Start with that article (written by Tom actually, maybe he forgot that he'd written it?) that shows how to use your own class in a view. Then you can write a CListCtrl-derived class and use that for the view.

This is the only way I've been able to use a derived CListCtrl with a view in the past. However, I just tried to use it and it 1) doesn't compile without some tweaks and 2) asserts all over the place.

I'm thinking your only choice is something very manual, where you use a FormView, subclass the list control with your derived class and then manually handle sizing issues.

VC++6 ide question

how do you get the find box with the find next button to stay on top even after you've pushed the find next button, There's no pin to keep it there.

I've been wondering this for years now, thanks.

Use the Replace box instead! For some reason, the Find Next button in this dialog doesn't close the dialog.

ToolBar text with BTNS_SHOWTEXT

armentage29-Jul-03 6:55

I'm trying to put text into an MFC CToolBar, and am having problems with end of my tool bar getting cut off. What's happening is that app is computing the size of the toolbar WITHOUT the text, just the width of the icons/separators, so the toolbar ends up too narrow.

I'm using Visual Studio 6.0 SP5, with IE6.0 installed on my system. Here's the code I am using:

<br />
DWORD dwExStyle = TBSTYLE_EX_DRAWDDARROWS|TBSTYLE_EX_MIXEDBUTTONS ;<br />
tbar.GetToolBarCtrl().SendMessage(TB_SETEXTENDEDSTYLE, 0, dwExStyle);<br />
<br />
int index = CommandToIndex(IDM_CALCULATE);<br />
WORD dwStyle = tbar.GetButtonStyle(index);<br />
dwStyle |= BTNS_SHOWTEXT|BTNS_AUTOSIZE;        <br />
tbar.SetButtonStyle(index, dwStyle);<br />
tbar.SetButtonText(index, "Calculate");

Some info: BTNS_SHOWTEXT is NOT defined by the MFC/Win32 header files that are installed on my system. I had #define BTNS_SHOWTEXT 0x40 to get this to work. I found many references to it on MSDN, and google'd for its value. I understand it will only work on systems that have IE5.0 or better.

What I'm guessing is that the MFC CToolBar implements the CalcSize function using assumptions about IE4.0; rather than calling CToolBarCtrl::GetItemRect, its assuming the size of each icon by using its bitmap size + padding. The BTNS_SHOWTEXT option is new and the circa 1998 (IE4 was just released) MFC just doesn't know to deal with it.

Thing is, I can't find any threads or discussions on what to do in this situation. I can't find a place to download a set of Win32 headers that match the new ComCtl32.dll v5.8, or any sort of MFC patches to expore the v5.8 functionality to VC6.0

Any help would be greatly appreciate. I can't switch to VC.NET (as much as I'd love to) because my company likes to drag it's feet when it comes to upgrading development tools.

I wouldn't be surprised if your assessment is right, considering that MFC 6 is so old and pre-dates even IE 5.
As for getting the newest headers, download the Platform SDK (see the VC forum FAQ for details on doing this)

Do you happen to know if the MFC that ships with VC.NET has been imrpoved (updated) to expose more of the new ComCtl32 features? Maybe not this problem specifically, but how about images in CListCtrls or the new thumbnails view, etc.

Even more off-topic, is this one of the reasons everyone seems to be using WTL now a days?

Each Office application exposes a COM interface. Using automation, you should be able to do what you need.

May you say more clearly please. I know that this problem can be solved by COM. I know "Excel?.Dll" "MSWord*.dll" can use for programming. But I don't know all of its function. And how to open MS Office file without opening MS Office Application.

How do I group Radio buttons using the Resource Editor?

Re: Visual C++ Resource Editor

keegan29-Jul-03 5:48

in the dialog editor window thingy where you see the radio buttons, edit boxes, etc, right above the radio box is the Group Box Function. use that, and change the status of "Group" in the radio buttons properties to TRUE for the first radio button in the group.

if that makes any sense.

Thank You,
But their is not "Status" option in Visual Studio 6 Resource editor. Your help did show me the way. Select "Group" for the first control in the group and not selected in subsequent controls.

a group of radio buttons is defined by tab order, in which the first one has the "group" (and "tab stop"?) check box checked in the properties for the first checkbox button in the group you want to have.

It's not a visual group, more a logical grouping.

Welp its time to comment all my 10000000000 pages of cpp files, and i'd like to link to a certain area. Ie, i could say

"click here to go to this function"

and when they click on "here" it teleports them to the function source code.

Is it possible?

I don't know about in Visual C++ itself, but you can probably do something like this in doxygen.

CStringArray in a CList

Anonymous29-Jul-03 4:13

I have tried to create a CList of one/more CStringArray objects. If I try and add CStringArray to my CList I get the error:

error C2558: 'CStringArray' : no copy constructor available

Do I have derive from CStringArray and write copy constructor for my derived class? How come CStringArray does not already have copy constructor. Surely it knows the type of its elements so surely it should know how to copy itself?

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