Re: It printed the same without Header Columns

So you see the frame, then a space where the header should be, and then the list contents?

Hi Shog,

Not like you said: Imaging you see the ListControl on the Monitor Screen with its Header Columns & its contents (as it is supposed to be)! Then when I print, it printed just like that ... except there is no Header columns

Hints: If you use in MFC a ListControl dialog, then goto its property, select Style --> Select View --> Select "Report"! Then you should see a ListControl with a Header Column (default title "Color")

***> If in the Style property, you check "No Header column" option then that Header column row ("color") disappeared!

My print out just do like that (even I "did not" check the "No Header column" option!

I hope this Hint will explain what is my problem!

Thanks,

Replace all the print lines you have now with one that combines the flags:

{
    int oldMapMode = dc.SetMapMode(MM_ISOTROPIC);

    CSize ptOldWinOrg = dc.SetWindowOrg(-30, -30);      // XY LeftTop position
    CSize ptOldWinExt = dc.SetWindowExt(1, 1);
    CSize ptOldViewportExt = dc.SetViewportExt(4, 4);	          

    // print list ctrl
    m_report.Print(&dc, PRF_NONCLIENT|PRF_CLIENT|PRF_CHILDREN);
}

This will work. BTW: you may want to play with your size calculations a bit - the list prints fairly small...

Regions

Whats the best way to keep track of any number of regions at one time so that I can move them when ever I need to? The number of regions I'm dealing with can be any number.

Shog⁹19-Jun-02 18:11

That's sort of a broad question... You could use an array, a list, a map... It really depends on what your needs are in storing and retrieving them.

Well what I'm trying to do is create some regions that
I will paint a bmp into. Then I need to move them based on the user's selection and their mouse click. Doing all that I know how to do. Since their can be any number of regions at any given time which is pretty much random, keeping track of each one is the problem - I knew I'd hate programming graphics!

What I'm thinking, off the top of my head, is defining a class say

class CMyObject
{
   CBitmap bitmap;
   CRect bmprect;
   float iXAxis;
   float iYAxis;
};
CArray < myobject, myobject > m_myarray; //rather use STL

Question is how do I get the bmprect, bitmap, iX and YAxis and will it be different for each myobject that is created. Eek! | :eek:

So, these will all be rectangular, but possibly rotated? I guess i still don't really understand what you're trying to accomplish... Confused | :confused:

They will each take on a new position within the client view depending on where the user will move them. Just like those 2D games that move sprites over the top of a background. I need to keep track of each object so when it moves to a new location within the client view, just grab whats behind that region paint that piece then repaint the object in it's new location. This way I can test if a point is in a region and adjust the mouse cursor. I'm sure it's the obvious easy thing I'm missing. Smile | :)

Jay Beckert22-Jun-02 5:36

It was the obvious and basic programming design. It's as easy as defining a structure of the data including the HRGN and storing the structs in STL or CArray or what ever you choose. Then traversing that list checking to see if a point is in a region. I always make it complicated to later realize it's not as hard as it seems. Make sense?? Unsure | :~

HtmlHelp

19-Jun-02 13:59

Hi,

I have succesfully compiled my project in debug mode which extensively uses HtmlHelp calls.
Of course I included "HtmlHelp.h" in StdAfx.h and linked against "htmlhelp.lib" in both debug and release mode.

Now I switched to release mode and was quite surprised:
All HtmlHelp() calls were recognized as unknown.

Confused | :confused:

Thanks for your help.

Yes, absolutely.
In debug mode it compiled and run (!) OK.
I switched on release mode and all these calls

HtmlHelp(m_hWnd, "c:\\x\\uploads\\help\\eehelp.chm::/main.htm",HH_DISPLAY_TOPIC, NULL );

were not compiled:

C:\x\Source...cpp(334) : error C2065: 'HtmlHelp' : undeclared identifier
C:\x\Source...cpp(334) : error C2065: 'HH_DISPLAY_TOPIC' : undeclared identifier

again: in Debug mode it not only compiles it even runs well...

Looks like you may have added the the HtmlHelp include and library paths for the "Debug" configuration only.

More Registry questions

Hi,

I've noticed a lot of questions dealing with the registry. However, none of them seem to relate to my particular problem.

I need to specify exactly where my program's data goes. My problem is that when you call SetRegKey(), it automatically makes a folder for your program within the folder that you specified using SetRegKey() and I don't want that. I wish to put my data in another program's folder.

Thanks in advance,

I hate to be slow, but could you give an example of the RegCreateKeyEx (I've not looked at the others). One of the "out" parameters confuses me.

Never use KEY_ALL_ACCESS! If you do, the call will fail on NT if the user is not admin. If you need full read/write privs, use KEY_READ|KEY_WRITE instead.

CDialog & Multithreading :: MFC

Selevercin20-Jun-02 5:12

Selevercin

20-Jun-02 5:12

Ok, it's all looking good and better. I used Michel Dunn's idea. So this is my code:

        HKEY hKey;   
	DWORD dwDisposition;   
	RegCreateKeyEx(HKEY_CURRENT_USER,"Software",0,"",REG_OPTION_NON_VOLATILE,KEY_READ|KEY_WRITE , NULL,&hKey,&dwDisposition);
	AfxGetApp()->WriteProfileString("Cloaked Chat", "Test", "Test");
	RegCloseKey(hKey);
</code>

It all compiles error free, but do I need to set some values for the "hKey" and "dwDispostion"? When I ran the above code, nothing happened. Shouldn't it have made a folder called test with the string "test" inside the folder "Cloaked Chat" of the software folder?

Thanks,

Hi.

I have a class derived from CDialog for a dialog box. I implement a worker thread. I would like to post and/or send messaged directly to the dialog box class instead of going to main frame first. Is that possible?

Thanks,

Yes. CDialog is derived from CWnd. Thus you can use CWnd::PostMessage

Okay.

I called PostMessage() with m_hWnd. However, the compile responded with an error that m_hWnd is unknown. What do I pass to PostMessage() such that the dialog class will handle the message?
