Use
GetLastError() method after you called wsprintf and provide the error code
|
|
|
|
|
When compling in platform win32 works. Whan compile in x64.
cannot convert parameter 1 from 'char [512]' to 'LPWSTR'
in the wsprintf call first parameter szVer.
Understand that de definition "change" för char in the call or
I have tride windhows.h and TCHAR.

check your build settings. you probably have "Multi-byte" or "Unicode" set for "Character set" on the x64 build, but "not set" on the x86 build.

Thank you.
I missed that on my project. It’s work perfect.
Some of my collage at work pointed out that change to “std::string” in the project. But still the interface to dll need to be native C with c-style string. Is std::string more neutral to the character set?
Comming from Delphi to C# world then C/C++ for this project lot of reading "new" things. My old Charles Petzold book is back on the self again. ;D

sadly, no. there is a std::wstring variation to handle wide char strings.

Can i change the code copy to the szVer in a better way that does not use wsprint. Just want the format.

You should use TCHAR for your array and _stprintf() to fill it. In that way you can compile for ANSI or Unicode without the need to change your source.

Is there a way to prevent the user from logging off from their Windows account while my application is running?

Is WM_QUERYENDSESSION of any help?

Thanks again

Method for XP or earlier is slightly different from Vista/Win7 from my experience.
For XP or earlier, return 0 for WM_QUERYENDSESSION and this should be enough.
For Vista/Win7, I haven't found a way to entirely stop logging off. But temporarily blocking logging off is possible. I would return 1 for WM_QUERYENDSESSION and register a blocking reason during WM_ENDSESSION, by calling ShutdownBlockReasonCreate. Then call ShutdownBlockReasonDestroy when your application is finished running.
You should obey the description mentioned in WM_ENDSESSION Message[^] and WM_QUERYENDSESSION[^] to make sure both user and Windows system are happy.

He he, no but the PC is running an important control system that the normal user is not authorised to shut down. However, if the user logs off, it closes my application.

Hello all,
How do you get a list of all files and folders of ALL types including system and critical ones, and files even in archives on a specific drive, and to put this string on a richtextbox or textbox.
Simple Thanks and Regards,

Not too difficult to find some suggestions[^].

You could use FindFirstFile and FindNextFile to enumerate files/folders in a specified directory/drive. Listing the Files in a Directory[^] shows an example using these two functions. You will also get file/folder attributes when the functions successfully return.
Write a recursive function so it will enumerate subdirectories.
An alternative is using Shell interfaces such as IShellFolder and IEnumIDList combined with some Shell functions like SHGetDataFromIDList and SHGetDesktopFolder. It's bit more complicated than the other one, but it's more flexible. Consider this approach if FindFirstFile/FindNextFile method doesn't fit your need.
Also, you mentioned that you need to put the list of files/folders into a box. Loading this kind of huge list of items takes a long long time using default Windows control settings. Take a look at Virtual List Control at About List-View Controls[^]. You will happy to see your executable run more smoothly than the others at the end.
You can also try to google your concerns as suggested by Richard MacCutchan. Appending your keywords with "MSDN" or "Codeproject" will normally show good results.

You can use WMI class CIM_DirectoryContainsFile to list all the files and all information you need including compression type, last date accessed, date created type, size, path and much more; all 33 different items describing each file on all the drives on local or remote computer.

Do you mean that you have an ActiveX control that is on a dialog?

int *pi;
{
int i = 3;
pi = &i;
}
std::cout << *pi << std::endl;
I figure that the *pi value in std:cout can not be trusted since i goes out of scope and the address of i can be used for other stuff. Is that correct?
Thank

Yep, that's right. It's also why you should never return references to local variables - what they're based on disappears at the end of the block they're declared in.
Cheers,
Ash

It depends on stack usage.
If you return a local var thats now out of scope to a func that eats the stack it will get munged. If not, it is still there, but its is risky of course.
Actually we found a windows bug that did just this. It returned a local var. This was OK till we hooked the func, and thus increased its tack usage.
In your case i is out of scope at code level, but is still on the stack since you havent returned from your func yet (your code is actually compiled with i on the stack just after pi).
--edit--
I see no one has responded. I guess an understanding of assembler (ie, the way code actually compiles) is totally foreign territory to todays 3G coders.
