Wrap toolbar to keep all buttons visible

Hi all,
I'm really tired of looking for the solution of this annoying problem:
I have MFC application with CToolBar. In fact, I have CReBar and two CToolBars in it. I display few buttons with text in these toolbars (in single line). When user changes the size of main window and the width is not enough, I want toolbar to automatically wrap to more rows so that all buttons stay visible.

I don't want to use chevrons or floating toolbars. I create my toolbars with TBSTYLE_WRAPABLE and I tried to call SetRows(...), but it had no effect. Yes, it created as many rows as requested, but all buttons stayed in the first row even though if the size was too small to show them all.

Thank you all for any suggestion.

I seem to recall that toolbar button wrapping only occured at separators. Does it wrap if you add a few separators?

I tried that but no change. In fact, the toolbar gets wrapped when the size is too small, but it wraps to maximally 2 rows for me, although I call SetRows() with higher argument. Thus I think I'll have to get rid of it by writing my own code for wrapping the toolbar, since I haven't found any example on the web which uses toolbar wrapping for docked toolbar Sigh | :sigh:

Hi Im a c++ beginner, I was wondering if someone could help me with using pointers and triangular arrays. I would like to know how to define them correctly, accesing them and finally printing them with a for cycle. D'Oh! | :doh:

thanks!

links to faqs and tutorials are also greatly appreciated;)

Here is one solution.

char ***pArray = new char **[1];
pArray[0] = new char *[1];
pArray[0][0] = new char[32];
...
delete [] pArray[0][0];
delete pArray[0];
delete pArray;

ok, now how would i point to a specific direction and print that? lets say^i have a an array[7][20][50]; and i would like to print it by pointers, how would i do that? or if i would like to print all rows position five etc...
thanks for your time Laugh | :laugh:

int *iArray;

iArray = new int [7][20][50];

// set values here

for (int x = 0; x < 20; x++)
{
    for (int y = 0; y < 50; y++)
    {
         // however you want to print... 
         // i.e. cout << iArray[5][x][y] << endl;
    }
}

Hope that's helpful.

FindWindow

If I wanted to find all the child windows on a dialog that were edit controls should I be able to use the following code

FindWindow ("EDIT", NULL);

If so should this code work in the first WM_PAINT message that a dialog receives? I ask because I try it and when it executes it returns NULL. I do have edit controls on my dialog. Any help is appreciated. Thanks.

FindWindow() won't work. Use EnumChildWindows() and in the callback proc inspect the window class and see if it is an edit style. See: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/WinUI/WindowsUserInterface/Windowing/Windows/WindowReference/WindowFunctions/EnumChildWindows.asp[^]

Thanks for the information. One question...how do I inspect the window class to see if it's an edit control? How do I get the window class information from the hwnd value? Thanks again.

Try:

TCHAR buff[ 32 ];
        GetClassName( hWnd, buff, sizeof( buff )-1 );
        if ( stricmp( buff, "edit" ) == 0 )
              ;  // we have an edit control

Custom Control & Dll Hell

ronhash17-Apr-04 6:09

17-Apr-04 6:09

Hi,
I have the followings:
1. A Dll with a custom control (ControlDll.dll)
2. A dll with a dialog using the custom control (DialogDll.dll)
3. An exe that uses the dialog from DialogDll.dll

The control is register nicely like all custom controls using AfxRegisterClass...

When i run the exe, it failed (the dialog was not displayed), what i did is the following:
Checked teh 'no fail create' to see where it failed, and found out it could not find the control from the ID while in 'PrepareCtrl' of the DDX_Control of my custom control.

I then created another dialog, this time in the exe, which uses the same custom control from the ControlDll.dll, and it worked!

It seems that the nesting of dll within dll, and the custom control registration some how got lost Frown | :(

Any help will be wolcomed Rose | [Rose]

if you use windows api functions but i am not shure what classes and functions you have because you include mfc library.

One possible solution is RegisterShellFileTypes().

I can't get to my Visual Studio right now, but i had the same problem. there's a function of CWinApp called enableShellOpen or something like that. put that function in your app's initinstance function and it should work.

If it's broken, I probably did it

2nd, first row on the right, which is the main view class has a ScrollView.

3rd, second row on the right, has a FormView.

I need to capture the mouse click and movement on the 2nd window and display the coordinates in the edit boxes in 1st window.

Can anyone help

One solution is to add a message handler for the mouse move message in the view class.

What are the steps to save the content of the CDC to the Bitmap file?

What are the steps to save the content of the CDC to the Bitmap file?

Well going through the MSDn and web articles i found some of the handy tools that are used for saving the content of Memory device context to bitmap file are:

1.0 Fill the BITMAPHEADERINFO structure
2.0 uSE THE GetDIBits() function
3.0 Use of CreateDIBSection to write

Problem Statement: I am having a global Memory device context. In a function i am initialising it as Mem. DC by calling API -> CreateCompatibleDC().
All the drawing stuff is drawn to it.

Now on Save i have to save the content of the MemoryDevice Context ( MemDC) to a Bitmap file.

Any solution,idea and guidelines to do this.

Why sometimes when i press . or -> the intellisense will pop-up a menu, but other times it does not. Is there a problem with vc++6? I'm definitely sure that particular object has that member function, but intellisense fails to bring the pop-up menu, all options are enabled btw.

Anyone experienceing same prob like me?
