I have developed an app in VC++ to cutomize the IE.
I have a console based application which can be accessed thru this IE.The console app has many function keys supported for its own functionality.
My idea is to provide Function Key support from F1..F12 in the IE so that my console app can get those function keys when invoked from IE.
Pls help ..how to achieve this..
Is it possible to do...???
Thanks in advance

Hi!
I want to develop an applcation in VC6, which detect and then plot the graph of network traffic. This graph should be avaialble to user on a web browser.
I don't know where to start except somewhere I should be using winsock.
I am Intermediate level in Win32SDK and beginner for MFC.I hate java and want to prove that better things can be accomplished using VC than that Lazy Java.
Three Cheers for this forum and VC community

yeah Buddy i am too the Vc Fan.
About your problem,you have to use iphelper api not
winsock.
there is good example of firewall by Sudhir Mangla
to get the network traffic.
about ploting the graph,from what ever i know,you
can follow this little logic or wait for other
Programmer to reply.
->if you familiar with any WebLanguage,just write
the data into the file and notify that webpage
about the data you have recieved from network to
disply it on WebBrowser

you can do this by reading the data file written by you network application at regular interval. easiest way i think.

I am working in Crystal reports 10 in vc++ 6.0.
When i click the right mouse button an the empty report viewer it causes an exception.
I tried to catch the click and oncontextmenu events of the report viewer activex control but they only work if there is a report in the viewer.
How should i handle this exception.

I am working with crystal reports 10 in vc++ 6.0 and need to create a new report. I am using the following piece of code.
#import "craxdrt.dll" no_namespace<br />
<br />
IApplicationPtr m_pApplication;<br />
IReportPtr m_pReport;
....
m_pApplication.CreateInstance("CrystalRuntime.Application");
....
Everyting goes fine till here. But as soon as i call the NewReport() method in the IApplicationPtr it throws a com exception.
m_pReport = m_pApplication->NewReport() throws a com exception.
Dont know whats going wrong.

|

I'm assuming your CreateInstance has failed. What is the HResult returned from it.
I usually create a Crystal instance using
HRESULT hr = m_Application.CreateInstance(__uuidof(Application));
What exception is thrown? Have you added an exception handler to get more details of the exception?
try<br />
{<br />
m_pReport = m_pApplication->NewReport();<br />
}<br />
catch(_com_error& e)<br />
{<br />
TRACE("COM Error: %s %s %x\n", e.ErrorMessage(), (LPCTSTR)e.Description(), e.Error());<br />
}

Dear all,
I am using Microsoft VS 6 and when I first built my program's project with the app wizard I select the English Language for "what language would you like your resources in?".
My question is: after I have built the project, can I change the language DLL? The reason is becuase my software needs to work for several languages. In fact I am running a Chinese version of Windows and all the Chinese displays on using the English DDL, EXCEPT the list control. When Chinese is displayed in it, it comes out as rubbish. This is not the case with drop-down menus and text boxes? Anyone know why this might be?
I tried building a test project with just a List Control but used the Chinese DLL and it seems to be ok. So I am wondering if I can change the DLL my program uses now that I have built my program already with the English one.
Any help would much appreciated.
Graham.

Hi all,
This is my first post in this A-real-time-code-site( The Code Project).
Before 2 months I purchased the Visual Studio.NET the acadimic version, and since that time I was trying to do some coding in Visual C++.net, VB.net and some smart phone applications. But the problem is that I don't know why so far I don't have the touch for that, I mean I have ideas but I can't deal with the .NET thing??!! putting in mind that Back in my electronic and telecomunnication school I was able to do many coding in the C++ ( Borland builder and others), But when I migrate to .NET, BANG, I don't have a clue.
Maybe it's like what MORPHUSE told NEO in ( The Matrix) " Knowing the path is not like wlaking on the path".
So please I need your advices and some tips and some really good books that you guys have worked with it.
Best Regards.

hi there,
i'm trying to make a class capable of playing wave files and returning play position and levels.
i'm using MCI functions and, for the most of it, it works ok.
for example, i get the play position using MCI_STATUS_POSITION:
DWORD CWave::GetPosition()
{
DWORD lnPos=0;
DWORD lnErr;
MCI_STATUS_PARMS loStatus;
loStatus.dwCallback=NULL;
loStatus.dwItem=MCI_STATUS_POSITION;
lnErr=mciSendCommand(m_nDeviceID, MCI_STATUS, MCI_STATUS_ITEM |MCI_STATUS_POSITION| MCI_WAIT,(DWORD) (LPMCI_STATUS_PARMS)&loStatus);
if(!lnErr)
{
lnPos=loStatus.dwReturn;
}
else
{
UINT lnErrL;
char * lsErr;
if(mciGetErrorString(lnErr,lsErr, lnErrL))
AfxMessageBox(lsErr,MB_ICONERROR);
else
AfxMessageBox("An unknown error occured",MB_ICONERROR);
}
return lnPos;
}
but i can't understand why MCI_WAVE_STATUS_LEVEL returns an error: "MMSYSTEM 322: All wave devices that can record files in this format are in use."
DWORD CWave::GetLevels()
{
DWORD lnLevels=0;
DWORD lnErr;
MCI_STATUS_PARMS loStatus;
loStatus.dwCallback=NULL;
loStatus.dwItem=MCI_WAVE_STATUS_LEVEL;
lnErr=mciSendCommand(m_nDeviceID, MCI_STATUS, MCI_STATUS_ITEM |MCI_WAVE_STATUS_LEVEL| MCI_WAIT,(DWORD) (LPMCI_STATUS_PARMS)&loStatus);
if(!lnErr)
{
lnLevels=loStatus.dwReturn;
}
else
{
DisplayErrorMsg(lnErr,"Error while getting levels");
}
return lnLevels;
}
....can anyone help???

Hi,
I have to write a program that will talk to a device through USB. In the past I have built a program that is able to talk to devices through the RS232 COM ports. In this case Windows abstracts the Serial ports as just file handles. My question is, how exactly do I get at a USB device from a Visual C++ program? Are there Win32 API functions that will do it for me?
I have found lots of information about writing Windows USB drivers and they all say it is difficult because you need to have an understanding of the Windows kernel. However I don't think this information applies to me beacuse I just basically want to send bytes down to a USB device.
Thanks in advance!

If you can, try to find a virtual serial port driver for your device which will map USB into something which will work with the WriteFile API. We used this approach for working with bluetooth USB dongles on our last project and it worked quite well.
If you can keep you head when all about you
Are losing theirs and blaming it on you;
If you can dream - and not make dreams your master;
If you can think - and not make thoughts your aim;
Yours is the Earth and everything that's in it.

Thanks for all your responses. It seems like this is the most straightforward way because I already have code that talks through RS232.
I will investigate this. But if you have any links it would be great 
Thanks!

Ok.... there wasn't a memory leak in my program.....
It turns out I was writing over the end of an array of struct (by 1). It was bad programming.
However, it did confuse the runtime into thinking there was a leak, but at least it said something.
Thanks everyone.

Hi,
Think that the leak is related to a string variable having the values at some stage as text, Batc, ..... shown within Data:<..>.

What is the most portable way to do it? I want to make it fullscreen just like IE does it: no caption bar, no borders, no task bar. Currently I'm just removing the WS_OVERLAPPEDWINDOW bits and sets window state to SW_MAXIMIZED. It does work on my Windows XP work machine without a glitch, but does not cover the task bar on another Windows XP machine. Obviously I'm doing something wrong, which just happens to work on my machine. Any ideas?

Gud Morning Sir,
i think after doing all the thing you have stated,
you can use MoveWindow() to increase the size of window
to cover the task bar.
and you can Get current Screen Resolution by using
these api's
-->int GetSystemMetrics(
int nIndex // system metric or configuration setting
);
----->BOOL SystemParametersInfo(
UINT uiAction, // system parameter to retrieve or set
UINT uiParam, // depends on action to be taken
PVOID pvParam, // depends on action to be taken
UINT fWinIni // user profile update option
);
Sorry If i wrong
