Hi All,
I am using gethostbyname function to get ip from name. It works fine if ip is defined. But if 'Obtain ip address automatically' settings is on, this function gives some different ip. Any help please.
Thanks

The IP of what computer - your computer? A remote computer?

Where is 'Obtain ip address automatically' set - on your computer? And 'different ip' for what - your computer, a remote computer?

'Obtain ip address automatically' set - on remote computer, got different ip. 'Prefered DSN Server' settings had wrong value. After changing it got correct ip.

Which is the whole essence of DHCP. The gethostbyname() function does not care how your computer obtained its IP address.

Hello all,
I am currently doing my FYP. I download a set of header files of libxml2 with .h files and .lib files.
I first try to create a windows 32 application console application and it works fine (to ensure i link it properly)
I then head off and try to create a DLLs for the smart device, however, i return with the following errors:
Linking...
1> Creating library Windows Mobile 6 Professional SDK (ARMV4I)\Debug/TESTTESTTEST.lib and object Windows Mobile 6 Professional SDK (ARMV4I)\Debug/TESTTESTTEST.exp
1>TESTTESTTEST.obj : error LNK2019: unresolved external symbol xmlParseFile referenced in function ExportedFunction
1>Windows Mobile 6 Professional SDK (ARMV4I)\Debug/TESTTESTTEST.dll : fatal error LNK1120: 1 unresolved externals
1>Build log was saved at "file://c:\Documents and Settings\wu\My Documents\Visual Studio 2005\Projects\TESTTESTTEST\TESTTESTTEST\Windows Mobile 6 Professional SDK (ARMV4I)\Debug\BuildLog.htm"
1>TESTTESTTEST - 2 error(s), 1 warning(s)
I created my DLL like this:
#include "resourceppc.h"
#include "stdio.h"
#include "string.h"
#include "stdlib.h"
#include "xmlmemory.h"
#include "parser.h"
extern "C" void EXPORT ExportedFunction(){
char * docname = "abc";
xmlDocPtr doc;
xmlNodePtr cur;
doc = xmlParseFile(docname);
}
Being noob, i just want to know:
1. It is possible to create a DLL using .lib files ?
2. Is my linking wrong ?
Any help of somekind will be greatly appreciated !
Thanks,
Leslie

I think the issue is that you've downloaded an x86 Win32 implementation of libxml2. You're then trying to link that into a Windows Mobile DLL that's targetting an ARM processor. Now, ARM != x86, so you're going to have to find some ARM Win32 binaries from somewhere - that probably means building it from source yourself...
What;s wrong with using Microsoft's XML libraries? Aren't they bundled with Windows Mobile? If so, that'd be simpler than trying to install libxml2...

One other XML alternative (from this very site!) - PugXML[^] - it's lightweight and simple to build!!!

Hi Stuart,
Thank you for your answer first.
I know you must be wondering why we don't use the integrated XML, but it is my supervisor request (OMG ~). We are trying to build a common engine that is written in plain C and is fully operational in iphone and windows mobile environment.
Do you have any idea if there is any avaliable library avaliable ? If so, very appreicated if you could just post the link !
Thanks,
Leslie

libxml would be the best choice in my opinion, it is widely used in non-Microsoft commercial products. You should compile the libxml library from source rather than using the pre-compiled libraries. Although commonly used... the designation 'Win32' is somewhat a misnomer by being an incomplete description. It would more accurate if defined as 'Win32-x86'.
Best Wishes,

As Randor says - libxml, and it looks like you're building it from sources...see this page[^] for download links! Good luck!

Being a Noob, I just want to ask 2 more questions:
1.I have download all the header and the C files associated with the library. If I ever want to build a DLL, I only need to call the header ? (e.g. I call xmlmemory.h for the "parseDoc" function ??) Do I have to compiled all the C files and the header into a static library first ?
2. When I did iphone development, I notice that there is already a compiled .lib files in the path /usr/bin/lib (if i remember the path correctly =P ). Could I copy the .lib file ? I notice that iphone and windows mobile both use the ARMV4 processor...so the architecture should bethe same ?
Thanks,
Leslie

You need to have compiled the C files into a library - either a static library (a .lib file), or a dynamic library (a .dll file) with associated import library (also a .lib file). You can link against either .lib file, but if you link against the dynamic library version, you need to deploy the .dll file with your project.

The processor is the same, but the operating system is (very) different - you cannot use iPhone binaries on the Windows Mobile platform, as it will expect to be able to call OS X.

Another XML library you might want to consider is Expat[^], if only because it has a Visual Studio 6 project file in the source distribution that you could use as a starting point for building it for the Windows Mobile target - you'd need to change the project's target from x86 Win32 to the correct one for your WIndows Mobile target, but that should be relatively trivial.

So I'm trying to create a function that will layer all of the objects I have in the list onto a temp HDC and then BitBlt from it to the actual HDC which is passed in as hdc. If I replace the line BitBlt-ing everything to the hdcTempMem with the same statement BitBlt-ing to hdc I can see it working.
Not sure what needs to be done to get this intermedte hdc to work but it will be needed because otherwise there will be flashing when running at full speed. Anyone able to help me out?
void UpdateDisplay(HWND hwnd, HDC hdc)
{
HBITMAP oldImg;
RECT screenRect;
HINSTANCE hInst = NULL;
HDC hdcTempMem, hdcMainMem;
AniObject curObj;
int i = 0;
GetClientRect(hwnd, &screenRect);
hdcMainMem = CreateCompatibleDC(hdc);
for(objI = objects.begin(); objI != objects.end(); objI++)
{
if(objI->objectType == ANIBITMAP)
{
GetObject(objI->hBmp, sizeof(BITMAP), &(objI->bmp));
hdcTempMem = CreateCompatibleDC(hdcMainMem);
oldImg = (HBITMAP)SelectObject(hdcTempMem, objI->hBmp);
BitBlt(hdcMainMem, objI->posX, objI->posY, objI->width, objI->height, hdcTempMem, 0, 0, SRCCOPY);
DeleteDC(hdcTempMem);
}
i++;
}
BitBlt(hdc, 0, 0, screenRect.right, screenRect.bottom, hdcMainMem, 0, 0, SRCCOPY);
DeleteDC(hdcMainMem);
|

What happens if you alter this line:
hdcTempMem = CreateCompatibleDC(hdcMainMem);
to
hdcTempMem = CreateCompatibleDC(hdc); ?
Also - have you checked to see if the BitBlt operation is returning an error status or not?
Also - looking at the CreateCompatibleDC[^] documentation, it seems to me that you should be selecting a bitmap into hdcMainMem that you can draw on - otherwise (again, from what the documentation says) you only have a one pixel bitmap backing hdcMainMem. That seems to be backed up when I look at the double-buffering DC class documented here[^]. OK, it's for WTL, but it uses the standard GDI operations to implement the double-buffering.

Thanks a lot for spotting my error. It was your last point about the one pixel bitmap that was the problem. I forgot to give hdcMainMem an area to draw on. Everything worked once I added:
blankImg = CreateCompatibleBitmap(hdc, screenRect.right, screenRect.bottom);
SelectObject(hdcMainMem, blankImg);
Now I can get back to work. I think thats a good thing?....

your hdcMainMem needs a bitmap

I want to use c language function localtime() for the conversion of seconds into date.
As I have learned from someone that this function used the date 1970-01-01 00:00:00 as the base to calculate seconds into date. But when I used it it seems that it use the base date as 1970-01-01 05:00:00. I can't understand this.
Also is it possible to calculate the date from seconds by using someother base date value. for example i have seconds starting from 1994-01-01 00:00:00 to now, then how to calculate the time from these seconds (base date + seconds).
The function used by me is as follows.
void Duration_to_time(int Seconds,char OutputTime[])
{
time_t count_second;
struct tm *newtime;
tzset();
count_second=Seconds;
newtime = localtime(&count_second);
if (strftime(OutputTime, 20, "%Y-%m-%d %H:%M:%S", newtime) == (size_t) 0)
printf("Could not get string from strftime()\n");
}

localtime adjusts the evaluated time to your local one (hence the five hours shift). use gmtime, instead.

To use 1994-01-01 00:00:00 as base date, simply add the corrensponding time_t value to your duration and then call gmtime and strftime)

It actually goes back about 21600 seconds beyond that to 31-Dec-1969 @ 1800.
