Hi all...
I'm looking for a good toolkit (with source) that will help me build a character based user interface for console applications using C++ in Visual Studio 2005. I'm doing a retro app, and I can't seem to find a good tool-kit that will let me define windows with different characteristics (allow word wrap, scrolling, borders, etc) and (preferably) use ANSI escape code graphics. Anyone know of a good one? I kinda want the source to go with it, so I can muddle around with it and see how they do things (doesn't everyone?). Appreciate any help...

Does anyone know of any methods for successfully reading an Excel worksheet that has been copied to the clipboard? It would need to be in BIFF8 format.

Hi,
I have a CListCtrl derived class, where I want control over the subitem painting. The control is in report mode with some subitems. The insertion of items seems to work but nothing appears in the control since I draw all the subitems myself. I figured out that the subitem prepaint stage is never called. The item prepaint stage on the other hand gets called.
What could could be the reason for this problem ?
void CXListCtrl::OnCustomDraw(NMHDR *pNMHDR, LRESULT *pResult)
{
NMLVCUSTOMDRAW *pLVCD = reinterpret_cast<nmlvcustomdraw *="">(pNMHDR);
// Take the default processing unless we set this to something else below.
*pResult = CDRF_DODEFAULT;
// First thing - check the draw stage. If it's the control's prepaint
// stage, then tell Windows we want messages for every item.
if (pLVCD->nmcd.dwDrawStage == CDDS_PREPAINT)
*pResult = CDRF_NOTIFYITEMDRAW;
else
{
if (pLVCD->nmcd.dwDrawStage == CDDS_ITEMPREPAINT)
// This is the notification message for an item. We'll request
// notifications before each subitem's prepaint stage.
*pResult = CDRF_NOTIFYSUBITEMDRAW;
else
{
// ***** This block of code gets never called. *****
if (pLVCD->nmcd.dwDrawStage == (CDDS_ITEMPREPAINT | CDDS_SUBITEM))
{
// This is the prepaint stage for a subitem.

}
}
}

How can I record and play sound file in mp3 format ?
|
|
|
|

I assume you mean programmatically...
For capturing and rendering audio samples there's
(included with Windows):
Windows Multimedia Audio[^]
DirectSound[^]
For compressing/decompressing PCM samples to MP3 you
could use the Audio Compression Manager (ACM)[^]. You'll
need an ACM-compatible MP3 codec to use ACM.
There's no MP3 codec included with Windows, but there's
some available from 3rd party sources. Google "LAME MP3"
for an example of a free MP3 codec.
You may find other open-source MP3 projects that have code that
is simpler to use than ACM.
You could also study MP3 compression and write your own codec code.

.NET has a function called String.PadRight. how can i duplicate this in win32?
thanks in advance,

Something like this maybe (not tested!)...
LPTSTR MyPadRight(LPCTSTR pSrcStr, int nNewLen, TCHAR padchar)
{
int nNewStrLen = max(_tcslen(pSrcStr) + 1, nNewLen + 1);
TCHAR *pNewStr = new TCHAR[nNewStrLen];
_tcscpy(pNewStr, pSrcStr)
for (int i = _tcslen(pSrcStr); i < nNewStrLen - 1; ++i)
pNewStr[i] = padchar;
pNewStr[nNewStrLen - 1] = _T('\0');
return pNewStr;
}

Hey Mark, Thank you for the reply. I set up a similar function to the one you posted but for some reason when i pass the integer looks as if it isn't even initialized. I am passing 15 as the value but when i check it in the debugger it is 13045942 . What can i be doing wrong?
the signature for the function is like this:
static char* PadRight(int nCharsToPad, char *strToPad, char chPadValue);
and i'm calling it like this:
StringHelper::PadRight(15, "padMe", '0');
Thanks again,

its wierd. everytime it is a different value. if i pass 15 it shows 1314822 in the debugger if i pass 10 it shows 13438982. I'll keep searching, mabye i might find something if i do i'll post it here.
Thanks Mark

Without seeing your implementation, I have no idea.
How and where in the code are you checking the value?

below is what i have for the header file. Also, i uploaded a Screenshot[^] of the implementation. i know the padright isn't correct yet but i haven't been able to test it correctly. how i am checking it is by breaking into the debugger and mouseovering the nCharsToPad. Now that i look at it furthur none of the parameters are right. The screenshot shows the values in the watch window.
namespace Server {
class StringHelper {
public:
static char* PadRight(int nCharsToPad, char *strToPad, char chPadValue);
};
}

That error looks like a corrupted stack to me. I would check locally declared vars (especially arrays) in the function calling your StringHelper

i think found out what it was (thanks to the help of you two). When i compiled it in 'release' it was messing all of the variables up when i would check them in the debugger But in debug it would look fine. At that point i knew it would have to of been something in my project settings so i went through and compared everything between 'debug' and 'release'. The culprit is in C/C++ -> Optimization -> Optimization. It was set on 'Maximize Speed (/O2)'. when i set it to 'Disabled /Od' everything looked fine. It seems like the program still works fine when the compiler is set to /O2 you just wont be able to see your variables while your debugging.

Also be careful - if your string needs to be NULL-terminated and you're not using
an ASCIIZ as a pad character...
your function doesn't NULL-terminate the string.

Hey Mark, Thanks again for the help. Below is what i have for the padright function (tested it and it seems to work). It might not be the most effecient thing in the world but i'm just a little C# programmer trying to harness the power of C++. I've only been working with Unmanaged C for a week now
char* StringHelper::PadRight(int nCharsToPad, char *strToPad, char chPadValue) {
char* strPadResult;
int nCurLen = strlen(strToPad);
strPadResult = (char*)malloc(sizeof(nCharsToPad));
for (int i = 0; i <= nCharsToPad - nCurLen;i++) {
strPadResult[i] = chPadValue;
}
int nIndex = 0;
for (int j = nCharsToPad - nCurLen; j < nCharsToPad; j++) {
strPadResult[j] = strToPad[nIndex];
nIndex++;
}
strPadResult[nCharsToPad] = '\0';
return strPadResult;
}
Thanks again!

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.
