I'm trying out an MFC extension DLL... An article said is all i have to do is to insert the dll header files onto stdafx.h.. Thats what i did, and there was no compile/link errors but when i ran the program i get this message:
this application has failed to start because TheExtensionDLL.dll was not found. Re-installing the application may fix this problem
How do i fix this error?
tnx in advance 
|

|

the extension DLL is in another directory other than my project directory... Now what i did was copy the DLL on my project directory and this worked... But is there anyway i can reference an extension dll outside of my project directory? where do i set it?

try Project / Settings / Debug / Category=Additional DLLs. that's for VC6. i'm not sure where the equivalent setting is with VS.Net.

From a very technical standpoint, how does SendMessage work?
Can the responder to the message run in my thread?
Or do I block until his GetMessage handler completes?
This is in response to doing some Video For Windows stuff, where you create a child window via "capCreateCaptureWindow" and control it via API's (which are really SendMessage calls).
It seems that doing this, really does make a difference (in this case)
try {
if ( ::IsWindow(hWnd) )
SendMessage( hWnd, ... );
}
catch ( ... )
{
// ...
}
From debugging this, I do see VideoForWindows and some AVI in my stack...
I am just looking for some confirmation on this topic. Any helpers out there?

You block until the GetMessage handler completes.
You can use PostMessage if you need to continue processing but then you need to think about possible synchronisation problems.

ok -- that's basic SendMessage behavior -- but can the responder run in my thread?

i want to know how can I get the unique file identificator from each file my computer the one that looks like this: 72777ASDHJ7283673 bla bla bla it is

MD5 has nothing to do with files on a computer. The latter can be used as input to the former but that's where the relationship ends. In short, MD5 takes as input a message of arbitrary length (e.g., filename) and produces as output a 128-bit "fingerprint" or "message digest." Google for "MD5 implementations" and you'll find plenty of information.

I am not sure if it is called md5 but I see that my firewall asks me averytime if an application wants to start and shows me this md5 or what is it. I realised that is different everytimne because each time I recompile a program in VC++ the firewall asks me over and over again but with a different ID. I don't beleive that tihs ID is generateed by it automaticaly because that would be absurde. I mean how does it know it is a different file. Can someone please help me now ?

MD5 changes -> the file (i.e. its contents) has changed

Is there any value in doing this?
try {
if ( ::IsWIndow(h) )
::SendMessage( h, ... );
}
catch ( ... )
{
// ...
}

No.
None of those functions throws any exceptions.

How can i send bytes through LPT1 in a WinXP platform

Any number of ways. For example:
FILE *pFile = fopen("LPT1:", "w");
fprintf(pFile, "Hello World!\n");
fclose(pFile);

Without actually trying it, I can't say for sure.

Not all the features of VC++ 5.0 appear to work with XP and help does not work at all with SP2 without a lot of fiddling. So it seems that MS is trying to push me to purchase new software. VC++ 6.0 is impossible to find, so I may as well go for the latest MS offering. .NET seems to be the route MS wants me to go. I do not want to loose my MFC and C code. In fact I only use C++ for the GUI and C for the donkey work. What alternatives have I got? Any help would be appreciated.

me think it's about time you upgrade ( how old is VC5 ? )
I don't think you will loose your code, at worse, some MFC code was deprecated ( from VC5 to VC 2003 ) and you will need to fix those issues; also there might be a ton of new warnings and compile errors that may appear.
for other alternative, I don't think there are if you need to still work with MFC.

We're in the process of upgrading from VC6 to VC7. The MFC GUI app I work on may not benefit (much) from the upgrade - in fact resource editing promises to be a bit painful in VC7 from what I've heard, although the compiler and STL support is much better.
In any case, you should definitely move from VC5 to VC6 (SP5). As someone else has pointed out, you can buy a copy on EBay. It's also still very much part of the MSDN subscription. VC6 is definitely my favorite IDE.

I can't tell you how bummed I am about having to move to VC7.  Turns out the rest of the product (which is non-GUI) is upgrading their compiler, hence the requirement to standardize.

Hi, I'm another one still using VC++ 5.0 and yes, the online help does not work since installing XP SP2. Can you please elaborate what sort of fiddling is required to make the online help/docu work again ?
Thanks,
Siggy
