You told me that it's better to use UNICODE all the time.
What if the Win32 Api function doesn't have a UNICODE version.
For example CryptProtectData() takes a BYTE (DATA_BLOB *) which is an unsigned char?

Working in Win32 console app (VS 2010) I have been trying to convert several Unicode (UTF-16) C++ functions to Ansi C (UTF-8). The test app includes two tokenizer classes, each of which work perfectly well in their respective environments, CTokA and CTokW (UTF-8 and UTF-16).
A problem arises when I attempt to run the UTF-8 functions when the Character Set properties is set to 'Use Unicode Character Set' in that std::string manipulations do not perform as expected, e.g.,
printf("start
");
gets reproduced as
printf("start
");══════════ ²²²²
Attempting to null terminate the string where it is supposed to end simply results in a space in that position and the garbage end persists, e.g.,
printf("sta t
");══════════ ²²²²
Code:
sline[11] = 0x0000;
If I attempt to change the Character Set property to 'Use Multibyte Character Set' or 'Not Set', the app will not compile and hundreds of errors occur. Of course, I can eliminate all of the UTF-16 code, but it strikes me that it should not be necessary. Perhaps if M$ made everything UTF-16 without all of the necessary decorations like 'L' and '_T(', life would be much simpler. Unfortunately, I have a very extensive UTF-8 app under 10 years of development that works quite well, but my UTF-16 (Unicode) conversion doesnt work as well because of the mixing of pointers (I think), so I have had to revert much of the code back to UTF-8. (All of which has nothing to do with my question but is simply psychotheraputic for me to ventilate on.)
My question is this: Can UTF-8 and UTF-16 code coexist in a single Win32 console app?
I have some code that was compiled without Unicode turned on in the Preprocessor Definitions. I need to access an API that had Unicode turned on in the Preprocessor Definitions (I believe that it is on by default for DLL's) .
I need to call a function in the DLL that requires a structure like:
struct READERINFO {
TCHAR serial[32];
TCHAR altSerial[32];
TCHAR name[32];
TCHAR fccId[48];
TCHAR hwVersion[16];
int swVerMajor;
int swVerMinor;
char devBuild;
};
It returns some information in the structure some of it is Unicode based however the program that is calling it is not Unicode. The preprocessors are not turned on because if they were there would be a lot of things to change in this code. The code is old code that I inherited and now I must interface to some new devices.
I declare my structure as :
READERINFO info; Then I call the function in the DLL which looks like: ApiGetReaderInfo(hAPI, &info, sizeof(into));
Which is defined as:
ApiGetReaderInfo(HANDLE hApi,
Struct READERINFO * ri,
DWORD riSize);
Parameters:
hApiHandle to valid Api object instance
riPointer to the READERINFO structure.
riSizeSize of ri structure in bytes. Usually: sizeof(struct READERINFO).
When I call it from my program that does not have UNICODE defined in the Pre-Processors I get :
Characters like : ÌÌÌÌÌ in the TCHAR fields and invalid numbers in the integer fields.
int ModuleVersion(HANDLE hApi) {
struct READERINFO info;
ApiGetReaderInfo(hApi, &info, sizeof(info));
[Code] ....
When I call it from my program that has some sample code just for this and has the UNICODE defined in the Preprocessors it works just fine. how I can call this from my old code and get the correct information. I have already tried to do the follow without success:
int ModuleVersion(HANDLE hApi) {
#define UNICODE
struct READERINFO info;
#undef UNICODE
ApiGetReaderInfo(hApi, &info, sizeof(info));

My problem is: I put the size of char array txtbuffer=[200]. If I have a editbox bigger than that, I'll get a error. In (editlength) I have the correct length of edit box. But I cant initialize my char txtbuffer[editglenth]=NULL cause editlength is a integer not constant.
I understand including the comctrl32 lib and header. I know to init common controls. I can create a tab window and add tabs to it.

I am pretty new to windows programming, but i get around with small applications.
Now I want to create a window with 10 push buttons, and was just wondering if there is some smart way, maybe in a loop to create multiple buttons.
Also, on a very populated window, is there a way to maybe have the WM_CREATE commands stowed away in another cpp file? Just for readabilty.
I have a Win32 C++ application which works pretty well, but I don't like the GUI and I want to replace it with one designed graphically, a la Windows Forms. What is the best strategy to port my code? I tried creating a new Windows Forms C++ application and got pretty far with it, but was stymied when trying to call my unmanaged functions on a button press. If I can't use Forms to add a GUI without completely rewriting the program, what's my best bet?

For some reason, the icon fails to load. I ran a breakpoint at the line for the hIconSm and got this error for the variable:
Code: CXX0030: Error: expression cannot be evaluated
The icon image is in the source folder and was compiled via ImageMagick. Google is not giving me any info regarding the error and the icon combined.
I am using visual studio 2012 on windows 7. but, when I have compiled my programs and run them on an older pc to test out its functions, I receive an error saying that the program is not a "valid win32 application." I have even tested this with a very simple hello world console application, but the problem still remains. Where is the error coming from? is the application corrupted during transport? (upload to internet) or are programs compiled on win 7 incompatible with win xp

I understand how to do that and I can do it, but I'm not totally sure how to get it to render inside of a static control(or any control). The idea is to have a gui built around an OpenGL view. how I could render inside a static or custom win32 control?

But I can't, it went so fast so long as I switch from VS to the application program, the breakpoint is hitted again, then the application is frozen again. I don't know how to setup a conditional breakpoint.

View 4 Replies View RelatedI can tons of information by calling DeviceIoControl (such as device ID, device description, whether it's connected or not) since I couldn't do it all with WMI. But I haven't figured out how to get from DeviceIoControl the info that a call to WMI's Win32_PortConnector gets. Are there any calls, directly to DeviceIoControl or something else that for a given device ID or device description would get the PortConnector information?
I would have used a combination of Win32_PortConnector and DeviceIoControl calls but the trouble with PortConnector is that it doesn't provide any information that would allow one to figure out which device ID it belongs to. Why do I need to do this? Because I'd like to get a combination of all the information the two methods provide for a given device such as a USB port, and all I'm getting from Win32_PortConnector is these scant few fields with no other clue:
string Caption;
string ConnectorPinout;
uint16 ConnectorType[];
string CreationClassName;
string Description;
string ExternalReferenceDesignator;

My setup is as follows:
There is function written C++, that must be compiled to DLL. This DLL is linked to some CAD (computer aded design) tool, that has special interface for it.
I want to add to this function some GUI (graphical user interface). So the creation of a window is necessary.
I've tried already with Win32, but without success.
The problem is that CreateWindow function requires application instance handle, that is provided by Windows itself when window is created in "normal conditions".
I know that if the structure doesn't fit into the stack, it needs to be put onto the heap. But what is maximum size of a win32 stack in usual case?

I've gotten the write part to work, but now I need to be able to read that file back in and display it as a string.

I have tried everything to fix it.
For example if using FindFirstFile(...) it assumes your passing LCPWSTR and not LPCSTR.
I know I can use FindFirstFileA or FindFirstFileW so what is point of default if always UNICODE.
Which brings to my second question. If I say
FindFirstFile("C:", &fdat);
I get error cannot convert parameter 1 from 'const char [7]' to 'LPCWSTR'
I could say WCHAR fName = "C:"; and pass this variable instead. However is there a way to cast "C:" on-the-fly to LPCWSTR, I tried,
FindFirstFile((LCPWSTR)"C:", &fdat);
But it outputs a stream of LONGs to the console instead of filenames.

I need to read Unicode characters from a file. The only thing I need to do from them is to extract their Unicode number.
For example if file has u I need to extract its corresponding Unicode number.
