The biggest reason programs won't run on previous versions is because the programer chooses functions that are not supported. When making your program, refer to MSDN for the api calls, MSDN lists the minimum version of windows required.

Hi WalderMort,
The only difference between the two system is that the other one does not have
visual studio 2005, so I was just wondering if this is/are one of the reason the exe I created does not run,
the exe was from a beginners tutorial from this site.
thank you

What error are you getting? It sounds as though the exe is looking for a dll that may not be on your other PC.

Well , when I run the exe file , I got the following msg
"The application failed to start because incorrect configuration. Reinstalling may fix it"
I created the exe , by using the build option on the visual studio 2005 ide, this is the correct way right?
thanks again

I see, By default VS2005 adds a manifest file to the exe, this file will prevent the exe from running unless specific dlls are in a specific directory. Try excluding the manifest from your app, or add the required dll's, in the correct directory ( sorry I can't remember which ).

No, it’s because VS2005 targets the latest C Run time. It is no longer a matter of just distributing the latest DLLs they have to be installed onto the target system. See Mark Salsbery's post for further information.

hello to everybody.
i have a problem about polynomials by using c which includes a link command to mupad. but i am new at c++ and mupad programmes, and i cant find examples about the mixture of c and mupad.
1) the c programme must be able to take the degree and constants and sensitivity of the polynomial from user.
2) the programme must be able to find a root of the polynomial with a given initial value by using Newton-Raphson method.
3) the programme must be able to sense that is subjected to multiple root, and it must be able to prevent the negativities of this condition.
4) and the programme must do the steps 2 and 3 by using mupad.
if somebody can help me about this soon, i will be very grateful.
have a nice day to everybody...

I need a way to get the name of the application owning the foreground window. I would also like to monitor this rather than constantly polling it. I assume this would involve some use of GetForegroundWindow() function and WM_ACTIVATEAPP notification but can't seem to figure it out exactly.

Retrieval:
- GetWindowThreadProcessId and obtain process ID;
- pass the ID to OpenProcess and obtain the process HANDLE (PROCESS_QUERY_INFORMATION will suffice);
- call GetProcessImageFileName on process handle to get full path of the executable file.
Monitoring (without polling):
- implement a global hook in a dll, with SetWindowsHookEx and WH_CALLWNDPROC(RET) or maybe WH_CBT; inside hook procedure, do nothing more than look for message(s) WM_ACTIVATE, WM_ACTIVATEAPP and whatever other messages you may need to figure when active window is changing; send the appropriate notification to the executable on the next point;
- implement an executable to process the notification from the hook dll;
- use a communication mechanism (named pipe for example, or even mailslots since hook dll and executable are local); the dll will write and the exe will read; anything else will do, just be careful to not break the hook dll.

I'm trying to program a dialog which has a "canvas" for me to draw lines and text.
The general idea is to have a dialog with editboxes etc for inputing line coordinates and text to display on a canvas.
Any help appreciated.

What part are you having problems with?
|
|
|
|

what exactly u seeking for ? u can draw lines on WM_PAINT messages comes. u can also draw text using TextOut or DrawText . But why you need to enter position for line ? or is it any 3d coordinates etc ?
If u can Dream... U can do it

i have to develop an application which displays TIFF images n allows the user to make it larger or smaller by using the mouse pointer. i have read how to read/write tiff files(code in c) but it really doesnt help much.
please let me know what to refer. presently am reading mastering VC++.
just a bit of push in the right direstion will be enough.

Loading and saving TIFFs is probably the biggest challenge. If you've read the TIFF specification
then you probably have an idea how big a task writing a TIFF loader/saver can be.
Windows provides GDI+[^] which will handle that for you, along with scaling, drawing, and many
other things you may need to do with bitmap images. There's lots of articles here on CP to help
get you started...search for "GDI+".
Also, a solid understanding of Windows messaging will help immensely for developing the UI
related code.

Why? Doesn't that code make the job for you?

Hi.
I would like to know what if it's possible to build an application that relies on external GUI plugins with a fixed interface ? What i mean is something like a property sheet, only that the sheet pages are loaded from external DLL's and not from the main executable.
I've tried some things, begining with invoking a modal dialog from an external DLL, and that worked fine. However, this is not what i need.
I then moved on to trying to add pages to a property sheet dialog. this action gave me some strange behavior, such as ASSERTION errors on multiple locations (wrong resource handle for example).
I would like to know if this is possible. I'm not fixated on the property sheet idea, although it is the prefered way at the moment.
I would appreciate any information you can share.
best regards,
Chen Ganir

Do you want just the dialog resources in a dll or an MFC extension DLL with the code and the
resource in the DLL? Both are possible.
|

|

Hi Mark.
Thanks for your quick reply.
I would prefer the entire code in the DLL, probably an MFC Extension DLL.
thanks for your help !

This document Extension DLLs[^] explains what needs to be done better
than I ever could  If you need to explicitly link to the DLL at runtime (using LoadLibrary)
then using exported C-style stub functions and GetProcAddress() is a simple way to go.

Thanks again for your help. i'll take a look at it and hopefully it will provide the required answers i'm looking for

Hi Mark.
I've ran into the same problems as before. i can't seem to make it work for some reason. Can i email you the code so you could take a look at it ?
thanks,

Context: In a multithreaded app, two threads share access to an object. The members of the objects class are private and are accessed through mutators and accessors that use critical sections to syncronize.
Problem: Where to put the volatile access modifier go in regards to the object and/or it's class?
Question: Should the object, the members of the objects class, or the object and it's class members be declared using the volatile access modifier?
