You must add the TTS_BALLOON style to your CToolTipCtrl object.

m_pToolTip.Create(this, TTS_BALLOON);

May be you need to define this style

#ifndef TTS_BALLOON
#define TTS_BALLOON 64
#endif

Or you can look my class CPPTooltip Big Grin | :-D

Best regards,

Creating VC6 compatible library with VC7

Hi,
I'm working on a SDK for a program I have done and I have problem using the static library I provide with VC6. The library is build using VC7. So far my searches has been unsuccesful. Has anyone else found solution for this?

When I was migrating from VC5 to VC6 I remember there was a compiler switch to make VC5 compatible static libraries. I dont remember wich one it was though.

I made a test lib, and tried to use it with VC6 and I got for example following errors in the linker:

debug build:
corelibd.lib(Vector3C.obj) : error LNK2001: unresolved external symbol __RTC_CheckEsp
corelibd.lib(ControllerC.obj) : error LNK2001: unresolved external symbol __RTC_Shutdown
corelibd.lib(TimeSegmentC.obj) : error LNK2001: unresolved external symbol __RTC_InitBase
corelibd.lib(TimeSegmentC.obj) : error LNK2001: unresolved external symbol @_RTC_CheckStackVars@8

in both debug and release:
corelibd.lib(ParamI.obj) : error LNK2001: unresolved external symbol __ftol2
corelibd.lib(KeyC.obj) : error LNK2001: unresolved external symbol "void __cdecl operator delete[](void *)" (??_V@YAXPAX@Z)
corelibd.lib(KeyC.obj) : error LNK2001: unresolved external symbol "void * __cdecl operator new[](unsigned int)" (??_U@YAPAXI@Z)

For me it looks like the standard library is different in VC7. Any ideas how to overcome this?

using CTreeCtrl with a CObArray

I have written a small program that inserts items into an array and then uses the array to create a tree, problem is i don't know how to relate the tree to the array once it has been created.

ie.
a tree with 3 Name items, relates to an array with 3 name and address items.
I want to be able to click on the 2nd name and return the 2nd address.

If anyone could help with the function call to get an integer value for the selected item it would be great, or some casting work around.

Thanks in advance

The CTreeCtrl provides a DWORD value associated with each tree item. You can set this value with whatever you want and retreive this value later using the functions:
BOOL CTreeCtrl::SetItemData(HTREEITEM hItem, DWORD_PTR dwData)
and
DWORD_PTR CTreeCtrl::GetItemData(HTREEITEM hItem).
In your case you should set the item's data with its corresponding array index. You may even store in the item's data the address of the object held by the CObArray directly.

thanks,
not sure how to implement that in the code i've got to be honest..
Basically the important line i have is:

m_tTreeCtrl.InsertItem((versionPtr->GetVersionLabel());

Would it be wise after each insert to get the tree height, return that h treeinfo, then update it?

Also, is there a way to cast a DWord to an int? DWords are far too accurate for what i need.

Cheers

Pardon me, I cannot undestand this line of code (do not know what is the type of versionPtr).

To demonstrate, I will assume that versionPtr is an object of type CMyObject and the member function GetVersionLabel() returns a string of that object contents. And finally that we have a CObArray named objArr containing objects of type CMyObject.

Using this assumption, this is how to link the tree items to the array:

int arrIndex;  //this should hold the index of the object
.
.
//inserting the object number [arrIndex] into the tree
CMyObject * pMyObj = (CMyObject *)objArr.GetAt(arrIndex);
HTREEITEM hItem = m_tTreeCtrl.InsertItem(pMyObj->GetVersionLabel());
//now we set the item's data
//BTW, DWORD is a #define for usigned int
m_tTreeCtrl.SetItemData(hItem, (DWORD)arrIndex);
//now the data is set
//next is how to retreive it
.
.
CMyObject * pMyObj;
//where hItem is the handle of the tree item
int index = (int)m_tTreeCtrl.SetItemData(hItem);
pMyObj = (CMyObject *)objArr.GetAt(index);

This sample store the index of the object in the array, a better approach is to store the address of the object itself. In this case, the item data set line would be:

m_tTreeCtrl.SetItemData(hItem, (DWORD)pMyObj);

and the item data retreival line would be:

pMyObj = (CMyObject *)objArr.m_tTreeCtrl.SetItemData(hItem);

I hope that is what you want.

WM_CTLCOLORSTATIC handler blacks checkboxes

Jared McIntyre22-Mar-03 7:58

Jared McIntyre

22-Mar-03 7:58

The code snippet causing the problem is the returning the NULL_BRUSH to stop the backgrounds from painting themselves:

SetBkMode((HDC)wParam, TRANSPARENT);
bHandled = TRUE;
return (LRESULT)GetStockObject(NULL_BRUSH);

The statics all work fine, but the checkboxes are painted with an entirely black background. Is there a workaround for this (I need the checkboxes to not paint their background as well)?

One solution is CListView. You can derive a class from it and modify your class as you see fit.

you have a create a pretty advanced listview to implement Outlook like listview features. use of CustomDraw() is necessary to change item font etc. check out the listctrl and listview articles here.

Read up on the accessibility interfaces, which are designed for just this purpose. Run AccExplorer9x or AccExplorer32 (for 9x/NT respectively) in the PlatSDK to see a sample app that uses the interfaces.

MDI - Dialogs - Cascade - Problem!

Nirav Doshi22-Mar-03 3:32

Nirav Doshi

22-Mar-03 3:32

Hello,

I'm making a MDI application which has a lot of modeless dialogs used as input-forms.

The problem I have with them is each newly opened dialog overlaps the previously open dialog. I want the user to be able to cascade/tile the dialogs.

Queries:
(1). Is there a way that I can explicitly make them the children of my MDI. And if I can do this, will the CMDIFrameWnd::MDICascade() or CMDIFramWnd::MDITile() work to cascade/tile them. Cry | :((

(2). Or can I use some other function which could cascade/tile the dialogs for me?... Confused | :confused:

... Or am I required to take care of positioning each dialog properly below the previously opened one?? Cry | :((

Thanks,
Rgds,

Nirav Doshi

I suspect you'll need to do this manually by keeping track of the position of the most recently displayed modeless dialog. Then, offset each new one by (nOffsetX, nOffsetY), where:

nOffsetX = GetSystemMetrics (SM_CXSMICON);
nOffsetY = GetSystemMetrics (SM_CYCAPTION);

printf and unsigned char

Hi all

How can I print unsigned char's to the console? I compile with the "default unsigned char" option as this has to run on Linux, but in Windows it just spits out garbled characters.

Thanks Smile | :)
