I have a problem with the free instruction under win32, t raise an error when i try to free allocated memory after i allocated it with malloc, i don't know why, if the MSDN indicates that is right.
The code i use is some like this:
LPSTR lpCode=(char *)malloc(MAX_PATH);
strcpy(lpCode,lpText);
SendMessage(GetDlgItem(hMain,IDE_RTFBOX),WM_SETTEXT,NULL,(LPARAM)lpText);
free(lpText);
|

I have no idee why you're allocating memory for a variable you don't use, but when you use malloc on lpCode you should use free on lpCode too. Not on lpText, which is a totaly different variable...

Excuse me i forgot these lines:
char lpText[]="Hello world";
...
free(lpCode);
When i free the memory allocated in lpCodeit raise an error
The first example code was wrong excuse me.
|
|
|
|
|
But the line
free(lpText);
does that exists in your code? Beacause that line is wrong. Please try your code without that line...

You should try
lpText=(char*)malloc(32);
strcpy(lpText,"Hello world\n");
...
free(lpCode);
free(lpText);
|
|

SendMessage is synchronous. It's perfectly OK to use lpText as the parameter. SendMessage will not return until the receiving window has handled the message.
If you wrote the control with ID IDE_RTFBOX, and overrode WM_SETTEXT, you should make a copy of the argument there.

Anyone know how to turn it off from a WinInet-based client?
I'm getting hit by Q263754: WinInet Application Stops Responding and Shows 100-Percent CPU Utilization[^]. The problem only occurs when chunked encoding is enabled.
They recommend that you use HTTP 1.0, which doesn't support chunked encoding, except that specifying HTTP 1.0 in the request doesn't fscking work!!![^]  
Their recommendation is to change a setting in the registry to force IE/WinInet to use HTTP 1.0. It would, of course, be extremely poor form for my application to do this so is there anything else I can do?
I tried setting a "Transfer-Encoding: identity" header in my request but that causes the HttpSendRequest() call to hang

In my quest for a simple to use image loading library I came across GDI+. I only want to use the portion of GDI+ that loads images, since it loads every image type that I would ever need into a DIB (which I can extract and feed OpenGL). However, I have the most annoying and frustrating issue: the image is not loaded and the lastResult member of the Bitmap object indicates InvalidParameter. Obviously I'm feeding it something bad. The relevant code snippet follows:
<br />
xBoolean xImage::Load (char *fileName, xBoolean mipmap)<br />
{<br />
BitmapData *bmpData = new BitmapData ();<br />
Rect *rect = new Rect ();<br />
sint32 format, stride;<br />
uint32 i, j;<br />
xbyte *tempBuffer;<br />
uint32 wideLen;<br />
WCHAR *fileNameW = NULL;<br />
<br />
if (fileName == NULL)
return xfalse;<br />
<br />
wideLen = MultiByteToWideChar (CP_ACP, MB_PRECOMPOSED, fileName, -1, NULL, 0);
fileNameW = (WCHAR *)malloc (wideLen);
MultiByteToWideChar (CP_ACP, MB_PRECOMPOSED, fileName, -1, fileNameW, wideLen);
<br />
Bitmap bmp ((const WCHAR *)fileNameW, FALSE);<br />
<br />
...<br />
The string fileName is being properly translated to fileNameW as below:
<br />
fileName[0] 119 'w' char<br />
fileName[1] 104 'h' char<br />
fileName[2] 105 'i' char<br />
fileName[3] 116 't' char<br />
fileName[4] 101 'e' char<br />
fileName[5] 46 '.' char<br />
fileName[6] 116 't' char<br />
fileName[7] 103 'g' char<br />
fileName[8] 97 'a' char<br />
fileName[9] 0 char<br />
<br />
fileNameW[0] 119 unsigned short<br />
fileNameW[1] 104 unsigned short<br />
fileNameW[2] 105 unsigned short<br />
fileNameW[3] 116 unsigned short<br />
fileNameW[4] 101 unsigned short<br />
fileNameW[5] 46 unsigned short<br />
fileNameW[6] 116 unsigned short<br />
fileNameW[7] 103 unsigned short<br />
fileNameW[8] 97 unsigned short<br />
fileNameW[9] 0 unsigned short<br />
The constructor for the Bitmap object is as follows:
<br />
class Bitmap : public Image<br />
{<br />
public:<br />
friend class Image;<br />
friend class CachedBitmap;<br />
<br />
Bitmap(<br />
IN const WCHAR *filename,<br />
IN BOOL useEmbeddedColorManagement = FALSE<br />
);<br />
Recall that the lastResult member is being set to InvalidParameter. Here are the possible GDI+ return values:
<br />
enum Status<br />
{<br />
Ok = 0,<br />
GenericError = 1,<br />
InvalidParameter = 2,<br />
OutOfMemory = 3,<br />
ObjectBusy = 4,<br />
InsufficientBuffer = 5,<br />
NotImplemented = 6,<br />
Win32Error = 7,<br />
WrongState = 8,<br />
Aborted = 9,<br />
FileNotFound = 10,<br />
ValueOverflow = 11,<br />
AccessDenied = 12,<br />
UnknownImageFormat = 13,<br />
FontFamilyNotFound = 14,<br />
FontStyleNotFound = 15,<br />
NotTrueTypeFont = 16,<br />
UnsupportedGdiplusVersion = 17,<br />
GdiplusNotInitialized = 18,<br />
PropertyNotFound = 19,<br />
PropertyNotSupported = 20<br />
};<br />
It isn't that it can't find the file, GDI+ is initialized properly, and it isn't any useful error. One other thing, if I change the line
<br />
Bitmap bmp ((const WCHAR *)fileNameW, FALSE);<br />
to read
<br />
Bitmap *bmp = new Bitmap ((const WCHAR *)fileNameW, FALSE);<br />
the compiler spits an error about not finding the constructor, which I found odd. If anyone can help, it would be much appreciated.

From MSDN:
[quote]
Bitmap::Bitmap(filename, useIcm)
Creates a Bitmap object based on an image file.
Bitmap(
const WCHAR* filename,
BOOL useIcm
);
Parameters
filename
[in] Pointer to a null-terminated string that specifies the path name of the image file. The graphics file formats supported by GDI+ are BMP, GIF, JPEG, PNG, TIFF, Exif, WMF, and EMF.
[/quote]
I do not see tga in the list of supported formats.
Try http://www.codeproject.com/bitmap/cximage.asp[^] instead.

hello
This is meant as a theorethical programming question basically but if you could acompany some examples in c and vbs to your answers as examples or proof of concepts that would be lovely.
So the question is:
Can code be archived(made smaller than it actually is)?
Like for exemple could I have a function make_code_big_again that could receive as a parameter a array like structure, string wharever containing some code that was made small andmake it bigg again and run it???
or could this be done with binary files???
like could I somehow archive them, put them inside the exe in a big string or as resources and then unpack them, but withouth utilising any third paryt software like winrar or winzip cause that wouldn't make the program very platform independent.
???
thank you for your time

Sure, if the code is run on an interpreter.
|
|
|
|

something like an auto-extractable zip archive ? yes it's possible...
I think that you can find an example somewhere here on codeproject.

how to create thread in runtime
|
|
|
|
|
UINT thFun(void*){
return 0;
}
fun(){
AfxBeginThread(thFun,NULL); //starts thFun() in a new thread
return 0;
}
This creats a worker thread. There is something called UI thread also-
search cp for them ...

I have 2 parse a xml in my vc++ programs , which parser should i used , how 2 implement that.

there is very well documented Interface in COM known as IXMLDOMDocument,IXMLDOMElement which help you in parsing the XML.
MSDN has Example to show working of IXMLDOMDocument, IXMLDOMElement.

Hain Rahul,
Here is your Sample Code For XML Parsing in both VB and vc++. i hace taken this code from the MSDN
[Visual Basic]
Example
The following Microsoft® Visual Basic® example creates an IXMLDOMAttribute object from the first attribute of the root and displays the object's value and xml properties.
Dim xmlDoc As New Msxml2.DOMDocument
Dim root As IXMLDOMElement
Dim objDOMatt As IXMLDOMAttribute
xmlDoc.async = False
xmlDoc.Load ("books.xml")
Set root = xmlDoc.documentElement
Set objDOMatt = root.firstChild.Attributes.Item(0)
MsgBox (objDOMatt.Value)
MsgBox (objDOMatt.xml)
[C/C++]
Example
#import "msxml3.dll"
using namespace MSXML2;
#define CHECK_AND_RELEASE(pInterface) \
if(pInterface) \
{\
pInterface->Release();\
pInterface = NULL;\
}\
#define RELEASE(pInterface) \
{\
pInterface->Release();\
pInterface = NULL;\
}\
_variant_t varValue;
BSTR bstrAttributeName = ::SysAllocString(_T("dateCreated"));
IXMLDOMElement *pIXMLDOMElement = NULL;
IXMLDOMDocument *pIXMLDOMDocument = NULL;
HRESULT hr;
try
{
hr = pIXMLDOMDocument->get_documentElement( &pIXMLDOMElement);
SUCCEEDED(hr) ? 0 : throw hr;
if(pIXMLDOMElement)
{
varValue = _T("year 2000");
hr = pIXMLDOMElement->setAttribute(bstrAttributeName, varValue);
SUCCEEDED(hr) ? 0 : throw hr;
hr = pIXMLDOMElement->getAttribute(bstrAttributeName, &varValue);
SUCCEEDED(hr) ? 0 : throw hr;
if(varValue.vt != VT_NULL)
{
::MessageBox(NULL, _bstr_t(varValue), bstrAttributeName, MB_OK);
bResult = TRUE;
}
RELEASE(pIXMLDOMElement);
}
::SysFreeString(bstrAttributeName);
bstrAttributeName=NULL;
}
catch(...)
{
if(bstrAttributeName)
{
::SysFreeString(bstrAttributeName);
bstrAttributeName = NULL;
}
CHECK_AND_RELEASE(pIXMLDOMElement);
DisplayErrorToUser();
}
// Release pIXMLDOMDocument when finished with it.

IDS means "intrusion detection system"
|
|
|
|
|
like in alarm systems ? 
2 other people asked you the same question, you should rephrase your original question to include as much information as possible so that we can help yip ( if possible ).
