Hi all,
I have an application that executes several command line tools in the background (i.e no command line window is openend).
I still like to get the output from the tools and I've got no problem capturing output from printf and all fprintf's to stdout, stderr.
The problem is that I can't find a way to capture outputs made with cprintf.
I do not have access to the source of all tools (some are very old) so there's no way that I can change the tools to use printf.
I'm quite sure that someone must have done this, doing custom command line windows etc.
Are there any source available for a one of thoose?
Any hints are welcome..

if you want a command line solution, here is how you can do it.
myprogram 2> error.log
the 2> directs the error stream to the file error.log

As far as i remember, it's like this:

(And < redirects a stream to stdin).

Thanks you guys, but it still doesn't solve any of my problems.
I'm NOT trying to redirect output to a file, I'd like to capture the output from my Win32 program that executes the command line tools (without showing any command line window).
The redirections doesn't redirect the cprintf outputs anyway.
Consider the following test application:
<br />
#include <conio.h><br />
#include <stdio.h><br />
<br />
void<br />
main(void)<br />
{<br />
printf("This line is printed using printf(...)\n");<br />
cprintf("This line is printed using cprintf(...)\n");<br />
fprintf(stdout, "This line is printed using fprintf(stdout, ...)\n");<br />
fprintf(stderr, "This line is printed using fprintf(stderr, ...)\n");<br />
}<br />
Running this with some redirections give:
<br />
T:\>test.exe<br />
This line is printed using printf(...)<br />
This line is printed using cprintf(...)<br />
This line is printed using fprintf(stdout, ...)<br />
This line is printed using fprintf(stderr, ...)<br />
<br />
T:\>test.exe > temp.log<br />
This line is printed using cprintf(...)<br />
This line is printed using fprintf(stderr, ...)<br />
<br />
T:\>test.exe 2> temp.log<br />
This line is printed using printf(...)<br />
This line is printed using cprintf(...)<br />
This line is printed using fprintf(stdout, ...)<br />
As you see it's impossible to capture ALL output.
(Btw is there a way to capture both stdout and stderr to the same file and preserve the order?)
From my Win32 program I can capture all cases except the cprintf one.
So I'll ask again if anyone have some hints on how to do it since I'm quite sure it's doable, cmd replacements like 4NT seems to handle that.

Hi Friends,
I have one window on which I want to display SSN. SSN is one of the option in list and it value display infront of it in edit box. Can you pls help me to display these scenario. I am new to windows programming.
Thanks

Iterate through the items of the list box using the GetCount().
Create an array of the edit box's in front of the boxes.
Dpeneding on the count of the list go on setting the corresponding values of the list box into the edit boxes.
Somethings seem HARD to do, until we know how to do them.

Thank you for help. I am looking for exactly same answer. Do i really need to travese all the list? Since we know when list show SSN,set the value in edit box.Is it possible to reach directly to index of SSN in the list and same for edit box?
Thanks

I didn't get what you need to do exactly?
May be you want to have a look at the LBN_SELCHANGE event of the list box.
Also list box is shown at the time of initdialog and so you can put some of your code over there.
Does this solve your problem?

what do you need?
show value from ListBox or show value in editbox
for show text in editbox use m_Edit1.SetWindowText("text");
for read from listbox use m_List1.GetText(m_List1.GetCurSel(),str)

Pls be more specific. the last sentences are not clear.
u can SetWindowText to set a window text.
either u may have to create control varibles (string variable) for the controls u put in the the window or use GetDlgItem to get window handle.
check MSDN for more info

U can make use of the function GetCurSel() to get the current selected item index. Now you can use GetText(index,string) to get the selected item text into the string. Set the retrieved string into the Edit box using SeWindowText().

my code
const int sz=100;
char buf[sz];
CString LString;
m_AListCtrl.ResetContent();
CString Filename = "C:\\Documents and Settings\\Owner\\list.txt";
ifstream ListFile( Filename );
while( ListFile.get ( buf,sz ) )
{
ListFile.get();
LString = (LPCSTR)buf;
m_AListCtrl.AddString(LString);
}
the problem is it doesnt read my last Line in the Text
(my Text's Form)
xxxx
yyyyy

I took your snippet as is and ran it against a notepad file with 4 lines of text.
It populated the ListBox with all 4 lines even if I removed the last newline. Not sure what might be different on yours. Was your list.txt file created manually with notepad?

no a previous function create it/Edit it
if (file.Open(sFilePath,CFile::modeReadWrite|CFile::modeNoTruncate|CFile::modeCreate))
{
CString str = "\n"+Filetitle+".mp3";
file.SeekToEnd();
file.WriteString(str);
file.Close();
}

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.
