The specification for syslog() is
void syslog(int priority, const char *format, ...);
and your call uses buf as the format parameter, but its content does not contain any format control characters, and your call does not include any parameters. If you rewrite it as
syslog(level, "%s", buf);
it should work OK.

I do an example to emulate keyboard with SendInput. Here is the code to press "a" with "dwFlags = KEYEVENTF_UNICODE".
Code:
INPUT inp[2];
memset(inp,0,2*sizeof(INPUT));
inp[0].type = INPUT_KEYBOARD;
inp[0].ki.dwFlags = KEYEVENTF_UNICODE ;
inp[0].ki.wScan = "a";
inp[1] = inp[0];
inp[1].ki.dwFlags |= KEYEVENTF_KEYUP;
SendInput(2, inp, sizeof(INPUT)); // Press "a"
Do you know how to press "a" with dwFlags = 0 and ki.wVk = "virtual key of a" ?
Thanks and regards.

Hi all,
I am developing a project like abode reader, I have a problem:
I need to display the ".pdf" file in the full screen model, and I have no idea to implement it.
Did anyone do it or could you tell me the main idea?
Thanks in advance.

Do you want to implement another PDF reader from scratch? or do you want to use Acrobat to show a PDF in full screen?

Yeah, I'm making my own application to implement adboe reader, now I need some thought how to
complete the full screen model.
|
|
|
|

See here[^] for the options to resize your window.
However, if you are saying that you have no idea how to write a PDF reader then I suggest you do some research into the PDF libraries that are available. There may also be some articles here on CodeProject that show you the basics.

Thank you, guys. I am making my own pdf reader, if you have some links to resource or source code, I should really thank you! 
|

|

Did you read my answer? I have given you some suggestions how to find free libraries to handle PDF files. You can also get the full PDF specification from the Adobe web site and code the whole thing yourself.

I think you can just launch PDF reader( using shellexecute or similar apis) with the pdf file name as arguemnt. you can also set the screen mode(maximaized ,minimaized , or normal ) in there.
If you want to launch PDF in your app, try PDF activex , or you can use std web browser control to shows the pdf.
hopes this helps.
If u can Dream... U can do it

Thank you, but I have a application that parse .pdf and other files, so I want to implement the
full screen model in my own frame, so I need some main ideas about this function.
|

|
|

This is something else I gave you a link for in my answer above. Try reading the link and see how easy it is to show your window in full screen mode.

these code is :
int sum(int a, int b);
#include "In.h"
int sum(int a, int b)
{
return (a+b);
}
//test05.cpp
#include "iostream"
#include "In.h"
using namespace std;
int main()
{
int a = sum(1, 2);
cout << a << endl;
}
when i complier test05.cpp, it will have a question :
~/cpp/test$ g++ -o test05 test05.cpp
/tmp/ccW55H4p.o: In function `main':
test05.cpp text+0x19): undefined reference to `sum(int, int)'
collect2: ld returned 1 exit status
give me some advides
thank you

You need to include In.cpp in your build thus:
~/cpp/test$ g++ -o test05 test05.cpp In.cpp

You're welcome. If you get bored some dark night you might want to read some of the documentation on g++, I think g++ --help gives you quite a lot of information.

Dears,
Could you please clarify whether the InterlockedIncrement API can be used in interprocess communication?
Regards,
Krishnakumar
|
|
|
|
|
In my opinion you can definitly use it. It provides synchronized access to a variable that is shared by multiple threads. In interprocess communication and to handle variables in shared memory it is safe.
|
|
|
|
|
InterlockedIncrement This API increments the variable value by 1, in addition to this, it also gives thread safety while incrementing so that we need not to write thread synchronization code just to increment counter. Now this behaviour you can use where ever you find it useful.
Thanks,
Anand.

Hey folks,
Anyone know what I need to do to get the tab key to move from field to field in a CPropertyPageImpl-based property sheet page? it works fine in design view in VS, but sounds a bell and stays put when executing. All the necessary controls have the WS_TABSTOP set, but the focus doesn't move...
Thanks!

i'm not so familar with wtl - but it sounds cause the IsDialogMessage() function is callin' twice.
override the TranslateAccelerator function to set the focus by your own. because windows cannot (will) set focus among nested dialogs. but i'm not shure if there isn't a possibility to do that on another way.
|

|
|
|
I'll look into that; thank you!

Hi,
Your message loop must call PropSheet_IsDialogMessage() when the PropSheet is not modal.
For instance in a parent frame deriving from WTL::CMessageFilter:
virtual BOOL PreTranslateMessage(MSG* pMsg)
{
return CFrameWindowImpl<CMainFrame>::PreTranslateMessage(pMsg) ? TRUE :
PropSheet_IsDialogMessage(<My Property Sheet member>.m_hWnd, pMsg);
}

I have this :
struct struct_X
{
struct_X() :
nX(0)
{
}
int nX;
CString m_strName;
};
struct_X *ptrX1=NULL;
struct_X *ptrX2=NULL;
i have a loop like this :
for(int Idx = 0; Condition; Idx++)
{
...
...
if(nCount==0)
ptrX1= new struct_X;
else
ptrX1=ReallocArray((nCount+1), nCount, ptrX2); // copy the content of ptrX2 to ptrX1 and delete ptrX2 (**)
if(ptrTmp==NULL)
break;
ptrX2=ptrX1;
ptrX2[nCount].nX = 1;
ptrX2[nCount].m_strName = strTempName; // Here I have an a crash related to CString acces violating
nCount++;
}
in the first loop ( nCount = 0) there is no problem
but after the ReallocArray (**) i get the problem in ptrX2[nCount].m_strName
Have any one idea how to solve this?

Hi,
Looks like a problem with your ReallocArray().
ATL::CString and MFC CString are simply typedef ATL::CStringT<TCHAR> CString; so at first your code may be crashing because of a wrong TCHAR type.
Anyhow you should always use the CString copy operator and not try to manipulate internal data structures as you do.
cheers,
AR

ReallocArray()
just get the ptrX2 and copy its elements to the new array ptrX1 which has number of ptrX2's elements + 1
and then delete ptrX2.
So I think the problem is no related to this.
I agree that there is problem somewhere in CString opreation but where
