Never declare anything after using DECLARE_MESSAGE_MAP or DECLARE_DYN* (all the MFC macros) without resetting your access. They change the access setting of your class.
Place a new "public:" prior to the definition of SetAppState and GetAppState.
(Well, that and fixing the _MODE problem which you have already done.)

My version information is stored in MyProject.rc under the VS_VERSION_INFO . I also have a defined variable with the version info as its value that I use for an about section of the program. Is there a short way (maybe only a few lines of code) to set the File's Properties Version Tab to the value of that variable (i.e. change FILEVERSION and PRODUCTVERSION in VS_VERSION_INFO)? Basically so I don't have to go into the VS_VERSION_INFO and change it each time myself. So on build it reads the variable's value and changes the VS_VERSION_INFO automatically...

No, I don't want it to actually auto increase the version numbers each time i build the executable. I simply want the key (ie FILEVERSION) to read the value of a variable within the code that I define; so I don't physically have to open up the resource file and change the key for the version in VS_VERSION_INFO. You follow what I mean?

That article wasn't meant to be a total solution to your problem. It was merely to show you what was invloved in operating on a project's .rc file.

{<br />
szAppVersion = _T( "Version ");<br />
szAppVersion += lpVerInfo;<br />
SendMessage( GetDlgItem( IDC_VER ), WM_SETTEXT, NULL, (LPARAM)szAppVersion.GetBuffer(MAX_PATH) );<br />

<br />
}<br />
}<br />
GlobalUnlock( hMem );<br />
GlobalFree( hMem );<br />
You need a IDC_VER in your dialog that you want to display that information into.
You can also get the strings from other parts of the versioning by using the following:
<br />
VerQueryValue( (LPVOID)lpstrVffInfo, <br />
TEXT( "\\StringFileInfo\\040904B0\\LegalCopyright" ),<br />
(LPVOID*)&lpVerInfo,<br />
&lpVerInfoLen ) <br />
<br />
VerQueryValue( (LPVOID)lpstrVffInfo,<br />
TEXT( "\\StringFileInfo\\040904B0\\CompanyName" ),<br />
(LPVOID*)&lpVerInfo,<br />
&lpVerInfoLen )<br />
Hope this helps

Hey people, I'm developing an application that gets SMS's from a GSM modem and uploads them to a DB. To do this i'm using a CInternetSession object. The app compiles OK but I get a Debug Assertation Error!. I think it has something to do with the internet session object because if I comment out anything to to with the CInternetSession then i don't get the debug error. Infact, simply the 'CInternetSession InternetSession;' declaration at the beginning causes the error alone.
Here's the code. sorry about the spaghetti style code - i'm a bit of a newbie to C++

When the assertion fires, it tells you the line number and file of the offending statement. That should give you a big hint.

Thanks David,
I looked at that and it refers to line 31 of some MFC file. When i press retry on the debug assertation window it refers to getAfxAppName() at line 31 of that file with a yellow arrow in the call stack window. Also in the call stack window is a green arrow referring to line 22 of the code that i posted which is the 'CInternetSession InternetSession;' declaration, and refers to a $E4() method. There is also a window that comes up showing an 'Unhandled Exception' which i'm guessing is what the $E4() is. Any ideas on what to do with this exception?

It would help to also know the name of the file.
Are you using Visual Studio v6 or .Net?

Hi,
Just initialize the CInternetSession Variable with a name.
For example, CInternetSession x("MY APPLICATION");
That should solve your problem.

Hi,
Attempting to use PlaySound and sndPlaySound on a Win CE PocketPC. The API call returns to say it is a happy chappy and all is well, but I certainly don't get the specified .wav file played  ! The file name is correct etc etc
Any idea's?
Interestingly, when I try and play .wav file from Windows explorer they don't sound either.... probably a clue there..!
Thanks

Hai Frens,
I need a help regarding MFC.
weather Forms can b inserted in the SDI.
I need to know How to insert with out using App Wizard.
I had an application where in all r programmed by my own With out using app wizard. Which is an SDI application. Now i am in need to insert few controls in that, i Hope With out forms Controls Can not b inserted.
So, Kindly Help me to insert Forms in SDI.
Bye

AppWizard is used once to create the initial project. After that, you can manually add classes to the project via ClassWizard. To add controls to the dialog template(s), select the ResourceView tab in the Workspace window, expand the Dialog item and double-click on the dialog resource you want to add controls to. Make sense?

Hi
Does anyone know how to get the list of USB devices connected in machine through c++
thanx in advance
|
|
|
|
|
We use sdiGetClassDevs, which takes the GUID for various USB devices, and then SdiEnumDeviceInterfaces on that to get each one. Then SdiGetDeviceInterfaceDetail will give more info. There are other functions in the same area that might be interesting to you.
Unfortunatly our compiler is too old to support the calling conventions used the actuall functions, so we have some wrappers. (there are historical reasons why we don't have a better compiler) You will need to figure out what the windows names for those functions are from those names. As I recall a search MSDN for those names will turn something up.

As always, programs change. My application started as a stand alone app. In the latest change, the request was made to ad COM support with my app becoming the server. The client can open my dialog boxes. It took some time, but it is up and running. The displaying of dialog boxes and most of the error messages get sent to the new client.
The problem is now: On DDV_ the validation does a display of a messagebox using AfxMessageBox() this goes directly to the active childframe of my app. The other error messages were replaced by ::MessageBox() where I can specify the window handle.
How must I tackle this sneeky little problem? Any advice appreciated.
Greetings,

AfxMessageBox() calls the virtual function CWinApp::DoMessageBox().
Override it and call ::MessageBox with the parameters you want.
