Hi
No ... Sorry ...
CDEVICE is initialised in the myAppView Constructor, but the work starts after clicking a menu buttom
for example:
<br />
void startWork()<br />
{<br />
doA();<br />
doB();<br />
doC();<br />
}<br />
or
<br />
void startWork()<br />
{<br />
doB();<br />
doA();<br />
doC();<br />
}<br />
I tried all combinations the error allways comes at returning from doA()??!??!!
Any suggestions ?

FILE *Ofile;
<br />
int fCnt = 0;<br />
sprintf(gz_op_fname,"TargetStatistics%d.txt",fCnt);<br />
while ((Ofile = fopen(gz_op_fname, "r")) != NULL)<br />
{<br />
sprintf(gz_op_fname,"TargetStatistics%d.txt",++fCnt);<br />
fclose(Ofile);<br />
}<br />
I have the above code to create a file TargetStatistics%d.txt.
ie. if TargetStatistics0.txt, TargetStatistics1.txt already exists, then TargetStatistics2.txt will be created.
But sometimes with this code I get Invalid handle exception in the while loop.
and I occurs often when there are more files, say it has to create TargetStatistics20.txt.
Whats the problem here. Thanks in advance.

Which line do you suppose is going to create the file within yor piece of code?

oops..sorry I didnt include the part of code that creates the file.
But the exception is surely occuring in the while loop that I had shown in my previous post, for i checked with outputdebug messages. I also included a debug message inside the while loop, and every time its happening after TargetStatistics5.txt or TargetStatistics6.txt.
Thanks.

Could you provide the loop as it is? More chances for real help

... and also, how is gz_op_fname declared?

<br />
char gz_op_fname[100];
...<br />
OutputDebug("Data Acq\n");<br />
<br />
sprintf(gz_op_fname,"TargetStatistics%d.txt",fCnt);<br />
while ((Ofile = fopen(gz_op_fname, "r")) != NULL)<br />
{<br />
OutputDebug(gz_op_fname);<br />
sprintf(gz_op_fname,"TargetStatistics%d.txt",++fCnt);<br />
fclose(Ofile);<br />
}<br />
<br />
OutputDebug("Search Op file \n");<br />
these are the debug messages...

Have you tried single-stepping through the code and noting the value of gz_op_fname when the exception is thrown? Is the variable large enough (e.g., MAX_PATH).

If I do single stepping this exception does'nt occur.

Does the following help:
FILE *pFile;
char szFilename[MAX_PATH];
int nCount = -1;
do
{
nCount++;
sprintf(szFilename, "TargetStatistics%d.txt", nCount);
} while (_access(szFilename, 0) == 0);
pFile = fopen(szFilename, "r");
...
fclose(pFile);

Sure that helped...Thanks a bunch.
Also I tried with Sleep(50) before fclose (inside the while loop-in my code from the previous posts) and it "seemed" to solve the problem.
interesting hun!!!!!

Not really. I suspected it had something to do with too many file open/close requests hence my suggestion for only one.

Hi
I have implemented the code to produce tooltips for my listboxes using the article http://www.codeproject.com/combobox/cexlistboc.asp. This works fine for lists that are contained in CWnd windows. However, it does not work when my lists are contained in a CDialog. Any ideas on how to get this to work when the list is in a CDialog window ?
Thanks
|

Thanks, but I've seen that one already. The tool tips I'm displaying for the list are specific to the row and column that the pointer is over. I need the tooltips to be specific to the list control, as they are now when it's used outside a dialog. Remember, this works fine (like the demo) when I use the list on a regular frame window.

Hello,
could it be possible to get a notification message when user presses Enter with the Editbox selected. If user hits Enter, it should get the editbox's text and write it into a Textbox..
All suggestions are welcome,
Thank You..
|
|
|
|

<br />
CWnd* pWnd = GetFocus(); <br />
<br />
if(pWnd->GetDlgCtrlID() != IDOK) <br />
{<br />
if (pWnd->GetDlgCtrlID() == IDC_MYEDITBOX)<br />
}<br />
<br />
CDialog::OnOK();<br />
|
|
|
|
|
Thank You..
Seems that i posted it into a wrong discussion board.. 
Win32 API without MFC would be a bit more helpful for me as i'm using DevC++ and i don't know what equals to CDialog::OnOK();
All suggestions are welcome,
Thank You..

here is Shay Harel code converted.
case IDOK:
HWND hWndChild = GetFocus();
if( hWndChild != GetDlgItem(hWnd, IDOK) )
{
if( hWndChild == GetDlgItem(hWnd, IDC_MYEDITBOX) )
// do something;
}
|
|
|
|
|
and with message WM_COMMAND and switch (LOWORD(wParam)) ?
Why could if( hWndChild != GetDlgItem(hWnd, IDOK) ) be needed if the second one checks for a window in focus?
With this switch i get a notification even if user clicks on the editbox.
Is it possible to check HIWORD(wParam) for a mouseclick when the control is an editbox?
Do i have to use ES_MULTILINE | ES_WANTRETURN flags when creating the editbox in order to make the control even receive a notification about Enter?
Unfortunately i see no changes after adding these flags..
WinInf.EditBox = CreateWindow ("edit", "", WS_CHILD | WS_VISIBLE | <br />
ES_LEFT | ES_NOHIDESEL | ES_MULTILINE | ES_WANTRETURN,<br />
WinInf.ClientRect.left + 2,<br />
WinInf.ClientRect.bottom - 20,<br />
WinInf.ClientRect.right - 4, <br />
20,<br />
hwnd, (HMENU) 1, WinInf.hInst,<br />
NULL);
All suggestions are welcome,
Thank You..

You are making this much harder than it needs to be. This is a very easy thing to code. The following code does exactly what you need. All you have to do is copy it into your code and it will work. You don't need to mess around with the create options. The reason it works is because the IDOK button will be a default button, and will be called when the return is pressed.
case WM_COMMAND:
{
switch(LOWORD(wParam))
{
case IDOK:
{
HWND hWndChild = GetFocus();
if( hWndChild != GetDlgItem(hDlg, IDOK) )
{
if( hWndChild == GetDlgItem(hDlg, IDC_EDIT1) )
{
char szText[128];
GetWindowText(hWndChild, szText, sizeof(szText));
SetWindowText(GetDlgItem(hDlg, IDCS_TEXT), szText);
return TRUE;
}
}
EndDialog(hDlg, LOWORD(wParam));
}
return TRUE;
