I have a class A in a dialog application.
A thread X is running in this class. However, i would like to update a member var in class A.
In order to have access to this member var from thread X, i did a static cast like CClassA * pClassA = static_cast<cclassa*>

I know that the above is wrong but, how can i do this?

Correct.

pass address of instance of class A to thread X parameter.

So it would look like:
CClassA pClassA = static_cast<cclassa*>(pClassA);

CListCtrl subitem image transparency?

Cpt Rick12-Apr-06 5:04

For some reason, images I insert into a list control (whether main item or subitem), always seem to have a white background, and if I change the row color for example, it looks a bit hokey, same with when they are highlighted.

I'm using a transparent image list for the images, which work fine everywhere else where transparency is required, like buttons, etc.

Anybody know any way around this behavior, other than owner draw?

Thanx,

Rick

When you create the CImageList used to store the various icons for the CListCtrl you need to setup a mask for it at the same time, check the documentation for CImageList:Create[^] for more details.

It's already masked. It just seems the list control is painting the background in the color it likes, otherwise I would see bright green.

Code for the image list looks like this:

<br />
	m_ImageList.Create(16, 17, ILC_COLOR32 | ILC_MASK, 1, 20);<br />
	m_ImageListBmp.LoadBitmap(IDB_LISTIMAGES);<br />
	m_ImageList.Add(&m_ImageListBmp, BRGREEN);<br />

BRGREEN is the color I use for transparency.

Hi aaaan,
Hope I understood your question
I think it's possible example you can run one Application
and use FindWindow Now and you can insert item to menu(example)
Infact I check this question now and get this answer

Thread-socket problem

I should send some data to two different places, right now I send all the data to one location through a socket and I need to create another socket to send some other data to a second location as follow:

If (data1){
send to LOC1;
}else
send to LOC2;

This LOC1 connection should always be open, at this point I have the socket and connection to LOC2

Please help me to know how to make the second connection to LOC1, for the first connection to LOC2 the code uses CfgRemoteAddr=127.0.0.1 and some local port: local 1222 and remote 1223.
as follow:
if( hCfg->CfgApiSocket->CfgTCP )
.
...
...
if( !hSocket->sSend( hCfg->CfgApiSocket->CfgRemoteAddr, 0, ( LPSTR )XMLString, XMLSize ))
{
//Socket::sSend( LPSTR Address, INT PortId, LPSTR txBuff, INT txBuffSize )
tmpVar = 0;
memset( Buff, '\0', MAX_LOADSTRING );
tmpVar = hSocket->GetError(( LPSTR )Buff );
LogError( "WEAPIClass", "InSockProcess", "Error sSend Socket: %d, %s", tmpVar, Buff );
LinkStatus( IPC_LINK_DOWN, 0, NULL, 0 );
}
else
{

LogAppDiag( LOGGER_INBOUND_DIAG, XMLString, XMLSize, LOG_FORMAT_ASCII );
}
what Do I need to write to get the second connection?

Appreciate any idea

Hello All

How to know the Path where the Application EXE is present in run time?

If multiple copies of the EXE is present in diff directories I have to do some process depeneding on from where it is getting executed.

I tried to search in CWinApp but i could get only the Application Name (m_pszAppName). how to find the whole path of EXE file?

Thanks for your time
Ravi

Use GetModuleFileName(NULL, ...).

You'll need to search for Access Control Entry (ACE) and Access Control List (ACL).

Well if it contains only few files keep it opened , or else go for ACL
and look for the api
1.LockFileEx or
2.SetsecurityFIle (ACL)

hi,

Does LockFileEx works for a folder also?
I could not find the Api SetsecurityFile in the MSDN.

Which file, which compiler error ?
That was a really fully detailed question.
