If the function can be inlined it will be, otherwise it will attempt to link to the function. This means it must exist in source somewhere. One thing to check is if a macro is used to define "extern inline" and can be turned on/off easily.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

Hi
I am looking for C program source code. Could you please help me in finding the source code of the required mentioned below.
Task that I need to complete:
Write a program to create multiple threads (one master thread and rest worker threads) and using the threads write into and read from shared memory.
Restrictions:
Only one thread should be able to read at any instant of time into shared memory region.
Only one thread should be able to write at any instant of time into shared memory region.
Worker threads should inform the master thread after every read and write operation.
Master thread inform the worker thread (which is waiting to acquire shared memory region) that read or write operation is successful and it can acquire the memory for either reading and writing operations.

You can use a mutex to limit access to shared memory to only one thread. You'll have to write the code yourself; that's the point of taking a class.

Isn't the main purpose of your class to create the code rather than find it?

What an excellent question! This is a LOT more clearerer than Globule Beats Brick! Here you go, you can write the void main() function:
char data[360];
class rthread {
char* myDataPtr;
rthread(char* ptr){
myDataPtr=ptr;
}
bool write(char* d,int size){
return memcpy(d,myDataPtr,(size>360?359:size));
}
}
class wthread {
char* myDataPtr;
wthread(char* ptr){
myDataPtr=ptr;
}
bool read(char* d, int size){
return memcpy(myDataPtr,d,(size>360?359:size));
}
}
class mthread {
char* myDataPtr;
wthread* myWriter;
rthread* myReader;
mthread(char* ptr){
myDataPtr = ptr;
wthread = new wthread(myDataPtr);
rthread = new rthread(myDataPtr);
}
~mthread(){
delete wthread;
delete rthread;
}
bool read(char* c,int size){
return myReader->read(c,size);
}
bool write(char* c,int size){
return myWriter->write(c,size);
}
}

Hi all,
So, I have an MFC app to encode files in base64 to be sent through email. Here's the code I'm using now :
filename=filename.Right(filename.GetLength()-filename.ReverseFind('\\')-1);
inputfile.Read(filedata.GetBuffer(0),inputfile.GetLength());
filedata.SetAt(inputfile.GetLength(),'\0');
emailbody+="--0000000002230291k492__V\r\nContent-type: "+fileExt+"\r\n";
emailbody+="Content-Transfer-Encoding: base64\r\nContent-Disposition: attachment; ";
emailbody+="filename=\""+filename+"\"\r\n\r\n";
emailbody+=base64_encode(filedata.GetBuffer(0)).c_str();
emailbody+="\r\n\r\n";
inputfile.Close();
I've got no clue of why this code doesn't work properly. It works fine for .txt files and other files that only contain alphanumeric chars, ONLY WHEN the files are smaller than around 5kb. Other files do not work at all, regardless of the size.
here's the base64 encode function I'm using:
inline std::string base64_encode(const std::string &sString) {
static const std::string sBase64Table(
"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"
);
static const char cFillChar = '=';
std::string::size_type nLength = sString.length();
std::string sResult;
sResult.reserve(nLength * 8 / 6 + 1);
for(std::string::size_type nPos = 0; nPos < nLength; nPos++) {
char cCode;
cCode = (sString[nPos] >> 2) & 0x3f;
sResult.append(1, sBase64Table[cCode]);
cCode = (sString[nPos] << 4) & 0x3f;
if(++nPos < nLength)
cCode |= (sString[nPos] >> 4) & 0x0f;
sResult.append(1, sBase64Table[cCode]);
if(nPos < nLength) {
cCode = (sString[nPos] << 2) & 0x3f;
if(++nPos < nLength)
cCode |= (sString[nPos] >> 6) & 0x03;
sResult.append(1, sBase64Table[cCode]);
} else {
++nPos;
sResult.append(1, cFillChar);
}
if(nPos < nLength) {
cCode = sString[nPos] & 0x3f;
sResult.append(1, sBase64Table[cCode]);
} else {
sResult.append(1, cFillChar);
}
}
return sResult;
}
This function seems to be encoding correctly, while other ones I've found or created don't encode right.
Does anyone have any advice for me? I'm about to give up on this function.

If you can accept being limited to XP and later, use CryptBinaryToString().

How do I change the shadow color in ShadowVolume(DirectX Sample Browser November 2007,July 2004)?
I want to change the color of shadow to be float4(0.7f,0.7f,0.7f,1.0f).
I mean the shadow color is not the g_vShadowColor for debug.

For example:
In CMyDocument:
std::vector<pair><float,float> m_vec;</pair>
CMyDocument::Serialize(CArchive &ar)
{
if (ar.IsStoring())
{
}
else
{
}
}

On storing : first store vector size and then each (scalar) element of the vector.
On reading: read the size of the vector, then its size elements.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

I tried following code but it working for Progess bar not for Static text.
GetDlgItem(IDC_PROGRESS1)->ShowWindow(SW_SHOW); // Working
GetDlgItem(IDC_STATIC)->ShowWindow(SW_SHOW); // Not working
Kindly provide me solution...
|
|
|
|
|
IDC_STATIC as is won't work. you have to chage it to another name, like IDC_STATIC1...
|
|
|
|
|
The IDC_STATIC is default resource id provided for controls which are usually not accessed and manipulated. For instance, static texts, GroupBox etc. If you check the value of IDC_STATIC, you can see its -1.
So, if you want to manipulate that text control, as toxcct said, change the IDC_STATIC to some other name and access it. Or else GetDlgItem() will fail.

Jijo.

I guess you've asked "how to change the background color of label". 
Well, override the CWnd::OnCtlColor() in your dialog class. This function will be called for getting the control color of each child control. See here for more detailed description and code sample - http://msdn.microsoft.com/en-us/library/0wwk06hc(VS.80).aspx[^]

Hello,
I have application which makes a call to CreateFile and return handle FILE*, I can write to the file using this handle on XP, but on vista it does not work, it creates the file, but fprintf calls returns -1.
Is there any difference of C Run time library on XP and VISTA ?
Looking forward to hear from you soon.
Many Thanks.

CreateFile() returns a HANDLE, not a FILE pointer.

Since you opened the file with CreateFile(), you should be using WriteFile(). Otherwise, you'll need to open the file with fopen().
