Hi DavidCrow,

Long back I have received many usefull replies from you regarding VC++ 6 (MFC) programming. Thanks for that.

I don't know what's wrong or great with IDE. Just started using the .Net 2003.
I just wanted the information regarding finding an easy way to search for all the hard coded strings from the source code instead of manual search or search using (").

Regards,
Neeraj

May be you have see the Process Explorer[^] from sysinternals. In that tool take the properties of an exe, there will be a tab called string. All items list in that are strings used in your application.

Thanks Naveen.

It was useful for my code investigation.
From this tool I was able to see all the strings from my application EXE.

I included windows media player control successfully, but now I am getting problem with that. I am not able to play movie inside that. It does not resond to any of its functions like SetFileName, SetEnabled,Play. Its buttons doesnot activate. All of its buttons remain inactive.
My friend has used it very well in VC++

Where are you getting these "functions" from?

I think there is another function called SetURL(). call that function instead of the SetFileName().

No, you can't redistribute it.

I am porting a COM object from VC6.0 to Visual Studo 2005 and I get the following error:

error C2011: 'spcADO::CursorTypeEnum' : 'enum' type redefinition

The reason for this is that the file msado15.tlh gets generated in the DebugU directory AND the project directory.
Any idea how I can solve this?

Thanks,
Jerome

Strange, #import doesn't generally do this. Have you tried quitting VS, removing the tlh/tli files, and doing a clean and build?

Yes it was weird - I tried that indeed but it did not work.
I think it was caused by the fact that two cpp files had the same name. For some unknown reason, the obj files were generated incorrectly. I removed them from the project and re-added and it now works. Touch wood!
Thanks for your help anyway!

Handle the NM_CUTOME draw message and put the following code inside it.

void TreeCtrlEx::OnCustomDraw( NMHDR* pNMHDR_i, LRESULT* pResult_o )
{
NMTVCUSTOMDRAW* pLVCD = reinterpret_cast<nmtvcustomdraw *="">( pNMHDR_i );
NMCUSTOMDRAW &nMcd = pLVCD->nmcd;
*pResult_o = CDRF_DODEFAULT;
switch( nMcd.dwDrawStage )
{
case CDDS_PREPAINT:
// Item prepaint notification.
*pResult_o = CDRF_NOTIFYITEMDRAW;
break;

case CDDS_ITEMPREPAINT:
{
// Set the color of the text according to its state.
HTREEITEM nRow = reinterpret_cast< HTREEITEM >( nMcd.dwItemSpec );
if( CDIS_SELECTED == ( nMcd.uItemState & CDIS_SELECTED ))
{
pLVCD->clrText = clrSelText;// Selected text color
pLVCD->clrTextBk = clrSelBk;// Selceted backgroung
}
else
{
pLVCD->clrText = clrNormal;// text color in normal state
pLVCD->clrTextBk = clrBk// bakck ground color in normal state
}
// Allow it to do the default painting.
*pResult_o = CDRF_DODEFAULT;
break;
}

default:
*pResult_o = CDRF_DODEFAULT;
break;
}

There is a compiler limit on string literals of 2048 characters, so this has nothing to do with CString.

How do you create this string in the First Place. You hardly typed it by hand!
Anyways:

Try CString MyString;
MyString.GetBuffer(32000);

The problem occurs with items such as strings which are zero terminated. If the compiler does not find a 0 after a reasonable number of chars, ( and 2048 is a reasonable limit in most cases)the compiler decides that there must be a syntax error (forgotten a terminating ") etc.

Individually i am able to communicate with either systems but facing problems when executed and trying to interact with 2 systems simultaneously. The main reason for this is the I am using a Pentium 3 processor which is a must for me.Can anyone help me out to overcome this problem in pentium 3 processor.

The correct syntax should be:
int arInt[] = {....

int nSize = sizeof(arInt) / sizeof(int);

this is this.

Then if it is a array of string.Should I write like this.

char * arLang[] = {"english", "chinese"};
int nSize = sizeof(arLang) / sizeof(char);
