It's fairly easy: build a DLL with exports the

<a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/Shell/reference/functions/cplapplet.asp">CPlApplet</a>

function, rename it to have extension .cpl, drop it in the system directory and voilà you've got a new applet in your Control Panel.

Try inserting APIENTRY just before CPlApplet.

before adding APIENTRY ,I could debug the code but now no debug and the code just return 0 with doing nothing.

extern "C" LONG __declspec (dllexport) APIENTRY CPlApplet(HWND hwndCPL,UINT uMsg,LPARAM lParam1,LPARAM lParam2)

something else?
Thanks

Ummm... Sometimes it takes longer than desired to get these things fixed... Try removing __declspec(dllexport) (but keep APIENTRY!) and add a .DEF file (i.e. create it and add it to the project as if it were a .cpp file) like this:

LIBRARY      "MYFIRSTCPL"
DESCRIPTION  'My first CPL'

EXPORTS
    CPlApplet @1

create a text (letter) to be printed from a dialog box

Hello, In fact, I have a dialog box where I retrieve several information (name, address, etc), and I would like to create a letter (so a text document) using these informations and print it directly (no storage and differed print, but asking for printer ...).
The possibility to have different fonts/size in the letter, to be able to choose the printer, etc would be great.
Could someone indicate me the different steps (how to create document, how update it with variables linked to the dialog box, how ask for the printer, how to print it, how to change fonts, colors, etc) to arrive at this result .
At least a draft, i will look deeper by myself after.
Thanks in advance

Some other folk posted a message some days ago about using a hidden CRichEditCtrl for printing purposes. Doing a quick search on the net yielded this article. Also, creating a simple RFC on the fly is easy.

I have a very annoying problem, and I've got no idea how to fix it : when I type some code in Visual Studio, the parameters of methods, or the available methods of an instance don't appear !!

It used to work !!!

Anyone knows how to switch this feature on ?

Thanks !

Combo Box with Tooltip

Hi everyone. Is there existing source code, or perhaps someone could explain to me how, to allow a tooltip to pop up over a combo box when the user puts the mouse over the combo box? MS Word does this when the user puts the ouse cursor over the font size combo box on one of the control toolbars. I have a font size combobox on a control bar, and I want the tooltip to pop up when the user puts the mouse over it. Thanks in advance!

In CP there is article about List box with tooltip support,check it,they are the same.
You have to subclass,from CComboBox and ovverride some functions that you can see in that aticle.

This is the technique i use (this is probably an MFC-only technique):

Create the toolbar with a placeholder button at the position you want the combo box to be.
Give the placeholder button the same ID as the combo box.
Enter a description for the placeholder button. Put a newline within the description; all text after the newline will be the tooltip.
After the toolbar is created, modify the placeholder button to be as wide as you wish the combo box to be, and make it a separator.
Make the combo box a child of the toolbar, give it the same ID and position as the placeholder button (the ID bit is critical to having it work).
Set the owner of the combo box to be the window you wish to recieve combo box messages.

If the toolbar is in a CFrameWnd-derived window, you should be good to go. If not, you'll have to do a little extra work to handle tooltip notification messages, but otherwise it's pretty much the same.

good luck!

Override PreCreateWindow for main frame and set window position there.

I wanted my window to be topmost so i used setwindowpos()..

This can be done from PreCreateWindow using CREATESTRUCT::dwExStyle, WS_EX_TOPMOST flag.

with

ShowWindow(SW_HIDE);
SetWindowPos(.....);
ShowWindow(SW_SHOW);

Which flags are you using with SetWindowPos?
Either you use:

SetWindowPos(NULL, x, y, cx, cy, SWP_HIDEWINDOW | SWP_NOMOVE | SWP_NOSIZE); 
ShowWindow(SW_SHOW)

MoveWindow(...)
ShowWindow(SW_SHOW)

SetWindowPos(NULL, x, y, cx, cy, SWP_SHOWWINDOW);

I meant the nFlags parameter. If you supply SWP_SHOWWINDOW and then call ShowWindow(SW_SHOW) then you have two "show". My guess is that that is your problem. Have you tried the alternatives I suggested? Btw, with the third one, remove the ShowWindow call.

I had written SWP_HIDEWINDOW inSetWindowPos().
Ok,I tried with SWP_SHOWWINDOW & no ShowWindow(SW_SHOW).
Still there is no change..

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
