Hi
I’m creating one windows service in my own purpose
Using msxml4.dll.
The process of service is to fetch the data from exchange server through webdav SEARCH METHOD
When i use this coding in windows form normal button click event , it works fine,
When I convert into windows service, it throws the error
The coding is below
MSXML2.XMLHTTP objXMLHTTP = new MSXML2.XMLHTTP();
writemethod("After Initialize");
System.Xml.XmlDataDocument xmlDOMParams = new System.Xml.XmlDataDocument();
objXMLHTTP.open("SEARCH", strInboxURL,false,strAliasName, strPassword);
objXMLHTTP.setRequestHeader("Content-type", "text/xml");
objXMLHTTP.setRequestHeader("Depth", "1");
string strXML;
strXML = "" +
"<d:searchrequest xmlns ="\'DAV:\'">" +
"<d:sql>" +
"SELECT \"urn:schemas:httpmail:fromemail\"," +
------------------
---------etc…
objXMLHTTP.send(strXML); // Error Raised
The Error Raised in when i send the xml query
Any suggestion,please reply

I use CImage class for working with bitmaps and noticed memory leak and can't understand the problem.
When i'm trying to change the content of bitmap by accessing the bytes - in different cases i see or not see memory leaks, however the code is same!
Here is the code:

I'll try to help but I can't read your posted code.
Can you wrap it in "pre" tags instead of "code" tags?
How do you know there's a leak? How are you checking?

As long as you are freeing memory you allocate you should be fine.
The task manager isn't always a great leak detector. Memory allocated for your process may
be marked as available to the application but not freed until it's necessary - for performance.
Trust your code 
The debug C runtime (CRT) will show leaks at runtime for malloc, _aligned_malloc, new, etc.

Ok! Thank You very much for participating.

hi,
I am using the following code to send a string to the notepad, without direct keyboard input(using SendInput function):
//start of code
CString str(_T("D:\\sample.gho"));
INPUT key[2];
int nLeng = str.GetLength();
for(int index=0;index < nLeng;index++ )
{
::ZeroMemory(key, sizeof(key));
key[0].type = key[1].type = INPUT_KEYBOARD;
SHORT nKeyCode = VkKeyScan(str[index]);
if (VK_SHIFT & nKeyCode)
{
key[0].ki.wVk = VK_SHIFT;
key[0].ki.dwFlags = KEYEVENTF_KEYUP;
//shift key plus char
key[1].ki.wScan = str[index];
key[1].ki.dwFlags = KEYEVENTF_UNICODE ;
}
else if (VK_CAPITAL & nKeyCode)
{
key[0].ki.wVk = VK_CAPITAL;
key[0].ki.dwFlags = KEYEVENTF_KEYUP;
//capital key plus char
key[1].ki.wScan = str[index];
key[1].ki.dwFlags = KEYEVENTF_UNICODE ;
}
else
{
key[1].ki.wVk = nKeyCode;
key[1].ki.dwFlags = KEYEVENTF_UNICODE ;
}
key[0].ki.time = key[1].ki.time = 0;
key[0].ki.dwExtraInfo = key[1].ki.dwExtraInfo=0;
SendInput(2,key,sizeof(INPUT));
}
//end of code
But, unfortunately, I gets an error:
'KEYEVENTF_UNICODE' : undeclared identifier
Please help me.
Thanks in advance.

MSDN say, that KEYEVENTF_UNICODE used for Windows 2000/XP only.
In winuser.h you can see
#if(_WIN32_WINNT >= 0x0500)
#define KEYEVENTF_UNICODE 0x0004
#define KEYEVENTF_SCANCODE 0x0008
#endif /* _WIN32_WINNT >= 0x0500 */
So, if you are realy in Win2000 or XP...
Look in file stdafx.h.
I work in XP, and I have next line in stdafx.h :
#ifndef _WIN32_WINNT
#define _WIN32_WINNT 0x0400
See? Change this on
#define _WIN32_WINNT 0x0500
#endif
May be it'll help for you
Best regards,
Baron

Thanks a lot.
Actually
#define KEYEVENTF_UNICODE 0x0004
#define KEYEVENTF_SCANCODE 0x0008
these lines were not present in my winuser.h file.
So I added these in that file, and the application is now working fine.
Once again,,thanx

Hi,
I have a text file which its contents in has to be loaded into an array. The content in the.txt file has some spaces between them and it is also a few lines long(separated by '\n'). May i know how to copy the whole file into an array?
Thank you for any help.
|
|
|
|
|
i'd suggest you to turn to C++ solutions instead of sticking to C.
by the way :
char pszBuffer[NUMBER_LONG_ENOUGH];
::fscanf(myOpenedFile, "%s", pszBuffer);
|
|
|
|
|
I can't use this method, somehow the character save in the file turns out to be in funny shapes and not the ones i input. Below is the code i used.
FILE *stream;
stream = fopen( "Result File.txt", "w+" );
char pszBuffer[500]; ::fscanf(stream, "%s", pszBuffer);
|
|
|
|
|
hey, you open the file writable, not readable... 
|
|
|
|
|
sorry mistakes, just a beginner...
but if i change w to r,it still does not help. btw, i need to put it in array of characters for it to work.
|
|
|
|
|
You can use ifstream for that purpose. You can extract formatted data from the stream by using the extraction operator ( >> ).
ifstream myFile("MyFile.txt);
int iValue;
myFile >> iValue;
See here[^] for more info.
EDIT: when looking at toxcct answer, I'm wondering: your file contains only pure text that you want to load into a string or does it contain numeric values that you want to load into an array (like an integer array) ?

|

i want get characters from the file and put it in one array. Can i use getline or other functions. This array must be able to save the file content exactly because i want to use the array to save it in another file at a specified location or path.

Try using CString.

what are you trying to do with all these lines of code ?
the OP only wants to read his file in a buffer !

It seems to generate these error:

have you that:
