You're going to have problems there...
sizeof(nCharsToPad) equals 4 on a 32-bit build....is that how many bytes you want to allocate?
Even if you fix it, you need to add one char for the NULL terminator.
nCharsToPad is an ambiguous name to me...is it the number of characters to add to the string
or the desired string length?
It also looks like you're padding the left and justifying the string to the right. PadLeft sounds like a more
appropriate method name.

i see what your saying. The SizeOf is takeing the size of the actual datatype and not the actual value? to make things correct i should do
strPadResult = (char*)malloc(nCharsToPad + 1);
nCharsToPad is the total length of the string after it is padded. I guess it should be changed to make things more clear.

Yes.
Also, why did you implement a padleft when you originally asked
for a PadRight implementation?

haha, sorry about that. I got a little confused;P. I figured Pad'Right' was when you put your pad on the left and push the orignal value to the 'Right'. I knew String.PadLeft or String.PadRight was what i was looking for in c# i just assumed padright was the one. Sorry for the confusion in this thread. Next time i'll be sure to make things more clear in the future!:->

With something like:
char *padRight( char *pStr, int nLen )
{
char *pTemp = new char[nLen + 1];
sprintf(pTemp, "%-*s", nLen, pStr);
return pTemp;
}The calling function would need to delete the memory using the delete[] operator.

See, I have this car physics simulation that uses SDL. I've placed all the lib and dll files in a sub directory and I'd like to have so that anyone can just double click the exe file and play around with it without having to copy any .dll's to the system32 directory or anywhere.
Now in the project properties > Linker > Input > Additional Dependencies I'm specifying SDL.lib (along side other libraries) and providing the relative path for SDL.lib in the project properties > Linker > General > Additional Library Directories. That works fine on my laptop because I have the SDL.dll in windows > system32 but if I copy the directory to a different computer it complains about not finding the SDL.dll and that reinstalling might help fix the problem.
So is it possible to tell it to look in a different directory than the system32 for dll's ? if so, how do I do that?
P.S. I'm using visual studio 8.
Many thanks,
Hasan.

Can LoadLibrary () help you?
I use third party dll in my programm and I dont need to copy it in system32 folder, but DO in the app folder. So you can make it running from your application folder. Or just another fixed folder and specifying it when loading.

Thanks Nelek, I'll give it a shot as soon as I get back home,
by the way, I never realised that the path of the exe is the first search path for dll's, I've been able to run the exe just by placing the SDL.dll next to the exe but I guess doing it with the LoadLibrary () would look much better.
Thanks for the help

Actually, as far as I know, is the actual path (when File.. Open.. it changes) the first one searched. By default is the App-Path when nothing changes it during execution time.

I eventually used the SetDllDirectory ( )... much easier than LoadLibrary ( ).
this is how it looks like:
SetDllDirectory(L"../dlls/SDL-1.2.12/lib"); // No idea what the 'L' is for
It worked out fine so thanks everybody you for the suggestion..

Hi!
A user maximizes the application on monitor #2 and then exits the program. When starting up again, trying to maximize the window using ShowWindow(SW_MAXIMIZE) maximizes the window on monitor #1, instead of the expected #2.
Is there any way to set the preferred/active monitor? Optimally, a subsequent call to ShowWindow(SW_MAXIMIZE) should then maximize the window on monitor #2.
Thanks and best regards
Dominik

Yes, use GetWindowPlacement to record the window max/min state, size, and monitor when the app exits, store the returned struct as binary data in the registry (or elsewhere), and the use SetWindowPlacement when the app boots the next time. Don't forget to handle bizarre situations as when a user discards a monitor or changes screen resolution.

Has anyone implemented secure IPC? I need to implement something in native code, and I need some direction.
Is there a way to have my processes dynamically generate public/private key pairs and use that kind of encryption?

The CryptoAPI[^] tools have worked well for me. They're high level APIs
so relatively simple to use.

hi all
I need to change picture in my dialog, when user push some button.
it is firts time when I use Picture control im my dialog.
help me if you can.
|
|
|
|
|
Are you using MFC or straight Win32 APIs?
The basic steps are:
1) respond to button press
2) load a new bitmap for the picture control
3) set the picture control's bitmap to the new bitmap
Which part are you having trouble with?

I have problem with step #3 I cant replase bitmap .

thanks
I Find in MSDN class CStatic and I solve my problem using this class.

If you want to set picture to a control like Static you can use of SetBitmap that it gets a hbitmap for parameter and also use of LoadImage or CImage class for load image.
