What's the problem with that ? You also have to distribute your application on every machine.
If you really don't want to install vcredist_x86.exe on every machine, you can still link statically to the MFC (if you use them) and to the C-runtime library.

If you installed it on one machine to get your app working, why would you think that it would be any different for the other 19 machines?

If running the redist installer is something you want to avoid, the only other choice is to statically-link any libraries you use (MFC, CRT, etc.)

I am having an application where there is 17 dialogs. now i need to change the size of the font throughout the project. is there any way to do that. i am aware of changing the font using the dialog properties. doing so the whole layout changes. i want to avoid that. is there any other way?

Dialog layout is based on the font so there's no way around it.

so what u mean to say is i need to change the layout manually if i change the font.

If you don't get the results you want, then yes.
Do you know the font you want to use at design time or will it
be picked at runtime?

Hi,
in my application I have to support single instance functionality I tried with FindWindow and sendmessage but it failed in some times so I want to try with mutex,can anybody suggest me how to support single instance with mutex?
Thanks in advance....
|
|
|
|
|
you can add some code like this... in your application initinstance
HANDLE hMutex = CreateMutex( NULL, TRUE, "MyMutex" );
if( GetLastError() == ERROR_ALREADY_EXISTS )
{//application is already running. dont proceed further
CloseHandle( hMutex );
return FALSE;
}
|
|
|
|
|
since w2k sp4 it is better to use global mutexes:
HANDLE hMutex = CreateMutex( NULL, TRUE, "Global\\MyMutex" );
to aovid conflicts in multiple sessions.

Error 2 fatal error LNK1120: 1 unresolved externals C:\Users\Google\Documents\Visual Studio 2005\Projects\HMSv10\Debug\HMSv10.exe
i have looked up LNK2001 error code on MSDN website but no solution for this situation. Can any1 help me solve it ?
but when i use vs 2005 to compile i got LNK2001 error, but when i use vs 2008 to compile , i got no error, this program run normally ?

I don't know what you saw there, and what you tried to fix that out, but :
unresolved external symbol "private: static class std::list > * Hotel::_rooms"
means that the compiler knows the definition of your class (in its .h file most probably), but the implementation is not foundin the directoried the linker is searching into.
do you have the implementation file somewhere else ?
is it an external library ?
if so, you certainly missed to had its path in the linker settings of your project...

Hi,
I just combinated all code into once file as you saw at http://www.in4iste.com/hms.txt
But when i use vs 2005 to compile i got LNK2001 error and when i use vs 2008 to compile , i got no error, this program run normally.
im a new in c++, please help!

Looking at the code you posted earlier, Hotel::_rooms is a std::list (I don't know a list of what because the < and > symbols were treated as html tags and disappeared). I'm not sure, but it looks like it is a pointer also. Is that what you want instead of just having a list object ?
Anyway, as I asked in my previous post, static variables need to be defined in a cpp file. Do you have something like this:
std::list<...;>* Hotel::_rooms = NULL;
in your cpp file ?
|
|
|
|
|
Yeah,
the full code of that: std::list<room> Hotel::_rooms = NULL;
but when i put that line into my cpp file, i got "Project : error PRJ0002 : Error result 31 returned from 'c:\Program Files\Microsoft Visual Studio 8\VC\bin\mt.exe"
I have used the "No (/INCREMENTAL:NO)" link option to solved this error
Thanks You!

Hi,
How do I show a button a button in pressed state using CMFCToolbar. I remember I can be done quite easily using CToolBar by just using the SetCheck function
I am trying to change the style of the button to TBBS_CHECKBOX initially when the button is created and then xor the style with TBBS_CHECKED when the button is pressed but somehow it is not working
So any body has any idea?
Thanks
Farhat

If I understand what you're trying to do right, I'd just do it using the ON_UPDATE_COMMAND_UI handler for that button and call pCmdUI->SetCheck() to whatever state you want the button to be in. That works fine for me anyway.
Hope that helps.
|
|

|

Hello!
And may be you know also how can I check the button state, is it preessed or unpressed? There is no GetCheck method by CMFCTollBarButton class. So what is the way then?
Thanks a lot in advance.
|
|
|
|

As far as I know there isn't a way to do it like that, but that's because updating buttons on toolbars is different to buttons on dialog boxes.
To be honest, I'm not really sure I understand what you're trying to do - because you handle the OnUpdate function for that button (which is the only way to set it as checked), you must know the whether the button is checked or not already?
