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!!![^] WTF | :WTF:

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 Frown | :-(

GDI+ Bitmaps

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)						// Early out if string is NULL<br />
	return xfalse;<br />
<br />
	// Convert C string to UNICODE<br />
	wideLen = MultiByteToWideChar (CP_ACP, MB_PRECOMPOSED, fileName, -1, NULL, 0);		// Get necessary length<br />
	fileNameW = (WCHAR *)malloc (wideLen);							// Alloc string<br />
	MultiByteToWideChar (CP_ACP, MB_PRECOMPOSED, fileName, -1, fileNameW, wideLen);		// Translate string<br />
<br />
	Bitmap		bmp ((const WCHAR *)fileNameW, FALSE);<br />
<br />
	...<br />

The string fileName is being properly translated to fileNameW as below:

<br />
// Original String<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 />
// Wide String<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.

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.

I do not see tga in the list of supported formats.

archiving code or binary within my prog

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

if you put that code in DLLs which are loaded dynamically (ie. using LoadLibrary, etc), you can compress them (use zLib), attach them to the end of your loader EXE.

it could be similar to this: http://www.codeproject.com/file/self_extractor.asp[^], but with the added decompression step.

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
{
   // Initialize pIXMLDOMDocument and load an
   // XML file into it.
   // Get the document root.
   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.

Launching Outlook from within a program

Hi all,

First posting from me. I'll try to be concice.

I'm writing an app. In this app I've got a button "send e-mail". When I press this button, I can start a new e-mail with the address correctly filled in by getting the mail-tool path from the Registry and using the following command line

(psuedo code - cs means a CSrring)
CString csApp = GetAppPathFromRegistry( "Outlook.exe");
csApp += "/c ipm.note /m " + csEmailAddress;

My question is, what are the command line switches to add text to the "subject" and "body" fields?

I've trawelled the net and can only find VB examples. So, it's got to be do-able. I just can't find the command line options to fill out these fields from a non-VB app.

Any help, much appreciated.

Suggested way is to use followilng:

ShellExecute(NULL,"open", "mailto:code@project.com?Subject=hi&body=its me","","", SW_SHOW );

Which takes everything as default, like email application, default mail account etc.
