call these two functions like so (adjust the filepath)... (This appears to work)
PerformTask();
PerformTask2();
void CTestfileDlg::PerformTask()
{
CString sFilePath="c:\\temp\\list.txt";
CStdioFile file;
CString sOutput="0000000000111111111122222222223333333333444444444455";
int nCount=sOutput.GetLength();
try {
if (file.Open(sFilePath,CFile::modeReadWrite|CFile::modeCreate)) {
for (int i=0;i<nCount;i+=10) {
file.WriteString(sOutput.Mid(i,10)+"\r\n"); // Append text
}
file.Close();
}
}
catch (CException * e) {
e->ReportError(); // Popup description of exception
e->Delete(); // Clean up.
}
catch (...) { // Catch any other exceptions
AfxMessageBox("Failed to open file!");
}
}
void CTestfileDlg::PerformTask2()
{
const int sz=100;
char buf[sz];
CString LString;
m_AListCtrl.ResetContent();
CString Filename = "C:\\temp\\list.txt";
ifstream ListFile( Filename );
while( ListFile.get ( buf,sz ) )
{
ListFile.get();
LString = (LPCSTR)buf;
m_AListCtrl.AddString(LString);
}
}

We are using the XListCtrl from code project and would like to have multiple lines in a column for tool tips. I have tried \r\n and I have looked at some other information in code project and else where. When a particular row/column has the mouse over it to have a tool tip appear but possible have multiple lines. the lines could be 80+ characters if we could. Could someone point me to a simple and quick solution?
thank you

I use "\n" for a newline in balloon tooltips. Not sure if this works for standard but I thought I'd post it in case you hadn't tried it yet.

I just verified that it works for both types of tooltip...
m_ToolTip.Create(this,TTS_BALLOON); // Balloon
m_ToolTip.Create(this); //for no balloon

What does the XListCtrl use for it's tooltips? I would have guessed it used CToolTipCtrl internally but I guess not.
Sorry about the misinformation then. That'll teach me to make assumptions.

In XListCtrl too it has normal tool tip, ther is no tool wrapped text inside the tooltip. I have tried in XListCtrl too by putting "\n" and "\r\n" to make the text wrap. but I failed to do that

I have a Check Box and a OnTimer
while i run my application , when i press the Check Box it get the TRUE (looks as checked) but after 2 sec (OnTimer tick) it is become unchecked (FALSE)
Any way to avoid that?
|
|
|
|
|
What I guess is that you have called the funtion
UpdateData in the OnTimer funtion.
check for that.

Handle On CLick Event on The CheckBox and Call UpdateDate(TRUE);

I beg your pardon in advance for asking such a question.
How do I save the contents of the Rich Edit View that a user types? Is there a variable that holds this information or do I have to create it - if so how?
Also, how do I send text out to the Rich Edit View? I tried to get a Device Context then use dc.TextOut(...) but it didn't work. Any ideas?
Thanks in advance,
BP

Hi all,
suppose I have a XML that is represented by the following string:
<tag a="1" b="2">
notice this xml doesn't have the regular xml header ( the tag that begins with <xlms=...>)
if i call the IXMLDOMDocument method loadXML, it fails...i think it is because the string lacks the tag <xmls...>... i heard there is a propery of IXMLDOMDocument i can set that it won't need the tag <xmls..>...but i don't know what it is
can some1 help?
thanks in advanced
Yaron

Hi
The LoadXML funtion fails if the XML is having error. In your case there is no end to the tag you provide.
Load any one of <tag a="1" b="2"></tag> or <tag a="1" b="2"/> and hope you won't have problem; though I haven't tested it myself.
Regards
Anil

Ok if this is the case I want to confirm one more thing.
Since you are using IXMLDOMDocument, have you initialize the pointer with statement like this?
SUCCEEDED (CoCreateInstance(CLSID_DOMDocument,
NULL,
CLSCTX_INPROC_SERVER,
IID_IXMLDOMDocument,
reinterpret_cast<void**>(&m_pDoc))));
m_pDoc->loadXML("<a></a>");
Regards
Anil

yes i did
i know there is a IXMLDOMParseErrorPtr object which i can get the error that has occurred but i can't seem to get it properly....

the bellow code working fine with me.
IXMLDOMDocument *m_pDoc;
m_pDoc = NULL;
if ( SUCCEEDED (CoCreateInstance(CLSID_DOMDocument,
NULL,
CLSCTX_INPROC_SERVER,
IID_IXMLDOMDocument,
reinterpret_cast<void**>(&m_pDoc))))
{
m_pDoc->loadXML("<a></a>");
}
and also the bellow code
{
HRESULT hResult = E_FAIL;
long lErrorCode = E_FAIL;
IXMLDOMParseError *pXMLError = NULL;
if (SUCCEEDED(m_pDoc->get_parseError(&pXMLError))
&& SUCCEEDED(pXMLError->get_errorCode(&lErrorCode))
&& ( lErrorCode != 0 ) )
{
// do some error report procedure
}
//
// Clean-up pointers used.
//
if ( pXMLError )
{
pXMLError->Release();
pXMLError = NULL;
}
//
// Pass back the return code.
//
return lErrorCode;
}
Regards
Anil

What type of string are you trying to load the DOM with?

CString which is cast to _bstr_

Regarding the null terminating character being embedded within a source/custom resource (input string) , I'm having some difficulty getting fwrite to continue past embedded 0x00 values in my data...
Someone posted elsewhere on this site:
It acted like it continued beyond the end of the array until it came across the zero byte in memory. I put the "\0" or the 0x00 and it stopped exactly where I told it too. This raises the question, if that array is supposedly a hex representation of an exe, how are you getting away without stumbling across 0x00 somewhere in the binary string? this is one of the reason they tell us to encode binary data when using a null terminated string to contain it.
My code:
CODE
char * cStr = reinterpret_cast< char *>(lpVoid);
cStr = strncat(cStr, "\0", 1);
printf("size of cStr%d\n", sizeof(cStr));
FILE * stream;
if( (stream = fopen( "fread.out", "w" )) != NULL )
{
int num_write = 0;
num_write = fwrite( cStr, sizeof( cStr ), 1, stream );
printf( "Wrote items: %d\n", num_write );
fclose( stream );
}
Results:
follwing were writing sizeof(cStr) - 1 (not wanting to write the trailing null to our output file):
testing: 4d 5a 90 as input, output: 4d 5a 90 (OK)
testing: 4d 5a 90 00 as input, output: 4d 5a 90
testing: 4d 5a 90 00 03 as input, output: 4d 5a 90
testing: 4d 5a 90 03 as input: output: 4d 5a 90
writing sizeof(cStr) :
4d 5a 90 -> 4d 5a 90 00
4d 5a 90 00 -> 4d 5a 90 00
4d 5a 90 00 03 -> 4d 5a 90 00 (stripped trailing character)
Anyone have any suggestions on how to proceed?
How will the program know the difference between the trailing null at the end of the string versus embedded nulls?

There are two problems. First, cStr is a pointer, so sizeof(cStr) will always be 4 no matter what it's pointing to.
Second, strncat(cStr, "\0", 1) has no effect. A \0 character marks the end of a string, so "\0" is the same as "", a string with zero length.
