The serial I/O code should be placed in a separate thread. This allows the main thread (the one that owns the UI) to remain responsive. By putting the Serial I/O code in the same thread as the UI, painting-related problems are to be expected.

You've found a limitation of list view controls. You might want to try a CListBox instead, which allows items to be of variable height (set the LBS_OWNERDRAWVARIABLE style).

Create an own User Right in Windows XP

Hi all,

I always thought that it is possible to create own user rights in Windows XP like the ones you see in the "Local security settings" but I couldn't find anything about it.

Is this just impossible? Or how can it be done?

Thanks for any help,

Jens

Without the WS_SYSMENU and WS_CAPTION styles, I'm not sure it would still be considered an SDI application. The WS_SYSMENU style can easily be removed in the frame's PreCreateWindow() method.

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
    cs.style &= ~WS_SYSMENU;
 
    return CFrameWnd::PreCreateWindow(cs);
}

Java control in Windows app?

I have been asked to see if I can use a Java control from within an MFC app. I don't know enough Java to know if this is possible. The control I am trying to hook in is the thinkmap control (http://www.thinkmap.com[^])

Does anyone have any idea of whether this is possible, and if so, how I would go about doing it?

You can port Java code to C++ if that's what you mean.
I think it's called JRI but I'm not sure.

I have no experience myself though.

Hope it helps!

Well the first thing is this, no Java can execute without a JVM context for it to execute in. Therefore you are not going to be able to just "use" a Java component in a Win32 application since there is no JVM context. After that there is a multitude of possibilities.

Enyway thanks, Bikram Singh. Maybe you or somebody else know how to solve my problem with pdf document?

Good luck!

Norton antivirus's corporate version automatically discovers all the clients when installed on the server and THEN AUTOMATICALLY INSTALLS A client version of antivirus on the remote system
How does it do that ?

All the users and their IP address can be found out i guess , but how can it install on the remote machine ?

After using the abysmal Sophos antivirus software, which employs a similar technique, I would guess that each machine will have a small client already installed. This client will download any new updates, and install them itself.

My guess is with RPC.

Remote Task Manager works in a similar fashion. When connecting to a remote machine, if it detects that the remote machine does not have the RTM service installed and running, it will install and start the service, and then connect. It is very seamless.

recording with mcisendstring

I've got an mp3/wav player working quite well, but when i use the application to record and then play the file back, the time (length) is wrong. The file saves/plays fine.

mciSendString("open new type waveaudio alias current wait", 0, 0, 0);

mciSendString("set current format tag pcm bitspersample 16 channels 1 samplespersec 44100 wait", 0, 0, 0);

mciSendString("record current from 0 overwrite", 0, 0, 0);
.
.
.
if(m_saveFile.DoModal() == IDOK)
{
CString saveFile = "save current "+ m_saveFile.GetPathName() + " wait";
mciSendString(saveFile, 0, 0, 0);
mciSendString("close current wait", 0, 0, 0);

when i open the file and query the time format it returns "milliseconds", but the time it gives me (querying length) is usually about ten times what it actually is. The application gives the correct length of pre-saved files.....

ring any bells?

use releasedcapture, getpos() of the slider, then play from that position. need to be sure of your current time format in relation to the slider values.

this isnt an actual block of code as such, just bits pasted together to illustrate the point....

void CSPlayerDlg::OnReleasedcapturePosSlider(NMHDR* pNMHDR, LRESULT* pResult)
{
nextPos = m_position.GetPos()

mciSendString("play current from 0 notify",0 ,0, this->GetSafeHwnd());
}

you'd want to play from m_position.GetPos(), not from zero, you'll have to format the string appropriately....

you also want to set the slider range to the length of the file your playing.

Hi Friends,

I've Problem exporting a Modal Dialog from a Regular MFC DLL (Shared Library). But on runtime i'm getting error when i call the DoModal on the DLL side. This is happening for both MFC DLL Depended Host Application as well as the Win32 Host Application Confused | :confused:

.

The Code is like this

//on the DLL Side
extern "C" void __declspec(dllexport) TestFunction();

void TestFunction()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
CMyDialog dlg;
dlg.DoModal();
}

//On the Caller Side
extern "C" void __declspec(dllimport) TestFunction();

void CMyTestApp::OnAppAbout()
{
TestFunction();
}

Please Help Me... Big Grin | :-D

!

Kind regards,
Subbi.

Madame,With all due Respect,

Basiclly i never head of exporting class from MFC Regular DLL.
i think only MFC Extention DLL provide support for exporting class.

in my opinion,You create a MFCExtention DLL and then try to export Model Dilg class.
don't remeber to precede the DLg className with AFX_EXT_CLASS macro,then only you able to export it
