since this is the Visual C++ message board and not some chat-site.
"Hello World!" would`ve been at least a little more appropriate than just plain "hi"
Other than that, when starting a new thread in this message board, please just post C++ related questions. There are message-boards for non programming related topics in the Lounge and Soapbox...

It is easy to use exported functions from dll using LoadLibrary and GetProcAddress.
however it seems that there is no way to use exported functions from exe(executable application).
In other words, how can the communication between two applications(such as, function call) be done?
thanks

I think the only way to do that is RPC (Remote Procedure Call) used for communication of application running on remote hosts. I don't think there is another way to export functions from an executable, that's the job for a dynamic library only. A more common way for communication between apps is shared memory or pipes if they are running on the same host as RPC is a bit 'expensive' on CPU considering it adds some overhead.

Hi, I 'd like to ask an MFC related question. I have an SDI application and I want to show a modal dialog just when my main frame appears on screen. Which event of my CMainFrm should I register for that? I've tried ON_WM_CREATE and ON_WM_SHOWWINDOW but the first is called before any drawing has been done and the latter doesn't get invoked at all! Could you help me plz?

When exactly do you want your dialog to appear? Just before or just after the mainframe appears on screen?

Just after the mainframe appears.
To Cool Jul: I don't think the timer is a good idea, because the initilization in a slow machine may take more time than in mine pc. Thanks though!

Here's a thought:
1) Create a user defined message, that you can post to display the dialog.
2) In the main frames OnSetFocus(), just post the message (post not send).
If there is already a command that allows the user to display the dialog then you can skip step 1 and just post that messge.

Hi,
I am using DDEML. What if I want my DDEML Server application to receive some data from a Client, process it and send back the result to client.
What I am doing so far is:
I send some data from Client to Server through XTYP_POKE transaction.
In Server's DDECallBack function, I store this data in some static variables.
Then I send an XTYP_REQUEST transaction from Client to Server, to process the data sent in XTYP_POKE transaction.
The Server application, on receiving the XTYP_REQUEST transaction, process the data received in XTYP_POKE transaction and returns the handle of result.
What I fear here is that what if the Server receives another XTYP_POKE transaction in between above XTYP_POKE and XTY_REQUEST transactions.
Means, When a client sends "A" data to Server through XTYP_POKE, an another Client sends "B" data to Server before Server could get and process the XTYP_REQUEST from first Client, the Server may generate and return wrong data.
Is this right? If yes, what I could do to prevent this? Is there a way where Client could send and receive data through XTYP_REQUEST itself?
Please help. Quick replies are appriciated.
Thanks In Advance,
Vipin.

I downloaded the mentioned project and tried to run the project but could not succeed.
Although I included all needed .lib files and header files yet I am getting two errors
1)error C2065: 'CoInitializeSecurity' : undeclared identifier
2)error C2065: 'EOAC_NONE' : undeclared identifier
However the function CoInitializeSecurity( ) is declared in "objbase.h" and I have included this file too.
So Please tell me how to remove this problem.
Please reply .
Thanks & Regards.

Hi all,
I have dll(mfc) which displays dialog with list control with some file [with path] ( .doc,.msg, ... )
When user double clicks my code opens file in maximize mode useing ShellExecuteEx. It returns me HANDLE hProcess. All works fine.
But some file like msg file are not opening in MAXIMIZE state. After looking deep into that i conclude that it is handled by MS Outlook.( means if last msg file is opend in normal window (not maximized) then my code will not open msg file maximized!!.)
So what i want is HWND from hProcess. so that i can send message to that window for maximize!!!
I have searched a lot and also applied a code. but i think my dll handles this so i m not getting required results.
//////////////////////////////////// hProcess is returned by ShellExecuteEx
WaitForInputIdle(hProcess,1000);
FILETIME lpCreationTime, lpCreationTime2;
FILETIME d1,d2,d3;
DWORD dwProcessId;
HANDLE hProc;
GetProcessTimes( hProcess, &lpCreationTime, &d1, &d2, &d3 );
HWND hTemp = ::FindWindow(NULL,NULL);
while ( hTemp != NULL )
{
if ( ::GetParent(hTemp) == NULL )
{
::GetWindowThreadProcessId(hTemp,&dwProcessId);
hProc = OpenProcess(PROCESS_QUERY_INFORMATION, 0, dwProcessId);
GetProcessTimes( hProc, &lpCreationTime2, &d1, &d2, &d3 );
CloseHandle(hProc);
if ( lpCreationTime.dwHighDateTime == lpCreationTime2.dwHighDateTime &&
lpCreationTime.dwLowDateTime == lpCreationTime2.dwLowDateTime )
{
//("Sending Message"); // Never came here
::PostMessage(hTemp,WM_SYSCOMMAND,SC_MAXIMIZE,0);
break;
}
}
hTemp = ::GetWindow(hTemp, GW_HWNDNEXT) ;
//"looping");
}
// i have also tried with EnumWindows and its proc.
Can anyone help me in getting solved my problem.
Thank in advance.
Regards
Jetli

if you have several projects in a solution that all compile to individual EXE's what do you do with version numbers?... keep them all in line with each other or have each EXE with its own independent version number?
|
|
|
|
|
I'd say that's up to the conscience of the individual church-goer. But it makes sense to me to have all different ones - why would the version number change on one part of the project, just because you updated another.

Two version numbers are within each module : File Version and Product Version.
We tend to let the File Version float depending upon the particular module.
The product versions typically are all the same for all modules of a particular product release.
This way, you can look at a DLL, for eexample, and know which version of the DLL you have and also which version of the product it was intended to work with.

thats a very good idea, thanks! I have always just automatically given them both the same version numbers, without actually thinking about why there are two different fields.
