Sure, I'd like to read your articles, but I don't know much about C#, is it the same with C++? Where can I find them?
Thanks

XOR the watermark image onto the primary image. then save with a lossless algorithm (ex. not JPG).

Hi,
I am new to VC++ win32...I was trying to compile and run a project..it has
#include <newdev.h>
#include <cfgmgr32.h>
in one the cpp files...
cfgmgr32.h file has #include <cfg.h>
But when compiling the project it says that it could'nt find these files.
I understand that the newdev.h and cfg.h are api files that comes with .NET SDK package. But I could'nt find those files in sdk directory..

What should I do or how should I get those files..
Thanks in advance..

m_ClientFileListBox.ResetContent();
m_ClientFileListBox.Dir(DDL_READWRITE, Path);

how do i load files of just *.txt and *.csv only?

thanks,

Change the pattern from *.* to *.txt and *.csv respectively.

does that require two lines of code?

Is it possible to do it all on one line?

or do i have to call m_ClientFileListBox.Dir(DDL_READWRITE, Path) two times switching the file types in the Path variable?

If you are just searching a small number of folders, the Dir() method can be called once for each different pattern. This will obviously not work when a large number of folders are involved. In that case, specify *.* as the pattern and filter out each file as it is encountered.

Destroying modeless dialog containing child modeless dialogs

Maximilien8-Mar-05 9:09

8-Mar-05 9:09

( following a question I asked yesterday ... )

I have a modeless dialog that contains a series of child modeless dialogs ( to implement basic UI components ).

When I destroy my parent modeless dialog, I call

void MyParentDialog::KillMe()
{
  DestroyWindow(); /// will eventually call PostNcDestroy and I will delete this.
}

Is it necessary ( or preferred ) to call DestroyWindow ( or something else ) on each child modeless dialog ?

for example :

void MyParentDialog::KillMe()
{
  m_pChild1->DestroyWindow();
  m_pChild2->DestroyWindow();
  m_pChild3->DestroyWindow();
  ... 
  DestroyWindow(); /// will eventually call PostNcDestroy and I will delete this.
}

Thanks again.

Max.

No, they will be destroyed automatically. In fact, they will be destroyed before the parent window is destroyed.

I need to parse and generate XML documents, do you have any tip on a good performance library for that ?
The development platform are Visual C++ 6.0 and Visual Basic 6.0 (no .NET).

Thanks for any help !

Compiling a multithreaded program

MALDATA8-Mar-05 6:41

8-Mar-05 6:41

There's some sample code on MSDN that I can't get to compile. It says that there's a problem with the KbdFunc line:

_beginthread( BounceProc, 0, &ThreadNr );

specifically, error C2664: '_beginthread' : cannot convert parameter 1 from 'void (char *)' to 'void (__cdecl *)(void *)' None of the functions with this name in scope match the target type

Any idea why? All I did was paste the code into an empty project and set the runtime library to /MTd. Please let me know what I need to do to fix it and what that error actually means.

I'm using Visual Studio .NET 2002.

Thanks!

IIRC Visual Studio 7.0 (2002) was the first version to set the /TP switch in the compiler options by default. This tells the compiler to compile code as C++ regardless of the file extension.

One of the few incompatibilities between C and C++ is that in C, you can implicitly convert from a void* to any other pointer type. C++ requires a cast. The sample code suggests a filename of bounce.c, which would cause the compiler to compile the code as C if the /TP switch is not supplied.

To fix this, change the declaration of BounceProc to

void BounceProc( void *pvParam )

and add a declaration at the top of the function body:

char* MyID = (char*) pvParam;

If you still get errors, for example referencing __stdcall, you should explicitly add __cdecl to the BounceProc declaration.

Hi everyone
What I have is a vb program that I am converting to visual C++
iv done most of the convert but am having a problem with this one. All I want to do is when my VC++ program runs that it show the current
Month Day Year in seperate boxes here is the vb code.

Public Sub today()

'Get today's date from system

Dim currentdate, tempDay, tempMonth, tempYear As String
Dim tempDate As String
Dim location, StrLen As Integer
Dim convert_month As String

tempDate = Date$
tempMonth = Month(CDate(tempDate))
tempDay = Day(CDate(tempDate))
tempYear = Year(CDate(tempDate))
currentdate = tempMonth & "/" & tempDay & "/" & tempYear

StrLen = Len(currentdate)
location = InStr(currentdate, "/")
txtMonth.Text = Left(currentdate, location - 1)
convert_month = Convert_Date_Int2Str(txtMonth.Text)
txtMonth.Text = convert_month
currentdate = Right(currentdate, StrLen - location)
location = InStr(currentdate, "/")
txtDay.Text = Left(currentdate, location - 1)
currentdate = Right(currentdate, 2)
If (CInt(currentdate) < 90) Then
txtyear.Text = "20" & currentdate
Else
txtyear.Text = "19" & currentdate
End If

If I understand this correctly, you just want to grab the current time and display it in edit boxes.

To display the entire date in a single box:

(editcontrolstring is the CString variable associated with the edit box.)

CTime tDate = CTime::GetCurrentTime();<br />
CString strDate = tDate.Format( "%B %d, %Y" );//This will give you month day, year<br />
editcontrolstring = strDate;

Now, to break it down a little more, you can do something like this:

CTime tDate = CTime::GetCurrentTime();<br />
CString strDate = tDate.Format( "%B" );//This gives the month<br />
editcontrolmonthstring = strDate;<br />
strDate = tDate.Format( "%d" );//This gives the day<br />
editcontroldaystring = strDate;

And so on.

hiding a dialog?

hiho@ll

i'm trying to hide a dialog through command line
i'm using the void OnShowWindow(BOOL bShow,UINT nStatus); event

void OnShowWindow(BOOL bShow,UINT nStatus){
if(hide)
bShow=false;
CDialog::OnShowWindow(bShow,nStatus);
}

what i want:

if the command line says the dialog should not be displayed

i set a bool variable hide=true

and (i think) every time the dialog should be displayed the OnShowWindow function is called!?

my OnShowWindow gets called one time
i set the bShow to false
and then the window is displayed

is there another event which displays the dialog window?

thx
