Hi,
The methods specified in the above link doesnt support in vs2005 or 08;
I think those are for VC6
So, if any body knows how to resize the property sheet in 05 or 08 let me know!
Thanks...

What's the difference between import liberary and static program liberary, they seems to have the same suffix(.lib)?
Can somebody provide me the explicit demonstration of lib file. BTW, i have learnt PE format already.

When you compile a file called, say, "A.cpp", you normally get an output file called "A.obj". Essentially a .lib file is a library that contains multiple .objfiles. Historically there was a separate command for creating them. If you've studied the PE file then you're already know most of what you after. See here[^].

And an import library contains the signatures of the exported functions and the name of the DLL file that contains the actual implementation.

why lib is smaller than dll?
if lib is the combination of all objects, and dll also a combination of all objects(some have been allocated though), dll should be equal of smaller in size than lib.
And are you saying import liberay and static program liberary are exactly the same?

lib doesn't contain any "logic" inside. It's just a dummy. It contains information about the exported symbols from the dll. How will it have the same size of the dll then? But if it's a static library, yes, it will have brains and the size will be big. Unlike a dll, this static libraries get "fixed up" to the executables. But I guess you aren't concerned about the latter.

That's not necessarily true. Import libraries just contain, essentially, function names and the name of the containing DLL, so it’s true in that case. However, the “other” sort of lib file contains machine code and data.

Did you really read my message till the end?

I think both mean the same.

It need not be. If it's an import library it will be quite small.

Dear All,
I have an application which connects to remote machine. I want to check the behavior of this application when remote machine is suddenly restarted. For this purpose, i have to physically access remote machine and restart it. After that i check how my application behaves.
By restarting the remote machine, i am actually making that remote machine inaccessible. Now i want to do it programatically so that i don't need to physically connect to remote machine to restart it.
How can i make a "remote" machine inaccessible from my local box for a certain time ? I want to do it programatically. By making remote machine "inaccessible" doesn't necessarily mean that i restart it. What i want to do is to just temporarily make it inaccessible from my local box.

Unplug the network cable on your machine.

You can use PsExec utility to restart a remote computer.
Or you can use Remote Desktop Connection Application (mstsc.exe) to connect with remote computer and Shutdown.
Restart,or if you remove the network, both will result a broken network connection.

i difine a custom message(i want to post it to a driver)
#define WM_INTERRUPT WM_USER+100
then i use it as a parameter in the function DeviceIoControl
<br />
...<br />
ULONG nBytesRead;<br />
<br />
if (! DeviceIoControl(<br />
m_hPCI9054, <br />
IOCTL_SET_NOTIFICATION_EVENT, <br />
&WM_INTERRUPT, <br />
sizeof(WM_INTERRUPT),<br />
NULL,<br />
0, <br />
<br />
&nBytesRead,<br />
NULL<br />
)<br />
...
it makes an error:
...'DeviceIoControl' : cannot convert parameter 3 from 'const int' to 'void *'
how to fix it?
i 've tried ,then i have no regret

You have defined WM_INTERRUPT as a preprocessor symbol. During compilation, the compiler is going to simply replace all occurrences of WM_INTERRUPT with the number 1124. So what you're trying to do essentially, is this - &1124 which of course, does not make sense. Depending on how you have implemented your driver you can choose to pass WM_INTERRUPT directly like so - (void *)WM_INTERRUPT. This will of course, mean that you should not be dereferencing this value from your driver.

The parameter should not be constant as per the documentation. Do as follows
LONG lData = WM_INTERRUPT;<br />
<br />
ULONG nBytesRead;<br />
<br />
if (! DeviceIoControl(<br />
m_hPCI9054, <br />
IOCTL_SET_NOTIFICATION_EVENT, <br />
&lData, <br />
sizeof(WM_INTERRUPT),<br />
NULL,<br />
0, <br />
&nBytesRead,<br />
NULL<br />
)

Hi,
Would anyone know in which of the overrideable methods can I set the Window Name ??
::SetWindowText just seems to set the Text When I do I a FindWindow for that string I dont seem to find it
|
|
|
|

What exactly do you mean by Window Name if you're not referring to its text/title?

I am converting a program I wrote in C to MFC
In C
I used CreateWindow to Create the Main Window and the Second Param
LPCTSTR lpWindowName,
Was the Window Name
I am able to Do A FindWindow on this to get the Window Handle
When I converted the Program to MFC the Wizard Creatred a bucnh of Objects
Cwnd .. (guess for the Client Are .. CFrameWnd for the Frame
I guess I was looking for Where .. Some overrideable method to insert the Window
Title
When I tried doing it durning ::OnCreate using SetWindowText the Window title Displayed but the FindWidnow
didn't get the Window Handle
Durning PreCreateWindow setting the Window name by setting lpszName memeber of CreateStruct structure
The Program bombed
I am using FindWidow in Dos App to Do IPC with the GUI PROGRAM
thankx
