"2" is not a number but a C-Style null terminated string (actually, an array of two chars : { '2', '\0' }.
idineen wrote: how can i stop this number from being converted to its ascii value of 50 when passing it through the parameter.
can you show us a piece of the code by which you call the function, and how the function uses this parameter too ??
i'm quite sure you don't use it properly.

the code below is used to put a snmp object id into a pdu packet along with 3 parameters. the third parameter is used by the program to identify that the paramter is interrupted as a integer. the 4th parameter "test" is the number that i want to pass, this parameter is of type "(u_char *)" and the last is the length of the string.
snmp_pdu_add_variable(pdu, oid, oid_length, ASN_INTEGER , test, strlen(test));//
thanks

Hi Idineen:
Do you have access to the source code of snmp_pdu_add_variable?
It could be that all variables are passed in as u_char*, then because of ASN_INTEGER, that function has code to convert it to an integer from the string value in test.
|
|
|
|
|
Try this:
int test = 2;
snmp_pdu_add_variable(pdu, oid, oid_length, ASN_INTEGER, reinterpret_cast<u_char*>(&test), sizeof(test));

> Should i set async read/close on the newly created socket?
The newly created socket will inherit the event mask from the server socket. It depends on the implementation of the async socket class that you use, set the events you are interested in the server socket instance and from there you create more sockets in your 'accept' handler (which will then use the same event mask).
Do not try to read data in the 'accept' handler. Have a 'read' handler which will tell you when there is (more) data available.

Hi sudeep_br
Name.GetWindowText(for read from Name)
Location.SetWindowText(write to Lication)
// like this
CEdit m_Edit1,m_Edit2;
CString Str,str="c:\\Desktop Search\\";

Hi sudeep_br,
This is a sample,I hope that help you
CEdit m_Edit1,m_Edit2;
CString m_Test1;
CString m_Test2;
m_Edit1.Create(WS_CHILD|WS_VISIBLE,CRect(0,0,100,23),this,1);
m_Edit2.Create(WS_CHILD|WS_VISIBLE,CRect(0,50,100,23),this,1);
m_Test1="C:\\DesktopSearch\\Index\\";
m_Edit1.SetWindowText(m_Test1);//Now set this string to edit1
////////Now/////////
m_Edit1.GetWindowText(m_Test2);//Read from edit1 into m_Test2 that is CString
m_Edit2.SetWindowText(m_Test2);//Now set m_Test2 to m_Edit2
//if you test this code it's fine no problem in your code
1-objFD.BrowseFolder(hWnd,m_Enter_Location);
you assain class CEdit to this function,But this function need to CString yes?
unless m_Enter_Location is CEdit well you need to get string from this Control then assain
value to function BrowseFolder.
2-I think that problem is m_Enter_Location = szDir;
m_Enter_Location is variable control(CEdit) but szDir is TCHAR
you need to m_Enter_Location.SetWindowText(szDir);
Right?

yes because you need to caption or NULL

If you add a EN_CHANGE handler for the first control, you can then read the changed text, put it on the end of location text, and update the location edit control.
ON_EN_CHANGE is the key you are looking for, I think.

hi all,
I am using the following code to mute the speaker control.But i am not able to disable the speaker control.Can anyone please tell me how to do it.Disable in the sense that user should not be able to access the speaker control.

Sorry ,i forgot to put the code.The code is as shown below::
MMRESULT result;

result = mixerOpen(&hMixer, MIXER_OBJECTF_MIXER, 0, 0, 0);
//obtain a handle to the mixer device.
if(result!=MMSYSERR_NOERROR)
{
::MessageBox(NULL,"Mixer could not be opened","1",MB_OK);
return;
}
//we need to get the speaker line of the mixer device
MIXERLINE ml = {0};
ml.cbStruct = sizeof(MIXERLINE);
ml.dwComponentType = MIXERLINE_COMPONENTTYPE_DST_SPEAKERS;
result = mixerGetLineInfo((HMIXEROBJ) hMixer,&ml, MIXER_GETLINEINFOF_COMPONENTTYPE);
//we need to get the volume control of the speaker line.
MIXERLINECONTROLS mlc = {0};
MIXERCONTROL mc = {0};
mlc.cbStruct = sizeof(MIXERLINECONTROLS);
mlc.dwLineID = ml.dwLineID;
mlc.dwControlType = MIXERCONTROL_CONTROLTYPE_MUTE;
mlc.cControls = 1;
mlc.pamxctrl = &mc;
mlc.cbmxctrl = sizeof(MIXERCONTROL);
result = mixerGetLineControls((HMIXEROBJ)hMixer,
&mlc, MIXER_GETLINECONTROLSF_ONEBYTYPE);
//we set the mute and unmute values
MIXERCONTROLDETAILS mcd = {0};
MIXERCONTROLDETAILS_UNSIGNED mcdu = {0};
mcdu.dwValue = 65535; //0 for unmute and //65535 for mute.
mcd.cbStruct = sizeof(MIXERCONTROLDETAILS);
mcd.hwndOwner = 0;
mcd.dwControlID = mc.dwControlID;
mcd.paDetails = &mcdu;
mcd.cbDetails = sizeof(MIXERCONTROLDETAILS_UNSIGNED);
mcd.cChannels = 1;

Your comment is wrong.
So what's not working? What is the value of result?

Sorry,Mute and Unmute are working fine.I have written the following code to disable the mute control,but it is not working.
MIXERCONTROL mc = {0};
mc.fdwControl=MIXERCONTROL_CONTROLF_DISABLED;
Please Help.

if(result!=MMSYSERR_NOERROR)
{
::MessageBox(NULL,"mixerGetLineControls failed","2",MB_OK);
}
//we set the mute and unmute values
MIXERCONTROLDETAILS mcd = {0};
MIXERCONTROLDETAILS_UNSIGNED mcdu = {0};
mcdu.dwValue =lVal; //0 for unmute and //65535 for mute.
mcd.cbStruct = sizeof(MIXERCONTROLDETAILS);
mcd.hwndOwner = 0;
mcd.dwControlID =mc.dwControlID;
mcd.paDetails = &mcdu;
mcd.cbDetails = sizeof(MIXERCONTROLDETAILS_UNSIGNED);
mcd.cChannels = 1;
result = mixerSetControlDetails((HMIXEROBJ)hMixer,
&mcd, MIXER_SETCONTROLDETAILSF_VALUE);
if(result!=MMSYSERR_NOERROR)
{
::MessageBox(NULL,"mixerSetControlDetails failed","3",MB_OK);
}
The above code does not disable the MUTE control.
I have checked all the return values,all of them return MMSYSERR_NOERROR as the return value.
Kindly help me to fix this problem.

What exactly are you expecting this code to do, disable the Mute all checkbox? If so, see here.
