no, you need to use a CRichEditCtrl.

You need to handle a little more than OnPaint, but not much.

Have a look at

theres plenty of examples there of what you can do.

I'd like to have a application that is both server and client,
if the application starts, it checks if another instance of this
application is running on another server on the same LAN, if so
it should send back some indification message.

So I suppose I've to send a udb-broadcast with the server-part of
the application, the other instance receives this braodcast with
it's own server part and send's back a message to the other instance
with the client part.

Maybe someone can give a link to a source code sample Confused | :confused:

Thank you

Exchanging rows in CListCtrl

Hello !

I want to exchange 2 rows of data between them in a CListCtrl

What is the simplest and fastest way to do this ?

thank you

To exchange items 3 and 4, simply get item 3's attributes (e.g., subitem values, pointer data), remove item 3 (which would make item 4 the new item 3) and add it back as item 4. Make sense?

DXSDK 9 (Summer2004) and Visual C++ 6 issue

Hi all ... I've just downloaded the updated DirectX 9 SDK and now I cant compile the samples (capturesound) with my Visual C++ 6. I have the Platform SDK 2003 Feb installed and the problem is, it askes for UNICODE build. If i define UNICODE in the project settings, it gives another error: "__noop not defined". From MSDN, I found out __noop is a microsoft specific C++ intrinsic and my guess is, its not implemented in VC6 compiler. Is there any workaround to this problem for Visual C++ 6? Thanks in advance.

Hello,

From the DirectX9 readme:
Compiler Support
Developing C++ applications with the DirectX 9.0 Summer Update requires Visual Studio .NET 2002 or later. Visual Studio version 6 is no longer supported. Developing managed applications with the DirectX 9.0 Summer Update requires Visual Studio .NET 2003 and .NET Runtime 1.1. Developing 64-bit applications requires the Microsoft Platform SDK. All DirectX SDK supported 64-bit samples have a corresponding sample_makefile.x64. These makefiles are compatible with AMD64 and Intel64.

You should use the DirectX 8 sdk for development with VC++ 6.

Thanks for the quick reply... but the old dx9 sdk supported vc6 ... and the old code also compiles great with vc6 ... its just the samples... well... i'll try using the old sdk samples with the new sdk... Sigh | :sigh:

Not that I can think of right away. Couldn't you redefine the macros which uses __noop yourself? It's a dirty hack, but it should work, which is the main objective, right?

Destructo rin DLL

Hello

I wrote an DLL with many Code.
My Calling Programm uses

CTCPHufKommDLLApp *m_pClient;
in the .h flie
and
this->m_pClient = new CTCPHufKommDLLApp((CWnd*) this);
in the Init Dialog of the calling Window.

this i no problem.
But in the OK Button code the line
void CHUFClientDlg::OnBnClickedOk()
{
if ( this->m_pClient != NULL )
{
delete( this->m_pClient );
this->m_pClient = NULL;
}
OnOK();
}

the delete line don't work. I never come in the destruktor. But I get an Compilerhalt at
afxtls.cpp
inline void* CThreadSlotData::GetThreadValue(int nSlot)
{
EnterCriticalSection(&m_sect);
ASSERT(nSlot != 0 && nSlot < m_nMax);
ASSERT(m_pSlotData != NULL);
ASSERT(m_pSlotData[nSlot].dwFlags & SLOT_USED);
ASSERT(m_tlsIndex != (DWORD)-1);
if( nSlot <= 0 || nSlot >= m_nMax ) // check for retail builds.
{
LeaveCriticalSection(&m_sect);
return NULL;
}

CThreadData* pData = (CThreadData*)TlsGetValue(m_tlsIndex);
if (pData == NULL || nSlot >= pData->nCount)
{
LeaveCriticalSection(&m_sect);
!!!Here it stops!!!
return NULL;
!!! HERE it stops!!!
}
void* pRetVal = pData->pData[nSlot];
LeaveCriticalSection(&m_sect);
return pRetVal;
}

I can continue without more errors, but never come into destructor.
So I get a memory leak.

Who can help me?
I'm just a beginner in DLL Programming.

Thank You for every Tip.

Greetings

Hard to help from what you've written, but what did you derive CTCPHufKommDLLApp from? Was it CWinApp? Because you may only have one instance of a CWinApp derived class in an MFC program.

Gradient Masks

3-Sep-04 22:10

I'm writing my own text ticker/scroller type thing that only needs the handle to a static control on a dialog or wherever, and the rest is completely self contained in the class, the timers dont need windows to process their events. Anyway I want to have the left and right edges of the scroller fade. So say the background was dark blue, and the text was white. The white text would fade to blue at the edges. Now from my photoshop experience, at first I thought, black-to-white gradient as a mask. But how would I accomplish that with the GDI? At first I thought alpha-blending, but I didnt see a way to use a grayscale gradient as the guide for transparency. So then I saw the MaskBlt function. So I'm thinking create a monochrome memory bitmap with gradients on either side, then use that as the mask and a color memory bitmap with the text as the source, and the destination would be the solid background color layer. Then I would BitBlt that to the static control. So my question is, would this theoretically work? Am I going in the right direction?

Change filename case

3-Sep-04 20:39

What changes do I have to make to the following code inorder to use the shell to change the case of selected file(s)???

//SHFILEOPSTRUCT shFileOp;
// initialize shell file structure
shFileOp.fFlags = FOF_ALLOWUNDO;
shFileOp.wFunc = FO_RENAME;

shFileOp.lpszProgressTitle = "Test";
shFileOp.fAnyOperationsAborted = FALSE;

shFileOp.pFrom = csFile;
shFileOp.pTo = csFile1.makeLower();

shFileOp.hwnd = NULL; // Use desktop

SHFileOperation(&shFileOp);

Would this function not be working correctly because I haven't double null terminated the pFrom and pTo???

Why wouldn't it it cause an exception I wonder??? Confused | :confused:

Anyways...there are window handles so I assign NULL...any progress dialog should now use the desktop correct???

BTW - this is in ATL, so i'm not actually using CString, but i'm considering using[^]

I don't want to use any pre-made classes either, i'd like to figure out what goign wrong and do it myself...

Thanks Smile | :)

Why not test the function first to see if it will indeed do what you require. For example:

shFileOp.pFrom = "c:\\SomeFolder\\ThisFileHasMixedCase.tXt";
shFileOp.pTo   = "c:\\SomeFolder\\thisfilehasmixedcase.txt";

Friends,
I got a data grid control. The query i executed returned six fields. So when i give my recordset object to "datagrid" control, it shows six fields. I only want to show my desired fields in "datagrid" and not "all" those that are present in the recordset. How can i do so ?
