There is no problem with my flags actually, it is my error during copy&paste.(Sorry)
and also could not recognize the code tag(Sorry again).
I have corrected my flags by modifying my post and also mentioned the project that mine is based on(http://www.codeproject.com/dll/rsLoadtimeDLL.asp).
This example works properly.I added another class to win32dll project and used its methods from win32app project. Project properties of Load Time dll Sample and mine are the same.
Can it be about my #include header directives?
Thanx...

If you don't post the right code, it is impossible for us to help you. Did you export the functions from you class as I said in my previous post ? Or was that part also a typo ?

No, if the include directive was wrong, then you'll get a compile error, not a link error. The problem here is that the function is not found in the library.

open/save allows you to change the directory. Can you be a little more specific.
|
|
|
|
|
I guess his question is SHBrowseForFolder becuase he said a dialog for select directory .

Hello!
Which tool can I use under win32 to see which symbols are linked in the to the libray someLib.lib. I can use "nm" utility under Linux (example: someLib.a). Is there some simmilar tool for MSVC constructed libraries? I use MSVC++ .NET 2003.

Try using depends.exe, not sure if will look at a .lib file though, I know it works for .dlls

Thank you for response waldermort and benjymous. I tried both tools and it looks like it's the same tool. One comes with .NET installation and another can be downloaded from net. Both were unsuccessful in my case. They work when I open some DLL but when I open LIB file, I get "Error: At least one file was not a 32-bit or 64-bit Windows module." Is there some other tool I can use?

Rostfrei

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..
|

thank`s for u r support..issuse is closed..i have done..with the commtimeout....

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[^]
