Depends.exe and other dependency walking tools will only show the imports and exports in a DLL or EXE; I don't believe this is what you're after. I think the tool you need is Dumpbin[^] which comes with Visual Studio. Using this you can examine the symbols and contents of LIB and OBJ files.

That is exactly what I needed.
For anybody else: for Dumpbin to work you need to put "C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin" to the PATH and also "C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\IDE" because Dumpbin needs mspdb71.dll to work.
Thank you Stephen!

hi i am working on serial port communication,i have opened the port using CreateFile function ,wrote the data using WriteFile function,and Read data using ReadFile Function.Every thing is fine until here,Say for Example..the instrument is switched off..but connected to the port..how do detect whether the instrument is switched ON or OFF...?
thanks in before

You should check the documentation of your instrument. Maybe when switched ON, there is one line that is set to high (I think it is the DTR - Data Terminal Ready). If this is the case, just check for the status of this line. Otherwise you can always send something to which the instrument is supposed to respond. If you don't get an answer, then the device is either not connected, either switched OFF. I don't think it is possible to make a difference between disconnected and switched off.

how to check DTR..is there any API fucntion for it..?
|
|
|
|
|
I think you can use GetCommModemStatus[^]. I think I was wrong, you have to check for the DSR (Data Set Ready) line, not the DSR (I always mix them).
|
|
|
|
|
Is there any other alternative..?..i have tried used GetCommModemStatus function..its returning false..even if..the instrument is switched on..
|
|
|
|
|
Did you pass the correct handle ? After the port has been opened ?

Yes, as I said previously: send something to which your device is supposed to answer. If you don't receive an answer, then the device is not connected or switched off.

yeah i have sent..correct handle..i have opened port it in OVERLAPPED MODE..i am using WaitForSingleObject function..when i write data ..its able to write..when i start reading the data..it is getting stucked..at WaitForSingleObject function..

As Cedric Moonen already said, you can check the DSR signal.
In addition you should raise the RTS (Request To Send) signal and check for the reply from the device, CTS (Clear To Send). If you get a transition from Off to On in the CTS line, you can be pretty sure the device is powered on.
For the serial communication, i suggest you use a serial commuinications library, the are some good ones here at CP.

Hello.
The problem with detecting serial devices is that the serial port very often can have a random status when the serial port is unconnected.
I.e. the DSR signal can be in it's "On"-position even when the serial port isn't even connected! (It depends on the hardware).
The only reliable way of detecting if:
1.
There *is* a device conncted.
2.
The device is powered on.
is to catch a transition on one (or more) status lines. An easy way is to ask the device if the PC (Data Terminal) may send data to the DS (Data Set).
If the DS raises it's Clear To Send signal, then the PC(DT) may send data to it.
Check out MSDN for the documentation, http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devio/base/dcb_str.asp[^]

By 'free' do you mean "other peoples hard work so I can be lazy"? or free as in "I don't want to pay even the the author would like a small donation"?
|

|

Just tell me where, pay or free library. I'll consider that I should pay or not later.

Why don't you ask someone who knows? This is the Visual C++ / MFC discussion board, in case you haven't noticed.

Hello
Can anyone give me a little short description of the different shortings in visual C++,
And maby give me an example of what they are?
ATL, CLR, GENERAL, SMART DEVICE, WIN 32 APPLICATION..
Thanks for answer
Regards
|
|
|
|
|
shortings ?
Where did this list come from ?
ATL is the Active Template Library, for COM
CLR is the .NET framework, C++/CLI apps
When the General talks, you better listen to him
A smart device is a device that is smart, such as a scientific calculator, or a handheld windows device.
Win32 is what all our apps really are, a Win32 app would be an app that doesn't use the CLR, or MFC, it uses the Win32 API directly.
