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.

Re: Combo Box with Tooltip

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.

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

Replace

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..

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

20-Feb-02 22:05

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.

You get automatic linking of projects thru the dependency check only when the project depended on is a library (static or a DLL). Otherwise, the dependency tool just checks that relative building dates are consistent. If you want to have some of the source code for app A into app B, you have no choice but to add the .cpp files to the new project.

Even though they're dependant on each other, they are still separate projects. The dependancy options in the IDE simply allow you to ensure that one project is up to date before the other is compiled.

This is great if one project is for example a DLL or a LIB that the other depends on.

From what you said, it looks like you want to use a class from one project inside of another. There are a number of ways to do this:

1. If the class in inside of a DLL and exported, you can use it from there.

2. You could use the class in source form. You need to add the files from the class to your project (cpp and h files)

I think that (2) is what you want to do. In this case, your class project does not need to be a dependancy of the other project, because you are using source code, not compiled code. therefore it doesn't matter whether it's been compiled in one project or not.

CEdit: right aligned?

Rüpel20-Feb-02 21:09

Rüpel

20-Feb-02 21:09

ok. the following scenario: i have an edit-ctrl (CEdit). i want to show a path to a file in this edit-field. as you all know, paths become very long and almost never fit into the control. the only thing, the user reads is c:\program files\mytool\... and the interesting things (at the end) are hidden each time i change the text in the control. just because the text is scrolled to the very left, after UpdateData(FALSE).

when i check the "right-aligned" style in the dialog-resource-editor, text shorter than the control-area is indeed aligned right, but if it gets longer than the edit-ctrl-rect, it is aligned left again. Frown | :(

- besides: it really looks ugly when printing the short path rigth-aligned. so this option doesn't work for me.

does anyone know the mysterious function: CEdit::ScrollToTheVeryRightSoYouSeeTheEndOfTheString()???

or does anyone have an idea for a workaround (some HSCROLL-thing or whatever)

thx in advance

How about

<br />
CEdit::ScrollToTheVeryRightSoYouSeeTheEndOfTheString<br />
{<br />
   CString cs;<br />
   int len;<br />
   GetText(cs);<br />
   len = cs.GetLength();<br />
   SetSel(len, len);<br />
}<br />

didn't try it out so it may not work.

{
    CString str;
    edit.GetWindowText(str);
    int nLength=str.GetLength();
    edit.SetSel(nLength,nLength);
