How to create conference in iaxclient.dll???

Technically, there is no assertion on that line. If either pState or m_pmapSocketHandle were NULL, you'd get an access violation or a null pointer exception. You may have to go into the IsEmpty() method to find the line that actually asserted.

Hello all,

I have checked all the iaxclient.dll document, but i am not getting any function which can create a conference.
My problem is i want to make a call, than after holding 1st call, i have to make second call. Here i am able to hold 1st call by
int iaxc_quelch (int callNo, int MOH) function and able to make another call, But Now i want to combine both port so that all three of us can talk. so for that i am looking function but not getting anything.
So can anyone suggest me how to create conference????

Open random file inside a folder using Visual C++ 6.0 [solved]

I have a folder and I determine name of the folder.
Inside this folder, I put some text file with random name file.
How is the way I access a text file inside that folder?

There is a filelistbox in visual Basic. Is there any equivalent function in Visual C++ 6.0? so that, I can list text file inside that folder and access it.

Please help me to solve this problem.

Thank you before....

thanks Naveen for your answer.

I already tried that function, but those fuctions needs name of file as input function.
But actually the case is I don't know exactly name of files inside the folder.

Do you know any other solutions?

Thanks before,

The file name can include wild char. And in your case since you need only text file, you can pass the file name as "*.txt". This will cause the function to return only the files with extension ".txt" under that folder.

Just try with the below logic to parse even the directory inside directory for search Smile | :)

CStringArray m_FileList;

void SearchFile( LPCTSTR lpszFolder )
{
	CFileFind ff;
	CString csFolder = lpszFolder;
	if( _T( '\\' ) != csFolder[csFolder.GetLength()-1])
    {
		csFolder += _T( "\\*.*" );
    }
	BOOL bWorking = ff.FindFile(csFolder  ); 
	while(bWorking)
    {
		bWorking = ff.FindNextFile();
		CString csTemp = ff.GetFilePath();
		if(!ff.IsDots() && ff.IsDirectory())
        {
			SearchFile( ff.GetFilePath() );
		}
        if(!ff.IsDirectory())
        {
            CString csName = ff.GetFilePath();
            if( -1 != csName.Find( _T( ".txt" ), 0 ))
            {
				m_FileList.Add( csName );
            }
        }
	}
}

Are you talking about sending the LB_DIR message to a listbox?

Hello,

Is there a way to hide applicaiton menu at runtime? I would like to hide the menu once everything is loaded and once the application starts running. The application is written in vc++ 6.0 and the window is created using CreateWindowEx, I tried different dlg_styles options to hide it, but it still shows the menu.

Any suggestions??

thanks,

PKNT

I don't find any direct function support from windows programming. We may use MENUINFO Structure for change style( ex, MNS_AUTODISMISS, mask MIM_BACKGROUND).

Hi,

I wrote a program using VC++ that should scan for available wireless networks in the area.

In my SW I use the commands OID_802_11_BSSID_LIST_SCAN and OID_802_11_BSSID_LIST.

My questions are:
1. How can I Force the Wireless NIC to do ACTIVE SCAN ?

2. According to tests that I did, the card does not flush the list between scans, i.e. I get for several scan a results of an AP that was on air during an old scan, but is no longer there and new scans return's it's data as if it is still there.

I am using Intel PRO 2200BG Wireless NIC, with driver version 8.1.0.28 (dated 24/8/2004).

Relevant information That I used is here:

Some relevant info from the above link:
---------------------------------------
"
The device must do the following when performing an explicit scan in response to a setting of OID_802_11_BSSID_LIST_SCAN:

* The device must flush the current contents of its cached BSSID scan list before initiating the explicit scan request.
* The device must scan both infrastructure and ad hoc networks, regardless of the current setting of its network mode.
* The device can use either the active or passive scanning methods, or a combination of both scanning methods.

Note Active scanning is preferred whenever appropriate.
* When performing an active scan, the device sets the BSSID to the broadcast MAC address in the 802.11 probe request that it sends. The device also sets the SSID to the zero-length broadcast SSID in the probe request.
* The device must perform the scan across all the frequency channels and bands that it supports.
* The miniport driver must minimize its response time for this OID. It is recommended that the driver just initiate the scan and return NDIS_STATUS_SUCCESS in response to the setting of OID_802_11_BSSID_LIST_SCAN. The driver must not return NDIS_STATUS_PENDING or wait for the scan to complete before returning NDIS_STATUS_SUCCESS.
"

Any help will be appreciated.

You could use sscanf, or strtok or std::istringstream (or somthing like that, I always forget which one it is).

Me think the easier, but less safe and probably not well accepted today is sscanf:

int iRet = sscanf(input, "%i %i %i", &val1, &val2, &val3);

or maybe

std::istringstream buffer(input);
int val1, val2, val3; 
buffer >> val1 >> val2 >> val3;

and in general, to convert a string to a int, we can use atoi ( or atol)

This signature was proudly tested on animals.
