Thanks i will read all of that, it's not as simply as c# ^^.(i must remember DWORD is unsigned, it's more simple with c#, with int or uint,...). I just saw it's a byte value furthermore.
It's true for the function. I think to myself it was implicitly said, but it's true that for the one that never seen it before i should think to put the function.
I was working about how use handle and reference, it's more easy in c# about that.

You are welcome.
Not sure if you know this... but the username you are using on codeproject perfectly translates to 'Master/Leader of asking questions' in Middle English. Even the alveolarized double nn is period and would indicate that the vowel e is pronounced as a monophthong.
It's probably just a coincidence. But I thought I would mention it.

lol , i didn't know it, it's cool to learn something new. I took this username on google with reference to The big Lebowski's movie, i'm pretty sure it's a wrong translation. Perhaps it's dude in english but in french he wants to be called The Duc, what is a total paradox with all of he is. It's true that it could interpreted as something pretentious, i'm happy you understood it was not at all for this reason. It's interesting to discover a particularity of another language.
Thanks for all, sinceraly.

Hi,
I have a successful Laundrette and Dry Cleaner application written in CPP, and MFC. It is more than 20 years old now.I want to start afresh again, this time using cloud storage. I have the 20 year experience of how such application should work in real time. I now want to move to "The Cloud" for data storage and licensing to get paid. Any suggestions on how to get this started.
Bram.

What kind of data are you going to store in the "cloud"?
|
|

|

Hi,
Well Ideally, sets of binary data of my own design, but, essentially a set of databases relating to a number of different customers, who will hold their archives and trading records there, There will also be a number of PDF's and jpeg's, facsimiles of identification documents to comply with local money laundering legislation.
Regards,
Bram.

What happens if the internet connection goes down ... business stops? Nobody gets their clothes back? I'd use "the cloud" for backup, not as a primary.
Same application ... just sync to the cloud periodically.

Well, the same ass what happens currently when the electricity goes down, or a disk fails. These things have happened. We close the shop, and indeed on those rare occasions, people get their clothes back via a manual system, but, payment is not asked for. Actually Handing in far processing is far more challenging. We would require an automatic sync at least 10 times per hour.

You need to find which cloud storage you want to use (google, amazon...)
Then look at the API/SDK they offer.

Well, is there a list of smaller providers? or Intermediaries?

Is there any way I can configure Visual Studio 2019 so that when I build the solution, it automatically builds a 32 bit and a 64 bit version of the same native project at once?
It's a pain to have to keep two different projects in sync to build two different executables.
The difficult we do right away...

You could always have VS build the x86 version and create a PostBuild event bat file and run the MSBuild command line to build the x64 version.

Thank you Victor!

I spend most of my development time using 64 bit Debug, but have to build both 32/64 and Debug/Release and test before I check in. I call MSBuild from a batch file to build everything. My dev environment is highly customized, and have a post build deployment script that runs and updates all 4 installations automagically to 4 different VMs that I have our products running on. At the end of each build, it triggers automated testing on each of those VMs.

Look at the line that gives the error message, or the one before it:

You could create two projects in the solution, one windows and one raspberry. Add the same source code to both projects and you should be able to build both together.

Maybe there is a setting for this or a utility or what not. I've been tracking down a buffer overrun and loss of data for a few days, and I have discovered that a data structure pretty clearly defined is blowing past it's size. I think it's due to silly datatype selection and not understanding padding.
I'm working in VS2008 (no choice), and I've yet to find something to help me understand the exact byte layout of a structure. I really need to see the padding being added. The fact that I have a mix of unsigned ints, bools and bytebools can be attributed to ignorance and just poor programming.
This seems to me something any IDE should be able to show me, but if you recall, Microsoft just broke help in VS2008. I was thinking the map file, but I'm not seeing it. What I would like to be able to do is to add a watch to the data structure. In the watch window, I want to see the addresses of each item in the structure by expanding it. But I think I'm going to have to do a lot of typing.
Appreciate any pointers.
Long weekend ahead.

I'm not sure why you'd be having data overruns, assuming you're sizing any I/O or copying correctly. Even if you have an "anonymous" buffer (e.g. char *), that you're copying your struct from, things should still work correctly with the appropriate sizeof operator in use.
I don't know of any tool within VS that will give you the information you need, but you might get some mileage out of [pack pragma | Microsoft Docs](https://docs.microsoft.com/en-us/cpp/preprocessor/pack?view=msvc-160), and or [offsetof Macro | Microsoft Docs](https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/offsetof-macro?view=msvc-160). Either or both won't save you from some typing though.
I think you need to be careful with #pragma pack. X86-64 doesn't seem to have a problem accessing unaligned data, but I assume its slower to do so than correctly aligned data. Other architectures though are not as accommodating. For example, the following code works fine on X86-64 in both 64 bit and 32 bit modes (at least using linux), but gets a bus error when running under arm-32
#include <stdio.h>
#include <stdlib.h>
int main()
{
void *ptr = malloc(1024);
char *tmp = ptr;
for(size_t i = 0; i < 24; i++, ++tmp) {
long double *d = (long double *)tmp;
*d = i * 2.0L;
printf("tmp = %p, d = %p *d = %Lf\n", tmp, d, *d);
}
free(ptr);
return 0;
}
Keep Calm and Carry On
