have the handle of B in A, and the ::SendMessage (Or PostMessage) needs a hWnd as first parameter. HWND_BROADCAST instead did not bring anything ...
I only need to pass 1 struct, so I do not want to Use a CMemFile...
Please, CPians, help ... many thanks...

Is this struct created on the heap or the stack?

You are correct. Without a window handle, Windows does not know to whom the message is to be delivered.

on the heap.

Any idea how to get that handle ? Is there any simpler way that using EnumWindow or FindWindow ?
Thanks for your answer.

There are lots of simple ways. The question is which is the better (i.e., more reliable) way? Read this article on using FindWindow() in the context of controlling the number of instances an application allows.

So I am writing an editor for a 3D space game with direct X placed inside a Child Frame.. My problem is that. I need to be able to get the title bar info to adjust the size for picking. This will allow me to correctly send mouse coords to pick models in 3d space.
Basically I just need to add the hight of the title bar to the y mouse coord.
I am tryign to use:
TITLEBARINFO ti;
GetTitleBarInfo(&ti);
However TITLEBARINFO is not valid in MFC as far as I can tell. I tried including winuser.h but as usual cant include windows.h in an mfc project. How can I get the size or how can I get the TITLEBARINFO structure in MFC??
|
|
|
|
|
it has to be defined, because
BOOL GetTitleBarInfo(
PTITLEBARINFO pti
) const;
is defined!
Don't try it, just do it! 
|
|
|
|

Why can't you include windows.h in your MFC project? I can...

A professor knows a lot about little.
I know everything about nothing.

I use it return value ,there is a cmpile error:
Return Values
If the function is successful, it returns NERR_SUCCESS.
If the function fails, the return value is one of the following error codes.
Value Meaning
ERROR_ACCESS_DENIED The user does not have access to the requested information.
NERR_InvalidComputer The computer name is invalid.
ERROR_MORE_DATA More entries are available with subsequent calls.

Please rephrase your question, so that one can understand what you want to ask.
Who is 'General Failure'? And why is he reading my harddisk?!?

Are you getting a compiler error, or a runtime error? You indicate a "cmpile error" but give no other information.
ERROR_ACCESS_DENIED and ERROR_MORE_DATA are defined in winerror.h.

this question how u posted it cant be answered!
try again!
Don't try it, just do it!

I am sorry for my poor english,thank for your help,I search MSDN,can't find NERR_SUCCESS and ERROR_ACCESS_DENIED defined.
I use like this :
if (NetUserEnum(.....) == NERR_Success )<br />
..........
The compiler complain as following.
C:\MYAPP\VCAPP\GetUser\GetUserDlg.cpp(111) : error C2065: 'NERR_Success' : undeclared identifier

Sure, because the name of the constant is NERR_SUCCESS.
See the difference? Character case does matter!
