previous versions of MSDN library included specification of BIFF format used by Excel, but i think it's not there anymore.

Counting characters in a buffer

Ok im trying to count the characters that i have loaded into a buffer i have set up the following function

void countchars(char *buffer, int *count)
/*Counts the number of characters in the text file */
{
int i,counter;
char cdata;
count['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z'];
do
{
{ for(cdata='A';cdata<='Z';cdata++)
if(buffer[i]==counter[count])
{
count++;
}

i++;
}
}while(buffer[i]!=EOF);
}
I am calling this function using the following code:

countchars(buffer,cdata);
printf("\nDistribution of letters in %s is:",fname);
for (c='A';c<='Z';c++)
{
N=cdata[c]+cdata[tolower(c)];

printf("\n'%c' %4d: ",c,N);
for (i=0;i

How to ignore Window activate ?

rrrado10-Apr-03 2:19

10-Apr-03 2:19

My application creates modeless dialog (in separate thread). The problem is that after creating of window system activates it and will put it foreground. How to create it without setting it active ?
How to restrict this window so that could be activated only by user ?
I tried to do this :

OnActivate(UINT nState, CWnd *pWndOther, BOOL bMinimized)
{
  if (nState == WA_ACTIVE)
    if (pWndOther)
    ::SetActiveWindow(pWndOther->m_hWnd);
}

But pWndOther is always NULL.
Any ideas ?
Thank you

First create the Dialog that you want with the resource editor.

BE CAREFULL YOU MUST REMOVE THE "Visible" style from ("More Styles") in the dialog properties.
OR YOU WILL GET A CRASH.!!

Then you must Create a new Class Inherited from CDialog.
Lets say

CUpdateDialog :: public CDialog

with a resource template.. (the dialog editor);

then Create a variable (Object) of the new class.

Lest say

CUpdateDlg m_UpdateDlg;

then go ....

m_UpdateDlg.Create (IDD_UPDATEDIALOG,this);

// This will actuallly do the trick!
m_UpdateDlg.ShowWindow (SW_SHOWNOACTIVATE);

Sorry about previews post...

You must also disable the "Desabled" style from "More Styles" in the resource editor and use this

m_UpdateDlg.ShowWindow (SW_SHOWNA);
m_UpdateDlg.ModifyStyle (WS_DISABLED,NULL,0);

instead of

m_UpdateDlg.ShowWindow (SW_SHOWNOACTIVATE);

Thank you very much ! Rose | [Rose]

I also have idea about DISABLED, but i didn't try it, i thought it won't work Smile | :)

BTW your solution works so that it won't steal focus, but anyway will create window in z-order higher than parent window (althought it is created like child of desktop window).
So I improved that to this :

m_dlg.Create(IDD_MANUAL,CWnd::FromHandle(GetDesktopWindow()));
::SetWindowPos(m_dlg.m_hWnd,AfxGetMainWnd()->m_hWnd,0,0,0,0,SWP_NOMOVE|SWP_NOACTIVATE|SWP_NOSIZE|SWP_SHOWWINDOW);
m_dlg.ModifyStyle(WS_DISABLED,0);

thank you again

typedef declaration

Hi !

I have a class named CGroup in a standard couple of file .cpp and .h, and I'd like to use a STL vector of CGroups in a structure.
So I typdefed it in stdafx.h (as explained in a CP article about using STL ) like that : typedef vector<CGroup> tv_Group. The problem is, the compiler is unable to find the "size" of a CGroup class, since the typedef occurs before the class declaration, and therefore throws an error.

I've also tried

class CGroup;
typedef vector<CGroup> tv_Group;

unsuccessfully.

I can remember having seen a post here in the forum recently about exactly the same problem, but I have forgotten the proposed solution Roll eyes | :rolleyes:

(Only to say, there _is_ a way to do it).

Thanks for any help.

what compiler error exactly do you get?

group.h must be included before typedef. forward declaration "class CGroup;" is not enough because compiler can't deduce the size of CGroup from it. it works if you have a vector of pointers to CGroup:

class CGroup;
typedef vector<CGroup*> tv_Group;

also, i would put the typedef in group.h instead of stdafx.h

hope this helps

Hi,

What could be the possible causes for a dragand drop operation to fail. I've used a COleDataSource Object and Initiated a drag operation with the COleDataSource's DoDragDrop method. I find that it has been returning from the ::DoDragDrop( Win32 API) instead of going into a loop. any help would be greatly appreciated. thanks in advance

Vijay.

I don't know if you have some money to pay for a SDK, but I know that Golden Hawk Tech. offers a C++ SDK to write very much formats. But as I mentioned it's quite expensive Unsure | :~

See http://www.goldenhawk.com/cpp.htm for details.

Nero also has an SDK. I think it's free.

Not quite. It needs Nero installed to run so it's not really "free"....

What does it mean ?

Hi, can someone help me understand what is being done here ? This is a code snippet from a Visual Studio Add-in project, and i have a few questions about it (after the sample).

HRESULT CCommands::Function(IDispatch* theDocument)
{
	AFX_MANAGE_STATE(AfxGetStaticModuleState());
	CComQIPtr<ITextDocument,&IID_ITextDocument> pActiveDoc(theDocument); 

	if(pActiveDoc == NULL)
		return S_OK;

	CComPtr<IDispatch> pDispTextSel;

	pActiveDoc->get_Selection(&pDispTextSel);

	if (pDispTextSel == NULL)
		return S_OK;

Maybe i am in the wrong forum, and this is all trivial ATL/COM stuff that i lack Blush | :O

. Sorry if the questions are dumb Unsure | :~

.

1.What is pActiveDoc ? A pointer on the Idispatch *theDocument ?.
2.Where can I find the description of the get_Selection method ?
3.Where can I find the descrition of the method available for pActiveDoc ?
4. What is AFX_MANAGE_STATE(AfxGetStaticModuleState()); being done for ?

Actually, what I'm trying to do is get the filename of the active file in the Visual C++ editor...I was looking at another Add-In src to try and understand how this functions, but this is all not as easy as I thought Roll eyes | :rolleyes:

1. pActiveDoc is a smart pointer to theDocument (wraps the pointer and takes care of object reference counting). since there is the Selection property, i guess that it is really a TextDocument object of DevStudio.

2.
Selection Property

Applies to: TextDocument object, TextWindow object

Gets the TextSelection object, which represents the selected text.

Syntax
object.Selection

Parameters
object - An expression that evaluates to a TextDocument object or a TextWindow object.

Remarks
The Selection property has the TextSelection type.
For the TextDocument object, the Selection property gets the object representing the text selected in a document's active view or in the topmost view if no views are active.
For the TextWindow object, the Selection property gets the object representing the text selected in the text window.

3. check the MSDN: Visual Tools and Languages -> Visual Studio 6.0 Documentation -> Visual C++ Documentation -> Using Visual C++ -> Visual C++ User's Guide -> Automating Tasks in Visual Studio. there's the description of VisualStudio object model.

4. AFX_MANAGE_STATE must be called at the beginning of every exported method in MFC dlls to correctly set the module state. find more details in MSDN

5. call Name or FullName property on pActiveDoc object
