When you typically open Word, the cursor is selected to allow for immediate typing on the keyboard.
With a tablet PC, there is also a pen selection to where the user can "draw" on the screen with the stylus, instead of the normal cursor.
I am looking for a way to open Word with this pen selected as the default rather than the cursor.

Making a pointer array is basic stuff.
Look into your book where the new and delete operators are explained. Also check the chapter which explains constructors, and the answer to your question should be clear to you.
These are the basics for programming C++ so finding the answer on your own is really best for you in this case, just read these 2 chapters.
The only hint I'll give you is to use a parameter in the constructor and the elems will be a pointer in stead of an array. Have fun finding the answer, it should be quite easy with the hints I gave you and if you read about the points I mentioned.
Regards,
Davy

Hello
I want to build a multiband (from 60 Hz to 3 kHZ ) audio equalizer using Directshow and sample grabber.
1. I guess I must build band-pass filters ( I will work with FIR filters) to equalize sound.
Is there any sample or advice for that task ? For ex. what should number of taps in my filter be ?
2. Let's assume that I added ParamEq DMO to my graph. How can I change parameters for this filter ?
Regards,
Akin

Can anyone please tell me how to correct it.
Here is the code.
std::string strASCIIText;<br />
strASCIIText = "Hø";
But when i debug that i find that value of strASCIIText becomes"Hø", can anyone please tell me how to fix that.
This happens when i want to initialize std::string with extended ascii code.
Thanks,
Mushq

I have already explained to you the difference between ASCII and the extended version in this post[^].
I have already explained that the these extended codes display different characters depending on the code page being utilized. The debugger is interpreting the code as UTF-8 so displays the character à on your computer. Which by the way... displays correctly on mine. Probably because the codepage I am using is Western European Windows-1252[^]
Best Wishes,
-David Delaune

I created a dialog-based program, inserted a new dialog, placed a CMonthCalendar Control on the new dialog. I used the varavle wizard and created a varable for the CMonthCalendar Control. EVERYTHING worked when I checked it in Debug.
I then inserted a CListCtrl listbox, created a varable for it. I then compiled without any errors. I again checked the CMonthCalendar Control and found that I had NO hwnd, ie hwnd=00000000. Naturally upon the GetCurSel(CTime ct) I received a "Access Violation" because the first thing done is check for IsWindow() in MFC and naturally it didn't have hwnd.
Has anyone else had this or a simular problem with VS2008 Professtional?
I had no problem with this in VS2008 Professional BETA 2.

Did you call InitCommonControlsEx() to register that control's window class?
|
|
|
|
|
Here's the code from my "theApp" objerct:
INITCOMMONCONTROLSEX InitCtrls;
InitCtrls.dwSize = sizeof(InitCtrls);
// Set this to include all the common control classes you want to use
// in your application.
InitCtrls.dwICC = ICC_WIN95_CLASSES;
InitCommonControlsEx(&InitCtrls);
I don't know if this is right/wrong. It's what the wizzard put in the programs .cpp file
some more code:
CMonthCalCtrl m_cMonCtrl;
CListCtrl m_cLstCtrl;
DDX_Control(pDX, IDC_MONTHCAL, m_cMonCtrl);
DDX_Control(pDX, IDC_LOG_ENTRY_EDTLOG, m_cLstCtrl);
CTime ct;
/**************************************** ERROR *******************************/
m_cMonCtrl.GetCurSel(ct);// "Access Violation" error (no hwnd, ie hwnd=00000000)

Here's the code again:
void CEditLog::OnMcnSelectMonthcal(NMHDR *pNMHDR, LRESULT *pResult)
{
/**************************************** ERROR *******************************/
//LPNMSELCHANGE pSelChange = reinterpret_cast<LPNMSELCHANGE>(pNMHDR);
// TODO: Add your control notification handler code here
//m_cMonCtrl
CString str;
CString csFileName;
CString csTmp;
int nMonth, nDay, nYear;
nMonth = nDay = nYear = 0;
CTime ct;
/**************************************** ERROR *******************************/
m_cMonCtrl.GetCurSel(ct);// "Access Violation" error (no hwnd, ie hwnd=00000000)
it's called when the user selects a date in the control.

I just tried this (the only control on the dialog template was a Month Calendar) with VS6 and it worked fine. I suggest you do the same, and then start re-introducing your other code until the problem comes back.

Yes, I've done this several times. Still the same result if I also include a ListCtrl on the same dialog. Try doling so yourself: ie, add a listctrl then try to add column headers (Report View). either the MonthCalendar will throw an Access vioalation or the ListCtrl will!

Did it. No errors.

It has to be myh bad install then. I created another dialog-based project, put a MonthCal control and ListControl on the same dialog and this time the listcontrol can up with hwnd=00000000. (It was called before the monthcal control.)

If you care to send me your e-mail address via private reply, I'll send you my VS project for you to compare.

Okay: larryamillssr@hughes.net
By-the-way, I'd like to send you my complete project so you can check it out.(the project for checking for the error.) The original project compiled and worked correctly under VS2008 Pro BETA 2. This retail version has given me nothing but trouble from the start. And I can't get any help from microsoft. I think it didn't load something/or didn't merge something right. I've reinstalled it 4 times with the same results.
Like I said, the program was created under VS2008 APro BETA 2 and everything worked correctly until I installed the retail version.

David,
I'm having some trouble with sending you the project. Please be patient. I'll eventually fiquire out why my program (Outlook) is having trouble sending it to you.

Your ListControl and MonthCal control both had hwnd. However, I don't know if that proves anything or not. The program I am having this problem with Compiled and Ran as it was meant to do under VS2008 Pro BETA 2. It's this retail version that is having a problem with it. I was nearly finished with that program too!
That's why I asked if anyone else was having a problem with VS2008 Pro retail version.
