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

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 !

Close VS, delete the projectname.ncb file in the directory where you have your project, and start VS again...

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);

Fredrik Skog21-Feb-02 1:16

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..

It seems to work fine for me. Have you tried it the way Alex Farber described?

Put this code in your OnCreate of MainFrame not PreCreate

SetWindowPos(&wndTopMost, 0, 0, 0, 0,  SWP_NOMOVE | SWP_NOSIZE);
ShowWindow(SW_SHOW);

OpenFileDialog in MFC

20-Feb-02 23:37

Hello,

I want to open a dialog box openfile but I don't know how to make it open always in the same directory (the directory where the .exe is), in a MFC project of course Smile | :)

Thanks.

I guess you're using CFileDialog, right? If so, then between the construction of a CFileDialog (let's call it dlg) and the line to dlg.DoModal() set dlg.m_ofn.lpstrInitialDir to the path of your exe. This path you can obtain with ::GetModuleFileName(NULL,...), stripping the .EXE file name out of the result (leaving then only the path, which is what you want).

Hi !

It´s possible to convert from OLE_HANDLE to a normal HANDLE ( for example HENHMETAFILE).

What´s the difference between a Handle and one OLE_HANDLE ?

Thanks in advance, Bye !

Project dependencies

I have a project which I added to another project in an effort to make the new project dependent on some of the classes there. In VC studio, I check the box so that the project is dependent on the new project. I added the header into the old project for the class I want to use but I get linking errors.

What am I doing wrong? I do not want to always add the classes I write into every project each time.

Thanks in advance. I have received so much help lately and appreciate it very much.
