I assume you have a member variable that has been subclassed to the control in question. This might have been done for you. Use the debugger to make sure that m_hWnd is not NULL prior to adding the sample text to the list box. If it is NULL, make sure that the resource ids haven't changed and that the control id is correct for the control. This often causes problems.

I'm looking for a "multi-slider" control that contains n (>= 1) knobs to allow for the definition of contiguous ranges. An example of one with 6 knobs would look like this:
(min)...|.......|..|....|.......|...|..(max)
1 2 3 4 5 6
A pointer to existing code would be much appreciated. Thanks!

Strange occurance ?
In one dialog, i call this
myDlg = new CmyDlg;
myDlg ->Create(IDD_DIALOG, GetDesktopWindow());
myDlg ->ShowWindow(1);
Now I have a thread running, if it receives a message, it'll sometimes popup a MessageBox window, but the MessageBox will be under everything. I want the message to popup ontop of everything.
If I call from the thread, with MessageBox(GetForegroundWindow(),...); It'll popup the message box, but then the application will lock.
Not sure what's causing it, and if I do MessageBox(NULL,...) it'll run fine except the MessageBox is under everything ..
?

I got it, just tagging MB_SYSTEMMODAL to the function.
Btw, why does it do that ?
|
|
|
|

Well not realy: MB_SYSTEMMODAL suspends all applications (equivalent to locking up all applications), until the dialog is close.
If you are using MFC, try: AfxMessageBox(...).
I have only used it few times my self, but it should set the hWnd parameter to your main application window or the currently active window in your application (or possibly NULL). If it works then single step into it and find out why.
MessageBox(NULL,...): Should popup the modal messagebox in front of all the windows, it has no parent (actualy that's not true, but the docs say it is) (It has always worked for me).
Search previously asked questions: Some one was having this same problem last week (my be some one knew what the problem was).
The (probable) reason no one has attempted to answer this question is that it does not happen. The only time I've seen this, is when a messagebox popups and the user does not close it, but clicks on the window that the messagebox is in front of (sending the messagbox to the background).

I have an application that was originally developed with Windows 98 ( yes, just recently bought new laptop with XP Pro). I have also occationally built the app. on my work PC which runs Windows 2000. No difference there. But when I now try to build with XP all dialogs and CFormViews come out wrong with static texts in shifted positions relative to edit boxes, etc. The environment is VC6.0 service pack 3.

No need to be . Win98 (?) and Win2000 (great stystem) have a lot in common, but that is where you should have seen problems (if any).
Each system may use a different default character set, which will affect any windows layout that resembles a dialog (that applies to internationalization as well). That means the static text bounding rectangle should be larger than the default size, which is based on the default font size at design time. (You might need to throw in some calculations as well.)
I recommend making a copy of your application and modifing it on XP so that it looks right. Then compare it to the original program (visualy), to see what the difference is. (That may be enough for you to figure out the problem.)

Thanks for the reply!
I found the cause of the problem. It is as simple as DPI (pixels, or dots, per inch). In my program I have used SepMapMode(MM_TEXT). In the dialogs and CFormViews there will be a mix of this mode and DLU (dialog logical units). The former is dependent on the device, the latter is calculated from the font size, which is device independent. Now, that is something to be about. I should of course have used SetMapMode(HI_METRIC), or some such thing.
My new PC has default DPI=120. By changing this to 96 (designated Normal by Windows) my program works fine.

Check your desktop display "DPI" settings. On some of the machines, you may be set for "small fonts", and on the other, for "large fonts".

Hello Experts!
I am able to retrieve all the profile properties for a user except the PR_MANAGER_NAME property. All of the other fields fetch fine. All the name, address, custom attributes.. you name it, they retrieve fine. The only one that fails is PR_MANAGER_NAME. This fails on all machines tested.
Below is my code (in abbreviated form, that retrieves a single property). You can plug this code into a simple Win32 project (that supports MFC) and it will build and run for you. You will notice about 1/2 way down where I set the property to be read:
//aSenderProps.aulPropTag[0] = 0x3001001E; // PR_DISPLAY_NAME <==== THIS WORKS
aSenderProps.aulPropTag[0] = 0x3A4E001E; // PR_MANAGER_NAME <==== THIS FAILS
Can anyone shed any light on why this is failing? Many thanks in advance!

How exactly is failing? Does it return an empty string, is the type set to PT_ERROR, is the return different than S_OK?

It turns out that I need to read the PR_EMS_AB_MANAGER object. Here is the quote I got from another forum:
You will need to open the PR_EMS_AB_MANAGER property as IMAPITable
(IMailUser::OpenEntry(PR_EMS_AB_MANAGER, &IID_IMAPITable, ...)).
You will get back a table with a single row (or no rows at all).
Read PR_DISPLAY_NAME from that table or grab PR_ENTRYID and call
IAddrBook::OpenEntry to get back IMailUser representing the manager, you can
then read PR_DISPLAY_NAME from that object.
.. now all I need to do is figure out how to do what is described above

Hi all,
I am working on an aplication where I will need to use a CTreeCtrl. However, I don't want to have the common tree look:
- --Root
|
- --Child1
| |
| - --GrandChild1
| - --GrandChild2
|
+ --Child2
Instead, I would like to use a competition bracket-like style:
- GrandChild1
|
-Child1 --
| |
-Root -- - GrandChild2
|
+Child2
It would be nice if the nodes were represented as shapes with the text inside.
I would like the nodes to have right-click functionality like addchild and delete and
deletechild[i]. I think I can add this functionality myself, but I need help with getting the tree to be laid out in a bracket style and with shaped nodes.
Does anyone happen to have code to do this? or can anyone show me how I would go about doing it?
Thanks a lot

The tree diagrams do not display like they are supposed to... I guess spaces aren't allowed... if you have questions about either diagram, please ask!

The normal CTreeCtrl looks like:
- --Parent
|
- --Child1
| |
| - --GrandChild1
| - --GrandChild2
|
+ --Child2
but I would like it to look like another version that looks like:
- Grandchild1
|
- Child1--
| |
| - GrandChild2
|
- Parent--
|
+ Child2
Thanks a lot,

I have Visual C++ 6 Standard and have tried to integrate the VC++ 2003 Toolkit compiler (ie. VC++ 7.1 Pro optimising compiler) and the Platform SDK with it, but I cannot get it to compile ATL/WTL/MFC projects (I just get a lot of errors). When I switch back to using the "bin" folder from VC++ 6 Std, the projects compile successfully.
Is it possible to do this, or is the VC++ 2003 toolkit compiler hard-coded not to compile ATL/WTL/MFC projects ?
If someone has got it working, I'd appreciate instructions on exactly how to set it up.

hi,
i need to draw a sin() function that move in the client area ( like the preformance of the CPU in the os' )
the grafh [the sin() func'] must have the ability to chang the frequency
and the amplitude.
