I guess I didn't explain my problem as clearly as I had thought. I need to adjust the volume of the stream, not the device. For example, if two media are playing simultaneously, and they differ vastly in volume, how can 1 stream be adjusted such that the output is roughly the same?
any ideas?

}
from the last AfxMessageBox(s) function I get the result of "0",But from the earlier AfxMessageBox(s) function I can get the value of endpt.Why can not I get the endpt's value? If I set endpt=(CCyUSBEndPoint*)m_ComBox1.GetItemDataPtr(0); I can get the value of endpt as before? Is there any error with SetItemDataPtr(**) or GetItemDataPtr(*)?
Thank you!

Hi
Check whether you have Sort style (CBS_SORT) set for combobox. May be you forget it to uncheck. If you need in any case sorting instead of passing m_ComBox1.GetCount()-1 to SetItemDataPtr method use the value returned in a call to m_ComBox1.AddString(s); If you have sorting enabled string added is not necessarily the last one to which you try to set endpt

Friends,
I need to develop a client side application in VC++ that has to communicate with some web-service.
I never did such work before. So can you guide me how to communicate with web service in unmanaged C++. Do i need to take winsock approach ?

Using OnOK() will be not right method, i think you better use Custom Window Messages!!!
keep smilling.....b'coz smile is the shortest distance between people....

Hello
I am working with a MDI application in VC++. I have to pass command line arguments to my program. The arguments will be specified as comma seperated text for ex: test.log,test.xml. If these two arguments are passed then I should disable the maximize & minimize buttons,disable the File Menu option of the MainFrame window and also disable the first toolbar button on the MDI Child window. If none of these arguments are passed then the application should work as a normal MDI application.
I need information on two items:
1) How do I pass and process the command line information. I tried overriding ParseParam function of CCommandLineInfo class to change the default parsing ,but could not succeed in doing so. I never worked with this class before.
2)My main window has File & Window menu items. I need to disable them. My child window has a tool bar with two buttons. I need to disable only a the first toolbar button.
Can any one please give me some suggestions or information for implementing the above mentioned items in my project.
Your expert guidance can be of great help to me.
Thanks
Madhavi.
Thanks

Hi Alok
Thanks for the suggestion. Can you please give me some links to samples that have used this API. Can I ovveride the default behaviour of ParseParam() using this API. I do not wnat MFC to parse the command line information anymore. I want to do it myself.
Thanks
Madhavi.

For remote connections, i think you need to add your remote ip to the mysql database table (dont exactly remember which one... check the manual). If it worked for localhost, it should also work for remote host after you have the permission for the remote ip. Hope this helps.

How to keep the indentation when posting code? I use a
tag around the code and it looks fine in the preview but when I view actual thread the indentation is gone. Is it a tab vs. space thing or perhaps a Firefox thing?
<pre>
this (0 spaces)
should (2 spaces)
be (4 spaces)
indented (6 spaces)

It happens with Firefox (don't know if it's a Firefox problem).
Use for explicit indentations

Not with FF. CP is optimized for IE, FF seconds. Maybe you post in the 'Suggestions' forum?

else
{
int i,j,k,l;
j=k=1;
for(i=2;i<=n;i++)
{
l=j;
j+=k;
k=l;
}
//if there has the return statement,the result "2" will be absent!
//return j;
}
}
void main()
{
int n,i;
cout<<"Compute fibonacci number，pelease input the index："<<endl;
